I think it will be 'heat' because it doesn't change - only your material changes.

How many years of college do you have to do to go to the nfl?

serg [7]

!!four years!!
Players wanting to enter the NFL draft must use all of their college eligibility before the next college football season starts. Typically, that means they complete four years of college and graduate with a degree of their choosing. Those who have not yet graduated can petition the NFL to enter the draft early

Electric vehicles make up a very small proportion of the overall car market, but by how much has that proportion increased? Inde

Minchanka [31]

Given Information:

The proportion of electric cars sold in 2012 = p₁ = 0.1%

The proportion of electric cars sold in 2016 = p₂ = 0.5%

Sample size of electric cars in 2012 = n₁ = 10,000

Sample size of electric cars in 2016 = n₂ = 20,000

Confidence level = 95%

Required Information:

Change in the proportion of electric cars sold from 2012 to 2016 = ?

Answer:

Change in the proportion of electric cars sold from 2012 to 2016 = (0.284%, 0.516%)

Step-by-step explanation:

The change in the mean is given by

$\mu = p_2 - p_1\\\\\mu = 0.005 -0.001\\\\\mu = 0.004\\\\$

The change in standard error is given by

$SE = z\cdot\sqrt{\frac{p_1(1 - p_1)}{n_1} + \frac{p_2(1 - p_2)}{n_2} }$

Where z is the value of z-score corresponding to 95% confidence level.

$z_{\alpha/2} = 1 - 0.95 = 0.05/2 = 0.025\\\\z_{0.025} = 1.96\\\\$

$SE = 1.96\cdot\sqrt{\frac{0.001(1 - 0.001)}{10,000} + \frac{0.005(1 - 0.005)}{20,000} } \\\\SE = 1.96\cdot 0.00059\\\\SE = 0.00116\\\\$

The change in the proportion of electric cars is

$\mu \pm SE \\\\0.004\pm 0.00116 \\\\(0.004-0.00116) \: and \: (0.004-0.00116)\\\\(0.00284, \: 0.00516)\\\\(0.284\%, \: 0.516\%)$

Therefore, we are 95% confident that the change in the proportion of electric cars sold from 2012 to 2016 is between (0.284%, 0.516%)

The table above gives values of f, f’, g, and g’ at selected values of x. If h(x) = f(g(x)), then h’(1) =

Anit [1.1K]

Answer:

h'(-1) = 5

Explanation:

Given - The table above gives values of f, f’, g, and g’ at selected values

of x.

x f(x) f'(x) g(x) g'(x)

-1 6 5 3 -2

1 3 -3 -1 2

3 1 -2 2 3

To find - If h(x) = f(g(x)), then h’(1) = ......?

Proof -

Given that,

h(x) = f(g(x))

⇒h'(x) = f'(g(x))

⇒h'(1) = f'(g(1))

Now,

g(1) = -1

⇒f'(-1) = 5

⇒h'(-1) = 5
