Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
Answer:
Justin by 4
Step-by-step explanation:
you add all the numbers for T.J. and for Justin separately and divide by five. you get 42 for Justin and 46 for T.J.

A regular hexagon and a regular octagon are joined as shown on the diagram.
Work out the size of angle x.
The interior angle of a regular hexagon is 120°. As two hexagons share a side, [tex]\( x \)[/tex] equals 120°.
In the given diagram, two regular hexagons share a common side, and an interior angle marked as [tex]\( x \)[/tex] is formed by the sum of the interior angles of the two hexagons. The interior angle of a regular hexagon is [tex]\( \frac{{180^\circ \times (n-2)}}{n} \)[/tex], where [tex]\( n \)[/tex] is the number of sides. For a hexagon [tex](\( n = 6 \))[/tex], this angle is [tex]\( \frac{{180^\circ \times (6-2)}}{6} = 120^\circ \)[/tex].
Considering the interior angles of both hexagons and the angle [tex]\( x \)[/tex], the equation [tex]\( 120^\circ + 120^\circ + x = 360^\circ \)[/tex] arises, as the sum of angles around a point is 360°.

Jackie created a diagonal cross section cut on a sphere. What plane figure did she discover after making the cut?
If you cut a sphere diagonally or along any of its diameters, you will always get a circle as the plane figure because all diameters of a sphere are of equal length.
Explanation:In the field of mathematics, specifically in solid geometry, if Jackie created a diagonal cross section cut on a sphere, the plane figure that she would have discovered is a circle.
The concept behind this is that a sphere is a perfectly symmetrical three-dimensional figure. When we make a cross sectional cut along any diameter of the sphere (which is what Jackie did by making a diagonal cross section), we will always reveal a circular plane figure irrespective of the direction of this cut because all diameters of a sphere are of equal length, thus ensuring the cut is always a circle.

A diagonal cross-section cut on a sphere will reveal a circle.
When Jackie made a diagonal cross-section cut on a sphere, she discovered a circle. Regardless of the angle or position of the cut, the intersection of a plane and a sphere always results in a circular shape. This fundamental geometric property arises from the symmetrical nature of spheres, where every cross-section manifests as a circle.
Thus, Jackie's diagonal cut revealed a circular plane figure, showcasing the inherent relationship between spheres and circles in geometry.
Explain when the median of a data set is a better
measure of center than the mean.
Answer:
The median of a data set is better when you have a term or terms that are not close to the other terms
Step-by-step explanation:
For example:
Say you have the data set
1, 15, 17, 18, 22, 84
The median of these terms would be 17.5
(it is the exact center of the data group)
17 + 18 = 35
35/2 = 17.5
The mean of these terms would be 26.17
(this number is not close to the center because the numbers 1 and 84
are not close enough to the other terms)
1 + 15 + 17 + 18 + 22 + 84 = 157
157/6 = 26.17
Answer:
Sample Response: When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.

Kindly check the attached file for explanation
To represent the number of visitors to the Booneville History Museum t years after 1980, the correct function is D-v(t) = 25000(1.025).
Explanation:To represent the number of visitors to the Booneville History Museum t years after 1980, we can use the formula v(t) = 25000(1 - 0.025)^t. This is because the number of visitors decreases by 2.5% each year. The term (1 - 0.025)^t represents the decay factor where t is the number of years after 1980.
Therefore, the correct function to represent the number of visitors to the Booneville History Museum t years after 1980 is D-v(t) = 25000(1.025).
Find the missing side length in the following triangle.
A 169
B 10
C 1
D 13
The missing side length in the triangle with a hypotenuse of 85 and perpendicular of 84 is 13.
To find the missing side length a in the right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, in this case, we have:
[tex]\[ \text{hypotenuse}^2 = \text{perpendicular}^2 + \text{base}^2 \][/tex]
Given:
- Hypotenuse ( c ) = 85
- Perpendicular ( b ) = 84
- Base ( a ) = ?
Substituting the given values into the Pythagorean theorem equation:
[tex]\[ 85^2 = 84^2 + a^2 \][/tex]
[tex]\[ 7225 = 7056 + a^2 \][/tex]
Now, subtract 7056 from both sides:
[tex]\[ 169 = a^2 \][/tex]
To solve for a, take the square root of both sides:
[tex]\[ a = \sqrt{169} \][/tex]
a = 13
So, the missing side length ( a ) is 13.
Therefore, the correct answer is option D: 13.

Carrie gave her hair stylist a $4.20 tip. The tip was 15% of the cost of the
haircut. What is the total cost of the haircut?
The total cost of her haircut was 28 dollars
step by step:
(percentage) 15 x 6 = 90
4.20 x 6 =25.2
(perscentage) 15 divided by 3 = 5
4.20 divided by 3 = 1.4
1.4 + 1.4 = 2.8
25.2 + 2.8 =28
Final answer:
The total cost of the haircut before adding the tip was $28.00, found by setting up an equation where 15% of the total cost is equal to the $4.20 tip and solving for the total cost.
Explanation:
To calculate the total cost of the haircut that resulted in a $4.20 tip given at the rate of 15%, we need to set up a proportion where 15% of the total cost equals $4.20.
Step 1: Represent the unknown total cost of the haircut by the variable x.
Step 2: Set up the equation representing the tip as 15% of the total cost (0.15x = $4.20).
Step 3: Solve for x by dividing $4.20 by 0.15.
x = $4.20 / 0.15
x = $28.00
Therefore, the total cost of the haircut before adding the tip was $28.00.
write down the expression for the nth term of the following sequence 7,16,25,34,43 the following patterns are made using small squares write down an expression forthe number of small squares in pattern n
Final answer:
The nth term of the sequence 7, 16, 25, 34, 43 is found using the arithmetic sequence formula and is 9n - 2. The number of small squares in pattern n is expressed as n².
Explanation:
The given sequence 7, 16, 25, 34, 43 is an arithmetic sequence, where each term increases by 9. To find the expression for the nth term, we use the formula for the nth term of an arithmetic sequence, which is an = a₁ + (n-1)d, where a1 is the first term and d is the common difference. In this case, a1 = 7 and d = 9, so the nth term expression would be an = 7 + (n-1)9 = 9n - 2.
For the number of small squares in pattern n, if the expression given is n², it suggests the number of squares grows quadratically with the pattern number. Therefore, the expression for the number of small squares in the nth pattern would be n².
