Step-by-step explanation:
2x -5y = -6 === (1)
4x-3 =-12 ====(2)
From (2), 4x= -12 +3

A police officer believes red cars speed more often than any other color car. During his 25 shifts this month, he records the number of speeding tickets he writes to red and non-red cars.
a. Determine whether the following statement is true or false.
1. The police officer is conducting an experiment.
b. All of the following variables could be confounding variables EXCEPT for which one?
a. time of day
b. color of car
c. location
d. the police officer
Answer:
Step-by-step explanation:
a. Yes, the following statement is true. The police officer is gathering data by writing down all the speeding tickets and seperating them into two categories, red and non-red cars. He can later analyze this data and compare them to determine whether or not his hypothesis is true.
b. The color of the car is the only variable that would not be a confounding variable in this scenario. This would instead be the independent variable and does not in any way affect the dependent variable which would be the number of speeding tickets received.

Which inequality is shown in this graph? (0, 2) (-1,-2)
A. y2-4x+ 2
B. yz 4x + 2
C. ys - 4x + 2
D. y = 4x+2
Answer:
D) y = 4x + 2
Step-by-step explanation:
Explanation:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2

choose the set of equivalent fractions that correctly uses the LCD for these fractions 3/4 and 1/6
Answer: 9/12, 2/12
Step-by-step explanation:
Start by writing multiples of 6 and 4
4: 4, 8, 12
6: 6, 12, 18
Did you see the multiple that both numbers have? Yup, it's 12. So that has to be your denominator for both fractions. This is because you have to have the LEAST COMMON Denominator (LCD). So both numbers have 12 in common as one of their multiples and, it's the least common one because there are no numbers that come before it that are common for both numbers. Now, you just have to change the denominators of both fractions into 12. To do that to 3/4, just multiply the top and bottom by 3 to get 9/12. To do that to 1/6, just multiply the top and bottom by 2 to get 2/12. Hope this helps!
NOTE: REMEBER THAT WHATEVER YOU DO TO THE TOP OF A FRACTION, YOU HAVE TO DO IT TO THE BOTTOM TOO (AND VICE VERSA)

Rodney packs 4 shirts for a trip at random. The closet contains 10 shirts: 5 striped, 3 plaid, 2 solid colored ones. What is the probability that he chose 2 striped and 2 plaid
Answer:
1 / 7
Step-by-step explanation:
Given :
Number of shirts in closet = 10
Number of striped shirt = 5
Number of plaid = 3
Probability of choosing 2 plaid shirts and 2 stripped shirt
Probability = required outcome / Total possible outcomes
Total possible outcomes = 10C4
Required outcome :
2 plaid shirt from 3 = 3C2
2 stripped shirts from 5 = 5C2
Hence,
P(choosing 2 plaid and 2 stripped shirt) :
(3C2 * 5C2) / 10C4
Recall:
nCr = n! / (n-r)!r!
Using calculator :
(3C2 * 5C2) / 10C4
= (3 * 10) / 210
= 30 / 210
= 1 / 7

I think it would be c 160
Step-by-step explanation:
Answer:
The answer is C) 160ft2
Step-by-step explanation:
I got the answer because if you multiply the number of feet that make up that one side of the tent, you get 40. However, you need the to find out the feet of the whole tent, and there are four sides of the tent, so you'd have to multiply 40 by four to get the total amount of feet for the whole tent which comes out to 160.
Martha wants to investigate whether her 12-sided number cube is fair. In the first 10 rolls of the number cube, the number 2 was rolled 4 times. After rolling the number cube 200 times, 2 was rolled 18 times. Which statement regarding the probability of rolling a 2 on this 12-sided number cube is true?
Answer:
The number cube as 12 sides, and if it is fair, then each one of the 12 numbers should have the same probability of being rolled.
This means that the probability of rolling a 2 should be equal to 1/12 = 0.0833
Remember that this is theoretical, we should expect to see this probability with a really high number of rolls.
On the first experiment, there were 10 rolls, and the number 2 showed up 4 times, then based on this, the relative frequency is equal to the quotient of the number of times that the 2 was rolled (4) and the total number of rolls
p = 4/10 = 0.4
This differs with the theoretical probability, we should expect that as we increment the number of rolls, the experimental probability should approximate to the theoretical one.
In the second experiment, we have 200 rolls, and the 2 was rolled 18 times. Then the experimental probability of rolling a 2 is:
p = 18/200 = 0.09
This is almost the same as the theoretical one.
Then we could conclude that the probability of rolling a 2 seems to be the one of fair dice.
We can conclude that the 12-sided number cube is fair
The given parameters are:
4 outcomes of 2 in 10 rolls.18 outcomes of 2 in 200 rolls.The theoretical probability of 2 in a 12-sided number cube is:
[tex]\mathbf{P(2) = \frac{1}{12}}\\[/tex]
Express as decimals
[tex]\mathbf{P(2) = 0.083}[/tex]
The experimental probability of 2 in after 200 rolls is:
[tex]\mathbf{P(2) = \frac{18}{200}}[/tex]
Express as decimals
[tex]\mathbf{P(2) = 0.09}[/tex]
By comparing the experimental and the theoretical probabilities, we can see that: 0.08 and 0.09
Hence, we can conclude that the 12-sided number cube is fair

C 11
D 14
Answer:
D) 14
The value '14' is NOT a possible value of x
Step-by-step explanation:
Explanation:-
Given that the interval
3 < x < 12
This means the value of 'x' lies between the '3' and '12'
←3 4 5 6 7 8 9 10 11 12→
