Hello from MrBillDoesMath!
Answer:
-52. None of the provided choices is correct
Discussion:
Following the usual order of math operations none of the provided answers is correct. The answer is
2*3 + 4- 62 = => * before + and -
(2*3) + 4 - 62= => 2*3 = 6
6 + 4 -62 = => 6 + 4 = 10
10 - 62 =
-52
Thank you,

Answer:
0.24315
Step-by-step explanation:
Using the z score formula to solve this question
z = (x - μ) / σ,
Such that:
x = raw score
μ = population mean
σ = population standard deviation.
From the question:
x = 3000
μ = 3550
σ = 870
z = (3000 - 3550) / 870
z = -550/870
z = -0.6962
Using the z score table as well as probability calculator(as requested in the question to find the z score)
The probability of having less than 3000 is obtained as:
P(x<3000) = 0.24315
A linear function. Sorry of it's not en
38,496 rounded to the nearest thousand is 38,000.
At first shop the 3 liters of milk cost 2995
cost per liter = cost / volume
cost per liter = 2995 / 3 L
cost per liter = 998 per liter of milk
at second shop the two liters of milk cost 1595
cost per liter = cost / volume
cost per liter = 1595 / 2 L
cost per liter = 797.5 per liter of milk
