Match the trinomials with their factors. Tiles a2 + a − 20 a2 − 9a + 20 a2 − 8a − 20 a2 − 12a + 20 a2 − 19a − 20 Pairs Factors T

chubhunter [2.5K]

For this case we have to factorize the following trinomials as the product of two binomials.
We have then:
a2 + a - 20
(a + 5) (a-4)

a2 - 9a + 20
(a-5) (a-4)

a2 - 8a - 20
(a-10) (a + 2)

a2 - 12a + 20
(a-10) (a-2)

a2 - 19a - 20
(a-20) (a + 1)

120 adults complete a survey. 45 are men. Write the ratio of men : women in its simplest form

Blababa [14]

Answer: 3:5

Step-by-step explanation: If there are 45 men and 120 adults, that means that the other 75 are females.

45:75

But since the question asked for the simplest form, we have to divide by the GCD, which is 15. (Greatest common divisor)

45÷15:75÷15

3:5

Hope I helped!

A poll showed that 57.4% of Americans say they believe that statistics teachers know the true meaning of life. What is the proba

agasfer [191]

Answer:

The probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.

Step-by-step explanation:

Let X = number of Americans who believe that statistics teachers know the true meaning of life.

The probability of the random variable X is,

P (X) = 0.574

The event of a person not believing that statistics teachers know the true meaning of life is the complement of the event X.

The probability of the complement of an event, E is the probability of that event not happening.

$P(E^{c})=1-P(E)$

Compute the value of $P(X^{c})$ as follows:

$P(X^{c})=1-P(X)\\=1-0.574\\=0.426$

Thus, the probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
