If RV=w and SU=w–30, what is the value of w?

gtnhenbr [62]

Answer:

w = 60

Step-by-step explanation:

the midsegment SU is half the measure of side RV , then

SU = $\frac{1}{2}$ RV , so

w - 30 = $\frac{1}{2}$ w ( multiply through by 2 to clear the fraction )

2w - 60 = w ( subtract w from both sides )

w - 60 = 0 ( add 60 to both sides )

w = 60

if we write a 3 in front of a two-digit number, the new three digit number will be 24 more than 7 tines the origional two digit

JulsSmile [24]

Here we have a simple algebra problem, we will see that the original number was 46.

<h3>How to find the equation we need to solve:</h3>

We know that we start with a 2 digit number, it can be written as:

a*10 + b

Where a and b are decimal numbers. (from 0 to 9).

If we add a 3 "in front of it", we are adding:

3*100 + a*10 + b

And this is 24 more than 7 times the original number, so we have:

3*100 + a*10 + b = 24 + 7*(a*10 + b)

Now we can solve that:

300 + a*10 + b = 24 + a*70 + b*7

300 - 24 + a*10 - a*70 + b - b*7 = 0

276 - a*60 - b*6 = 0

276 = a*60 + b*6

This part is tricky, here you need to remember that a and b can only be integers from 0 to 9, so you can try with different integer values for b and see if a is also an integer for that value, for example taking b = 6 we get:

276 = a*60 + 6*6 = a*60 + 36

276 - 36 = a*60

240/60 = a = 4

So if b = 6, then a = 4, so both are integers in the wanted range.

From this, we can conclude that the original number is 46.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 78.2 Mbp

maks197457 [2]

Answer:

The highest speed measured was 78.2 Mbps.

n = 50

$\bar {x}=18.22$

$s= 23.87$

a)What is the difference between carrier's highest data speed and the mean of all 50 data speeds?

= 78.2 - 18.22

=59.98

b)How many standard deviations is that [the difference found in part (a)]

= $\frac{difference }{s} = \frac{59.98}{23.87}=2.5127$

c) Convert the carrier's highest data speed to a z score.

$z=\frac{78.2 - 18.22}{23.87}$

$z=2.512$

d) If we consider data speeds that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high

Yes the carrier's highest data speed is significant because it is greater than 2.
