Create random data for boys and girls ensuring that the data on each column in equal to 10 . Using that data you can answer the questions .
1. Type of favourite fruits
The rest you need the data for .
Step-by-step explanation:
PART A: The area of a circle is radius squared times pi. To estimate the radius, you have to divide the area by pi (estimate 3.14) and then find the square root of the quotient
600/3.14=191.0828...
Square root/radius is about 13 sq feet
PART B:
Now use the pi button instead of 3.14 and do the same thing.
Square root/radius is about 16.9 feet
PART C: Since it's the radius squared and you are doubling it again, it would be radius squared times radius squared, or radius to the fourth power...meaning the area would quadruple.
Reasoning is valid. Area if radius was doubled would be about 3589 feet. ROund to 3600, which divided by 900 is 4
Part 1We are given
. This can be rewritten as
.
Therefore, a=1, b=-18, c=0.
Using the quadratic formula
The values of x are
Part 2Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a
quadratic function. Part 3.The first equation is
.
The second equation is
.
We have
Factoring, we have
Equating both factors to zero.
When the value of x is 6, the value of y is
When the value of x is -3, the value of y is
Therefore, the solutions are (6,38) or (-3,11)
Yes. they may be very small or big but they both can be represented either way.
