In this question, we're comparing the two car trips that were give to us.
We know that the Jones family drove 200 miles in 5 hours
We also know that the Grant family drove 360 miles in 6 hours.
Lets see how many miles each family drives in 1 hour
Jones Family:
200 ÷ 5 = 40 mph
Grant Family:
360 ÷ 6 = 60 mph
We see that the Grant family travels more per hour than the Jones family.
This means that our comparison between the two car trips is that the Grant Family is going faster.
First, we must find what percent of 7,000 is 160.
To do this, let's do 160/7,000
160/7000 simplified is 4/75.
So, 4 out of every 75 CDs will be defective. If we want to find the probability of them all being affective, we must first do 71/75, because we subtracted the amount of defective CDs from the numerator.
Next week must multiply 71/75*71/75*71/75*71/75*71/75 to get the probability of 5 randomly selected ones being affective.
I got 1804229351/2373046875
If you divide this, you get 0.76030076354, so there is about a 76 percent chance of having all 5 randomly pulled be affective.
.Hope this helped! Comment if you have any questions!!!
Answer:
29
Step-by-step explanation:
10+2 =12
8 + 4 = 12
12 + 12 = 24
24 + 5 = 29
Answer:
a = 125°
b = 55°
c = 55°
d = 55°
e = 125°
f = 55°
Step-by-step explanation:
See the attached diagram.
The angles (x + 75)° and (2x + 25)° are the alternate angles and they are equal.
So, x + 75 = 2x + 25
⇒ x = 50
Hence, (x + 75)° = (50 + 75)° = 125°.
Now, from the given diagram it is clear that
a = (x + 75)° = (2x + 25)° = e = 125°
And, b = c = d = f = 55°
This is because, a and b are supplementary angles and their sum will be 180°.
So, a + b = 180°
⇒ 125° + b = 180°
⇒ b = 55°
So, b = c = d = f = 55° (Answer)
3*2 is 6 6*2 is 12 12*2 is 24 24*2 is 48 48*2 is 96 96*2 is 192 and 192*2 is 384
