RoseWind [281]

Answer:

Mean = 58.25

Median = 57.5

Mode = 49

Step-by-step explanation:

We are given the following data set:

55, 51, 74, 61, 67, 60, 49, 49

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{466}{8} = 58.25$

Sorted data:

49, 49, 51, 55, 60, 61, 67, 74

Mode is the entry with highest frequency.

49 appeared two times.

Mode = 49

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

$\text{Median} = \dfrac{55+60}{2} = 57.5$

All these are less than 60 seconds, which indicates that students perceive 1 minute to pass sooner than it actually has.

Find the missing side lengths. leave your answers as radicals in simplest form.

victus00 [196]

Answer:

v = 1

u = 2

Step-by-step explanation:

Given is a special right triangle with angle measures as follows:

90-60-30

The side lengths would be :

2x- x $\sqrt{3}$ -x

in the image it shows that the second side length (the one that sees angle measure 60) is $\sqrt{3}$ from this we can conclude x = 1 so:

v = 1 and

u = 2

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 300 •3m,

muminat

We have that <span>
</span>
the expression is (300)*(3^m)

for m=-1
(300)*(3^-1)---------> (300)*(1/3)=100

The value of expression at m=-1 is 100, so there were 100 visitors 1 months before the number of visitors was measured
