Answer:
This line can be represented by the line y = 3/4x + 2.
Step-by-step explanation:
The slope is identified as the m in y = mx + b. The slope is the rise/run of your line (AKA how many units it goes upwards/downwards and then goes to the right/left to meet the second given point).
In this case, the line rises 3 units from 2 to 5, and then goes to the right by 4 units to meet the coordinate (4, 5).
B in the equation refers to the y-intercept, or where the line intersects/crosses the y-axis. In this case, it is the coordinate (0, 2).
Finally, x is irrelevant and is placed in the equation for no reason (at least that I am aware of in my several years of high school math).
Therefore, your final equation is y = 3/4x + 2.

Let's assume that the entire are in the distribution curve is 1
Given
Time taken from 0s to 30s = 30s - 0s = 30s
To find height of the distribution?
Let H = the height of the distribution
Based on the above assumption;.
H * 30 = 1 --- make H the subject of formula
H = 1/30
H = 0.0333
Hence, the calculated height of the distribution is 0.0333
Answer:
Step-by-step explanation:
in order to solve this system of equation we would say that let
3x+2y=-8........................................................ equation 1
1 x - y = -1 ........................................................ equation 2
from equation 2
1 x - y = -1 ........................................................ equation 2
x = -1 + y....................................... equation 3
substitute for equation 3 in equation 1
3x+2y=-8........................................................ equation 1
3( -1 + y) + 2y = 8
-3 + 3y +2y = 8
collect the like terms
-3 + 5y = 8
5y = 8 + 3
5y = 11
divide both sides by the coefficient of y
5y/5 = 11/5
y = 2.2
put the value y = 2.2 into equation 3
x = -1 + y....................................... equation 3
x = -1 + 2.2
x = 1.2
therefore th value of x is 1.2 and y is 2.2
Answer:
40
Step-by-step explanation:
if the ratio from men to woman is 4:5 and men are 32 that means w need to find a way to get to 32 using 4 and 8 x 4 is 32. so if we use 8 to get to 32 we need to use 8 on 5 aswell for it to be an equal ratio.
