Rashaad owns a small business selling used books. He knows that in the last week 13 customers paid cash, 50 customers used a debit card, and 53 customers used a credit card. Based on these results, express the probability that the next customer will pay with a debit card as a fraction in simplest form.

Answers

Answer:

25/58

Step-by-step explanation: Ok, your step one should be to add all the previous customer values together to see what the total pool of values is. 13+50+53=116, this becomes your denominator. Then, you see that out of these 116 customers in the past week, 50 used a debit card. So based on this data, we can assume that 50 out of every 116 customers will use a debit card. The fraction is thus 50/116. Then it needs to be simplified. Divide the numerator and denominator by 2, and BAM 25/58 is your final answer.

Probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).

What is probability?

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes for a given event."

Formula used

Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Given,

Number of customers paid through cash = 13

Number of customers paid through debit card = 50

Number of customers paid through credit card = 53

Total number of customers = 13 + 50 + 53

                                             = 116

Substitute the value in the formula we get,

Required probability =  (50 / 116)

                                   = (25 / 58) (simplest fraction form)

Hence, probability that next customer will pay with debit card is (25 / 58) (simplest fraction form).

Step-by-step explanation:

I took the test.

The quadratic regression equation best fits the data set is 2.608x²  -155.264x + 1568.064 option second is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the quadratic regression equation best fits the data set:

y = Ax² + Bx + C

From the data set, we can calculate the value of the A, B and C:

A = 2.608

B = -155.264

C = 1568.064

y = 2.608x²  -155.264x + 1568.064

Thus, the quadratic regression equation best fits the data set is 2.608x²  -155.264x + 1568.064 option second is correct.

Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period (typically April 10 to April 15).

a. A researcher suggests that a reason individuals wait until the last five days is that on average these individuals receive lower refunds than do early filers. Develop appropriate hypotheses such that rejection of H0 will support the researcherâs contention.
b. For a sample of 400 individuals who filed a tax return between April 10 and 15, the sample mean refund was $910. Based on prior experience a population standard deviation of Ï = $1600 may be assumed. What is the p-value?
c. At α = .05, what is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach.

Answers

Answer and Step-by-step explanation:

Solution:

Develop hypothesis:

H₀ : µ ≥ 1056

H₁ < 1056

Given:

n = 400

ẋ = 910

∂ = 1600

a = 0.05

The sampling distribution of sample means µ and standard deviation ∂ / √n.

Z = ẋ-µ /∂ / √n.

  = 910 – 1056 / 1600 /√400.

 = - 1.83

Probability: p = p(z< -1.83) = 0.033

At a = 0.05

If p value is smaller than significance level a, then hypothesis is rejected.

P < 0.05 its means H0 rejected.

Hypothesis test using critical value:

The critical value corresponding to probability of 0.05:

Z = -1.645

The rejection region, then contains all values smaller than -1.645.

If value of test statistics is within the rejection region, then null hypothesis rejected.

-1.83 < -1.645

C)  1340 days

The composite function for this question is:

(as I have proven in a previous question)

Substitute d = 22 into the function:

t(22) = 60(22) + 20
