Answer: The first one. 2 to the 20th power over 3 to the 8th power
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
because -8+3=-5, and -8-(-3) has to cancel out the 2 negatives which will change it to -8+3 which makes it the same question
Using cross multiplication
(x-4)(x+2)=0
x-4=0
x+2=0
Thus x=4,-2
Answer:
65.5
Step-by-step explanation:
Using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/√n
The Zcritical value at 95% = 1.96
Hence,
Margin of Error = 1.96 * 2.5/√60
Margin of Error = 1.96 * 0.3227486
Margin of Error = 0.6326
Lower boundary = 65.5 - 0.6326 = 64.867
Upper boundary = 65.5 + 0.6326 = 66.133
(64.867 + 66.133) / 2
The reflection of point S across the y-axis is point V. The reflection of point Q across the x-axis and the y-axis is point V, whose coordinates are (-5,-5.5).
