Answer:
(x - 2) (x - 6)
Step-by-step explanation:
Factor the following:
x^2 - 8 x + 12
The factors of 12 that sum to -8 are -2 and -6. So, x^2 - 8 x + 12 = (x - 2) (x - 6):
Answer: (x - 2) (x - 6)
Answer:Tara will need to buy more 8 2/3 pint of green paint.
Step-by-step explanation:
Total amount of green paint Tara has =24 pints
Amount used to to paint a landscape =1/4 x 24= 6
Amount used To painting a clover.= 5/8 x 24= 15
Amount of paint remaining = Total paint - Amount used up in painting landscape and clover
= 24 - ( 15+ 6)
24-21
=3 pints left
Since she needs 11 2/3 pints of green paints , she will need
11 2/3 - 3 = 8 2/3 .
Therefore she will need to buy more 8 2/3 pint of green paint.
Answer:
P(X > 1.05) = 1 - 0.8413 = 0.1587 = 15.87%.
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:

Find P(X > 1.05).
This is 1 subtracted by the pvalue of Z when X = 1. So:



has a pvalue of 0.8413
So P(X > 1.05) = 1 - 0.8413 = 0.1587 = 15.87%.
