P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696

Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

Answer:

P( swim | No Art and crafts) = 26/87

Step-by-step explanation:

There are total 45 children who sign up for swimming, but 12 children are sign up for both, so only 33 students are only for swimming. and there 54 children who are not sign up either one. plus 33 children ( swimming), total is 87 children who did not sign up for arts and crafts

If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?
olasank [31]
Direct variation:
y=kx

y=144 when x=12.
144=12k \\ k=\frac{144}{12} \\ k=12

y=? when x=17.
y=12 \times 17 \\
y=204

y=204 when x=17.

Can someone help with this question? thanks
Licemer1 [7]

Answer:

Regular: C & E

Irregular: A & B

Not a polygon: F & D

Step-by-step explanation:

A polygon is a close sided shape with no curves. Since F and D have curves they are not polygons. Regular polygons have side lengths which are all equal to each other. C and E are regular polygons. Irregular polygons are polygons whose sides have different values from each other. A and B are irregular.
