Answer:
C
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)
EF = 
= 
= 
=
= 10 → C
Answer:
Step-by-step explanation:
1) -5 +3 = -2
When two numbers are in different sign, subtract and the result will have the bigger numbers sign. The bigger number is 5. so the result is (-2)
2) -7 - 2 = -9
When two numbers have same sign, add and the result will have the common sign
3) 122 * (-9) = - 1098
4) -6 ÷ (3/4)

= -8
Answer:
1, 2, 3, 5, 6, 10, 15, 30 there you go
Step-by-step explanation:
Answer:
Step-by-step explanation:
Group Before After
Mean 80.27 78.27
SD 12.76 12.92
SEM 3.85 3.89
N 11 11
df = 10
standard error of difference = 0.798
The mean of Before minus After equals 2.00
Given a=0.01, |t(0.005, df=10)|=3.17 (check student t table)
So 99% CI is
2±t*s
--> 2±3.17*0.798
--> -0.5 < µd< 4.5
Answer:-0.5 < µd< 4.5
