You collect a random sample of size n from a population and calculate a 98% confidence interval. Which of the following strategies produces a new confidence interval with a decreased margin of error?

A: Use a 99% confidence level.
B: Use a 95% confidence level.
C: Decrease the sample size.
D: Use the same confidence level, but compute the interval n times. Approximately 2% of these intervals will be larger.
E: Nothing can guarantee that you will obtain a larger margin of error. You can only say that the chance of obtaining a larger interval is 0.02.

Answers

Answer:

B: Use a 95% confidence level.

Step-by-step explanation:

In the case when the random sample size from a population is collected and it determined the 98% confidence interval so that decrease the margin of error is to use a 95% confidence interval as it is needed to have a less critical value

So according to the given options, the option B is correct

Two trains, train a and train , weigh a total of 466 tons. Train A is heavier than train b. The difference of there weights is 326 tons. What is the weight of each train

Answers

Answer: A = 396 tons

B = 70 tons

Step-by-step explanation:

From the question,

Weight of A + Weight of B = 466

Weight of A - Weight of B = 326

A + B = 466 ......... i

A - B = 326 ..........ii

Subtract equation ii from I

2B = 140

B = 140/2

B = 70 tons

A = 466 - 70

A = 396 tons

you save $15 per week to purchase a bike that costs $120. write and solve an inequality to find the number of weeks you need to save to purchase the bike.

Answers

Answer:

Must save 8 weeks or more to purchase the bike.

Step-by-step explanation:15*w >= 120 where W is the number of weeks.

w >= 120/15 = 8

You need to save $15 every week for the next 8 weeks in order to purchase the bike.

What is inequality in mathematics?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is that you save $15 per week to purchase a bike that costs $120.

Assume that you need [w] weeks to save $120 for the bike.

Amount earned per week [A] = $15

Amount earned in [w] weeks [W] = $15w

Money needed [R] = $120

The inequality can be written as -

[W] ≥ [R]

We can write it as -

15w ≥ 120

Solving the inequality, we get -

15w/15 ≥ 120/15

w ≥ 8

Therefore, you need to save $15 every week for the next 8 weeks in order to purchase the bike.

How to find a side of a square when area is given?

Answers

Answer:

length =√area use this formula

The side length of square can be found by taking the square root of Area.

What are Squares?

Square are closed polygons which consist of four sides and four angles.

Each angle is 90 degree.

All the sides are of equal length.

So, by the definition of square, we know that the side lengths of square are equal.

The formula to calculate the area of the square is,

Area = a², where a is the length of one side of the square.

Let Area be given, let it be equal to A.

Then,

a² = A

Taking square root on both sides,

a = √A

Hence the side length is found by taking the square root of Area.

Answer:

105 for 3 hours

Step-by-step explanation:

First we have to find that how much he is charged for 1 hour.

140 : 4 = 35 per hour

Then we have to find how much he is charged for 3 hours by multiplying with 3.

3 x 35 = 105 per 3 hours

Answer:

£105

Step-by-step explanation:

let y represent the unknown amount

£150 = 4 hrs

y = 3 hrs

we then cross multiply

£150 x 3 hrs = y x 4 hrs

450= 4y

divide both sides by 4

450/4 = 4y/4

105 = y

Step-by-step Explanation:

11) A = 1/2(bh)

A = 1/2(14×12.1)

A = 1/2(169.4)

A = 84.7m²

12) A = 1/2(bh)

A = 1/2(16×9.4)

A = 1/2(150.4)

A = 75.2km²

A = 1/2(5.1×11)

A = 1/2(56.1)

2x−18=12
