Answer:

5/24

Step-by-step explanation:

5 white

3 black

1 red

total number of pairs of socks: 5 + 3 + 1 = 9

On Monday there are 9 pairs. 3 pairs are black.

On Tuesday, one pair of black socks is already taken, so there are now 8 pairs of socks. 5 of those are white.

p(black on Mon. & white on Tue.) = 3/9 * 5/8 = 1/3 * 5/8 = 5/24

Black socks on monday - 3/9 or .33%.
white socks on tuesday - 5/9 or .55%

Explanation: Probability of black socks on Monday:
Total pair of socks: 1 + 3 + 5 = 9
Number of black socks on Monday: 3
3/9 = 1/3 (or divide to get a percentage)

Probability of white socks on Tuesday:
Total pair of socks: 9
Number of white socks on Tuesday: 5
5/9

What is the perimeter of rectangle EFGH?
emmasim [6.3K]
We need to identify the perimeter of the rectangle EFGH which has points as below:
G (-3, 4)
H (2, 2)
E (1, -1)
F (-4, 1)
The distance of EF, we have it:
d² = (-4-1) ² + (1--1)² = 25 + 4 = 29
d = √29
The distance from point F to point G: 
d² = (-4--3)² + (1-4)² = 1 + 9
d = √10

Hence, we can solve for the perimeter as below:
Perimeter EFGH = 2L + 2W
Perimeter EFGH = 2(√29) + 2(√10)
Perimeter EFGH = 17.09 units

The answer is the second item in the choices or the letter B which is 2√10 + 2√29 units.

At a fast food restaurant, customers are asked if they want to “round up” their bill to the next highest        dollar and donat
jarptica [38.1K]

Answer:

(a) 0.1414

(b) 0.1010

Step-by-step explanation:

(a)

The density curve is rectangular in shape.

This implies that the distribution of donations is Uniform.

(b)

Compute the probability of donations at least 85 cents as follows:

P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx

                 =\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\

Thus, the proportion of donations that are at least 85 cents is 0.1414.

(b)

Compute the probability of donations between 30 and 40 cents as follows:

P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx

                         =\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010

Thus, the probability of donations between 30 and 40 cents is 0.1010.
