So this would be F(-9)=-(-9)(2)-10(-9)-2 --------
9(2)-10(-9)-2 ----------- 18+90-2 ----------- 108-2+ 106.
So the answer to this equation is 106.

How many milliliters of 0.30%. sugar solution must you add to 75 mL of 4% sugar solution to get a 0.50% sugar solution? show you

LekaFEV [45]

We have 75 mL of 4% sugar solution.
We have to add a 30% sugar solution to make a 50% sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?

Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.

Suppose you flip 3 quarters, one at a time. What is the probability that you will

Semenov [28]

Answer:

The probability of the combination {H, T and H} is 0.125.

Step-by-step explanation:

The sample space of flipping a quarter is:

S = {H and T}

The probability of both outcomes is same, i.e. P (H) = P (T) = 0.50.

It is provided that three quarters are flipped one at a time.

The outcomes of all the three quarters are independent of each other.

Compute the probability of the combination {H, T and H} as follows:

$P(\text{H},\text{T and H}) = P(\text{H})\times P(\text{T})\times P(\text{H})$

$=0.50\times 0.50\times 0.50\\=0.125$

Thus, the probability of the combination {H, T and H} is 0.125.
