Answer:

<u>Anything less than 26, and greater than 74.</u>

Step-by-step explanation:

In normal distribution, the outlier is more than e ≈ 2.72 standard deviations above quartile 3, and e standard deviations below quartile 1. These quartiles are divisions that make up what is known as the innerquartile range(IQR). Which defines the variability of a data set given by IQR = Q3-Q1.

Given that the mean of this data is 50, and the standard deviation is 8.

Our outliers are anything less than 26, and anything greater than 74. Since outliers are anything outside the mean plus and minus the standard deviation times 3

outliers :/ = :/ mean :/  \pm

A car is driving at 100 kilometers per hour. How far does it travel in 2 seconds?
Alisiya [41]

Answer:

\frac{1}{18}\ km  or  \frac{500}{9}\ m

Step-by-step explanation:

Remember that

1 hour=3,600 seconds

so

by using proportion

\frac{100}{3,600}\frac{km}{sec} =\frac{x}{2}\frac{km}{sec} \\ \\x=2*100/3,600\\ \\x=\frac{1}{18}\ km

Convert to meters

(1,000)*(\frac{1}{18})=\frac{500}{9}\ m

A hot air balloon is flying at and altitude of 2101 feet. If the angle of depression from the pilot in the balloon to a house on
alekssr [168]
The problem is modelled as right angle triangle, shown in the diagram below

The distance between the pilot and the house is labelled as x

Using the trigonometry ratio of sine
sin(31)= \frac{opposite}{hypotenuse}
sin(31)= \frac{2010}{x}
x= \frac{2101}{sin(31)} = 4079.3 ft

Find a solution to the system. Make sure to write as a coordinate.
RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a <u>system of equations</u>.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, x=2y-4, into the value for <em>x</em> in the second equation. Now, the second equation looks like this:

2*(2y-4)+y=7

We simplify and solve for <em>y</em>:

→ 4y-8+y=7

→ 5y=15

→ y=3

Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:

→ x=2*3-4

→ x = 2

Let me know if my explanation is unclear.
