Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b
Answer:
h = √72 in.
Step-by-step explanation:
Height of the cone using pythagorean theorem, a² + b² = c², where:
a = h
b = ½(6) = 3 in.
c = 9 in.
Plug in the values
h² + 3² = 9²
h² + 9 = 81
h² + 9 - 9 = 81 - 9
h² = 72
h = √72

C. Find the equation that is parallel to y = 12x-2 and crosses the point (6,2)
Answer:
The equation of line a is y=(1/2)x−1, and it passes through point (6,2).
line b is: y = -2x + c and we use point (-6,2) to find b.
2 = -2(-6) + c
14 = c
The equation for line b is: y = -2x + 14
The y-intercept (which is the point where x=0) is the point (0,14.) So, y=14

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15
Answer:
9 = x (assuming 15 is the hypotenuse)
Step-by-step explanation:
15^2 = 12^2 + x^2
225 = 144 + x^2
subtract 144 from both sides
81 = x^2
square root both sides
9 = x

$45.00 iPod shuffle 1GB
10% or markdown plus sales tax 10%
What will the sale price be if you purchase this item?
Answer:
$44.55
Step-by-step explanation:
10% of 45 is 4.5
45 * 0.1 = 4.5
So subtract 4.5 from 45
45 - 4.5 = 40.5
Now get 10% of 40.5
40.5 * 0.1 = 4.05
Add 4.05 to 40.5
4.05 + 40.5 = 44.55

From a random sample of 185 children from school G, 108 indicated they wanted to study science in college. From a different random sample of 165 children from school H, 92 indicated they wanted to study science in college. Assuming all conditions for inference are met, which of the following is closest to the standard error for a confidence interval for the difference in population proportions between the two schools of children who want to study science in college?A. 1.96 underroot(200/350)(1 − 200/350)/350.B. Underroot(108/185)(1 − 108/185)185 − (92/165)(1−92/165)/165.C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.D 1.96 underroot(108/185)(1 − 108/185)185 + (92/165)(1 − 92/165)165.E. Underroot(200/300)(1 - 200/300)/350.
Answer:
C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.
Step-by-step explanation:
Sample size, n1 = 185
x1, = 108
P1 = x1 / n1 = 108 / 185 =
Sample size, n2 = 165
x2, = 92
P2 = x2 / n2 = 92/165
Standard Error = sqrt[(p1(1-p1))/n1 + (p2(1-p2))/n2]
sqrt[(108/185(1 - 108/185)) /185 + (92/165(1 - 92/165)) / 165]
