Answer:
A
Step-by-step explanation:
SA = πr² + πrs
r = 4.42
s = 2.61
SA = π(4.42)² + π(4.42)(2.61)
SA = 19.5364π + 11.5362π
SA = 61.34 + 36.22
SA = 97.56
The closest answer would be A.
Best of Luck!
Answer:
Option b.
Step-by-step explanation:
Given that a repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10
A matched pair hypothesis test is conducted for the difference in the means for the pairs.
If 11 pairs i.e. 22 entries are compared thenwe have degrees of freedom = 11-1 =10
b. 11 for repeated and 22 for matched
is right answer.
Note: The degrees of freedom (DF) is:
DF = n - 1
where n is the number of paired observations.
Area of the composite figure = 390 ft²
Solution:
The composite figure is splitted into two rectangles.
The image is attached below.
Length of vertical rectangle = 20 ft
Width of vertical rectangle = 7 ft
Area of vertical rectangle = length × width
= 20 × 7
Area of vertical rectangle = 140 ft²
Length of top rectangle = 25 ft
Width of top rectangle = 30 - 20 = 10 ft
Area of top rectangle = length × width
= 25 × 10
Area of top rectangle = 250 ft²
Area of the composite figure = 140 ft² + 250 ft²
Area of the composite figure = 390 ft²
2.9 is greater than 0.29 as the decimal point indicates that there are 2 1s and 9 0.1s, while 0.29 has 2 0.1s and 9 0.01s
Hello! :)
If you know the probability of an event occurring, it is easy to compute the probability that the event does not occur. If P(A) is the probability of Event A, then 1 - P(A) is the probability that the event does not occur.
So, it will be 1 - 3/8 = 5/8
5/8 or 62.5% of the probability of the event won’t occur.
Hope you understand and I hope I answered in time!
Good luck!
