The spinner is equally likely to land on any of the five sections.

what is the probability that the spinner lands on an even number or on the unshaded section?

a- 1/5
b-2/5
c-3/5
d-4/5

we know that

the probability of an event is the ratio of the size of the event space to the size of the sample space.

the size of the sample space is the total number of possible outcomes

the event space is the number of outcomes in the event you are interested in.

so

p=size of the event space/size of the sample space

step

find the probability that the spinner lands on an even number

size of the sample size=

size of the event space=

step

find the probability that the spinner lands on the unshaded section

size of the sample size=

size of the event space=

step

find the probability that the spinner lands on an even number or on the unshaded section

sum the probability find in step and the probability find in step

therefore

the answer is

the probability is equal to

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female
