how to construct 75°​

Answers

Answer 1

answer:

in order to construct 75°, you need to use a protractor and a compass

step-by-step explanation:

here is a step-by-step explanation from an online source

step 1: draw a line segment with endpoint O and Astep 2: draw an arc with O as centre cutting the line segment OA at point B with a compassstep 3: keeping the radius same, draw an arc with B as centre cutting the arc at Cstep 4: keeping the radius same, and C as the center, draw an arc intersecting the arc drawn in the previous step at Dstep 5: with any radius, draw two arcs with C and D as a center. intersect these two arcs at Estep 6: join OE. angle EOA is the angle with measurement of 90 degreesstep 7: now the line OE intersect the arc at the point Fstep 8: taking F and C as a center, make an arc with a radius of more than half of the measurement FC. the arc intersects at point Hstep 9: join the point H and O. angle HOA is the angle obtained of measurement 75 degreesstep 10: angle HOA is the desired angle
Answer 2

Construct 60°. Then 120°. Then construct 90° by bisecting them. Then bisect 60° and 90°. Then it will be 75°.

When Victoria goes bowling, her scores are normally distributed with a mean of 130 and a standard deviation of 11. What is the probability that the next game Victoria bowls, her score will be between 123 and 130, to the nearest thousandth?

Answers

Answer:

0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 130 and a standard deviation of 11.

This means that [tex]\mu = 130, \sigma = 11[/tex]

What is the probability that the next game Victoria bowls, her score will be between 123 and 130?

This is the p-value of Z when X = 130 subtracted by the p-value of Z when X = 123. So

X = 130

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

[tex]Z = \frac{130 - 130}{11}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a p-value of 0.5

X = 123

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

[tex]Z = \frac{123 - 130}{11}[/tex]

[tex]Z = -0.64[/tex]

[tex]Z = -0.64[/tex] has a p-value of 0.2611

0.5 - 0.261 = 0.239

0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130

Solve for line segment AB

Answers

Answer:

AB = 32

Step-by-step explanation:

Given:

AD = 40

CD = 9

Required:

Find the length of segment AB

Solution:

BC and CD are radius of the circle. Therefore,

BC = CD = 9

AB = AC - BC

AB = AC - 9

We need to find AC

Since AD is tangent, CD is perpendicular to AD, this means that <D is a right angle. This makes ∆ADC a right triangle.

Therefore, we can apply Pythagorean theorem to find AC.

Thus:

AC² = AD² + CD²

AC² = 40² + 9²

AC² = 1,681

AC = √1,681

AC = 41

Let's find BC:

AB = AC - 9

Plug in the value of AC

AB = 41 - 9

AB = 32

Answers

Given:

The table of values of function [tex]y=f(x)[/tex] is given.

To find:

The table of values of function [tex]y=f(\dfrac{1}{5}x)[/tex].

Solution:

The horizontal stretch is defined as:

[tex]g(x)=f(ax), 0<a<1[/tex]

Here, f(x) is horizontally stretched by factor a to get g(x).

The given function is:

[tex]y=f(\dfrac{1}{5}x)[/tex]

It means the function [tex]y=f(x)[/tex] is horizontally stretched by factor [tex]\dfrac{1}{5}[/tex] to get [tex]y=f(\dfrac{1}{5}x)[/tex].

So, we need to multiply the given x-values by 5 to get the required table of values.

Therefore, the required table of values is:

what is the area of a square with its side length of s cm

Answers

Answer:

Step-by-step explanation:

Answer:

The area is s².

Step-by-step explanation:

The area of a square is the length times the width. Because it's a square, the length and width are the same, so instead of multiplying the length and width, we can take the length of one side and square it. You said the length is "s", which I assume is a variable, so the area will equal s ⋅ s, or s².
