527.4 + 393.8
Answer:
x-intercept (-3,0)
y-intercept (0,-9)
Step-by-step explanation:
The x-intercepts can be found by setting y to 0 and solving for x.
y=-3x-9
0=-3x-9
Add 9 on both sides:
9=-3x
Divide both sides by -3:
9/-3=x
-3=x
The x-intercept is (-3,0).
The y-intercepts can be found by setting x to 0 and solving for y.
y=-3x-9
y=-3(0)-9
y=0-9
y=-9
The y-intercept is (0,-9).
X=2y+3.5 is the awnser too this one
<em><u>ANSWER</u></em>
My answer is in the photo above
Answer:
0.81859
Step-by-step explanation:
We solve using z score method
The formula for calculating a z-score is is z = (x-μ)/σ,
where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean 0.8 pound
Standard deviation 0.25 pound
For x = 0.55 pound
z = 0.55 - 0.8/0.25
= -1
Probability -value from Z-Table:
P(x = 0.55) = 0.15866
For x = 1.3 pounds
Z = 1.3 = 0.8/0.25
= 2
Probability value from Z-Table:
P(x = 1.3) = 0.97725
The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is
P(x = 1.3) - P(x = 0.8)
0.97725 - 0.15866
0.81859.
