Answer:

18 t-shirts.

Step-by-step explanation:

Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.

The auto parts department of an automotive dealership sends out a mean of 4.34.3 special orders daily. What is the probability t
Svetlanka [38]

Answer:

P(X = 5) = 0.166

Step-by-step explanation:

Given

Mean = 4.3

x = 5

Required

Determine the probability that the order is 5

This question can be answered using Poisson distribution.

P(X = x) = \frac{\alpha ^x e^{-\alpha}}{x!}

Where

\alpha is used to represent the mean

and

\alpha = 4.3

x = 5

<em />e = 2.71828<em> ---- Euler's constant</em>

So, we have:

P(X = x) = \frac{\alpha ^x e^{-\alpha}}{x!}

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{5!}

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{5* 4 * 3 * 2 *1}

P(X = 5) = \frac{4.3^5  * 2.71828^{-4.3}}{120}

P(X = 5) = \frac{1470.08443  * 0.01356859825}{120}

P(X = 5) = \frac{19.9469850243}{120}

P(X = 5) = 0.1662248752

P(X = 5) = 0.166 <em>Approximated</em>

In a survey 9/25 students ride the bus and 19/50 walk to school. What fraction of students ride the bus or walk?
san4es73 [151]
Well since 19/50 can't be simplified you have to double 9/25 which is 18/50 so then add 18 + 19 = 37 So 18/50 + 19/50 = 37/50 so 37/50 of the students ride the bus or walk to school.

A board of length 7 divided by the quantity x minus 2 end of quantity meters was cut into two pieces. If one piece is 3 divided
bulgar [2K]

Answer:

Length of other board =\frac{4x+20}{x^{2} -4} metres

Step-by-step explanation:

Given: Length of board = \frac{7}{x-2} metres

Length of board was divided into two.

Length of one piece = \frac{3}{x+2} metres

Let l = length of the other board

Length of the other board = Length of board - Length of one piece

So, l=\frac{7}{x-2}-\frac{3}{x+2}

l=\frac{7(x+2)-3(x-2)}{(x-2)(x+2)} \\\\l=\frac{7x+14-3x+6}{x^{2} -4} \\\\l=\frac{4x+20}{x^{2} -4}

Thus, length of the other board =\frac{4x+20}{x^{2} -4} metres
