Answer:
3+4p+8t
Step-by-step explanation:
We have been given an expression:
3+2(2p+4t)
We will simplify the equation:
Firstly, we will open the parenthesis by multiplying it with the 2 given outside of the parenthesis we get:
3+4p+8t
Since, we have two variables so it can not be further solved therefore,
This is the maximum simplification of the given expression.
Answer:
19.77% of average city temperatures are higher than that of Cairo
Step-by-step explanation:
Problems of normally distributed samples are 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 question, we have that:

What percentage of average city temperatures are higher than that of Cairo?
This is 1 subtracted by the pvalue of Z when X = 21.4.



has a pvalue of 0.8023
1 - 0.8023 = 0.1977
19.77% of average city temperatures are higher than that of Cairo
Answer:
its IJ
Step-by-step explanation:
well, its obvious buddy, its asking which line is REFLECTED on the X-AXIS, which is the horizontal line across the screen. (think of the sun setting on the horizon).
so like a mirror, it should be the opposite side and not reflected across the Y-AXIS. hope this helps 6th/5th grader...
Answer:
The fraction will decrease 
Step-by-step explanation:
Let
x/y ----> the fraction
we know that
100%-50^=50%=50/100=0.50
100%-25%=75%=75/100=0.75
substitute

therefore
The percent that the fraction will decrease is equal to
