Answer:
Option 3 is right
Start at the origin. Move 3 and one-half units down because the x-coordinate is Negative 3 and one-half. Negative 3 and one-half is between -3 and -4. Move 2 units right because the y-coordinate is -2.
Hope this helps:)
Answer:
y = 2x-3
Step-by-step explanation:
We can use those 2 points given to solve for the slope (m) and for the y-intercept (b) in the equation y = mx+b
<u>Slope:</u>
(3,3) and (4,5)
m =
m =
m = 2
<u>Y-intercept:</u>
y = 2x+b
3 = 2(3) +b
3 = 6+b
b = -3
equation: y = 2x-3
Answer:
x=9
Step-by-step explanation:
Since ABCD is a square, we know that AC bisects ∠BCD(=90), and therefore ∠ACB=45.
8x-27=45
8x=72
x=9
Answer:
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
Step-by-step explanation:
A confidence interval has the following format.
In which is the mean of the sample and M is the margin of error.
In this problem, we have that:
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
False, because you can do 2 x 0.5 and you would get 1. And 1 is less than 2
