find the distance from the origin to the graph of 6x+3y+2=0

Answer:

No

Step-by-step explanation:Because there is not degree higher than one in the equation. Therefore it is linear.

Answer:

1) [tex]z=\frac{0.07 -0.06}{\sqrt{\frac{0.06(1-0.06)}{300}}}=0.729[/tex]  

We can calculate the p value with the following formula:

[tex]p_v =2*P(z>0.729)=0.466[/tex]  

The p value for this case is very high and using the significance level of 0.01 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the statment makes sense.

2) [tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex]   (b)  

And replacing into equation (b) the values from part a we got:

[tex]n=\frac{0.06(1-0.06)}{(\frac{0.01}{1.96})^2}=2166.66[/tex]  

And rounded up we have that n=2167

Step-by-step explanation:

Information given

n=300 represent the random sample taken

X=21 represent the number of peanuts empty  

[tex]\hat p=\frac{21}{300}=0.07[/tex] estimated proportion of peanust empty

[tex]p_o=0.06[/tex] is the value to test

[tex]\alpha=0.05[/tex] represent the significance level

z would represent the statistic

[tex]p_v[/tex] represent the p value

Part 1

We want to test if the true proportion is 6% or no the system of hypothesis are:  

Null hypothesis:[tex]p=0.06[/tex]  

Alternative hypothesis:[tex]p \neq 0.06[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Replacing the info given we got:

[tex]z=\frac{0.07 -0.06}{\sqrt{\frac{0.06(1-0.06)}{300}}}=0.729[/tex]  

We can calculate the p value with the following formula:

[tex]p_v =2*P(z>0.729)=0.466[/tex]  

The p value for this case is very high and using the significance level of 0.01 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the statment makes sense.

Part 2

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]    (a)  

And on this case we have that [tex]ME =\pm 0.01[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex]   (b)  

And replacing into equation (b) the values from part a we got:

[tex]n=\frac{0.06(1-0.06)}{(\frac{0.01}{1.96})^2}=2166.66[/tex]  

And rounded up we have that n=2167

Joseph : y = 25x + 15

Molly: y = 25x + 25

Joseph: y = 25(4)+ 15= 100+ 15= 115

Molly: y = 25(4)+ 25= 100+25= 125

Answer:

I hope this helps! <:

Step-by-step explanation:

The start is 15 and 25 so you keep on adding 25 to each of them, let's start with 15, 15+25=40 and 40 plus 25 is 65 and 65+25 is 90 the last one is 90+25= 115, now let's move on to 25. 25+25= 50 and the next one is 50+25=75 and then 75+25=100 and 100+25= 125.

Answer:

6x + y = 38.75

x + 2y = 17

price of drink is $5.75

Step-by-step explanation:

Let the price  of popcorn be x

Let the price  of drink be y.

price  of  12 bags of popcorn will be 12x

price  of  2 drinks  will be 2y

it is given that "Kennedy spends a total of $77.50 on 12 bags of popcorn and 2 drinks."

thus

12x + 2y = 77.50

dividing LHS and RHS by 2 we have

12x/2 + 2y/2 = 77.50/2

=> 6x + y = 38.75 _________(1)

__________________________________________________

price  of  3 bags of popcorn will be 3x

price  of  6 drinks  will be 6y

it is given that "Olivia spends a total of $51.00 on 3 bags of popcorn and 6 drinks."

thus

3x + 6y = 51.00

dividing LHS and RHS by 3 we have

3x/3 + 6y/3 = 51/3

=> x + 2y = 17   _____________(2)

__________________________________________________

Thus we have two equation

6x + y = 38.75 _________(1)

x + 2y = 17

=> x = 17 - 2y

putting this value of x in equation 1 we have

6( 17 - 2y) + y = 38.75

=> 102 - 12y + y = 38.75

=> 102 - 11y = 38.75

=> -11y = 38.75 -102

=> -11y = -63.25

=> y = -63.25/-11 = 5.75

as we have x = 17 - 2y

using 5.75 in place of y

x = 17 - 2(5.75 )

=> x = 17 - 11.5

=> x = 5.5

Thus, system of equations are

6x + y = 38.75

x + 2y = 17

price of drink is $5.75

Step-by-step explanation:

One afternoon, they each had 2 large  chocolate bars.

Amy 8/6  of her chocolate bar = (2 - 8/6) = 2/3

Bill 1 1/6 of his chocolate bars = (2 - 11/6 = 2 - 7/6 = 5/6)

Katie 9/6 of her chocolate bars  = (2-9/6) = 1/2

Gretchen 1 5/6 of her chocolate bars  = (2- 1 5/6) = 2 - 11/6 = 1/6

Dylan 1 3/6 of his chocolate bars = 2 - 1 3/6 = 2-9/6 = 1/2

Answer:

k=4

Step-by-step explanation:

y=3(1)-1

y=2

2=-2x+k

2=-2(1)+k

2=-2+k

4=k

Answer:

k = 4

Step-by-step explanation:

y = 3x -1

y = -2x+k

Set the two equations equal

3x -1 = -2x+k

Combine like terms

Add 2x to each side

3x+2x -1 =-2x+2x +k

5x - 1 = k

We know they are equal when x= 1

Let x=1

5*1 -1= k

5 -1= k

4 = k

Answer:

Null hypothesis:[tex]p\leq 0.3[/tex]  

Alternative hypothesis:[tex]p > 0.3[/tex]  

Critical value: [tex] z_{\alpha/2}= 1.64[/tex]

Test statistic: [tex]z=\frac{0.462 -0.3}{\sqrt{\frac{0.3(1-0.3)}{65}}}=2.85[/tex]  

For this case the calculated value is higher than the critical value so then we can reject the null hypothesis. And we can conclude that the true proportion of cars with emissions systems which failed to meet pollution control guidelines for this case is significantly higher than 0.30 or 30%

Step-by-step explanation:

Information given

n=65 represent the random sample taken

X=30 represent the number of cars with emissions systems which failed to meet pollution control guidelines

[tex]\hat p=\frac{30}{65}=0.462[/tex] estimated proportion of cars with emissions systems which failed to meet pollution control guidelines

[tex]p_o=0.30[/tex] is the value to verify

[tex]\alpha=0.05[/tex] represent the significance level

z would represent the statistic

[tex]p_v[/tex] represent the p value

Hypothesis to test

We want to verify if the true proportion for this case is higher than 0.3 or no, the system of hypothesis are:  

Null hypothesis:[tex]p\leq 0.3[/tex]  

Alternative hypothesis:[tex]p > 0.3[/tex]  

The statistic for this case would be:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Replacing the info we got:

[tex]z=\frac{0.462 -0.3}{\sqrt{\frac{0.3(1-0.3)}{65}}}=2.85[/tex]  

The critical value for this case would be taking in count the significance level in the right tail:

[tex] z_{\alpha/2}= 1.64[/tex]

For this case the calculated value is higher than the critical value so then we can reject the null hypothesis. And we can conclude that the true proportion of cars with emissions systems which failed to meet pollution control guidelines for this case is significantly higher than 0.30 or 30%

Answer:

[tex]\dfrac{3}{2}[/tex]

Step-by-step explanation:

We are given 2 fractions.

1st fraction is Negative StartFraction 3 over 8

i.e.

[tex]-\dfrac{3}{8}[/tex]

2nd fraction is negative one-fourth

i.e.

[tex]-\dfrac{1}{4}[/tex]

We have to find the quotient when 1st fraction is divided by 2nd fraction.

Definition of quotient is given as:

Quotient is the result obtained when one number is divided by other number.

[tex]-\dfrac{3}{8} \div -\dfrac{1}{4} \text{ is to be calculated.}[/tex]

[tex]\div[/tex] is converted to [tex]\times[/tex] and the 2nd fraction is reversed i.e.

if the fraction is [tex]\frac{p}{q}[/tex] it becomes [tex]\frac{q}{p}[/tex] and the sign [tex]\div[/tex] is changed to [tex]\times[/tex].

Solving above:

[tex]-\dfrac{3}{8} \times -\dfrac{4}{1}\\ \text {Multiplication/Division of 2 negative number gives a positive number}\\\Rightarrow \dfrac{3}{2}[/tex]

So, the quotient is [tex]\frac{3}{2}[/tex].

Answer:

79.2° (First Option)

Step-by-step explanation:

To find mAB, recognize that the percents given for the pie chart can represent the percent area of the sector of the circle, the percent measure of the central angle that forms the sector, or the percent measure of the length of the arc.

The measure of an arc is equal to the measure of the central angle between the radii that form its endpoints. So, mAB=m∠AOB.

The measure of the central angle AOB that forms AB is 22 percent of the whole circle, or (0.22)360∘. So, mAB=0.22(360∘)=79.2∘

Therefore, the measure of arc AB

is 79.2∘.

The measure of the arc AB of a circle showing the different vitamins present in a health drink is 79.2 degrees.

The measure of an arc is always equivalent to the measure of the central angle between the radii that form its endpoints.

As the measure of an arc is always equivalent to the measure of the central angle between the radii that form its endpoints.

Thus [tex]m\angle{AOB}=\widehat{AB}[/tex].

First, find the measure of angle AOB.

Since the measure of angle AOB shows 22% of vitamins of the whole circle.

This means that the measure of angle AOB is 22% of 360 degrees.

Then we will get

[tex]m\angle{AOB}=\dfrac{22}{100}\times 360^{\circ}\\m\angle{AOB}=79.2^{\circ}[/tex]

Here the measure of angle AOB  is 79.2 degrees.

And since [tex]m\angle{AOB}=\widehat{AB}[/tex].

Therefore the measure of arc AB is 79.2 degrees.

That means option A [tex]79.2^{\circ}[/tex] is correct option.

Answer:

The area of the remaining board is [(L × B) - (l × b)].

Step-by-step explanation:

Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.

Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.

The area of any rectangle is:

Area = Length × Breadth

The area of the bigger rectangle is:

Area of ABCD = L × B

The area of the smaller rectangle is:

Area of PQRS = l × b

Then the area of the remaining board will be:

Area of remaining board = Area of ABCD - Area of PQRS

                                         = (L × B) - (l × b)

Thus, the area of the remaining board is [(L × B) - (l × b)].

Answer:

no solution

Step-by-step explanation:

Modular equation:

The modular of a function f(x)(|f(x)|) is the distance of f(x) to the origin.

In the case of a point, the modulus of the point is the distance to the origin.

If we have:

|f(x)| = a, it means that:

f(x) = a or f(x) = -a.

However

It is only true for non-negative values of a, since the modulus is a distance, which is a positive measure.

|–x| = –10

The modular is never a negative number, so it cannot be -10.

This means that there is no solution.

Option A. Base of the triangle is 3unita

Option B. Height of the triangle is 5units

Option B. Area of the triangle is 7.5units

Step-by-step explanation:

The question is incomplete and lacking appropriate diagram. Here is the complete question.

The base (b) of the triangle is _ units.

A) 3 B) 5 C) 8 D) 13

The height (h) of the triangle is units.

A) 3 B) 5 C) 8 D) 13

The area of the triangle is square units.

A) 5 B) 7.5 C) 15 D) 30

Also find the attachment below.

From the graph, each square box in the graph will be taken as 1unit.

Since the base of the triangle is sitting on 3-square boxes, the total units of its base will be 3units. The base of the triangle is therefore 3units.

Similarly, the height of the triangle covers 5 square boxes, therefore the height of the triangle will be 5units.

Area of the triangle = 1/2 × base × height

Area of the triangle = 1/2 × 3 × 5

Area of he triangle = 15/2 = 7.5units

a) 12 m² + 35

b) 15 m + 35 cm

d) 15 m + 35

3.- A child made four plasticine figures: two quadrangular prisms and two cylinders. In which figure did you occupy the most amount of modeling clay? JUSTIFY YOUR ANSWER

Solution

2) The area of a rectangle is given as

Area = Length × Breadth

Area = (120m² + 280m)

Length = f

Breadth = 8m

(120m² + 280m) = f × 8m

f = (120m² + 280m)/(8m)

f = (15m + 35)

Option D is correct.

f = (15m + 35)

3) For the second question, the images for the question and the dimensions of the figures aren't provided, hence, a very accurate answer can be provided. But without This, we can only speculate.

The figure that would use the most clay is the figure whose volume is the highest if the volumes of each of the figures are calculated.

Volume of a quadrangular prism = (Area of base) × (perpendicular height)

Volume of a cylinder = (Area of base) × (Height) = (πR² × H) = πR²H

So, it is in the evaluation of these volumes that the solution of this question is obtained.
