Answer:
Lower average yearly temperature because the cities receive insulation at a lower angle during the year
Step-by-step explanation:
As with increase in latitude there is a decrease of temperatures. Thus the region at higher altitude or latitudes sun rays are oblique and not direct.
Hence the cities like the Moscow, and Washington DC don't get vertical rays as compared to Kolkata, and Singapore in the south east as they lie near to the equator.Hence e the option 1 is correct.

ms. scott will pay $2,000 to have her house painted. the amount each painter earns, A, varies inversely for the number of painters, n, that will paint the house. which equation best represents this situation? A = 2,000 + n 2,000 = A + n A = 2,000n 2,000 = An
The equation that best represents the inverse variation between A and n is: D. 2,000 = An
What is an Inverse Variation?The equation that models an inverse variation between two variables, x and y, is: k = xy, where k is a constant value.
Given the following:
k = #2,000x and y are A and n respectively.Substitute the values into k = xy:
2,000 = An
The equation is: 2,000 = An

A consumer advocacy group wants to determine whether there is a difference between the proportions of the two leading automobile models that need major repairs (more than $500) within two years of their purchase. A sample of 400 two-year owners of model 1 is contacted, and a sample of 500 two-year owners of model 2 is contacted. The numbers x1 and x2 of owners who report that their cars needed major repairs within the first two years are 53 and 78, respectively. What is the p-value of the appropriate test of hypotheses
Answer:
The answer is "0.3206".
Step-by-step explanation:
[tex]H_0: p_1 = p_2\\\\H_a: p_1 \neq p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456[/tex]
Testing statistic:
[tex]z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}[/tex]
[tex]=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99[/tex]

6. Let the function g be defined by g(x) = x4 – x3 – 9x2 + 9x. It is given that
x = 1 is a zero of the function g. Which of the following best represents the fully
factored form of the function g?
Answer:
A
Step-by-step explanation:
There is an x in all for terms that means that x = 0 is one of the factors and H is incorrect.
One of the remaining factors is x^2 - 9 which factors into (x - 3)(x + 3)
You are told that x = 1 is a zero which means x - 1 is a factor.
The answer is g(x) = x (x - 3)(x + 3) (x - 1) which is A

Find the value of x.A.66B.58C.68D.32
Answer:
x = 66
Step-by-step explanation:
Remark
98 is an exterior angle. Exterior angles are the sum of the two remote interior angles. The remote interior angles have 2 properties
They are not supplementary to the exterior angleThey each share a side with the remote interior angle.It's much easier just to make an equation.
x + 32 = 98 Subtract 32 from each side
- 32 -32
x = 66

Which correctly describes a cross section of the square pyramid? Select three options. A square pyramid with 2 foot sides. A cross section parallel to the base is a square with side lengths of 2 ft. A cross section parallel to the base is a square with side lengths of less than 2 ft. A cross section perpendicular to the base through the top vertex is a triangle with the same dimensions as the triangular sides of the pyramid. A cross section perpendicular to the base through the top vertex is a triangle with different dimensions than the triangular sides of the pyramid. A cross section that is perpendicular to the base that does not pass through the top vertex of the pyramid is a trapezoid.
Answer:
A cross section parallel to the base is a square with side lengths of less than 2 ft.

The square of p varies inversely as q. When Q=6 p=4
What is the value of q when
P = 12
A. 2/3
B. 3/2
C. 2
D. 18
Answer:
A
Step-by-step explanation:
Given p² varies inversely as q then the equation relating them is
p² = [tex]\frac{k}{q}[/tex] ← k is the constant of variation
To find use the condition when q = 6, p = 4 , then
4² = [tex]\frac{k}{6}[/tex]
16 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
96 = k
p² = [tex]\frac{96}{q}[/tex] ← equation of variation
When p = 12 , then
12² = [tex]\frac{96}{q}[/tex] ( multiply both sides by q )
144q = 96 ( divide both sides by 144 )
q = [tex]\frac{96}{144}[/tex] = [tex]\frac{2}{3}[/tex] → A
