x = 6
Step-by-step explanation:
Step 1: Group all y terms on the left side of the equation
Subtract 3x from both sides:
5x - 7 = 3x + 5
5x - 7 -3x = 3x + 5 - 3x
2x - 7 = 3x + 5 - 3x
2x - 7 = 5
Step 2: Group all constants on the right side of the equation
Add 7 to both sides of the equation:
2x - 7 = 5
2x - 7 + 7 = 5 + 7
2x = 5 + 7
2x = 7
Step 3: Isolate the y
Divide both sides of the equation by 2:
2x = 12
2x/2 = 12/6
x = 12/2
x = 6
The solution of the given expression is x = 6.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Subtract 3x from both sides:
5x - 7 = 3x + 5
5x - 7 -3x = 3x + 5 - 3x
2x - 7 = 3x + 5 - 3x
2x - 7 = 5
Add 7 to both sides of the equation:
2x - 7 = 5
2x - 7 + 7 = 5 + 7
2x = 5 + 7
2x = 7
Divide both sides of the equation by 2:
2x = 12
2x/2 = 12/6
x = 12/2
x = 6

A comedy club hosts an amateur comedy night, a good opportunity for aspiring comedians to
perform. Of the 8 amateur comedians who signed up for tonight's show, 6 perform satirical
comedy,
If the host randomly selects 4 comedians from the sign-up list, what is the probability that all
of them practice satirical?
Write your answer as a decimal rounded to four decimal places.
Answer:
0.2143 probability that all of them practice satirical.
Step-by-step explanation:
The comedians are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
8 comedians means that [tex]N = 8[/tex]
6 practice satirical means that [tex]k = 6[/tex]
Sample of 4 means that [tex]n = 4[/tex]
What is the probability that all of them practice satirical?
This is P(X = 4). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 4) = h(4,8,4,6) = \frac{C_{6,4}*C_{2,0}}{C_{8,4}} = 0.2143[/tex]
0.2143 probability that all of them practice satirical.

8. When nominal GDP is $900 and the price index is 150, real GDP would equal
$60
$135
$600
$1,350
$6,000
Answer:
$600
Step-by-step explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
Nominal GDP is GDP calculated using current year prices while Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.
Price index measures how prices change over a period of time. It is a measure of inflation
Real GDP = (nominal / price index) x 100
($900 / 150) X 100 = $600

A student had 10 marks in mathematics. But he remembers only 7 of them:
1,1,2,2,3,4,5. The mode of the marks is 3 and the mean is 2.9. What are the
missing marks? Once you manage to find these marks, create a frequency
table for the students' scores and visualize the results with a bar chart.
Answer:
The missing marks are 3, 3, and 5.
Step-by-step explanation:
Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.
