Answer:
Comparing means from dependent samples.
Step-by-step explanation:
In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.
Answer:
Area = 32 square inches
Step-by-step explanation:
It is given that ,
1). an isosceles right triangle with a perimeter of 27 inches
Then the base and height are equal
2). the longest side measures 11 inches
<u>To find the smaller side</u>
Then sum of other 2 sides = 27 - 11 = 16
Base = height = 16/2 = 8 inches
<u>To find the are of triangle</u>
Area = 1/2 * Base*Height
Base = 8 inches and Height = 8 inches
Area = 1/2 * 8* 8 = 32 square inches
Answer:
,,,,,,,,,,,,,,,,,,,,,
Step-by-step explanation:
l
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
Answer:
6 units
Step-by-step explanation:
The area of a triangle is A = (b * h)/2, where b is base and h is height.
In this case, b = 6 and h = x. Plug these into the equation:
18 = (6x)/2
36 = 6x
x = 6
Thus, the answer is 6 units.
Hope this helps!
