Answer: i hope i helped if not im truly sorry
Solving for 9x^2 - 25 = 0
Standard form:
9x2 − 25 = 0
Solutions based on quadratic formula:
x1
= −0 − √ 02 − 4×9×(−25)
2×9
= 0 − 30 × √ 1
18
≈ −1.667
x2
= −0 + √ 02 − 4×9×(−25)
2×9
= 0 + 30 × √ 1
18
≈ 1.667
Extrema:
Min = (0, −25)

The probability of red on the second spin 1/12. the probability of blue on the second spin 1/18. the probability of not spinning cyan on either spin is 25/36.
<h3>What is probability?</h3>
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
<h3>What is probability formula?</h3>
The ratio of favorable outcomes to all possible outcomes is used as the formula to determine an event's probability. Probabilities are always in the 0 to 1 range.
Probability = Number of Favorable Outcomes / Total Number of
we know the formula of probability;
probability=favorable outcomes/total number of outcomes
so for red:
P(red) = 3/6 = 1/2
so for blue:
P(blue) = 2/6 = 1/3
so for cyan
P(cyan) = 1/6
Now totally;
P( cyan then red) = 1/6 * 1/2 = 1/12
P(cyan then blue) = 1/6 * 1/3 = 1/18
P( no cyan on 2 spins) = (1/2+1/3)* (1/2+1/3) = 5/6 * 5/6 = 25/36

Step-by-step explanation:
Train B's speed: 4/3 × 60 = 80
Combined speed = 80 + 60 = 120
Time = 240/120 = 2
Answer:
$1,700
Step-by-step explanation:
Given the following :
Period of mortgage = 25 years
Mortgage amount = $130,000
Total interest on mortgage = $380,000
Hence,
Total amount to be paid ( principal + interest) :
($130,000 + $380,000) = $510,000
Total number of months over the 25 years period:
25 × 12 = 300 months
Payment per month:
Total repayment / number of months
= $510,000 / 300
= $1,700 per month
