Answer: D
Step-by-step explanation:
The answer is B
X = 3 and 1/2= Y
3 + 2(1/2) = 4
3 + 1 = 4
Half of 2 = 1, making B the answer
Using the formulas
:
A=2AB+(a+b+c)h
AB=√(s(s﹣a)(s﹣b)(s﹣c)
)
s = (a+b+c) / 2
Solving for A:
A=ah+bh+ch+1
/2 √(﹣a∧4+2(ab)∧2+2(ac)∧2﹣b∧4+2(bc)∧2﹣c∧4)
=2·1.7+3·1.7+2·1.7+1
/2· √(﹣2∧4+2·(2·3)∧2+2·(2·2)∧2﹣3∧4+2·(3·2)∧2﹣24)
≈15.86863
Answer:
The expectation the instructor to send each day
E(X) = 3.65
Step-by-step explanation:
Given data x : 0 1 2 3 4 5
P(X=x) : 0.05 0.05 0.1 0.1 0.4 0.3
The given data satisfy the two conditions
I) Given all probabilities are p₁(x) ≥0
ii) sum of all probabilities is equal to one
0.05 + 0.05 + 0.1 + 0.1 + 0.4 +0.3 =1
Therefore given data is discrete probability distribution
<u>Expectation</u> :-
suppose a random variable X assumes the values
with respective probabilities
, then the Expectation or Expected value of X , denoted by E(X) = ∑pi xi

on simplification, we get
E(X) = 3.65

Answer:
98°
Step-by-step explanation:
Inscribed angle FGH is half the measure of the intercepted arc FH. The measure of arc FH is identical to the measure of central angle FIH. So, angle FIH has twice the measure of inscribed angle FGH:
∠I = 2×∠G = 2×49°
∠I = 98°
