Total distance = sum of the distances run:60 km + 45km = 105 km
Displacement: difference between iniital position and final position: 0 + [60km - 45km] = 15 km
Answer:
Solution:-
Frequency Distribution Frequency Mid values F*M
0 - 10 8 5 40
10 - 20 x 15 15x
20 - 30 10 25 250
30 - 40 11 35 385
40 - 50 9 45 405
_____________________________________________________
Σf = 38+x Σfm = 1080+15x
______________________________________________________
Given Mean = 25.2
Mean = Σfm/Σf
25.2 = 1080+15x/38+x
25.2 × (38+x) = 1080+15x
957.6+25.2x = 1080+15x
25.2x - 15x = 1080 - 957.6
10.2x = 122.4
x = 122.4/10.2
x = 12
Missing frequency = 12 Answer
9514 1404 393
Answer:
y = 2/3x -20/3
Step-by-step explanation:
The perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line:
-1/(-3/2) = 2/3
You can use the point-slope form to write the equation of that perpendicular line.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +2 = 2/3(x -7) . . . . . the equation of the perpendicular line
__
This can be put into slope-intercept form by solving for y and simplifying.
y +2 = 2/3x -14/3
y = 2/3x -20/3
Answer:
The circle graph is attached.
Step-by-step explanation:
a) Data and Calculations:
Monthly Expenses for a Family Budget
Expenses Percentage Degree
Housing 35% 130° (360° * 35%)
Food 14% 50° (360° * 14%)
Clothing 17% 60° (360° * 17%)
Entertainment 12% 40° (360° * 12%)
Auto 22% 80° (360° * 22%)
b) The result shows that Housing expense took more than one-third of the circle with auto expenses occupying the next biggest chunk of the circle. Clothing came third to occupy one-sixth of the circle, with food and entertainment trailing behind with less than one-sixth of the circle respectively.
Answer:
Step-by-step explanation: No, Gavin is not correct because 284.42 is less than 400 the equation is 200(1+0.09/2)^8 when solved you get 284.42 which is not enough.
Step-by-step explanation:
simplifying this
Ok so do 0.09/2 which is 0.045 then add 1 so you get 200•1.045^8 then you do 1.045^8= 1.422100.... so I did 1.422100•200 to get the final answer of 284.42
