19 4-cent stamps and 3 28-cent stamps should be used.

Given that Greg needs at least $ 1.60 in stamps to mail a package, and he has 28cent stamps and 4cent stamps, and he can use no more than twenty 4cent stamps as he only has one book left, to determine how many stamps to use should be made the following calculation, through a linear function:

(0.04 x 20) + 0.28X = 1.60
0.80 + 0.28X = 1.60
0.28X = 1.60 - 0.80
0.28X = 0.80
X = 0.8 / 0.28
X = 2.85

(3 x 0.28) + 0.04X = 1.60
0.84 + 0.04X = 1.60
0.04X = 1.60 - 0.84
0.04X = 0.76
X = 0.76 / 0.04
X = 19

Therefore, 19 4-cent stamps and 3 28-cent stamps should be used.

sume that the change in daily closing prices for stocks on the New York Stock Exchange is a random variable that is normally dis

Darina [25.2K]

Answer:

0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.

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.

Normally distributed with a mean of $0.35 and a standard deviation of $0.33.

This means that $\mu = 0.35, \sigma = 0.33$ .

What is the probability that a randomly selected stock will close up $0.75 or more?

This is 1 subtracted by the p-value of Z when X = 0.75. So

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

$Z = \frac{0.75 - 0.35}{0.33}$

$Z = 1.21$

$Z = 1.21$ has a p-value of 0.8869.

1 - 0.8869 = 0.1131

0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.

What is the equation of the line that passes through the point (3,3) and has a slope of 0

Flauer [41]

Answer:

y=3

Step-by-step explanation:

Using slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. Plugging in 0 for the slope, y=b. Since y=3 in the point (3,3), 3=b. Therefore, the line is y=3.
