Y=1x+1 should be the answer ^
So just plug in the numbers (x,y) into the equations.
A) (7.5, -5)
2(7.5) -5 = 10
15 - 5 = 10 yup, this works.
Let's see if it works for other equation.
-2(7.5) + 2(-5) = 5
-15 - 10 = 5 nope, this does not work.
B) (-2.5, -5)
2(-2.5) - 5 = 10
-5 - 5 = 10 nope, doesn't work
Since it doesn't work we don't need to try for other equation.
C) (2.5, 5)
2(2.5) + 5 = 10
5 + 5 = 10 yup, this works.
Now the other equation.
-2(2.5) + 2(5) = 5
-5 + 10 = 5 and this works.
So the solution to this set is answer choice C
Answer:
the graph that best corresponds to the function in the given interval is the down left graph.
Step-by-step explanation:
Given : f(x)= [x]-3 and graph .
To find : Which graph represents the function on the interval [-3 , 3] ?
Solution : Let's evaluate the extremes of the interval in given function f(x).
X= -3, f( -3 )= [ -3 ] - 3 .
f( -3 ) = -6 .
X= 3, f( 3 )= [ 3 ] - 3 .
f( 3 ) = 0.
Therefore, the graph that best corresponds to the function in the given interval is the down left graph.
Answer: The level of significance, , is the probability of committing a Type I error, rejecting the null hypothesis when it is, in fact, true.
Step-by-step explanation:
The significance level, which is commonly designated as alpha (α) is defined the probability of rejecting the null hypothesis when it is in fact, true.
To determine statistical significance, a researcher is expected to calculate a p-value. The researcher can reject the null hypothesis if the p -value is less than α as established by the researcher.
