what is 1/3(w+18)=12 using distributive property?
Answer:
w = 18
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (w + 18) = 12 ← distribute parenthesis on left side
[tex]\frac{1}{3}[/tex] w + 6 = 12 ( subtract 6 from both sides )
[tex]\frac{1}{3}[/tex] w = 6 ( multiply both sides by 3 to clear the fraction )
w = 18

You receive an A 40% of the time, a B 20% of the time, a C 15% of the time , and a D the rest of the time. For any random test, what is your expected grade point average? (Use the following values for X: A=4, B=3, C=2, D=1)
The grade you receive on a test is a discrete random variable with probability mass function
[tex]f_X(x)=P(X=x)=\begin{cases}0.4&\text{for }X=4\text{ (i.e. scoring an A)}\\0.2&\text{for }X=3\text{ (B)}\\0.15&\text{for }X=2\text{ (C)}\\0.25&\text{for }X=1\text{ (D)}\\0&\text{otherwise}\end{cases}[/tex]
where the probability of getting a D is 25% because there are only 4 possible grades, and the probabilities must sum to 1 :
0.4 + 0.2 + 0.15 + 0.25 = 1
The expected test score/GPA is then
[tex]\displaystyle\sum_x x\,f_X(x)=\sum_{x=1}^4 x\,P(X=x)=1\cdot0.25+2\cdot0.15+3\cdot0.2+4\cdot0.4=\boxed{2.75}[/tex]
so your average would fall between a B and a C.
A sphere has a surface area of 803.84 cm^2. What is the volume?
Answer:
V≈2143.03cm³
Step-by-step explanation:
The volume of the sphere is 2143.57 cm³.
What is the surface area of the sphere?A = 4 × π × r², where 'r' is the radius of the sphere.
What is the volume of the sphere?V = (4/3) × π × r³
For given example,
a surface area of the sphere is 803.84 cm^2.
⇒ A = 803.84 cm²
Using the formula of the surface area of the sphere,
⇒ 4πr² = 803.84
⇒ r² = 64
⇒ r = 8 cm
Using the formula of the volume of the sphere,
⇒ V = (4/3) × π × r³
⇒ V = (4/3) × 3.14 × 8³
⇒ V = 2143.57 cm³
Therefore, the volume of the sphere is 2143.57 cm³.

The sixth grade art students are making a mosaic using tiles in shapes of right triangles. Each tiles has the leg measures of 5.2 cm and 6 cm. If there are 150 tiles in the mosaic, what is the area of the mosaic?
Given:
Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.
There are 150 tiles in the mosaic.
To find:
The area of the mosaic.
Solution:
We know that, the area of a triangle is:
[tex]A=\dfrac{1}{2}\times Base\times height[/tex]
So, the area of Each right triangular tile is:
[tex]A=\dfrac{1}{2}\times 5.2\times 6[/tex]
[tex]A=\dfrac{1}{2}\times 31.2[/tex]
[tex]A=15.6[/tex]
There are 150 tiles in the mosaic. So, the area of the mosaic is:

Which transformations are needed to change the parent cosine function to y = 3 cosine (10 (x minus pi))?
Answer:
See Explanation
Step-by-step explanation:
Given
New function: [tex]y = 3 \cos(10 (x -\pi))[/tex]
We can assume the parent function to be:
[tex]y = \cos (x)[/tex]
The new function can be represented as:
[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex]
Where
A = Vertical stretch factor
B = Period
C = Right shift
By comparison:
[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex] to [tex]y = 3 \cos(10 (x -\pi))[/tex]
[tex]A = 3[/tex]
[tex]c = \pi[/tex]
[tex]\frac{2\pi}{B} = 10[/tex]
Solve for B
[tex]B = \frac{2\pi}{10}[/tex]
[tex]B = \frac{\pi}{5}[/tex]
Using the calculated values of [tex]A,\ B\ and\ c.[/tex] This implies that, the following transformations occur on the parent function:

Jordan has a bag that contains orange chews, strawberry chews, and lime chews. He performs an experiment. Jordan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Jordan performs the experiment 61 times. The results are shown below: An orange chew was selected 11 times. A strawberry chew was selected 17 times. A lime chew was selected 33 times. Based on these results, express the probability that the next chew Jordan removes from the bag will be strawberry chew as a decimal to the nearest hundredth.
Answer:
17/61 or 0.27
Step-by-step explanation: 17 out of 61 times Jordan will pull out strawberry so the probability of pulling out a strawberry chew is 17/61 which is 0.27 as a decimal

Write the Equation of the line in fully simplified slope- intercept form
Answer:
y=-6/5x-2
Step-by-step explanation:
We are given points (5,-8) and (-5,4)
Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5
Y-intercept = b = (0,-2)
Final equation: y=-6/5x-2
Answer:
y=-6/5x-2
Step-by-step explanation:
y=mx+b
Its sloping downwards, so a negative slope.
two points: (-5,4) and (5,-8)
---------------------------------------------
so first find the slope.
y2-y1 / x2-x1 <= formula
so: -8-(4) / 5-(-5)
which becomes => -12/ 10
which is 6/5 the slope is 6/5
------------------------------------------
plug this into y=mx+b, where m is the slope
so: y=6/5x+b
------------------------------------------
obviously b is the y intercept, where the line meets y
the y intercept is -2
sooooooo final answer is
----------------------------------
y=6.5x+(-2)
-----------------------------------
Negative slope, so becomes y=6/5x-2
