Answer:
x = 8
Step-by-step explanation:
Her mistake was subtracting 2 on both sides. Instead she should've added 2 on both sides.Getting a result of 2x=16. Then you divide 2 on both sides to get x = 8.
Biker's rate is:
v = 5/0.5
v = 10 ft per sec
t = 1 min = 60 sec
d = the distance the biker travels in 1 minute
v = d/t
d = v*t
d = 10*60
d = 600 ft
The biker travels 600 feet in 1 minute
Answer: ) Events A and B are such that: P(A) = 0.4; P(B) = 0.5; P(A n B) = 0.3; and P(A u B) = 0.6. i) What is the value of P(A u B')? (Where B' is the compliment of B.) 0.
Step-by-step explanation: I just did a little extra credit :D
When you divide a fraction by a fraction, you're really just multiplying by a reciprocal. A reciprocal is the fraction flipped around.
So, 1/8 <span>÷ 1/4 is the same thing as 1/8 x 4/1
Now, you just multiply. 1 times 4 is 4. 8 times 1 is 8.
1/8 x 4/1=4/8
4/8 simplified is 1/2
So that is how 1/8</span><span>÷1/4=1/2</span>
It would be: 0.83 = 83/100
In short, your answer would be 83/100
Hope this helps!
