Answer:

From Least to Greatest :

-20 3/4

-15 1/2

-14 3/4

-1/4

Step-by-step explanation:

We have four fractions those of which are negative, meaning this question works a bit differently than how most least to greatest questions would work by. When dealing with negatives, you have to go backwards, or in other words, the highest number would be the least and the lowest number would be the greatest. This is due to the negative rule, that it's sort of like fighting to zero first than instead of fighting to a great and huge number. With this information, we can answer our question.

-20 3/4 is the highest number, but since we are dealing with negatives it is more far from zero, therefore making the least greatest.

Following up with -15 1/2 , its closer but not as close to the other two numbers.

Now with -14 3/4, getting closer, but not close enough as :

-1/4. This is the closest to zero, therefore it is the greatest number out of the three.

You now have your order.

12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se ¿cuál es el resultado de R(x) + S(x) ?

lesya692 [45]

Answer:

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Step-by-step explanation:

Se dan las siguientes funciones

$R(x) = -5x^2 + x - 2$

$S(x) = -x^2 - 3x$

Cuál es el resultado de R(x) + S(x) ?

Se soman los fatores en comun. Entonces:

$R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2$

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

All 10,000 California students in the beginning of 8th grade are given an entrance exam that will allow them to attend a top aca

Answer:

1.32% of students have the chance to attend the charter school.

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 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.

This year the mean on the entrance exam was an 82 with a standard deviation of 4.5.

This means that $\mu = 82, \sigma = 4.5$

a.What is the percentage of students who have the chance to attend the charter school?

Students who achieve a score of 92 or greater are admitted, which means that the proportion is 1 subtracted by the pvalue of Z when X = 92. So

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

$Z = \frac{92 - 82}{4.5}$

$Z = 2.22$

$Z = 2.22$ has a pvalue of 0.9868

1 - 0.9868 = 0.0132

0.0132*100% = 1.32%

1.32% of students have the chance to attend the charter school.
