Answers

Answer:

the area of the circle is 4π

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

The area of the circle = πr^2

where

diameter = 4

So radius = diameter ÷ 2

= 4 ÷ 2

= 2

Now the area of the circle is

= π × 2^2

= 4π

hence, the area of the circle is 4π

Alana rode her bicycle 10 miles on Tuesday and 20 miles on Wednesday. What is the mean absolute deviation of this data?

Answers

Answer:

Step-by-step explanation:

Given that :

Miles ridden in Tuesday = 10

Miles ridden on Wednesday = 20

Sample size, n = 2

Mean :

(10 + 20) / 2

= 30 /2

= 15

Mean absolute deviation :

(|10 - 15| + |20 - 15|) / 2

(5 + 5) / 2

10 / 2

Use the information to answer the following question. Ms. Huynh spent $640 to stay in a hotel for four nights. Each night she spent x dollars on the hotel room as well as a $15 parking fee per day. The equation represents the total amount, in dollars, that Ms. Huynh spent on her hotel. 4(x + 15) = 640 How much money did the hotel room cost for one night, excluding the parking fee? A. $163.75 B. $145.00 C. $175.00 D. $156.25

Answers

Answer:

B. $145.00

Step-by-step explanation:

4(x+15)= 640

or, 4x+60=640

or, 4x = 640-60

or, 4x = 580

or, x = 580/4

x= 145

A bag has 4 red marbles, 5 blue marbles, and 6 green marbles. What is the probability if choosing a red marble from the bag, not putting it back, and then choosing a green marble?

Answers

Answer: 4/35

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 5

Number of green marbles = 6

Total number of marbles = 4+5+6 = 15

When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.

Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:

= 4/15 × 6/14

= 24/210

= 4/35

The length of a rectangle is 1 m less than twice the width, and the area of the rectangle is 21 m?. Find the dimensions of the rectangle.

Answers

Answer:

length = 6

width = 3 1/2

Step-by-step explanation:

l = length

w = width

l = 2w-1

w(2w-1) = 21

2w² - 1 - 21 = 0

(2w - 7)(w + 3) = 0

w = 7/2 = 3 1/2

find 'l':  l = 2(7/2) - 1 = 7-1 = 6

If the given lengths of a triangle are 16 and 10 which can NOT be the third side?

A.21
B.22
C.25
D.27

Answers

Answer:

D.27

Step-by-step explanation:

This is because,

According to Triangle Inequality Property:

Measurement of any two sides of a triangle is always greater than the third side.

Here,

10 + 16 = 26 > 21

10 + 16 = 26 > 22

10 + 16 = 26 > 22

But,

10 + 16 = 26 < 27

Hence,

Option D: 27 can't be the measurement of the triangle.

What is distribution in probability?

By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.

E(X) = ∑( x ∗ P(x))

Given a probability histogram for a discrete random variable X.

We will drive the P(x) for every value of x.

P(X=1)=0.1

P(X=2)=0.2

P(X=3)=0.3

P(X=4)=0.25

P(X=5)=0.15

Putting these values in a summation equation to find E(x)

E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15

E(x) = 3.15

Therefore E(x) for the given histogram far random variable x will be 3.15.
