There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the di
Olin [163]

Solution: We are given:

ACT scores follow normal distribution with \mu=20.9,\sigma =4.8

SAT scores follow normal distribution with \mu=1026,\sigma=209

Now, let's find the z score corresponding to Joe's SAT score 1351.

z=\frac{x-\mu}{\sigma}

        =\frac{1351-1026}{209}

        =\frac{325}{209}

        =1.56

Therefore, Joe's SAT score is 1.56 standard deviations above the mean.

Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.

Therefore, we have:

z=\frac{x-\mu}{\sigma}

1.56=\frac{x-20.9}{4.8}

1.56 \times 4.8 = x - 20.9

7.488=x-20.9

x=20.9+7.488

x=28.388 \approx 28.4

Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24?
charle [14.2K]
We may answer the question above by dividing the expression y² - 10x + 24 with the given factor, y - 4. The division would give an answer of y - 6. Thus,

                                <span>y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.</span>
