So if Miguel makes 21 dollars for five days that would give him 105 dollars. Since he spent 35 dollars a day, he would have spend 140 dollars.

Answer:

Miguel is at a loss of $35.  

Step-by-step explanation:

We are given the following information in the question:

Money spend by Miguel on each day = $35

Total numbers of days he spent money = 4

Total money spend =

\text{Money spent on each day}\times \text{Number of days money spent} = 35\times 4 = \$140

Money earned by Miguel on each day = $21

Total numbers of days he earned money = 5

Total money earned by Miguel =

\text{Money earned on each day}\times \text{Number of days money earned} = 21\times 5 = \$105

Money left with Miguel =

\text{Money earned} - \text{Money spent} = 105 - 140 = \$(-35)

Thus, Miguel is at a loss of $35.

A store has a sale with 20% off every item. When you enter the store, you receive a coupon that states that you receive an addit
mr_godi [17]
No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.

But if we just took off 30% from 100 originally, you would be at $70.00

So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.

NeX [460]

Answer:

735N

Step-by-step explanation:

According to Newton's second law;

Force = mass * acceleration due to gravity

'

Given

Mass = 75kg

Acceleration = 9.8m/s^2

Substitute into the formula;

F = 75 * 9.8

F = 735N

Hence the force required is 735N

A publisher reports that 75% of their readers own a particular make of car. A marketing executive wants to test the claim that t
Korolek [52]

Answer:

The p-value of the test is of 0.0536 > 0.02, which means that there is not sufficient evidence at the 0.02 level to support the executive's claim.

Step-by-step explanation:

A publisher reports that 75% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.

At the null hypothesis, we test if the proportion is of 75%, that is:

H_0: p = 0.75

At the alternate hypothesis, we test if the proportion is different of 75%, that is:

H_1: p \neq 0.75

The test statistic is:

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.

75% is tested at the null hypothesis:

This means that \mu = 0.75, \sigma = \sqrt{0.75*0.25}

A random sample of 280 found that 70% of the readers owned a particular make of car.

This means that n = 280, X = 0.7

Value of the test statistic:

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

z = \frac{0.7 - 0.75}{\frac{\sqrt{0.75*0.25}}{\sqrt{280}}}

z = -1.93

P-value of the test and decision:

The p-value of the test is the probability of finding a sample proportion differing from 0.75 by at least |0.7 - 0.75| = 0.05, which is P(|z| > 1.93), which is 2 multiplied by the p-value of z = -1.93.

Looking at the z-table, z = -1.93 has a p-value of 0.0268.

2*0.0268 = 0.0536.

The p-value of the test is of 0.0536 > 0.02, which means that there is not sufficient evidence at the 0.02 level to support the executive's claim.
