There are all parallelograms.
To find their area we need to use only one formula.
A=base*height
Everything is given, so
1) A=b*h=5.3*4=21.2 km²
2) A=b*h= 11*10.7= 117.7 mi²
3) A=b*h= 10.5*7.9 =82.95 mi²
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
Answer:
I have labeled the arcs AB and CD. The measure of angle x is 60°
Step-by-step explanation:
The measure of angle x is ½(mAB + mCD)
Answer:
The population parameter is the average wait time for all the bank's customers.
Step-by-step explanation:
The population parameter is a numerical value that defines a specific characteristic of the population. For example, the population mean describes the average value of the population, the population variance describes the variance of the population and the population proportion describes the proportion of a certain variable in the population.
The sample statistic is a numerical value that defines a specific characteristic of the sample that is selected from the population. The examples of sample statistic are, sample mean, sample variance and sample proportion.
In this case it is provided that the bank manager wants to know the average amount of time customers of his bank have to wait in line.
The experiment involved, asking 300 customers about their average wait time at the bank.
So, the parameter under study is the mean time the customers have to wait at the bank.
Hence, the population parameter is the average wait time for all the bank's customers.
The expression representing the perimeter is 6x + 39
x = 3. 8
<h3>What is the perimeter?</h3>
The formula for perimeter of a rectangle is given as;
Perimeter = 2 ( length + width)
From the image shown, we have that:
- length = 2x
- width = x + 13
Now, let's substitute the value
Perimeter = 2 ( 2x + x + 13)
collect like terms
Perimeter = 2 ( 3x + 13)
Expand the bracket
Perimeter = 6x + 39
If perimeter = 62
62 = 6x + 39
6x = 62 - 39
6x = 23
x = 23/ 6
x = 3. 8
Thus, the expression representing the perimeter is 6x + 39
