If you currently have $300 set aside for the trip and you're only able to save $75 a week, write an inequality representing how
algol13

Answer:

see the explanation

Step-by-step explanation:

In this problem

I will assume that the total amount required for the trip is $1,200

so

Let

x ----> the number of weeks

we know that

The number of weeks multiplied by $75 plus $300 must be at least $1,200

In this context, the term "at least" means "greater than or equal to"

so

The linear inequality that represent this problem is

75x+300\geq 1,200

Solve for x

subtract 300 both sides

75x\geq 1,200-300

75x\geq 900

Divide by 75 both sides

x\geq 12\ weeks

therefore

The minimum number of weeks you need to save is 12

mojhsa [17]

Answer:

A. Fail to reject the claim that the average math SAT score is 498 when in fact it is not 498.

Step-by-step explanation:

Type II Error:

A type II error happens when there is a non-rejection of a false null hypothesis.

In this question:

The null hypothesis is H0​:μ=498.

Since there is a type II error, there was a failure to reject the claim that the average math SAT score is 498 when in fact it is not 498, and thus, the correct answer is given by option A.
