Answer:

2nd choice:

x int: 11/6

y int: 11/2

Step-by-step explanation:

put 6x + 2y = 11 into y = mx+b form to find y intercept. (b stands for the y int)

you get y = -3x + 11/2.

now you can graph with this.

plug 0 in for y and solve for x to find x int

0 = -3x + 11/2 then solve

Mr. I does a job in x hours while Mr. L can do it in y hours. How much of the job could they do together if they were to work fo

dimulka [17.4K]

Answer: Work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

Explanation:

Since we have given that

Number of hours Mr. I does a job = x hours

Number of hours Mr. L does a job = y hours

Work done by Mr. I is given by

$\frac{1}{x}$

Work done by Mr. L is given by

$\frac{1}{y}$

Work done if they do together is given by

$\frac{1}{x}+\frac{1}{y}\\\\=\frac{x+y}{xy}$

Work done if they work together for k hours is given by

$\frac{x+y}{xy}\times k\\\\=\frac{k(x+y)}{xy}$

Hence, work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

Answer:

Option d is right

Step-by-step explanation:

Let X be the time spent on a treadmill in the health club

Given that research shows that on average, patrons spend an average of 42.5 minutes on the treadmill, with a standard deviation of 5.4 minutes

Also given that X is normal

the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.

$= P(30$

round off to two decimals tog et

the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill is 0.31

Hence option d is right
