Answer:
4/3
Step-by-step explanation:
To the power of negative one just means 1 divided by and 1 divided by 3/4 is just 4/3
The <u>correct answer</u> is:
It is not a very strong fit.
Explanation:
The r-value, or correlation coefficient, tells us how closely our model fits the data.
The r-values range from -1 to 1. -1 is a perfect fit of a decreasing model; 1 is a perfect fit of an increasing model. 0 is no fit at all.
Since our r-value is 0.29, this is much closer to 0 than it is to 1 or -1; this means it is not a very strong fit.
X - number of months ( 1, 2 or 3 );
A function is:
f ( x ) = 50 x + 200
A reasonable domain is:
x ∈ { 1, 2, 3 }
The range is:
y ∈{ $250, $300, $350 }
Answer:
After one unit is sold, Becky will break-even.
Step-by-step explanation:
Giving the following information:
Fixed costs= $1
Unitary variable cost= $21
Selling price= $22
<u>The break-even point is the number of units required to cover the fixed costs after deducting from the selling price the variable components. At this point, net income is zero</u>.
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 1 / (22 - 21)
Break-even point in units= 1
After one unit is sold, Becky will break-even.
It does not say simple or compound interest.
Simple interest is rarely used these days, so assume compound.
Use the standard formula:
future value = present value*(1+rate/n)^(nt)
n=number of times interest is compounded per year (=1)
t=number of years
Plugging values,
200=100(1.09)^t
1.09^t = 2
take log
t(log(1.09))=log 2
t=log(2)/log(1.09)=0.6931/0.08618=8.04 years.
