Answer:
c. -1.5 < -0.5
Step-by-step explanation:
a. -1.5 > 0.5 . . . . false
b. -0.5 > 0 . . . . . false
c. -1.5 < -0.5 . . . TRUE
d. 1/2 > 0.5 . . . . false (these are the same number) 1/2 = 0.5
_____
In order on the number line from left to right, you will see ...
(left end) ... -1.5 ... -0.5 ... 0 ... 0.5 ... (right end)
__
The inequality relation appropriate to these is ...
(number on the left) < (number on the right)
Of course, this can be swapped around so you have ...
(number on the right) > (number on the left)
Answer:
Step-by-step explanation:
In the two independent samples application, it involves the test of hypothesis that is the difference in population means, μ1 - μ2. The null hypothesis is always that there is no difference between groups with respect to means.
Null hypothesis: ∪₁ = ∪₂. where ∪₁ represent the mean of sample 1 and ∪₂ represent the mean of sample 2.
A researcher can hypothesize that the first mean is larger than the second (H1: μ1 > μ2 ), that the first mean is smaller than the second (H1: μ1 < μ2 ), or that the means are different (H1: μ1 ≠ μ2 ). These ae the alternative hypothesis.
Thus for the z test:
if n₁ > 30 and n₂ > 30
z = X₁ - X₂ / {Sp[√(1/n₁ + 1/n₂)]}
where Sp is √{ [(n₁-1)s₁² + (n₂-1)s₂²] / (n₁+n₂-2)}
What you're doing is just dividing 13/8 to find the decimal (1.625) and then divide that number by 100. 162.5%
your answer is 162.5%
Answer:
3. 112.2 yd
4. 30m
Step-by-step explanation:
Number 3:
- L × W (length × width) = A
- 18.7 × 6 = 112.2 yd
Number 4:
- B × H (base × height) = A
- 6 × 5 = 30 m
I hope this helps!
