Answer:
His median hit = 115
Step-by-step explanation:
Given:
122 45 109 124 and 115 hits
To find his median hit, you will either arrange the hits in ascending order or descending order
In ascending order (lowest to highest value)
45, 109, 115, 122, 124
In descending order (highest to lowest value)
124, 122, 115, 109, 45
It can be observed that thehe hits are 5
The median is the middle value
From either the ascending or descending order arrangement, 115 is the middle hit.

From the top of a 224-ft lighthouse, the angle of depression to a ship in the ocean is 22°. How far is the ship from the base of the lighthouse? Give your answer to the nearest foot.
Answer:
x=554.41 m
Step-by-step explanation:
It is given that,
Height of the lighthouse, OA=224 ft
The angle of depression to a ship in the ocean is 22 degrees.
We need to find the distance between ship and the base of the lighthouse. The figure is attached. We can use trigonometry to find x.
[tex]\tan22=\dfrac{OA}{AB}\\\\\tan22=\dfrac{224}{x}\\\\x=\dfrac{224}{\tan22}\\\\x=554.41\ m[/tex]
So, there is a distance of 554.41 m between the ship and the lighthouse.

Lawrence High prevailed in Saturday's track
meet with the help of 20 individual event
placers earning a combined 68 points. A
first place finish earns 5 points, a second-
place finish earns 3 points, and a third-place
finish earns 1 point. Lawrence had a strong
second-place showing, with as many second
place finishers as first and third-place
finishers combined.
Answer:
The answer is below
Step-by-step explanation:
Let x represent a first place finish, y represent a second place finish and z represent a third place finish.
Since there is a total of 20 individual events, hence:
x + y + z = 20 (1)
A first place finish is 5 point, a second place finish is 3 point and third place finish is 1 point. Therefore:
5x + 3y + z = 68 (2)
The second place finishers is as much as first and third-place finishers combined. Hence:
y = x + z (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = 7, y = 10 and z = 3
This means the number of first place finishes was 7, second place finishes was 10 and third place finishes was 3

Step-by-step explanation:
You actually did really well! It was only in the last two squares that you went wrong. The first wrong one was just the 12 4/9 in the last column and second to last row, which should be 13 7/9. Then with that the last square that is wrong is just the 8 in the 5th column and second to last row, which should be 6 2/3. Those are the only ones so you actually did really well, great job!

Teah was selling candy bars for a fundraiser. She spent $25 on a box of candy bars and sold each candy bar for $2.50. Her profit was $75. Teah wrote the equation 2.5c−25=75 for this situation, and she found c=40. Which statement is true about the solution c=40?
Answer:
The equation is not true. It is actually c=30
Step-by-step explanation:
First you have to divide amount of money she's selling the candy bars for which is $2.50.
If her profit was $75, you want to know how much bars she sold, you will have to divide the amount of money she's selling the candy bars for and the amount she's earning which is $75 divided by $2.50 which is 30.
So c= 30

Three bags of jelly beans contain 26, 28, and 30 beans. The ratios of yellow beans to all beans in each of these bags are $50\%$, $25\%$, and $20\%$, respectively. All three bags of candy are dumped into one bowl. To the nearest percent, what is the percentage of yellow jelly beans in the bowl?
======================================================
Explanation:
The first bag has 26 beans total. Since 50% are yellow, this means 0.50*26 = 13 beans are yellow. Let A = 13.
The second bag has 28 beans, of which 25% are yellow, so 0.25*28 = 7 are yellow. Let B = 7.
The last bag has 30 means and 20% are yellow. So 0.20*30 = 6 are yellow. Let C = 6.
Add A,B,C to get A+B+C = 13+7+6 = 26 yellow from all three bags out of 26+28+30 = 84 beans total.
The percentage of yellow overall is 26/84 = 0.3095 = 30.95% approximately, which rounds to 31%
The Roberts family is taking a road trip. They plan to drive 1500 miles over two days, stopping for the night when they are halfway. How many hours will they drive for the first day if they average 50 mph over the course of the trip?
Explain:
Answer:
Answer:
The number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours
Step-by-step explanation:
The given parameters are;
The distance the Roberts family plan to drive = 1500 miles
The average speed at which they drove = 50 mph
We note that the formula for average speed = Total distance/(time)
Therefore, we have;
50 mph = 1500 miles/(time, t)
Time = 1500 miles/(50 mph) = 30 hours
Given that for the first day of the 2 days, they will cover half their total distance, which is 1500 m/2 = 750 m
The time taken = 750 miles/(50 mph) = 15 hours
The time take to cover half the distance = 15 hours
Therefore, the number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours.

STEP 2 :
Theory - Roots of a product
2.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
2.2 Solve : 3y-2 = 0
Add 2 to both sides of the equation :
3y = 2
Divide both sides of the equation by 3:
y = 2/3 = 0.667
Solving a Single Variable Equation:
2.3 Solve : 7y-1 = 0
Add 1 to both sides of the equation :
7y = 1
Divide both sides of the equation by 7:
y = 1/7 = 0.143

Improper Fraction: [tex]\frac{10}{6}[/tex]
Proper Fraction: [tex]1\frac{4}{6}[/tex]
Simplified Proper Fraction: [tex]1\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{5}{6} + \frac{2}{3}[/tex] Is our equation... first we must find a common denominator! Let's take a look...
6: 1, 6, 12
3: 1, 3, 6
We see that both numbers get to 6 so we use that as our common denominator. Now we plug that in...
[tex]\frac{5*1}{6*1} +\frac{2*2}{3*2}[/tex]
We get...
[tex]\frac{5}{6} +\frac{4}{6} = \frac{10}{6}[/tex]
Now if you want to leave it as an improper fraction your answer will be [tex]\frac{10}{6}[/tex]. However, if you want you answer to be a proper fraction your answer is [tex]1\frac{4}{6}[/tex] which can be simplified further to,[tex]1\frac{2}{3}[/tex].
Whew! What a toughie! We showed that math problem!
I have tried 3 times to solve this.
Step-by-step explanation:
Year 2006- y = 0.09 (6) + 0.04 = 0.58
Year 2008- y = 0.09 (8) + 0.04 = 0.76
Year 2010- y = 0.09 (10) + 0.04 = 0.94
Year 2012- y = 0.09 (12) + 0.04 = 1.12
Year 2014- y = 0.09 (14) + 0.04 = 1.3
"Let x = 6 which is corresponded to 2006", so 8 would correspond to 2008, 10 would correspond to 2010, 12 would correspond to 2012, and 14 would correspond to 14. Plug 6 for x into your equation and do them same for the others.
