Answer and Step-by-step explanation:

So, the format you should choose is the second one.

This is what goes in each box:

[4] (p - [6]) = [12]

The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.

Now, we solve for p.

Divide each side by 4.

p - 6 = 3

Now, add 6 to each side.

p = 9.

Each item cost 9 dollars.

The U.S. Energy Information Administration claimed that U.S. residential customers used an average of 10,608 kilowatt hours (kWh

Marat540 [252]

Answer:

The calculated value Z = 1.4460 < 1.96 at 0.05 level of significance.

The null hypothesis is accepted

A local power company believes that residents in their area use more electricity on average than EIA's reported average

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 10,608 kWh of electricity this year.

Given that the size of the sample n = 187

Given that mean of sample x⁻ = 10737 kWh

The Standard deviation of the Population = 1220kWh

Level of significance = 0.05

The critical value (Z₀.₀₅)= 1.96

Step(ii):-

Null Hypothesis: H₀:μ > 10608 kWh

Alternative Hypothesis: H₁: μ < 10608kWh

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{10737- 10608 }{\frac{1220}{\sqrt{187} } }$

Z = 1.4460

Final answer:-

The calculated value Z = 1.4460 < 1.96 at 0.05 level of significance.

The null hypothesis is accepted

A local power company believes that residents in their area use more electricity on average than EIA's reported average.

Help please this math is wack I am not having a good time

Mariana [72]

Answer:

The third term is -25.

Step-by-step expanation:

d(1)=3

From this equation, we know the first term is 3.

d(n)=d(n−1)−14

This looks like a recursive formula. It is used to find the next term.

n is the variable for the term number that you are solving for.

d(n-1) is the term value before the what you are looking for.

To find the 2nd term, use the formula and substitute values known:

d(n)= d(n−1)−14

d(2) = d(2-1) - 14

d(2) = d(1) - 14

We know d(1)=3

d(2) = 3 - 14

d(2) = -11

Find the third term using the same method:

d(n) = d(n−1)−14

d(3) = d(3−1)−14

d(3) = d(2)−14

d(3) = -11 - 14

d(3) = -25

The two triangles are similar, What is the length of DE?

horsena [70]

<h2>Answer:</h2>

This is easy. All you need to do is set up a proportional relationship.

A proportional relationship uses variables to show similarities, in this case, in triangles.

$\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2$

x represents the missing side.
