Answer:
The probability that a family spends less than $410 per month
P( X < 410) = 0.1151
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given mean of the population = 500 </em>
<em>Given standard deviation of the Population = 75</em>
Let 'X' be the variable in normal distribution
       
<em>Given X = $410</em>
<em></em> <em></em>
<em></em>
<u><em>Step(ii):-</em></u>
The probability that a family spends less than $410 per month
P( X < 410) = P( Z < - 1.2 )
                   =  0.5 - A( -1.2)
                  = 0.5 - A(1.2)
                 = 0.5 - 0.3849  ( ∵from normal table)
                 = 0.1151
<u>Final answer:-</u>
The probability that a family spends less than $410 per month
P( X < 410) = 0.1151

Answer:
y = 3/5 x+3
Step-by-step explanation:
two points on the graph
(-5,0) (0,3)
the y intercept is 3  (this is where it crosses the y axis)
the slope is
change in y     0 to 3            up 3
------------------  = -------------- =  -------        =   3/5
change in x      -5 to 0             right 5
we can tell the slope is positive because it goes from bottom left to top right
a negative slope goes from top left to bottom right
slope intercept form is
y=mx+b
y = 3/5 x+3

Answer:
10 times less
Step-by-step explanation:
In the number 356, 740, the 4 is in the tenths place. 
In 763,450, the 4 is in the hundredths place.
100/10 = 10
