Angle 1 & Angle 2 are ADJACENT ANGLES as they are both next to each other.
Answer:
y = 20/3 * x + 125/3
Question 4 : 3 hours study for score 55 (?)
Step-by-step explanation:
2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.
y = mx + b
m = (75 - 55) / (5 - 2) = 20/3
b = y - mx = 55 - (20/3) * 2 = 125/3
Equation: y = 20/3 x + 125/3
Answer:
4/6 of the cake is left
Steps down below
Step-by-step explanation:
How i got the answer:
As we know that the question is asking how much, so and we also know that Susan ate 1/5 of 5/6 so the and for the equation will be 1/6. So 5/6 - 1/6 will give you the correct answer for this question.
Steps:
1: Subtract the numbers so 5/6 subtract 1/6 =4/6
Answer: 4/6

Answer: 5.37
Step-by-step explanation:
Let x = ACT scores.
Given: ACT scores have a mean of 20.8 and 9 percent of the scores are above 28. The scores have a distribution that is approximately normal.
i.e. P(X>28)=0.09 (i)
Now,
(ii)
One -tailed z value for p-value of 0.09 =1.3408 [By z-table]
From (i) and (ii)

Hence, the standard deviation = 5.37
5y = 4x + 20
- 4x + 5y = 20
