Answer:
1/5 - 60 or b
Step-by-step explanation:
Answer:
x = 15°
Step-by-step explanation:
<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>
=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>
=> <em>So the angle (not 75 and x) is 90 degrees.</em>
<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>
<em>So,</em>
=> x = 180-90-75
=> x = 15°
5/4=15/12
1/3=4\12
15+4=19
=19/12= 1 and 7/12
Answer:
(a) 0.12 (b) 0.32 (c) 0.56
Step-by-step explanation:
The sample outcomes are Funded or Unfunded. Total sample space is given by:
2²= 4
Fund = F
Unfunded = U
P (F) ist panel = 0.2
P (U) ist panel = 0.8
P (F) 2nd panel = 0.6
P (U) 2nd panel = 0.4
TOTAL SAMPLE SPACE
Ist Panel Second Panel
F F
F U
U F
U U
(a) Probability of both panel approval = P (FF)
= 0.2 x 0.6
= 0.12
(b) Probability of approval disapproved by both panels = P (UU)
= 0.8 x 0.4
= 0.32
(c) Probability of a worthy disapproval by one panel = P(FU) + P(UF)
= (0.2 x 0.4) +(0.8 x 0.6)
= 0.08 + 0.48
= 0.56
