25% as a decimal is 0.25, and since we subtract 25% we use (1 - 0.25)=0.75.
The price of the items after discount is $248.50*0.75 = $186.38
The sales tax (5% = 0.05) is added on, so we multiply by (1 + 0.05) = 1.05
$186.375*1.05 = $195.699 = $195.70

What is the next fraction in the sequence? Simplify your answer. 3/4, 5/8, 1/2, 3/8,
erma4kov [3.2K]

Answer: 2/8.

Step-by-step explanation:

When we have this type of problem, the usual way to solve them is trying with known types of sequences.

I will start with the arithmetic sequence, where the difference between any two consecutive terms is a constant. And if we call this difference as D, we will have the recursive relation:

Aₙ = Aₙ₋₁ + D

To check if this sequence is an arithmetic sequence, we can take the first two terms and see the difference:

(5/8 - 3/4) = (5/8 - 6/8) = -1/8.

Now let's do the same, but with the second and third terms:

(1/2 - 5/8) = (4/8 - 5/8) = -1/8

The difference is the same, -1/8.

Now we can use the recursive relationship above and the last given term of the sequence to find the next one:

A₅ = A₄ + (-1/8)

A₅ = 3/8 - 1/8 = 2/8

Then the next fraction in the sequence was 2/8.

In another school a similar sample of student SAT math scores was taken. The principal of that school also believed that his stu
natali 33 [55]

Answer:

a. Type I error because the principal rejected the null hypothesis when it was true.

Step-by-step explanation:

We are given that principal of a school believed that his students scored better than the national average. For this principal collected a simple random sample of student SAT scores in math. The sample data collected had a mean student SAT score higher than 550 and the calculated P-value indicated that the null hypothesis should be rejected which means;

    Null Hypothesis, H_0 : \mu = 550 {means school's students' SAT scores is the same as the national mean score of 550}

Alternate Hypothesis, H_1 : \mu > 550 {means school's students' SAT scores is higher than the national mean score of 550}

But, in fact, the true population mean of that school's students' SAT scores is the same as the national mean score and P-value indicates that the null hypothesis should be rejected.

Hence error has been occurred.

Type I error states that Probability of rejecting null hypothesis given the fact that H_0 is true and this is the case of our question as Principal had rejected the null hypothesis based on p-value but in actual H_0 was true.
