Answers

Answer 1

Answer:

3.5 in²

Step-by-step explanation:

Given:

Radius (r) = 1.5 in.

Formula for area of half circle = (πr²)/2

Required:

Area of the half circle

Solution:

Plug in the values into the formula for area of half circle.

Thus:

Area = (π × 1.5²)2

= 7.06858347/2

Which of the coordinate points below will fall on the line with the consent of the personality is 1/4 select all that apply

Answers

Answer:

A, C, and D

Step-by-step explanation:

Constant of proportionality, k = y/x

Thus, all points on a line will have the same value of k.

Here, the value of k is given as ¼.

The coordinate points that will fall on a line where k = ¼, will give us the value of ¼ when we divide its y-coordinate by its x-coordinate.

Thus:

(4, 1) will give us k = y/x = ¼

(12, 3) will give us k = y/x = 3/12 = ¼

(20, 5) will give us k = y/x = 5/20 = ¼

Therefore, the options that apply are: A, C, and D

The following set of data represents the age in years of newly married ladies in Desai. 15,25,17,20,22,24,19,16./ This data was collected after Deborah made an allegation that ladies in Desai get married at an age other than 18 years as is required by law. Does this data provide enough evidence at 5% level of significance to believe that the mean ages of ladies getting married in Desai is actually different from 18 years as claimed by Deborah?​

Answers

Answer:

There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.

Step-by-step explanation:

Given the data:

15,25,17,20,22,24,19,16

Using calculator :

Mean value, xbar = 19.75

Standard deviation, s = 3.69

Samoke size, n

H0 : μ = 18

H1 : μ > 18

The test statistic :

Tstatistic = (xbar - μ) ÷ (s / sqrt(n))

Test statistic = (19.75 - 18) ÷ 3.69/ sqrt(8))

Test statistic = 1.75 ÷ 1.3046

Test statistic = 1.34

The Pvalue from test statistic ; df = n - 1 = 8 - 1 = 7

Pvalue = 0.111054

Decision :

If Pvalue < α ; reject H0

0.111053 > 0.05 ` Hence, we fail to reject H0

We can conclude that, There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.

Answers

Answer:

(a) Pentagon

(b) Perimeter= 1435cm

Step-by-step explanation:

Given

[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]

Though the question has a missing attachment, it can still be answered

Solving (a): The name of the polygon

Since we are given 5 side lengths, we can say that the polygon has 5 sides.

Such polygon is referred to as, a pentagon

Solving (b): The perimeter (in cm)

To do this, we simply add up the side lengths

[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]

[tex]Perimeter= 3.65m+ 2.24m+ 2.57m+ 2.24m+ 3.65m[/tex]

[tex]Perimeter= 14.35m[/tex]

Convert to cm

[tex]Perimeter= 14.35*100cm[/tex]

[tex]Perimeter= 1435cm[/tex]

the height of a rectangular prism is 8 meters, and the volume is 308 cubic meters. what is the area of the prisms base in square meters?

Answers

Answer:

The area of the prism's base in square meters is [tex]38.5m^2[/tex].

Step-by-step explanation:

The volume of a rectangular prism is found by multiplying the base of the prism by the height. Since you know that the volume is [tex]308m^3[/tex] and the height is [tex]8m[/tex], you just need to divide the volume by the height to get the area of the base, which would be [tex]\frac{308}{8}[/tex] or [tex]38.5m^2[/tex].

3k = 36

Answers

your answer is k=12. 3x12=36

Answer:

k = 12

Step-by-step explanation:

Given 3k = 36 we want to isolate the variable (k) using inverse operations

So we want to get rid of the 3

3k = 3 times k (multiplication)

The inverse of multiplication is division so to get rid of the * 3 we want to divide by 3. Remember whatever we do to one side we have to do to the other side so we are going to divide each side by 3

3k/3=k

36/3=12

we're left with k = 12
