if the spinner is fair , it will land on green for 60 times , there are 24% chances for the spinner to land on purple ,For 1000 spins it will land 150 times on blue

<h3>What is Probability ?</h3>

Probability can be defined as the study to predict the likelihood of an event.

It has a range from 0 to 1.

Probability if the spinner is fair is 1/5 for each colour.

As it is spun 300 times

(1/5) * 300 = 60 times

So if the spinner is fair , it will land on green for 60 times.

(b) The probability of landing on purple theoretically is 60times , 20 % chances

but it can be seen from the data provided that for 300 spins , the spinner landed for 72 times

which is 24% , i.e. there are 24% chances for the spinner to land on purple.

(c)Theoretically blue has 20% chances 200 times , But it is seen in the data obtained that

for 300 spins the spinner is landing on blue for 45 times.

For 1000 spins it will land 1000*45/300 = 150 times.

The target temperature for a laboratory is 72° Fahrenheit. It

myrzilka [38]

The inequality |t - 72| ≤ 2 represents the target temperature for a laboratory is 72° Fahrenheit, and it can vary by up to 2° option (D) is correct.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

The question is incomplete.

The complete question is in the picture, please find the attached picture.

We have:

The target temperature for a laboratory is 72° Fahrenheit. It can vary by up to 2°.

Target temperature = 72 degree Fahrenheit

It can vary by up to 2°. (the highest limit)

The temperature in the laboratory represented by t

Now,

inequality represents this situation is:

|t - 72| ≤ 2

Thus, the inequality |t - 72| ≤ 2 represents the target temperature for a laboratory is 72° Fahrenheit, and it can vary by up to 2° option (D) is correct.

Activity

FrozenT [24]

Answer:

Step-by-step explanation:

For the first 30 hours, Andrew will earn 4(30) = $120. For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30). Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:

w = 120 + 5(h - 30).

So, if he works 35 hours, he will earn:

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

If he works 42 hours, he will earn:

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

I hope this helps!

Two middle school classes take a vote on the destination for a class trip. Class A has 25 students, 56% of whom voted to go to S

Kryger [21]

Answer:

The value of <em>n </em>is 15.

Step-by-step explanation:

The combined proportion is computed using the formula:

$P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}$

The information provided is as follows:

$n_{A}=25\\p_{A}=0.56\\n_{B}=n\\p_{B}=0.60\\P=0.575$

Compute the value of <em>n</em> as follows:

$P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}$

$0.575=\frac{25\times 0.56+n\times 0.60}{25+n}\\\\0.575(25+n)=14+0.60n\\\\14.375+0.575n=14+0.60n\\\\0.60n-0.575n=14.375-14\\\\0.025n=0.375\\\\n=15$

Thus, the value of <em>n </em>is 15.
