Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have
Sample size : n= 35
Let 
be the sample mean.
Now ,
Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
Answer:
x = -10
Step-by-step explanation:
Combine like terms and solve for x
3x + 8 = x - 12
3x= x - 20
2x = -20
x = -10
Answer:
x = 1/4
Step-by-step explanation:
in order to evaluate for the value of x in the equation 5( 4x + 2) + 10 = 25
we are going to open the bracket the combine the like terms together and evaluate.
solution
5 (4x + 2) + 10 = 25
20x + 10 + 10 = 25
combine the like terms
20x = 25 - 10 -10
20x = 5
divide both sides by the coefficient of x
20x/20 = 5/20
x = 1/4
therefore the value of x in the expression 5 4x + 2) + 10 = 25 is evaluated to be 1/4
Answer:
its simplest form for the question is 2:1
Set up ratios of height / shadow length:
8/6 = x/100
Cross multiply
6x = 800
Divide both sides by 6
X = 133.33 feet
The tower is 133.3 feet
