The correct answer is Choice B: 0.3098.
To find the answer, you have to use a normal distribution table. Look up the percents for each z-score and subtract them to find the region between.
z = 1.92 the percent is 0.9726
z = 0.42 the percent is 0.6628
0.9726 - 0.6628 = 0.3098

IT'S THE ELLEN'S FACE FOR ME SBSJSHSSSWHSHSJSV
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
Step-by-step explanation:
making x subject in eq 1
x= (-1-9y)/-14
substituting the value of x in eq 2
17(-1-9y/-14)=7+9y
(-17-153y)/-14=7+9y
-17-153y=-98-126y
-17+98=153y-126y
81=27y
y=3
substituting this value of y in eq 1
-14x=-1-9(3)
-14x=-28
x=2
(x,y) = (2,3)
For
|a|>b
assume
a>b and a<-b
|t+4|>10
assume
t+4>10 and t+4<-10
solve each
minus 4 both sides
t>6 and t<-14
A is answer
