What is the answer?
2(x + 3) = x - 4
Answer:
-10
Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
take out the parantheses
2x + 6 = x - 4
Put the variable on the left side of the ecuation with the opposite sign
2x + 6 -x = -4
Put the six on the right side of the equation and change the sign
2x - x = - 4 - 6
simplify
x = - 4 - 6
x = -10

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

Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1?
9.6, –4.8, 2.4, –1.2, 0.6, ...
f(n + 1) = (–0.5)f(n)
f(n + 1) = (0.5)f(n)
f(n + 1) = f(0.5n)
f(n + 1) = f(–0.5n)
Answer:
f(n + 1) = (–0.5)f(n)

A spinner has an equal chance of landing on either red blue or green. You spin six times. What is the probability that spinner lands on red at least two times?
Answer:
0.8906 ( 4 decimal places)
Step-by-step explanation:
With an equal probability of landing in either blue or red, then
Probability of success, p = 0.5
Number of trials, n = 6
Probability of landing on red atleast twice Can be obtained using a cumulative binomial probability ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x ≥ 2) = p(x = 2) + p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6)
Obtaining the individual probabilities and summing them up or we could use a cumulative probability option on either a calculator, excel or an online binomial probability distribution.
Using an online binomial probability calculator :
P(x ≥ 2) = 0.890625
P(x ≥ 2) = 0.8906 ( 4 decimal places)

Answer:
right triangle
Step-by-step explanation:
To test for a right triangle, use the Pythagorean theorem.
Let the legs, a and b, be the two shorter sides, and let the hypotenuse, c, be the longest side.
a² + b² = c²
a² + b² = 7.2² + 9.6² = 51.84 + 92.16 = 144
c² = 12² = 144
Since a² + b² = c², the triangle is a right triangle.

The formula for finding the volume of a cube is V=s3, where s is the length of one side. What is the volume, in cubic units, of a cube with side length 7.5 units? Round to the nearest hundredth when necessary
Answer:
421.88 cubic units
Step-by-step explanation:
The formula for finding the volume of a cube is V=s3, where s is the length of one side. What is the volume, in cubic units, of a cube with side length 7.5 units? Round to the nearest hundredth when necessary
V =s³
s = 7.5 units
V = (7.5 units)³
V = 421.875 cubic units
Approximately = 421.88 cubic units

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

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
Hence, the true statements are: options 2, 3 and 4.
