Step-by-step explanation:
the product of both numbers is this.
just add both of them together. If im wrong, i will tell you another answer.
Answer:
Step-by-step explanation:

lets calculate the derivate of f using the chain rule:

we have that f'(1) = 4e^2, hence the equation is

or, equivalently,

0℅ decrease of 800=800
Answer:
1.4000 ;
0.0807 ;
1.69 ;
Fail to reject the Null
Step-by-step explanation:
Given :
μ = 21 minutes
x = 22.4 minutes
Sample size, n = 36
Standard deviation, s = 6
H0: μ ≥ 21
H1: μ < 21
Test statistic : (x - μ) ÷ s/sqrt(n)
Test statistic : (22.4 - 21) ÷ 6/sqrt(36)
Test statistic : 1.4 ÷ 1
Test statistic = 1.4000
Pvalue : Using the Test statistic value at α = 0.05 ; One - tail test = 0.0807
The t critical value using a critical value calculator ; DF = (n - 1) = 36 - 1 = 35 ; α = 0.05 = 1.69
Decision region :
Reject H0 if
|Test statistic| > |critical value|
1.4 < 1.69
Hence, we fail to reject H0
There isn't enough evidence they delivery time has been reduced below previous mean
Answer:
The percentage is 95.45%
Step-by-step explanation:
In this question, we are tasked with calculating the percentage of oranges weighing between a particular range.
To do this , we use the z-scores of both numbers in the range.
Mathematically, z-score can be calculated as (x - Mean)/SD
Thus we have P(3 <x < 7) = P( (3-5)/1 < z < (7-5)/1)
= P( -2 < z < 2)
Using standard score table, we have
P(-2<z<2) = 0.9545
The percentage is thus 9545/100 = 95.45
