Distance=speed x time
speed=68 miles/hour
time=4 hours
Distance=(68 miles/hour)(4 hours)=272 miles.
Answer: he traveled 272 miles.
This question is incomplete, the complete question is;
An aircraft seam requires 27 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. (Round your answers to four decimal places.)
If 25% of all seams need reworking, what is the probability that a rivet is defective?
Answer:
the probability that a rivet is defective is 0.0106
Step-by-step explanation:
Given the data in the question,
let event X represent seam fails and event B represent rivet fails.
now, 25% of all seams need reworking;
i.e P(X) = 25% = 0.25
the probability that a rivet is defective will be;
P( A ) = 1 - P( B' )²⁷
so
0.25 = 1 - P( B' )²⁷
P( B' )²⁷ = 1 - 0.25
P( B' )²⁷ = 0.75
P( B' ) =
P( B' ) = 0.9894
so
P( B ) = 1 - 0.9894
P( B ) = 0.0106
Therefore, the probability that a rivet is defective is 0.0106
Answer:
y=7x
Step-by-step explanation:
When finding the slope intercept form using 2 points, we do the following.
y=mx+b (Slope intercept from)
y=7x+b (7 is slope)
Substitute the point
7=7(1)+b
7=7+b
b=0
y=7x
Answer:
14
Step-by-step explanation:
The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Let the two odd consecutive integer be x and x+2
Let the even number between then be x+1
If the product of two consecutive odd numbers equals 55 plus ten times the even number, then;
(x)(x+2) = 55 + 10(x+1)
Expand
x² + 2x = 55 + 10x + 10
x² -8x -65 = 0
x² - 13x+5x - 65 = 0
x(x-13)+5(x- 13) = 0
(x-13) (x+5) = 0
x = 13 and -5
Since the even number is x + 1
Even number = 13 + 1 = 14
Its 114.2 because the area of the full circle is 200.96. So you take that divided by 4 +the area of the square(64)
the equation looks like this: 3.14×64÷4=50.24
then 50.24+64=114.2
