Answer:

31.25% of Mr. Marcum's students have more than two siblings

Step-by-step explanation:

First count the total amount of students Mr. Marcum has (number of dots on the chart) then count how many have more than two siblings.

Total: 16

>2 siblings: 5

Now divide 5 over 16 and move the decimal to the right two places to find what percent of students have more than two siblings.

5/16=0.3125

move the decimal and the answer is 31.25%

We can solve this question in 2 ways: either using degrees or converting the degrees into radians.

Since, the question says degrees itself and there is no specification of using radians only, so I have solved it using degrees itself.

Part (a):

Perimeter of sector ORS = 2*Radius + Arc RS = 2*21 + 60*  \frac{ \pi }{180} *21 =  \frac{ \pi }{3} *21 = 7 \pi

Part (b):

Area of sector ORS = \frac{60}{360} * \pi * 21^{2} =  \frac{1}{6} * \pi *21*21=  \frac{147}{2} \pi

Area of sector POQ = \frac{36}{360} *  \pi * 14^{2} =  \frac{1}{10} *  \pi * 196 =  \frac{196}{10}  \pi

Thus, area of shaded region
= Area of sector ORS - Area of sector POQ

= \frac{147}{2} \pi - \frac{196}{10} \pi =  \frac{735 - 196}{10}  \pi =  \frac{539}{10}  \pi = 53.9 \pi

A university offers 3 calculus classes: Math 2A, 2B and 2C. In both parts, you are given data about a group of students who have
ankoles [38]

Answer:

4 students

Step-by-step explanation:

The total number of students is given by:

|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N\\51+80+70-15-20-13 +  |A\cap B \cap C|  = 157\\ |A\cap B \cap C| =4

4 students in Group A have taken all three classes.

*The number of students that have taken two classes has be subtracted so those students do not get counted twice

Is a triangle with sides 7 feet, 12 feet, and 14 feet a right, acute or obtuse triangle?
tresset_1 [31]

Answer:

Acute

Step-by-step explanation:

This should be an acute triangle because if this was a right angle, then the three sides should be figured out by the Pythagorean Theorem.

An obtuse angle wouldn't be right either, you need an angle to be over 90.

Randy rented a rectangular storage shed with the volume of 357 ft does it sheds height is 8 and 1/2 ft and the width of is 6 ft
ollegr [7]

Answer:

7 feets

Step-by-step explanation:

Volume of shed, V = 357 feet³

Height of shed, H= 8 1/2 fts

Width of shed, W = 6 ft

Using the relation :

Volume = Length * width * height

357 = L * 6 ft * 17/2 feets

357 feets³ = L * 51 feets²

L = 357 feets³ / 51 feets²

Length, L = 7 feets
