A study was conducted on students from a particular high school over the last 8 years. The following information was found regar
Darya [45]

Answer:

A.

SAT score = 1060

ACT score = 23.2

B.

ACT score = 36.3

Step-by-step explanation:

When the distribution is normal, we use 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.

SAT:

\mu = 999, \sigma = 199

If a student gets an SAT score that is the 62-percentile, find the actual SAT score.

This is X when Z has a pvalue of 0.62. So X when Z = 0.305.

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

0.305 = \frac{X - 999}{199}

X - 999 = 0.305*199

X = 1059.7

Rounding to the nearest whole number.

SAT score = 1060

ACT:

\mu = 21.6, \sigma = 5.2

The equivalent score is X when Z = 0.305.

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

0.305 = \frac{X - 21.6}{5.2}

X - 21.6 = 0.305*5.2

X = 23.19

So

ACT score = 23.2

B. If a student gets an SAT score of 1563, find the equivalent ACT score

Z-score for the SAT score.

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

Z = \frac{1563 - 999}{199}

Z = 2.83

Equivalent ACT:

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

2.83 = \frac{X - 21.6}{5.2}

X - 21.6 = 2.83*5.2

X = 36.3

ACT score = 36.3

A physical fitness association is including the mile run in its secondary- school fitness test. The time for this event for boys
DENIUS [597]

Answer:

0.0107 is the probability that a randomly selected boy in secondary school can run the mile in less than 325 seconds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 440 seconds

Standard Deviation, σ = 50 seconds

We are given that the distribution of time is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(run the mile in less than 325 seconds)

P(x < 325)

P( x < 325) = P( z < \displaystyle\frac{325 - 440}{50}) = P(z < -2.3)

Calculation the value from standard normal z table, we have,  

P(x < 325) = 0.0107 = 1.07\%

0.0107 is the probability that a randomly selected boy in secondary school can run the mile in less than 325 seconds.

What is the area of ABC? I need to find out how many units, please help
nikitadnepr [17]
To find the area of this figure, let's first split this into two triangles by drawing a vertical line from point B down to the bottom of the figure. We then have two triangles:

One triangle with a base of 6 units and a height of 6 units
And a second triangle with a base of 1 unit and a height of 6 units

We know that to find the area of a triangle, we must use the equation:

A= \frac{1}{2}bh

So let's solve for the first triangle:

A= \frac{1}{2}(6)(6)=18 units^{2}

The let's solve for the second triangle:

A= \frac{1}{2}(1)(6)=3 units^{2}

Now to find the total area of the figure, let's add them together:

18units^{2}+ 3units^{2} = 21units^{2}

Now we know that the area of this figure is 21 units^{2}.
