If x^2 + xy = 20 and dx/dt = -4 when x = -5 and y = 1, what is dy/dt

SpyIntel [72]

Answer:

3.2

Step-by-step explanation:

x² + xy = 20

Take the derivative with respect to time:

2x dx/dt + x dy/dt + y dx/dt = 20

(2x + y) dx/dt + x dy/dt = 20

Given x = -5, y = 1, and dx/dt = -4:

(2(-5) + 1) (-4) + (-5) dy/dt = 20

(-10 + 1) (-4) − 5 dy/dt = 20

36 − 5 dy/dt = 20

5 dy/dt = 16

dy/dt = 3.2

1. Consider the chance experiment of selecting an adult at random from the sample. The number of credit cards is a discrete rand

Fantom [35]

Answer:

See the explanation below.

Step-by-step explanation:

Assuming the distribution table given:

X ( Number od Credit Cards) Relative frequency

0 0.26

1 0.17

2 0.12

3 0.10

4 0.09

5 0.06

6 0.05

7 0.05

8 0.04

9 0.03

10 0.03

We can create the histogram for this data using the following code in R:

> x<-c(0,1,2,3,4,5,6,7,8,9,10)

> freq<-c(0.26,0.17,0.12,0.10,0.09,0.06,0.05,0.05,0.04,0.03,0.03)

> x1<-c(rep(0,26),rep(1,17), rep(2,12),rep(3,10), rep(4,9),rep(5,6),rep(6,5),rep(7,5),rep(8,4),rep(9,3),rep(10,3))

> hist(x1,breaks = x,main = "Histogram", ylab = "%", xlab = "Number of credit cards")

And we got as the result the figure attached. We see a right skewed distribution with majority of the values between 0 and 3
