Answer:
2
cups
Step-by-step explanation:
Given, a recipe uses 8
cups of milk for every 3
cups of oatmeal.
So, For each 8.75 cups of milk ,3.5 cups of oatmeal is required.
Or,
we can say 3.5 cups of oatmeal require 8.75 cups of milk.
Thus,
1 Cup of oatmeal will require
cups of milk.
= 2.5 cups of milk .
Thus answer is 2.5 cups, Which we can write 2 + 0.5 cups
= 2
cups (In mixed form)
Answer: 228 students
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to find the probability of students expected to score above 1850 points. It is expressed as
P(x > 1850) = 1 - P(x ≤ 1850)
For x = 1850,
z = (1850 - 1700)/75 = 150/75 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.97725
P(x > 1850) = 1 - 0.97725 = 0.02275
If 10,000 students take the exam, then the number of students you would expect to score above 1850 points is
0.02275 × 10000 = 228 students
Answer:
x = 45
Step-by-step explanation:
The average is calculated as
average = 
here the average = 50 , thus
= 50
Multiply both sides by 4
36 + 44 + 75 + x = 200
155 + x = 200 ( subtract 155 from both sides )
x = 45
Y=(x/2)+7 as an equation if that is what you are asking
Answer: B
Step-by-step explanation:
You are given the function
p(x) = √5x+7
Let p(x) = y then,
Y = √5x+7
To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,
X = √5y+7
Square both sides
X^2 = 5y + 7
Make y the subject of formula
5y = x^2 - 7
Y = ( x^2 - 7 ) / 5
the correct answer is B
