Suppose :
2^x = t ..**&**.. 3^y = u
_____________________________
t + u = 9 × 3 3t + 3u = 27
=====》
2t - 3u = 8 2t - 3u = 8
+ __________
5t = 35
5 × t = 5 × 7
t = 7
&
u = 2
________________________________
Thus :
2^x = 7 ===》 x = Log _ 2 { 7 }
3^y = 2 ===》 y = Log _ 3 { 2 }
Answer: Two-tailed test.
Population mean is the parameter which is tested.
Step-by-step explanation:
Given : 

We know that , the alternative hypothesis (
) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.
Here, the alternative hypothesis (
) is two-tailed, so the hypothesis test is a two-tailed test.
Also, the parameter present in the hypothesis is
which is a symbol to represent the population mean.
Thus , Population mean is the parameter which is tested.
Answer:
inches
Step-by-step explanation:
13*6*2.5
Answer:
10cm (I think)
Step-by-step explanation:
2/3 = .66666666 x 6 = 4
4 +6 = 10
Y = -4x + 7
This is the equation of the line. The slope is -4. The Y- intercept is 7
