if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?​

If 300 People Come To The Gym On A Given Day, Approximately How Many People Would You Expect To Exercise

Answers

Answer 1
Answer:  120

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Morgan missed 24 questions on her multiple choice math final that had a total of 200 problems. What percentage of questions did Morgan answer correctly?

Answers

Answer:

88%

Step-by-step explanation:

You start out by finding the number of questions she got correct

200 - 24 = 176 questions answered correctly

You then want to divide the number of question she answered correctly by the total number of questions there are.

176/200 or 176 ÷ 200 = 0.88

0.88 = 88/100 = 88%

Step-by-step explanation:

4x15=60

60-30=30

2x15=30

Answer:

Option C is the correct answer.

Step-by-step explanation:

We have been given that a and b are parallel to each with a straight angle.

If a and a are parallel, then angle suspended by a and b will be equal to each other. It is because of Alternate angle of triangle.

Let's head to the question.

According to the above statement, we have the following equation.

2x°= 4x -30°

0r, 2x° - 4° = -30°

0r, -2x° = -30

0r, 2x° = 30°

0r, x = 30°/2°

0r, x = 15°

Hence, x = 15° will show that lines a and b are parallel.

Answers

Usando un sistema de ecuáciones, hay que Ezequiel tiene 11 años.

¿Qué es un sistema de ecuaciones?

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

x: La edad de Sandro.y: La edad de Ezequiel.z: La idad de su padre.

Sandro y Ezequiel son hermanos y el producto de sus edades es igual a la edad de su padre, o sea:

xy = z

Sandro es 8 años menor que Ezequiel, o sea:

x = y - 8.

La suma de su edad y la de su padre es igual a 36, o sea:

x + z = 36.

z = 36 - x

z = 44 - y

En el primer ecuácion:

xy = z

(y - 8)y = 44 - y

y² - 7y - 44 = 0

(y - 11)(y + 4) = 0

y - 11 = 0 -> y = 11.

Part A: 50/100+3/100=x/100

Part B: Emma mistook 50/100 for 5/100 when she added it to 3/100. The correct sum would be 53/100

Answer:

Problem A:
5/10 + 3/100 = ?

Example:
Jake bought a cake. On Monday he ate 5/10 of the cake, he then put it in the fridge to store for later. On Wednesday Jake was looking through the fridge for a snack when he came across his leftover cake. His stomach was a bit small though so he only ate 3/100 of his cake. If Jake wants to finish the cake on Friday how much of the cake does he have to eat?

Problem B:
Emma added the value of 3/100 to 5/100 which is incorrect. The first graph is 5/10 or 1/2. The true value would be; 5/10 + 3/100 = 53/100. In conclusion, your answer would be 53/100 for problem B.
