Answer:
24 1/2 cups
Step-by-step explanation:
we can change 6 1/8 into 49/4
there are 2 cups in 1 quart
now we can set up a proportion:
2÷1 = 'c'÷ 49/4
cross-multiply to get:
49/4 × 2 = c
49/2 = c
c = 24.5
The way to do is is to write down expression, find factors of each polynomial and than cancel as many as possible. What remains is our simplified version of starting expression.
We start with this:
Now we factor every polynomial
now we can cancel fallowing factors:
5x-3, x-1 and x+5
after that we left with:
Answer:
The 95% confidence interval is "87.94, 91.86".
Step-by-step explanation:
The given values are:
Sample batches,
n = 25
Sample mean concentration,
= 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
=
=
=
Now,
The confidence interval will be:
=
On substituting the values, we get
=
=
=
Lower limit will be:
=
=
Upper limit will be:
=
=
If she has 78 ounces of rice and has to split it into 12 bags, you would divide 78/12 which equals 6.5 ounces in each bag. The answer is already a decimal:)
Answer:
73
Step-by-step explanation:
First, to get rid of the square root, square both sides of the equation to get:
y-9=64
Then, move 9 to the other side to get
y=73
