Answer:
80g
Step-by-step explanation:
Here's why:
SO you have 2:3 ratio which means the ratio for grams of butter/grams of flour has to be 2:3.
So we set up the following equation:
2/3 = 640/x (solve for x)
x= 960g
960g is what you should have to get to ratio, but the question is asking how much more you need from the initial given flour.
So you need (suppose x is the grams of flour you need)
x+880g = 960g (solve for x)
x=80g
Answer:
Step-by-step explanation:
Information provided
n=100 represent the random sample taken
X=21 represent the number of bags overfilled
estimated proportion of overfilled bags
is the value that we want to test
z would represent the statistic
Hypothesis
We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is:
(1)
And replacing the info given we got:
Answer:
Subtract One-half from both sides of the equation.
Divide both sides by 6/7
Multiply both sides by 7/6
Step-by-step explanation:
just took the question on ed
Studio = 7 yards by 4 yards
Area = 7*4 = 28 square yards.
Area of square carpet = 1 yard * 1 yard = 1 square yard
Number needed = Area of studio / Area of square carpet = 28 / 1 = 28
Number needed = 28
