Answer: exponential

Step-by-step explanation:

its exponential

count the squares in each one

first is 2 squares

second is 4 squares

third is 8 squares

this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3

Answer:

C. 0.5

Step-by-step explanation:

Since a coin has 2 sides and there is the same probability of getting either side, then each side has a 50% or 0.5 probability. Therefore, in order to calculate the expected value of one coin flip we need to multiply the value of each side by its probability and add those values together like so...

1 * 0.5 = 0.5

0 * 0.5 = 0

Now we add these values together...

0.5 + 0 = 0.5

Finally, we can see that the expected value of one coin flip is 0.5

Step-by-step explanation:

3x-2y=5

x+2y=7     Add them up

4x=12     Solve for x

x=3

3+2y=7   Plug it back into either one of the parent functions and solve for y

2y=4

y=2

(3,2) That's the point where the two lines intersect each other.

Answer:

[tex]48\pi[/tex]

Step-by-step explanation:

The figure is 270 degrees. A circle is 360 degrees and 270 is only 75% of this. Very important.

PA is the radius, so it is 8 inches.

Formula for area of a circle: [tex]A = \pi r^2[/tex]

Solve for the area of the whole circle:

[tex]A = \pi (8)^2 = 64\pi[/tex]

Since the circle is only 75%, that is 0.75

Multiply full area by 0.75 to get 75% of the area.

[tex]64\pi *0.75 = 48\pi[/tex]

Answer:

Rational expressions and rational exponents are both basic mathematical constructs used in a variety of situations. ... Their most general difference is that a rational expression is composed of a polynomial numerator and denominator. A rational exponent can be a rational expression or a constant fraction.

Answer:

True

Step-by-step explanation:

x^a = b

x^( a / a ) = b^( 1 / a )

x^1 = b^( 1 / a )

x = b^( 1 / a )

Answer:

x=26

y=11

Step-by-step explanation:

y is equal to the one on the opposite side, so y=11

since 24 and the other side are equal, and the other side is x-2, you do 24+2=26

Answer:

3/5

Step-by-step explanation:

9/15=3/5

since 15 had an a you divide the girls over the people who had an A

The probability that a student has an A given that the student is female is approximately 0.8333 or 83.33%.

Let A be the event that a student has an A in the class, and let F be the event that a student is female. We want to find P(A|F), the probability that a student has an A given that the student is female.

We can use Bayes' theorem to find P(A|F):

P(A|F) = P(F|A) x P(A) / P(F)

where P(F|A) is the probability that a student is female given that the student has an A, P(A) is the overall probability of a student having an A, and P(F) is the overall probability of a student being female.

We are given that there are 20 students in the class, 9 of whom are female and 15 have an A. Therefore, the overall probabilities are:

P(A) = 15/20 = 0.75

P(F) = 9/20 = 0.45

To find P(F|A), the probability that a student is female given that the student has an A, we can use the formula for conditional probability:

P(F|A) = P(A and F) / P(A)

where P(A and F) is the probability that a student has an A and is female.

We know that there are 15 students with an A, and 9 of them are female. Therefore:

P(A and F) = 9/20

Putting everything together, we have:

P(A|F) = P(F|A) x P(A) / P(F)

P(A|F) = (9/20) x (0.75) / (0.45)

P(A|F) ≈ 0.8333

Therefore, the probability that a student has an A given that the student is female is approximately 0.8333 or 83.33%.

Answer:

C

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C
