Answer:
$3.50
Step-by-step explanation:
Given:
$10 for a 6, $7 for a 5, $4 for a 4, and no payoff otherwise
P(6) = 1/6 ; p(5) = 1/6 ; p(4) = 1/6 ; p(1,2or3) = 3/6 = 1/2
P(x) ____ 1/6 _____ 1/6 _____1/6 _____1/2
x______ 10 _______ 7 _____ 4 _______ 0
Expectwd value ; E(x)
Σx*p(x) = (1/6 * 10) + (1/6 * 7) + (1/6 * 4) + (1/2 * 0)
E(x) = 3.50
slope = 13
the slope of the tangent is f'( 4)
given f(x) = x² + 5x , then f'(x) = 2x + 5
and f'(4) = ( 2 × 4 ) + 5 = 13
Answer:
its scalene triangle since for iscocles two legnths are equal.
Step-by-step explanation:
answer from GAUTHMATH
Understand wuttttttttttttttttttttttttttttt
For values to have congruent sin and cos value, it means that sin x=cos y
thus from the given values, the values that sin x is congruent to cos y will be found as follows;
70
sin 70=0.9397
getting the cosine for y values we get:
cos 160=-0.9397
cos 70=0.3420
cos 120=-0.5
cos 20=0.9397
from the above we see that the cosine value congruent to sin 70 is cos 20
