Cycled 480 meters but a<span>fter cycling 0.25 of the distance Wendy stopped and waited for Rick to catch up
0.25 (480) = 120 meters
</span><span>Wendy cycled at a speed of 80 meters per minute = 120 /80 = 1.5 minutes
</span><span>Rick's speed was 20 meters per minute slower than Wendy's = 120 / 60 = 2 minutes
so </span>2 minutes - 1.5 minutes = 0.5 minutes
answer
<span>Wendy waited 0.5 minutes for Rick </span>
Hello you would expect to recieve around 500 dividend each year
Answer:
x=8
Step-by-step explanation:
The side G-F is the same side as side Q-R so 2 times 8 is 16
and 16 - 4 is 12
so x=8
Answer:
E) 166
Step-by-step explanation:
Standard deviation is 10
Margin error for the problem is 2
Probability 99%, that means thet the siginficance level α is 1 – p
α = 1 – 0.99 = 0.01
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.01/2) = Z(0.005)
Using a z table Z = 2.576
Now, replacing in the equation and find n
2 = 2.576 * 10/ √n
2 = 25.76 /√n
√n = 25.76 /2
√n = 12.88
n = 12.88^2
n = 165.89 ≈166
