Answer:

A. The Network A sample

Step-by-step explanation:

The variability of a dataset is a measure of how values in the dataset deviates from the mean value, the variability of a dataset is usually measured using the variance and standard deviation of the data values.

In statistics, variability is curbed by increasing the sample size of the data as larger values in the sample usually means that the sample mean will be close to the population mean. Hence, since network A has the highest number of Sampled voters, then Network A will likely have lesser variability than both Network B and C. Similarly, Network B will likely have lesser variability than Network C.

Network A: 3800 voters sampled

• Network B: 3500 voters sampled

• Network C: 3250 voters sampled

A.

Answer:

12

Step-by-step explanation:

So since the total was 26.95 subtract the base cost of the mug which is 8.95

26.95-8.95=18.00

Then since each refill is 1.50 divide by 1.50

18/1.50=12

Answer:x<12

Step-by-step explanation:

X<12

Answer:

A. x ≤ -2 or x > 3

Step-by-step explanation:

The number line shows two possible values of x which represents a compound inequality.

There are two arrows in opposite direction on the number line.

The arrow that starts at -2 and goes to your far left, has a shaded small circle "o". This connotes that -2 is included in the possible values of x. Thus, this means the possible value of x is equal to -2 or less than -2 ==> x ≤ -2.

The other arrow starts at 3 and has an unshaded small "o", implying that 3 is not included in the possible values of x. Thus, x > 3.

The compound inequality in the graph indicates either statement is true, since each solution do not overlap, hence, the word to use here would be "OR", showing a union.

Therefore, the solution of the compound inequality would be x ≤ -2 or x > 3.

Answer:

2 - 4x² + 15(3 + y)

Step-by-step explanation:

Given.

3 -7p²+11(4+n)

Required

Write similar expression:

The given expression can be split into:

3, -7p² and 11(4 + n)

3 can be replaced with 2 or any number (but let's stick with 2).

-7p² can be replaced with -4x²

Lastly,

11(4 + n) can be replaced with 15(3 + y)

Bringing them together, we have:

2 - 4x² + 15(3 + y)

So, an expression similar to 3 - 7p² + 11(4 + n) is 2 - 4x² + 15(3 + y)

Please note that, there are other similar expressions

Answer:

Answer:

x=10

Step-by-step explanation:

Answer:

x = - 5/3

Step-by-step explanation:

Calculate the product

4x/5 = 2x + 4/2

Reduce the faction with 2

4x/5 = 2x + 2

Multiply both sides of the equation by 5

4x = 10x + 10

Move variable to the left-hand side and change its sign

4x - 10x = 10

Collect like terms

-6x = 10

Divide both sides of the equation by -6

x = - 5/3

Solution

x = -5/3

Alternate form

x = -1 2/3, x = -1.6

Any rational number is in the form p/q, where p,q are integers and q is nonzero.

If we made q = 1, then p/q turns into an integer which is why the set of integers is inside the set of rational numbers.

For instance, if p = 7 and q = 1, then p/q = 7/1 = 7 is an integer and it is rational too.

Answer:

0.265

Step-by-step explanation:

Given that :

Number of flaws per mm follows a poisson distribution:

Mean flaws per mm (x) = 2.3

Probability of exactly two flaws in 1 mm of wire

P(X = 2) = (x² * e^-x) / x!

P(x = 2) = (2.3² * e^-2.3) / 2!

P(x = 2) = (5.29 * 0.1002588) / 2

P(x = 2) = 0.265

Answer:

x=1/2 or x=0.5

Step-by-step explanation:

14=18x+8 so 18x =6 so x=1/2

Answer:

x = 1/3

Step-by-step explanation:

14 = 18x + 8

Subtract 8 from both sides.

6 = 18x

Divide both sides by 18.

6/18 = x

Simplify.

1/3 = x

Option:

a. for every 13 dogs, there are 25 cats.

b. there are twice as many cats as dogs at the shelter.

c. the shelter has more dogs than cats.

d. there are 25 animals in the shelter.

Answer:

a. for every 13 dogs, there are 25 cats.

Step-by-step explanation:

Represent Dogs with D and Cats with C;

So;

[tex]\frac{D}{C} = \frac{13}{25}[/tex]

By comparison:

[tex]D=13[/tex]

[tex]C = 25[/tex]

This implies that:

For every 13 D, there are 25 C

Hence: Option A is true

Answer:

C.)$31,390

Step-by-step explanation:

You can use the formula to calculate the future value to find the answer:

FV=PV*(1+i)^n

FV= future value

PV= present value= 29,000

i= interest rate=2%

n= number of periods of time= 4

Now, you can replace the values in  the formula:

FV=29,000*(1+0.02)^4

FV=29,000*(1.02)^4

FV=31,390

According to this, the answer is that the annual rent would be $31,390 at the end of four years.

$62.50 because

Step-by-step explanation:

250÷4=62r2

62.50•4=250

Ms. Beg withdraw $62.5 from her account to pay for her services.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Ms. Berg wrote 4 equal checks totaling $250 to pay for her salon services.

to with

So, to withdraw from the account to pay for services each month

= 250/4

= 125/2

= 62.5

Hence, she withdraw $62.5 from her account to pay for her services.

Answer:

0.5818

Step-by-step explanation:

Suppose the average teenage romantic relationship is normally distributed with a mean number of 100 days with a standard deviation of 30 days.

Answer:

The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\where\ \mu=mean,\sigma=standard\ deviation, x=raw\ score[/tex]

Given that:

[tex]\mu=100\ days,\sigma=30\ days\\\\For\ x=90\\\\z=\frac{90-100}{30} =-0.33\\\\For\ x=150\\\\z=\frac{150-100}{30} =1.67[/tex]

Therefore, from the normal distribution table, P(90 < x < 150) = P(-0.33 < z < 1.67) = P(z < 1.67) - P(z < -0.33) = 0.9525 - 0.3707 = 0.5818
