Answer:
Value of f (Parapedicular) = 7√6
Step-by-step explanation:
Given:
Given triangle is a right angle triangle
Value of base = 7√2
Angle made by base and hypotenuse = 60°
Find:
Value of f (Parapedicular)
Computation:
Using trigonometry application
Tanθ = Parapedicular / Base
Tan60 = Parapedicular / 7√2
√3 = Parapedicular / 7√2
Value of f (Parapedicular) = 7√2 x √3
Value of f (Parapedicular) = 7√6
You can divide 1/2 by 1/4
that'll leave you with 1/8, which is smaller than 1/4
Answer:
Step-by-step explanation:
Statement Reason
1.∠4 is an exterior angle of ΔABC Given
2.∠3 and∠4 form a linear pair Linear pair theorem
3.∠3 is supplementary to ∠4 Property of supplementary angle
4.m∠3+m∠4=180° Definition of supplementary angle
5.m∠1+m∠2+m∠3=180° Triangle sum theorem
6.m∠1+m∠2+m∠3=m∠3+m∠4 From step 4 and 5
7.m∠1+m∠2=m∠4 Subtraction rule
Answer: 2.77
The expected value is positive, so you expect to gain on average $2.77 per draw.
================================================
Explanation:
Define two events
W = winning = getting a card 4 or less
L = losing = getting 5 or higher
P(W) = probability of winning
P(W) = 12/52 since there are 12 cards that are four or less out of 52
P(W) = 3/13 for any suit of 13, there are 3 cards that are four or less
P(L) = 1-P(W)
P(L) = 1-3/13
P(L) = 13/13 - 3/13
P(L) = 10/13
V(W) = net value of winning
V(W) = 162
V(L) = net value of losing
V(L) = -45
------------------
E(X) = expected value
E(X) = P(W)*V(W) + P(L)*V(L)
E(X) = (3/13)*162 + (10/13)*(-45)
E(X) = 36/13
E(X) = 2.76923076923077
E(X) = 2.77 rounding to two decimal places (to the nearest cent)
This game is in favor to the player since we got a positive expected value. A fair game would occur if the expected value was 0.
This is the concept of volumes of solid figures, given that the height of the right rectangular prism and the oblique triangular prism are 12 cm and both prisms have the same volume, we can conclude that:
Horizontal cross-sections of the prisms at the same height have the same area.
