The measure of central tendency of a distribution of data that can take multiple value is the mode
How to determine the measure of central tendency?In a given dataset;
The range is the difference between the least and the highest data elementThe mean is the average valueThe median is the middle valueAll the above measures can take only one value in a dataset
However, the mode can take multiple values, because it represents the data element with the highest frequency (and multiple data elements can have the same frequency)

Gus bought 12 gallons of gas at $2.17
a gallon, a bottle of oil for $2.49 and
two jugs of anti-freeze for $7.98 each.
He paid $1.52 in tax for the oil and
anti-freeze. If he paid with a $50 bill,
how much change did he receive?
bro help lol
Answer:
$3.99
Step-by-step explanation:
a gallon of gas=2.17$
12 gallons of gas=2.17$×12 =26.04$
2 jugs of anti freeze =7.98$ × 2 = 15.96$
a bottle of oil = 2.49$
tax= 1.52$
total= 46.01$
he paid 50$
so the change could be 50$-46.01$ = 3.99$
the answer is 3.99$

Find the slope and the equation for the line passing through the points: (-3,0) and (-1,2)
Answer:
slope: 1equation: y = x +3Step-by-step explanation:
The slope of the line between two points can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (2 -0)/(-1 -(-3)) = 2/2
m = 1 . . . . . the slope of the line is 1

The value of the y-intercept can be found by solving the slope-intercept equation for b.
y = mx +b
b = y -mx

Identify the equation for the parabola with the focus F(0,-9.5) and directrix y =9.5
Considering the given focus and directrix, the equation of the parabola is given by:
[tex]y = -2.375x^2[/tex]
What is the equation of a parabola?The equation of a parabola, with a directrix in y, is:
[tex]y - k = a(x - h)^2[/tex]
In which:
The value of a is of 0.25C.The vertex is (h,k).The focus if (h, k+C).The directrix if y = k - C.In this problem, we have that the x-coordinate of the vertex is h = 0.
From the focus and the directrix, we have that:
k+C = -9.5
k - c = 9.5.
Hence k = 0, C = -9.5 = a = 0.25C = -2.375.

Cooper gave out a survey to some students in his school about their favorite color.
tudents could choose between red and blue. 129 of those surveyed said their favorite
color was red. 57% of the students surveyed said their favorite color was blue. How
many students were surveyed in total?
Answer:
300 students were surveyed.
Step-by-step explanation:
Well, we know that 57% of students like blue, so that leaves 43% who like red. By simply dividing 129 by 43, we get 3, so know we can conclude that 1% is equal to 3 students. Knowing this, we can multiply 3 by 57 to get 171. Adding these up, we get 300, and we can verify this, by simply finding the difference between 57 and 43, which is 14. Now that we also know that 1% is equal to 3 students, we can multiply 14 by 3, to get 42, which is also the difference between 171 and 129.

2 (y-value increase as x-value also increase)
Step-by-step explanation:
Lets look at the graph! when x is 7, y is 4. and when x is 9, y is 5 which is proving that they BOTH increase
solve x/9 + 1/3 = -4/3
The solution is x = ?
Answer:
x = - 15
Step-by-step explanation:
[tex]\frac{x}{9}[/tex] + [tex]\frac{1}{3}[/tex] = - [tex]\frac{4}{3}[/tex] ( multiply through by 9 to clear the fractions )
x + 3 = - 12 ( subtract 3 from both sides )
x = - 15
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.

Suppose a laboratory has a 30 g sample of polonium-210. The half-life of polonium-210 is about 138 days. a. How many half-lives of polonium-210 occur in 1104 days? b. How much polonium is in the sample 1104 days later?
9; 0.06 g
8; 0.12 g
8; 2,070 g
8; 3.75 g
Step-by-step explanation:
the decay or "half-life" of radioactive particles is really a big joke by nature, in my opinion.
it takes that much time for half of the amount to decay, so, naturally, one wound assume that after a second interval then the other half is gone.
but far from it. no, only the half of the originally remaining half is then gone (the half of a half is 1/2 × 1/2 = 1/4). and after another interval the half of the half of the half is then gone. and so on.
so, this creates a geometric sequence with the common factor (or ratio) if 1/2.
that means every term is created by multiplying the previous term by 1/2.
a.
how many "half-lives" in 1104 days ?
well, with every 138 days such a half-life is over.
so, the answer is how often 138 fits into 1104 :
1104 / 138 = 8
there are 8 "half-lives" of polonium-210 in 1104 days.
b.
how much polonium-210 is in the sample after 1104 days ?
since we have 8 half-lives, we need to multiply the original amount 8 times by 1/2. in other words by 1/2⁸.
2⁸ = 256
so, our calculation is
30 g × 1/256 = 0.1171875 g ≈ 0.12 g
so, the second answer option is correct.

I NEED HELP!! PLEASE HELP!! Find the area of the shaded region. Round your answer to the nearest hundredth.
area: about __ft2
The area of the shaded region in the given quadrant, to the nearest hundredth is: 4.57 ft².
What is the Area of a Quadrant?Area of a quadrant = 1/4 × area of a circle = 1/4 × πr²
The figure has been partitioned into A, B, C to E.
The area of the shaded region = A + B
Step 1: Find the area of A:
Area of A = area of the square formed by D, A, and C - area of D + area of C.
Area of D = area of square - area of quadrant formed by A and C
Area of D = s² - 1/4 × πr² = 2² - 1/4 × π(2)²
Area of D = 0.86 ft²
Area D = area of C = 0.86 ft²
Area of D + area of C = 2(0.86) = 1.72 ft²
Area of A = 4 - 1.72 = 2.28 ft²
Step 2: Find the area of quadrants E and F
Area of quadrants E and F = 2(1/4 × πr²) = 2(1/4 × (3.14)(2)²)
Area of quadrants E and F = 6.28 ft².
Step 3: Find the area of B
Area of B = area of the biggest quadrant - area of quadrants E and F + area of square formed by D, A, and C
Area of B = 1/4 × πr² - 6.28 + 4
Area of B = 1/4 × π(4²) - 10.28
Area of B = 2.29 ft².
Step 4: Find the area of the shaded region
Area of the shaded region = A + B = 2.28 + 2.29
Area of the shaded region = 4.57 ft².
In conclusion, the area of the shaded region in the given quadrant, to the nearest hundredth is: 4.57 ft².

In an isosceles triangle, one angle is 81° greater than each of the other two equal angles. Find the measure of all three angles.
The two smaller angles are each
The larger angle is °.
The measure of all three angles is 81, 49.5 and 49.5 degrees.
What is Angle sum property?According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees. A triangle is a closed figure formed by three line segments, consisting of interior as well as exterior angles.
The angle sum property formula for any polygon is expressed as, S = (n − 2) × 180°, where 'n' represents the number of sides in the polygon. This property of a polygon states that the sum of the interior angles in a polygon can be found with the help of the number of triangles that can be formed inside it.
Given:
The triangle is isosceles which has two sides equal.
Also Two angles equals.
Let the equal angles are x.
third angle= 81 degree
Now, Using Angle Sum property
x+ +x + 81 = 180
2x= 180-81
2x= 99
x= 99/2
x= 49.5 degrees
Hence, the two smaller angles are 49.5 degrees.

Answer:
60°, 115°, 65°Step-by-step explanation:
Angles a and 60°, also c and 65° are alternate interior angles and therefore are equal:
a = 60°c = 65°Angles b and 65° form a linear pair, so they sum to 180°
b + 65° = 180°b = 180° - 65°b = 115°Answer:
a = 60°
b = 115°
c = 65°
Step-by-step explanation:
Alternate Interior Angles Theorem
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent (same).
Therefore, a = 60° and c = 65°
Angles on a straight line sum to 180°
⇒ b + 65° = 180°
Subtracting 65° from both sides:
⇒ b + 65° - 65° = 180° - 65°
⇒ b = 115°
