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.
Answer:
C. 5
Step-by-step explanation:
a triangle has 180 degrees as shown 1 angle has 88 degrees and the other 2 angles are equal basically divide 92 by 2 and you would get 46 then do that reverse thingy subtract the 1 and get 45 the divide 45 by 9 and get 5
Its C.

, 3.58?
Answer:
C. (4,28)
Step-by-step explanation:
When y = 8x - 4 ; x = 4
when u substitute x in the equation
the value of y = 28
y = (8 x 4) - 4
= 32 - 4
= <u>2</u><u>8</u><u>.</u>
As coordinates it would be (x,y) = <u>( 4,28 )</u>
