We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90  10,20,30,40,50,60,70,80,90.

A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the scores of a random sample of 238 graduating seniors and found the mean score to be 493 with a standard deviation of 97. Calculate the margin of error using the given formula. How could the results of the survey be made more accurate?

Answers

Answer:

±12.323

Step-by-step explanation:

A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the scores of a random sample of 238 graduating seniors and found the mean score to be 493 with a standard deviation of 97. Calculate the margin of error using the given formula. How could the results of the survey be made more accurate?

The formula for margin of Error =

±z × Standard deviation/√n

We are not given the confidence interval but let us assume the confidence interval = 95%

Hence:

z score for 95% confidence interval = 1.96

Standard deviation = 97

n = random number of samples = 238

Margin of Error = ± 1.96 × 97/√238

Margin of Error = ±12.323

The margin of error using the given formula will be ±12.323.

What is the error?

An error is a mistaken or erroneous action. In some contexts, an error is interchangeable with a mistake.

The discrepancy between the calculated value and the correct value is referred to as an "error" in statistics.

Given data;

Confidence interval = 95%

z score for 95% confidence interval = 1.96

Standard deviation = 97

n is a random number of samples = 238

The margin of Error is found as;

E =±z × Standard deviation/√n

[tex]\rm E= +z \times \frac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm E=\±1.96 \times \frac{97}{\sqrt{238} }\\\\ E=\±12.323 \[/tex]

Hence,the margin of error using the given formula will be ±12.323.

Step-by-step explanation:

Lateral Surface Area of a Cone

Given a right circular cone of base radius r and height h, the lateral surface area is given by:

[tex]A=\pi r\sqrt{r^2+h^2}[/tex]

We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.

Squaring:

[tex]A^2=\pi^2 r^2(r^2+h^2)[/tex]

Dividing by [tex]\pi r^2[/tex]

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2[/tex]

Subtracting [tex]r^2[/tex]:

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2[/tex]

Taking square root:

[tex]\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}[/tex]

Substituting the values:

[tex]\displaystyle h=\sqrt{ 251.472-22.5625}[/tex]

[tex]\displaystyle h=\sqrt{ 228.909}[/tex]

h = 15.13 cm

Answers

Step-by-step explanation:

8x + 13y = 75 (×10)

10x + 9y = 72 (×8)

80x + 130y = 750

-) 80x + 72y = 576

58y = 174

y = 3

10x + 9(3) = 72

10x + 27 = 72

10x = 72 - 27

10x = 45

x = 4.5

Select all true statements.
A) Dilation's of an angle must be congruent to the original angle.
B) Dilation's if a triangle must be congruent to the original triangle.
C) Dilation's of a segment must be congruent to the original segment.
D) Dilation's of a circle must be congruent to the original circle.

Answers

Answer:

A) Dilation's of an angle must be congruent to the original angle.

B) Dilation's if a triangle must be congruent to the original triangle.

Step-by-step explanation:

Dilation is one of rigid transformations in which the size of an angle or object is either increased or decreased, to produce an image, with respect to a given factor. In this process, the dimensions of the object are affected but its orientation remains the same.

When a figure is dilated, the new figure is congruent to the original figure. Also, when an angle undergoes dilation, its measure is not affected. Thus, it would be congruent to the original angle.

write the equation of the line in slope- intercept and point-slope form.​

Answers

Answer:

Step-by-step explanation:

As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise).  Thus, the slope of this line is

m = rise/run = 4/2 = 2.

Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.

From this we get the point-slope form:

y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.

WILL GIVE BRAINLIEST ! A marble is picked at random.Without putting the first marble back,a second marble is picked at random find the probability that the fist marble picked is green and the second marble is picked red write your result as a percentage

Answers

Step-by-step explanation:

The percentage is 1/2 * 2/5 = 1/5 = 20%.

The probability that the first marble picked is green, and the second marble is picked red is 20%

What is probability?

A probability is a number that reflects the chance or likelihood that a particular event will occur.

Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Given that, there are six marbles in total, 3 are green, 2 are red and one is brown,

we need to find the probability that the first marble picked is green, and the second marble is picked red,

So, P(E) = favorable outcome / total outcome

Therefore, the probability that the first marble picked is green, and the second marble is picked red = 3/6 x 2/5 = 6/30 = 1/5 = 20%

Hence, the probability that the first marble picked is green, and the second marble is picked red is 20%

Declan wants to mail 28 drawings to his Grandma. If he can fit 3 drawings in each envelope, how many envelopes will he need to mail all the drawings

Answers

Answer: 10 envelopes

Explanation: 28÷3=9.33
Now, I am assuming you can't have 9 1/3 envelopes, so I rounded up (which makes the answer 10).

Answer:

10 envelopes

Step-by-step explanation:

What we know:

- There are 3 drawings for each envelope

- There are 28 drawings in total

To find out the number of envelopes Declan would need, we divide 28 by 3 (check the picture attached).

28÷3=9 R1

28 divided by 3 gives us 9 with a remainder of 1, which means if Declan had 9 envelopes, he would be able to fit 3 drawings in each with 1 drawing left over. He would need a 10th envelope to use for the last drawing.

Therefore, Declan would need 10 envelopes to mail all the drawings to his grandma.

For her birthday, Samantha received a gift card, with a value of $200, to a department store. She wants to purchase at least 5 articles of clothing for work. At the store, sweaters cost $22.49 each and dress pants cost $34.99 each. If Samantha does not spend more than the amount on the gift card, which system of inequalities could be used to determine the number of sweaters, s, and the number of dress pants, p, she can buy?

Answers

Answer:

The system of inequalities are;

p + s ≥ 5

22.49s + 34.99p ≤ 200

Where P represents number of dress pants and s represents the number of sweaters

Step-by-step explanation:

Here, we want to write system of inequalities

Let the number of sweaters be s and the number of pants be p

She wants to purchase at least 5 items

When we have at least, it means that it might be greater than or equal to that value

Thus;

p + s ≥ 5

Secondly, at most the amount to be spent is the value on the gift card which is 200

Thus;

we have;

22.49s + 34.99d ≤ 200

Henry drank 2/5 of his water bottle. If he drank 3 cups of water, what was the total amount of cups of water in his water bottle? Solve with a model and a full sentence answer.

Answers

Answer:

The amount of cups of water in the water bottle is 7.5.

Step-by-step explanation:

Given that Henry drank 2/5 of his bottle of water, and those 2/5 were distributed in 3 glasses, to determine the total amount of glasses that go into the bottle it is necessary to perform the following calculation:

2/5 X = 3

1/5 X = 1.5

X = 1.5 x 5

X = 7.5

Therefore, the bottle fits 7 and a half glasses of water.
