You have to work to buy a calculator is 30multiplying by 7.50=225
Answer:
∫₋₃¹ π y⁴ dy
Step-by-step explanation:
If we slice the solid shape, we get circular cross sections or disks. The thickness of each disk is dy. The radius of each disk is x. So the volume of each disk is:
dV = π r² h
dV = π x² dy
Since x = y²:
dV = π y⁴ dy
The total volume is the sum of all the disks from y=-3 to y=1.
V = ∫ dV
V = ∫₋₃¹ π y⁴ dy
Answer:
Step-by-step explanation:
a) From the information given, we can state the hypothesis as follows:
For null hypothesis,
p = 0.9
Or
p ≤ 0.9
For alternative hypothesis,
p > 0.9
Because of the greater than inequality symbol in the alternative hypothesis, it means that it is a right tailed test.
b) Since z = 2.31, we would determine the p value by looking at the probability corresponding to the area above the z score from the normal distribution table. Thus
P value = 1 - 0.9896 = 0.0104
Using a significance level of alpha equals 0.10, since alpha, 0.10 is > p value, 0.0104, then we would reject the null hypothesis.
Answer:
You get $5727.27
Step-by-step explanation:
At the start, you have 2000
After you are attacked, stampeded and have trouble finding water, you have lost 10% of your cattle
2000 * 10% is 200
2000 - 200 is 1800
Multiply 1800 cattle by $35 per cow
1800 * $35 = $63000
10 cowboys + 1 (you) is 11 people
Divide $63000 by 11
63000 / 11 = $5727.27
You get $5727.27
The domain is the entire list of x values, while range would be the same for y. In a graph, we're always going to have a coordinate pair for every point, so more x's than y's or more y's than x's doesn't make sense, there can't be a sole x or y value. Hope this helps!
