<h2>Answer= <u>42</u></h2>

Step-by-step explanation:

Greetings !

Given expression

$6 = 20 - \frac{x}{3}$

Switch sides

$20 - \frac{x}{3} = 6$

subtract 20 from both sides

$20 - \frac{x}{3} - 20 = 6 - 20$

$\frac { - x}{3} = - 14$

multiply both sides by 3

$3( \frac{ - x}{3} ) = 3( - 14)$

simplify

$- x = - 42$

divide both sides by -1.

$\frac{ - x}{ - 1} = \frac{ - 42}{ - 1} \\ x = 42$

Hope it helps!

Step-by-step explanation:

make x the subject of the formula by transposing it to the other end of the equal side.Make sure you change the sign

x/3=20-6

x/3=14

Now multiply both equations by 3 so we are only left with three

x/3(3)=14(3)

x=42

Answer:

(x-y) (a+x-y)

Step-by-step explanation:

(y-x)=-(x-y)

-a(y-x) = a(x-y)

(x-y)^2 = (x-y)(x-y)

(x-y)(a + x - y)

The Speedmaster IV automobile gets an average of 22.0 miles per gallon in the city. The standard deviation is 3 miles per gallon

aniked [119]

Answer:

91% of the time the auto will get less than 26 mpg

Step-by-step explanation:

Think of (or draw) the standard normal curve. Mark the mean (22.0). Then one standard deviation above the mean would be 22.0 + 3.0, or 25.0. Two would be 22.0 + 2(3.0), or 28.0. Finallyl, draw a vertical line at 26.0.

Our task is to determine the area under the curve to the left of 26.0.

Using a basic calculator with built-in statistical functions, we find this area as follows:

normcdf(-100, 26.0, 22.0, 3.0) = 0.9088, which is the desired probability: 91% of the time the auto will get less than 26 mpg.

47. Forming a Committee Four members from a 20-person committee are to be selected randomly to serve as chair- person, vice-chai

Svetllana [295]

Answer:

116,280 different leadership structures are possible

Step-by-step explanation:

The order is important.

For example, a Committee of John, Elisa, Laura and Rose means that John is the chairperson, Elisa the vice-chairperson, Laura the secretary and Rose the treasurer. If we exchange John and Elisa, their roles are also exchanged. This means that we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$
