Answer:

She should have multiplied by 4, not divided

Step-by-step explanation:

Given

\frac{H}{4} - 11 = 13 ( add 11 to both sides ) ← correct

\frac{H}{4} = 24 ( multiply both sides by 4 to clear the fraction )

H = 4 × 24 = 96

H is divided by 4, thus the inverse operation is to multiply

What else would you need to measure the area of something
kumpel [21]

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Over the past several months,the water level of a lake has been decreasing by 12% each week.If the highest water level before th
pickupchik [31]

Answer:

The level was 402.7ft. at the end of two weeks.

Step-by-step explanation:

First, we need to find the amount of decrease for the first week.

520 x 0.12 = 62.4

Now, we subtract the change for the first week.

520 - 62.4 = 457.6

Next, we find the change for the second week.

457.6 x 0.12 = 54.912

Then, we subtract the change for the second week.

457.6 - 54.912 = 402.688

And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.

Find and interpret the percentile for colorado which has 10.1
Lelechka [254]
The problem here is incomplete, but I found a problem online that must be the same to this. The picture is attached. The figure shown is a stemplot. The numbers to the left of the bar is the stem, while numbers to the right are the leaves. So, if you want to find 10.1%, find the row where the left number is 10. Then, find the corresponding 1 among the numbers to the right. That is 10.1% for the older folks living in Colorado.

Your friend, Jamie, rolled a number cube and got the number 5. On his next turn, he says he won’t be able to roll another 5 beca
olga nikolaevna [1]

Answer with explanation:

When a Number cube numbered from 1 to 6 is rolled once,

total possible outcome ={1,2,3,4,5,6}

Probability of each outcome that is ,

P(1)=P(2)=P(3)=P(4)=P(5)=P(6)=\frac{\text{total favorable outcome}}{\text{Total possible outcome}}=\frac{1}{6}

→So, each outcome has equal chance when a die is rolled 6 times.But in actual ,that is in experimental probability this seems impossible.

→When you are dealing with theoretical probability,we state that ,yes when a number cube is rolled six times each outcome has equal chance of coming.

→No, my friend is Incorrect,because here he is performing experiment in real life,there are chances that in next five trials ,number 5 only appears on the number cube,but  when number of rolling of number cube becomes very high and higher, then probability of occurring of each number becomes same.
