Answer:

10x² + 11x - 6

Step-by-step explanation:

The area (A) is the product of the sides, that is

A = (2x + 3)(5x - 2) ← expand using FOIL

   = 10x² - 4x + 15x - 6 ← collect like terms

   = 10x² + 11x - 6

Given the following winning percentages of the teams in a league (for a single year) compute the within-season standard deviatio
Masja [62]

Answer:

(b) 0.251

Step-by-step explanation:

1. Standard deviation equation:

SD=\sqrt{\frac{\sum\limits^N_i {(x_{i}-X)^{2}  } }{N} }

Where X is the mean of the data, and N the amount of data. Then, N=5

2. Estimate the Mean:

X=\frac{0.750+0.750+0.200+0.600+0.200}{5}=\frac{2.5}{5}=0.5\\

3. Caclulate Standard deviation:

SD=\sqrt{\frac{{(0.750-0.500)^{2}+(0.750-0.500)^{2}+(0.200-0.500)^{2}+(0.600-0.500)^{2}+(0.200-0.500)^{2}  } }{5} }

SD=\sqrt{\frac{0.315}{5} }=\sqrt{0.063}\\SD=0.251

Answer:

The answer to your question is:  9.01 x 10⁸ ice cream cones

Step-by-step explanation:

Data

# of ice cream cones = 1700

5.3 x 10 ⁵ minutes ---------- 1 year

# of ice cream cones purchased in one year = ?

                              1700  cones ---------------------  1 min

                                 x                ----------------------  5.3 x 10 ⁵ minutes

             x = (5.3 x 10 ⁵)(1700)/1 = 901 000 000 ice cream cones

In scientific notation

                                   9.01 x 10⁸ ice cream cones
