Answer:
x=58 degrees
Step-by-step explanation:
The angle is a right angle (90 degrees)
90-32=58
The probability is given by the following formula:
Probability = number of favorable outcomes / total number of outcomes
The total number of outcomes is 10, 3 of the initial number of marbles are red and 2 of them are orange.
The probability of getting a red marble in the first draw is:
Probability = 3/10
The probability of getting an orange marble in the second draw is:
Probability = 2/10 = 1/5
the probability that he will choose a red and then an orange marble can be calculated by multiplying the probabilities that we found, then we get:
Probability = 3/10 × 1/5 = 3/150 = 1/50
Then, the answer is 1/50
18.5 you’d add 2.5 to 16 since 12.5 - 10 is 2.5 hope this helps
f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
I believe she messed up in Step 2, it wouldnt be 7/8 it would be 6/8
