X^2+3x-18 what are the zeros of r(x)?

Mathematics
1 answer:
Aleksandr-060686 [28]2 years ago
4 0

Answer:

Step-by-step explanation:

18 has factors of 9 and 2 or 6 and 3

Those factors must differ by 3, so 6 and 3 in some order is your answer.

(x + 6) (x - 3) = r(x)

You have to make x a value that turns the factor into 0.

x + 6 = 0

x = - 6

x - 3 = 0

x =  3

So the zeros are (3,0) and (- 6,0)

The table shows the results of a poll of 200 randomly selected juniors and seniors who were asked if they attended prom. Find th
Zielflug [23.3K]

Answer:

(a)\frac{7}{25}

(b)\frac{19}{116}

(c)\frac{28}{125}

Step-by-step explanation:

Number of juniors who attended prom,n(J)=28

Number of seniors who attended prom,n(S)=97

  • Total of those who attended prom=125

Number of juniors who did not attend prom,n(J')=56

Number of seniors who did not attend prom,n(S')=19

  • Total of those who attended prom=75
  • Total Number of students=200

(a) P (a junior who did not attend prom)

P(J')=\frac{56}{200}= \frac{7}{25}

(b)

P(Senior)=\frac{116}{200}

P ($did not attend prom$ | senior)=\frac{\text{P(seniors who did not attend prom)}}{P(Senior)} \\=\frac{19/200}{116/200} \\=\frac{19}{116}

(c)P (junior | attended prom)

P(Senior)=\frac{84}{200}

P (Junior|$ attended prom$)=\frac{\text{P(juniors who attended prom)}}{P(\text{those who attended prom)}} \\=\frac{28/200}{125/200} \\=\frac{28}{125}
