Can someone answer the question ??
Temka [501]
Answer:
Faris' arrival time = 3:30 pm + 3 h 54 mnt = 7:24 pm
Step-by-step explanation:
Driving distance between Manchester to London = 195 miles
Coach left Manchester = 3.30 pm
Average speed of coach = 50 mph
Total time taken by the coach to reach the Manchester to London = 195÷50 = 3.9 h
0.9 h = 0.9×60 mnt = 54 mnt
Now,
3.9 h = 3 h 54 mnt
Hence Faris' arrival time in London = 3.30 pm + 3 h 54 mnt = 7.24 pm

I’m confused on this one
White raven [17]

All of the angles add up to 360 degrees.

180(4-2) = 360


9x+1+5x-12+8x+61

Add up all the like terms

22x+50= 360

x=14.1


We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.

Angle C: 9(14.1) + 1 = 127.9

Angle D: 5(14.1) - 12 = 58.5

Angle A: 8(14.1) + 61 = 173.8


All of these angles add up to 360


This means that angle D is 0 degrees since all of the other angles already add up to 360.


<u>Answer</u>

0 degrees

A set of data has a normal distribution with a mean of 5.1 and standard deviation of 0.9. Find the percent of data between 6.0 a
jolli1 [7]

The percent data between 6.0 and 6.9 would be 13.59%. Here’s the complete solution for this specific problem.

<span>z = (X - Mean)/SD </span><span>
<span>z1 = (6 - 5.1)/09 = + 1 </span>
<span>z2 = (6.9 - 5.1)/09 = + 2 </span>
<span>Required Percent = P(6 < X < 6.9)*100 </span>
<span>= P(1 < z < 2)*100 </span>
<span>= [P(z < 2) - P(z < 1)]*100 </span>
<span>= [0.9772 - 0.8413]*100 </span>
<span>= 0.1359*100 </span>
<span>= 13.59%

I am hoping that this has answered your query.</span></span>
