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: 210
Step-by-step explanation: Since we are trying to find what 3/5 of a number gives you 126 You would divide 126 by 3 which equals 42 then you would add 126+42+42=210
(x-1)/5 = (4x + 2)/35
lets start off by multiplying each side by 5
(x-1) = 5(4x + 2)/35
then let's multiply both sides by 35
35(x-1) = 5(4x + 2)
now let's distribute the coefficients (5 and 35) into everything in the brackets
35 times x is 35x
35 rimes 1 is 35
5 times 4x is 20x
5 times 2 is 10
(35x - 35) = (20x + 10)
we can add 35 to both sides
35x = 20x + 45
then subtract 20x on both sides
15x = 45
then divide both sides by 15
x = 3
Answer:
X=$5000 in sales
Step-by-step explanation:
You can write an equation in slope-intercept to find an answer.
<em>y=0.2x+1000</em>, 20% commission is the slope and the base pay is the y-intercept.
Now, just plug in 2000 for y.
<em>2000</em><em>=</em><em>0.2x</em><em>+</em><em>1000,</em><em> </em>subtract 1000.
<em>1000</em><em>=</em><em>0.2x,</em><em> </em>Multiply by 5 to get x by itself.
<em>5000</em><em>=</em><em>x</em><em>.</em>
