10/40 and 8/40 and add them,
10/40 + 8/40 = 18/40

2/8 + 1/5 = 9/20

=0.45, but that would say how much pizza they ate in all now would it?

Yoshiko collected some bottle sto be recycled. Twelve were brown. There were 50 more clear bottles than brown ones. There were 3

snow_lady [41]

So we know there are 12 brown ones
brown=12
50 more than 12 is the number of clear bottles so 50+12=62

brown=12
clear=62

30 numbers down from 62 is the number of green ones so 62-30=32

brown=12
clear=62
green=32

12+62+32=106

so Yoshiko collected 106 bottles

Softa [21]

Answer:

She takes 11 grams more protein for breakfast than for a snack.

Step-by-step explanation:

Consider the provided information.

Gina had a scrambled egg and a cup of low-fat milk for breakfast.

She had an oat bran muffin for a morning snack.

First round up the numbers as shown below:

Food Protein (in grams) 1 scrambled egg 6.71 ≈ 7

1 cup shredded wheat cereal 5.51 ≈ 6

1 oat bran muffin 3.98 ≈ 4

1 cup low-fat milk 8.22 ≈ 8

Protein in Breakfast = a scrambled egg + a cup of low-fat milk

Protein in Breakfast = 7+8 = 15

Morning snack she had an oat bran muffin.

Protein in Morning snack = 4

Now we need to find how many more grams of protein did Gina have for breakfast than for a snack?

So subtract them as shown below:

15-4 = 11

Hence, she takes 11 grams more protein for breakfast than for a snack.

The profits of life insurance companies A and B are normally distributed with the same mean. The variance of company B's profit

Lerok [7]

Answer:

23.58-th

Step-by-step explanation:

The standard deviation of company B's profit is:

$\sigma_B=\sqrt{2.25}\sigma_A$

Let X be the profit correspondent to the 14th percentile of company A's profit.

The z-score for 14th percentile of a normal distribution is roughly -1.08.

The z-scores for X in companies A and B are:

$-1.08 = \frac{X-\mu}{\sigma_a} \\z_B = \frac{X-\mu}{\sqrt{2.25}*\sigma_a}\\z_B=\frac{-1.08}{\sqrt{2.25}}\\z_B = -0.72$

The z-score for X in company B's profit distribution is -0.72, which corresponds to the 23.58-th percentile.

The coefficient of xy in the product of (4x2 + 2y) and (3x + y2) is

icang [17]

In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
