Find the area of the semicircle. Round your answer to the nearest hundredth.

Answer:

B. 1/4

Step-by-step explanation:

The easiest way to find the answer here is to (if you have one) use a calculator to divide each fraction.

When divided 1/4, you get .25, and as the explanation says, "The first two places after a decimal point are the same as a percentage: 0.15 is equal to 15%, and 0.3 is equal to 30%."

So, moving the decimal to the right two times will give you your probability of 25%.

Hope this helps :)

18π

Step-by-step explanation:

so first you need to find the area of both semi- circles. To do this you will use the formula 1/2πr^2 since it is half the area of a circle.

So for the smaller semi circle you do 1/2×π×8^2 to get 32πcm^2.

Now for the large semicircle you do 1/2×π×10^2 to get 50πcm^3.

Now you take 50π from 32π to get just the area of the shaded region.

This is 18π or 56.55cm^2

The number of the smaller cube-shaped boxes that Manuel can fit into the large cube-shaped box is: 64.

Volume of a cube = a³, where a is the edge length of the cube.

Volume of the smaller cube-shaped boxes = a³ = 6³ = 216 in.³

Volume of the larger cube-shaped box = a³ = 24³ = 13,824 in.³

Number of the smaller boxes that will fit into the large box = 13,824/216 = 64 smaller cube-shaped boxes.

Answer:

Mikhail is 5 years old

Step-by-step explanation:

Represent each member with a variable.

X= Gabrille

Y=Mikhail

X+Y=20 (sum of their ages is 20)

X=3y (Gabrille is 3 times Mikhails age)

Substitute 3Y into the first equation (simultaneous equation)

. 3y+y=20

. 4y=20 (divide both sides by 4)

y=5

To check your answer.

X+5=20

X=20-5

Step-by-step explanation:

Using the concept of independent events, it is found that the correct statement is:

a and b are independent events because p(a∣b) = p(a) = 0.75.

Two events, A and B, are independent if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

In this problem, the events are:

In this problem, out of 300 students, 225 have surfed, hence:

[tex]P(A) = \frac{225}{300} = 0.75[/tex]

48 have gone snowboarding, hence:

[tex]P(B) = \frac{48}{300} = 0.16[/tex]

36 have done both, hence:

[tex]P(A \cap B) = \frac{36}{300} = 0.12[/tex]

The multiplication is:

P(A)P(B) = 0.75 x 0.16 = 0.12.

That is, the probability of A given B is P(A|B) = P(A) = 0.75, hence they are independent.

Division: 10 ÷ 3

Mixed Number 3 and 1/3

Answer:

10/3 in a mixed fraction is 3 1/3.

Let us convert the improper fraction to a mixed number.

Step-by-step explanation:

Converting an improper fraction to a mixed number involves dividing the numerator by the denominator.

And we keep the quotient part as separate

The quotient of 10 divided by 3 is 3

While the remainder of 10 divided by 3 is 1

The mixed number is written as Quotient (Remainder/Divisor), i.e., 3 1/3

Thus, 10/3 in a mixed fraction is 3 1/3.

Answer:

Step-by-step explanation:

divide the figure into 2 rectangle the one on top and bottom. Th one on top's dimensions would be length = 9 width = 3.

the bottom rectangles dimensions would be length = 5 (because 9-4) and width would be 3 (because 6-3)

so top rectangle : 9*3 = 27

bottom rectangle: 5*3 = 15

27+15 = 42

Answer:

[tex]A_{total} = 42\ cm^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the left rectangle

[tex]A = l * w[/tex]

[tex]A = 6\ cm * (9\ cm - 4\ cm)[/tex]

[tex]A = 6\ cm * 5\ cm[/tex]

[tex]A = 30\ cm^2[/tex]

Step 2:  Determine the area of the right rectangle

[tex]A = l * w[/tex]

[tex]A = 4\ cm * 3\ cm[/tex]

[tex]A = 12\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 30\ cm^2 + 12\ cm^2[/tex]

[tex]A_{total} = 42\ cm^2[/tex]

Answer: [tex]A_{total} = 42\ cm^2[/tex]

The theoretical domain is all real numbers greater than or equal to one and less than or equal to two. Then the correct option is C.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

Kellen runs for at least 1 hour but for no more than 2 hours. He runs at an average rate of 6.6 kilometers per hour. The equation that models the distance he runs for t hours is d = 6.6t

Then the domain of the function d will be a real number.

But in the problem, the value of t is more than or equal to one but less than or equal to two.

1 ≤ t ≤ 2

Using the normal distribution, it is found that approximately 40% of the scores are greater than 413.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that the mean and the standard deviation of the scores are given by:

[tex]\mu = 400, \sigma = 50[/tex]

Approximately 40% of the scores are greater than the 60th percentile, which is X when Z = 0.253.

Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.253 = \frac{X - 400}{50}[/tex]

X - 400 = 50(0.253)

X = 412.65.

Rounding up, approximately 40% of the scores are greater than 413.

Answer:

y=36,x=108,z=30

Step-by-step explanation:

1)180°=72°+(3y)°

=>(3y)°=180°-72°

=>(3y)°=108°

=>3y=108

=>y=36

2)(x)°=(3y)°=>x=108

3)(3z+18)°=108°=>3z+18=108=>3z=90=>z=30

Answer:

x = 108

y = 36

z = 30

Step-by-step explanation:

(x)° + 72° = 180° (interior angles on the same side of transversal)

-> (x)° = 180 - 72°

-> (x)° = 108°

-> x = 108

(3y)° = (x)° (corresponding angles)

-> 3y = x

-> 3y = 108

-> y = 108/3

-> y = 36

(3z + 18)° = (x)° (corresponding angles)

-> 3z + 18 = x

-> 3z + 18 = 108 - 18

-> 3z = 108 - 18

-> 3z = 90

-> z = 90/3

-> z = 30

Answer:

Below in bold.

Step-by-step explanation:

The general form of a linear function can be written as:

n(p) = kp + C      where k and C are constants.

So substituting the given data:

8000 = 3k + C

5200 = 5k + C    Subtract

2800 = -2k

k = -1400

and C = 8000 - 3(-1400) = 12200

a. So the equations is:

n(p) = -1400p + 12200

b.

For a charge p of $6.50;

n(p)  = -1400*6.5 + 12200

= 3100 balls.
