The average speed is 97346 feet per hour approximately
<em><u>Solution:</u></em>
Given that blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12 hours 22 minutes
To find: average rate of speed in feet per hour
<u><em>The speed is given by formula:</em></u>
From given information,
We know that,
Therefore,
Substituting the values in above formula,
Thus average speed is 18.4366 miles per hour
<em><u>Let us convert to feet per hour</u></em>
We know that,
1 mile = 5280 feet
Therefore,
18.4366 miles = 18.4366 x 5280 feet = 97345.248 feet
Thus average speed is 97346 feet per hour approximately
Answer:
wow nice question but sorry can't answer
Step-by-step explanation:
Cross multiply and solve for x.
X represents the smaller of the two groups.
4/11 = x/33 .
For the first question, we need two angles sitting on the line. We do not know if segments EG and AB are perpendicular, so cannot assume, even though they look like it.
A. DGB and EGA do not even have one leg common, so cannot be supplementary. so no.
B. DGB and CGB together add up to angle DGC which we know is a straight line. so yes.
C. CGB and AGD are vertical angles, and nothing tells us any of them is a right angle, so no.
D. EGA and EGC make an angle between segments CD and AB. so no.
E. EGD and CGB could be supplementary if we know CGB=EGC. But since we don't, so no.
For the second question, yes, you're right, take the second option in both, i.e. rotate 90 degrees (i.e. counterclockwise) about A, followed by a reflection about y, then translate downwards 20 units will give exactly GHIJ.
The fourth, rotate about B 90 degrees, then reflect about y-axis and translate down 25 is close, but need another translation (2,-1) to fit in the right place.
Answer:
estimated sample mean X is 14.7 minutes
sample standard deviation is ≈ 0.59 minutes.
Step-by-step explanation:
Let X be the mean delivery time for a random sample of 40 orders at this restaurant, then
X can be estimated as 14.7 minutes (mean delivery time for all food orders at a fast-food restaurant during the lunch hour)
Let s be the standard deviation of delivery time for a random sample of 40 orders at this restaurant, then
≈ 0.59 where
- 3.7 is the standard deviation of the delivery times for all food orders at a fast-food restaurant during the lunch hour
- 40 is the sample size
