you rent a canoe for 5$ per hour.Your cost before the tax is added is 12.50. write and solve an equation to find the total numbe

r of hours that you need to canoe
Mathematics
1 answer:
Basile [38]2 years ago
8 0

Answer: The equation is   5x = 12.50   and  you will have the canoe for 2 and half hours or 2 hours 30 minutes.

Step-by-step explanation:

You rent the canoe for 5 dollars per hour and that can be represented by the expression  5x.  After sometime you paid $12.50 meaning that to find the number of hours that you need the canoe, we need to set 5x to equal 12.50.

5x  = 12.50    Solve for x  by divide both sides by 5.

x = 2.5

This means you will need the canoe for 2 and half hours.

kotykmax [81]

By verbal reasoning, the pair of words required can be obtained from the

synonyms of the given pair.

Correct response:

  • <u>Variable</u>; <u>supposition</u>
<h3>Analysis used for making the above selection</h3>

Prediction: A prediction is a statement indicating the result to be

expected from a trial or test, based on deductive reasoning from a

theory or hypothesis.

An explanation is a statement describing a phenomenon and is taken as

an  hypothesis.

A variable is an outcome of a test or trial, or observation.

A supposition is a held notion or belief that is similar to a hypothesis.

Therefore;

Prediction is to explanation as <u>variable</u> is to <u>supposition</u>.

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in t
andreyandreev [35.5K]

Answer:

The test statistic is c. 2.00

The p-value is a. 0.0456

At the 5% level, you b. reject the null hypothesis

Step-by-step explanation:

We want to test to determine whether or not the mean waiting time of all customers is significantly different than 3 minutes.

This means that the mean and the alternate hypothesis are:

Null: H_{0} = 3

Alternate: H_{a} = 3

The test-statistic is given by:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

Sample of 100 customers.

This means that n = 100

3 tested at the null hypothesis

This means that \mu = 3

The average length of time it took the customers in the sample to check out was 3.1 minutes.

This means that X = 3.1

The population standard deviation is known at 0.5 minutes.

This means that \sigma = 0.5

Value of the test-statistic:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{3.1 - 3}{\frac{0.5}{\sqrt{100}}}

z = 2

The test statistic is z = 2.

The p-value is

Mean different than 3, so the pvalue is 2 multiplied by 1 subtracted by the pvalue of Z when z = 2.

z = 2 has a pvalue of 0.9772

2*(1 - 0.9772) = 2*0.0228 = 0.0456

At the 5% level

0.0456 < 0.05, which means that the null hypothesis is rejected.

HELP! What is angle 5? (PICTURE INCLUDED)
lapo4ka [179]

Answer:

Angle 5 = 122

Step-by-step explanation:

Assume EB and AD intersect each other at point C

As this is the circle, four points A,B,D,E are all on the circle, so that we have:

+) m∠EBD = 1/2 measure of arc ED (small arc)

=> m∠EBD = 1/2 . 66 = 33 degree

=> m∠CBD = 33

+) m∠ADB = 1/2 measure of arc AB (small arc)

=>m∠ADB = 1/2 . 50 = 25 degree

=>m∠CDB = 25 degree

In the triangle CDB, we have total measure of three internal angles is 180 degree

=> Angle 5 + m∠CDB + m∠CBD = 180

=> Angle 5 + 25 + 33 = 180

=> Angle 5 = 180 -25 - 33 = 122 degree
