Answer:
f(-2) =8
Step-by-step explanation:
f(x) = 3x^2+x-2
Let x = -2
f(-2) = 3 * (-2)^2 + (-2) -2
= 3(4) -2 -2
=12 -2-2
=10 -2
=8
Answer:
x=1
Step-by-step explanation:
First you would do the parentheses.
So, 4 x X= 4x
4x2=8
4x+8=2x+10
subtract 2x on both sides
2x+8=10
subtract 8 from both sides
2x=2
x=1
Answer:25 percent
Step-by-step explanation:
Answer:
<h2><em>11.6%</em></h2>
Step-by-step explanation:
The probability of getting a 6 is 1/6.
The probability of not getting a 6 is 5/6
We roll a die 4 times and want 2 sixes, and 2 not sixes.
i.e.exact 2 6's
We want a combination of 2 sixes from 4 rolls, so we can use the binomial formula to solve this
(4C2)(1/6)²(5/6)² = 6(1/36)(25/36) = (1/6)(25/36) = 25/216 = 0.1157
Nearest tenth of percent is 0.1157×100=11.6%
Ans :11.6%
