Answer:

should i simplify it? or factorise it?

I guess its factorise! So i m factorising!

x^2+16+64

(x)^2+2×x×8+(8)^2

(x+8)^2

=(x+8)(x+8)

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.

Somebody please answer these if your good at math and find the slope please ... due inna hour..

saveliy_v [14]

Answer:

See below

Step-by-step explanation:

Find a point on the line where it touches a gridpoint and start from there. Slope is defined as rise/run, so from that point you either go up or down for rise, and left or right for run to find another point closest where the line touches a gridpoint.
A graph with a slope that looks like \ will be negative and a slope that looks like / will be positive
