If you roll a fair number cube 30 times, what is the experimental probability of rolling a 2
Answers
Answer:
1/6 chance or 16.667% chance
Step-by-step explanation:
a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6

A student made two patterns to show multiplication of a declmal by powers of ten. The equations shown for both patterns are incorrect. Pattern A 3.675 • 10 = 3.6750 3.675 - 100 = 3.67500 3.675. 1.000 = 3.675000 Pattern B 3.675.0.1 = 3.0675 3.675 -0.01 = 3.00675 3.675 -0.001 = 3.000675 explain why the equations in each of the patterns are false. include in your explanation the values that should appear on the right side of each equation in both patterns to make the equations true.
Answers
Answer:
Step-by-step explanation:
The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
How to solve the decimals?
From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.
In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.
Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
the table shows the results of rolling a number cube labeled 1 through 6 30 times
based on the results, if the cube roles 200 times, how many times is it expected to land on 1
Answers
Answer:
40 times
Step-by-step explanation:
To figure this out, divide 6 by 30, then multiply by 200
(6/30)200 = 40
This also works: (200/30)6 = 40
We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.
Find the equation of a line which is parallel to the line with the equation 2x + y = 4 and
which passes through the origin.
Answers
Answer:
y = -2x
Step-by-step explanation:
Given
2x + y = 4Passes through the origin (0, 0)Solving
Rewriting the equation
2x + y = 4y = -2x + 4New equation
The slope of the new line is the same (-2) because it is parallelThe y-intercept is (0, 0)⇒ y = mx + b [m = slope, b = y-intercept]
⇒ y = -2x + 0
⇒ y = -2x
Answer:
2x+y=0
Step-by-step explanation:
Given:
[tex]\displaystyle \large{2x+y=4}\\\displaystyle \large{y=-2x+4}[/tex]
To find:
The equation of line that’s parallel and passes through origin point.Parallel Definition:
Both lines have same slope.Slope-Intercept:
[tex]\displaystyle \large{y=mx+b}[/tex]
m = slopeb = y-interceptTherefore, another line is:
[tex]\displaystyle \large{y=-2x+b}[/tex]
Since the line passes through origin point which is (0,0). Substitute x = 0 and y = 0 in the equation:
[tex]\displaystyle \large{0=-2(0)+b}\\\displaystyle \large{b=0}[/tex]
Therefore, the equation is:
[tex]\displaystyle \large{y=-2x}[/tex]
Convert back to standards form:
[tex]\displaystyle \large{2x+y=0}[/tex]
Therefore, another line that is parallel to [tex]\displaystyle \large{2x+y=4}[/tex] is 2x+y=0

how do you find the fist step to solving the system of equations x+y=8 and 3x-2y=-6
Answers
Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6

2 units left2 units downreflection across the y-axisStep-by-step explanation:
The letters designating the original figure, RSTU, start at the bottom of the figure and proceed clockwise around it. The letters designating the image, R'S'T'U' start at the bottom and proceed counterclockwise around it. This tells you ...
the figure has been reflected once (CW-CCW order is reversed)the line of reflection is a vertical line (up-down orientation hasn't changed)__
The fill-in for the answer tells you that translation takes place before reflection. To figure out how much translation is needed, you need to know the line of reflection.
Line of ReflectionYou can look at the reflection choices to see where the line of reflection is. We're guessing that the only vertical line choice is the y-axis. (If the line of reflection is x=1, there doesn't need to be any horizontal translation.) If the image is reflected across the y-axis, the point R' moves from (-3, 0) to (3, 0). This is where R' is reflected from.
TranslationThe point R is at (5, 2). To move R from (5, 2) to (3, 0) prior to reflection, the x-coordinate needs to decrease by 2 (from 5 to 3), and the y-coordinate also needs to decrease by 2 (from 3 to 0). That is, the point R must be translated left 2 and down 2 to get it to (3, 0).
__
R'S'T'U' is the image of RSTU after translation 2 left, 2 down, and reflection across the y-axis.
