Answer:

B

Step-by-step explanation:

Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have

\dfrac {7 \frac12} {10} = \dfrac a4

We can cross multiply to get that

10a = 30, \text{so } \boxed{a=3}

The probability that he or she owns a credit card given that the student is a freshman is 0.63.

<h3>How to calculate the probability?</h3>

Number if freshman with credit card = 38

Total number of freshman = 60

Therefore, the probability that he or she owns a credit card given that the student is a freshman will be:

= 38/60

= 0.63

Therefore, the probability that he or she owns a credit card given that the student is a freshman is 0.63.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
nydimaria [60]

Answer:

Step-by-step explanation:

As you can see, this is a quadratic equation and if you were to graph this you would see that it is a parabola that opens down because of the negative leading coefficient (-34). The maximum profit would be at the vertex, of the graph. Therefore, we need to find the value of "y" when "x" is the line of symmetry. We find this by  x=-b/(2a) where a = -34 and b = 1542:

x=-1542/(2)(-34)

x=-152/-68

x=152/68  

We put this value of "x" into the original formula to find out the value of "y":

y=-34x^2+1542x-10037

y=(-34)(1542/68)^2+1542(1542/68)-10037

y= -17483.5588235 + 34967.1176471 -10037

y=7446.5588236

Therefore, the maximum profit would be $7446.56.

Hope this helps!

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
tino4ka555 [31]

Answer:

4x^{2}-16x+8

Step-by-step explanation:

4(x - 2)(x - 2) - 8 = 4(x^{2} - 4x + 4) - 8 = 4x^{2} - 16x + 16 - 8 = 4x^{2} - 16x + 8.
