Answer:

Casey's Function has the greater rate of change

Step-by-step explanation:

The graph shows a ROC of 5/1

Get a common denominator (4)

5/1 * 4/4 = 20/4

20/4 > 13/4

Casey's function has a greater ROC.

Add...- 3+(-3) =<br> Thank youuuu!!!!

Wewaii [24]

Answer:

the answer is 0

Step-by-step explanation:

well - 3 plus 3 would just by 0 because if the number with the negative is the biggest then the answer is negative but if the positive number is the biggest then the answer would be positive because there is not a bigger number it would be 0 because 3 and -3 have pretty much the same value other then them being negative and positive

What is the slope of line m? PLEASE HELP !!!

strojnjashka [21]

Slope=rise/run

se how many units it goes up and how many units it goes to the right

from (-3,0) to (0,6), it goes up 6 units total and goes 3 units to right therefor
6/3=2=slope
slope=2
or the longer way is
slope=(y2-y1)/(x2-x1)
slope=(6-0)/(0-(-3))=6/(0+3)=6/3=2

slope=2

what side is the adjacent and what side is the opposite?

KonstantinChe [14]

It depends on which letter you are looking at, but in for this triangle the hypotenuse will always be AB. The adjacent side is the one “left” or “right” of the latter you’re looking at, but never the hypotenuse (stays the hypotenuse). So if you’re looking at “B”, the adjacent side is CB or 21, while AC or 20 is the opposite

A market research firm supplies manufacturers with estimates of the retail sales of their products from samples of retail stores

KengaRu [80]

Answer:

The 95% confidence interval for the difference of means is (7.67, 16.33).

The estimate is Md = 12.

The standard error is sM_d = 2.176.

Step-by-step explanation:

We have to calculate a 95% confidence interval for the difference between means.

The sample 1 (this year's sales), of size n1=36 has a mean of 53 and a standard deviation of 12.

The sample 2 (last year's sales), of size n2=49 has a mean of 41 and a standard deviation of 6.

The difference between sample means is Md=12.

$M_d=M_1-M_2=53-41=12$

The estimated standard error of the difference between means is computed using the formula:

$s_{M_d}=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma_2^2}{n_2}}=\sqrt{\dfrac{12^2}{36}+\dfrac{6^2}{49}}\\\\\\s_{M_d}=\sqrt{4+0.735}=\sqrt{4.735}=2.176$

The degrees of freedom are:

$df=n_1+n_2-1=36+49-2=83$

The critical t-value for a 95% confidence interval and 83 degrees of fredom is t=1.989.

The margin of error (MOE) can be calculated as:

$MOE=t \cdot s_{M_d}=1.989 \cdot 2.176=4.328$

Then, the lower and upper bounds of the confidence interval are:

$LL=M_d-t \cdot s_{M_d} = 12-4.328=7.67\\\\UL=M_d+t \cdot s_{M_d} = 12+4.328=16.33$

The 95% confidence interval for the difference of means is (7.67, 16.33).
