Answers

Answer:

h = 65, g = 115, m = 49, k = 131

Step-by-step explanation:

h and 115 are supplementary angles, so 180 - 115 is 65 degrees.

g and 115 are vertical angles, so both should be 115 degrees.

m and 131 are supplementary angles, so 180 - 131 = 49 degrees.

k and 131 are vertical angles, so both should be 131 degrees.

a-2. What is the calculated F value for comparing the standard deviation?
b. Are the two standard deviations for the locations significantly different at the 95% confidence level?
A. yes.
B. No.
c. What is the calculated t value used to compare the means of these two locations?
d. Are the means for the two different locations significantly different at the 95% confidence level?
A. yes.
B. No.

2 10.20 104.04 10.90 118.81

3 10.30 106.09 10.20 104.04

4 10.40 108.16 10.70 114.49

5 10.20 104.04 10.40 108.16

∑ 51.5 530.49 52.3 547.51

x`= ∑x/n1 = 51.5/5= 10.3; y`= ∑y/n2= 52.3/5= 10.46

Sx² = 1/n1-1[ ∑x² - (∑x)²/n1] = 1/4[ 530.49 - (51.5)²/5]

= 1/4[ 530.49 - 530.45] = 0.01

Sy² = 1/n2-1[ ∑y² - (∑y)²/n2] = 1/4[ 547.51 - (52.3)²/5]

= 1/4[ 547.51 - 547.058] = 0.113

F= Sx²/Sy²= 0.01/0.113= 0.08849

The critical region is F ≥ F(0.025) (5,5)= 7.15

and F ≤ 1/F(0.025) (5,5) = 1/7.15= 0.13986

Since the calculated value of F =0.08849 falls in the critical region we conclude that the two standard deviations for the locations significantly different at the 95% confidence level.

c. t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

t= 10.3-10.46/ sqrt( 0.01/5 +0.113/5)

t=- 0.16/0.15684

t= -1.020

d. The calculated value t= -1.020 does not fall in the the critical region

t (0.025) (4) = ±2.776 we conclude that the means for the two different locations are not significantly different at the 95% confidence level.

he needs to determine the measure of the kite?

The measure of angle A is 86.

What is a kite?

A kite is a flying object that is tethered to the ground by a string or a cord. It typically has a light framework of bamboo, plastic, or other materials, covered with paper or fabric, and often in the shape of a diamond or triangle.

We have,

From the figure,

We see that,

6x + 4 + ∠A = 180

Now,

∠A = 4x + 26

So,

6x + 4 + 4x + 26 = 180

10x + 30 = 180

10x = 180 - 30

10x = 150

x = 15

Now,

∠A = 4x + 26 = 4 x 15 + 26 = 60 + 26 = 86

Thus,

The measure of angle A is 86.

The area (in square inches) of a rectangle is given by the polynomial function A(p) = p2 + 9p + 20. If the length of the rectangle is (p + 5) inches, what is the width?

Answers

Answer:

[tex]Width = p + 4[/tex]

Step-by-step explanation:

Given

[tex]Area = p^2 + 9p + 20[/tex]

[tex]Length = p + 5[/tex]

Required

Determine the width

The area of a rectangle is:

[tex]Area = Length * Width[/tex]

This gives:

[tex]p^2 + 9p + 20= (p+5)* Width[/tex]

Expand

[tex]p^2 + 4p + 5p + 20= (p+5)* Width[/tex]

Factorize

[tex]p(p + 4) + 5(p + 4)= (p+5)* Width[/tex]

[tex](p + 5) (p + 4)= (p+5)* Width[/tex]

Divide both sides by p + 5

[tex]p + 4= Width[/tex]

[tex]Width = p + 4[/tex]

JL=5x+7

JL=5×(5)+7

JL=32

The side ST is obtained

ST=(1/2)×JL

ST= 1/2 of 32

ST = 16

Hence, the length of midsegment ST will be 16.

Find the volume of the cone in terms of pi. A cone with a radius of 5 feet and a height of 12 feet.

Answers

Answer:

V = [tex]\pi[/tex]r^2 x height

Step-by-step explanation:

Question:-

Find the volume of the cone in terms of π. A cone with a radius of 5 feet and a height of 12 feet.

Answer:-

Given:-

Radius (r) of the cone = 5 feet.

Height (h) of the cone = 12 feet.

To Find:-

The volume of the cone.

Solution:-

We know,

Formula of Volume of Cone is [tex] \frac{1}{3} [/tex]πr²h

Volume of the cone = [tex] \frac{1}{3} [/tex]× π × (5)² × 12

Volume of the cone = [tex] \frac{1}{3} [/tex]× π × 5 × 5 × 12

Volume of the cone = [tex] \frac{\pi \: × \: 5 \: × \: 5 \: × \: 12}{3} [/tex]

Volume of the cone = [tex] \frac{300\pi}{3} [/tex]

Volume of the cone = 100π in³

Volume of the cone is 100π in³.

Hence, option (d) 100π in³ is correct. [Answer]
