Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation
Where
μ is the mean, x is a data of the population and is the standard deviation
In this case
Then the z-score is
Answer:
the first one is 5 times 5 times 5
the second is 7 times 7
the third is 2 times 2 times 2
Answer:
301 cm3
Step-by-step explanation:
Formula = V=πr2h
V = 3.14*4*2*12 = 301.44
Nearest whole number = 301 cm3
Start with he equation
3.5t + 4t = 4 - I did this since the walked the same amount of time and the total distanace covered was 4 miles
7.5t = 4
t = 0.53 hours
Answer:
–4(x + 3) ≤ –2 – 2x
>>.....-4x -12 ≤ -2 -2x
>> -12 +2 ≤ +2x
>> - 10 ≤ 2x
>> -5 ≤ x............>> x >= -5
