Jlenok [28]

Question:

A solar lease customer built up an excess of 6,500 kilowatts hour (kwh) during the summer using his solar panels. when he turned his electric heat on, the excess be used up at 50 kilowatts hours per day .

(a) If E represents the excess left and d represent the number of days. Write an equation for E in terms of d

(b) How much of excess will be left after one month (1 month = 30 days)

Answer:

a. $E = 6500 - 50d$

b. $E = 5000$

Step-by-step explanation:

Given

Excess = 6500kwh

Rate = 50kwh/day

Solving (a): E in terms of d

The Excess left (E) in d days is calculated using:

$E = Excess - Rate * days$

The expression uses minus because there's a reduction in the excess kwh on a daily basis.

Substitute values for Excess, Rate and days

$E = 6500 - 50 * d$

$E = 6500 - 50d$

Solving (b); The value of E when d = 30.

Substitute 30 for d in $E = 6500 - 50d$

$E = 6500 - 50 * 30$

$E = 6500 - 1500$

$E = 5000$

<em>Hence, there are 5000kwh left after 30 days</em>

Write your answer with no spaces and any fraction with “/“

Archy [21]

Answer:

The slope is 1/2

Step-by-step explanation:

Hi!

Disclaimer: Just for this response, I'm going to write it the same way you write a fraction out on paper just so it's easier to see.

First, you plot the two coordinates on the graph:

(0,0) and (2,1)

The formula for slope is $\frac{y1 - y2}{x1 - x2}$

Now we plug in numbers accordingly:

$\frac{0 - 1}{0 - 2}$

Simplify:

$\frac{-1}{-2} \\$

Simplify:

$\frac{1}{2}$

A dog breeder would like to know how many Dalmatian puppies are typically born in a litter. He conducts some research and select

podryga [215]

Answer:

c. 6.2 ± 2.626(0.21)

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 101 - 1 = 100

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 100 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.99}{2} = 0.995$ . So we have T = 2.626
