Interpreting Algebraic Expressions
11+9k=6n
The expressions has 2 terms.
True or false?
The statement is false as the number of terms in the equation is not two
How to determine the number of terms?The equation is given as
11 + 9k = 6n
Consider an equation represented as
a + b = c
The variables a, b and c are the terms of the equation
This means that the equation 11 + 9k = 6n has the following terms
11, 9k and 6n
The number of these terms is 3
So, the equation has three terms
Hence, it is false that the equation has two terms

Find the greatest common factor of these two expressions:
30x^8 w^4 v^3 and 12w^7 v^5
Answer:
[tex]Factor = 6w^4 v^3[/tex]
Step-by-step explanation:
Given
[tex]30x^8 w^4 v^3[/tex] and [tex]12w^7 v^5[/tex]
Required
Determine the common factor.
To do this, we simply factorize each. SO, we have:
[tex](1)\ 30x^8 w^4 v^3=: 2 * 3 * 5 * x^8 * w^4 * v^3[/tex]
[tex](2)\ 12w^7 v^5:=\ 2 * 2 * 3 * w^4*w^3 * v^3 * v^2[/tex]
Check for similar factors.
[tex]Factor = 2 *3 * w^4 * v^3[/tex]
[tex]Factor = 6w^4 v^3[/tex]
The above represents the similar factor

Find the length of the chord made by 3x2 - y2 = 3 and y + x – 5 = 0.
Answer:
The correct answer is "9√2 units".
Step-by-step explanation:
The given equations are:
⇒ [tex]3x^2-y^2=3[/tex]...(equation 1)
⇒ [tex]y+x-5=0[/tex]...(equation 2)
According to the 2nd equation, we get
⇒ [tex]y+x-5=0[/tex]
⇒ [tex]y=5-x[/tex]
On substituting the value of "y" in the 1st equation, we get
⇒ [tex]3x^2-y^2=3[/tex]
[tex]3x^2-(5-x)^2=3[/tex]
[tex]3x^2-(25+x^2-10x)=3[/tex]
[tex]2x^2+10x-28=0[/tex]
On taking common, we get
[tex]x^2+5x-14=0[/tex]
On applying factorization, we get
[tex]x^2+7x-2x-14=0[/tex]
[tex]x(x+7)-2(x+7)=0[/tex]
[tex](x+7)(x-2)=0[/tex]
[tex]x+7=0[/tex]
[tex]x=-7[/tex]
or,
[tex]x-2=0[/tex]
[tex]x=2[/tex]
Now,
The points are:
(-7, 12) = (x₁, y₁)
(2, 3) = (x₂, y₂)
By using the distance formula, the length of chord will be:
= [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
On substituting the values in the above formula, we get
= [tex]\sqrt{(2-(-7))^2+(3-12)^2}[/tex]
= [tex]\sqrt{(9)^2+(-9)^2}[/tex]
= [tex]\sqrt{81+81}[/tex]
= [tex]9 \sqrt{2}[/tex] units

Solve: 7.2h = 57.6 A. h= 0.8 B. h = 8 C. h = 50.4 D. h = 80
Answer:
B. h=8
Step-by-step explanation:
The answer is B. h=8. I know because I solved to get h by itself. First, I set up the problem.
7.2h=57.6
Then, I divided each side by 7.2, so I could get h by itself.
h=8
You can check to make sure this is correct by plugging in the value we got for h into the equation.
7.2(8)=57.6
In conclusion, the answer is B. h=8

Answer:
X= ( 18/5 , 0)
Y= (0,-2)
Step-by-step explanation:
substitute 0 for y and solve for x
-5x+9(0) = -18
-5X + 0 = -18
-5X= - 18 - 0
-5X = -18
X = - 18/-5
X = 18/5
solve for Y
-5(0) +9y = -18
= 9y = -18
y= -2
What is the volume, in cubic feet of the tent.
Answer:
96ft³
Step-by-step explanation:
Okay, so the formula for finding the volume of a triangular prism is base x height, so we first have to find the base:
6 x 4 ÷ 2 = 12
So then we plug our numbers into the formula:
12 x 8 = 96
So, the volume of the tent is 96ft³

Answer:
The answer is "4.8, 3.84, and 1.96".
Step-by-step explanation:
Given:
[tex]\to p = 0.2\\\\\to q = 1 - p = 1 - 0.2 = 0.8\\\\\to n = 24\\\\[/tex]
By using the binomial distribution:
[tex]\to Mean(\mu) = n \times p = 24 \times 0.2 = 4.8\\\\\to variance (\sigma^2) = n \times p \times q = 24 \times 0.2 \times 0.8 = 3.84\\\\\to Standard \ deviation (\sigma) = \sqrt{n \times p \times q} = \sqrt{24 \times 0.2 \times 0.8} = 1.96[/tex]

Step-by-step explanation:
A political pollster wants to know what proportion of voters are planning to vote for the incumbent candidate in
an upcoming election. A poll of 150 randomly selected voters is taken from the more than 2,000 voters in the
population, and 78 of those selected plan to vote for the incumbent candidate.
Based on this sample, which of the following is a 90% confidence interval for the proportion of all voters who
plan to vote for the incumbent candidate?
Answer:
90% confidence interval -> {0.4529, 0.5871}
Step-by-step explanation:
Check conditions for a 1-proportion z-interval:
np>10 -> 150(0.52)>10 -> 78>10 √
n(1-p)>10 -> 150(1-0.52)>10 -> 72>10 √
Random sample √
n>30 √
For a 90% confidence interval, the critical value is z=1.645
The formula for a confidence interval is:
CI = p ± z√[p(1-p)/n]
Given:
p = 78/150 = 0.52
n = 150
z = 1.645
Therefore, the 90% confidence interval is:
CI = 0.52 ± 1.645√[0.52(1-0.52)/150] = {0.4529, 0.5871}
Context: We are 90% confident that the true proportion of all voters who
plan to vote for the incumbent candidate is contained within the interval
