Answer:

Step-by-step explanation:

The Westside recreation center built a new swimming pool that measures 20 ft by 15 ft. The pool is rectangular. The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

Therefore, perimeter of the pool would be

2(20 + 15) = 70 ft

The formula for determining the area of a rectangle is expressed as

Area = length × width

Therefore, area of the pool would be

20 × 15 = 300 ft^2

The formula for determining the volume of a rectangle is expressed as

Volume = length × width × height

Given depth = 6 feet

Therefore, volume of the pool would be

20 × 15 × 6 = 1800 ft^3

The mean per capita consumption of milk per year is 140 liters with a standard deviation of 22 liters. If a sample of 233 people
salantis [7]

Answer: 0.0192

Step-by-step explanation:

Given : The mean per capita consumption of milk per year : \mu=140\text{ liters}

Standard deviation : \sigma=22\text{ liters}

Sample size : n=233

Let \overline{x} be the sample mean.

The formula for z-score in a normal distribution :

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For  \overline{x}=137.01

z=\dfrac{137.01-140}{\dfrac{22}{\sqrt{233}}}\approx-2.07

The P-value = P(\overline{x}

Hence, the probability that the sample mean would be less than 137.01 liters is 0.0192 .

6m−7)⋅4=left parenthesis, 6, m, minus, 7, right parenthesis, dot, 4, equals ¿Atorado?
mars1129 [50]

Answer:

24m - 28

Step-by-step explanation:

Given the expression (6m−7)⋅4, we are to simplify it. Using the distributive law;

A(B+C) = AB + AC [A is distributed over B and C]

For the expression (6m−7)⋅4, we will distribute 4 over 6m and -7 as shown;

(6m−7)⋅4 = 4(6m) - 4(7)

(6m−7)⋅4 = 24m - 28

Hence (6m−7)⋅4 = 24m - 28

vredina [299]

Answer: 1)2x=4 -> 4/2 = 2 so x=2

2) y=0

3) x=3

4) 2y + (3*3y) = -15

11y=-15

y = -15/11

5) 4x + 7x + 63 = 19

11x = -44

x = -4
