What is the subtraction property of equality?The subtraction property of equality states that subtracting the same number from both sides of an equation does not affect the equality, and hence it is used to isolate a variable that is adding on a side of the expression.
For this problem, to remove the term -7, we add 7 to both sides of the expression, hence the addition property of equality was applied.
In the other step, the multiplication property was applied, hence option D is the correct option for this problem.

A relationship between two expressions or values that are not equal to each other is called 'inequality.
Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade.
If the symbol ≥ or > is used, shade above the line.

There are 5 students 7 parents and 8 teachers in a room what's the probability that neither student and parent don't get picked?
Answers
The probability that neither student and parent don't get picked is equal to the value 2/5.
Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are. Statistics is the study of events governed by probability.
Given, there are 5 students 7 parents and 8 teachers in a room.
Total members in the room = 5+7+8
Total members in the room = 20
Total mem = 20
Probability of neither student and parent get picked = Probability of Teacher getting picked
Probability = Needed ones / Total members
Probability = 8 / 20
Probability = 2/5
Therefore, the probability that neither student and parent don't get picked is equal to the value 2/5.

The machinery in a cereal plant fills 350 g boxes of cereal. The specifications for the machinery permit for a certain amount of fill tolerance. It is found that the weights of filled cereal boxes are normally distributed with a mean of 350 g and a standard deviation of 4 g. What is the probability that a box of cereal is under filled by 5 g or more?
Answers
There is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.
To find the probability that a box of cereal is underfilled by 5 g or more, we need to calculate the probability of obtaining a weight measurement below 345 g.
First, we can standardize the problem by using the z-score formula:
z = (x - μ) / σ
Where:
x = the weight value we want to find the probability for (345 g in this case)
μ = the mean weight (350 g)
σ = the standard deviation (4 g)
Substituting the values into the formula:
z = (345 - 350) / 4 = -1.25
Next, we can find the probability associated with this z-score using a standard normal distribution table or a statistical calculator.
The probability of obtaining a z-score less than -1.25 is approximately 0.1056.
However, we are interested in the probability of underfilling by 5 g or more, which means we need to find the complement of this probability.
The probability of underfilling by 5 g or more is 1 - 0.1056 = 0.8944, or approximately 89.44%.
Therefore, there is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

Answers
For the time period of the projectile at least 192 feet above the ground is between 2 second and 6 second
Since s=128t-16t2, we want to know the 2 times where 128t-16t2=192, as those two values will be the begin and end times of the interval in question. We can rewrite that equation in standard quadratic equation form:
16t2-128t+192=0 or, simplified, 8t2-64t+96=0
or t2-8t+12=0
since it is now in quadratic form, we can solve using the quadratic formula:
t = 2 and 6
So the time period from approximately 2 second and 6 second has the projectile above 192 feet.

Which process will create a figure that is NOT congruent to the figure shown? Every point is moved 3 units to the right. Every point is moved 3 units right and 3 units up. Every point is moved so that it is 23 as far from the y-axis. Every point is moved to the opposite side of the x-axis but still the same distance from the x-axis.
Answers
Answer:
Every point is moved so that it is 2/3 as far from the y-axis
Step-by-step explanation:
Translation and reflection are "rigid" motions. They do not change the size or shape of the figure, so the resulting figure will be congruent with the original.
Dilation by a factor of 2/3 changes the size, so will not result in a congruent figure.

There is a bag filled with 4 blue, 3 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of exactly 1 red?
Answers
\(\displaystyle\frac{3}{16}\)
Step-by-step explanation:Probability represents the likelihood of an event occurring. Complex probability is the likelihood of a series of events occurring.
Independent Events
The question states that the marbles are replaced after being recorded. This means that the separate drawing of marbles is independent of each other. So, the probability of an event occurring does not change based on events that happened earlier.
This is important to this question because it means that probability does not change based on if the one red marble was drawn first or second.
Probability of a Red
First, we need to find the probability of drawing a red marble. Probability is represented as the number of successful outcomes (drawing a red) over the number of possible outcomes (number of marbles). Out of the total 12 marbles, 3 of them are red. So, the probability of drawing a red is \(\displaystyle\frac{3}{12}\).
The Complement
In probability, the complement is the likelihood of an event not occurring. So, in this situation, the complement is the likelihood of not drawing a red. Out of the total 12 marbles, 9 are NOT red. So, the complement is \(\displaystyle\frac{9}{12}\).
Complex Probability
To find the probability of 2 different events both occurring, multiply the probabilities together.
\(\displaystyle\frac{3}{12}*\frac{9}{12}=\frac{27}{144}\)Then, we can simplify the fraction by dividing by 9
\(\displaystyle\frac{3}{16}\)This means that the probability of drawing exactly one red is 3/16.
Because the first marble is replaced P(red) is always 3/12 = 1/4 and P(not red) = 9/12 = 3/4
P(red then not red) = 1/4 x 3/4 = 3/16
P(not red then red) = 3/4 x 1/4 = 3/16
P(exactly one red) = 3/16 + 3/16 = 6/16 = 3/8
[ P(two reds) = 1/4 x 1/4 = 1/16 and P(no reds) = 3/4 x 3/4 = 9/16 so P(one red) = 1 - 1/16 - 9/16 = 6/16 = 3/8]
