Answer:
x = 2.66666667
Step-by-step explanation:
3(x + 1) = 11
We multiply both x and 1 by 3 and get
3x + 3 = 11
Now we subtract 3 from both sides
3x + 3 - 3 = 11 - 3
3x = 8
Now divide both sides by 3
3x/3 = 8/3
x = 2.66666667

Find the inverse of
g(x)=16+x/4
Give full explanation
Answer:
x/4 + 16
Step-by-step explanation:
to add or subtract the expressions expand them to make therir deomanators the same . Multiply 16 times 4/4
since 16 x 4/4 have the same deniomanator add them by adding the numorators
do the multiplications in 16X4 + x
= x/4 + 16

which expressions is equivalent to 4(2x+3y)
Answer: 8x+12y
Step-by-step explanation:
Assuming this is a problem in a unit on distributive property, and thus, due to the apparent lack of options, will solve it as such:
The distributive property dictates that a(b+c) = ab+ac.
Thus,
4(2x+3y)
8x+12y

Lina used 75 square inches of fabric to make a triangular pennant to take to football game.The base of the pennant was 6 inches. What was the height of the pennant?
Answer:
25 inches
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
75 = (1/2) x 6 x height
height = (75 x 2) / 6 = 25 inches
What is the midpoint of the segment shown below no links please
Answer:
D. (2,5)
Step-by-step explanation:
Since the segment is straight and horizontal the y-value will still be 5. Now to find the midpoint you simply figure out how long the segment is and divide by 2. After dividing by 2 you can add that number to smallest value or subtract it from the largest value to get the midpoint x value.
A cereal company is putting 1 of 4 prizes in each box of cereal. The prizes are evenly distributed so the
probability of winning any given prize is always 1/4.
Lily wonders how many boxes she should expect to buy to get all 4 prizes. She carried out 20 trials of a
simulation and her results are shown below. Each dot represents how many boxes it took to get all 4 prizes in
that trial.

P(fewer than 7 boxes) -
Answer:
[tex]P(x < 7) = 0.383[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Determine the probability that few than 7 boxes will be needed.
This is represented as:
[tex]P(x < 7)[/tex]
And the solution is:
[tex]P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)[/tex]
Each probability is calculated by dividing the number of dots by the total dots.
So, we have:
[tex]P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}[/tex]
From the attached, the formula becomes:
[tex]P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}[/tex]
[tex]P(x < 7) = \frac{13}{36}[/tex]
[tex]P(x < 7) = 0.361[/tex]

Add the following rational numbers: 5/8 and 3/-10
Answer:
= 13/40
Step-by-step explanation:
(5/8) + (3/-10)
5/8 = 50/80
3/-10 = -24/80
then:
(5/8) + (3/-10) = 50/80 - 24/80
= 26/80 = 13/40
Answer:
13/40
Step-by-step explanation:
Segment AB has endpoints A(-2, 8) and B(4,0). The segment is dilated about the origin by a scale factor of 0.5 to create segment AB
What are the endpoints of segment AB?
select both endpoints
(-2,8)
(-1,4)
(0,0)
(1,4)
(2,0)
(4,0)
[please help, i would appreciate it alot]
Answer:
Step-by-step explanation:
(-1,4) (1,4) 2,0
The endpoint of the line segment will be (-1, 4) and (2, 0). Then the correct options are B and E.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
Section Stomach muscle has endpoints A(- 2, 8) and B(4,0). The section is widened at the beginning by a scale variable of 0.5 to make a fragment of the Stomach muscle.
The endpoint of the line segment is given as,
A = 0.5(-2, 8)
A = (-1, 4)
B = 0.5(4, 0)
B = (2, 0)
The endpoint of the line fragment will be (- 1, 4) and (2, 0). Then the right choices are B and E.

A rock weighs 80 g on a triple beam scale. The same rock is then gently placed inside a graduated cylinder containing 30 mL of water. If the water level in the graduated cylinder rises to 75 mL. What is the density of the rock
Answer:
1.78 g/cm³Step-by-step explanation:
80 g rock displaces water:
75 ml - 30 ml = 45 ml = 45 cm³Density = mass / volume:
d = 80 g / 45 cm³d = 1.78 g/cm³ (rounded)Which function is the inverse of f(x) = 2x + 3

Macy rolls a fair eight sided die with sides numbered from 1 to 8. Then from a box, she draws a numbered slip of paper. The slips of paper have numbers shown below.
1,2,5,7,8
Finally, she calculates the sum of her results.
Select all the true statements.
1.)A sum equal to 8 is the result 20 times in 80 rounds. This suggests the game is unfair.
2.)The probability of getting a sum that is a multiple of 3 is 3/8
3.) The probability of getting a sum that is even is 1/2.
4.) The probability of getting a sum that is greater than or equal to 12 is 11/40.
5.) The probability of getting a sum that is less than 10 is 21/40
There can be multiple answers
Probabilities are used to determine the chances of an event. The true statements from the 5 options are:
Probability that multiple of 3 is [tex]\frac{3}{8}[/tex]Probability of even sum is [tex]\frac{1}{2}[/tex]Probability of a sum greater than or equal to 12 is [tex]\frac{11}{40}[/tex]Given that:
[tex]Die =\{1,2,3,4,5,6,7,8\}[/tex]
[tex]Number = \{1,2,5,7,8\}[/tex]
The possible outcomes are:[tex]S = \{(1,1),(1,2),(1,5),(1,7),(1,8),(2,1),(2,2),(2,5),(2,7),(2,8),(3,1),(3,2),(3,5),(3,7),(3,8)\\(4,1),(4,2),(4,5),(4,7),(4,8),(5,1),(5,2),(5,5),(5,7),(5,8),(6,1),(6,2),(6,5),(6,7),(6,8),\\(7,1),(7,2),(7,5),(7,7),(7,8),(8,1),(8,2),(8,5),(8,7),(8,8)\}[/tex]
The sum of the outcomes are:
[tex]S = \{2,3,6,8,9,3,4,7,9,10,4,5,8,10,11,5,6,9,11,12,6,7,10,12,\\13,7,8,11,13,14,8,9,12,14,15,9,10,13,15,16\}[/tex]
Rearrange
[tex]S = \{2,3,3,4,4,5,5,6,6,6,7,7,7,8,8,8,8,9,9,9,9,9,10,10,10,10,11,11,11,\\12,12,12,13,13,13,14,14,15,15,16\}[/tex]
[tex]n(S) = 40[/tex]
Next, we test the options
(1) The game is unfair
The question implies that the eight sided die is fair. This means that the game is fair.
Option (1) is false.
(2) Probability that multiple of 3 is [tex]\frac{3}{8}[/tex]
The multiples of 3 in the sample space are:
[tex]3's = \{3,3,6,6,6,9,9,9,9,9,12,12,12,15,15\}[/tex]
[tex]n(3's) =15[/tex]
The probability is then calculated as:
[tex]P(3's) = \frac{n(3's)}{n(S)}[/tex]
[tex]P(3's) = \frac{15}{40}[/tex]
Simplify
[tex]P(3's) = \frac{3}{8}[/tex]
Option (2) is true
(3) Probability of even sum is [tex]\frac{1}{2}[/tex]
The even outcomes are:
[tex]Even =\{2,4,4,6,6,6,8,8,8,8,10,10,10,10,12,12,12,14,14,16\}[/tex]
[tex]n(Even) = 20[/tex]
The probability is then calculated as:
[tex]P(Even)= \frac{n(Even)}{n(S)}[/tex]
[tex]P(Even)= \frac{20}{40}[/tex]
Simplify
[tex]P(Even)= \frac{1}{2}[/tex]
Option (3) is true
(4) Probability of a sum greater than or equal to 12 is [tex]\frac{11}{40}[/tex]
The outcomes of a sum greater than or equal to 12 are:
[tex]Sum \ge 12 = \{12,12,12,13,13,13,14,14,15,15,16\}[/tex]
[tex]n(Sum \ge 12) = 11[/tex]
The probability is then calculated as:
[tex]P(Sum \ge 12) =\frac{n(P(Sum \ge 12)}{n(S)}[/tex]
[tex]P(Sum \ge 12) =\frac{11}{40}[/tex]
Option (4) is true
(5) Probability of a sum less than 10 is [tex]\frac{21}{40}[/tex]
The outcomes of a sum less than 10 are:
[tex]Sum < 10 = \{2,3,3,4,4,5,5,6,6,6,7,7,7,8,8,8,8,9,9,9,9,9\}[/tex]
[tex]n(Sum < 10) = 22[/tex]
The probability is then calculated as:
[tex]P(Sum < 10) =\frac{n(P(Sum < 10)}{n(S)}[/tex]
[tex]P(Sum < 10) =\frac{22}{40}[/tex]
Option (5) is false

Find the volume of the solid. (FSSS!) Round answers to the nearest hundredth.
Answer:
x = 9.27 cm
Volume = 289.2 cm³
Step-by-step explanation:
SA = Surface Area
SA = 229.2 cm²
P = Perimeter of Base
P = 3(6)
P = 18 cm
H = Height of Solid
H = x
A = Area of Base(Equilateral Triangle)
A = 6²√3 / 4
A = 36√3 / 4
A = 9√3
A = 9(1.732)
A = 31.176
A = 31.2 cm²
SA = Surface Area
SA = PH + 2A
229.2 = 18x + 2(31.2)
229.2 = 18x + 62.4
229.2 - 62.4 = 18x
166.8 = 18x
9.266 = x
9.27 = x
x = 9.27 cm
V = Volume
V = AH
V = 31.2(9.27)
V = 289.224
V = 289.2 cm³

If the spinner shown is spun 40 times, predict the number of times the spinner would land on Section B.
Answer:
10 times
Step-by-step explanation:
Given that:
Number of sections = (A, B, C, D) = 4
Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes
P(landing on B) = 1 /4
Predicted Number of times spinner will land on D ; if spinner is spurned 40 times
1/4 * 40 = 10 times
