Triangle ABC with vertices A(4, −6), B(2, −8), and C(−10, 4) is dilated by a scale factor of 2 to obtain triangle A′B′C′. Which

statement best describes triangle A′B′C′?
It is similar to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).
It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).
It is congruent to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2).

zaharov [31]
First you have to subtract the two one time costs to find the cost delta:

44,641 - 18,720 = 25,921

Then you would have to subtract the variable costs to find the delta:

24.50 - 12.25 = 12.25 per book

Since we know that the 25921 isn't changing we need to divide by the delta of 12.25 per book to find out how many books it will take to make up the 25921

25,921/12.25 = 2116 Books

y2 = 14

y1 = 2

Solution

m = (14 - 2) / (8 - 2)

m = 4 / 4 = 1

Remark

Why is the slope one? I should be 2 shouldn't it? No because there is a common factor to be taken out -- the common factor is 2Answer:

Step-by-step explanation:

y = 2x - 2

x        y

2       2

4       6

6      10

8       14

I will use Desmos to get the line.

The slope  should be 2

Formula

Slope (m) = ( (y2 - y1) / (x2 - x1) )

Givens

x2 = 8

x1 = 4

y2 = 14

y1 = 6

Solution

m = ( (14 - 6) / ( 8 - 4)

m = 8 / 4

m = 2

The average number of pounds of sliced ham ordered per customer at the deli where Dennis used to work was 1.4, but at his new jo
pentagon [3]

Answer:

(a) Null Hypothesis, H_0 : \mu \leq 1.4 pounds

    Alternate Hypothesis, H_A : \mu > 1.4 pounds

(b) If the test statistics is more than the critical value of t at 31 degree of freedom, then we will reject our null hypothesis.

(c) The value of t test statistics is 1.886.

(d) We conclude that the average amount of ham bought is higher at the new store.

Step-by-step explanation:

We are given that the average number of pounds of sliced ham ordered per customer at the deli where Dennis used to work was 1.4, but at his new job, the average of the 32 people who have ordered ham so far is 1.5 pounds, with a standard deviation of 0.3 pounds.

<em>Let </em>\mu<em> = average amount of ham bought at the new store.</em>

So, Null Hypothesis, H_0 : \mu \leq 1.4 pounds     {means that the average amount of ham bought is lesser than or equal to 1.4 pounds at the new store}

Alternate Hypothesis, H_A : \mu > 1.4 pounds     {means that the average amount of ham bought is higher at the new store}

The test statistics that would be used here <u>One-sample t test statistics</u> as we don't know about the population standard deviation;

                        T.S. =  \frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }  ~ t_n_-_1

where, \bar X = sample average of ham ordered = 1.5 pounds

            s = sample standard deviation = 0.3 pounds

            n = sample of people = 32

So, <u><em>test statistics</em></u>  =  \frac{1.5-1.4}{\frac{0.3}{\sqrt{32} } }  ~ t_3_1  

                               =  1.886

The value of t test statistics is 1.886.

Since, in the question we are not given with the level of significance so we assume it to be 5%. Now, at 5% significance level the t table gives critical value of 1.6955 at 31 degree of freedom for right-tailed test.

<em>Since our test statistics is more than the critical values of t as 1.886 > 1.6955, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which </em><u><em>we reject our null hypothesis</em></u><em>.</em>

Therefore, we conclude that the average amount of ham bought is higher at the new store.
