Answer:
The third one
Step-by-step explanation:
If you look at the graph you see that the relationship between the points is linear positive correlation
Therefore c is your answer :)
To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains
Answer:
394.9 cm
Step-by-step explanation:
The formula for a cone's surface area is A = π r ( r + √r^2 + h^2 ).
r = radius
h = height
The Pythagorean theorem, a^2 + b^2 = c^2, will be needed to find the height.
Plug in the values.
a(unknown)^2 + 6^2 = 15^2
A + 36 = 255
255 - 36 = 189
√189 ≈ 13.7
Surface area formula, plug in the values.
A = 3.14 × 6 ( 6 + √6^2 + 13.7^2 )
*PEMDAS*
A = 3.14 × 6 ( 6 + √36 + 187.69 )
A = 3.14 × 6 ( 6 + √223.69 )
A = 3.14 × 6 ( 6 + 14.95 )
A = 3.14 × 6 ( 20.96 )
A = 3.14 × 125.76
A = 394.8864
*round to nearest tenth*
A = 394.9 cm
Hope this helps! :)
Answer:
61 miles.
Step-by-step explanation:
For to get a mean of 59 the total miles must be 6 * 59 = 354.
Total for 5 days = 46+63+54+70+60 = 293
So on te last day she must bike 354-293 = 61 miles.
Answer:
24 is the mode
Step-by-step explanation:
Mode is the number that is most often seen.
18 is seen 1 time
24 is seen 3 times
25 is seen 1 time
37 is seen 2 times
46 is seen 1 time
24 is the mode because it is seen the most often.
