Answer:

  6π

Step-by-step explanation:

The circumference of a circle is given by the formula ...

  C = πd

The arc length of a semi-circle is half that, so is ...

  arc length = (1/2)πd = 1/2·π·12 = 6π . . . units

Options are;

A) the Normal distribution, with mean 2 and variance 1

B) the binomial distribution, with parameters n = 4 and p = 0.5

C) the poisson distribution, with parameters λ = 4/10

D) none of the above

Answer:

B) the binomial distribution, with parameters n = 4 and p = 0.5

Step-by-step explanation:

Number of times card is shuffled is 4 times. Thus; n = 4

X is the number of cards in the time shuffled that corresponds to a male.

We are told there are 10 students and 5 are male and 5 female.

Thus, probability that it corresponds to a male is;

P(corresponding to a male) = 5/10 = 0.5

According to binomial probability distribution, the parameters are;

p = 0.5

n = 4

q = 1 - 0.5 = 0.5

Answer:

[tex]A=7569\pi \ ft^2[/tex]

Step-by-step explanation:

The diameter of a sphere is 87 feet.

We need to find its surface area. The formula for surface area is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the sphere

[tex]A=4\pi \times (\dfrac{87}{2})^2\\\\=7569\pi \ ft^2[/tex]

So, the surface area of the sphere is equal to [tex]7569\pi \ ft^2[/tex].

Answer:

x = 45

Step-by-step explanation:

0.36(18) + 0.04x = 0.12(24 + x)

6.48 + 0.04x = 2.88 + 0.12x

0.04x - 0.12x = 2.88 - 6.48

-0.08x = -3.6

0.08x = 3.6

x = 3.6/0.08

x = 45

Answer:

-2(4-1)

Step-by-step explanation:

Do parentheses first because of PEMDAS. That means 4-1 equals 3. Then take -2 and times it by the 3 to get -6.

Answer:

The answer would be -2(4-1)

Step-by-step explanation:

-2 multiplied by 4 is -8

-2 multiplied by -1 is 2

you then add -8 and 2 which equals -6

Answer:

the eqaution would be

C=1.25h-0.5

The solution for 4 boxes would be

4.50 dollars

Step-by-step explanation:

Well c in this case is total

h is the amount of boxes

Since each box (h) cost $1.25 each, you multiply 1.25 by h.

Then that one time coupon off his total would be just -0.50

Answer:

x = 1/8

Step-by-step explanation:

The value of x is 1/8.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

64x = 8

Solve for x.

64x = 8

Divide both sides with 64.

x = 8/64

x = 1/8

Thus,

The value of x is 1/8.

Answer:

a = 14

Step-by-step explanation:

The angles share a common side terminal side, so they are supplementary angles. This also means they add up to 180º.

8a + (5a - 2) = 180

Combine like terms.

13a - 2 = 180

13a = 182

Divide both sides by 13.

a = 14

This is your answer.

Check your work by plugging "a" back into the original equation.

8a + (5a - 2) = 180

8(14) + [5(14) - 2] = 180

112 + (70 - 2) = 180

112 + 68 = 180

180 = 180

Your answer is correct.

Answer:

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

[tex]h = -16x^2 + 16x[/tex]

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

[tex]-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1[/tex]

So, it will touch the ground at x = 0 and x = 1 seconds.
