The sale bin in a clothing store contains an assortment of t-shirts in different sizes. There are 7 small, 8 medium, and 4 large

umka21 [38]

Answer:

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

Step-by-step explanation:

We have 7 small shirts, 8 medium shirts and 4 large shirts

Total number of shirts = 7 + 8 + 4 = 19 shirts

The probability that at least one of the first four shirts he checks is a large is given by

P(at least 1 large) = 1 - P(no large)

So first we need to find the probability that the none of the first four shirts he checks are large.

For the first check, there are 15 small and medium shirts and total 19 shirts so,

15/19

For the second check, there are 14 small and medium shirts and total 18 shirts left so,

14/18

For the third check, there are 13 small and medium shirts and total 17 shirts left so,

13/17

For the forth check, there are 12 small and medium shirts and total 16 shirts left so,

12/16

the probability of not finding the large shirt is,

P(no large) = 15/19*14/18*13/17*12/16

P(no large) = 0.352

Therefore, the probability of finding at least one large shirt is,

P(at least 1 large) = 1 - P(no large)

P(at least 1 large) = 1 - 0.352

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

Find the gross pay for 39 hours at $8.17 per hour

skelet666 [1.2K]

It is a simple multiplication problem. If you work for 39 hours, and you get paid $8.17 for every hour you work, just multiply 8.17 by 39 to get the gross pay.

8.17 x 39 = 318.63

The gross pay is $318.6.

Hope this helps =)

After reading 80% of her e-mails in her inbox, Danette still has M unread e-mails. Which of the following expressions could repr

sergey [27]

Answer:

(Choice A) 5M

Step-by-step explanation:

Let total no. of e-mails in inbox be x

Since she read 80 % of mails i.e 80 % of x

⇒ $80\% \times x$

⇒ $\frac{80}{100}\times x$

⇒ $0.8 x$

So, she read 0.8x e-mails.

So, remaining email = total e-mails - read e-mails

$=x-0.8x$

Since we are given that Danette still has M unread e-mails.

⇒ $M=x-0.8x$

⇒ $M=x(1-0.8)$

⇒ $M=x\times 0.2$

⇒ $\frac{M}{0.2}=x$

⇒ $\frac{10M}{2}=x$

⇒ $5M=x$

Thus the expression represent the number of e-mails Danette had in her inbox before she started reading is 5M.

Hence Choice A is correct.

A rectangle has an area of x^3 + 5x^2 + 5x – 2 square meters and a width of x + 2 meters. Find its length.

musickatia [10]

Answer: x^2 + 3x - 1.

Step-by-step explanation: We need to divide x^3 + 5x^2 +5x-2 by x+2. This is dividing polynomials. Divide each number by x and multiply the quotient by 2 and subtract the answer.
