Assume that it is equally likely for a child to be born a boy or a girl and that the Lin family is planning on having 2 children. How many elements are
there in the samples space for the genders of the two children?
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.

Given the triangle above, solve for x.
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.
In the slope-intercept form, which variable

What is the slope of the line through (-10,1) and (0,-4) ?
Answer:
-5/10 or -1/2
Step-by-step explanation:
What is the slope of the linear function represented in
the table?
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
There are 72 female performers in a dance recital. The ratio of men to women is 2:9. How many men are in the dance recital?
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:(

r = x^2/y work out the value of r
Answer:
r=244745.8 (approximately)
Step-by-step explanation:
r=x²/y
ry-x²=0
r(59000)-(380000)²=0
r=380000²/59000
r=144400000/59
r=244745.8 (approximately)
Last year, Ivy's pant measured 12 inches. This year, her plant is 75% taller.
How many inches did her plant grow?
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

Solve the equation.
6W + 5y = 2z solve for y
Pls help!!!
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:
side HA and side AT
Step-by-step explanation:
Solve the system of equations by substitution.
X + y = 21
y = 6x
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
What is the next term of the arithmetic sequence? 1, 3, 5, 7, 9
Answer:

What is the solution for the equation 4x – 10 = 2x?
Answer:
5x
Step-by-step explanation:
subtract 4x fromboth sides
4x-10=2x
-4x -4x
divide both sides by -2
-10=-2x
-10/-2=-2x/-2
