ACT mathematics score for a particular year are normally distributed with a mean of 28 and a standard deviation of 2.4 points
kompoz [17]

Answer:

a.   0.1587

b.  0.8849

c.  0.1814

Step-by-step explanation:

a. Given that \mu=28, \ \ \sigma=2.4

-The probability a randomly selected score is greater than 30.4 is calculated as:

P(X>30.4)=1-P(X30.4)=1-P(z

Hence, the probability of a score greater than 30.4 is 0.1587

b. Given that \mu=28, \ \ \ \sigma=2.4

The probability a randomly selected score is less than 32.8 is calculated as:

P(X

Hence, the probability that a randomly selected score is less than 32.8 is 0.8849

c. The probability that a score is between 25.6 and 32.8 is calculated as follows:

P(25.6

Hence, the probability is 0.1814

Find the solutions of 6(2-7x)+x(7x-2=0)
azamat
6(2-7x)+x(7x-2)=0

Use distributive property: a(b - c) = ab - ac

(6)(2)-(6)(7x)+(x)(7x)-(x)(2)=0\\\\12-42x+7x^2-2x=0\\\\7x^2-44x+12=0\\\\7x^2-42x-2x+12=0\\\\7x(x-6)-2(x-6)=0\\\\(x-6)(7x-2)=0\iff x-6=0\ \vee\ 7x-2=0\\\\x-6=0\ \ \ |+6\\\\x=6\\\\7x-2=0\ \ \ |+2\\\\7x=2\ \ \ |:7\\\\x=\dfrac{2}{7}

If we collect a large sample of blood platelet counts and if our sample includes a single​ outlier, how will that outlier appear
Mademuasel [1]
That outlier will appear as a single blip of data, but it will be far away from the central part of the histogram. It will not be that visible if there is a lot of data, since 1 outlying data point will just show a very low height compared to the central data near the mean/median/mode, where there will be higher frequencies and higher bars of data.

If these are the choices:
<span>A.The outlier will appear as a tall bar near one side of the distribution.
B.The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.
C.Since a histogram shows​ frequencies, not individual data​ values, the outlier will not appear.​ Instead, the outlier increases the frequency for its class by 1.
D.The outlier will appear as the tallest bar near the center of the distribution.
</span>
Then the most accurate answer will be B, since it's just a single value with a bar corresponding to a frequency of 1.
