Using the mean formula, we will add the two values and divide the result by 2 to determine the mean of the two values.
What is mean?The average of a group of variables is referred to as the mean in mathematics and statistics.
There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
So, to find the mean of 2 values:
Mean formula: Sum of the terms / Number of terms
Now, using the formula, to obtain the mean of 2 values, we will get the sum of the 2 given values and divide it by 2.
Therefore, using the mean formula, we will add the two values and divide the result by 2 to determine the mean of the two values.

Match each type of event with its probability. Unlikely event, 10greater than 0 and less than 0.50.5greater than 0.5 and less than 1Neither likely nor unlikely event likely event
Answer:
Unlikely = greater Than 0 ; less than
Likely = greater than 0.5 ; less than 1
Neither likely nor unlikely = 0.5
Step-by-step explanation:
Probability values usually range between standardized values between 0 and 1. With values closer to 1 depicting greater possibilities of an event. Probability value of zero means certain and probability value of 0 zero means.impossible.
Using this standardized values :
An unlikely event is more of not occurring than occurring (that is the event has higher chances of not happening) ;
Hence; We can categorize unliky events to range from below the mid value to greater Tha.n 0
Unlikely event : greater Than 0 ; less than 0.6
Events with probability above the mid value of 0.5 have higher chances of occurring (greater likelihood) hence, Probability is greater than 0.5 but less than 1.
Neither likely nor unlikely event will take the boundary point between likely and unlikely = 0.5

Given:
A circle with center O, LN and MP are two diameters.
To find:
The minor arcs of the given circle.
Solution:
If any arc of a circle is less than its semicircle, then the arc is called is minor arc.
Since LN and MP are two diameters, therefore they divide the circle is two equal parts. So, the arc LN and arc MP are semicircles.
If arc LN and arc MP are the semicircles, then arc LM, arc MN, arc PL and arc NP are less than the semicircle.
So, arc LM, arc MN, arc PL and arc NP are minor arcs.
Therefore, the correct option is A.
The function y= 15.35 (1.0279)^t represents the value y(in dollars) of a share of stock after t days. Identify the initial amount and determine the growth or decay rate.
9514 1404 393
Answer:
initial amount: $15.35growth: 2.79% per dayStep-by-step explanation:
The coefficient is the initial amount: $15.35.
The growth factor is the base of the exponential term: 1.0279. The growth rate is 1 less than this: 1.0279 -1 = 0.0279 = 2.79%. It is positive, so represents a growth of 2.79% per day.

Answer:
0.7 km per minute , -0.17 km per minute
Step-by-step explanation:
The computation of the average speed is shown below
As we know that
Average speed = Total distance ÷ total time
= (4 + 2 + 1) ÷ (32 + 22 + 16)
= 0.7 km per minute
Now the velocity is
= Change in displacement ÷ change in time
= (4 - 2 - 1) ÷ (32 -22 -16)
= 1 ÷ -6
= - 0.17km per minute

to make F the subject
help
Answer:
F = [tex]\frac{9}{5}[/tex] C + 32
Step-by-step explanation:
Given
C = [tex]\frac{5}{9}[/tex] (F - 32)
Multiply both sides by [tex]\frac{9}{5}[/tex] to clear the fraction
[tex]\frac{9}{5}[/tex] C = F - 32 ( add 32 to both sides )
[tex]\frac{9}{5}[/tex] C + 32 = F

2. Tom bought 30 shares of a company's stock for $19.72/share. He pays a broker a commission of $11 to buy and sell
stock. After one year, Tom sold all his shares, when they were worth $20.75/share.
A. How much did it cost Tom to buy the stock? Show your work.
B. What was Tom's net gain or loss? Show your work
What was Tom's annual rate of return? Show your work and round to tenth
Step-by-step explanation:
a.)Buying: total cost
Total cost= commission + (price per share× Number of of shares ) ;
Total cost= 11 + (19.72×30)= $591.6+11= $601.6
b.)Net gain or loss;
First, find cash received from sale of stock and deduct commission;
Cash from sale =20.75×30= $ 622.5
deduct commission= 622.5-11= $611.5
Gain or loss= sale-cost = 611.5-601.6 = $9.9, meaning there is a profit.
c.) Annual rate of return= (net gain or loss/amount paid)×100%
return= 9.9/(601.6)×100 = 1.645%

Find the length of the third side. If necessary, round to the nearest tenth.
Answer:
18.3
Step-by-step explanation:
a^2 + b^2 = c^2
We can call the unknown side x. The hypotenuse (25) is c.
Knowing this, you know that x^2 + 17^2 = 25^2.
Now simpify!
x^2 + 289 = 625
Subtract 289 from both sides:
x^2 = 338
Now take the square root of 338 which is 18.3 rounded to the nearest tenth.

Answer:
13. Option 3
14.Option 2
Step-by-step explanation:
Option 3 shows that caleb has $5 or less by using the "less than or equal to" sign
Option 2 uses a closed circle to show that $5 is included in the table.
Things to remember that helped me
Closed circle are used for < and > signs to show that the number is being included. They mean "less than or equal to (<)" and "more than or equal to(>)"
Open circles are used for < and > signs. To show that the number is NOT included in the inequality.
Also when looking at the signs < and >, Picture them as arrows. That will show you the direction on the number line they go. For example < is pointing to the left which would mean "LESS THAN" and same with >, its pointing to the right which would mean "MORE THAN"

Find the point-slope equation for
the line that passes through the
points (7, -21) and (-4, 23). Use
the first point in your equation.
y- [?] = [ ](x-[])
Answer:
[tex]y+21 = -4(x-7)[/tex]
Step-by-step explanation:
1) First, find the slope of the line between the two points. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (7, -21) and (-4, 23) into the formula and simplify:
[tex]m = \frac{(23)-(-21)}{(-4)-(7)} \\m = \frac{23+21}{-4-7}\\m = \frac{44}{-11}\\m = -4[/tex]
So, the slope of the line is -4.
2) Now we have all the information we need. To write the equation of the line, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute -4 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of (7, -21) into the equation as well. This gives the following answer:
[tex]y+21 = -4(x-7)[/tex]
