Answer:
24
Step-by-step explanation:
The area is calculated by multplying radius (half of diameter) by itself and then with number pi
the area for this circle is given as
144π m^2
144 is the squared form of 12 if the radius is 12 the diameter is 24
For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error
Answer:
The size of the sample 'n' = 2401
Step-by-step explanation:
Step:1
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
[tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
we know that the proportion
[tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]
Step:2
The margin of error is determined by
[tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]
[tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
Final answer:-
The size of the sample 'n' = 2401

And orange falls of a display at a store and rolls 5 meters in 2.5 seconds.What is the average speed of the orange
Answer:
The orange moves at 2M/s
5/2.5=2
2meters/secon
The average speed of the orange is 2 m/sec.
Given that, orange falls off a display at a store and rolls 5 meters in 2.5 seconds.
We need to find the average speed of the orange.
What is the average speed formula?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speeds, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
The formula for average speed is given as:
Average Speed = Total distance covered ÷ Total time taken
Now, average speed=5/2.5=2 m/sec.
Therefore, the average speed of the orange is 2 m/sec.

Brenda bought three time more black fabric than red fabric. She bought 72 inches of red fabric. If fabric costs 7.25 per yard, how much did Brenda spend on fabric
Answer:
$58 dollars
Step-by-step explanation:
Step 1: Find price of Red Fabric. So Brenda bougt 72 inches. So we convert that to amount of yards.(36 inches=1 yard). So the equation is 72/36=2 yards. Then do 7.25x2= $14.50 for red fabric.
Step 2: Find price of Black Fabric. So Brenda bought 3 times more the red favric. So she 216(72x3 is how I got the number). Now divide 216 by 36. That equals 6. So now do 7.25x6= $43.50
Step 3: Add the prices. So now add the price of the red and black fabric to find the answer. So $43.50 + $14.50= $58
Hence, the answer is $58 dollars.

–5 + 20
Evaluate the expression and write the answer below. Write only a number, either positive or negative. No letters
Answer:
-15
Step-by-step explanation:
because -5 + 20 = -15.
The coach needs 15 negative players to join the negative team in order to get 20 players (which would make the teams even)
1) Solve for Side A
2) Solve for Angle B
Answer:
1) 42.51
2) 39.76
Answer:
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]

A) x + 2 y = 1
C) x - 2y = 10
B) x-1= 2
D) x – 2y=
Answer:
B)
Step-by-step explanation:
y-intercept = -2
slope = 1
in slope-intercept form the line would be: y = x - 2
if we subtract 'x' from each side we get:
-x + y = -2
we don't want to leave 'x' as negative so we can multiply each term by -1 to get:
x - y = 2

For what value of x is line / parallel to line m in this figure?
Answer:
132
Step-by-step explanation:
The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180
This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180
So x = 180 - 48
180 - 48 = 132
Hence, x = 132

Divide both sides by R.
[tex] \dfrac{P}{R} = I^2 [/tex]
Switch sides.
[tex] I^2 = \dfrac{P}{R} [/tex]
Take the square root of both sides.

The table shows the heights of the 5 tallest mountains in the world. Find the mean, median, and range
of the heights.
Answer: The median is 28208 the mean is 28234.6
Step-by-step explanation:
The mode is the number that is repeated the most there can be more than one mode.
Answer:
All in ft
Mean: 28,235
Median: 28,208
Range: 1,245
Step-by-step explanation:
Mean is the sum of the elements divided by the number of elements.
(29035+28250+28208+27890+27790)/5 = 28235
Median is the element in the exact middle of the set (if there is an even number of elements, take the average of the two elements in the middle).
After rearranging the numbers, we can see 28208 is in the exact middle.
27790 27890 28208 28250 29035
Range is the difference between the smallest and largest number in the set.
29035-27790=1245
