The amount of rainfall in january in a certain city is normally distributed with a mean of 4.7 inches and a standard deviation of 0.5 .find the value of the quartile q1

4.4

Step-by-step explanation:

Quartile is 25%

From standard normal table, z-score is  -0.6745

where is mean is standard deviation which is 0.5

X=4.7-0.33725=4.36275

The first quartile is approximately 4.4

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
