A random number is selected from the interval [6.35, 10]. Find the probability that the number is within a distance of 0.25 from

exis [7]

Let X be a random number selected from the interval. Then the probability density for the random variable X is

$f_X(x)=\begin{cases}\dfrac1{10-6.35}=\dfrac1{3.65}\approx0.2740&\text{if }6.35\le x\le 10\\0&\text{otherwise}\end{cases}$

8 and 10 are the only even integers that fit the given criterion (6 is more than 0.25 away from 6.35), so that we're looking to compute

P(|X - 8| < 0.25) + P(|X - 10| < 0.25)

… = P(7.75 < X < 8.25) + P(9.75 < X < 10.25)

… = P(7.75 < X < 8.25) + P(9.75 < X < 10)

(since P(X > 10) = 0)

… = 0.2740 (8.25 - 7.75) + 0.2740 (10 - 9.75)

… = 0.2055

Mrs. Braddock has a bag containing 6 lipsticks, 4 eye shadows, 6 eye liners, and 5 mascaras. She will randomly choose one item f

Slav-nsk [51]

Answer:

The probability that she will not pull lipstick is 71%.

Step-by-step explanation:

The probability of an event E is the ratio of the favorable number of outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

Here,

n (E) = favorable number of outcomes

N = total number of outcomes

The contents in Mrs. Braddock's bag are:

Number of lipsticks = n (L) = 6

Number of eye shadows = n (S) = 4

Number of eye liners = n (E) = 6

Number of mascaras = n (M) = 5

Total number of items in the bag = N = 21

Consider that the probability of an event occurring is P. Then the probability of the given event not taking place is known as the complement of that event.

Complement of the given event is, 1 – P.

Compute the probability of selecting a lipstick as follows:

$P(L)=\frac{n(L)}{N}\\\\=\frac{6}{21}\\\\=\frac{2}{7}$

Compute the probability of not selecting a lipstick as follows:

$P(L^{c})=1-P(L)$

$=1-\frac{2}{7}\\\\=\frac{7-2}{7}\\\\=\frac{5}{7}$

Convert this probability into percentage as follows:

$\frac{5}{7}\times 100 = 71.4286\approx 71\%$

Thus, the probability that she will not pull lipstick is 71%.

Gerald ran out of tail on his patio. The width of the remaining area is 2 2/9 feet. the length of the remaining area is 7 feet.

tamaranim1 [39]

How much left is the simply the area.

Area = length * width

Area = 7 feet * 2 2/9

Area = 7 * 20/9 = 140/9

Area = 140/9 square feet.
