The area of a circle is 127 square units. What would the circumference of the circle be?
Answer:
Area of the circle = π×r²
127 = 3.14 × r²
=> 127/3.14 = r²
=> 40.44 = r²
=> √40.44 = r
=> r = 6.35
Circumference of the circle = 2πr
= 2×22/7×6.35
=279.4/7
= 39.91
= 40 units

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.4 years with a standard deviation of 0.8 years.
Step 2 of 2: If a sampling distribution is created using samples of the ages at which 38 children begin reading, what would be the standard deviation of the sampling distribution of sample means? Round to two decimal places, if necessary.
Answer:
Step-by-step explanation:
The standard deviation of the sampling distribution of sample means is given by the formula:
standard deviation = population standard deviation / sqrt(sample size)
Here, the population standard deviation is 0.8 years, and the sample size is 38. Substituting these values into the formula, we get:
standard deviation = 0.8 / sqrt(38)
standard deviation ≈ 0.13
Rounding to two decimal places, the standard deviation of the sampling distribution of sample means is approximately 0.13 years.

A garden in the shape of a quadrilateral has two congruent angles. The third angle measures 20° more than twice the measure of one of the congruent angles. The fourth angle measures 25° more than three times the measure of one of the congruent angles. What is the measure of the largest angle of the garden? A 45° B 110° C 146° D 160°
The measure of the largest angle of the garden is A = 160°
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the number of sides of the polygon be = n
Now , since it is a quadrilateral , n = 4
So , the sum of interior angles of a quadrilateral is 360°
Let the measure of the two congruent angles be = x + x = 2x
And , let the third angle be a = 20° + x
Let the measure of the fourth angle be b = 25° + 3x
On simplifying , we get
2x + 20° + x + 25° + 3x = 360°
7x + 45° = 360°
7x = 315°
Divide by 7 on both sides , we get
x = 45°
Now , the measure of b = 25° + 3 ( 45 )°
The measure of angle b = 160°
Hence , the measure of largest angle of the garden is 160°

Find the amount that results from the given investment.
$100 invested at 11% compounded quarterly after a period of 3 years
Answer:
$138.27.
Step-by-step explanation:
Given that it is required to obtain the amount of money that arises from $ 100 invested at 11% compounded quarterly after a period of 3 years, to determine said amount the following calculation must be performed:
X = 100 x (1 + 0.11 / 3) ^ 3x3
X = 100 x (1 + 0.03666) ^ 9
X = 100 x 1.03666 ^ 9
X = 100 x 1.3827
X = 138.27
Thus, the amount that will arise from said investment is $ 138.27.

Answer: 171 attendees
Step-by-step explanation:
I answered another similar question by you earlier, so I really hope you read through this explanation, as I will go far in depth. It's important you learn to do this so as not to simply skate through homework, then struggle with assessment.
For this problem, you have to find something called a unit price.
A unit price is the price in dollars per thing.
In this case, the price in dollars for the whole group is $132 for many things, 66 attendees.
Because 66 attendees costs $132, to find out how much money a single attendee costs, simply divide $132 by 66 to get 2$ for 1 attendee.
With this information, it is very straightforward to determine the number of attendees for $342. Simply divide $342 by $2 to get 171 attendees.
I really hope it helps :) and please, let me know if you want me to explain in more depth, the unit you are currently in is a fundamental part of early math, and it is important you understand it.

If you were to cover a pizza with cheese, how much area, rounded to the nearest whole number, would you need to cover with cheese if the pizza had a circumference of 31.4 inches?
Answer:
79 square inches
Step-by-step explanation:
First, let's find the diameter given the circumference.
\(C=\pi d\) \(d=\frac{C}{\pi }\) \(d= 31.4/3.14\) \(d=10\)Next, we know the the radius is half the diameter, so the radius is 5 inches. Now, we can solve the area of the circle.
\(3.14 * 5^2\) \(3.14 * 25\) \(78.5\) 78.5 ≈ 79 square inchesTherefore, the answer is 79 square inches.

the value of a will be 17 for the given set of data.
What are the properties of a Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Given, KLH is an equilateral triangle.
Since we all know that all angles of an equilateral triangle are equal.
Also From the property of the triangles:
Sum of all angles = 180°
∠K + ∠L + ∠H = 180°
3 * (4a -8) = 180
4a -8 = 60
4a = 68
a = 17

In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average 190 pounds in the summer, including clothing and carry‑on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not normally distributed, especially when the population includes both men and women, but they are not very non‑Normal. A commuter plane carries 22 passengers. What is the approximate probability P that the total weight of the passengers exceeds 4500 pounds? Use the four‑step process to guide your work. Give your answer as a percentage precise to two decimal places. P=___?
The approximate probability P that the total weight of the passengers exceeds 4500 pounds is 10.03%.
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes
Total of 22 is more than 4500 is equivalent to average of 22 is more than \($\frac{4500}{22}\)=204.545
\($$\begin{aligned}P(\bar{x} > 204.545) & =1-P(\bar{x} < 204.545) \\& =1-P\left(\frac{\bar{x}-\mu}{\sigma / \sqrt{u}} < \frac{204.545-195}{35 / \sqrt{22}}\right) \\& =1-P(z < 1.2792) \\\end{aligned}$$\)

Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy. If there are no possible solutions, submit an empty answer.
Answer:
The maximum amount of apples she could buy is 7
Step-by-step explanation:
3 mangos would be 4.50 dollars. Subtract that from her current amount of money (20 dollars). You would get 15.5 dollars. Then, find how many apples she can buy with 15.5 dollars. You can't buy 8 because that would be above 15.5. So do the next smallest amount, 7.

the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.
A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

Graph the point on the graph.
Answer:
see below
Step-by-step explanation:
To graph this equation, start at the origin (0,0) since there is not y-intercept.
Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.
Because the rise (up and down, numerator) is 1, we know that we will go up one unit.
The run (side to side, denominator) is 4, so we will go to the right 4 units.
This makes the first point (4, 1).
