Mathematics

4 0

Answer:

36 ways.

Step-by-step explanation:

To find the total number of ways Hailey can pair a top and a pair of jeans, we just need to multiply the number of possibilities for each item:

number of possibilities for tops: 9

number of possibilities for jeans: 4

Number of different combinations: 9 * 4 = 36

Hailey has 36 different ways of pairing a top and a pair of jeans.

PG<br> © What single decimal multiplier would you use to decrease by 1% followed by a 1% increase?
luda_lava [24]
<h3>Answer:  0.9999</h3>

Explanation:

Having a 1% increase means we go from 100% to 100%+1% = 101% which converts to the decimal form 1.01; note how you move the decimal point two spots to the left to go from 101% to 1.01

A 1% decrease means we go from 100% to 100%-1% = 99% = 0.99

Multiplying 1.01 and 0.99 leads to 1.01*0.99 = 0.9999

Since 0.9999 = 99.99%, this means we have a 100% - 99.99% = 0.01% decrease overall.

Note: the order of the decrease and increase doesn't matter. You could do the decrease first, then the increase, or vice versa.

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Y
Luda [366]

Answer:

T = 4.541

Step-by-step explanation:

We don't have the standard deviation for the population, so we use the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 4 - 1 = 3

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.98}{2} = 0.99. So we have T = 4.541

snow_lady [41]

Answer:

b. multinomial population

Step-by-step explanation:

The data is categorical and non-overlapping. That is, there are multiple options(either the student is in the Liberal Arts College, Business College or Education College), and he cannot be in more than one option.

So this is an example of a multinomial population.

The correct answer is:

b. multinomial population
