Write the pair of fractions as a pair of fractions with a common denominator one fourth and two thirds

So a common denominator of 1/2 and 2/3 is 6 (sometimes the best thing to do is multiply the two denominators that are liitle numbers lol and bam that's a common denominator)
this means that (1*3) / (2*3) and (2*2) / (3*2) to get to the common denominator
the fractions become 3/6 and 4/6

Hope this helps ;)

How to solve I can’t do it

Answer:

10.94

Step-by-step explanation:

The standard deviation is calculated by using the following formula:

s=\sqrt{\frac{1}{N-1}sum(xi -x)^2}

This means that N is the total number of cases you want to take into account, times the sum of x at the ith position - x squared.

In other words, the standard deviation in your example implies the following:

26 is the first value, so i = 1, 34 is the second value, so i = 2, 18 where i = 3, and so on and so forth, until you reach the end, which is 6 (so the initial value is 1 and the last one is 6).

You're doing a sum over an iteration of all the numbers in your sample.

So applying the sum of all of the numbers, it gives us the following:

(26-28)^2+(34 - 28)^2+(18 - 28)^2 ... (41 - 28)^2

= \frac{598}{5} \\=119.6\\

The sum of all of the numbers in your sample is equal to 119.6.

Substitute into the equation once again:

s=\sqrt{119.6}

Where the square root of 119.6 is 10.93617...

Rounded to two decimal places: 10.94

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
