Answer:
q#1 Option B.2 possible solution is correct option
Q#2 option c. 1 viable solution is correct option.
Step-by-step explanation:
Q#1
y=4+3x+45
as this is a quadratic solution
and we know that when we solve a quadratic equation then it gives two possible solutions
hence option b is the correct option
Q#2
option c is correct option when we solve an quadratic equation it gives two solution one is positive and other is negative as we know that income cannot be negative
hence only one viable solution exists when we solve this
y=4+3x+45 quadratic equation

Answer:
A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known.
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
