Answer:
20 inches
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (4, 6, 30) as shown below:
Next we cross multiply. We multiply 4 and 30, and we multiply 6 and <em>x</em>.
Now, lets put the values above back into the equation:
Our last step is to divide 120 by 6 to get <em>x </em>by itself.
The answer is 20 inches.
7728/4 = 1932
see how many times the number go into each other and subtract from the next number
275, 608. The 5 is in the thousands place. Then number after it is 6, wihch is greater ten or equal to five.
The answer is 276,000
Y=-1/4x-9/2
Not sure if that’s correct but I tried
Answer:
<u>The probability of accepting the lot if none in the lot are defective is </u><u>1</u>.
Step-by-step explanation:
A large lot of crankshaft bearings is accepted if 0 out of 7 are found defective. i.e. the probability of finding a defective crankshaft is 0.
Let X be the number of defective crankshafts. We need to find the probability that X=0. We will use the binomial distribution probability formula:
<u>P(X=x) = ⁿCₓ pˣ qⁿ⁻ˣ</u>
where n = total no. of trials
x = no. of successful trials
p = probability of success
q = probability of failure (1-p)
We have n=7, p=0, q=1.
P(X=0) = ⁷C₀ (0)⁰ (1)⁷⁻⁰
P(X=0) = 1
