Answer: b) x = 6 and total line is 52
c) x = 5.5 and total line is 20
Step-by-step explanation:
b) (x+20) = (5x-4)
4x = 24
x = 6
Line (x+20) = 26
Line (5x-4) = 26
Total line = 52
c) (4x-12) = (-2x+21)
6x = 33
x = 5.5
Line (4x+12) = 10.0
Line (-2x+21) = 10.0
Total line = 20
Answer:
There is no enough evidence to claim that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.
Step-by-step explanation:
The question is incomplete: the table is attached as picture.
The researcher was attempting to show statistically that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.
As result from the test we have a t-statistic with a value t=-1.37631.
We don't know the significance level, but we know that the critical value that separates the acceptance region from the rejection region is tc=-1.70113.
To be the difference between means statistically lower than 0, the t-statistic should be lower than the critical value.
This is not the case, so the null hypothesis failed to be rejected.
There is no enough evidence to claim that the female MBA graduates have a significantly lower mean starting salary than the male MBA graduates.
Answer:
-6:No
-2:No
7:No
8:No
The only number to make this equation true is 1
Step-by-step explanation:
I will substitute each value in place of the variable. Hopefully you understand PEMDAS
3(-6)+5=8
-18+5=8
-13=8
-13 does not equal 8 so false.
3(-2)+5=8
-6+5=8
-1=8
-1 doe not equal 8 so false
3(7)+5=8
21+5=8
26=8
26 does not equal 8 so false
3(8)+5=8
24+5=8
29=8
29 does not equal 8 so false
Let's see what would make this true:
3x+5=8
3x=3
×=1
