The length of a rectangular room is 6.5 m in the width is 4.23 meters. What is the perimeter of the room? Report the answer with
LuckyWell [14K]
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width. 

So to solve for this you'd take 2(6.5) + 2(4.23). 
2(6.5)= 13
2(4.23)= 8.46

13+8.46= 21.46 meters. 

Based on this, the answer is C.

From a sample with n=32, the mean duration of a geyser's eruption is 3.81 minutes and the standard deviation is 1.07 minutes. Us
Damm [24]
Notice that

1.67=3.81-2\times1.07
5.95=3.81+2\times1.07

This means you are looking for

\mathbb P(1.67

Chebyshev's theorem states that for any constant k>0,

\mathbb P(|X-\mu|

which means

\mathbb P(1.67

In other words, at least 75% of the geysers will have eruptions lasting between 1.67 and 5.95 minutes. Out of 32 geysers, then, one can expect at least 24 of them to have eruptions with between these durations.

2. True/False: Adding a positive constant to each value in a quantitative data set does not affect measures of
zavuch27 [327]

Answer:

False

Step-by-step explanation:

When a constant is added to every data value in a data set?

If you add a constant to every value, the mean and median increase by the same constant. For example, suppose you have a set of scores with a mean equal to 5 and a median equal to 6. If you add 10 to every score, the new mean will be 5 + 10 = 15; and the new median will be 6 + 10 = 16.

An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole f
maria [59]

Answer:

X=49ft

Step-by-step explanation:

From the question we are told that:

Height of Eagle h=40ft

Angle of depression \theta=35\textdegree

 

Generally the trigonometry equation for diagonal X is mathematically given by

Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }

Cos\theta \textdegree=\frac{h}{X} }

X=\frac{40}{Cos 35 } }

X=48.83ft

X=49ft
