Answer:
865
Step-by-step explanation:
We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.
Now we have the following formula:
n = [z / E] ^ 2 * (p * q)
where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.
Replacing these values we are left with:
n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]
n = 864.36
865 by rounding to the largest number.
Given:
Dimensions of Kendra's yard are 24.6 feet by 14.8 feet.
To find:
The area of her yard.
Solution:
Let as consider,
Length of yard = 24.6 ft
Width of yard = 14.8 ft
We know that,
Area of a rectangle = Length × Width
Using the above formula, we get the area of her yard.
Area of her yard is 364.08 ft² and without including the units ft², we get 364.08.
Therefore, the area of her yard is 364.08.
Answer:
7
Step-by-step explanation:
No. of pizza Ronnie stacked = 0.25 × 40
= 10
No. of pizza Mack stacked = 9
No. of pizza Kim stacked = 
× 40
= 14
No. of pizza Ada stacked = 40 - 10 - 9 - 14
= 7
Answer:
$132,000 X .0085 = $1,122 / 360 = $3.1166 X 164 = $511.13
One mill is one dollar per $1,000 dollars of assessed value.
In our case 8.5 mills equivalent to 0.0085.
So to get the assessed value for one day
we will get
$132,000 X .0085 = $1,122 / 360 = $3.1166
Now we have the value for one day,
For June 14, we will calculate the days from January 1st to date
total days are 164. i.e. 5*30+14 = 164
Finally, the seller owes
$3.1166 * 164 = 511.13
