Answer:
y = x - 4
Step-by-step explanation:
The standard equation of a line is y = mx+b
m is the slope
b is the y intercept
Get the slope
Using the coordinate points (4, 0) and (0, -4)
m = -4-0/0-4
m = -4/-4
m = 1
Since the line cuts the y axis at y = -4, the y-intercept b = -4
Get the equation;
Since y = mx+b
y = 1x + (-4)
y = x - 4
This gives the required equation
Two sandwiches divide by three brothers is:
2/3
So each brother gets two thirds of a sandwich.
Answer:Jason’s salary depends on the number of hours he works. The independent variable is the number of hours and the dependent variable is salary. Let x = the number of hours worked Let y = Jason’s salary The set of ordered pairs {(1, 10), (2, 20), (3, 30), (4, 40), (5, 50)} can be used to represent the function, assuming Jason earns $10 per hour The number of hours the train takes depends on the distance. The distance is independent and the number of hours is dependent. {(2,20)(4,40)(6,60)(8,80)(10,100)} For every 2 hours it takes 20 miles. The amount of money depends on the time worked.
Step-by-step explanation:
Let T = the distance, in miles, a tire lasts
T ~ N(70000,4400<span>²</span>)
P(T
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
75000)
= P(Z
![\geq \frac{75000 - 70000}{4400}](https://tex.z-dn.net/?f=%20%5Cgeq%20%5Cfrac%7B75000%20-%2070000%7D%7B4400%7D%20)
)
= P(Z
![\geq \frac{25}{22}](https://tex.z-dn.net/?f=%20%5Cgeq%20%5Cfrac%7B25%7D%7B22%7D)
)
≈ P(Z
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
1.14)
= 1 - P(Z < 1.14)
≈ 1 - 0.8729
= 0.1271
