Irene makes 4 2/3 cups of pancake batter . she splits the

kvv77 [185]

Answer:

Step-by-step explanation:

An estimate is usually a guess, but I somehow think that's not what you want.

She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.

The other batter is the one you are interested in. How big is it?

Estimate: One

The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.

Actual Size: Two

4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.

Whole number subtraction: 4 - 2 = 2

Fraction subtraction: 2/3 - 1/4

Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.

2/3 to 12s: (2*4)/(3*4) = 8 / 12
1/4 to 12s: (1 *3) / (4*3) = 3/12
8/12 - 3/12 = 5/12

So the actual size of the batter containing the walnuts is 2 5/12

What is the first number in the missing dimension v=72fts2l=4ft. W=3ft

Jlenok [28]

Volume equals length times with times height
V= LwH
72=4 times 3 times H
72= 12H
Divide by 12
H= 6

Mr. Dylan asks his students throughout the year to record the number of hours per week they spend practicing math at home. At th

hoa [83]

Answer:

The second plot.

Step-by-step explanation:

In the picture attached, the scatter plots are shown.

The second plot has minimum residuals and its residuals are randomly distributed. Residual is computed as follows:

residual = measured - predicted

It easy to see that residuals of the first option are greater than the second option.

Line of the second option is better than those from third and fourth options because residuals of the second option are randomly distributed, while in the third option, residuals are mostly negative; and in the fourth option, they are mostly positive.

There are 15 red, 14 green, and 9 yellow balls in a dark room. What is the minimum number of balls that Alicia needs to take so

Tems11 [23]

Answer:

32

Step-by-step explanation:

1. If you take 12 balls, 9 could be yellow and 3 could be red. We want at least 12 of the same color, so 30 balls isn't a good minimum

2. If you take 30 balls, 9 could be yellow, 10 could be red and 11 could be green. We want at least 12 of the same color, so 30 balls isn't a good minimum.

3. If you take 31 balls, 9 could be yellow, 11 could be red and 11 could be green. We want at least 12 of the same color, so 31 balls isn't a good minimum.

4. If you take 32 balls, 9 could be yellow, 11 could be red and 12 could be green or 9 could be yellow, 12 could be red and 11 could be green or 7 could be yellow, 13 could be red and 12 could be green or 9 could be yellow, 11 could be red and 12 could be green.

We want at least 12 of the same color, and we have it from the different samples of the 4th trial.

So, 32 balls is the minimum number of balls
