The answers to your questions are as follows :
The situation with a probability closest or equal to 0 is rolling a number: (A) greater than 5. The model which shows the probability of choosing a multiple of 4 is: ( B ) [tex]\frac{2}{10}[/tex] (2/10)The only survey that would not be valid with a sample of seventh-grade classmates is : ( B ) Bank that offer the most services.The probability of choosing a red marble, then a white marble if the marbles are replaced is : ( A ) 7/10.The probability of spinning the following. P(not 7) = 7/8Meaning of ProbabilityProbability is a branch of mathematics that deals with the degree of occurrence of an event.
1) The situation with a probability closest or equal to 0 is rolling a number: (A) greater than 5.
Because: there is only one number greater than 5 in that list (which is 6)
2) The model which shows the probability of choosing a multiple of 4 is: ( B ) [tex]\frac{2}{10}[/tex] (2/10)
Because: there are only two multiples of 4 that can be picked from number 1-10
3) The only survey that would not be valid with a sample of seventh-grade classmates is : Bank that offer the most services.
Because: they are not working and might have little or no idea about banking services.
4) The probability of choosing a red marble, then a white marble if the marbles are replaced is : 7/10.
where the probability of picking a red marble is = [tex]\frac{3}{10}[/tex]
The probability of picking a white marble is = [tex]\frac{4}{10}[/tex]
since the marbles were replaced : [tex]\frac{3}{10}[/tex] + [tex]\frac{4}{10}[/tex] = [tex]\frac{7}{10}[/tex]
5) The probability of spinning the following. P(not 7) = 7/8
The probablity of picking a 7 is = [tex]\frac{1}{8}[/tex]
The probability of not is = 1 - probability of picking 7

The selling price of the Robertsons family house dropped from $500,000 to $250,000. What was the percent decrease in the value of their home?
( please solve, NOT in proportion please!! )
Answer:
50%
Step-by-step explanation:
You can literally do it mentally lol
$500,000
- $250,000
$250,000
so by common sense, it's 50%
Hope it helped!
Answer:
50%
Step-by-step explanation:
50% of the value of the house dropped.
So 50% of 500,000.
50 percent *500000 =( 50:100)*500000 =( 50*500000):100 =25000000:100 = 250000How would three billion, nine hundred seventy-six thousand, twelve be written in standard form?

kevin completed 10 problems of his homework during lunch this is 2/7 of the total assignment how many problem was Kevin assigned for homework
Answer:
35 problems
Step-by-step explanation:
We know that 10 problems are 2/7 of his total assignment, so we can set up the following equation,
[tex]\frac{10}{x\\} = \frac{2}{7}[/tex]
(side note: x is the denominator because we don't know how many problems it is out of yet)
We can cross multiply which gives us: (7x10) and 2(x)
70 = 2x (set them equal)
x = 35 (divide 70 by 2)
Hope this helps!

The sum of all but one interior angle of an octagon is 776°. The measure of the final interior angle is ___ degrees.
the sum of all interior angles in a polygon, regular or not is
180( n - 2), n = number of sidesnow, this is an octagon, with 8 sides, so it has a total of interior angles of 180( 8 - 2) or 180(6) = 1080.
we know the sum of all BUT one is 776°, so the last one must be 1080° - 776° = 304°.

What is the spatial relationship between a rectangle and a parallelogram?
Answer:
a rectangle is a parallelogram as the parallogram is made up of 2 triangles and a smaller rectangle. When the rectangle is divided into 2 triangles and another small rectangle, and is then being put together with the triangles on each side, it will be a parallelogram.
Step-by-step explanation:
Explanation:
A rectangle has the following properties:
Has 4 sidesHas 4 right anglesOpposite sides lengths are equal.Diagonals of rectangle are equal.Opposite sides are parallel.A parallelogram has the following properties:

Step-by-step explanation:
Prisms A and B are similar. The volume of prism A is 375cm3. The volume of prism B is 648cm3. The surface area of prism A is 250cm2. Work out the surface area of prism B.
Answer:
We have the length, width, and height of the rectangular prism, so we can calculate V=l×w×h=20cm×10cm×10cm=2,000cm3 V = l × w × h = 20 cm × 10 cm × 10 cm = 2 , 000 cm 3
The surface area of Prism B is approximately 367.25 cm^2.
Since Prisms A and B are similar, their corresponding sides are in proportion, and their volumes are related by the cube of the scale factor between them.
Let the scale factor between Prism A and Prism B be k. Then:
Volume of Prism A / Volume of Prism B = (Side length of Prism A / Side length of Prism B)^3
Given that the volume of Prism A is 375 cm^3 and the volume of Prism B is 648 cm^3, we can set up the equation:
375 / 648 = (Side length of Prism A / Side length of Prism B)^3
Now, let's solve for the scale factor (k):
k^3 = 375 / 648
k^3 = 0.5787037037
k ≈ 0.825 (rounded to three decimal places)
Now, since the surface area of a prism is proportional to the square of its side length, we can find the ratio of the surface areas:
(Surface area of Prism A / Surface area of Prism B) = (Side length of Prism A / Side length of Prism B)^2
Given that the surface area of Prism A is 250 cm^2, we can find the surface area of Prism B:
Surface area of Prism B = Surface area of Prism A / (k^2)
Surface area of Prism B = 250 / (0.825^2)
Surface area of Prism B ≈ 250 / 0.680625
Surface area of Prism B ≈ 367.25 cm^2
Therefore, the surface area of Prism B is approximately 367.25 cm^2.

Which pairs of angles are supplementary?
1 and 6
5 and 7
5 and 8
2 and 3
Answer:
1 and 6
5 and 7
Step-by-step explanation:
Supplementary angles are 180 degrees and so is a linear pair
1 and 6 add up to 180 degrees meaning they are supplementary. Angle 1 and angle 2 are a linear pair so 180-120=60 which is the degree of angle 1, angle 2 corresponds to angle 6, so angle 1 + angle 6 would equal 180 degrees. (120+60)
5 and 7 are a linear pair which automatically makes them supplementary
The others are vertical angles which don't add up to 180. (120+120=240)(60+60=120)

Solution:-The equation of this line is written in Slope-Intercept Form, which looks like so:-y=mx+bIn this formula, m stands for the slope of the line, and b stands for the y-intercept.Please remember that the slope is the line's rise (the amount of units we move up, or "rise" divided by its run (the amount of units we move left or right, and the y-intercept is the point where the line intersects the y-axis. (0, b)Also, please notice that m is the coefficient of x, and b is the constant.Therefore, the slope of the line is equivalent to -4, and the y-intercept is (0, -3).Hope it helps.
Do comment if you have any query.
Answer:
Slope: 4; y-intercept: -3
Explanation:
To find the slope of the line, we will look at the number in front of x.
That number is -4. Hence, the slope is -4
Now, the y-intercept is the constant.
The constant is -3.
Hence, the y-intercept is -3.
