Answer:
(a) mean = 377.5ml. standard deviation = 4.33
(b) 0.333
(c) 384.25 ml
Step-by-step explanation:
(a)The mean:
The standard deviation:
(b)
(c)P(x > m) = 0.95
So the volumn of shampoo should be 384.25ml to exceed 95% of containers.
Answer:
1 solution
Step-by-step explanation:
A system of linear equations has no solution when the graphs are parallel.
Answer:
y=2x+5
Step-by-step explanation:
The equation of a line in slope intercept form is written as: y=mx +b where m is the slope and b is the y-intercept.
Taking point (-1,3) , m= 2 and imaginary point on the line, (x,y) then ;
m=change is y-coordinates/change in x-coordinate
m=Δy/Δx
m=y-3/x--1
2= y-3 / x+1
2(x+1) = y-3
2x +2 =y-3
2x=y-3-2
2x=y-5
<u>y=2x+5 is the equation.</u>
Answer:
q= -4
Step-by-step explanation:
First, simplify 4x+2y=5
2y=-4x+5
y=-2x+5/2
q+2 has to equal to -2
q = -4
Answer:
4 and 5
Step-by-step explanation:
We know that.
√16 < √21 <√25
⇒4 < √21 < 5
Hence √
21 lies between 4 and 5
