Answer:
C . Sample : 6 boy and 7 girls
Step-by-step explanation:
Data :
Boys = 150
Girls = 175
So ratio between boys and girls
175/150 = 1.67
So when boy is 6
6 ×1.667 = 7
Answer:
i would say no
Step-by-step explanation:
i would say no because quadrilateral FGIH is equal to 120 and quadrilateral SRTQ is equal to 134 and also their areas are indifferent FGIH's being 875 and SRTQ's being 1120
please let me know if this was wrong
hope this helps :) have a nice day !!
Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
No, Perry is not using the correct ratio, because 15:17 is not equivalent to 5:7
15 divided by 3 is indeed 5 but divided 17 by 3 does not give you 7, nor a whole number.
I hope this helps.
Answer:
66.6%
Step-by-step explanation:
The probability that it is blue or odd, would be the quotient between the marbles of these characteristics and the total number of marbles.
Now, we know that there are four blue marbles altogether. The odd ones, in the case of the red ones since there are eight, are the marbles 1,3,5,7 and in the blue ones the odd ones are not counted because they are already included as blue; therefore there are a total of four odd marbles. In total, between odd and blue there are eight marbles.
Which means that the probability is as follows, knowing that there are a total of 12 marbles:
8/12 = 0.666, that is, there is 66.6% chance that the marble that is drawn is blue or an odd number.
