In calculus, we went over the subject of implicit differentiation. I feel pretty solid on how to do it, except when they give th

e problem with \frac{dx}{dt} or \frac{dx}{dy} instead of your standard \frac{dy}{dx}
How do you do these kinds of problems?

The same way.

\dfrac{dy}{dx} means it's derivative of function y with respect to x

\dfrac{dx}{dt} means it's derivative of function x with respect to t

\dfrac{dx}{dy} means it's derivative of function x with respect to y

For question 1:
1% = 120 ÷ 100 = 1.2
15% = 1.2 × 15 = 18
So, 15% of 120 is 18

For question 2:
68.4 ÷ 72 = 0.95
0.95 × 100 = 95%
So, the percentage is 95%

For question 3,
1% = 12.5 ÷ 8 = 1.5625
100% = 1.5625 × 100 = 156.25
So, 8% of 12.5 is 156.25.

For question 4,
1% = 48 ÷ 40 = 1.2
100% = 1.2 × 100 = 120
So, 40% of 48 is 120.

For question 5,
1% = 195 ÷ 100 = 1.95
62.5% = 1.95 × 62.5 = 121.875
So, 62.5% of 195 is 121.875

David's gasoline station offers 4 cents off per gallon if the customer pays in cash and does not use a credit card. Past evidenc
shusha [124]

Answer:

0.6535

Step-by-step explanation:

Given that during a one-hour period twenty-five customers buy gasoline at this station.

Let X be the no of persons out of these 25 who pay by cash.

X has two outcomes and each trial is independent of other.

Hence X is binomial (n=25, p=0.40)

Required probability

= P(X\geq 10)\\=P(10)+P(11)+...+P(25)\\=\Sigma_{10}^{25}  25Cr (0.4)^r (1-0.4)^{25-r}

=0.6535
