PLEASE HELP The number of bagels sold daily for two bakeries is shown in the table: Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain. 1 Mean for both bakeries because the data is symmetric 2Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric 3 Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric 4 Median for both bakeries because the data is not symmetric
Answer:
4
Step-by-step explanation:
its unclear what the standard for "symmetric" is though both data points have large and small numbers ranging from the 10-40+ thus, the data range is large and the mean will not accurately represent the data well. Thus median would be best

write a system of equations for the problem, and then solve the system. if a plane can travel 340 miles per hour with the wind only 260 miles per hour against the wind, find the speed of the wind and the speed of the plane in still air. please show step by step
Answer:
The speed of plane = 40 m/s
The speed of the wind = 300 m/s
Step-by-step explanation:
Let the speed of the plane = Y
And the speed of the wind = X
If the plane then travel 340 miles per hour with the wind, that means the plane and the wind are moving in the same direction. Therefore,
X + Y = 340 ..... ( 1 )
Also, 260 miles per hour against the wind. That is, the plane is moving opposite to the direction of the wind. Therefore,
X - Y = 260 ..... ( 2 )
Solve the two equations simultaneously by addition. That will eliminate Y
X + Y = 340
X - Y = 260
2X = 600
X = 600/2
X = 300 m/s
Substitutes X in equation (1)
300 + Y = 340
Make Y the subject of formula by collecting the like terms
Y = 340 - 300
Y = 40 m/s
Therefore, the speed of the plane is 40 m/s. While the speed of the wind is 300 m/s.
Using everyday knowledge, indicate whether the if-then statements are correct forward-only or both forward and reverse.
Statement 1: If Bo is Mel's sibling, then Melis Bo's sibling.
Statement 2: If the sprinklers are on, then the grass is wet.
Answer:
1. Both forward and backward
2. Only forward
Step-by-step explanation:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.
Answer:
Using everyday knowledge, indicate whether the if-then statements are correct forward-only or both forward and reverse. Statement 1: If Bo is Mel’s sibling, then Mel is Bo’s sibling. / Statement 2: If the sprinklers are on, then the grass is wet.

Answer:
1). x = 10 m
2). x = 15 cm
3). x = 5 yd
4). AB = 10 units
Step-by-step explanation:
1). By Pythagoras theorem in the given triangle,
a² + b² = c²
Where 'c' = Hypotenuse
a and b = Legs of the right triangle
By substituting measures of the sides in the formula,
x² = 8² + 6²
x = [tex]\sqrt{100}[/tex]
x = 10 m
2). By using Pythagoras theorem in this triangle,
x² = 9² + (12)²
x² = 81 + 144
x = [tex]\sqrt{225}[/tex]
x = 15 cm
3). By Pythagoras theorem,
(13)² = x² + (12)²
169 = x² + 144
169 - 144 = x²
25 = x²
x = 5 yd
4). If BD is a perpendicular bisector of AC,
AD = CD = 6 cm
By Pythagoras theorem in ΔABD,
AB² = BD² + AD²
AB² = 8² + 6²
AB = [tex]\sqrt{100}[/tex]
AB = 10 units
A little shop sells Christmas toys. The wholesale price for each toy in a consignment of 50 toys was $5.5. Half of this quantity was sold before Christmas for the sales price of $15 per piece. two-fifth of the remaining toys have been sold in the next six days for half of the sales price. Finally, the rest of toys have been sold after the New Year for one-third of the sales price. What was the profit the shop made on selling these toys?
Answer:
[tex]Profit = \$250[/tex]
Step-by-step explanation:
Given
Number of Toys = 50
Unit Cost Price = $5.5
Unit Selling price = $15
Required
Determine the profit after sales
First, we need to determine the total cost price;
[tex]Cost\ Price = Number\ of\ toy *\ Unit\ cost\ price[/tex]
[tex]Cost\ Price = 50 * \$5.5[/tex]
[tex]Cost\ Price = \$275[/tex]
First, we need to determine the total sales;
____________________________________________________
Half of the toy was sold at $15;
[tex]Half\ of\ the\ toy = \frac{1}{2} * 50[/tex]
[tex]Half\ of\ the\ toy = 25[/tex]
[tex]Sales = \$15 * 25[/tex]
[tex]Sales = \$375[/tex]
____________________________________________________
Two-fifth of the remaining was sold at half of the sales price
From the above calculation;
[tex]Remaining\ Toy = 50 - 25[/tex]
[tex]Remaining\ Toy = 25[/tex]
Calculating Two-fifth of the remaining:
[tex]\frac{2}{5} * 25[/tex]
[tex]= \frac{50}{5}[/tex]
[tex]= 10[/tex]
Calculating half of the sales price:
[tex]\frac{1}{2} * \$15[/tex]
[tex]\$7.5[/tex]
This means that 10 toys were sold for $7.5
[tex]Sales = 10 * \$7.5[/tex]
[tex]Sales = \$75[/tex]
____________________________________________________
The remaining was sold at one-third of the sales price
From the above calculations (1 & 2);
[tex]Remaining\ Toy = 50 - 25 - 10[/tex]
[tex]Remaining\ Toy = 15[/tex]
Calculating one-third of the sales price:
[tex]\frac{1}{3} * \$15[/tex]
[tex]\$5[/tex]
This means that 15 toys were sold for $5
[tex]Sales = 15 * \$5[/tex]
[tex]Sales = \$75[/tex]
____________________________________________________
Now the total sales can be calculated;
[tex]Total\ Sales = \$375 + \$75 + \$75[/tex]
[tex]Total\ Sales = \$525[/tex]
[tex]Profit = Total\ Sales -\ Cost\ Price[/tex]
[tex]Profit = \$525 -\$275[/tex]
[tex]Profit = \$250[/tex]

What is the true bearing of Milton from Binji?
The leading 0 is important with true bearings. Any true bearing must be three digits.
======================================================
Explanation:
It's not stated, but I'm assuming that Binji and Congo form a flat horizontal line.
B = Binji's location
M = Milton's location
C = Congo's location
The given angles are M = 76 and C = 38. The missing angle is
B = 180-M-C
B = 180-76-38
B = 66
Subtract this from 90 to get 90-66 = 24
The true bearing of Milton from Binji is 024 degrees
In other words, if you are at Binji's location, face directly north, and turn 24 degrees clockwise (turn to the right), then you'll be facing Milton's location.
-------------
Extra info:
In terms of compass notation, the true bearing of 024 degrees converts to N 24 E. This is the same as E 66 N, though convention usually has north used more often (since it's a common reference point with compasses).
N 24 E = start facing north, turn 24 degrees to the east
E 66 N = start facing east, turn 66 degrees to the north

In a newspaper, it was reported that the number of yearly robberies in Springfield in 2013 was 100, and then went up by 25% in 2014. How many robberies were there in Springfield in 2014?
Answer:
125
Step-by-step explanation:
So saying something went up by 25% means that it is essentially
X + .25X
So in this case X = 100 and .25X = 25
So 100 + 25 = 125

Solve for x in the diagram below.
Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
The three angles are complementary to each other.
That means they add up to 90 degrees.
x + 2x + (x + 10) = 90
Combine like terms.
4x + 10 = 90
Subtract 10 on both sides.
4x = 80
Divide both sides by 4.
x = 20

Dylan opened a savings account with $1,250. How much simple interest will he earn if he leaves the money in the account for three years at an interest rate of 0.03? Use the formula i = prt. $112.50 $1,125.00 $37.50 $75.00
Answer:
$112.50
Step-by-step explanation:
So first you will need to understand I=PRT, [tex]I[/tex] stands for the interest on the original investment, P stands for the amount of the original investment, R stands for the interest rate which is supposed to be in decimal form, and T is the time or the number of years you leave the money.
So the equation if you plug in everything would be I= 1,250 times 0.03 times 3. So if you multiply all of the numbers together you would get $112.50. And that is the correct answer

PLEASE HELP THE QUESTION IS BELOW!!
Answer:
The answer is option D.
Their angles measures cannot be equal.
Answer:
D
Step-by-step explanation:
Hello,
What the question requires of us is just the property of complimentary angles and which is
The sum of their angles must be equal to 90°.
When two angles combine together to form angle 90°, it is said to be complimentary and they're referred to as a right angled triangle.
From the option, none of the angles can be up to a right angle triangle (90°)
The sum of their angles can be an acute triangle I.e 45°
45° + 45° = 90°
Knowing the fact that the angles can both be an acute angle (45°), it would be wrong to say both angles cannot be equal.
Hence option D is is wrong and it's the right answer in this case
A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5 m/s2. What is the mass of the bowling ball? Ik the answer is 4.0, but I got it wrong for 4.00. I based the significant numbers off the 22.0 but apparently it's the 5.5. I always get it wrong when the question involves two numbers with different amounts of significant numbers (sometimes I use the smaller one but it wanted the bigger). How do I know when to use more or less significant numbers?
Step-by-step explanation:
You should always use the least number of significant figures. The exception is exact numbers or constants.
For example, there are 60 minutes in an hour. Even though this number has one significant figure, it is an exact number. So 15 minutes converted to hours would be 0.25 hr.
Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality.
8 and 13
Explanation:
Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.
The lower boundary for x is 13-8 = 5. It must be larger than this value.
At the same time, x must be smaller than 13+8 = 21 as well.
So x > 5 and x < 21 becomes 5 < x < 21
In short, x is between 5 and 21. It cannot equal either endpoint.
