What is the area of the figure?
1 answer:
Answer:
88
Step-by-step explanation:
We can divide this into 3 shapes, a square, rectangle, and triangle.
Let's solve the area of each of these shapes and add them all up.
First, let's solve the square.
We know that one side is 4 ft so that means that the other side is also 4ft.
4*4=16
Our area of the square is 16ft^2
Let's solve the rectangle next,
Its length is 12ft and its width is 4ft.
12*4=48
So the rectangle area is 48ft^2
Now for the triangle
Remember that area of a triangle is a=hb/2
Our height is 12 ft and our base is 4ft
12*4=48
48/2=24
Triangle is 24ft^2
That means that we can add them all up
24+48+16=88
88ft^2 or 88

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.
