Answer:
13=u
Step-by-step explanation:
54/4 = 13
Simplify the expression: 4(–1 − 6n)
Look at the triangle.
What is the value of sin x°?
(A) 5 ÷ 13
(B) 12 ÷ 5
(C) 12 ÷ 13
(D) 5 ÷ 12
Answer:
Ok, Sir, The answer is D.
Step-by-step explanation:
From the list of possible answers, the sides are 5 and 12 and the hypotenuse is 13, so sin(x) is either 5/13 or 12/13 depending on which of the two legs is opposite to angle x.
Determine whether each identity is true or false.

(a + b) (a + b) = a² + 2ab + b^2
(a + b) (a - b) = a² + 2ab – 6^2
(a + b) (a - b) = a² – 6^2
(a + b) (a + b) = a² + 6^2
(a - b) (a - b) = a² – 6^2
(a - b) (a - b) = a² – 2ab + b^2

Salvador wrote 15 letters to friends each month for p months in a row. Write an expression to show how many total letters Salvador wrote
Answer:
15p
Step-by-step explanation:
Let's interpret the question bit by bit
Salvador wrote 15 letters to friends each month
=> 15 letters = 1 month
For p months in a row
let the total number of letters for p months be x
=> x letters = p months
Bringing the two statements together gives;
15 letters = 1 month
x letters = p months
Now, let's solve for x by cross-multiplying the above
x letters * 1 month = 15 letters * p months
x = [tex]\frac{15 letters * p months}{1 month}[/tex]
x = 15p letters
Therefore, Salvador wrote a total of 15p letters for the p months.
1000 households were surveyed. 275 households own a desktop computer, 455 households own a DVD player, 405 households own two cars, 145 households own a desktop computer and DVD player, 195 households own a DVD player and two cars, 110 households own two cars and a desktop computer, 265 households do not own a desktop computer, do not own a DVD player, do not own two cars. Find the number of households that own: a) a desktop computer, DVD player and two cars; b) only a DVD player, no computer and no two cars; c) a desktop computer and DVD player but do not own two cars.
Answer:
Step-by-step explanation:
From the given information,
Suppose
X represents the Desktop computer
Y represents the DVD Player
Z represents the Two Cars
Given that:
n(X)=275
n(Y)=455
n(Z)=405
n(XUY)=145
n(YUZ)=195
n(XUZ)=110
n((XUYUZ))=265
n(X ∩ Y ∩ Z) = 1000-265
n(X ∩ Y ∩ Z) = 735
n(X ∪ Y) = n(X)+n(Y)−n(X ∩ Y)
145 = 275+455 - n(X ∩ Y)
n(X ∩ Y) = 585
n(Y ∪ Z) = n(Y) + n(Z) − n(Y ∩ Z)
195 = 455+405-n(Y ∩ Z)
n(Y ∩ Z) = 665
n(X ∪ Z) = n(X) + n(Z) − n(X ∩ Z)
110 = 275+405-n(X ∩ Z)
n(X ∩ Z) = 570
a. n(X ∪ Y ∪ Z) = n(X) + n(Y) + n(Z) − n(X ∩ Y) − n(Y ∩ Z) − n(X ∩ Z) + n(X ∩ Y ∩ Z)
n(X ∪ Y ∪ Z) = 275+455+405-585-665-570+735
n(X ∪ Y ∪ Z) = 50
c. n(X ∪ Y ∪ C') = n(X ∪ Y)-n(X ∪ Y ∪ Z)
n(X ∪ Y ∪ C') = 145-50
n(X ∪ Y ∪ C') = 95

Between 1896—when the Dow Jones index was created— and 2012, the index rose in 65% of the years. Based on this information, and assuming a binomial distribution, what do you think is the probability that the stock market will rise a) next year? b) the year after next? c) in four of the next five years? d) in none of the next five years? e) For this situation (modeling Dow Jones index), what assumption of the binomial distribution might not be valid? Are the years independent?
Answer:
a) P(x) = 0.67
b) P(y) = 0.67
c) P(x=4) = 0.3325
d) P( x = 0 ) = 0.0039
e) The fact that the rise and fall of the stock market relies on market sentiments violates independence used in Binomial distribution and the years are independent
Step-by-step explanation:
A) The probability that the stock market will rise next year = P(x) = 0.67
assuming next year to be X
B) Probability that the stock market will rise the year after next year
= P(y) = 0.67 and this is because the probability is independent of that of the previous years
C) Probability that the stock market will rise in four of the next five years
= P(x=4) = 0.3325
D) probability that the stock market will rise in none of the next five years
= P( x = 0 ) = 0.0039
E) The fact that the rise and fall of the stock market relies on market sentiments violates independence used in Binomial distribution and the years are independent
The probability that the stock market will rise next year = P(x) = 0.65.
The probability that the stock market will rise the year after next is p(y) = 0.65.
The probability that the stock market will rise in four of the next five years is 0.00325.
The probability that the stock market will rise in none of the next five years is 0.0039.
Independent events and probability can be defined as those occurrences that are not dependent on any specific event.

If h(x) = 2x - 1 and g(x) = 3x + 1, what is (h o g)(2)?
Answer:
Step-by-step explanation:
g(2) = 3(2) + 1 = 6 + 1 = 7
h(7) = 2(7) - 1 = 14 - 1 = 13
Using composite functions, it is found that:
[tex](h \circ g)(2) = 13[/tex]
The composition of functions h(x) and g(x) is given by:
[tex](h \circ g)(x) = h(g(x))[/tex]
In this problem, the functions are:
[tex]h(x) = 2x - 1[/tex]
[tex]g(x) = 3x + 1[/tex]
Then:
[tex]h(g(x)) = h(3x + 1) = 2(3x + 1) - 1 = 6x + 2 - 1 = 6x + 1[/tex]
At x = 2:
[tex](h \circ g)(2) = 6(2) + 1 = 13[/tex]

Answer:
the 3rd graph
Step-by-step explanation:
hope this helps! got it right edge 2021
Here we have a problem with translations, where translations are operators that act on functions and move the whole graph of the function in some given direction.
Sadly, the options for this question are missing, so I will answer in a general way and will post a graph at the end of the answer.
We should start by defining the translation used here.
Horizontal translation:
For a general function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left.If N is negative, the translation is to the right.Here we have that the original function is f(x) = |x|, and the translated function is g(x) = |x + 2|
Then we have:
g(x) = f(x + 2).
We can conclude that this is a translation of 2 units to the left.

The average age would increase. C. The average age would not change. D. The average age would decrease.
Answer:
b
Step-by-step explanation:
The average age would not change.
What is an outlier?An observation that lies an abnormal distance from other values in a random sample from a population.
What is a average?The average is the middle value of a set of numbers. It is calculated by adding the individual terms and dividing the sum with number of terms.
Outliers are stragglers — extremely high or extremely low values — in a data set that can throw off your stats.
Thus it does not effect the average age

Use Gauss's approach to find the following sum (do not use formulas):5+11+17+23...+83
Denote the sum by S. So
S = 5 + 11 + 17 + 23 + ... + 83
There's a constant difference of 6 between consecutive terms in S, so the 3 terms before 83 are 77, 71, and 65. So
S = 5 + 11 + 17 + 23 + ... + 65 + 71 + 77 + 83
Gauss's approach involves inverting the sum:
S = 83 + 77 + 71 + 65 + ... + 23 + 17 + 11 + 5
If we add terms in the same position in the sums, we get
2S = (5 + 83) + (11 + 77) + ... + (77 + 11) + (83 + 5)
and we notice that each grouped term on the right gives a total of 88. So the right side consists of several copies n of 88, which means
2S = 88n
and dividing both sides by 2 gives
S = 44n
Now it's a matter of determining how many copies get added. The terms in the sum form an arithmetic progression that follows the pattern
11 = 5 + 6
17 = 5 + 2*6
23 = 5 + 3*6
and so on, up to
83 = 5 + 13*6
so n = 13, which means the sum is S = 44*13 = 572.
Solve for the given variable. List the step used to solve the equation. 49.75 + 4.99x = 9.99x + 19.75?
Answer:
x=-2
Step-by-step explanation:
9.75+4.99x=9.99x+19.75
Simply Both Sides(change the order of 9.75 and 4.99x in this case)
4.99x+9.75=9.99x+19.75
Subtract 9.99x from both sides
4.99x+9.75−9.99x=9.99x+19.75−9.99x
−5x+9.75=19.75
Subtract 9.75 from both sides now
−5x+9.75−9.75=19.75−9.75
−5x=10
Divide both sides by -5 and boom
