A large high school offers AP Statistics and AP Calculus Among the seniors in this school 65% take AP Statistics, 45% take AP Ca

Igoryamba

Answer:

0.8

Step-by-step explanation:

P(AP statistics) = 65%

P(AP Calculus) = 45%

P(AP statistics n AP Calculus) = 30%

Probability of AP statistics or AP Calculus but not both :

Probability of event A or B :

P(AUB) = p(A) + p(B) - p(AnB)

P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)

= 0.65 + 0.45 - 0.30

= 0.8

= 80%

A system of equations is given below. For what value(s) of x is f(x)=g(x) ?

NARA [144]

$\large{f(x) = g(x)} \\ \large{ {x}^{2} + 3x = x + 3}$

Since we are solving the quadratic equation because the highest degree in the equation is second. We arrange in the form of ax²+bx+c = 0.

$\large{ {x}^{2} + 3x - x - 3 = 0}$

Combine like terms.

$\large{ {x}^{2} + 2x - 3 = 0}$

Solve the equation by factoring.

$\large{(x + 3)(x - 1) = 0} \\ \large{x = - 3,1}$

Hence the values of x that make f(x) = g(x) are -3 and 1.

Answer

x = -3,1
