PLEASE include a picture so we can answer!!!
100* 1/4 =
100/4 =
25 km
1/4 is quarter, it is like saying divide 100 km into 4 parts, what is the measure of each part.
Answer:
idk sorry
Step-by-step explanation:
Answer: the probability that no sections receive a hard test is 0.1022
Step-by-step explanation:
Given that;
total number of exams = 20
hard exams = 8
reasonable = 7
easy exam = 5
so total exams that are bot hard = 7 + 5 = 12
we will make use of the probability mass function of hyper geometric distribution;
so the probability that no section of the received a hard test can be determined as follows;
P( x=0; N=20, n=4, k=8 ) = [ ⁸C₀ × ²⁰⁻⁸C₄₋₀ ] / ²⁰C₄
= [1 × ¹²C₄ ] / ²⁰C₄
= [1 × (12!/(4!×(12-4)!) ] / (20!/(4!×(20-4)!)
= [1 × 495 ] / 4845
= 495 / 4845
= 0.1022
Therefore the probability that no sections receive a hard test is 0.1022
The slope-intercept form of a line is:
y=mx+b, where m=slope and b=y-intercept
First find the slope, which is the change in y divided by the change in x, mathematically:
m=(y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are any two points...
m=(-5--5)/(7-2)
m=0/5
m=0, so this line has zero slope, thus it is a horizontal line of the form:
y=k, where k is the constant value of y, in this case y=-5 so
y=-5
