Answer: 280

Step-by-step explanation: In order to figure out how many points Kyle has in her science class, we need to find 80% of all the possible points which is 350 points.

To find 80% of 350, first write 80% as a decimal by moving the decimal point two places to the left to get .80.

Next, the word "of" means multiply, so we multiply .80 by 350.

(.80) (350) = 280

Therefore, Kylie has 280 points in he science class.

What is the surface area of the sphere below?
tatiyna

Hey there! I'm happy to help!

To find the surface area of a sphere, here is what you do.

You square the radius.

4²=16

You multiply by 4.

16×4=64

And you multiply by pi!

64×π=64π

Therefore, the surface area of the sphere is A. 64π units². It's that easy!

Now you can find the surface area of a sphere! Have a wonderful day! :D

In general, after a group makes a reservation at a restaurant, they do not show up 20% of the time. If a restaurant has 8 reserv
sashaice [31]

Answer:

P(more than 2 don't show up)=0.2031

Step-by-step explanation:

Multiplication rule for independent events:

If two events A and B are independent then the multiplication rule state that:

P(A and B)= P(A) x P(B)

Find the probability that more than two do not show up:

The probability that the reservations at the restaurant do not show up is 0.20 (=20%) and there were 8 reservations.

P(more than 2 don't show up)= 1- P(less than or equal to 2 don't show up)

= 1-( P(none show up) +P(one don't show up)+P(two don't show up)

=1- ((0.8⁸) +₈ C₁ (0.2¹)x(0.8⁷)  +₈ C₂ (0.2²)x(0.8⁶)

=1- (0.1678 +0.3355+0.2936)= 1-0.7969

P(more than 2 don't show up)=0.2031

jok3333 [9.3K]

Answer:

Kevin will take 3 hours to make all pieces.

Step-by-step explanation:

Kevin is building a large model of a soccer ball which is made of 20 hexagons and 12 pentagons.

Time taken by Kevin to measure and cut each hexagon = 6 minutes

Therefore, time taken to make 20 hexagons = 6×20 = 120 minutes

Similarly time taken by him to measure and cut a pentagon = 5 minutes

So, time taken to make 12 pentagons = 12×5 = 60 minutes

Total time taken to measure and cut 12 pentagons and 20 hexagons = 60+120 = 180 minutes

Therefore, Kevin will take 180 minutes or 3 hours to make all pieces.
