The car cost $4,155 and she has $1,575 so $4,155-$1,575=$2,580as the balanced owed if she borrows the rest from her parents and has a one year to pay it off it will be paid off because her payments are $225 a month for one year at 225x12=$2,700 its a little over but it will be paid off
Answer: C. 119.7°
Step-by-step explanation:
edge2020
Answer:
15.39%
Step-by-step explanation:
Step 1
Find the z-value associated to the given datum x, in this case x = 28 mpg
<em>z is given by the formula
</em>
where
is the mean of the distribution and
is the standard deviation. In this case,
Step 2
Locate the z-value in the table of z-values of the normal distribution.
(See table attached) and read the number corresponding to this z-value. In this case is highlighted in the table and its value is 0.34614.
<em>This numbers gives us the % of vehicles with a mpg between 0 and 28.
</em>
Step 3
As we know that the total area under the curve for z > 0 is 0.5, then we have to subtract 0.34614 from 0.5 to obtain the % of cars with a mpg greater than 28 mpg.
0.5 - 0.34614 = 0.15386
so, the % of 2016 vehicles that have better gas mileage than the Beetle's gas mileage is 15.39 % (rounded to two decimals)
U would factor out the nine the largest degree is 9
