Answer:
0.02275
Step-by-step explanation:
We use this z score formula to solve for this question
z-score is is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
From the above question,
x = 77
μ = 75
σ = 7
number of samples = 49
Hence, the z score = 77 - 75/ (7/√49)
= 2/(7/7)
= 2/1
= 2
Hence, the z score = 2
Using the z table to find probability
P(x<77) = 0.97725
P(x>77) = 1 - P(x<77)
= 1 - 0.97725
= 0.02275
Therefore, the probability that the same mean will be larger than 77 years
is 0.02275
F(x) = x^2 - 6x + 4 {-3, 0, 5} (x, y) x is the domain, y is the range.
plug in the domain numbers into the equation to find the range.
y = x^2 - 6x + 4
y = -3^2 - 6(-3) + 4
y = 9 - (-18) + 4
y = 9 + 18 + 4
y = 31 (-3, 31)
y = x^2 - 6x + 4
y = 0^2 - 6(0) + 4
y = 0 - 0 + 4
y = 4 (0, 4)
y = x^2 - 6x + 4
y = 5^2 - 6(5) + 4
y = 25 - 30 + 4
y = -1 (5, -1)
c. {-1, 4, 31}
hope this helped, God bless!

Answer:
She can make 27 bags
2 pieces of candy is left over
Step-by-step explanation:
She has 245 Chocolate Twisters.
she puts 9 Chocolate Twisters in each treat bag,
1 bag hold 9 chocolates
9 chocolates = 1 bag
So 245 chocolates in how many bags
Divide 245 by 9
use long division
2 7 -----------> Quotient
------------------------------------
9 245
18 (subtract it)
-------------------------
65
63 (subtract it)
----------------------------
2 -----------> remainder
She can make 27 bags
2 pieces of candy is left over
4y^2 + 16y
You distribute the 2y into the 2y+8
