Answer:
y= -3x-16
Step-by-step explanation:
slope intercept form is written as y=mx+b. m is the slope, and b is the y-intercept. -3=m
we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15. subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).
Answer:
At first we will divide 233 with 5
233/5= 46.6
So,
there will be 46.6 chairlifts occupied
After that we will subtract 233 from 46
233-46=186/5=37
So,
there will be 37 skiers on the last chair lift
Step-by-step explanation:
Answer:
the answer is negative two / x= -2
it goes up 0.8 every time
Answer:
Step-by-step explanation:
The hypothesis being tested is:
H0: ρ = 0
Ha: ρ ≠ 0
Pearson's r is -0.140.
The critical r-value is 0.404.
Since 0.140 < 0.404, we cannot reject the null hypothesis.
Therefore, we cannot conclude that notebook computer use and grades are related.
Pearson's r is -0.140. It means that there is a weak negative relationship between notebook computer use and grades.
The coefficient of determination is 0.020. 2% of the variation in the model is explained.
The relationship is not significant.
