A. convert 1 hour, 18 mins, 27 secs to hours.
1+(18÷60)+27÷3,600)=1.3075 hours

26.2 miles in 1.3075= 26.2 miles / 1.3075 hr
= 26.2÷1.3075/1.3075÷1.3075
(divide the numerator and the denominator by 1.3075)

= 20.04/1

B. divide the distance by the average speed to find the time.

30 miles
---------------
20.04 mph ( which equals 1.497 hours)

so it would take 1.5 hours

Hope this helped!

Sound City sells the ClearTone-400 satellite car radio. For this radio, historical sales records over the last 100 weeks show 5

Harman [31]

Answer:

μ =2.23

$\sigma_x^2= 1.49$

$\sigma_x=1.22$

Step-by-step explanation:

Radio(x) weeks P(x)

0 5 5/100 = 0.05

1 27 27/100=0.27

2 27 27/100 = 0.27

3 27 27/100 = 0.27

4 9 9/100=0.09

5 5 5/100=0.05

We know that

Mean ,μ

$\mu =\sum x.P(x)$

μ = 0 x 0.05 + 1 x 0.27 + 2 x 0.27 + 3 x 0.27 + 4 x 0 .09 + 5 x 0.05

μ =2.23

$\sigma_x^2= \sum x^2\times P(x)-(\sum x.P(x))^2$

$\sigma_x^2= 0^2\times 0.05+ 1^2\times 0.27+ 2^2\times 0.27+ 3^2\times 0.27+ 4^2\times 0.09+5^2\times 0.05-2.23^2$

$\sigma_x^2= 1.49$

$\sigma_x= \sqrt{\sigma_x^2}$

$\sigma_x=1.22$

Which represents the reflection of f(x) = <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormula1" title="\sqrt{x}" al

Oduvanchick [21]

Answer:

The graph 1 will represent the equation.

Step-by-step explanation:

The given function is $f(x) = \sqrt{x}$ and the function will become $f(x) = \sqrt{- x}$ after a reflection over the y-axis.

Since after reflection over the y-axis the x-values of the function will change in sign and there will be no change in y-value.

Now, for x = 0, then y = 0.

For, x = - 1, then y = 1 and

For, x = - 4, then y = 2.

Therefore, graph 1 will represent the equation. (Answer)
