Answer: The equation is true
Step-by-step explanation:
Since x=3 and y= 5
Substitute the values for x and y
y=2x-1
5=2(3)-1
5=6-1
5=5
⇒The equation is true
Answer: Undefined
Step-by-step explanation:
slope is undefined
no y intercept
This line is vertical
Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b
so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3
Answer:
Inches are not an appropriate unit of length for the distance from your home to school because it is a short unit of measurement and using feet or meters would be a better solution since feet and meters are both a longer unit of measurement and feet and meters would be a more accurate answer than inches.
Step-by-step explanation:
Answer:
No, this result is not surprising. It is a little bit more than one standard deviation above 20%
Step-by-step explanation:
Proportion of each color in the population (p) = 0.20
Sample size (n) = 20 Skittles
The standard deviation of a sampling distribution is determined by:
The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
