Answer:

y = 5

multiply:

2 (-1) + y = 3 → -2 + y = 3

rearrange:

y - 2 = 3

add to both sides:

y - 2 + 2 = 3 + 2

simplify:

y = 5

I hope this helps! Sorry if it's the wrong answer! (′д｀σ)σ

Since the graph is a straight line, its equation is of the form;

$y = mx + c$
Where m is the slope and c is the y intercept

We can use any two points on the straight line to find the value of m and c.

Let us use (0,30) and (4,150)

$m = \frac{150 - 30}{4 - 0}$
This simplifies to,

$m = \frac{120}{4} = 30$
Let us substitute the value of m to obtain,

$y = 30x + c$
Substitute any of the points to find c. It is easier to use (0,30).

$30 = 30(0) + c$
$c = 30$
The equation of the graph now becomes,

$y = 30x + 30$
So in 10 weeks Ben will collect,

$y = 30(10) + 30$
$y = 300 + 30$
$y = 330$
Ben will collect 330 papers.

You can also use any two points to find the equation of this line.

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
