TV = 20^2 - 12^2 = 256 = 16
substitute:
16 / 4x + 3 = 12 / 9
16 / 4x + 3 = 4 / 3
cross multiply:
48 = 16x + 12
36 = 16x
2.25 = x
Answer:
x=3
Step-by-step explanation:
What u should always do is look at the letters of the triangles given:
It will tell u that:
\( \frac{tu}{dc} = \frac{uv}{cb} \)
Now we once again just sub in the values:
\( \frac{12}{9} = \frac{20}{4x + 3} \)
we can simplify the fraction on the right
\( \frac{4}{3} = \frac{20}{4x + 3} \)
And now we cross multiply
3×20=4(4x+3)
60=16x+12
60-12=16x
48=16x
Therefore :
x=3

find the sum
-84 + (-11)
Answers
Answer:
-84+(-11)= -95
-84 + (-11) = -84 - 11 = -95
By the commutative property, adding a negative number is the same as subtracting that number as a positive; therefore, something + (-11) = something - 11. After changing the equation from -84 + (-11) to -84 - 11, we use regular addition properties, adding the tens place and ones place to get -95.

Step-by-step explanation:
the sum of the 3 angles in a triangle = 180° , that is
x + 54° + 95° = 180°
x + 149° = 180° ( subtract 149° from both sides )

QUICK ANSWER NOW!!3. A researcher wants to evaluate the average income of US students one year after graduating from college.
a. If the researcher had taken 500 samples of 50 students who graduated a year ago from around the US and recorded their mean income, would a distribution of his results be considered a sampling distribution?
b. If the researcher obtained a sample of 500 UT students who graduated a year ago, would a distribution of their income results be considered a sampling distribution?
c. Which distribution would more accurately help you determine the mean income of all US students one year after graduating? Why is it more accurate?
Answers
Answer:
Follows are the solution to this question:
Step-by-step explanation:
The answer to Option a, It is a survey because it comes from across the United States and has greater population characteristics. Although In option B, it is the process of the distribution, which is not sampling because that is very UT-oriented. In option C, It specifies at the point (a), which simply is good because it is such a better population-representative and far less inclined.The Power in a circuit is given by the formula P=I^{2}R, where I is the Current and R is the Resistance. If the Resistance is always constant at 500, the Current is 1, and dI/dt = -0.5, then dP/dt = -500.
True or false and please show work. Thank you
Answers

Answer: m<ABC = 45 degrees, m<DBC = 36 degrees
Step-by-step explanation:
set both equations equal to 81 because they add up to form one angle:
5x + 6 + 9x - 9 = 81
Combine like terms
14x - 3 = 81
Add three to both sides
14x = 84
Divide by 14 to find x
x = 6
To find the angles:
Measurement of angle ABC:
9(6) - 9 = 45 degrees
Take the original angle of 81 and subtract the angle you just found to find the remaining angle:
81 - 45 = 36
Therefore, the angle of DBC is 36 degrees

Tamika has $800 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $482.62.
She buys 3 bicycle reflectors for $10.84 each and a pair of bike gloves for $24.49.
She plans to spend some or all of the money she has left to buy new biking outfits for $52.93 each.
Which inequality can be used to determine o, the maximum number of outfits Tamika can purchase while staying within her budget?
Answers
The inequality that can be used to determine x, the number of outfits Tamika can purchase is; 539.63+ 52.93x ≤ 800
The given parameters are:
Budget = $800
New bicycle = $482.62
3 bicycle reflectors = $10.84 each
Pair of a bike gloves = $24.49.
New biking outfits = $52.93each.
Let the number of new biking outfits be x So, we have;
New bicycle + 3 . price of bicycle reflectors + Pair of a bike gloves + New biking outfits <= Budget
This gives;
482.62 + 3( 10.84) + 24.49+ 52.93x ≤ 800
This gives;
539.63+ 52.93x ≤ 800
Solve the inequality;
52.93x ≤ 260.37
Divide by 52.93
x ≤ 4.91
Hence, the inequality is 539.63+ 52.93x ≤ 800

Consider the case where Apple computer tracks online transactions at its iStore and is interested in learning about the purchase patterns of its customers in order to provide recommendations as a customer browses its Web site. A sample of the shopping cart data in binary matrix format resides in the file AppleCart. Each row indicates which iPad features and accessories a customer selected. Using a minimum support of 10 percent of the total number of transactions and a minimum confidence of 50 percent, use XLMiner to generate a list of association rules.
a. Interpret what the rule with the largest lift ratio is saying about the relationship between the antecedent item set and consequent item set.
b. Interpret the support count of the item set involved in the rule with the largest lift ratio.
c. Interpret the confidence of the rule with the largest lift ratio.

Answers
Answer:
Hello attached below is the sample of the shopping cart data in binary matrix format resides in the file AppleCart
answer :
a) Antecedent : Retina display, stand; Consequent : speakers
b) The support count of that item set which is convoluted in the rule having the largest life ratio = 204 from the output of the " list of Rules "
c) 62.77%
d) The lift ratio = 2.27
e) The top 15 rules have features that are common and this makes apple to put interest on the assortments. as seen an iPad with a retina is always purchased with other accessories, Also an iPad with retina is always paired with memory upgrade as well.
Step-by-step explanation:
steps:
i) generate a list of association rules
ii) update the minimum support to 200 and the required minimum confidence to 50% ( on the dialog box )
a) using the output of the list of association rules
The rule expression for the largest life ratio can be written as
Antecedent : Retina display, stand; Consequent : speakers
This means that if an iPad with retina display is acquired with stand then the speakers are also acquired ( Rule with largest lift ratio )
b) Interpret the support count of the item set involved in the rule with the largest lift ratio
The support count of that item set which is convoluted in the rule having the largest life ratio = 204 from the output of the " list of Rules "
i.e. all items ( 3 ) purchased where purchased 204 times \
c) Interpret the confidence of the rule with the largest lift ratio.
confidence of the rule with the largest lift ratio can be interpreted as
= 204 / 325 = 62.77% i.e. speakers where acquired 204 out of 325 times of acquiring the retina display and stand together
d) Interpret the lift ratio of the rule with the largest lift ratio.
The lift ratio = 2.27
this means that a customer that has acquired a retina display, and a stand is 127% more prospective than other customers who purchase speakers
e) Review the top 15 rules,
The top 15 rules have features that are common and this makes apple to put interest on the assortments. as seen an iPad with a retina is always purchased with other accessories, Also an iPad with retina is always paired with memory upgrade as well.

Solution:
Given that the initial population was 6 million, and the population increased by 9.5% since 2000, this implies that
\(Percentage\text{ increase=}\frac{new\text{ population -inital population}}{initial\text{ population}}\times100\)Let x represent the new population.
By substitution, we have
\(\begin{gathered} 9.5=\frac{x-6000000}{6000000}\times100 \\ \Rightarrow9.5=\frac{x-6000000}{60000} \\ solving\text{ for x, we have} \\ x=6570000 \end{gathered}\)Hence, the new population is 6570000

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 4
and DC = 9, what is the length of BD? (Note: the figure is not drawn to scale.)
Answers
Answer:
BD = 6
Step-by-step explanation:
Theorem: The altitude to the hypotenuse of a right triangle is the mean proportional between the segments of the hypotenuse.
So, \(\frac{4}{BD} = \frac{BD}{9}\)
\(BD^{2} = 36\)
BD = 6
See how easy that is IF you know the theorem.
