Answer:
3(y + 5)
Step-by-step explanation:
Factorization is a process which is like the opposite of expansion. It involves factoring out the common factors from the given terms.
Thus to factorize 3y + 15, we have to consider the common factor(s) of the two terms. The common factor is 3 because the two terms (i.e 3y and 15) are both divisible by 3 only.
So that:
3y + 15= 3([tex]\frac{3y}{3}[/tex] + [tex]\frac{15}{3}[/tex])
= 3(y + 5)
The outcome of the process is 3(y + 5).

Step 1: Define Systems
y = 2x + 1
x + 3y = 10
Step 2: Solve for x
Substitution
Substitute in y: x + 3(2x + 1) = 10Distribute 3: x + 6x + 3 = 10Combine like terms: 7x + 3 = 10[Subtraction Property of Equality] Subtract 3 on both sides: 7x = 7[Division Property of Equality] Divide 7 on both sides: x = 1Step 3: Solve for y
Define original equation: y = 2x + 1Substitute in x: y = 2(1) + 1Multiply: y = 2 + 1Add: y = 3Step 4: Find difference
y = 3
x = 1

Answer:
[tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex] =
Step-by-step explanation:
We need to find the value of [tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex]
The LCM of 3 and 5 is 15. So,
[tex]\dfrac{x}{3}+\dfrac{x}{5}=\dfrac{5x+3x}{15}[/tex]
[tex]=\dfrac{8x}{15}[/tex]
So, the value of [tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex] is equal to [tex]\dfrac{8x}{15}[/tex].
Jennie charges $200 per passenger for a sunset sailing
tour on her catamaran, while Paul charges $250 per
passenger. We can define the amount of money each
person earns per cruise as a random variable.
Let A = the amount of money Jennie earns and let B =
the amount of money Paul earns.
What is the mean of the sum and the mean of the
difference of the amount of money that Jennie and
Paul earn on a randomly selected cruise?

Answer:
1692.5 and -232.5

The mean of the sum would be as follows:
1692.5
The difference of the amount of money earned by Jennie and Paul would be:
-232.5
Mean
Given that,
Money earned by Jennie(A) [tex]= 200X[/tex]
Money earned by Paul(B) [tex]= 250Y[/tex]

Volunteers for a human performance study were randomly divided into two groups. The first group had their flexibility measured in the morning after a short meditation session while the second group had their flexibility measured in the afternoon with no previous meditation session. The flexibility scores of the two groups were compared. This experiment was not double-blind because:
a. some of the volunteers stretched before they went to the study location.
b. volunteers were allowed to keep their eyes open while having their flexibility measured.
c. volunteers were randomized into the two groups.
d. the volunteers knew whether they had meditated before having their flexibility measured.
Answer:
C
Have a wonderful day!
The experiment was not double-blind because volunteers were randomized into the two groups. The correct option is c.
What is a double-blind experiment?A type of clinical experiment where neither the research team nor the subjects are aware of the treatment or intervention they are receiving until the trial is complete. As a result, the study's findings are less likely to be skewed.
Because neither the participant nor the clinician is aware of who has received what treatment, double-blind studies are regarded as the most trustworthy sort of research. This is done in an effort to lessen bias and the placebo effect.
Both the researchers and the test subjects must be uninformed of who is receiving the treatment and who is receiving a placebo in a double-blind trial.
Therefore, the correct option is c. volunteers were randomized into the two groups.

Since, both the triangles (small and large) given in the picture are similar,
Their corresponding sides will be in the same ratio.
By applying this property,
