Answer:

5y + 8 < 23  and y < 3

2c - 3 = 9

Step-by-step explanation:

She bought a jewelry at a craft fair . The necklace is $8 and the bracelet is $5 each. Her total expenses is $23.

She bought a single necklace. The number of bracelet she bought is unknown but each of the bracelet she bought is $5 each. The number of bracelet she bought can be represented below.

Let

y = number of bracelet bought

Therefore, the cost of the total number of bracelet will be 5y

Recall the total expenses is $23

5y + 8 < 23  and y < 3

if you insert the value of y in the following inequalities the resulting value should be less than 23 so the value of y should be less than 3.

2. 2c - 3 = 9

Answer:

So the z-scores that separate the unusual IQ scores from those that are​ usual are Z = -2 and Z = 2.

The IQ scores that separate the unusual IQ scores from those that are​ usual are 84 and 148.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 116, \sigma = 16[/tex]

What are the z scores that separate the unusual IQ scores from those that are​ usual?

If Z<-2 or Z > 2, the IQ score is unusual.

So the z-scores that separate the unusual IQ scores from those that are​ usual are Z = -2 and Z = 2.

What are the IQ scores that separate the unusual IQ scores from those that are​ usual?

Those IQ scores are X when Z = -2 and X when Z = 2. So

Z = -2

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-2 = \frac{X - 116}{16}[/tex]

[tex]X - 116 = -2*16[/tex]

[tex]X = 84[/tex]

Z = 2

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]2 = \frac{X - 116}{16}[/tex]

[tex]X - 116 = 2*16[/tex]

[tex]X = 148[/tex]

The IQ scores that separate the unusual IQ scores from those that are​ usual are 84 and 148.

Answer:

[tex]\mu -2*\sigma = 116-2*16= 84[/tex]

[tex]\mu +2*\sigma = 116+2*16= 148[/tex]

Step-by-step explanation:

We know that the distirbution for the IQ have the following parameters:

[tex]\mu=116, \sigma=16[/tex]

The z score is given by this formula

[tex] z = \frac{X -\mu}{\sigma}[/tex]

And replacing the limits we got:

[tex] X = \mu \pm z \sigma[/tex]

For this case we know that a value to be unusual if its z score is less than minus2 or greater than​ 2, so then we can find the limits with this formulas:

[tex]\mu -2*\sigma = 116-2*16= 84[/tex]

[tex]\mu +2*\sigma = 116+2*16= 148[/tex]

Answer:

Population: all company employees.

Sample: arrival times of the employees during the data collection.

Step-by-step explanation:

In this case, the population is the group about which the company wants to estimate a parameter (proportion of employees who are at least 1 minute late for work). This group is all employees of the company.

The sample is comprised of the arrival times of the individuals who went to work during the data collection by the entry time recording machine. The proportion of the sample is calculated on these arrival times, with which the proportion of the population will be inferred.

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]4x + 4 = -7 +2x +19[/tex]

[tex]4x + 4 = 2x +12[/tex]

[tex]4x-2x=12-4[/tex]

[tex]2x=8[/tex]

[tex]x=8 \div 2[/tex]

[tex]x=4[/tex]

Step 1: Simplify both sides of the equation.

4x+4=−7+2x+19

4x+4=(2x)+(−7+19)(Combine Like Terms)

4x+4=2x+12

4x+4=2x+12

Step 2: Subtract 2x from both sides.

4x+4−2x=2x+12−2x

2x+4=12

Step 3: Subtract 4 from both sides.

2x+4−4=12−4

2x=8

Step 4: Divide both sides by 2.

2x/2 = 8/2

Description:

The first step is to Simplify both sides of the equation, when you do it correct and follow the steps above you equation will end up 4x+4=2x+12. For steps 2 Subtract 2x from both sides, when you do it correct your equation will end up like 2x+4=12. For step 3 you  Subtract 4 from both sides, when you do it correct equation will end up like 2x=8. Last step is to Divide both sides by 2, when you do it correct your answer will come as x=4 .

The different transformations have been matched to their respective operations below.

Parent function is given as: f(x) = 2x - 6

Thus, the transformations are:

When f(x) shifts 4 units down, we have;

f(x) → f(x) - 4

⇒ g(x)= 2x - 6 - 4 = 2x - 10

When it stretches f(x) by a factor of 4 away from the x-axis;

f(x) → 4*f(x)

⇒ g(x) = 4(2x - 6) = 8x - 24

When it shifts f(x) 4 units right;

f(x) → f(x - 4)

⇒ g(x) = 2(x - 4) - 6 = 2x - 14

Answer:

Beginning Cash balance was $4,640.

Step-by-step explanation:

Net cash flow from operating activities =      $19,600

Net cash flow used in investing activities = ($10,800)

Net cash provided by financing activities =  $12,960

Net increase in cash                                      $21,760

Beginning cash balance = Closing balance  ($26,400) less net increase in cash ($21,760)  = $4,640

The increase in cash represents the cash that was generated from operating, investing, and financing activities.  These three activities are the classifications of an entity's activities.  Operating activities are those activities that are normal to the business, i.e. activities the business undertakes under its mission.  The investing activities arise from the purchase and sale of investments.  These are not normal activities of most entities, except investment companies.  Financing activities are activities engaged by an entity to raise finance, including the repayment of the borrowed funds plus interest.

Answer:

An acute angle is an angle that has a measure that is less than 90 degrees. Any measure that is less than 90 degrees could be an acute angle. For example, 8°, 15°, °26°, and 89° are all acute angles. Anything that is 90 degrees is a right angle and greater than 90 degrees is an obtuse angle. An acute angle can have all of the following measures except 90 degrees or greater than 90 degrees.

Answer:

0 is not an acute angle

Step-by-step explanation:

if the measurement of an angle is between 0 and 90 degrees then we called it an acute angle. it means acute angle is greater than 0 and less than 90 degrees. among the the other options it is between 0 and 90 therefore 0 is not it

B. h(x) = 2x^2 - 3x + 3

Step-by-step explanation:

Given

f(x)=3x+5

g(x)=2x^2 - 6x - 2

h(x) is sum of the functions f(x) and g(x)

Thus,

h(x) = f(x) + g(x)

substituting value of f(x) and g(x) as given above we have

h(x) = 3x+5 + 2x^2 - 6x - 2

as ( 3x - 6x = -3x and 5- 2 = 3) , we have

h(x) = 2x^2 -3x + 3

Answer:

13 ppl choose both

Step-by-step explanation:

Hello,

In a restaurant 40% of the customers choose Chinese food

while 65% opt for Pakistani food.

if the restaurant is visited by 260 people then how many opt for both ?

There are 260 people we need to compute

40% of 260 = 40*260/100 = 104 to know the customers choosing Chinese food

65% of 260 = 65 * 260/100 = 169  to know the customers choosing Pakistani food

There are ppl choosing both Chinese and Pakistani, let s note x

we can say that 104 + 169 -x = 260

so x = 273-260=13

in conclusion, 104-13=91 ppl choose Chinese food only

169-13=159 ppl choose Pakistani food only

13 ppl choose both

in total there are 91 + 159 + 13 = 260

hope this helps

The number of people who opt for both Chinese and Pakistani food is 13.

We have,

Let's denote the number of people who choose Chinese food as "C" and the number of people who choose Pakistani food as "P".

We are given that 40% of the customers choose Chinese food, which means

C = 40% of 260.

C = 0.4 * 260

C = 104

Similarly, we are given that 65% of the customers opt for Pakistani food, which means

P = 65% of 260.

P = 0.65 * 260

P = 169

Now, we need to determine the number of people who opt for both Chinese and Pakistani food.

To find this, we can use the principle of inclusion-exclusion.

The total number of people who opt for both is given by:

Total = C + P - Both

We know that the total number of customers is 260, so:

260 = 104 + 169 - Both

Rearranging the equation to solve for Both:

Both = 104 + 169 - 260

Both = 273 - 260

Both = 13

Therefore,

The number of people who opt for both Chinese and Pakistani food is 13.

2) Attached. Skewed.

3) C. Skewed right

4) The values 0 and 1 would be unusual because the associated probabilities are lower than 0.3%.

Step-by-step explanation:

1) A binomial distribution for this case can be constructed with the parameters n=5 and p=0.84.

The probability of k adults from the sample respond Yes is:

[tex]P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}=\dbinom{5}{k} 0.84^{k}\cdot 0.16^{5-k}[/tex]

Answer: Liquid B is warmer.

Step-by-step explanation:

The data that we have is:

Temperature A = -105.4° C

Temperature B = -10.83° C

We want to know which liquid is warmer, this is equivalent to see which temperature is bigger, Ta or Tb.

Now, you can see that temperature A is larger in module, but this is a negative number.

When we work with negative numbers, the bigger ones are the ones closer to zero. This means that for example, -1 is larger than - 150.

From this, we can conclude that Liquid B is warmer.

Another way to see it is with a change of units.

If we have A degrees Celcius, and we want to to transform it into Kelvins, we must add 273.15°.

Then we have:

Ta = (-105.4° + 273.15°) K = 167.75 K

Tb = (-10.83 ´273.15°) = 262.35 K

where you can see that liquid B has a larger temperature.

Answer:

Liq A= -105.4ºC < LiqB= -10.83ºC

Step-by-step explanation:

Hello!

The easiest and quickest way to compare two negative values and determine which one is greater is by sorting them in a number line. (Check attachment)

You can also compare the absolute value of the temperature measurements. |10.83| < |105.4|. As the negative value decrease, the absolute value increases.

So the temperature of Liquid B > Temperature of liquid A.

Answer:

41

Explanation:

To solve this problem we must first understand what the pattern is in the arithmetic sequence. Once we understand the pattern, we can then apply it to the final known term to find the next term.

Take a look at the arithmetic sequence given:

9, 17, 25, 33,...

Let's start by figuring out how they got the second term in the sequence. To do that, subtract the second term by the first term. This will reveal the pattern.

9 - first term

17 - second term

17 - 9 = 8

So, this means they added eight to get the next term. Therefore, the pattern should be 'add eight' to get the next term. Just to be sure the pattern we found is correct, apply it to the given arithmetic sequence.

9, 17, 25, 33,...

9 + 8 = 17

17  + 8 = 25

25 + 8 = 33

So, since 'adding eight' every time gives us the next term, the pattern is correct.

Finally, let's continue the pattern to find the next term.

9, 17, 25, 33,...

33 + 8 = 41

9, 17, 25, 33, 41,...

Therefore, the next term in the arithmetic sequence is 41.

Since chi-squared calculated value is greater than p-value, there is a relationship between vaccine location and severe reaction.

Answer:

Step-by-step explanation:

This survey is testing for an association between the vaccine location and severe reactions using the chi-square test of independence.

Null hypothesis: Vaccine location and severe reactions are independent

Alternative: Vaccine location and severe reactions are not independent

With a chi square test statistic of 2.0609 with a P value of 0.1511. Using the p- value in comparison to either α = 0.05 or 0.01, the pediatricians can fail to reject the null as the p-value is greater than 0.05 or 0.01 and can conclude that there is a statistically significant association between vaccine location and severe reaction.

This approach was appropriate because the sampling method was simple random sampling, the variables that were under study were categorical, and the expected frequency count was at least 5 in all values to be able to reach  value of 283 and 289.
