Smart TVs have seen success in the U.S. market. During the 2nd quarter of 2015 45% of TVs sold in the United States were Smart TVs. That's an in-
crease of 11% from 2014. Choose three households and
find the probability that
a. None of the 3 households had a Smart TV
b. All 3 households had a Smart TV
c. At least 1 of the 3 households had a Smart TV
Answers
Answer:
Step-by-step explanation:
The probability of the event listed in the question are calculated as follows :
P(None has smart TV) = 0.166375 P(All have smart TV) = 0.091125P(Atleat one has a smart TV) = 0.833625The probability of having a smart TV ; P(smart) = 0.45
1.) Probability that none of the 3 households have a smart TV:
P(Smart) = 0.45
P(no smart) = 1 - P(smart) = 1 - 0.45 = 0.55
P(None) = P(no smart) × P(no smart) × P(no smart)
P(None) = 0.55 × 0.55 × 0.55 = 0.166375
2.) Probability that all 3 have Smart TVs :
P(All 3 have smart TVs) = P(smart) × P(smart) × P(smart)
P(All 3 have smart TVs) = 0.45 × 0.45 × 0.45 = 0.091125
3.) Atleast one of the 3 had a smart TV :
P(atleast 1 smart TV) = 1 - P(None)
P(atleast 1 smart TV) = 1 - 0.166375 = 0.833625
Therefore, the probability that atleast one of the 3 households has a smart TV is 0.833625

If the radius and the slant height of this right circular cone are each multiplied by 4, by what factor is the surface area multiplied?
Answers
Answer:
16
Step-by-step explanation:
Total surface area of a cone T1 = πr(r+l)
If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;
T1 = π4r(4r+4l)
T2 = 16πr(r+l)
Taking the ratio of both total area
T1/T2 = πr(r+l)/16πr(r+l)
T1/T2 = 1/16
16T1 = T2
T2 = 16 T1
Hence the total surface area is multiplied by a factor of 16

Canyon middle school has 1,250 students. 40% of these students ride the bus. How many students ride the bus?
Answers
Answer:
500 students
Step-by-step explanation:
Change the percent to a fraction in its simplest terms
Then solve 2/3×1250
Answer:
500 students ride the bus
Step-by-step explanation:
Easy:
If the total number of students is 1250 and you know 40% ride the bus all you have to do is figure out 40% of 1250. Once you get that you will get 500 people. You can use a calculator for this problem.
x/1250 = 40/100
x = number of students riding bus
Solve for x
100x = 1250*4 - after you cross mulitply
solve for x
x = 500

The balance is $ after 10 years.
Answers
Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10

Step-by-step explanation:
Hey There!
So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles
so essentially what i am saying is that
19+24=f
19+24=43
therefore
f=43
hope this helps :)
if you have anymore questions just let me know
19+24= 43

Tommy earned $ on Monday and $ on Tuesday. How many lucky bamboo plants can he buy with the total money he earned? lucky bamboo plants are 7$ each
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete. But let's assume that the amount earned on Monday is $38 while $25 was earned on Tuesday.
The total amount earned for both days will be:
= $38 + $25
= $63
Since lucky bamboo plants are $7 each, we then divide the total amount gotten by $7. This will be:
= $63 / $7
= 9
Therefore, he can buy 9 lucky bamboos
