The Area of the sector is: A = 95.4 cm²

Step-by-step explanation:

Given

Central angle Ф = 135°

radius r = 9 cm

To determine

Area of the sector = ?

The Area of the sector can be calculated using the formula

A = Ф/360 × πr²

substitute Ф = 135°, r = 9 and π = 3.14

A = 135/360 × (3.14) (9)²

A = 95.4 cm²

Therefore, the Area of the sector is: A = 95.4 cm²

Step-by-step explanation:

Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

a college says it admits only people with sat scores among the top 10%. how high an sat score does it take to be g

Answers

Full question:

Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.

If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?

Answer and explanation:

To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students

A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28

We use algebra to find the score to be eligible thus:

1.28=x-500/100

x-500=128

x=128+500

x=628

Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores

help asappp!!!

Answers

Answer:

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Step-by-step explanation:

We convert all given values to decimal

Hiroshi found that:

a) For vanilla ice cream

3/5 of his class prefers vanilla ice cream

3/5 to decimal = 0.6

b) For Chocolate ice cream

26% prefers chocolate ice cream

26% to decimal = 0.26

c) For strawberry ice cream

0.14 prefers strawberry ice cream

0.14 = 0.14

Arranging the numbers in order from least to greatest, we have :

0.14, 0.26 , 0.6

The kind of ice cream the least number of students prefer is Strawberry ice cream.
