Explanation:
2 - (-3) = 5
Answer:
Null hypothesis is rejected. Standard deviation is > 8 miles per hour
Step-by-step explanation:
σ [Population standard deviation] = 8 , s [sample standard deviation] = s
n [no of items] = 8
H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8
χ2 = (n - 1) . s^2 / σ^2
= 49 x (10.5)^2 / 82 = 5402.25 / 64
χ2 = 84.410
df [degree of freedom] = n -1 = 50 - 1 = 49
P value (χ^2 49 > 84.410) = 0.00125
p = 0.0013
p < α ie 0.05
So, H0 is rejected
Hence we state that standard deviation is > 8 miles per hpur

Answer:
10
Step-by-step explanation:
The acronym PEMDAS is helpful when learning order of operations. It stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction which is the order in which you solve an equation. For this set of numbers there are no parenthesis or exponents so you would start by multiplying 3*2=6 Then add the 8 to the 6 and you get 14 Subtract the 4 and the answer is 10
Answer:
The product will always be less than the factor.
Step-by-step explanation:
When you multiply numbers less than 1, you get a smaller factor each time.
