3/5x-5
I believe this is the expression that is described.
Answer:
5 and 18
Step-by-step explanation:
The two numbers according to Bryan are x and 3x+3. According to Lori they are x and 5x-7. So we know that x+3x+3=x+5x-7. x and x cancel out. 3 and 7 add to 10. 5x-3x=2x. So 2x=10. X=5 and the other number is 18.
Answer:
1. Adjacent 2. Vertical 3. Vertical 4. Neither 5. Adjacent
Step-by-step explanation:
Answer:
5.5
Step-by-step explanation:
Given:
18 -7x = -20.5
We can find x by subtracting 18, then dividing by the coefficient of x. (This is known as a 2-step equation.)
-7x = -38.5 . . . . . subtract 18 from both sides
x = -38.5/-7 = 5.5 . . . . .divide by -7
The value of x is 5.5.
Answer:
0.7125
Step-by-step explanation:
The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes (with probability p) in a sequence of n independent events.
The probability of getting exactly x successes in n independent Bernoulli trials = 
Total number of watches in the shipment = 50
Number of defective watches = 6
Number of selected watches = 10
Let X denotes the number of defective digital watches such that the random variable X follows a binomial distribution with parameters n and p.
So,
Probability of defective watches = 
Take n = 10 and p = 0.12
Probability that the shipment will be rejected = 

Use 
So,
Probability that the shipment will be rejected =
