Answer:
x=2,x=4
So, the 6-meter side will be 2 centimeters and the 12-meter side will be 4 centimeters in the drawing.
Step-by-step explanation:
Solve for x by using cross multiplication
6=3x
x=2
12=3x
x=4
Answer:
The y-intercept is answer b. (0, -3)
Step-by-step explanation:
To find the y-intercept, fill in x with 0.
4x + 5y = -15
4(0) + 5y = -15
0 + 5y = -15
5y = -15
y = -3
So, the y-intercept would be (0, -3).
Answer:
The two expressions are equivalent, The value of both expressions when t = 5 is 32, and The value of both expressions when t = 3 is 24
Step-by-step explanation:
4 (3 + 3) = 4(3) + 12
4(6) = 12 + 12
24 = 24
4(5 + 3) = 4(5) + 12
4(8) = 20 + 12
32 = 32
The average score is 500 points and the standard deviation is 50 points.Mean - 2 SD = 500 - 2 * 50 = 500 - 100 = 400It means that more than 400 on the standardized test is more than: Mean - 2 Standard deviations.For the Normal distribution: 100% - 2.5 % = 97.5% = 0.975.Answer: The probability that student scores more than 400 points is 0.975.
Answer:
n = 2/3
Step-by-step explanation:
3n - 22 = -20
Add 22 to both sides
-20 + 22 = 2
3n = 2
Divide both sides by 3
2 / 3 = 2/3
n = 2/3
