Which of the following options have the same value as 30\%30%30, percent of 818181?
Answers
Answer:
Option B is correct = \(0.3 \times 81\)
Step-by-step explanation:
The complete question is: Which of the following options have the same value as 30% of 81?
Group of choices is:
(A) \(\frac{30}{100}\times 81 \times 100\)
(B) \(0.3 \times 81\)
(C) \(0.03 \times 81\)
(D) \(\frac{3}{10}\times 81 \times 10\)
(E) \(30 \times 81\)
Now, the expression given to us is 30% of 81.
Simplifying the above expression we get;
30% of 81 = \(\frac{30}{100} \times 81\)
= \(\frac{3}{10} \times 81\) = \(0.3 \times 81\)
Now, we will solve each of the given options and then see which option matches with our calculation.
Option (A) is given;
\(\frac{30}{100}\times 81 \times 100\) = \(30 \times 81\)
This doesn't match with our answer, so this option is not correct.
Option (B) is given;
\(0.3 \times 81\)
This matches with our answer, so this option is correct.
Option (C) is given;
\(0.03 \times 81\)
This doesn't match with our answer, so this option is not correct.
Option (D) is given;
\(\frac{3}{10}\times 81 \times 10\) = \(3 \times 81\)
This doesn't match with our answer, so this option is not correct.
Option (E) is given;
\(30 \times 81\)
This doesn't match with our answer, so this option is not correct.

D) subtract 4 times the second equation from 3 times the first equation
PLEASE HELP!!!
Answers
Answer:
Option B is correct.
add 4 times the second equation to 3 times the first equation
Step-by-step explanation:
Answer:
B) add 4 times the second equation to 3 times the first equation
Step-by-step explanation:
So you have these two equations:
2x - 4y = 6
-3x + 3y = 12
In order "to solve this system of equations by elimination" we want to make BOTH of the equations have a term (in this case the y term) and have the same coefficient (that's the number right next to the y) If they are the exactly same number, even the same sign in front, then we would subtract the equations. If they have the same coefficient but different signs, then we would add the equations. This will eliminate the y term completely. So in order to make them have the same coefficient. We'll multiply the first equation by 3 and the second equation by 4
3(2x - 4y = 6)
4(-3x + 3y = 12) multiplying all the way across the equation (distributing)
We'll get
6x -12y = 18
-12x + 12y = 48 Then you are actually adding from the top, down and get one equation from adding the two existing ones together.
-6x = 66 And then you are able to solve it by dividing both sides by -6 to get
x = -11
You can then use either equation and x = -11 to find y. Your solution is the x, y pair. You can check it by putting the x and y into both equations and finding it makes a true statement in both.

What are linear equations in two variables?
Therefore, a linear equation in two variables is any equation that can be written in the form ax + by + c = 0, where a, b, and c are real values, and a and b are not equal to zero.
Given two linear equations of two variables.
y = -4x .....eq 1
6x - y = 30 .....eq 2
We have to solve them using substitution.
Now,
by substituting eq 1 in eq 2,
6x -(-4x) = 30
6x + 4x = 30
10x = 30
x = 3
from eq 1,
y = -4x = -4*3 = -12
Therefore, x = 3 and y = -12

So, we know that JI and JX are perpendicular (first statement). That just means that they mean at an angle of 90*.
That means CIJ has an angle of 150*-90*=60*. Therefore, as IG bisects CIJ , both CIG and GIJ have angle 60*/2=30*.
Half a circle has 180*. GIR is just short of CIG to be a half circle.
Therefore
180*-mCIG=mGIR
We know mCIG was 30*, so

A company prices its tornado insurance using the following assumptions:
• In any calendar year, there can be at most one tornado.
• In any calendar year, the probability of a tornado is 0.11.
• The number of tornadoes in any calendar year is independent of the number of tornados in any other calendar year.
Required:
Using the company's assumptions, calculate the probability that there are fewer than 3 tornadoes in a 14-year period.
Answers
Answer:
The probability is \(P(X < 3) = P(X \le 3-1 = 2 ) = 0.8074\)
Step-by-step explanation:
From the question we are told that
The probability of a tornado is \(p = 0.11\)
The sample size is \(n = 14\)
Since the number of tornadoes in any calendar year is independent of the number of tornadoes in any other calendar year and there can be only outcome so we can evaluate probability using binomial distribution.
The probability of a tornado not occurring is mathematically evaluated
\(q = 1 - p\)
=> \(q = 1 - 0.11\)
=> \(q = 0.89\)
The probability that there are fewer than 3 tornadoes in a 14-year period is mathematically represented as
\(P(X < 3) = P(X \le 3-1 = 2 ) = \left n } \atop {}} \right. C_2 * p ^2 q^{n- 2 } + \left n } \atop {}} \right. C_1 * p ^1 q^{n- 1 } + \left n } \atop {}} \right. C_0 * p ^r q^{n- 0 }\)
\(P(X < 3) = P(X \le 3-1 = 2 ) = \left 14 } \atop {}} \right. C_2 * (0.11) ^2 (0.89)^{14- 2 } + \left 14 } \atop {}} \right. C_1 * (0.11) ^1 (0.89)^{14- 1 } + \left 14 } \atop {}} \right. C_0 * (0.11) ^0 (0.89)^{14- 0 }\)
\(P(X < 3) = P(X \le 3-1 = 2 ) = 91 * 0.0121*0.247 + 14 * 0.11*0.2198 + 1 * 1 * 0.197\)
\(P(X < 3) = P(X \le 3-1 = 2 ) = 0.8074\)

Answers
Only the first and the last equations are correct
Here, we want to select three equations that could represent a step in solving the system of linear equations by substitution
We consider the given options one after the other
a) 4(8) + y = 6
By substituting the second equation in the first, we have this. So this is correct
b) y = 18
This is incorrect. From A, if we proceed to follow through the solution, we get that y = 6-32 = -26
c) 12x + y = 6
This is incorrect. We already have an expression in the first equation. This is similar albeit the difference in the coefficeint of x. We cannot have the same equation and as such, this cannot be correct
d) y = -24
This is not correct
By solution, y is -26 (6-32)
e) y + 32 = 6
This is correct
It is what we get by directly evaluating the first equation
