Answer:To calculate the standard deviation of those numbers:

1.Work out the Mean (the simple average of the numbers)

2.Then for each number: subtract the Mean and square the result.

3.Then work out the mean of those squared differences.

4.Take the square root of that and we are done!

The expressions 10/12(245b−365) and 2/3(3b+6) represent the lengths of the diagonals of parallelogram WXYZ. For what value of b

makkiz [27]

Answer:

b = 1.52

Step-by-step explanation:

Length of diagonals of a parallelogram = $\frac{10}{12}(245b - 365)$ and $\frac{2}{3}(3b+6)$

If the given parallelogram is a rectangle,

Length of the diagonals will be equal in measure,

Therefore, $\frac{10}{12}(245b - 365)=\frac{2}{3}(3b+6)$

245b - 365 = $\frac{12}{10}\times \frac{2}{3}(3b+6)$

245b - 365 = $\frac{4}{5}(3b+6)$

5(245b - 365) = 4(3b + 6)

1225b - 1825 = 12b + 24

1225b - 12b = 24 + 1825

1213b = 1849

b = $\frac{1849}{1213}$

b = 1.52

At an electronic store, 4 phones and 3 laptops together cost $1580.62. The total cost of 2 laptops and 5 cameras is $1340.90. If

Mashutka [201]

Answer:

$2,677.72

Step-by-step explanation:

L = 3C

4P + 3L = 1,580.62

2L + 5C = 1,340.90

4P + 5L + 3C = ?

2L + 5C = 1,340.90

6C + 5C = 1,340.90

11C = 1,340.90

C = 121.90

121.90 * 3 = 365.70

L = 365.70

4P + 3L = 1,580.62

365.70 * 3 = 1,097.10

4P = 483.52

P = 120.88

C = 121.90

L = 365.70

P = 120.88

4P + 5L + 3C = ?

4(120.88) + 5(365.70) + 3(121.90) = 2,677.72
