Considering that there are only two possible outcomes for each number, and a fixed number of numbers, the distribution is:
C. binomial.
What distribution models the situation?We have that:
For each number on the sequence, there are only two possible outcomes, either it is even or it is odd.A number being even is independent of any other number.The sequence has a constant cardinality.Hence the binomial distribution should be used and option B is correct.

Solve for x: -5(-3x+1)=-45
Answer:
x = -8/3
Step-by-step explanation:
-5(-3x+1)=-45
⇔ 15x - 5 = -45 (left side of the equation expanded)
⇔ 15x = -45 + 5 (add 5 to both sides)
⇔ 15x = -40
⇔ x = -40/15 (Divide both sides by 15)
⇔ x = -8/3 (simplify)

For a certain company, the cost for producing x items is 50x + 300 and the revenue for selling x items is 90x - 0.5x^2.
The profit that the company makes is how much it takes in (revenue) minus how much it spend (cost). In economic models, one typically assumes that a company wants to maximize its profit or at least wants to make a profit:
Set up an expression for the profit from producing and selling x items
Find two values of x that will create a profit of $300
Using the profit concept, we have that:
The expression is: P(x) = -0.5x² + 40x - 300.A profit of $300 is found with x = 20 and x = 60.What is the profit concept?Profit is given by revenue subtracted by costs.
In this problem, we have that:
The revenue is: R(x) = 90x - 0.5x².The costs are: C(x) = 50x + 300.Hence the expression for the profit is given as follows:
P(x) = R(x) - C(x)
P(x) = 90x - 0.5x² - 50x - 300
P(x) = -0.5x² + 40x - 300.
A profit of $300 is found when P(x) = 300, hence:
300 = -0.5x² + 40x - 300
0.5x² - 40x + 600 = 0.
x² - 80x + 1200 = 0.
(x - 60)(x - 20) = 0.
Hence the values are:
x - 60 = 0 -> x = 60.x - 20 = 0 -> x = 20.More can be learned about the profit concept at https://brainly.com/question/4001746

Simplify, using the distributive
property.
5f + 16f = (5 +?)f=?f
Applying the distributive property, we would simplify the expression as: 5f + 16f = (5 + 16)f = 21f.
How to Apply the Distributive Property?The distributive property states that, ab + ac = (b + c)a.

Dilate ∆ABC about the origin using the scale factor n. Measure and compare the lengths of the sides of the dilated triangle, ∆A'B'C', with those of ∆DEF. Take a screenshot of your dilation, save it, and insert the image below the table.
The attached graph represents the image of the triangles
How to dilate the triangle?To do this, we make use of the following coordinates
A = (1, 0)
B = (5, 0)
C = (1, 6)
The lengths of the triangle are calculated using
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]
So, we have:
[tex]AB = \sqrt{(1-5)^2 + (0 -0)^2} = 4[/tex]
[tex]BC = \sqrt{(1-5)^2 + (6 -0)^2} = 7.2[/tex]
[tex]AC = \sqrt{(1-1)^2 + (6 -0)^2} = 5[/tex]
Using the scale factor of 2, we have the image of the dilation to be:
D = (2, 0)
E = (10, 0)
F = (2, 12)
The lengths of these sides are

A block is a rectangle that measures 100yards by 76yards. How many times around the block do you have to drive in order to drive one mile?
If block has length 100 yards and breadth 76 yards then we have to drive 5 times to drive one mile.
Given The length of block is 100 yards, the breadth of block is 76 yards.
We have to find number of times we need to drive one mile.
The perimeter of a rectangle= 2(length +breadth)
length is 100 yards
Breadth is 76 yards
perimeter=2(100+76)
=2*176
=352 yards.
We know that 1 mile is equal to 1760 yards.
We have to find number of times to drive 1 mile=1760/352
=5 times.
Hence we have to drive 5 times around the block which have length 100 yards and breadth 76 yards.

First, let's complete the angles in the triangle. Remember that the sum of the angles in a triangle is 180 degrees.
73 + 90 + x = 180
163 + x = 180
x = 17
So, the angle that completes the triangle is 17 degrees. If we look at that angle in the triangle and the one adjacent to it, we can see that those two angles form a linear pair (or are supplementary, both meaning that they add up to 180 degrees).
17 + x = 180
x = 163
So, 17's supplement is 163 degrees. The 163 degree angle corresponds with angle r, and corresponding angles are congruent.
Therefore, angle r is 163 degrees. The correct answer is option C.

[tex]35x^2+41x+12 =[/tex] [tex](7x+4)(5x+3)[/tex]
Step-by-step explanation:
1) The general form of a quadratic is [tex]ax^2 + bx + c[/tex]. Hence, multiplying 35 by 12 gives you the product of ac, which is 420.
2) We need to find two numbers that multiply to 420 and add up to 41 simultaneously. If we pull out the factors of 420, two of them will be 20 and 21, which multiply to 420 as well as add up to 41.
3) Write [tex]41x[/tex] as a sum.
[tex]35x^2+20x+21x+12[/tex]
Now, we can factor them out by grouping.

Step-by-step explanation:
Given quadratic:
[tex]35x^2+41x+12[/tex]
Factoring quadratics by grouping
To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to ac and sum to b.
[tex]\implies ac=35 \cdot 12 = 420[/tex]
[tex]\implies b = 41[/tex]
Therefore, the two numbers that multiply to 420 and sum to 41 are:
20 and 21
Rewrite b as the sum of these two numbers:

Answer:
[tex]10^{0.4785+1.468x}=y[/tex]
Step-by-step explanation:
So I'm assuming when you typed "log yhat=.4785 + 1.468x", you meant to write: [tex]log(y)=0.4785+1.468x[/tex]. And generally a logarithm can be written in the form [tex]log_ba=c[/tex] which can then be rewritten as [tex]b^c=a[/tex], but since the log has no base, it's assumed to be 10. So in this case you have the equation:

calculate m using the slope formula

[tex]\implies 3^{2x}=3^3[/tex]
As both exponents have the same base,

First, combine both logarithms using the multiplication property and simplify the expression.

[tex]\log[ {x}^{2} + 99x ] = 2[/tex]
Now, use the definition of logarithm to transform the equation.
[tex] {10}^{2} = {x}^{2} + 99x[/tex]
[tex] {x}^{2} + 99x - 100 = 0[/tex]
Finally, use the quadratic formula to solve the equation.
[tex]x = \frac{ -99 ± \sqrt{ {99}^{2} - 4 \times 1 \times ( - 100)} }{2 \times 1} [/tex]
With this, we can say that the solution set is:
x = 1x = -100We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.
