Any help I rlly don’t get this and I need help
RUDIKE [14]
The number of favorable outcomes is the the number of the outcome she wants. She wants a silver car. In her table, 36 cars are silver.
a. 36

The total number of trials is the sum of the all numbers of cars.
12 + 9 + 32 + 42 + 36 + 1
b. 132

The experimental probability of an event is the number of desired outcomes divided by the total number of outcomes.
c. p(silver car) = 36/132 = 3/11

d.
An event takes place, and there are only two possible outcomes.
If the probability of one event happening is x, then the probability of the other event happening is 1 - x.

Think of this situation as only two possible outcomes.
Either a silver car passes or a non-silver car passes.
The probability of a silver car passing is 3/11.
Then the probability of a non-silver car passing is 1 - 3/11.
1 - 3/11 = 11/11 - 3/11 = 8/11

Because of her work schedule, Molly Kay plans to take classes at 8:00, 10:00, and 11:00. Five courses that fit her program are o
pychu [463]

Answer: There are 90 different schedules are possible for Molly Kay.

Step-by-step explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

^{5}C_1\times ^9C_1\times ^2C_1\\\\=5\times 9\times 2\\\\=45\times 2\\\\=90

Hence, there are 90 different schedules are possible for Molly Kay.

Let f(x) = x^2 - 11x - 60.<br> Solve for f(x) using factoring.
Alona [7]
F(x) = X^2 - 11x - 60
Two terms that multiply to -60 and add to -11 so...
F(x) = (X - 15) (x + 4)
Your x-intercepts would be 15 and -4.
