Answer:
1. 91 = 70*1.30
2a. 195= 150*1.30
2b. 210 = 150*1.40
3a. 56.70 = 156* .30
3b. 132.30 = 156-56.70
3c. 17.20 = 132.30 *0.13
3d. 149.50 = 132.30+17.20
3e. You do not have enough money, because you need $9.50 more.

24x-45y=34x
To solve for y, subtract 24x:
-45y=10x
Divide by -45:
y=-10/45x
Reduce:
y=-2/9x
To solve for x, subtract 24x:
-45y=10x
Divide by 10:
-45/10y=x
Reduce:
-9/2y=x
Answer:
3 1/2
Step-by-step explanation:
2x2x2 is 6 and 1/2 of 2 is 1 which means 6+1 is 7 so it's 3 and half
When a researcher needs to compare means for a variable grouped into two
categories based on some less-than interval variable, a t-test is appropriate.
To add, The analysis of two populations means through the use of
statistical examination is called a t-test. Small sample sizes commonly
use a t-test with two
samples. <span> What statisticians call as test statistics are
identified as t-values. A systematized value that is calculated from sample
data during a hypothesis test is called a test statistic. The procedure that
calculates the test statistic compares your data to what is expected under the </span>null
hypothesis<span>.
You already have an experience with the basic principles behind a t-test if you’ve
tried to communicated with a distracted teenager.</span>
