x is 6.
3 / 5 = 6 / 10
Where 10 / 5 = 2 then 2 * 3 = 6.
6 / 10 simplified by dividing both numerator and denominator by 2 will result to 3 / 5.
Answer:
No, he would not be able to reach the town in 4 hours with two 10 minutes stops and same speed
Completed question;
Max travels to see his brother's family by car. He drives 216 miles in 4 hours. What is his rate in miles per hour? Suppose he makes two stops of 10 minutes each during his journey. Will he be able to reach the town in 4 hours if he keeps the speed the same?
Step-by-step explanation:
Average speed = total distance travelled/time taken
Given;
Total distance travelled= 216 miles
Total time taken = 4 hours
Average speed v = 216/4 = 54 miles per hour
v = 54 mph
Suppose he makes two stops of 10 minutes each during his journey.
Total time on stops = 2 × 10 = 20 minutes = 0.33 hours
Total time spent on motion = 4 - 0.33 hours = 3.67 hours
Total distance covered in 4 hours with two stops;
d = 3.67 × 54 mph = 198.18 miles
Since d < 216 miles
No, he would not be able to reach the town in 4 hours with two 10 minutes stops and same speed
Answer:
Step-by-step explanation:
Let x = $ invested in 8% account
y= $ invested in 10.5% account
x + y= 12000
0.08x + 0.105y = 1145
$4600 invested in the 8% account
and $7400 invested in the 10.5%
account
Answer:
D) Standard deviation is 5.41
Step-by-step explanation:
We are given
count N = 9
Sum ∑xi = 113
Mean = ∑xi /N = 12.55
Standard deviation = 
where i = 1 to 9
upon substituting the values we get
Standard deviation = 
= 5.41
So if we have 52 cards it would be easy to check the odds with a formula, here is the procedure:
<span>P(Ace) is 4/52 = 1/13
P(Spade) is 13/52 = 1/4
P(Ace and Space) = 1/52
therefore P(Ace or Spade) = 1/13 +1/4 - 1/52 = 4/13 =</span><span>0.30769230769230769230769230769231. that is the probability</span>
