Which graph represents a linear function? (4 points)

Mathematics

leonid [27]2 years ago

Answer:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

A humanities professor assigns letter grades on a test according to the following scheme. A: Top 12% of scores B: Scores below t
RUDIKE [14]

Answer:

The minimum score required for an A grade is 88.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 77.8, \sigma = 8.5

Find the minimum score required for an A grade.

Top 12%, which is at least the 100-12 = 88th percentile, which is the value of X when Z has a pvalue of 0.88. So it is X when Z = 1.175.

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

1.175 = \frac{X - 77.8}{8.5}

X - 77.8 = 1.175*8.5

X = 87.8

Rounding to the nearest whole number

The minimum score required for an A grade is 88.

A few years​ ago, a total of 2669 thousand people lived in the metropolitan areas of Las​ Vegas, Nevada, and​ Sacramento, Califo
aniked [119]
Let's make equation for this problem. Let's say the population of LV is x, then Sacramento will be x+275 since <span>Sacramento had 275 thousand more residents than Las Vegas. Remember that their total population is 2669, so your equation will be </span>x+275 +x=2669 

If you solve this equation, you have x=1197, that is population of LV. So Sacramento is 1472.
