Answer:
It's the the 4th one. 6.3.3
Answer:
5.32
Step-by-step explanation:
It took me a while to figure this out myself, here is how I found the answer:
The question gives sample number(80) and the standard error(0.595).
To get the standard error number they use this equation:
So to find the standard deviation, take and times it by the standard error to get the answer.
x 0.595 = 5.321841786449499
And then round to the nearest hundredth: 5.32
Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm
These are the steps and the answer
C because
3/5 * 2 both numbers so that .... 3*2= 6 and 5*2= 10 and those two numbers 6/10 = C when you want to solve a proportion just times in by both numerator and denominator so that they equal another number.
