F(5)=-1 because if you go over 5 on the x- axis and down 1 on the y-axis there is a point
The probability for the z-score is greater than or equal to 1.4 is 0.08076 or 8.076 %.
<h3>What is a z-score?</h3>
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The probability for the z-score is greater than or equal to 1.4 is given as
P(z ≥ 1.4) = 1 - P( z < 1.4}
P(z ≥ 1.4) = 1 - 0.91924
P(z ≥ 1.4) = 0.08076
P(z ≥ 1.4) = 8.076 %

Ok
y=mx+b
m=slope
b=y intecept
slope=-2
y=-2x+b
we are given the point (3,0)
x=3
y=0 is one solution
input
0=-2(3)+b
0=-6+b
add 6
6=b
y=-2x+6
C
Answer:
Step-by-step explanation:
twice a number is increased by 7.....let x represent the number
ur expression would be : 2x + 7
