Answer:
0.56
Step-by-step explanation:
0.56 Because you would have yo subtract 0.77 and 0.21
Step-by-step explanation:
12:56pm to 1:00pm = 4 min
1:00pm to 2:00pm = 1 hour
2:00pm to 2:33pm = 33 min
Total time = 4 min + 1 hour + 33 min = 1 hour 37 minutes.
Answer:
-20/-8
Step-by-step explanation:
y1 - y2
_____ (over)
x1- x2
21-41
____
18-26
-20/-8 is the slope
The amount of time spent reading email to the amount of time spent watching television is 1/12
Step-by-step explanation:
Given
Time to read email = 15 minutes
Time on television = 3 hours = 3*60 minutes = 180 minutes
Ration is the fraction between two things. In this case, the ration is from the amount of time spent reading email to the amount of time spent watching television
So,
Required ratio will be: 15/180
Simplifying => 1/12
So,
The amount of time spent reading email to the amount of time spent watching television is 1/12

Kindly check explanation
Step-by-step explanation:
H0 : μ ≥ 402
H1 : μ < 402
Test statistic :
n = 23
Sample Mean, x = 400
Variance = 900
σ = sqrt(900) = 30
Test statistic = (x - μ) ÷ σ/sqrt(n)
Test statistic = (400 - 402) ÷ 30/sqrt(23)
Test statistic = - 2 / 6.2554324
Test statistic = - 0.3197221
Test statistic = - 0.3197
Critical value :
Using the Tcritical value calculator
Tcrit; α = 0.025, df = n - 1 = 23 - 1 = 22
Tcritical = 2.074
Reject Null : if Test statistic ≤ Tcritical (left tail test)
Since ;
Test statistic ≤ Tcritical ; We reject the Null
