The mean is the average of the numbers, so if x = all 11 numbers added together, then you have the equation:
x / 11 = 7, so x = 77 (this is all of the numbers added together)
if the number 13 is removed, the equation becomes:
(77 - 13) / 10 = M (M is the new mean)
so the new mean is 6.4
Answer:
we have P(x) = mx + 1
Step-by-step explanation:
Allow me to revise your question for a better understanding:
<em>The pressure at sea level is 1 atmosphere and increases at a constant rate as depth increases. When Sydney dives to a depth of 23 meters, the pressure around her is 3.3 point, 3 atmospheres. The pressure p in atmospheres is a function of x, the depth in meters.</em>
My answer:
Given:
At O meter the the pressure is 1 (0, 1)
At 23 meters the the pressure is 3.3 (23, 3.3)
From that, we can form a linear equation with the standard form:
P(x) = mx + b (1)
The slope of (1) is:
<=> P(x) = 0.1x + b
Substitute the point (0, 1) into (1) we have:
1 = 0.1*0 + b
<=> b = 1
So we have the equation of this line will be: P(x) = mx + 1
Answer:
376 squared inches for the hole bird house, 60 for the side with the whole.
Step-by-step explanation:
1 side is 60 inches squared, another is 48 inches squared, and another is 80 inches squared, and there are two of each side so you get 120+96+160= 376.
It is true that bad road condition does have a direct impact
on the physical, emotional and economic aspects to the family, the community
and the country. Bad roads can cause accidents which directly impacts a person
physically. Mentally it is very stressful for a person to drive on bad roads. He
or she has to be extra careful regarding potholes and other damages that have
happened to the road. Economically bad roads can be the reason for price rise
of products as time required to move a product via road is more. Also the cost
of transport increases drastically.
