Answer:

Distance=9.43 units

Step-by-step explanation:

When you have two coordinates and you need to find the distance between them, you can use the distance formula.

D=sqrt(7-2)^2+(3-(-5))^2

D=sqrt(5^2+8^2)

D=sqrt(25+64)

D=sqrt89

D=9.43, rounded to the nearest hundredth.

Therefore, your distance would be 9.43 units.

I hope this helped! Have a good rest of your day~

Could someone please help me answer this math question

Greeley [361]

Explanation

5 students got 6 mark each, 4 students got 7 marks each, 7 students got 8 marks each, 10 students got 9 marks each and 4 students got 10 marks each.

(a) Range is the difference of highest mark and lowest mark. Here, the highest mark is 10 and lowest mark is 6.

So, the range of mark $= 10-6 = 4$

(b) Total number of students in the group $= 5+4+7+10+4= 30$

(c) Mean is the simple average. So, for finding the Mean, we will divide the total marks obtained by all students by the total number of students.

Total marks obtained by all students

$= (6*5)+(7*4)+(8*7)+(9*10)+(10*4)\\ \\ = 30+28+56+90+40 = 244$

So, the Mean mark of the group $=\frac{244}{30}=8.13333....$
