I’m pretty sure it’s talking about the amount of water regulated to food for example how much water does gelatin have 90% why? How? Because the food produces its self with water making it absorbed and the best way the question is asking is how many __in units.

What ls 6q+m-m; use m=8and q =3
SpyIntel [72]
First of all, I see  +m  and  -m  on the left side, and I realize that when you combine those, they make zero-m.  So you can ignore them completely,
and that means that the value of 'm' has no effect on the value of that
expression.  It doesn't matter whether 'm' is  2.509  or 'm' is  8  or 'm'
is 9 hundred trillion.  Either way, the expression has the same value.

The value is   6q = 6(3) = <em>18</em> .

Solve please!!<br> equation is in the directions!!
patriot [66]
14. The equation would be -16t^2+60t+7 To find the maximum point plug in values into the equation -b/2a to find the axis of symmetry, and plug that number in for t.
b=60, a=-16
-60/-32=t=1.875
-16(1.875)^2+60(1.875)+7=63.25
Maximum point: (1.875,63.25)

Sean and Evan are college roommates who have part-time jobs as servers in restaurants. The distribution of Sean’s weekly income
Sauron [17]

Answer:

d. 0.303

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

In this question:

We want the probability of Sean having a greater income than Evan, which is the probability of the subtraction of Sean's income by Evan's income is greater than 0.

Distribution of the difference between Sean's and Evan's income:

Sean has mean 225, Evan 240. So

\mu = 225 - 240 = -15

Sean's standard deviation is of 25, Evan's of 15. So

\sigma = \sqrt{25^2+15^2} = 29.15

Probability that Sean will have a greater income than Evan in a randomly selected week:

Probability of the subtraction being greater than 0, which is 1 subtracted by the pvalue of Z when X = 0. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{0 - (-15)}{29.15}

Z = 0.51

Z = 0.51 has a pvalue of 0.695

1 - 0.695 = 0.305.

Closest to 0.303, option d.

Select the correct answer. If a six-sided die is rolled 30 times, how many times can you expect to get a 6? A. 3 B. 5 C. 6 D. 10
lidiya [134]

There are 6 numbers on a die.

The probability of rolling a 6 would be 1/6 for each time you roll the die.

Multiply the number of rolls by 1/6.

30 rolls x 1/6 probability = 5 times.

The answer is B. 5
