Alonzo describes a histogram as having a cluster from 20–50, a frequency of 0 from 10–20, and a peak at 40–50. Which histogram is he describing?
Answer:
Skewed Left
Step-by-step explanation:
First we will try to draw the histogram in order to interpret its type.
Its given that from 10-20 the frequency is 0
and 20-50 there are clusters in the histogram but the peak is there at 40-50
So by visualizing the histogram which is hereby attached depicts that the histogram is skewed left as skewed histogram is one in which the frequency starts from 0 and the highest frequency occurs at the end so as is in the given problem.

In the triangle below which of the following is equivalent to the tangent of 52 degrees?
Answer:
Option D. [tex]\frac{24}{7}[/tex].
Step-by-step explanation:
In any right angle triangle tangent of an angle is the ratio of opposite side and adjacent side.
tan x =[tex]\frac{\text{Opposite side (24)}}{\text{Adjacent side (7)}}[/tex]
= [tex]\frac{24}{7}[/tex]
therefore, Option D. [tex]\frac{24}{7}[/tex] is the answer.
Write a number in which the value of the 3 is 10 times the value of the digit 3 in 156.32
Answer:
1563.2
Step-by-step explanation:
If you just multiply 0.3 by 10 you will get 3
Now all you need to do is write 3 or have a number which has unit place value of 3
Answer: The number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3
Step-by-step explanation:
The given number = 156.32
The place value of 3 in 156.32 is 3 tenth [since it the left most number after the decimal].
3 tenth can be written as [tex]\frac{3}{10}[/tex]
The number 10 times [tex]\frac{3}{10}[/tex]= [tex]10\times\frac{3}{10}[/tex]
Therefore, The number 10 times [tex]\frac{3}{10}[/tex]=3
Hence, the number in which the value of the 3 is 10 times the value of the digit 3 in 156.32 = 3

Alicia uses 3/4 gallon of paint to paint her room. Becca uses for 4/5 gallon more than Alicia to paint her room. How many gallons of paint do they use together
Answer:
23/10 gallons
Step-by-step explanation:
Alicia uses 3/4 gallon of paint to paint her room.
Alicia use = 3/4 gallon of paint
Becca uses for 4/5 gallon more than Alicia to paint her room.
Becca uses = Alicia (3/4 gallons ) + 4/5
Becca uses = [tex]\frac{3}{4} + \frac{4}{5}[/tex]
Total paint used together = Aliccia used + Becca used
[tex]\frac{3}{4}+\frac{3}{4} + \frac{4}{5}[/tex]
Add like fractions 3/4 + 3/4 becomes 6/4
[tex]\frac{6}{4} + \frac{4}{5}[/tex]
Make the denominators same
[tex]\frac{6*5}{4*5} + \frac{4*4}{5*4}[/tex]
[tex]\frac{30}{20} + \frac{16}{20}[/tex]
[tex]\frac{46}{20}[/tex]
Divide top and bottom by 2

Man can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?
Answer:
one box of crackers costs $0.70
Step-by-step explanation:
Let $x be the price of 1 container of yogurt and $y be the price of 1 box of crackers.
1. Man can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. 4 containers of yogurt cost $4x and 3 boxes of crackers cost $3y. In total,
[tex]3x+4y=9.55.[/tex]
2. Man can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. 2 containers of yogurt cost $2x and 2 boxes of crackers cost $2y. In total,
[tex]2x+2y=5.90.[/tex]
3. Solve the system of two equations:
[tex]\left\{\begin{array}{l}3x+4y=9.55\\2x+2y=5.90\end{array}\right.[/tex]
Multiply the second equation by 2 and subtract it from the first equation:
[tex]3x+4y-2(2x+2y)=9.55-5.90\cdot 2,\\ \\3x+4y-4x-4y=9.55-11.80,\\ \\-x=-2.25,\\ \\x=\$2.25.[/tex]
Then
[tex]2\cdot 2.25+2y=5.90,\\ \\2y=5.90-4.50,\\ \\2y=1.40,\\ \\y=\$0.70[/tex]
By setting up a system of equations and using elimination, we find that one box of crackers costs $2.25.
To solve the cost of one box of crackers, we need to set up two equations based on the information given:
4y + 3c = $9.552y + 2c = $5.90We use 'y' to represent the cost of one container of yogurt and 'c' for the cost of one box of crackers. To find the value of 'c', we can use substitution or elimination.
Let's eliminate 'y' by multiplying the second equation by 2, which gives us 4y + 4c = $11.80. Subtracting the first equation from this, we get:
c = $11.80 - $9.55
c = $2.25
So, one box of crackers costs $2.25.

Step-by-step explanation:
After changing its format, a radio station lost 34% of its listeners. If there were an estimated 83,000 listeners orginally, how many listeners does the radio station have now?
Final answer:
The radio station has 54,780 listeners now.
Explanation:
To find the number of listeners the radio station has now, we need to calculate the number of listeners it lost after changing its format. If the station lost 34% of its listeners, we can calculate the number of lost listeners by multiplying the original number of listeners by 0.34 (34%).
Lost Listeners = 83,000 * 0.34 = 28,220 listeners
To find the number of listeners the radio station has now, we subtract the lost listeners from the original number of listeners.
Number of Listeners Now = 83,000 - 28,220 = 54,780 listeners
Solve. 2/3x = -20. A) -60 B) -30 C) -10 D) 10
Simplify 2/3x to 2x/3
2x/3 = -20
Multiply both sides by 3
2x = -20 × 3
Simplify 20 × 3 to 60
2x = -60
Divide both sides by 2
x = -60/2
Simplify 60/2 to 30
x = -30
Answer: B) -30
Answer:
the answer to you question is -30
Step-by-step explanation:
what you have to do is take the fraction and multiply it by its reciprocal to get it away from the x and if you multiply on one side then you have to multiply on the other side also so you would multiply -20 by 3/2 the you would get the answer of -30

Which system of inequalities is shown in the graph?
The system of the inequalities is y ≥ 2x - 2, y ≥ x - 3x. Option B
How to determine the inequalitiesTo determine a system of inequalities graphically, plot each inequality on the same coordinate plane.
Represent each inequality as a boundary line (dashed or solid, depending on the inequality sign) and shade the region that satisfies the inequality. The solution area is the overlapping shaded region where all inequalities intersect.
The points within this shared region satisfy all the given inequalities simultaneously. If there is no intersection or common shaded area, the system has no solution that satisfies all the inequalities simultaneously.
So, we have that;
y ≥ 2x - 2
y ≥ x - 3x

-5(3x^2+5x+b)=ax^2-25x+45
Answer:
a = - 15 and b = - 9
Step-by-step explanation:
distribute the left side
- 15x² - 25x - 5b
For - 15x² - 25x - 5b = ax² - 25x + 45
Then the coefficients of like terms must be equal, hence
comparing coefficients of x² term ⇒ a = - 15
comparing constant term ⇒ - 5b = 45 ⇒ b = - 9
Answer: a = -15, b = -9
Step-by-step explanation:
-5(3x² + 5x + b) = ax² - 25x + 45
-15x² - 25x - 5b = ax² - 25x + 45 distributed -5 on left side
Notice that the middle terms (-25x) are equal, so the the remaining terms will also be equal.
-15x² = ax² ⇒ -15 = a
-5b = 45 ⇒ b = -9
the perimeter is at least 18 feet. Write and solve inequality that represents x
The inequality that represents x is [tex]$x \geq 6$[/tex]. This means that the total length of all the sides of the shape must be at least 6 feet.
Let's say the total length of all the sides of the shape is represented by the variable x. We are given that the perimeter is at least 18 feet. This can be written as an inequality: [tex]$x \geq 18$[/tex]
Since the sides of the triangle measure 3 feet, 5 feet and x-2 feet, we can express the perimeter inequality in terms of x as: [tex]$x+ 3 + 5 +x-2 \geq 18$[/tex]
Simplifying the left side of the inequality, we get: [tex]$2x + 6 \geq 18$[/tex]
Subtracting 6 from both sides, we obtain: [tex]$2x \geq 12$[/tex]
Dividing both sides by 2, we get: [tex]x \geq 6$.[/tex]

What is the answer ?
Answer:
2y
Step-by-step explanation:
Simplifying
21x + -42y = 0
Solving
21x + -42y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '42y' to each side of the equation.
21x + -42y + 42y = 0 + 42y
Combine like terms: -42y + 42y = 0
21x + 0 = 0 + 42y
21x = 0 + 42y
Remove the zero:
21x = 42y
Divide each side by '21'.
x = 2y
Simplifying
x = 2y

What’s 22.5 as a fraction in simplest form
Answer:
22.5% = 9/40 as a fraction
Step by Step Solution
To convert 22.5 percent to a fraction follow these steps:
Step 1: Write down the percent divided by 100 like this:
22.5% = 22.5/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,
22.5/100 = (22.5 x 10)/(100 x 10) = 225/1000.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25. So,
(225÷25)/(1000÷25) = 9/40 when reduced to the simplest form.
