(c) Compare the experimental probability of the black ball drawn to its

Table:
Color. Times picked
black. 15
white. 12
red. 13

Answers

Answer:

1. 10/40 = 1/4

1b. 15/40 = 3/8

1c. 10/40 = 1/4 and 15/40 = 3/8

Step-by-step explanation:

1. So since there are 40 balls (18 + 12 + 10) and 10 of those balls are black the theoretical probability would just be 10 over 40, ([tex]\frac{10}{40}[/tex]).

1b. On the table there are 15 black balls so that would be, [tex]\frac{15}{40}[/tex].

1c. The theoretical probability is 1/4 and the experimental probability is 3/8.

is -95 an irrational number

Answers

Answer:

I think it is????

Answer:

No, it is not.

An irrational number is real number that cannot be expressed as a ratio of two integers. The number pi or π is a common example of an irrational number since it has an infinite number of digits after the decimal point. Many square roots are also irrational since they cannot be reduced to fractions.

2 - 5

put explanation

Answers

Answer: -3

Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.

The answer is… 2 - 5 = -3
This is simple math so regularly since you will get a negative if it is puted as 2 - 5. So you might as well do the simple math 2 - 5, than as soon as you get your answer than just put a negative sign since it isn’t in the basic number scale, but instead on the negative number scale.

Vance invests S15,000 in an account that pays 3 1/4% simple interest for 72 months. Assuming Vance doesn't
make any other deposits or withdrawals, how much will be in his account after 72 months?

Answers

Answer:

$15487.5

Step-by-step explanation:

Using the formula for calculating the amount as;

Amount = Principal + Interest

Principal = $15,000

Get the interest

Interest = PRT/100

Interest = 15000*13/4 * 3/100 (72months = 3years)

Interest = 195000/400

Interest = $487.5

Amount = 15000 + 487.5

Amount= $15487.5

Hence he will have $15487.5 in his account after 72months

Which expression is equivalent to 128?

Answers

Answer: 2^3 x 2^4

Step-by-step explanation:

The value of the exponential expression is A = 2³.2⁴ = 128

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the value of the exponential equation be A

Now , the first expression is p = 2³

The value of p = 8

Now , the second expression is q = 2⁴

The value of q = 16

From the laws of exponents , we get

p.q = 2³.2⁴ = 2³⁺⁴

The value of A = 2⁷ = 128

Hence , the exponential equation is 2⁷ = 128

Answers

Answer:

Kevin made 5 free throws and 3 two-point shots.

Step-by-step explanation:

Given that Kevin scored 11 points in his last basketball game, to determine if Kevin made two more free throws (one point each) than two-point shots how many of each shot did he make, the following calculation must be performed:

11 x 1 + 0 x 2 = 11

6 x 1 + 4 x 2 = 14

5 x 1 + 3 x 2 = 11

Therefore, Kevin made 5 free throws and 3 two-point shots.

Solve for x

10x - 13.3 = 8x + 12.1

Collect like terms

10x - 8x = 13.3 + 12.1

2x = 25.4

Divide both sides by 2

The public relations officer for a particular city claims the average monthly cost for childcare outside the home for a single child is $600. A potential resident is interested in whether the claim is correct. She obtains a random sample of 14 records and computes the average monthly cost of this type of childcare to be $589 with a standard deviation of $40. Perform the appropriate test of hypothesis for the potential resident using . Approximate the p-value for the test in (a).

Answers

Answer:

Since the calculated value of z= -1.0198 does not lie in the critical region z = ± 1.96 the null hypothesis is accepted and it is concluded that the average monthly cost for childcare outside the home for a single child is $600.

P- value ≈ 0.307823 which supports the null hypothesis .

Step-by-step explanation:

The null and alternate hypotheses are

H0: u = $600 the average monthly cost for childcare outside the home for a single child is $600.

against the claim

Ha: u ≠ $600 the average monthly cost for childcare outside the home for a single child is not equal to $600.

The significance level is set at 0.05

3) The critical region is z = ±1.96

4) The test statistic

Z=x- u /s/√n

z= 589-600/40/√14

z= -11/10.7681

z= -1.0198

6) Conclusion

P- value ≈ 0.307823 which supports the null hypothesis .
