Answer:

5/16 mile

Step-by-step explanation:

5/8 * 1/2 = 5/16 mile

Answer:

Below!

Step-by-step explanation:

Given square root:

[tex]\sqrt41[/tex]

Let's note a few perfect square roots.

[tex]1 = \sqrt{1 \times 1} = \sqrt{1}[/tex]

[tex]2 = \sqrt{2 \times 2} = \sqrt{4}[/tex]

[tex]3 = \sqrt{3 \times 3} =\sqrt{9}[/tex]

[tex]4 = \sqrt{4 \times 4} =\sqrt{16}[/tex]

[tex]5 = \sqrt{5 \times 5} =\sqrt{25}[/tex]

[tex]6 = \sqrt{6 \times 6} =\sqrt{36}[/tex]

[tex]7 = \sqrt{7 \times 7} =\sqrt{49}[/tex]

[tex]8 = \sqrt{8 \times 8} =\sqrt{64}[/tex]

And so on...

When looking at the perfect square roots we identified, we can say that:

[tex]\sqrt{36} < \sqrt{41} < \sqrt{49}[/tex]

Therefore,

[tex]6 < \sqrt{41} < 7[/tex]

We can conclude that [tex]\sqrt{41}[/tex] is between 6 and 7.

Let's check the squares of first 10 number

41 lies between 36 and 49

Answer:

B. The sample proportion would less closely model the population proportion.

Step-by-step explanation:

if they chose 10% and changed it to 5% theres gonna be less data to go by.

The sample proportion would less closely model the population proportion.

Option A is the correct answer.

Random sampling is a statistical method of selecting a sample from a larger population in a way that every individual in the population has an equal chance of being selected.

In other words, random sampling is a process of selecting a subset of individuals from a population in which every member of the population has an equal chance of being chosen.

This helps to reduce bias and increase the likelihood that the sample represents the population accurately.

Random sampling is commonly used in research studies, opinion polls, and market research to draw conclusions about a population based on a smaller sample.

We have,

When the sample size is smaller, there is a higher chance of the sample being unrepresentative of the population, resulting in a larger sampling error.

Therefore, if the student council decided to sample only 5% of the student body instead of 10%, it is more likely that the sample proportion would be less accurate and less closely model the population proportion.

Thus,

The sample proportion would less closely model the population proportion.

Answer:

38.4895

Step-by-step explanation:

area of circle = pi * r^2

3.142 * 7^2 = area of the whole circle

as we only have 1/4 of the circle we divide our area by 4

(3.142 *7^2) / 4 = 38.4895

Answer:

38.4895

Step-by-step explanation:

basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2

so that's 3.142×7^2 and then divided by 4.

Answer:

10

Step-by-step explanation:

The quadratic equation has no real roots. This means the line and point has no point of intersection.

System of equations are equations that is more than one and have two or more unknowns.

Given the simultaneous equation

x^2 + y^2 = 25

2x + y = 25

from equation 2;

y = 25 - 2x ................3

Substitute equation 3 into 1 to have:

x^2 + (25-2x)^2 = 25

x^2 + 625 - 100x + 4x^2 = 25

5x^2 -100x + 600 = 0

x^2 -20x + 120= 0

Hence the quadratic equation has no real roots. This means the line and point has no point of intersection,

(0,-5) and (-4,3)

Answer:

A, B, D, E

Step-by-step explanation:

Every point is on the circle except for the middle one

The points lying on the circle will be (-4, 12), (-6, 6), and (4, 16). Then the correct options are A, B, and E.

Let r be the radius of the circle and the location of the center of the circle be (h, k). Then the equation of the circle is given as,

(x - h)² + (y - k)² = r²

The center is at (4, 6) and the radius is 10 units. Then the equation of the circle is calculated as,

(x - 4)² + (y - 6)² = 10²

(x - 4)² + (y - 6)² = 100             .......1

Substitute (-4, 12) in equation 1, then we have

(-4 - 4)² + (12 - 6)² = 100

100 = 100

Substitute (-6, 6) in equation 1, then we have

(-6 - 4)² + (6 - 6)² = 100

100 = 100

Substitute (13, 10) in equation 1, then we have

(13 - 4)² + (10 - 6)² = 100

97 ≠ 100

Substitute (-4, 12) in equation 1, then we have

(4 - 4)² + (16 - 6)² = 100

100 = 100

If the equation is satisfied, then the point lies on the circle.

If the mean of the sample is 18.7, The 95% confidence interval for the population mean is 18.7 ± 11.6.

z-score for 95% confidence interval =1.96

Lower limit of the interval:

Lower limit=Sample mean-(Z-score×Margin of error)

Lower limit=18.7-(1.96×5.9)

Lower limit=18.7-11.564

Lower limit=18.7-11.6 (Approximately)

Upper limit of the interval:

Upper limit=Sample mean+(Z-score×Margin of error)

Upper  limit=18.7+(1.96×5.9)

Answer:

[tex] \: [/tex]

Step-by-step explanation:

Let us assume A, B, C and D are the four angles of the parallelogram. Where, ∠A = 20° and we have to find the measure of ∠B, ∠C and ∠D

So, If ∠A = 20°, then So, also ∠C = 20°.

Therefore,

⠀

And, ∠A and ∠B are adjacent angles. We know,

So,

⇒ ∠A + ∠B = 180°

⇒ 20° + ∠B = 180°

⇒ ∠B = 180° – 20°

⇒ ∠B = 160°

So,

⠀

So, If ∠B = 160°, then So, also ∠D = 160°.

Remark

The angle opposite the hypotenuse is 90 degrees. The hypotenuse is 13 in this case and is labeled c.

The second longest line is opposite the second largest angle

Sin(A) = opposite / hypotenuse

Solution

Sin(A) = 12 / 13   =        Opposite / hypotentenuse

Sin(A) = 0.9231             12/13 = 0.9231          

A = sin-1(0.9231)           Take the inverse sine of 0.9231

A = 67 rounded

Therefore then angle opposite the shortest side must be 90 - 67 = 23
