To find the number of big trucks, you'll subtract 2 (the given number of small trucks) from the the total number of trucks, so:.
6 - 2 = 4

Now you know that Jake has 2 small trucks and 4 large trucks, so you can check your answer:
Does 4 + 2 = 6? Yep!

If he has 6 trucks and 2 are small that would mean there are 4 left that are big.

Josh invested $12,000 in mutual funds and received a sum of $20,000 at the end of the investment period. Calculate the ROI.

tresset_1 [31]

Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

= 20,000-12,000

=8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

= 66.67%

Hence the return on investment is 66.67%!

-9 ≥ -7 is wrong as 9>7 but -9 < -7
-10 > |-10| is wrong as |-10|= 10
6 ≤ |-6| is right cause |-6| =6 and we have 6=6 or 6 ≤ |-6| is also right
0 < -13 is totally wrong

Answer:

The sample standard deviation is 393.99

Step-by-step explanation:

The standard deviation of a sample can be calculated using the following formula:

$s=\sqrt[ ]{\frac{1}{N-1} \sum_{i=1}^{N}(x_{i}-{\displaystyle \textstyle {\bar {x}}}) ^{2} }$

Where:

$s=$ Sample standart deviation

$N=$ Number of observations in the sample

${\displaystyle \textstyle {\bar {x}}}=$ Mean value of the sample

and $\sum_{i=1}^{N}(x_{i}-{\displaystyle \textstyle {\bar {x}}}) ^{2} }$ simbolizes the addition of the square of the difference between each observation and the mean value of the sample.
