Answer:
Step-by-step explanation:
J = (1/3)M + 2 <=== ur expression would be : (1/3)M + 2
A = 2J - 5
if marcella is 63....
J = (1/3 * 63) + 2 A = 2J - 5
J = 63/3 + 2 A = 2(23) - 5
J = 21 + 2 A = 46 - 5
J = 23 <== justin's age A = 41 <=== Aimee's age
Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58
Answer:
x+v/2y
Step-by-step explanation:
Move 2 to the left of y
98 divided by 7
1. 98-round to 100
7-round to 10
100 divided by 10=10
So 98 divided by 7 is about 10
That is one way
The commutative property of 9+8=17 is 8+9=17 because the commutative property states that it doesn't matter the order of the number but as long as u get the same answer.
