Multiply
(x+a)(x+b) = x^2 + bx + ax + ab
looking at; x^2 + 10x + 24
can you see that

ab = 24
bx + ax = 10x
then
a + b = 10

use substitution: a = 10 - b

(10-b)b = 24
10b - b^2 = 24
-b^2 + 10b -24 = 0
now find the values for b using the quadratic equation. I'm on my phone so you'll have to plug the numbers in. let me know if you have any questions.

Twelve percent of the population is left handed. Approximate the probability that there are at least 20 left-handers in a school
DochEvi [55]

Answer:

Step-by-step explanation:

We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).

p = 12/100 = 0.12

number of success, x = 20

n = 200

the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)

From the binomial probability calculator,

P(x ≥ 20) = 0.84

An amusement park opens daily at 9:30 a.m. This morning the parking lot for the amusement park opened at 8:00 a.m. At 9:00 a.m.,
Eddi Din [679]

Answer:

An exponential function

Step-by-step explanation:

So let's suppose that at 9:00 am there were 132 cars. We'll call this P_0

P_{0}=132

On the next half an hour, let's say at 9:30, the number of cars trippled, this is:

P_{1}=132*3=396

the next half an hour, at 10:00 am, the number of cars trippled, this is:

P_{2}=132*3*3=1188

and finaly, at 10:30am, the number of cars trippled again, so:

P_{3}=132*3*3*3=3564

We can now see a pattern there which can be simplified as:

P(n)=P_{0}(3)^{n}

or

P(n)=132(3)^{n}

where:

P_{0}=initial number of cars

n=number of half hours after 9:00 a.m

P_{n}= number of cars after n number of half hours.

That function we found there is an exponential function, which represents an initial amount being multiplied by the same number several times.
