There are seven boys and five girls in a class. The teacher randomly selects three different students to answer questions. The first student is a boy, the second student is a girl, and the third student is also a girl.
7/66, 5/39, 2/9, 1/32
Answer:
7/66
Step-by-step explanation:
The probability of picking one girl would be 5/12 That is because there are 5 girls out of the 12 students, and the probability of an event occuring is:
of things you want/of things are possible
Using that same logic, the next student should be easier. We reduced the student population by 1, so we have 11 possible ways it can happen now instead of 12, so that gives us 7/11 for the probability of picking a boy as the second pick.
And lastly, using the same logic shown above, the probability of picking a girl on the third pick would be: 4/10
We are not done, though. We have the separate probabilities, but now we have to multiply then together to figure out the probability of this exact event happening:
5/12 * 7/11 * 4/10 = 140/1320
Which when reduced is: 7/66

361 cm, as the square's area
and 48 as the area for the triangle.
Are you sure those are the answer choices because I'm getting 409.
Answer:
HEY!
THE TOTAL AREA OFTHE FIGURE = AREA OF SQUARE + AREA OF TRIANGLE
= [tex]a^{2}[/tex] +( [tex]\frac{1}{2}[/tex] x b x h)
where , [tex]a^{2}[/tex] = 19 x 19 = [tex]361 cm ^{2}[/tex]
and ( [tex]\frac{1}{2}[/tex] x b x h) = ( [tex]\frac{1}{2}[/tex] x 6 x 19) = ( [tex]\frac{1}{2}[/tex] x 114) = ( [tex]\frac{114}{2}[/tex] ) = [tex]57 cm^{2}[/tex] =
∴ [tex]361 cm ^{2}[/tex] + [tex]57cm^{2}[/tex] = [tex]418cm^{2}[/tex]
∴ 418 cm²

9514 1404 393
Answer:
2 left, 5 down
Step-by-step explanation:
The translation (right, up) is the difference of the coordinates:
J'(-3, -1) -J(-1, 4) = (-3+1, -1-4) = (-2, -5)
The image has been translated left 2 and down 5.
