Answer:
Step-by-step explanation:
Area of a rectangle is represented as;
A = length * width
Given
Area = 3/5 m²
Width = 2/5 m
Required
Length = x
Get the length;
From the formula
L = A/W
L = 3/5 ÷ 2/5
L = 3/5 × 5/2
L = 3/2 m
Hence the length of the rectangle is 3/2 m
Take the ratio of the length to the width as shown;
L/W = 3/2÷2/5
L/W = 3/2 * 5/2
L/W = 15/4
L = 15/4 W
Hence the length is 15/4 times greater than the width
Hey there!!!
Equation given :
p ( x ) = 3x² + 4x + 5
Find p ( 2x )
In order to solve this, we will have to substitute the value 2x instead of x
Hence,
... p ( 2x ) = 3 ( 2x )² + 4 ( 2x ) + 5
... p ( 2x ) = 3 ( 8x² ) + 8x + 5
... p ( 2x ) = 24x² + 8x + 5
As we know I ( x ) = p ( 2x )
The value of I(x) = 24x² + 8x + 5
Hope my answer helps!
Answer:
Test statistic Z = p diff/std error = 2.3333
p value one tailed = 0.009815
Step-by-step explanation:
Given that in a survey conducted by a website, employers were asked if they had ever sent an employee home because they were dressed inappropriately.
Sample size n = 2755
Sample favourable x = 967
Sample proportion p = 
(right tailed test at 5% significance level)
p difference = 0.0210
Standard error assuming H0 is true is 
Test statistic Z = p diff/std error = 2.3333
p value one tailed = 0.009815
Since p <0.05 we reject null hypothesis.
