A campus program evenly enrolls undergraduate and graduate students. If a random sample of 4 students is selected from the program to be interviewed about the introduction of a new fast food outlet, what is the probability that all 4 students selected are undergraduate students? A. 0.0256
B. 0.0625
C. 0.16
D. 100

Answers

Answer 1

Answer:

Answer:

B. 0.0625

Step-by-step explanation:

Given that the program has graduated and undergraduates enrolled,

Let the probability of selecting a graduate = p(g)

And the probability of selecting an undergraduate = p(u)

p(g) = p(u) = 50% = 0.5

Therefore,

Probability of selecting 4 students who are undergraduates

=p(u)p(u)p(u)p(u)

= 0.5 × 0.5 × 0.5 × 0.5

= 0.0625

The right option is B

Let f(x) = x^2 + 6 and g(x) = x+8/x. Find (g ° f)(-7)

Answers

(g o f)(x)=g(f(x))

basically put f(x) for every x in g(x) or evaluate f(x) for taht given value of x and then sub that for x in g(x)
evaluate woould be easier
f(-7)=(-7)^2+6
f(-7)=49+6
f(-7)=55

sub for x in g(x)
g(55)=55+8/55
g(55)=63/55
g(55)=1.145454545454

answer would be 63/55

Short Answer: 55.145454545...
Working Out: gof(x) = (x^2 + 6) + 8/(x^2 + 6)
gof(-7) = ((-7)^2 + 6) + 8/((-7)^2 + 6)
= (49 + 6) + 8/(49 + 6)
= 55 + 8/55
= 55 + 0.145454545...
= 55.145454545...

x = 1, y = 1

Answer:

I think it is 5

Step-by-step explanation:

Which equation correctly describes the relationship between the measures of the angle and arcs formed by the intersecting secant and tangent?m∠1=1/2(mJK−mKL)
m∠1=1/2(mJK+mKL)
m∠1=1/2mJK
m∠1=mJK−mKL

Answers

Angle m∠1 if formed by a tangent and secant intersecting outside of circle. The intercepted arcs are arc LK and arc JK.
Thus;
Angle formed by Tangent and secant
=1/2(DIFFERENCE of Intercepted Arcs)
m∠1=1/2(mJK-LK)

Answer: m∠1=1/2(mJK-KL)
