Answer:
there you go but im not sure . hope its helpful and good luck ;)
a. 15
b. 75
c.100
d. 105
The correct answer should be B: y = -3x + 2.
Since the line crosses the y axis at 2, your y-intercept should be 2. Using rise over run you can compare the equations to the graph. If you convert 3x to a fraction, it would be 3/1x. Since the line is going down 3 and the rise of the y = -3x + 2 is -3, that part is correct. The line also moves over 1 unit, so the run is 1, therefore the correct slope would be -3 or -3/1. Now if you combine what you have it should be y = -3x - 2, which is the same equation as B.
The greatest common factor of 42 and 96 is 6.
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.
42 = 2 x 3 x 7
96 = 2 x 2 x 2 x 2 x 2 x 3
Greatest common factor = 2 x 3 = 6

Answer:
6
Step-by-step explanation:
42 and 96
first we will find the factors of 42:
2 21
3 7
7 7
hence, factors of 42 are 2,7 and 3
then, we will find the factors of 96:
2 96
2 48
2 24
2 12
2 6
3 3
1
hence, factors of 96 are 2,2,2,2,2 and 3
Common factors are: 2 and 3
Highest common factor: 6

Answer:
1/7
Step-by-step explanation:
If a bag contains 10 white marbles, 5 green marbles, 6 yellow marbles and two marbles are drawn at random, the probability of picking a white marble and then a yellow marble means a white marble was picked first and then followed by yellow marble.
Note that the white marble that was picked first was not replaced. This is a probability question without replacement.
Probability of an event = possible outcome of event/Total outcome of event
Total outcome = total number of marbles = 10+5+6 = 21marbles
If a white marble is selected first, the probability of selecting a white marble will be 10/21.
Since the white ball wasn't replaced, the new total number of marbles will become 21-1 = 20marbles
If yellow marble was then selected out of this 20 marbles remaining, the probability of selecting the yellow marble will be 6/20 {since there are 6yellow marbles}
The probability of drawing a white marble and then a yellow marble will then give us;
10/21×6/20
= 60/420
= 6/42
= 1/7(in its simplified form)
Answer:
Mean = 5 feet 2 inches.
Step-by-step explanation:
1 feet = 12 inches
Height of Dad = 6 feet 2 inches = {(6 × 12)+2} = 74 inches
Mom is 3 inches shorter than dad = 74 - 3 = 71 inches (5 ft 11 in)
Since mom is 2 inches taller than Ivan,
Height of Ivan = 71 - 2 = 69 inches (5 ft 9 in)
Marica is 5 inches shorter than Ivan,
Height of Marica = 69 - 5 = 64 inches (5 ft 4 in)
Marica is twice as tall as Sally-Jo.
Height of Sally-Jo = 64 ÷ 2 = 32 inches (2 ft 8 in)
Hence the mean height of the Schuller family
=
= 62 inches
converting 62 inches to feet = = 5 feet 2 inches
Mean height of the Schuller family is 5 feet 2 inches.
