Answer:

The plant grew 9 more inches since last year.

Step-by-step explanation:

75% of 12 is 9 and the initial plant growth was 12 inches.

So, the plant grew 9 more inches since last year.

The plant is now 21 inches.

Answer:

9

Step-by-step explanation:

Divide 12 by 4 to get 25% = 3

25% x 3 = 75%

3 x 3 = 9

subtract 4x fromboth sides

4x-10=2x

-4x     -4x

divide both sides by -2

-10=-2x

-10/-2=-2x/-2

Answer:

48

Step-by-step explanation:

72 ÷ 3 = 24

so you know that the men is 24 × 2 = 48

48:72 = 2:3

i looked it up and it says x=4 and theres 12 men but i dont think that helps im so sorry i couldnt find anything:(

Step 2: Solve for v

Every triangle has a total of 180 (when you add all three angles together), and the same would be for a straight angle, or two angles formed by am angle bisector (DC). 180-33=147, so the top part of C would be 147, which isn't necessarily needed, but that'd be how to solve that. A+B+C=180. A+2x+C=180. A would be 33 because AB and DC (segments) are parallel, and the segment bisector AE is a straight line, so 33+2x+C=180. 180-33=147/2=73.5, if I did that correctly.

Answer: It depends on if the girl genes are dominant or if the boy genes are recessive. If the girl genes are more dominant then Lin is probably going to have more girls than boys.

Answer:

Y = 2/5z-6/5w

Step-by-step explanation:

6W + 5y = 2z

1. Subtract 6W from both sides

2. 5y = 2z-6W

3. Divide both sides by 5

4. y = 2/5z-6/5W

Answer:

im not 100 percent sure but i think its x=71

Answer:

Step-by-step explanation:

The problem with this question would be resolved in a New York second if people learned what an exterior angle was. x is an exterior angle. Exterior angles have their own set of properties. One of them is that they are the sum of the two interior angles not supplementary to the given exterior angle.

In the diagram above the supplement to x has no marking. It is not an exterior angle. x is the exterior angle.

A triangle has Interior sums of 180o. Everyone here seems to understand that. What is not understood is the properties of x and the other two exterior angles. Exterior angles polygons of any number of sides have exterior angles that add up to 360 degrees. The 360 degrees does not indicate that they are not circles.

So the answer to this question is that x = 64 + 45 = 109. If you put anything else in, you will get it wrong.

This question checks to see if you understand the difference between an exterior angle and an interior angle. 71 is not the answer. It is not even the second best answer. It is just the third interior angle.

what's the question sweetie?

Answer: 1/7

Step-by-step explanation: The points create a posotive line so the answer has to be posotive. You then have to look at the rise over run. (0,1) is 1 unit higher than (-7,0) and the run is the ditance between the 2 x exvalues. 7. Rise/run = 1/7

Answer:

In this case, adding 2 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) . This is the formula of an arithmetic sequence.

Answer:

x = 3

y = 18

Step-by-step explanation:

you replace y with 6x

x + 6x = 21

combine like terms

7x = 21

divide both sides by seven

x = 3

then you plyg 3 into the other equation

y = 6(3)

y= 18

Answer:

x=3

y=18

Step-by-step explanation:

x+y=21..........equation 1

or,x=21-y......equation 2

y=6x.......equation3

substituting the value of x in equation 3

y=6(21-y)

or,y=126-6y

or,7y=126

y=18

again,substituting the value of y in equation 2

x=21-y

or,x=21-18

x=3

x=3,y=18

Answer:

C: 31% of the variation in the GPA is accounted for by the linear relationship with number of absences.

Step-by-step explanation:

right on edge

The correct interpretation of the value of r² in this context is 31% of the variation in the GPA is accounted for by the linear relationship with the number of absences.

The interpretation of the value of r² in the context of the relationship between a student's number of absences (x) and their grade point average (GPA) (y).

First, what is r²? The coefficient of determination, denoted as r², is a statistical measure that represents the proportion of the variance (variation) in the dependent variable (GPA) .

That can be explained or predicted by the independent variable (number of absences) in a linear regression model.

Here, the value of r² is 31%. This means that 31% of the total variability in the GPA scores of the 15 randomly selected students can be explained by the linear relationship with the number of absences.

31% of the differences in GPAs among the students can be attributed to the differences in their number of absences.

The remaining percentage (100% - 31% = 69%) represents the unexplained or residual variation in the GPA scores.

This unexplained variation could be due to other factors not considered in the linear relationship, such as individual study habits, natural academic ability,

or other variables that were not part of the data analysis.

The interpretation is that 31% of the variation in the GPA scores can be accounted for by the linear relationship with the number of absences, while 69% of the variation remains unexplained by this relationship.
