Answer:
3x² + x -
Step-by-step explanation:
1/2bh
1/2(x-9+x+8)(3x+3)
1/2(2x-1)(3x+3)
1/2(6x²+6x-3x-3)
3x² + x -
Answer:
Approximately 23%
Step-by-step explanation:
we know that
The high school graduating class of 2010 was 260 people
5 years later the high school graduating class was 320 people
In this problem
260 people represent the 100%
so
using proportion
Find out what percentage represent the difference (320-260)=60 people
Let
x -----> the percentage
Answer:
a) 0.004
The probability of getting exactly 8 heads

Step-by-step explanation:
<u><em>Explanation:</em></u>-
The probability of getting a Head, p =
The probability of getting a Tail, q =
A coin is flipped 8 times
n = 8
Let 'X' be the random variable in a binomial distribution
The probability of getting exactly 8 heads
<u><em>Final answer:-</em></u>
The probability of getting exactly 8 heads
P(X=8) =0.0039≅ 0.004
Answer:
Step-by-step explanation:
Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.
tan(x) = 7/24
sin(x)/cos(x) = 7/24
sin(x) = 7/√(7²+24²) = 7/√625 = 7/25
