Answer:
Hello,
le largest is <u>139</u>
Step-by-step explanation:
Since i am a lasy boy, i am going to calculate:
1+3+5+7+...+(1+2*59) there are 60 numbers
=1+3+5+..+119
=60*(1+119)/2=30*120=3600 (not enough)
4800-3600=1200 are in rest.
1200/60=20 so we add 20 to each number:
21+23+25+27+...+139=4800
Answer:
12
Step-by-step explanation:
12 times 12 is 144
Hope this helps
Answer:
B. Paired T Test
B. H0: μd = 0 and Ha: μd < 0 where μd= mean difference in blood pressure (calculated as aspirin - placebo)
Step-by-step explanation:
As the experiment is based on the difference between the results of a pair, the most appropiate test is a paired t-test.
If the 80 people group had been dividided in 2 and then compare the means for each group, it would have been a independent samples t-test.
For each pair, a variable d (for difference) is calculated and used as the outcome sample to perform the test.
Then, the null hypothesis will state that the population mean for this difference is not significantly different from 0, and the alternative hypothesis claiming it is signficant different from 0.
The sample means for the treatment group and the placebo is not individually calculated, as only the difference for each pair is used as sample in a paired t-test.
The answer would be 3d and 4d
The given ordered pair is not the solution to the equation
Step-by-step explanation:
In order to find if an ordered pair is a solution to the equation or not, we plug in the values of x and y in the equation. If the equation is true for the point then the ordered pair is the solution to the equation.
Given equation is:
Putting x=-1, y=15
The given ordered pair is not the solution to the equation
