To answer this you will use the formula V = pi x radius ^2 x height. The substitution for this would be 3.14 x 4^2 x 8. The approximate answer is 401.92 cubic units. 3.14 is an approximation of pi.
Note: It does not say that x is the height, but this is the only piece of information missing without an obvious label, so I am using it as the height.
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Percentage of students in the class of 2013 has done an internship during their time as an undergraduate student = 38% = p₀
Number of architecture majors = 100
We need to check that whether students at her university had an internship rate that was higher than the national average.
Proportion for her university = 43% = p₁
Here, n = 100
Since n > 30.
so, we can use z-test.
Z-test is generally use to identify whether two means are different when the standard deviation is given.
Hence, it is safe to use the z-test for p.
Therefore, option 'a' is correct.
Answer:
<h3>CHOICE A.</h3>
Step-by-step explanation:
<em><u>There are 2 p’s and 3 q’s. So it is choice a.</u></em>
Answer:
Identical shapes
Step-by-step explanation:
My own words?
Two or more shapes that are the same.
49x^2 + 64y^2 = 3136 . . . (1)
y - 6 = (1/4)x^2 . . . (2)
From (2), x^2 = 4(y - 6) = 4y - 24 . . . (3)
Putting (3) into (1) gives
49(4y - 24) + 64y^2 = 3136
196y - 1176 + 64y^2 = 3136
64y^2 + 196y - 4312 = 0
y = 6.819
x = sqrt(4(6.819) - 24)
x = 1.81
The possible point of collision is (1.81, 6.819)
