Don't know if this is what you're looking for but here. Hope it helps.
Sara woke up at 9:00. She has dance practice at noon(12:00) it ends at 2:15. She has to meet her friend Jerry for pizza at 5:30. How much time does she have before dance, at dance, and from dance to dinner?

Kind of hard to follow but first take 9:00 to 12:00. 12-9=3 so 3 hours before dance. Next how long dance is. To get from 12:00 to 2:00 you need 2 hours. to get from 2:00 to 2:15 is 15 minutes. So dance is 2 hours and 15 minutes. After dance until dinner is going to be 2:15 to 5:30. To get to 2:00 to 5:00 is three hours. You need 15 minutes from 15 to 30. So She has 3 hours and 15 minutes from dance to dinner.

What is the equation of the line, in general form, that passes through point (-1, -1) and is parallel to the line whose equation
lara31 [8.8K]

ANSWER

x + y + 2 = 0

EXPLANATION

The given line passes through;

(-1,-1) and it is parallel to x + y = 3.

This line given to us can be rewritten as

y=-x+1

It has slope m=-1.

The line parallel to this line also has slope m=-1.

We obtain the equation of the line using the formula:

y-y_1=m(x-x_1)

We substitute the slope and the point to obtain:

y -  - 1 =  - 1(x -  - 1)

y + 1 =  - 1(x + 1)

y =  - x - 1 - 1

The equation of the line is

x + y + 2 = 0

Suppose a basketball player is practicing shooting, and has a prob-ability .95 of making each of his shots. Also assume that his
Karo-lina-s [1.5K]

Answer:

0.082

Step-by-step explanation:

Number of attempts = n = 100

Since there are only two outcomes and in-dependent of each other, the probability of missing a shot  = 1 - Probability of making each shot

p = 1 - 0.95 = 0.05

Possion Ratio (λ) = np where n is the number of events and p is the probability of the shot missing

λ = 100 x 0.05 = 5

Define X such that X = Number of misses and X ≅ Poisson (λ = 5)

P [X ≤ 2] = P [X = 0] + P [X = 1] + P [X = 2]

P [X ≤ 2] = e⁻⁵ + e⁻⁵ x 5 + e⁻⁵ x 5²/2!

P [X ≤ 2] = e⁻⁵ [1 + 5 + 5²/2!]

P [X ≤ 2] = e⁻⁵ x 12.25 = 0.082

The required probability that there are at most 2 misses in the first 100 attempts is 0.082
