survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?

Answers

Answer 1

Answer:

12 students

Step-by-step explanation:

225 is 25% of 900 and 25% of 48 is 12.

Answer 2

The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

An administrator surveys a random sample of 48 out of 900 middle school students.

Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.

The proportion of sample = 225/900

= 0.25

In percent sample:

= 0.25x100 %

= 25%

A number of students surveyed were in favor of the new dress code:

= 25% of 48

= (25x48)/100

= 1200/100

= 12

Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

I need 3 reasons why it is important to keep gorillas from becoming extinct. I'll give brainliest. I know that this isnt math but more people answer questions that are in math so... yea

Answers

Answer:

1. gorillas are able to spread the seeds of larger fruits that other, smaller animals are incapable of consuming. When gorillas consume a fruit and later expel the seeds, they are helping to perpetuate diverse, supportive ecosystems.

2. The forest will never be same if the gorillas are gone. Illegal coltan mines (minerals used in smart phone and computer production) are controlled by militia in the gorilla habitat (DRC) and contribute to habitat destruction and poaching.

3. Many local indigenous tribes and communities living alongside the gorilla habitat consider the gorillas to be their patron gods. The Kisimba clan (Bahumba) believe they descended from the gorillas. Their traditional tale tells a story of a gorilla rescuing a man that was lost and stuck high up in a tree. To save the man, a gorilla climbed up the tree and gently placed him on his silver back before carrying him back to safety.

Step-by-step explanation:

Ultimately we cant let gorillas go for much more reasons then just these 3 and they are used for so much in all of their respected environments.

Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°
