Answer:
D
Step-by-step explanation:
7.6/3.8 = 2
The dilation is by scale factor 2.
8/2 = 4
11/2=5.5
Calculate the volume.
Cross section × height
4 × 3.8 × 1/2 × 5.5 = 41.8
The volume of the smaller prism is 41.8 ft³.
Answer:
Rose plants has the greatest number of plants that can be put in one row that is 27
Step-by-step explanation:
If you wanted to plant 45 sunflowers and 81 rose plants in your garden you have to see which one has more and you get rose plants.all you have to do is subtract 1 from 81 and then put it with sunflowers.
1) The domain of the graph is the set of x-values for which the function is defined, that is - x ≥ 0 => x ≤ 0 => all real numbers less than or equal to zero.
2) The range of the grpah is the set 0 images (or y-values) feasible. As you see on the graph that is y ≤ 0 => all real numbers less than or equal to zero.
3) Conclusion: the only statement that meet those facts is the third one: the range and the domain of the graph are the same.
Answer: the third option: the range and the domain of the graph are the same.
Answer:
Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
Step-by-step explanation:
1)Formulate the hypothesis that first variance is equal or greater than the second variance
H0: σ₁²≥σ₂² against the claim that the first instructor's variance is smaller
Ha: σ₁²< σ₂²
2) Test Statistic F= s₂²/s₁²
F= 84.8/ 58.9= 1.4397
3)Degrees of Freedom = n1-1= 10-1= 9 and n2 = 10-1= 9
4)Critical value at 10 % significance level= F(9,9)= 2.4403
5)Since the calculated value of F = 1.4397 is less than the critical value of
F (9,9)= 2.4403 we conclude that the first instructor's variance is smaller and reject H0.
