Answer:
f(-1) = 11
Step-by-step explanation:
f(x) = 2x^2 - 6x + 3
Let x = -1
f(-1) = 2(-1)^2 -6(-1) +3
=2*1 +6 +3
=2+6+3
= 11
Answer:
area = 117
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = 
h (b₁ + b₂ )
here h = 6, b₁ = 14 and b₂ = 25
A = × 6 × (14 + 25) = 3 × 39 = 117
D because the parallel sides are both considered bases
Answer:
5
Step-by-step explanation:
Given that each zodiac sign occupies 1/12 of a year.
Then the minimum number of persons for Y[all different signs] < 0.5,
The probability of at least two having the same sign is 1 minus the probability of all having different signs.
This can be represented as A [at least 2 person share the same sign] = 1 - Y[all different signs] must be > 0.5
Therefore we have 1 - 12/12 *11/12 * 10/12 *9/12 *8/12 = 0.38
This implies that the lowest number will be found to be 5
Hence, the correct answer is 5.
