Answer:
0.2425 or 24.25%
Step-by-step explanation:
If the shipment of 400 components contains 68 defective and, we can estimate the probability of selecting a defective components as
68/400 = 0.17
Now, we have a binomial experiment of 25 trials and we want to compute the probability that more than 5 trials are “success” (defective component)
P(X>5) = 1 - P(X≤ 5)
Since
<em>1 - P(X≤ 5) = 1 - (P(X=0) + P(X=1) + P(X=3) + P(X=4) + P(X=5)</em> =
Answer:
Ted can buy the three books for $16.99 each
Step-by-step explanation:
The two books will cost a total of $59.90
$29.95 • 2 = $59.90 <u>OR</u> $29.95 + $29.95 = $59.90
The headphones and portable speaker will cost a total of $60.94
$29.99 + $30.95 = $60.94
The MP3 player and gift card will cost a total of $55.99
$35.99 + $20.00 = $55.99
The three books will cost a total of $50.97
$16.99 • 3 = $50.97 <u>OR</u> $16.99 + $16.99 + $16.99 = $50.97
I don't think you can give medals on this site, but ok
a way to simplify it is to solve for y
x+2y=8
minus x both sides
2y=8-x
divide both sides by 2
y=4-x/2
(x,y)
just sub points in (sub x values for x and see if you get the coresponding y value)
example
point (8,0)
x=8 and the resulting y should eual 0
y=4-x/2
y=4-8/2
y=4-4
y=0
yes
A. (8,0) works, (6,1) works, (4,2) works
B. (2,4) doesn't work, so this option is wrong
C. (0,8) doesn't work, so this option is wrong
D. (0,8) still , doesn't work, so this option is wrong
answer is A
Answer: There are 12 white and blue cars more than silver and red cars
Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42
Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30
How many more white and blue cars are there than silver and red cars?
n=?
n=n3-n6=42-30→n=12
Answer: There are 12 white and blue cars more than silver and red cars.
20/28 = 3x / (4x + 2)
84x = 20(4x + 2)
84x - 80x = 40
4x = 40
x = 10
so the 2 lines are equal to 30 and 42
