Step-by-step explanation:
A fair 6-sided die is rolled five times. What is the probability that the sequence of rolls is 3,4,1,2,6
Answer:
Step-by-step explanation:
probability = number of favorable outcomes/total number of outcomes
To find compound probability multiply all the probabilities together.
p(3) = 1/6
p(4) = 1/6
p(1) = 1/6
p(2) = 1/6
p(6) = 1/6
Multiply all of them together.
1/6 x 1/6 x 1/6 x 1/6 x 1/6 = 1/7,776
or
[tex](\frac{1}{6} )^5 = \frac{1}{7,776}[/tex]

don't spam .-.
thankyou ~
Answer:
[tex]x=-\frac{4}{9}[/tex]
Step-by-step explanation:
2x + 1 - 4x = 7x +5
First, take 7x to the left side.
2x + 1 - 4x - 7x = 5
Now take 1 to the right side.
2x - 4x - 7x = 5 - 1
Now combine like terms.
-2x - 7x = 4
-9x = 4
Now divide both sides by -9.
x = - 4/9
Answer:
2x+1-4x=7x+5
-->2x-4x-7x=5-1
-->-2x-12x=4
-->-9x=4
-->x=-4/9
-->x=-4/9

By analyzing the data tables given, we will see that:
1) The range is 28.
2) The graph can be seen at the end.
3) There are clusters at 16 and 17, and 25 is an outlier.
4) The range decreases almost by 50%.
How to get the range for the data?
The range is defined by the difference between the largest and smallest values from the data set.
In this case, the largest is: 95The smallest is: 67So the range is: R = 95 - 67 = 28
The correct option is D.
How to make a line plot?For each time that a number appears, you need to make a dot above the correspondent value.
The graph can be seen below.
3) we have clusters on 16 and 17, and as you can see, the value 25 is really away of the rest of the values, so we have a gap, and 25 is an outlier.
4) With the 25, the range is:
25 - 16 = 9
If we remove it, the range is:
21 - 16 = 5
So the range decreases almost by a 50%.

Landon is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes are there if he spins a spinner with four equal-sized sections labeled Red, Green, Blue, Orange and spins a spinner with three equal-sized sections labeled Walk, Run, Stop?
The total number of ways this can be done is 144 ways
How to determine the number of outcomesGenerally, the total outcomes that are there when n objects are spinned is expressed as n!
n! = n(n-1)(n-2)!
If he spins a spinner with four equal-sized sections labeled Red, Green, Blue, Orange and three equal-sized sections labeled Walk, Run, Stop, the total outcome is expressed as:
Total outcome = 4! * 3!
Total outcome = 24*6
Total outcome = 144 ways
Hence the total number of ways this can be done is 144 ways

Gabrielle is 15 years older than Mikhail. The sum of their ages is 81. What is Mikhail's age?
Answer:
33
Step-by-step explanation:
let g be Gabrielle age
m be mikhail age.
So according to this problem,
[tex]g + m = 81[/tex]
[tex]m + 15 = g[/tex]
Subsitue m+15 for g.
[tex](m + 15) + m = 81[/tex]

A rectangle has an area of 31.2 square millimeters and a heigt of 5.2 millimeters. What is the length of the base
Answer:
6 millimeters
Step-by-step explanation:
The formula for a rectangle is length * height = area.
Since we know the area and height, we can plug it in to the formula:
length * 5.2 = 31.2
So the length is just dividing 5.2 in 31.2 which gives 6 millimeters.

Does 3(7x +7) + 5x represent a number that is greater than, less than, or equal to 5(5x + 10)
Answer:
Step-by-step explanation:
from
3(7x +7) + 5x = 5(5x + 10)
21x+21+5x = 25x + 50
26x + 21 = 25x + 50
26x-25x +21 = 50
1x+21 = 50
1x =50-21
x = 29
equal when x= 29
try to x> 29 such as 30
3(7(30) +7) + 5(30) ? 5(5(30) + 10)
1470 ? 800
so greater than when x >29
finally
less than when x<29
Answer:
When x = 29: the expressions are equal
When x < 29: 3(7x + 7) + 5x is less than 5(5x + 10)
When x > 29: 3(7x + 7) + 5x is greater than 5(5x + 10)
Step-by-step explanation:
Given expressions:
3(7x + 7) + 5x5(5x + 10)Expand both expressions:
3(7x + 7) + 5x
⇒ 21x + 21 + 5x
⇒ 26x + 21
5(5x + 10)
⇒ 25x + 50
Equate the expanded expressions and solve for x
26x + 21 = 25x + 50
⇒ 26x - 25x = 50 - 21
⇒ x = 29
Therefore, the expressions are equal when x = 29
When x < 29: 3(7x + 7) + 5x < 5(5x + 10)
When x > 29: 3(7x + 7) + 5x > 5(5x + 10)
A line passes through ( – 8,6) and ( – 2, 3).
Find the y-intercept, b, of the line.
Answer:
[tex]\displaystyle [0, 2][/tex]
Step-by-step explanation:
First, find the rate of change [slopes]:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{8 - 2} = m; \frac{-3}{6} \\ \\ -\frac{1}{2} = m[/tex]
We now plug the above information into the Slope-Intercept Formula. It does not matter which ordered pair is selected:
[tex]\displaystyle y = mx + b \\ \\ 3 = -\frac{1}{2}[-2] + b \hookrightarrow 3 = 1 + b; \boxed{2 = b} \\ \\ y = -\frac{1}{2}x + 2[/tex]
OR
[tex]\displaystyle y = mx + b \\ \\ 6 = -\frac{1}{2}[-8] + b \hookrightarrow 6 = 4 + b; \boxed{2 = b} \\ \\ y = -\frac{1}{2}x + 2[/tex]
Therefore, the line passes through the y-intercept of [tex]\displaystyle [0, 2].[/tex]

The graph is stretched vertically by a factor of 4 and shifted down 1 unit.
The graph is compressed horizontally by a factor of 4 and shifted left 1 unit.
Answer:
The graph is stretched horizontally by a factor of 4 and shifted up 1 unit
Step-by-step explanation:
The effect of transforming the function is (b) The graph is stretched horizontally by a factor of 4 and shifted up 1 unit
How to interpret the transformations of the functions?The functions are given as:
f(x) = 3sin(x)+1
g(x) = 3sin(x/4)+2
Start by stretching the function f(x) horizontally by a scale factor of 4.
So, we have:
f'(x) = 3sin(x/4) + 1
Next, shift the function f'(x) upward by 1 unit.
So, we have:
f'(x) = 3sin(x/4) + 1 + 1
Evaluate the sum
f'(x) = 3sin(x/4) + 2
Rewrite as:
g(x) = 3sin(x/4) + 2
Hence, the effect of transforming the function is (b) The graph is stretched horizontally by a factor of 4 and shifted up 1 unit

Surface area of sphere:
[tex]4\pi \times r {}^{2} [/tex]
Circumference :
[tex]2(\pi \times r)[/tex]
489.84 = 2 × 3.14 × r

Which is the inverse of the function f(x) = 4x − 9?
Step-by-step explanation:
x and y trade places.
f(x) = y = 4x - 9
y + 9 = 4x
x = (y + 9)/4
and to make it a true function notation, we need to rename x to y and vice versa and get
y = (x + 9)/4
