Answer:
68.26% of the parts will have lengths between 3.8 in. and 4.2 in.
Step-by-step explanation:
The lengths of a lawn mower part are approximately normally distributed
Standard deviation =
We are supposed to find What percentage of the parts will have lengths between 3.8 in. and 4.2 in . i.e. P(3.8<x<4.2)
Formula :
At x = 3.8
Z=-1
Refer the z table for p value
p value =0.1587
At x =4.2
Z=1
Refer the z table for p value
p value =0.8413
P(3.8<x<4.2)=P(x<4.2)-P(x<3.8)=0.8413-0.1587=0.6826
So, 68.26% of the parts will have lengths between 3.8 in. and 4.2 in.
Answer:
Step-by-step explanation:
Given
ET = 120 V
, R = 30 Ω,
XL = 40 Ω.
To find = IR=?
as in circuit inductor and resistor are parallel so ET =EL = ER = 120V
IR = current through resistor = IR = ER/ R
= 120V /30Ω.
= 4 ampere.
the eqaution of a line is:
y = mx + b
where,
y = y - coordinates
m = slope
x = x - coordinates
b = intercepts
so with the values given as:
m = 4
b = 12
so the equation of line with the given values is
y = 4x + 12
