A.
Number of marbles with 'B' written on them is [ n(A)] = 6.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 6/15 = 2/5. ⬅️
B.
Number of green marbles [ n(A)] = 5.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 5/15 = 1/3 ⬅️
Answer:
1) Reflections just change the signs of the coordinates, so (1.5, -2) and (-1 and 1/2, 2) are reflections of each other. Also (1.75, -4) and (-1 and 3/4, 4)
2) From left to right: -1.75, -3/4, 1/4, 0.75, 1 and 1/2.
Remember that each 1/4 = 0.25, so this could help you work out fractions and decimals.
324 divided by 9 equals 36
Answer:
Sorry..A is right
Step-by-step explanation:
Answer:
Height=28
Step-by-step explanation:
You have to work backwards using the formula for a triangle, A=1/2bh
Plug your values in, 126=1/2 9 h
126=4.5 h
126 divided by 4.5 is 28
