Answer:

option C

Step-by-step explanation:

if a function is linear then we know that the highest exponent is 1

so we just look for a function that doesn't have an exponent of 1 and that's option C which has an exponent of 4

A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100.

yawa3891 [41]

Answer:

The probability is 0.003

Step-by-step explanation:

We know that the average $\mu$ is:

$\mu=500$

The standard deviation $\sigma$ is:

$\sigma=100$

The Z-score is:

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

We seek to find

$P(x800)$

For P(x>800) The Z-score is:

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

$Z=\frac{800-500}{100}$

$Z=3$

The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x>800)=0.15\%$

For P(x<200) The Z-score is:

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

$Z=\frac{200-500}{100}$

$Z=-3$

The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x$

Therefore

$P(x800)=P(x800)$

$P(x800)=0.0015 + 0.0015$

$P(x800)=0.003$

What value of x is the solution of the equation 1/7+2x/3 = 15x-3/21?

lana66690 [7]

1/7+2x/3=(15x-3)/21 make all terms have a common denominator of 21

3+14x=15x-3 subtract 3 from both sides

14x=15x-6 subtract 15x from both sides

-x=-6 divide both sides by -1

x=6

*Notice the use of parentheses in this format to make it clear what the numerators and denominators are...
