A shop rents a DVD player at $10 per day and a charged a later fee of $15 for every day it is late. If Timmy renter a DVD player

Assoli18 [71]

Answer:

$130

Step-by-step explanation:

Renting the dvd for one day costs $10.

$15 is charged for every late day .

Timmy rented the DVD player for 4 days and returned it 10 days later.

For 4 days , the amount

= $10 x 4

= $40

For the remaining six days he’ll pay

$15 x 6= $90 because he was charged the late fee .

Therefore, total amount paid by Trimmy

= $40 + $90

= $130

Trimmy paid $130

State that the triangles in each pair of similar. If so, complete the similarity statement, and find the scale factor for each o

Answer:

ΔLMN ~ ΔLFG; scale factor 7/3

Step-by-step explanation:

The ratios of side lengths, shortest to longest are ...

FG : GL : LF = 24 : 36 : 42 = 4 : 6 : 7 (reduced)

MN : NL : LM = 56 : 84 : 98 = 4 : 6 : 7 (reduced)

The side ratios are the same, so ΔLMN ~ ΔLFG. The scale factor is ...

MN/FG = 56/24 = 7/3

What would be the total length of the 2 1/4-inch barrettes if Mikayla places them end to end?

Virty [35]

2 barrettes that measure 1/4-inch each. So we need to add them together

1/4+1/4=2/4-inch
this can be simplified to 1/2-inch

Answer=1/2-inch

Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to o

Roman55 [17]

Answer:

$Range = 11-2=9$

$\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5$

$\sigma^2 =8.25 \approx 8.3$

$\sigma = \sqrt{8.25}= 2.87 \approx 2.9$

Step-by-step explanation:

Assuming this question: "Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data. 2,3,4,5,6,7,8,9,10,11 "

Solution to the problem

The range is defined as $Range = Max -Min$ and if we replace we got:

$Range = 11-2=9$

Now we can calculate the population mean with this formula:

$\mu =\frac{\sum_{i=1}^n X_i}{N}$

And if we replace we got:

$\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5$

The population variance is given by:

$\sigma^2 = \frac{\sum_{i=1}^n (X_i -\mu)^2}{N}$

And after replace we got: $\sigma^2 =8.25 \approx 8.3$

And the population standard deviation would be just the square root of the variance and we got:

$\sigma = \sqrt{8.25}= 2.87 \approx 2.9$
