4 - 5t >= 2
-5t >= -2
5t<= 2
t <= 2/5
Answer:
Step-by-step explanation:
Use the ordered pairs to determine the correct function
<u>Point (0, 3)</u>
- x = 0 and y = 3- options A or D, the others result in y = -3
<u>Point (1, 8)</u>
x = 1, y = 8 - option A.
- 2*1^2 - 3*1 + 3 = 2 - incorrect
<u>It leaves us with option D</u>
- 2*1^2 +3*1 + 3 = 8 - correct
<u>Check other two pairs as well:</u>
- 2*2^2 + 3*2 + 3 = 17
- 2*3^2 + 3*3 + 3 = 30
This confirms option D is correct
Answer:
2
Step-by-step explanation:
Given
See attachment for chart
Required
Number of off days
To do this, we simply calculate the expected value of the chart.
This is calculated as:
Where
x = days
f = chances
So, we have:
Answer:
The scale factor James used to go from Rectangle N to Rectangle P is 3 or 3:1
Step-by-step explanation:
Given that Rectangle N has an area of 5 square units. That is An = 5
Rectangle P has an area of 45 square units. That is Ap = 45
The scale factor James used to go from Rectangle N to Rectangle P will be in the form
An/Ap = N^2/P^2
Where N and P are the factors
(N/P)^2 = 5/45
N/P = sqrt root (1/9)
N/P = 1/3
Cross multiply
P = 3N
The scale factor James used to go from Rectangle N to Rectangle P is therefore equal to 3 or 3:1
Answer: Your answer is B!
Good luck!
