Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope and it's y-intercept and then write it in the following form:
The slope of the line we get from first two points:
thus we have
we find by putting the point into the function:
Thus we have
Now we have to find where this line intersects with ; to do this we just substitute with :
<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting into :
Thus the solution to the system is
which is option 4.
Answer:
The weight corresponding to which weight will be larger than 14% of times equals 427.635 grams.
Step-by-step explanation:
We need to find the value of weight that corresponds to 14% of area under the normal distribution curve
It is given that
Using standard normal distribution tables we find value of Z corresponding to 14% of the area as -1.080
Thus using the standard equation
A) 1.53
B) 1.26
I'm pretty sure that is the answer
Well because the real estate agent is taking 7%, the cost of 93% of the house should be 175000(because that's how much the family will get)
Thus 0.93X=175000
X=188172.04
