Answer:

The answer is $240

Step-by-step explanation:

You multiply 1.5 times 60 minutes and get 90, you then add 150 and 90 and you get 240.

If we collect a large sample of blood platelet counts and if our sample includes a single outlier, how will that outlier appear

Olin [163]

Answer:

D. The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.

Step-by-step explanation:

An histogram measures how many times each value appears in the set we are studying. That is, it is a frequency measure.

Suppose we have the following set:

S = {1,1,1,1,1,1, 2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,5,5,5,5,5,5,100}

1 appears 6 times. That means that when the X axis is 1, the y axis is 6.

2 appears 8 times. The means that when the X axis is 2, the y axis is 8.

...

100 appears 1 time. This means that when the X axis is 100, the y axis is 1. The X is the outlier, and it is quite far from the other values.

So the correct answer is:

D. The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.

An artist makes a structure in the shape of this given triangle.

Mumz [18]

ANSWER

$\theta =73.2 \degree$

EXPLANATION

We use the sine rule to obtain,

$\frac{ \sin( \theta) }{4} = \frac{ \sin(50 \degree) }{3.2}$

We multiply both sides by 4 to obtain,

$\sin( \theta) = \frac{ \sin(50 \degree) }{3.2} \times 4$
We take the inverse sine of both sides to get,

$\theta = \sin ^{ - 1} (0.9576)$
$\theta =73.2$
to the nearest tenth.
