steve made a mistake in writing a two step equation. Instead of multiplying by 3 and adding 7, he multiplied by 7 and added 3 to

rjkz [21]

Answer:

The correct answer of the problem is 1.

Step-by-step explanation:

Let the original number on which the wrong procedure is applied is x.

Now, Steve multiplied by 7 and then added 3 to get the answer of - 11.

So, 7x + 3 = - 11

⇒ 7x = - 14

⇒ x = - 2

Now, the correct step to get the answer is multiplying by 3 and adding 7.

Hence, the correct answer of the problem is (- 2) × 3 + 7 = - 6 + 7 = 1 (Answer)

One of the tallest living men has a height of 236 cm. One of the tallest living women is 224 cm tall. Heights of men have a mean

Roman55 [17]

Answer:

A. The woman is relatively taller because the z score for her height is greater than the z score for the man's height.

Step-by-step explanation:

Whoever has the highest z-score, is taller relative to the population of the same gender.

The z-score of a value X in a set with mean $\mu$ and standard deviation $/sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

Solution:

Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:

$Z = \frac{X - \mu}{\sigma} = \frac{236-170}{6} = 11$

Heights of women have a mean of 161 cm and a standard deviation of 5 cm.

One of the tallest living women is 224 cm tall. The z-score of the women's height is

$Z = \frac{X - \mu}{\sigma} = \frac{224-161}{5} = 12.6$

The women has a higher z-score, so she is relatively taller.

The correct answer is A

vovikov84 [41]

Answer:

The answer is the option D

the minimum number of students will be $19$

Step-by-step explanation:

Let

x-------> the minimum number of students

we know that

$15x\geq 275$ ------> inequality that represent the situation

The domain of the inequality is the interval-------> $[0,24]$

Solve for x

Divide by $15$ both sides

$x\geq 275/15\\ x\geq 18.33$

the minimum number of students will be $19$

A bacteria population doubles every minute. Explain why this population growth cant be modeled on a graph

Kisachek [45]

Answer:

It can be modeled on an exponential graph

Step-by-step explanation:

Bacteria is <u><em>doubling</em></u> by the minute. This means that if there are 2 bacteria in the first minute, there would be 4 in the second, 8 in the third, 16 in fourth, and so on. This can be modeled using an exponential graph, where a number is constantly increasing by multiplying.
