Answer:
3,4.5,6
Step-by-step explanation
0+ what gives 1.5=1.5 keep adding that and you'll get 3-4.5-6
X values is domain and y value is range
Answer:
Option (a) narrower and would involve a larger risk of being incorrect.
Step-by-step explanation:
We have to compare a 95% confidence interval to a 99% confidence interval.
- For a 95% confidence interval and 99% confidence interval, confidence level is lower for 95% confidence interval.
- With a lower confidence level, there would be less margin of error.
- Thus, 95% confidence interval is narrower as compared to the 99% confidence interval.
- Since, a 95% interval is narrower there are less values included in the interval that could give right estimate for the parameter.
Thus, we can write,
Compared to a 95% confidence interval, a 99% confidence interval will be Option (a) narrower and would involve a larger risk of being incorrect.
Answer:
yes the ladder is safe
Step-by-step explanation:
if im not mistaken you usual want the ladder to be taller than the roof and feet close to the wall
Answer:
For no. 1:
One of the equations say that y=-7x
So plug in -7x to the other equation as y so you equation would be
-7x= -6x-7
And then, just solve for the variable:
*add -6x to both sides*:
-x= -7
*multiply both by negative one to get a positive variable*
FOR NUMBER 1, THE ANSWER IS:
x=7
Y=-7
For no. 2:
-y=x and your other equation is 3x+5y=20
Plug in x as -y:
-3y+5y=20
*simplify*
2y=20
*divide by 2 on each side to get 1 variable alone*
Y=10
FOR NUMBER 2, THE ANSWER IS:
x=-y
Y=10
