Answer:

cos(F) = 40/41

sin(G) = 40/41

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

... Sin = Opposite/Hypotenuse

... Cos = Adjacent/Hypotenuse

In your triangle 41 is the hypotenuse, so these two ratios are appropriate ones to use. The side of length 40 is adjacent to angle F, so

... cos(F) = 40/41

and the side of length 40 is opposite angle G, so

... sin(G) = 40/41

B). sugar= 1 1/2. Flour= 5 1/4

c) your just simplifying to the smallest possible number

Step-by-step explanation:

1/2 doubled= 1 (1/2+1\2)

1 3/4= 7/4

7/4 doubled= 14/4=3 2/4= 3 1/2(1 1/3+1 1/3)

Eight randomly selected customers at a local grocery store spent the following amounts on groceries in a single visit: $216, $18

chubhunter [2.5K]

Answer:

a) 910

b) 828100

c) 144320

Step-by-step explanation:

a. ∑y

This is the sum of all values of y. So

$\sum y = 216 + 184 + 35 + 92 + 142 + 175 + 9 + 57 = 910$

b. (∑y)^2

This is the square of the sum, so the square of 910, that we found in the previous item.

910² = 828100

c. ∑y^2

This is the sum of the squares of each amount spent. So

$\sum y^2 = 216^2 + 184^2 + 35^2 + 92^2 + 142^2 + 175^2 + 9^2 + 57^2 = 144320$

Borrow 1 from the whole number to rewrite 8 10/24.

koban [17]

Answer:

A. $7\frac{34}{24}$

Step-by-step explanation:

We are given the expression, $8\frac{10}{24}$

On re-writing the expression after borrowing 1, we have,

$8\frac{10}{24}$ = $7(\frac{10}{24}+1)$

i.e. $8\frac{10}{24}$ = $7(\frac{10}{24}+\frac{24}{24})$

i.e. $8\frac{10}{24}$ = $7\frac{34}{24}$

Thus, the equivalent expression after borrowing 1 from the given expression is $7\frac{34}{24}$ .

Hence, option A is correct.

inysia [295]

Answer:

B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed.

Step-by-step explanation:

We make this conclusion based on these reasons:

We are told that the "null hypothesis was rejected" after the "manager feels that the pressure variability has changed., meaning the null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.
"changes in the manufacturing process" form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.

It is based on the above reasons that the null hypothesis was rejected.
