Answer:

a. 640 kernels

b. 3 pounds

Step-by-step explanation:

Total kernels = 16 * 50 = 800

White kernels = 800 * 0.2 = 160

Yellow kernels = 800 * 0.8 = 640

1 ear weight = 0.25 pounds

12 ears weight = 12 * 0.25 = 3 pounds

You go to a Christmas fair with a big Ferris wheel. The wheel has ten seats, and two people are placed on each seat. Every minut

monitta

60 people have ridden the wheel in 30 minutes

The time is given as:

$Time =30 \minutes$

The number of seats on the wheel is given as:

$Seats = 10\\$

The number of people on a seat is given as:

$People =2$

Every minute a seat exits the platform.

This means that, 2 people exit the platform every minute

So, the number (n) of people that exit the platform after 30 minutes would be:

$n =People \times Time$

This gives

$n = 2\times 30$

Multiply

$n = 60$

Hence, 60 people have ridden the wheel

A real estate agent has 14 properties that she shows. She feels that there is a 50% chance of selling any one property during a

Ratling [72]

Answer:

91.02% probability of selling more than 4 properties in one week.

Step-by-step explanation:

For each property, there are only two possible outcomes. Either it is sold, or it is not. The chance of selling any one property is independent of selling another property. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

$n = 14, p = 0.5$

Compute the probability of selling more than 4 properties in one week.

Either you sell 4 or less properties in one week, or you sell more. The sum of the probabilities of these events is decimal 1. So

$P(X \leq 4) + P(X > 4) = 1$

We want to find $P(X > 4)$ . So

$P(X > 4) = 1 - P(X \leq 4)$

In which

$P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{14,0}.(0.5)^{0}.(0.5)^{14} = 0.000061$

$P(X = 1) = C_{14,1}.(0.5)^{1}.(0.5)^{13} = 0.000854$

$P(X = 2) = C_{14,2}.(0.5)^{2}.(0.5)^{12} = 0.0056$

$P(X = 3) = C_{14,3}.(0.5)^{3}.(0.5)^{11} = 0.0222$

$P(X = 4) = C_{14,4}.(0.5)^{4}.(0.5)^{10} = 0.0611$

$P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.000061 + 0.000854 + 0.0056 + 0.0222 + 0.0611 = 0.0898$

Finally

$P(X > 4) = 1 - P(X \leq 4) = 1 - 0.0898 = 0.9102$

91.02% probability of selling more than 4 properties in one week.

a body starts its motion with speed of 10m/s and accelerates for 10s with 10 m/s. what will be the distance covered by the body

pochemuha

Answer:

600 m.

Step-by-step explanation:

We can use one of the equations of motion under constant acceleration. The one we want here is s = ut + 0.5at^2, where s = distance travelled, u = initial speed, a = acceleration and t = time.

We have: s = 10*10 + 1/2 * 10 * 10^2

= 100 + 500

= 600 m. (answer)
