Answer:It is given that Joe was being exposed to an electromagnet shrinking machine. Because of this his height started decreasing .

Given,

The decrease was at a constant rate per second.

In 1.5sec, the height is decreased by 120cm.

So,

Variation per second =

Change in each second would be with negative sign indicate's decrease .

Hence, Answer is “-80” .

A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble. What is the probability of choosing a green marble, not replacing it
lys-0071 [83]

The probability for choosing green and red is \frac{1}{12}

<u>Solution:</u>

Given that , A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble.

We have to find what is the probability of choosing a green marble, not replacing it, and then choosing a red marble?

Now, we know that,

\text { probability of an event }=\frac{\text { number of favourable outcomes }}{\text { total number of outcomes }}

So, total possible outcomes = 1 red + 1 yellow + 1 blue + 1 green = 4

\text { Now, probability for green marble }=\frac{1 \text { green marble }}{4 \text { marbles }}=\frac{1}{4}

And now, total outcomes will be only 3 as we are not replacing the picked marble.

\begin{array}{l}{\text { Then, probability for red marble }=\frac{1 \text { red marble }}{3 \text { marbles }}=\frac{1}{3}} \\\\ {\text { Then overall probability }=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12}}\end{array}

Hence, the probability for choosing green and red is \frac{1}{12}

There are 90 girls and 60 boys in the sixth grade at a middle school. Of these students, 7 girls and 2 boys write left-handed. W
Radda [10]

Answer:

6%

Step-by-step explanation:

  1. 90 + 60 = 150
  2. 7 + 2 = 9
  3. Set up a proportion: \frac{9}{150} = \frac{x}{100}  
  4. Cross multiply, then divide: 9 × 100 = 900, 900 ÷ 150 = 6
  5. So, 6% of students in 6th grade were left-handed

I hope this helps!

Can I have help with 42?
Sphinxa [80]
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
