Answer:
C- 13.3
Step-by-step explanation:
complementary means two angles that add up to 90°. So both of the angles added together will equal 90°
4p + 2p + 9 = 90
6p = 81
p = 13.5
Answer:
(4,5)
Explanation: 9-5=4, 4+1=5
Answer:
7 inches
Step-by-step explanation:
The area of a square is given by the formula ...
A = s² . . . . . s = side length
Using the given area, you have ...
49 in² = s² . . . . . fill in given value of area
7 in = s . . . . . . . take the positive square root of both sides
The length of a side of the square is 7 inches.
Answer:
20
Step-by-step explanation:
Given that:
The study group n = 4
number of participants = 10
the sum of squares for the between-groups source of variation is 60
The objective is to determine the mean square between groups in this study
The mean square between groups in this study compares the means of the group with the sum of squares for the between-groups source (i.e the grand mean)
For this analysis;
the degree of freedom = n-1
the degree of freedom = 4 - 1
the degree of freedom = 3
Thus; the mean square between groups = 
the mean square between groups = 20
Answer:
4t miles per hour
Step-by-step explanation:
Distance refers to the amount of space an object can cover within a period of time. It can be calculated by multiplying speed and time.
Distance= speed × time
Speed is the rate of movement of an object from one place to another.
Speed= Distance/Time.
Time= distance/speed.
If Katie walks at the rate of 4miles per hour.
Her total distance in the hours is d
Total distance= speed× time
Her speed=4miles per hour
Time= t
Katie's total distance=4 miles per hour× t
=4t miles per hour
