By direct evaluation, we will see that the pair (8,2) is not a solution of the system of equations.
Evaluating a system of equations.
A given point is a solution of a system of equations if and only if it is a solution for both equations, then to see if (8, 2) is a solution of the given system, we need to replace the values in both equations and see if it is a solution of each one.
For the first one we have:
x - y = 6
8 - 2 = 6
6 = 6
So (8, 2) is a solution of the first equation.
For the second one we have:
2x - 10y = 4
2*8 - 10*2 = 4
16 - 20 = 4
-4 = 4
Note that this equation is false, then the point (8, 2) is not a solution for the second equation, then the point is not a solution for the system of equations.

For two binomial random variables, one with p = 0.3 and the other with p = 0.7, which one would have the higher value at the 50th percentile of the associated distribution?
a. 0.7
b. 0.3
c. Need More Information
d. Neither, the Values Would be Equal
Answer:
d
Step-by-step explanation:
To use the binomial distribution, we need p and 1 - p
and so, since 1-0.3 is same as 0.7
for the 50th percentile, we have that the values of the two are equal
The 50th percentile in this case is that probably, we are selecting 50 out of a total of 100

What is the image of the point (-2,3) after a rotation of 90° counterclockwise about the origin?
Answer:
use the equation (x,y)---->(-y,x)
(-2,3)----> (3,-2)
The image of the point (-2,3) after a rotation of 90° counterclockwise about the origin will be (3, 2).
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
The point (-2, 3) is in the second quadrant. After a rotation of 90° counterclockwise about the origin, the point will be in the first quadrant.
After the rotation, the coordinate of the points will get swapped and in the first quadrant, the value of the coordinate will be positive.
The image of the point (-2,3) after a rotation of 90° counterclockwise about the origin will be (3, 2).

Which expression results in a rational number?
4
the fourth expression is a rational
The expression results in a Rational number is √2.√18 .
What is rational number?A rational number is "a real number which is in the form of p/q, where q ≠ 0.The decimal expansion of any rational number is terminating or repeating".
What is irrational number?A irrational number is "a real number which is not in the form of p/q, where q ≠ 0.The decimal expansion is non-terminating and non-repeating at any point".
According to the question,
1) √2.√18
=√2.√(9.2)
= √2.3.√2
= 3.2
= 6.
Hence, √2.√18 satisfy the given definition of rational number. The expression √2.√18 is a rational number.
2) √2 + √2 = 2√2 = 2.82842712..... The expression√2 +√2 has decimal expansion which is non-terminating and non-repeating at any point then it is irrational number. hence, √2 + √2 is not a rational number.
5.√5 = 11.1803399.... The expression5√2 has decimal expansion which is non-terminating and non-repeating at any point then it is irrational number. hence, 5√2 is not a rational number.
3√2 + 2√3=7.87831518.... The expression3√2 +2√3 has decimal expansion which is non-terminating and non-repeating at any point then it is irrational number. hence, 3√2+2√3 is not a rational number.

A gallon of lemonade contains one cup of sugar. How many tablespoons of sugar are in 1.5 pints of lemonade?
Answer:
the number of table spoons of sugar is 48
Step-by-step explanation:
The computation of the number of table spoons of sugar is shown below:
As we know that
1 cup = 16 tablespoon = 8 ounces
1 gallon = 4 quarts
1 pint = 2 cups = 16 ounces
1 quart = 4 cups (2 pints) = 32 ounces
Given that
One gallon = one cup of sugar
One gallon = 16 tablespoons
Now for 1.5 pints, it is
1.5 pints = 3 cups
= 16 × 3
= 48 tablespoons
Hence, the number of table spoons of sugar is 48
Kendra sold 200 shares through her broker in June 8. The price per share was $22.10. The broker charged her a 0.5% commission on the total value. What was Kendra’s return on the trade?
Answer:
A. $4397.9
Step-by-step explanation:
We are given that Kendra sold 200 shares and that the price per share was $22.1
This means that:
Total value = 200 * 22.1 = $4420
Now, we know that the broker charged 0.5% commission on the total value
This means that:
Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1
Therefore,
Kendra's return = Total value - broker's charge
Kendra's return = 4420 - 22.1 = $4397.9
