Answer: It is true that required total sample size is less than the pilot sample already taken.
Step-by-step explanation:
Since we have given that
N = 30
Margin of error = E = 30
Standard deviation = 60
At 95% level of significance,
z = 1.96
So, the value of sample would be

So, it is true that required total sample size is less than the pilot sample already taken.
To find square numbers, you multiply the number by itself.
For example:
5 x 5 = 25
10 x 10 = 100
Answer:
- x-intercept: -2
- y-intercept: 4
Step-by-step explanation:
The function is written in slope-intercept form, so the constant (4) is the y-intercept.
The x-intercept is found by solving for x when y = 0.
0 = 2x +4
0 = x +2 . . . . . divide by 2
-2 = x . . . . . . . the x-intercept
The x-intercept is -2; the y-intercept is 4.
using the equation for the transformation:
(x+1, 3y)
add 1 to very X and multiply y by 3
so (-2,0) becomes (-1,0)
(-2,3) becomes (-1,9)
(-5,1) becomes (-4,3)
new coordinates are (-1,0) (-1,9) (-4,3)
you don't have an image attached, so to see if they are congruent, the sides need to stay the same lengths and the angles need to stay the same, from the coordinates of the new triangle, I would say they are not congruent
Answer:
Step-by-step explanation:
let the price of one shirt be x and one pant be y
Eli--> x+y=600------eq1
Simin-->4x+2y=1500-----eq2
Solve both the equations
multiply eq1 x 4= 4x+4y=2400
now subtract ew2 from 1
you will get y=450 and x=150
so price of one shirt=150 kr
