1. TRUE OR FALSE and explain. The coordinate pair (-3, 7) is the solution of the system of equations made up
of y = – 3x – 2 and y - 10 = 2/3(x-6).
Answer:
FALSE, when we plug in the coordinates (-3,7) in the equation, it isn’t true. Therefore, it isn’t the solution.
Step-by-step explanation:
You plug the coordinates (-3,7) in the equation and see if it’s true
Y= -3x-2
7=-3(-3)-2
7=9-2
7=7
Y-10=2/3(x-6)
7-10=2/3((-3)-6)

Answer:
? = 24, AB = 8.66 (square root of 75, 5 times the square root of 3)
Step-by-step explanation:
Since the whole length equals 27, we can subtract 3 to get 24. The proportion is a setup for geometric mean. This means cross-multiplying. X x X = X^2, 3 x 24 = 72. Square root both sides to get X by itself. [tex]3\sqrt{8} \\[/tex]. Use Pythagoreans to solve the rest. You are left with the square root of 75, or 5 times the square root of 3.

What’s the definition of dependent events?
Answer:
An event that is affected by previous events.
Step-by-step explanation:
I'm not sure but I think that's it.
Answer:
Dependent events depends on earlier events to decide if it is used or not.
An example of a dependent event can be the choice of ice cream. Before the person is asked what ice cream they want, they may have been asked what dessert they want. The event of "asking for a choice of ice cream", is dependent on the person stating that they wanted ice cream in the beginning. If they said anything else, they would not get to that question.

Austin checks the temperature at 10:00 pm. He notices if the temperature
Falls by 5 more degrees, it will break the record-low temperature for that date,
which is 26 degrees.
If y = the temperature in degrees at 10:00 p.m., which mathematical sentence
expresses the information above?
O A. T-5< 26
O B. T-5 > 26
O C. T+5> 26
O D. T+ 5 < 26
The correct mathematical sentence to represent the situation where the temperature at 10:00 pm (T), if reduced by 5 degrees, would break the record-low of 26 degrees, is T - 5 < 26, which is Option A.
The mathematical expression that represents the situation where Austin checks the temperature at 10:00 pm, and if it falls by 5 more degrees it will break the record-low temperature for that date, which is 26 degrees. The correct mathematical sentence that expresses this information is:
T - 5 < 26
This is because if the temperature at 10:00 p.m., represented by T, falls by 5 degrees and becomes less (<) than 26 degrees, it would break the record-low temperature.
Therefore, the answer is Option A.
A silo in the shape of a cylinder is partially filled with corn to cows. The corn fills 50% of the height of the silo. What is the approximate volume of the part of the silo that is filled with corn if the silo is 12ft in diameter and 60ft high?
The volume of the part of silo filled with corn is 3391.2 cubic foot.
Step-by-step explanation:
Diameter of the silo = 12ft.
Radius = 6 ft.
Height = 60ft.
Volume = π(r x r) h
= (3.14) (36) 60
= 6782.4 cubic foot
The corn is 50% filled. So,
Volume of corn filled = (50/100) (6782.4)
= 3391.2 cubic foot
The volume of the part of silo filled with corn is 3391.2 cubic foot.

You are riding in a taxi that charges a $10 flat fee, plus an additional $2 per
mile
Let C be the total cost of the ride and M be miles. Write an expression
relating C to M.
Answer:
C= 2M + 10
Step-by-step explanation:
In this equation, we will calculate the total cost. So, we'll start off with "C =" Then, we know tat the charge is $2 per mile so we'll add it and make C = 2M. Then, it states that the flat fee is 10 dollars which makes the equation
C = 2M +10.
Answer:
C = 2M + 10
Step-by-step explanation:
To write this equation, we will use slope-intercept form: y = mx+b
In this problem, C is y and M is x, so: C = mM + b
m is the slope, or the rate of change, and b is the y-intercept.
The y-intercept in this problem is the $10 flat fee.
The rate of change is the additional $2 per mile.
Let's input these values into our equation:
C = 2M + 10

Solve the system of equations below.
5x + 2y = 9
2x - 3y = 15
Answer:
(3,-3)
y= -3
x= 3
Step-by-step explanation:
5x+2y=9
2x-3y=15
solve the equation
x=9/5-2/5y
2x-3y=15
substitute the value of x into an equation
2(9/5-2/5y)-3y=15
distribute
18/5-4/5y-3y=15
subtract -4/5 to -3
18/5-19/5y=15
subtract 18/5 from both sides
-19/5=57/5
divide both sides by -19/5
y= -3
substitute the value of y into an equation
x=9/5-2/5(-3)
distribute
x=9/5+6/5
add 9/5 to 6/5

If the zeros are 1 and -4, what are the factors?
Answer:
(x - 1) and (x + 4)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a, x = b then the factors are
(x - a), (x - b) and the polynomial is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = 1 and x = - 4, thus the factors are
(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)

The question is about conditional probability. Assuming that the 2% who clicked the link are among the 7% who opened the email, around 29% of the people who opened the email clicked a link. Hence, option A is the correct answer.
Explanation:This question deals with the concept of conditional probability in mathematics, specifically percentages. Assuming that the 2% who clicked the link are among the 7% who opened the email, we want to find out what percent of the 7% clicked the link.
We calculate it like this:
First, remember that 2% of people clicked a link. That's our numerator.Then, remember that 7% of people opened the email. That's our denominator.Divide the numerator by the denominator to get the answer: 2 ÷ 7 = 0.2857 (rounded to four decimal places).So, around 29% (rounding up) of the people who opened the email clicked a link, which makes option A the correct answer.

A bag contains only red, green, brown and yellow marbles.
The probabilities of selecting each colour are shown below.
Red = 6x
Green = 2x
Brown = x
Yellow = 4x
Find the probability of selecting a brown marble.
To find the probability of selecting a brown marble, sum the total probability for all marble colors, solve for x, and then use the value of x to get the probability for brown which is 1/13.
Explanation:The question involves calculating the probability of selecting a marble of a certain color from a bag containing marbles of different colors, each with a different probability of being chosen. In this particular problem, we are given that the probabilities of selecting red, green, brown, and yellow marbles are 6x, 2x, x, and 4x, respectively.
Since these are the only colors in the bag, their probabilities must add up to 1 (the total probability), so:
6x + 2x + x + 4x = 1
Summing the multiples of x, we get:
13x = 1
Solving for x gives:
x = 1/13
We can now find the probability of selecting a brown marble, which is just x:
Probability of brown = x = 1/13.
The probability of selecting a brown marble from the bag can be found by dividing the number of brown marbles by the total number of marbles in the bag, which is 1/13.
Explanation:The probability of selecting a brown marble can be found by dividing the number of brown marbles by the total number of marbles in the bag. Since the bag contains four different colors of marbles, the total number of marbles is 6x + 2x + x + 4x = 13x. The number of brown marbles is x. So, the probability of selecting a brown marble is:
P(Brown) = x / (6x + 2x + x + 4x) = x / 13x = 1/13
