The difference of the fractions 8/2 and 3/5 is given as follows:

17/5.

The difference operation for this problem is defined as follows:

8/2 - 3/5.

8 is divisible by 2, with a quotient of 4, hence the subtraction can be simplified as follows:

4 - 3/5.

With a common denominator of 5, we have that 4 x 5 = 20, hence:

20/5 - 3/5.

As the fractions now have a common denominator, we can subtract the numerators while keeping the denominator constant, thus the subtraction is given as follows:

(20 - 3)/5 = 17/5.

A hypothesis that there is some sort of relationship between the variables is where scientists start their inquiry. The alternative, or null hypothesis, asserts that there is no such relationship. Although the null hypothesis may not appear fascinating, it is a crucial component of research.

The claim can be supported by either the null hypothesis or the alternative hypothesis. The null hypothesis states that the population proportion is the same as the value specified in the claim. If the null hypothesis is the assertion, then the alternative hypothesis statement is the antithesis of the null hypothesis. A hypothesis is a well-informed, logically-supported guess about the answer to a scientific question. Although it is the experiment's anticipated outcome, it does not constitute experimental proof. The information obtained may or may not be supported, depending on the information received. Simple hypotheses simply state the relationship between two independent and dependent variables. Examples: If you stay up late, you will feel fatigued the next day.

Option A: The probability of rejecting H_o, whether it's true or not, best describes the notion of the P-value of a hypothesis test.

The level of marginal significance within the hypothesis test that represents the probability of occurrence of a given event is referred to as its P-value. In order to provide the least significance at which the null hypothesis would be rejected, it is utilized as a choice for the rejection point. This signifies that the option A is correct.

The P-value is known as the probability value. It can be defined as the probability of getting a result that is either the same or more advanced than the actual observations. There is more support for the alternative hypothesis when the P-value is low.

Step-by-step explanation:

If 113 divided by a number leaves a remainder of 5, then we need to find the prime factorization of 108.

If 135 divided by a number leaves a remainder of 3, then we need to find the prime factorization of 132.

If 160 divided by a number leaves a remainder of 4, then we need to find the prime factorization of 156.

108 = 2² × 3³

132 = 2² × 3 × 11

156 = 2² × 3 × 13

The GCF of 108, 132, and 156 is common factors with lower exponent.

The second year's interest rate is 1.80%.

Compound interest is defined as Since compound interest accrues and is added to the accrued interest from earlier periods, borrowers are expected to pay interest on interest in addition to principal.

We are aware that the compound interest formula is,

A = P(1 + r/100)ⁿ.

Where A is the amount, P is the principle, r is the rate, and n is the number of years.

Given, Katy places $2000 over a three-year period in a savings account.

For the first year, the account offers compound interest at a 2.5% annual rate.

∴ A = 2000(1 + 2.5/100)¹.

A = 2000(1.025). (1.025).

A = 2050.

It now earns x% for the second year.

∴ 2050(1+x/100)² = 2124.46

(1+x/100)² =2124.46/2050

1+x/100 =√(2124.46/2050)

x/100 = √(2124.46/2050) -1

x = (√(2124.46/2050) -1)*100

x = 1.80%.

the interest is 1.80 percent

There are 5,760 ways to arrange the books on the bookshelf.

A permutation is an ordered arrangement of objects, and it can be calculated as follows:

ⁿPₓ = n! / (n - x)!

where n is the total number of objects and r is the number of objects that we are arranging.

To determine the total number of ways in which we can arrange the books on a bookshelf, we need to first calculate the total number of possible arrangements. We can do this by using the fundamental principle of counting, which tells us that the total number of possible arrangements is equal to the product of the number of ways in which each book can be arranged.

Therefore, the total number of possible arrangements can be calculated as follows:

Total number of possible arrangements = Number of ways to arrange math books × Number of ways to arrange history books × Number of ways to arrange science books

In our case, we have 4 math books, 5 history books, and 2 science books, so we can calculate the number of permutations for each type of book as follows:

Number of ways to arrange math books = ⁴P₄ = 4! / (4-4)! = 4! / 0! = 24

Number of ways to arrange history books = ⁵P₅ = 5! / (5-5)! = 5! / 0! = 120

Number of ways to arrange science books = ²P₂ = 2! / (2-2)! = 2! / 0! = 2

Now, we can substitute these values in the formula for the total number of possible arrangements:

Total number of possible arrangements = 24 × 120 × 2 = 5,760

Step-by-step explanation:

This is a family of curves represented by the equation:

y = a (x + 4) (x − 2)

Different values of the a coefficient result in different quadratic functions.

The vertex of the parabolas is halfway between the zeros, at x = -1.

y = a (-1 + 4) (-1 − 2)

y = -9a

So to find the value of a, divide the y-coordinate of the vertex by -9. For example, curve A has a vertex at (-1, -3), so the value of the a coefficient is -3 / -9 = ⅓.

A. y = ⅓ (x + 4) (x − 2)

B. y = (x + 4) (x − 2)

C. y = 2 (x + 4) (x − 2)

Probability that exactly one doesn't grow is 0.004

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

If a seed is planted, it has a 60% chance of growing into a healthy plant.

the probability of growing is 60/100 = 0.6

the probability of not growing is 1-0.6 = 0.4

eleven seeds are planted,

and 10 should grow and exactly one doesn't grow

so probability = 0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.6*0.4=0.004031
