Answer:
Two tailed test
+/-1.96
Step-by-step explanation:
Following this claim, the president would have to perform a two tailed test. Since he wants to know if the Act scores of students in her school are significantly different from what is reported by the ACT corporation.
At a confidence level that is 95%, the level of significance is = 0.05. then the z critical value to be used would be +/- 1.96
Answer:
B
Step-by-step explanation:
slope formula
we have the two points
(2,4) (3,7)
which means the slope for line m is 3x
our equation so far looks like this
y=3x+b
plug in a set of numbers to solve for b
let's use (2,4)
4=3(2)+b
4=6+b
b= -2
which means our equation is
y= 3x-2
which is equal to
2= 3x-y
the only answer is then B
Step-by-step explanation:
if the two integers are x and y
x+y=11
xy= 24
x+24/x=11
x2-11x+24=0
(x-8)(x-3)=0
x =8 or x=3
if x=8,y=3
if x=3,y=8
so the two integers are 3 and 8
