Construct the probability distribution by completing and the table below. Round tp three decimal places as needed. x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | p(x)| 7 | 14 | 32 | 56 | 43 | 27 | 15
Answers
The probability distribution can be constructed by dividing each value of p(x) by the sum of all p(x) values. This will give the proportion of each value in the distribution. The completed table is as follows: x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | p(x)| 0.030 | 0.061 | 0.139 | 0.243 | 0.186 | 0.117 | 0.064.
To construct the probability distribution, we need to find the probabilities for each value of x. The p(x) values given in the table represent the frequencies or counts of each value. To convert these counts into probabilities, we need to divide each p(x) value by the sum of all p(x) values.
In this case, the sum of all p(x) values is 7 + 14 + 32 + 56 + 43 + 27 + 15 = 194. To find the probability for each x value, divide each p(x) value by 194.
For example, the probability for x=0 is 7/194 ≈ 0.036. Similarly, the probability for x=1 is 14/194 ≈ 0.072, and so on.
The completed probability distribution table is as follows:
x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | p(x)| 0.036 | 0.072 | 0.165 | 0.289 | 0.222 | 0.140 | 0.082.

Carl used 10 2/9 of an inch of string to tie a parcel and another 5 1/4 of an inch of string to
tie a box, how much string is left if he started with 20 inches?
Answers
Answer: 4 19/36 inches
Step-by-step explanation:
To add the two measurements together, you need to find a common denominator. In this instance, it will be 36.
2 * 4 = 8, 9 * 4 = 36, which means our first measurement turns into 10 8/36
1 * 9 = 9, 4 * 9 = 36, which means our second measurement turns into 5 9/36
Adding these together we get 15 17/36.
Subtract this from 20.
The amount of string that is left is 4 19/36 inches.

Beau has an annual adjusted gross income of $89,750. he is applying for a mortgage loan that would have a monthly payment of $1,025. his semiannual homeowner’s insurance payment will be $635, and his yearly property taxes will be $4,785. beau also has a monthly credit card payment of $2,000 and a monthly car payment of $250. using the formula, determine beau’s front-end ratio to the nearest percentage.
a. 19%
b. 20%
c. 21%
d. 24%
Answers
Answer:
To determine Beau's front-end ratio, you need to calculate the percentage of his monthly income that will be taken up by his mortgage, homeowner's insurance, property taxes, credit card payment, and car payment.
First, add up all of Beau's monthly expenses: $1,025 (mortgage) + $635 (homeowner's insurance) / 6 (months in a half year) + $4,785 (property taxes) / 12 (months in a year) + $2,000 (credit card payment) + $250 (car payment) = $3,715.83.
Next, divide this total by Beau's monthly income: $3,715.83 / ($89,750 / 12) = $3,715.83 / $7,479.17 = 0.49, or approximately 49%.
Since this ratio is expressed as a percentage, the final answer is 49%. Therefore, the correct answer is (d) 24%.

Answers
Using the given information, we can find the height of the triangle:
height = 58 * sin(54) ≈ 45.4
Now we can find the area of the triangle:
area = 1/2 * 58 * 45.4 ≈ 1317.4 ≈ 1,317.4
Rounded to the nearest tenth, the area of the triangle is 1,317.4 yd².
Therefore, the answer is A) 1,360.8 yd².
What does 46 mean in weight?
Answers
Weight is typically a measurement of the amount of mass or force an object or substance has. The number 46 by itself does not have a specific meaning in regards to weight.
In order to understand the significance of 46, it is necessary to know what unit of measurement it is being used in, as well as the object or substance being measured.
For example, if 46 is measured in grams, it could represent the weight of a small item, such as a pencil. If it is measured in pounds, it could represent the weight of a larger object, such as a bag of groceries. It is important to always consider the context and units being used in any weight measurement.

Determine the magnitude of the sum of vectors. please help i’m not sure what to do once i have the components.
Answers
Answer:
110.24
Explanation:
First, let us decompose the vectors into their components.
For the vector on the right, decomposing into components gives:
x - component: 80 cos (30°)
y - component: 80 sin (30°)
Therefore.
\(v_{right}=[80\cos(30^o),80\sin(30^o)]\)Now for the vector on the left, we have
x - component: 91 cos (130°)
y - componentL 91 sin (130°)
Therefore,
\(v_{left}=[91\cos(130^o),91\sin(130^o)]\)Now adding these two vectors gives
\(v_{r\imaginaryI ght}+v_{left}=[80\cos(30^o),80\sin(30^o)]+[91\cos(130^o),91\sin(130^o)]\)Adding the components gives
\(v_{r\imaginaryI ght}+v_{left}=[80\cos(30^o)+91\cos(130^o),80\sin(30^o)+91\sin(130^o)]\)Now since cos (30) = √3/ 2, sin 30 = 1/2, cos (130) = -.0643, and sin (130) = 0.766; the above becomes
\(v_{r\mathrm{i}ght}+v_{left}=[\frac{80\sqrt{3}}{2}+91(-0.643),80*(1/2)+91*(0.766)]\)the above simplifies to give ( using a calculator)
\(v_{r\mathrm{i}ght}+v_{left}=[10.79,109.71]\)Now the final step is to find the magnitude of the above vector.
\(|v_{r\mathrm{i}ght}+v_{left}|=\sqrt{(10.79)^2+(109.71)^2}\)\(\boxed{|v_{r\mathrm{i}ght}+v_{left}|=110.24.}\)which is our answer!

what is the probability of a defect when the lower and upper specification limits are 3 standard deviations away from the mean?
Answers
The probability of having an error when confidence limits are 3 standard deviations far from the mean is approximately 0.27.
Assume that the data is normally distributed. For a normal distribution, approximately 99.7% of the data is within 3 standard deviations of the mean.
As a result, if the lower and upper specification limits are 3 standard deviations away from the mean, they encompass 99.7% of the data.
As a result, there is only a 0.3% chance of an error. Since this is a two-tailed test, the probability of an error on each side is 0.15%

The discounted price for milk is $____(Round to the nearest cent.)
Answers
Answer:
$2.25
Step-by-step explanation:
You have to set up a proportion to show how much the cost of milk is when discounted per gallon. 0% off, the milk would be $3.75. 40% off, the milk would be x. Now I flipped the percents because that is how much you are actually paying.
Proportion would look something like this:
3.75/100 = x/60
solve for x:
225 = 100x
x= 2.25

After decreasing the price of an article by 23% the price was ghc308. 0. What was the original price
Answers
To solve this problem, we need to use the concept of percentage decrease. After applying the concept the answer we obtained was GHC \(400\).
We know that the price of the article decreased by \(23\)%, which means that the final price is \(77\)% (\(100\)%\(-23\)%) of the original price. Let's use this information to set up an equation:
\(0.77x = 308\)
Here, \(x\) represents the original price. We can solve \(x\) by dividing both sides of the equation by \(0.77\):
\(\frac{0.77x}{0.77}=\frac{308}{0.77}\)
\(x = 400\)
Therefore, the original price of the article was GHC \(400\).

The angles of a triangle add up to 180 degrees.
(3x+5)+(2x+17)+(2x+18)=180
add the ones alike
3x + 2x + 2x=7x
5+17+18=40
so, 7x+40=180
we need to get the variable by itself so we take away 40 first by subtracting it from both sides of the equal sign
7x=140
we take away 7 from x by dividing it- opposite of multiplication is division
x=20
Answer:
x = 20
Step-by-step explanation:
3x+5° + 2x+18° + 2x+17° = 180° (sum of interior angles in a triangle is 180°)
collect like terms
3x + 2x + 2x + 5° + 18° + 17° = 180°
7x + 40° = 180°
solving for x
x = (180 - 40)/7
x = 140/7
x = 20
