-2/9 x 4/9 is -8
so the answer is -2/9
Answer:
0% probability cab tires depths would be shallower than 0.25cm.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the probability cab tires depths would be shallower than 0.25cm.
This probability is the pvalue of Z when X = 0.25. So



has a pvalue of 0.
0% probability cab tires depths would be shallower than 0.25cm.
Answer:
Step-by-step explanation:
They are equivalent. Use the distributive property.
3(x+3)
the 3 on the outside of the parenthesis is multiplied by the variable(the letter) and thenthe constant(number) inside the parenthesis.
makes and equivalent equation 3x+9
Answer:

Step-by-step explanation:

Answer:
An adults ticket costs $9
Step-by-step explanation:
Kids:
$7
Adults:
$9
So if you add 7+7+7= 21 (kids)
then do 9+9=18(adults)
Then add them together you get 39$
