-20 because 40 is a positive and spent is negative
<h3><u>Solution: </u></h3>
Overall<u> </u>CP of each fan = ₹1200 .
One is sold at a loss of 5% .
- ( This means if CP is ₹100, SP is ₹95 ) .
• Therefore,When CP is ₹1200 , Then SP is ₹ 1140.

Also,Second fan is sold at a profit of 10% .
- It means , If CP is ₹100 , SP is ₹110.
Therefore , When CP is ₹1200 , Then SP is ₹1320.
<u>• We need to find the combined CP and SP to say whether there was an overall profit or Loss.</u><u>.</u>
- Total CP = ₹ 1200 + ₹ 1200 = ₹ 2400.
- Total SP = ₹ 1140 + ₹ 1320 = ₹ 2460.
Since total SP > total CP , A profit of ₹ ( 2460 - 2400 ) or ₹60 has been made ..

Answer:
y = (1/3)x + 4
Step-by-step explanation:
Two points on this line are (0, 4) and (3, 5).
As we move from the first point to the second, x increases by 3 and y increases by 1. Thus, the slope, m, of the line is m = rise / run = 1/3.
Use the slope-intercept equation: y = mx + b.
If we use the data from the point (0, 4), we get:
4 = (1/3)(0) + b, so that b = 4. The desired equation is y = (1/3)x + 4.
Answer:
Step-by-step explanation:
From the given data
we observed that the missile testing program
Y1 and Y2 are variable, they are also independent
We are aware that
have
distribution with 1 degree of freedom
and
has x^2 with 2 degree of freedom

Since we have to find the density formula

We use method of transformation

There inverse function is 
We derivate the fuction above with respect to u

Therefore,

11+5=16 3x2= 6 8x1= 8 so add it together, 16 + 6 + 8 = 30.
