Answers:
x = 7*sqrt(3)
y = 7
===========================================================
Explanation:
We have a 30-60-90 triangle here since the missing acute angle is 90-60 = 30 degrees. Or you could note how 30+60+90 = 180.
The side length y is the shorter leg as it's opposite the smallest angle. It's equal to half of the hypotenuse. So y = 14/2 = 7.
The longer leg x is equal to y*sqrt(3). We multiply the shorter leg by sqrt(3) to get the longer leg. This means
x = y*sqrt(3) = 7*sqrt(3)
----------
You could also use the pythagorean theorem if you knew that y = 7 and you had the hypotenuse value as well. You could solve like so
a^2 + b^2 = c^2
7^2 + b^2 = 14^2
b^2 = 14^2 - 7^2
b^2 = 147
b = sqrt(147)
b = sqrt(49*3)
b = sqrt(49)*sqrt(3)
b = 7*sqrt(3)
Which matches up with the value of x we found earlier.
State whether each situation has independent or paired (dependent) samples. a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination. b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without
Answer:
a. A researcher wants to compare the hand–eye coordination of men and women. She finds a random sample of 100 men and 100 women, and measures their hand–eye coordination = paired samples
b. A researcher wants to know whether professors with tenure have fewer office hours than professors without tenure. She observes the number of office hours for professors with and without tenure. = independent samples
Explanation:
Paired-samples t tests compare scores on two different variables but for the same group of cases; independent-samples t tests compare scores on the same variable but for two different groups of cases.

An angle measured 140 more than the measure of its supplementary angle. What is the measure of each angle ?
Answer:
Supplementary angle equals 180°
Complementary angle equals 360°
Step-by-step explanation:
Conjugate angles are more or less related to complementary and supplementary angles. The sum of the two angles put together equals 360 degrees. The last angle that will be named is straight. The measure of the angle equals 180 degrees.

class has a sister?
Answer: 5/30 chance of it happening
Step-by-step explanation:
The probability is 5/30 chance of it happening.
We have given that,
In a class of students, the following data table summarizes how many students have a brother or a sister.
We have to determine the probability that a student chosen randomly from the class has a sister.
What is the formula for probability?The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
Therefore the probability is 5/30 chance of it happening.

Suppose y varies directly as x. If y = 12 when x = 4:
Write the general variation equation
Find the constant of variation, k.
Write a variation equation relating x and y using the value of k found in b).
Find y when x = -5.
у
Answer:
y = -15
Step-by-step explanation:
Given that,
y varies directly as x i.e.
[tex]y\propto x\\\\y=kx[/tex]
Where
k is the constant of variation.
Put y = 12 and x = 4 to find k.
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{12}{4}\\\\k=3[/tex]
Now put k = 3 and x = -5 and finding the value of y.
[tex]y=3\times -5\\\\y=-15[/tex]
So, the value of y is equal to -15.

Answer:
a_3=4
Step-by-step explanation:
a1 = 100
r = 1/5
an = 100 (1/5)^(n - 1)
so we now have the answer for a_3
a_3 = 100 * (1/5)^(3 - 1)
a_3 = 100 * (1/5)^2
a_3 = 100 * 1/25

find the volume of this cylinder. round to the nearest tenth
Answer:3418
Step-by-step explanation:
The volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.
To find the volume of a cylinder, you can use the formula:
Volume = π * r² * h
Given:
Radius (r) = 8 ft
Height (h) = 17 ft
Plugging these values into the formula, we can calculate the volume:
Volume = π * (8 ft)² * 17 ft
= π * 64 ft² * 17 ft
≈ 3418.05 ft³
Rounding the volume to the nearest tenth, we get:
Volume ≈ 3418.1 ft³
Therefore, the volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.
