Answers

Answer 1
45/360 * 4^2 pi = 6.283
ANSWER IS 6.283 (3 decimal places)
Answer 2

Answer:

2π ft²

Step-by-step explanation:

Circle Area:

A = πr²

A = π × (4 ft)²

A = 16π ft²

Sector Area:

A = (45°)/(360°) × 16π ft²

A = 2π ft²

The table shows the length y (in inches) of a person’s hair after x months.

months x: 0 3 6
hair Length y:11.0 12.5 14.0

a. Write and graph a linear function that relates y to x .
y=
b. Interpret the slope and the y-intercept

The slope indicates that the hair length increases by what
inch per month. The y-intercept indicates that the initial hair length is what
inches.

Answers

The difference between 11.0 and 12.5 is 1.5 and same with 12.5 and 14.0, so 1.5 is what the hair increases by every THREE months but if you want to find PER month, you are going to divide 1.5 by those 3 months to get .5 inches per month, so your slope will be 1/2

Amelia went shopping for a new camera because of a sale. The store was offering a 30% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?

Answers

Amelia would have to multiply the number 7/10 on the price on the tags that she has to pay.

What is percentage?

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

The discount on new camera bought by Amelia = 30%.

To find the number that Amelia should multiply to pay,

Let The required number be x,

and total price of the camera is 100%

So after discount the price of camera = 100 - 30 = 70%

Implies that,

100 × x = 70

x = 70 / 100

x = 7 / 10

So the required number is 7/10 that Amelia should multiply the price she would have to pay.

Find the mean,median ,and mode of the following set of data Weight of the 7 fish that were caught (lbs) are: 12,3,7,8,9,12,10

Answers

Given:

The data values are:

12, 3, 7, 8, 9, 12, 10

To find:

The mean,median ,and mode for the given set of date.

Solution:

We have,

12, 3, 7, 8, 9, 12, 10

Arrange the values in ascending order.

3, 7, 8, 9, 10, 12, 12

Mean of the data set is:

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]\text{Mean}=\dfrac{3+7+8+9+10+12+12}{7}[/tex]

[tex]\text{Mean}=\dfrac{61}{7}[/tex]

[tex]\text{Mean}\approx 8.7143[/tex]

Number of observations is 7 which is an odd number. So, the median is:

[tex]Median=\dfrac{n+1}{2}\text{th term}[/tex]

[tex]Median=\dfrac{7+1}{2}\text{th term}[/tex]

[tex]Median=\dfrac{8}{2}\text{th term}[/tex]

[tex]Median=4\text{th term}[/tex]

The 4th term from the arranged data set is 9.

[tex]Median=9[/tex]

Here, the most frequent number is 12 because it occurs 2 times. So, the mode of the data set is 12.

Therefore, the mean of the data set is 8.7143, median is 9 and mode is 12.

Answers

Answer:

[tex]a =\frac{\sqrt 3}{2}[/tex] mi

[tex]b =\frac{1}{2}[/tex] mi

Step-by-step explanation:

Given

The attached triangle

Required

Find a and b

To do this, we make use of the following trigonometry ratio

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

So, we have:

[tex]\sin(60) = \frac{a}{c}[/tex]

[tex]\sin(30) = \frac{b}{c}[/tex]

Where

[tex]c = 1[/tex]

So, we have:

[tex]\sin(60) = \frac{a}{c} =\frac{a}{1}[/tex]

[tex]\sin(60) = a[/tex]

[tex]a = \sin(60)[/tex]

In radical form:

[tex]\sin(60) = \frac{\sqrt 3}{2}[/tex]

Hence:

[tex]a =\frac{\sqrt 3}{2}[/tex]

[tex]\sin(30) = \frac{b}{c}[/tex]

[tex]\sin(30) = \frac{b}{1}[/tex]

[tex]\sin(30) = b[/tex]

Rewrite as:

[tex]b =\sin(30)[/tex]

In radical form:

[tex]\sin(30) = \frac{1}{2}[/tex]

Hence:

[tex]b =\frac{1}{2}[/tex]

Answers

Answer:the ages of the youngest and the eldest is 4 years and 20 Years respectively

Step-by-step explanation:

Ratio of the ages of three children is 2:5:1.

Total ratio =2+5+1=8

So that

the 1st Child's age =2/8 x 32=8  years

2nd  Child's age =5/8 x 32= 20 years

3rd Child's age =1/8 x 32= 4  years

Answer:

This is binomial.

p = 2/7

mean = np = 5*2/7 = 10/7 = 1.42857

standard deviation = sqrt(npq) = sqrt(5*2/7*5/7) = 1.01015

Step-by-step explanation:

Work Shown.

The probability that exactly two of the five students of the class were born on weekend is 0.2975

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

n = 5

The probability that any student was born on weekend, P(W) = (2 / 7)

and, the probability that any student was not born on weekend

P(W') = {1 - P(W)}

        = {1 - (2 / 7)}

        = (5 / 7).

Thus, the probability that exactly two of the five students of the class were born on weekend

= ([tex]^5C_2[/tex]) x {P(W)}² x {P(W')}³

= 10 x {(2 / 7)²} * {(5 / 7)³}

= 10 x (4 / 49) x (125 / 343)

= (5000 / 16807)

≈ 0.2975
