Answer:
Step-by-step explanation:
a) 12 - n
1st term = 12 - 1 = 11
2nd term = 12 - 2 = 10
3rd term = 12- 3 = 9
4th term = 12 - 4 = 8
10th term = 12 - 10 = 2
b) 5 - 2n
1st term = 5 - 2*1 = 5 - 2 = 3
2nd term = 5 - 2*2 = 5 - 4 = 1
3rd term = 5 - 2*3 = 5 - 6 = -1
4th term = 5 - 2*4 = 5 - 8 = - 3
10th term = 5 - 2*10 = 5 - 20 = -15

Segment AX and Segment EX are secant segments that intersect at point X. What is the length of ED? a. 1 b. 3 c. 6 d. 9
Answer:
B. 3
Step-by-step explanation:
We can use secant theorem.
AX × BX = EX × DX
AX = 7 + 2 = 9
9 × 2 = (3 + x) × 3
18 = 9 + 3x
18 - 9 = 3x
9 = 3x
x = 9/3 = 3
The length of ED is 3 units.
Answer: B. 3 units
Good luck!
PLEASE HELP, AND PLAESE EXPLAIN!!!
Answer:
D. 22.5 sq. un.
Step-by-step explanation:
W divides BU so that there is a ratio of 1;2 meaning that there are 3 parts.
That means that 3 parts is BUV; we know that one of those parts is 4.5 sq. un. so 4.5*3=13.5 sq. un. - Also 4.5*2=9 to get WUV
V is the midpoint of the line BS so that means that BUV and UVS are equal
we know that BUV is 13.5 so we multiply that by 2 to get the whole triangle
=27
The last step is to get rid of BVW which we know is 4.5
27-4.5=22.5

In a regression analysis with multiple independent variables, multicollinearity can be caused by: A strong nonlinear relationship between the dependent variable and one or more independent variables A strong heteroskedastic relationship between the dependent variable and one or more independent variable A strong linear relationship between two or more independent variables None of the above
Answer:
A strong linear relationship between two or more independent variables
Step-by-step explanation:
Multicolinearity underestimates the statistical significance of the independent variables. It exists when an independent variable is highly correlated with one or many other independent variables giving rise to a large standard error.
Which of the following is a perfect square trinomial ? PLEASE HELP!!!!!!!!!!!!!!!!!
Answer:
The answer is C. 16x² - 56xy + 49y²
Step-by-step explanation:
A perfect square trinomial is the result of a squared binomial, the perfect square trinomial would be a² + 2ab + b², as that is what you get when you expand the brackets.
what can you say about the y-values of the two functions f(x) =3x^2-3 and g(x)=2^x-3
Answer:
The answers are A and C. for A P E X.
Step-by-step explanation:
The option(A) minimum y-value of g(x) approches -3 and option(C) f(x) has the smallest possible y-value are correct.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = 3x^2-3[/tex]
As we can see in the graph the first term is 3x² and is always positive for all x.
The range for f(x) ∈ [-3, ∞)
When x = 0
f(x) = -3
The above value is the smallest possible value on the y-axis.
For function:
[tex]\rm g(x) = 2^x-3[/tex]
[tex]\rm 2^x[/tex] is also a positive quantity and it is an exponential function.
The range for the g(x) ∈ (-3, ∞)
It means g(x) never toches the y-axis at -3.
We can say the minimum value of g(x) approaches -3
Thus, the option(A) minimum y-value of g(x) approches -3 and option(C) f(x) has the smallest possible y-value are correct.

y = a( x-h)^2 + k
where ( h,k) is the vertex and x=h is the axis of symmetry
( 5,-7) is the vertex and x=5 is the axis of symmetry
Given right triangle XYZ, what is the value of sin(Y)? (Hint: Special Right)
A.) 1/2
B.) SqRt3/3
C.) SqRt3/2
D.) (2SqRt3)/3
Answer:
sinY = 2
or
x = 2
Step-by-step explanation:
None of the above answer choices are correct. If you solve for sinY:
sin30° = x/4
4sin30° = x
x = 2
Now that we have x, we use our special right triangle rules for 30-60-90 triangles. The angle across the 30° is x, the angle across the 60° is x√3 and our hypotenuse is 2x. Our answer would still be x = 2, so none of the answer choices are correct.

The scale on a map indicates that 1 inch represents 10 miles. If two cities are 2 3 4 inches apart on a map, how many miles apart are the two cities?
Answer:
Step-by-step explanation:
2340 miles
Given
1 inch represents 10 miles
thus,
1 inch on map = 10 miles in real
given the two cities are 234 inches apart on map
1 inch on map = 10 miles in real
multiplying both side by 234
1 inch*234 on map = 10 miles*234 in real
234 inch on map = 2340 miles in real.
Thus, two cities are 2340 miles apart.
Answer:
27.5 miles
Step-by-step explanation:
You need to multiply 2 3/4 by 10, because it says every inch represents 10 miles.
2 3/4 * 10
11/4 * 10/1 = 55/2
27 1/2 or, 27.5
If h(x) = 5 + x and f(x) = 5, which expression is equivalent to (kn)(x)?
Answer:
Step-by-step explanation:
The question is not correctly written, here is the correct question.
If h(x) = 5 + x and k(x) = 5, which expression is equivalent to (koh)(x)?
(koh)(x) can be rewritten as k{h(x)}
Since h(x) = 5+x then, k{h(x)} = k(5+x)
Note that k(x) can be written as 5x°
k(5+x) = 5(5+x)°
Since any value raise to the power of zero is 1, then;
k(5+x) = 5(1)
k(5+x) = 5
(koh)(x) = k{h(x)} = 5
For (hok)x;
(hok)x = h{k(x)}
= h(5)
= h(5x°)
Since h(x) = 5+x
h(5x°) = 5+5x°
h(5x°)= 5+5 = 10
(hok)x = h(k(x)) = 10
which graph represents the hyperbola x2/32-y2/82=1?
Answer:
Step-by-step explanation:
You have the following hyperbola:
[tex]\frac{x^2}{32}-\frac{y^2}{82}=1[/tex] (1)
The general for of a hyperbola:
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]
To construct the graph you take into account the rectangle formed by the lines x=±a and y=±b, and the asymptotes of the diagonals of the rectangles.
Furthermore, you take into account the foci of the hyperbola, which are
(0,±a).
Then, you have the lines
x = ± √32
y = ± √82
And the foci:
(0, ± √32)

Step-by-step explanation:
Kevin is an auto mechanic. He spends 2 hours when he replaces the shocks on a car and 2 hours when he replaces the brakes. He works no more than 54 hours a week. He routinely completes at least 4 shocks replacements and 6 brake replacements a week. If he charges $450 for labor replacing shocks and $200 in labor for replacing brakes, how many jobs of each type should he complete a week to maximize his income? Kevin should do shock replacements and ? brake replacements every week to maximize his weekly income
Answer:
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
Step-by-step explanation:
Since either job takes 2 hours to complete, the total number of jobs that Kevin can complete working 54 hours a week is:
[tex]n=\frac{54}{2}\\n=27\ jobs[/tex]
Since replacing shocks gives him a greater income, he should aim to do as little break replacements as possible and as many shock replacements as possible in order to maximize income.
If he has to complete at least 6 break replacements out of the 27 jobs possible, the number of shock replacements he should do is:
[tex]S=27-6\\S=21[/tex]
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
Q3. Samir spins a fair coin and records the results. In the first four spins ‘Heads' comes up each time. Samir says, ‘A head is more likely than a tail'. Is he correct? YES/ NO Give a reason for your answer.
Answer:
The conclusion drawn by Samir is Not correct.
Step-by-step explanation:
The spinning of a fair coin is a Bernoulli experiment.
There are only two outcomes: Heads (H) or Tails (T).
Theoretically, each of the two outcomes has an equal probability of occurrence i.e. P (H) = P (T) = 0.50.
Now, suppose an experiment is conducted to test this theory.
The law of large numbers, in probability concept, states that as the number of times an experiment is conducted, say n, in increased, the average value of the experiment approaches the expected value.
To determine whether ‘A head is more likely than a tail', the experiment of spinning the coin must be repeated more than n = 4 times.
In statistics, n = 30 is considered as a large enough sample.
So, the conclusion drawn by Samir is Not correct.

factorize xsquare-25
Answer:
The answer is (x + 5)(x - 5).
Step-by-step explanation:
Assuming that 25 is a perfect square so you can apply :
[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
Test :
[tex](x+5)(x-5) = {x}^{2} - 5x + 5x - 25 [/tex]
[tex](x+5)(x-5) = {x}^{2} - 25 [/tex]
Answer:
[tex]\boxed{(x-5)(x+5)}[/tex]
Step-by-step explanation:
x² - 25
Factor out square.
(x)² - (5)²
Apply difference of two squares formula.
a² - b² = (a-b)(a+b)
a = x
b = 5
x² - 25 = (x-5)(x+5)
