The ratio of mango ice cream to strawberry ice cream is 2 : 5 .Total no. of ice cream is 49.what is the no. of strawberry ice cr

WARRIOR [948]

Answer:

Step-by-step explanation:

First, we add the ratio of the mango to strawberry ice cream and we're going to end up with 2+5=7. If we divide 49 by 7, we're going to find out how much we need to multiply to both sides of the ratio to get the specific amounts. So, if we multiply 7 (49/7) to 5, we're going to get 35. Therefore the number of strawberry ice cream is 35.

Also, we can check this by multiplying 7 to 2 as well, where we will end up with 14. 35 + 14 = 49 so we know this is correct!

What are coefficients in the expression 2+6+10b-8a

tiny-mole [99]

$\boldsymbol{Answer:}$ 10 and -8 ✅

$\boldsymbol{Step-by-step\;explanation:}$

Hii, do you need to know the co-efficients in the expression $"\boldsymbol{2+6+10b-8a}"$ ? No problem! (:

<h3><u>What are Co-efficients?</u></h3>

A "co-efficient" is a number that comes before a variable.

Here there are only two such numbers: "10" and "-8"; 10 comes before b, and -8 comes before a. 2 and 6 don't come before any variables at all, so they are not co-efficients.

Voila! There's our solution, cheers! (:

Hope that this helped! Best wishes.

Answer:

The mean of the sampling distribution of sample proportions will be 0.2

Step-by-step explanation:

Central Limit Theorem for Proportions:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

20% of American adults ages 25 and older had never been married.

This means that $p = 0.2$

So the mean of the sampling distribution of sample proportions will be 0.2
