Answer:
See below.
Step-by-step explanation:
Multiplying terms with exponents make the exponents add together.
13.) x² · x⁵ = x⁷
14.) b⁵ · b³ = b⁸
15.) y⁴ · y⁷ = y¹¹
16.) m⁴ · m¹ = m⁵
Answer:
a. difference of means
Step-by-step explanation:
Given that :
Mean , x = 9.4
Standard deviation, 
= 2.5
Number, 
= 12
Mean, y = 6.5
standard deviation, 
= 2.4
Number, 
= 12
The null hypothesis is : 
The alternate hypothesis is : 
Level of significance, 
= 0.1
From the 
= 1.363
Since out test is right tailed.
Reject 
, if 
We use the test statics,
The value of 
with minimum 
that is 11 df is 1.363
We go and = 1.363
Decision making:
Since the value of 
and we reject the
The p-value : right tail 
= 0.00724
Therefore the value of 
, and so we reject the
Thus we are testing 'the difference of means" in this problem.
Kind of true and kind of false : Sometimes they are, but there is nothing that force two acture triangles to be similar, even if they have the same measurement of the acute angle.
For that you would need to have 3 angles the same.
For example, if the angles were 40-60-80, you have an acute triangle. But if you had a 45-55-80 triangle, that is also acute, but not similar even though it shares an angle of 80 degrees.
Answer:
It would be 40 Orange Juice cup
Step-by-step explanation:
Cause 12 times 5 would equal 60
So if you times 5 and 8 it would be 40
