Answer:
Complete the table :
Likes hamburgers Does not like hamburgers Total
Likes burritos 29 41 70
Does not like burritos 81 54 135
Total 110 95 205
54 do not like both hamburgers and burritos
Hence % = (54/205) * 100 = 26.34 %
marginal relative frequency of all customers that like hamburgers
= 110/205
= 22/41

Answer: d. s=16-t²
Step-by-step explanation: the answer is s=16-t², because for this case is really important to keep in mind which is the value with the quadratic expression, when we have a quadratic expression the graphic representation will be a parabola, in a parabola you will find a point that never change which is constant in the diagram.
also keep in mind that the values which are placed in the axis of the ordinates are the independent variables and in parabola the quadratic values are placed in the axis of the ordinates , and for this case is t² because of the quadratic expression, then we can find that t² is the independent variable and s is the dependent variable.

Answer:
8 quarters and 14 dimes
Step-by-step explanation:
This situation has two unknowns - the total number of dimes and the total number of quarters. Because we have two unknowns, we will write a system of equations with two equations using the two unknowns.
• 
is an equation representing the total number of coins
• 
is an equation representing the total value in money based on the number of coin. 0.10 and 0.25 come from the value of a dime and quarter individually.
We write the first equation in terms of q by subtracting it across the equal sign to get 
. We now substitute this for d in the second equation.
After simplifying, we subtract 2.2 across and divide by the coefficient of q.
We now know of the 22 coins that 8 are quarters. To find the number of dimes, we subtract 8 from 22 to get 14 dimes.
The slope is is 2
