The probability that the card will be a 4 or a 7 is 3/5 (A)- 1/5 plus 1/5 plus 1/5
The probability that the coin will be head both time is 1/4 (B)- 1/2 times 1/2
The probability that it will be a green and a odd number is 2/9 (B)1/3 times 2/3
Answer:
1 gallon of paint will paint 400 ft² of the wall
Unit rate = 400 ft² per gallon
Step-by-step explanation:
From the graph, when 1 gallon of paint was used, (x = 1), an area of 400 ft² of the wall was painted (y = 400).
Unit rate = y/x. That is, the amount of square feet of wall that would be painted using 1 gallon of paint.
Unit rate = 400 ft²/1 gallon = 400 ft²/gallon.
Answer:
If he got 9 out of 15 correct, he got 6 problems incorrect.
6/15 is incorrect
6/15 × 100
40 % is your answer
Answer:
The fourth graph.
Step-by-step explanation:
We have f(x + 1) so the x values will be increased by 1.
first value = 108 (when x = 1)
next value = 108 * 2/3 = 72 (when x = 2)
next = 72 * 2/ 3= 48 (when x = 3)
next = 48 * 2/3 = 32 (when x = 4)
Answer:
Both lines have the same slope.
Step-by-step explanation:
- If two lines are parallel, they have the same slope. To prove that these, lines are parallel, we have to first find out the slope between points.
y2 - y1 / x2 - x1
-3 - (-1) / 4 - 8
-2/-4
= 1/2
y2 - y1 / x2 - x1
3 - (-1) /2 - (-6)
4/8
= 1/2
Both the lines have the same slope meaning they are parallel.
