11 students in the Environmental club represent 4% of the students in the seventh grade. How many students are in the seventh grade?
Answer:
275
Step-by-step explanation:
The best way to do this is to set it up in this equation:
4/100 = 11/x, in this, the 4 over 100 represents 4% out of 100%. The 11 over x represents the 11 students out of x amount of students. With this equation, you cross multiply to get 4x = 1100. Then you divide both sides by 4 to get x by itself. This will give you x=275
After solving the equation, the total number of students in the 7th grade is 275.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data mentioned in the question,
Total number of students in the Environmental club = 11
Percentage of students from 7th grade = 4%
Let the total number of students in 7th grade be x
Then, the equation according to the statement will be,
4% of x = 11
So,
x = (11 × 100)/4
x = 275

1) The probability that an individual is left-handed is 12%. In a randomly selected class of 30 students, what is the probability of finding exactly 4 left-handed students?
2) Sixty-five percent of men consider themselves knowledgeable football fans. If 10 men are randomly selected, find the probability that exactly six of them will consider themselves knowledgeable fans.
Answer:
0.2047
0.2377
Step-by-step explanation:
1.
What we have here is a binomial distribution
Probability p = 0.12
N = number of students in the class = 30
Probability of finding 4 left handers
P(x = 4) = 30C4 x (0.12)⁴ x (0.88)²⁶
= 27405 x 0.00020736 x 0.03602047835
= 0.2047
2.
This is also a binomial distribution
N = 10 p = 0.65
P(of 6 knowledgeable fans)
= 10C6 x (0.65)⁶ x (0.35)⁴
= 210 x 0.0754189 x 0.01500625
= 0.2377
Noah would like to cover a rectangular tray with rectangular tiles. The tray has a width of 11 1/4 inches and an area of 50 5/8 square inches. Find the length of the tray in inches.
Answer:
67 sq ft
Step-by-step explanation:
The length of the rectangle with an area of 405/8 square inches and a width of 45/4 inches is 9/2 inches.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle = length×width.
Given, The tray has a width of 45/4 inches and an area of 405/8 square inches.
∴ If area = length×width.
Then, length = area/width.
length = (405/8)/(45/4) inches.
length = (405/8)×(4/45) inches.
length = 9/2 inches.

What is the equation of the line –3x–2y=30 in slope-intercept form?
Enter your answer in the box.
Answer:
y = - 1.5x - 15
Step-by-step explanation:
Step 1:
- 3x - 2y = 30 Equation
Step 2:
- 2y = 3x + 30 Add 3x on both sides
Step 3:
y = - 1.5x - 15 Divide 2 on both sides
Answer:
y = - 1.5x - 15
Hope This Helps :)
Answer: y = - 1.5x - 15
Step-by-step explanation:
First, we will add 3x to both sides of the equation.
-2y = 3x + 30
Next, we will divide 2 on both sides of the equation.
y = -1.5x - 15
Answer - y = -1.5x - 15

Answer: 29
Step-by-step explanation: 180-146= 34-5 29.
Answer:
[A] 29
Explanation:
Equation: 180 = 146 + (x + 5)
The line adds up to 180, so we need to find what x is180 = 146 + (x + 5)
Switch Sides
146 + (x + 5) = 180
Remove Parenthesis
146 + x + 5 = 180
Group Like Terms
x + 146 + 5 = 180
Add: 146 + 5 = 151
x + 151 = 180
Subtract 151 From Each Side Of Equation
x + 151 - 151 = 180 - 151
x = 29

Answer:
x = 26
2x = 52
(5x - 2) = 128°
Step-by-step explanation:
✔️According to the exterior angle theorem of a ∆, thus:
(5x - 2)° = 2x° + 76°
Solve for x
5x - 2 = 2x + 76
Collect like terms
5x - 2x = 2 + 76
3x = 78
Divide both sides by 3
x = 26
✔️2x
Plug in the value of x
2(26) = 52°
✔️5x - 2
Plug in the value of x
5x - 2 = 5(26) - 2
= 128°

Predict the violent crime rate for a Southern state with an urbanization of 55.4 and a poverty rate of 13.7.
Answer:
The violent crime rate for this Southern state with an urbanization of 55.4 and a poverty rate of 13.7 is predicted to be:
7.6%.
Step-by-step explanation:
a) Data and Calculations:
Urbanization rate = 55.4%
Poverty rate = 13.7%
The predicted violent crime rate = urbanization rate * poverty rate
= 55.4% * 13.7%
= 7.5898%
= 7.6%
b) The prediction of violent crime rate follows some established researches that show that crime rates are higher in urban than rural areas. There is also a dynamic link between poverty, unemployment, and crime rate. Unemployment is usually high in more urbanized areas. As a result, unemployment increases poverty, and poverty reinforces the commission of crimes.

Write an equation of the line that passes through (1, -8) and is parallel to the line y = -3x - 7
Answer:
the desired new equation is y = -3x - 5
Step-by-step explanation:
The desired equation of this new (parallel) line has exactly the same form as the given line y = -3x - 7. Only the y-intercept will be different.
Starting with y = -3x - 7, replace x with the x-coordinate of the given point (1, -8) and y with the y-coordinate. We get:
-8 = -3(1) + C, where C is the new y-intercept and is to be determined.
Then C = -5, and the desired new equation is y = -3x - 5.

Solve the following system of equations using a method of your choice.
Write the solution as an ordered pair ( , ) and then you will be prompted to explain your thinking.
4x-2y=4
x+y=10
Answer:
Step-by-step explanation:
cant remember what this method is called but
change the second equation to be y = something
x + y = 10
y = -x + 10
plug in this y= in the first equation to get x
4x -2(-x + 10) = 4
4x + 2x -20 = 4
6x = 24
x = 4
then plug in the x we found into the original second equation
4 + y = 10
y = 6
so your ordered pair would be (4,6)

Which counterexample shows the conjecture “If the product of two numbers is positive, then the two numbers must both be positive” to be false?
(-3)(-1) = (+3)
(-3)(+1) = (-3)
(+3)(+1) = (+3)
(+3)(-1) = (-3)
Answer:
(-3)(-1) = (+3)
Step-by-step explanation:
In this question, we have to find the equation that proves the statement wrong.
The statement says that “If the product of two numbers is positive, then the two numbers must both be positive"
We can already make this statement false because both numbers doesn't only have to be positive in order to have the product of a positive number.
We know that if you multiply two negatives, the number turns positive.
Therefore, we can see that displayed in this equation: (-3)(-1) = (+3)
This is because (-3)(-1) = 3, and they both aren't positive numbers.
Answer:
(-3)(-1) = (+3)
Step-by-step explanation:
The counterexample would be that the product of two negative numbers is positive but the numbers are negative. For example, (-3)(-1) = (+3).
