A coin marked “0” and “1” is tossed an infinite number of times, the probability of 1 in any toss being equal to p 2 (0, 1). The resulting sequence (outcome) ! is parsed into consecutive blocks of increasing length: 2, 4, 6,..., etc. What is the likelihood that, in infinitely many of these blocks, the first half of the terms are either all 0’s or all 1’s?

Answer: 236 square inches

Step-by-step explanation:

Three 6" x 6" and two 8" x 8" electrical boxes are installed in a wall between two studs

The answer is 236

Based on the calculation below, the net income would have been 13,475 if income tax expense had been 23%.

The net income when the tax rate is 23% can be calculated as follows:

Income before tax = Income tax expenses at 25% tax rate / Tax tax rate = 4,375 / 25% = 17,500

Net income at 23% tax rate = Income before tax * (100% - Tax rate of 23%)

Net income at 23% tax rate = 17,500 * (100% - 23%)

Net income at 23% tax rate = 17,500 * 77%

Net income at 23% tax rate = 13,475

The domain of f(x) is all real numbers & satisfies function f(x+1)=2f(x).

For  x∈(0,1], the function f(x)=x(x-1). For value x∈(-[tex]\infty[/tex],m], f(x)≥[tex]\frac{-8}{9}[/tex]. What is the value of m?​

the smallest value m=[tex]\frac{7}{3}[/tex].

Given that, for x∈(0,1], f(x)=x(x-1)

Let's plot this function

We'll go from 0 to 1 and let's graph what this function is look like

f(x)=x(x-1) will be a parabola and it's going to go between the points (0,0) and (1,0).

Will graph it in figure1 we can see.

The minimum value of this parabola is right in the middle and it is

f(0.5)=-0.25

Now, let try and graph the function in the other intervals

We know f(x+1)=2f(x)

Now we can evaluate couple of points

f(0+1)=2f(x)

f(0.5+1)=2f(0.5)

f(1+1)=2f(1)

And we quickly deduce that the graph in(1,2] is twice the height of the graph in (0,1].

We will graph a parabola in figure 2 we can see.

This parabola is going to have a graph of 2 between its twice as tall and this can be multiplied by the quantity of (x-1) multiplied by the quantity of (x-2).

It is 2(x-1)(x-2).

We graph next interval twice the height of the graph in the interval from 2 to 3. We can see the graph in figure3.

This parabola will have an equation 4 times the quantity of (x-2) and (x-3).

We can also shift this graph to the left and it going to be half the height.

Looking at this graph we want f(x)≥[tex]\frac{-8}{9}[/tex].

In the 3 interval from 2 to 3 its going to intersect .

we want to look for the points where f(x)≥[tex]\frac{-8}{9}[/tex].

We are looking for m which f(x)≥[tex]\frac{-8}{9}[/tex].

parabolas equation =[tex]\frac{-8}{9}[/tex].

4(x-2)(x-3)=[tex]\frac{-8}{9}[/tex]

[tex]x^{2} -5x+6=\frac{-2}{9} \\(x-\frac{7}{3})(x-\frac{8}{3})=0\\ x= \frac{7}{3},\frac{8}{3}\\\\[/tex]

Therefore, We will take the smallest value m=[tex]\frac{7}{3}[/tex].

Answer:

the second option

[–3, 6) ∪ (6, ∞)

Step-by-step explanation:

f(x) = 1/(x - 3)

the domain is every value of x that does not turn the denominator to 0. so, x <> 3.

g(x) = sqrt(x + 3)

the domain is every value of x that does not turn (x+3) into a negative value. so, x >= -3.

f(g(x)) = 1/(sqrt(x + 3) - 3)

the domain is all values of x that are valid for g(x) AND that do not generate range values of g(x) that violate the domain of f(x).

so, it is (x >= -3) AND (sqrt(x + 3) <> 3).

and sqrt(x + 3) = 3, if (x + 3) = 9.

that means x = 6.

so, 6 is forbidden, every other value of x is allowed here.

therefore, the domain of f(g(x)) is

(x >= -3) AND (x <> 6)

and that is equivalent to

[-3, 6) u (6, infinity)

everything larger or equal to -3 and different from 6.

Using proportions, it is found that the total amount of cement, sand, and gavel required is of 55.2 cubic yards.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The decimal equivalent to the mixed number 1 1/2 is given by:

1 + 1/2 = 1 + 0.5 = 1.5.

1.5 times 36.8 cubic yards is:

1.5 x 36.8 = 55.2.

Answer:

Step-by-step explanation:

The percentage of the actual salary that actual mortgage is is 30%.

Percentage is the fraction of an amount that is expressed as a number out of hundred. Percentage is a measure of frequency. The sign used to show percentage is %.

In order to transform a number into a percentage, express it as a fraction of a total amount and multiply by 100. So, actual mortgage would be divided by actual budget, the fraction would then be multiplied by 100.

Percentage of actual salary that is actual mortgage  = (actual mortgage / actual salary) x 100

The value of the variable x will be 88. Then the length of the side RS will be 84.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If two triangles are similar, then the ratio of the corresponding sides will remain constant.

Triangle BCD has the following side lengths: BC = 60, CD = 50.

Triangle RST has the following side lengths: RS = 11x-4, ST = 70.

The triangle BCD and RST are similar triangles. Then we have

RS / ST = BC / CD

11x - 4 / 70 = 60 / 50

11x - 4 = 84

11x = 88

x = 8

Then the length of the side RS will be

RS = 11x - 4

RS = 11 × 8 - 4

RS = 88 - 4

RS = 84

The value of the variable x will be 88. Then the length of the side RS will be 84.

6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.

Given,

The expression : 6x³ + 2x² + 3x - 4

We have to divide the given expression by x² + 3x - 4.

Let's take 6x³ + 2x² + 3x - 4 as p(x) and x² + 3x - 4 as g(x).

If p(x) is divisible by the factors of g(x), then p(x) is divisible by g(x).

So, let's factorize  x² + 3x - 4

x² + 3x - 4 = (x - 1) (x + 4)

Now,

p(x) = 6x³ + 2x² + 3x - 4

By using remainder theorem,

If p(1) = 0 and p(4) = 0, then p(x) is divisible by g(x).

So,

p(1) = 6 × 1³ + 2 x 1² + 3 x 1 -4

p(1) = 6 + 2 + 3 - 4

p(1) = 11 - 4

p(1) = 7

Next,

p(4) = 6 x 4³ + 2 x 4² + 3 x 4 - 4

p(4) = 6 x 64 + 2 x 16 + 12 - 4

p(4) = 384 + 32 + 12 - 4

p(4) = 424

Here, p(1) and p(4) is not 0.

So, p(x) is not divisible by g(x).

That is, 6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.

(h) x = 3 which is a relative maximum point

(i) the value of x is 3 for which f(x) = 3

(j) the function would be positive if f(0)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The domain of the function shown in the graph is given by the set of values x that has a point on the graph.

In other words, by launching the graph onto the x-axis we will cover the interval (−3,6]

The range of the function shown in the picture is given by the set of values y that has a point on the graph.

In other words, by launching the graph onto the y-axis we will cover the interval (−6,3]

The zeros of the function are the x-intercepts of the function, so the zeros are x = −0.5 and x=6.

The value of f(-3.5) is given by the y- coordinate of the point of intersection of the graph with the vertical line x=-3.5 So, f(-3.5)≈2.

The function is increasing whenever the y- coordinate increases if we trace the graph in the direction of positive x values.

So, the graph is increasing on (−3,3), where x=3 corresponds to the x- coordinate of the turning point on the graph.

The function is decreasing whenever the y- coordinate decreases if we trace the graph in the direction of positive x values.

So, the graph is decreasing on (3,6].

The values of x where f(x) ≤0, correspond to the points where the graph is below the x-axis, so the values of x for which f(x) ≤0 are (−3,−0.5].

The relative maxima or minima are the x-coordinate points where the continuous function has a turning point, like x=3 which is a relative maximum point

.

There are no relative minimum points for the given function.

The value of x for f(x)=3 is the x- coordinate of the point of intersection of the graph with the horizontal line y=3

So, x≈3.

we will determine the  y = coordinate of the point of intersection of the graph with the vertical line

x=0, which is above 2, so f(0) is positive.

Therefore, the domain of the function is interval (−3,6], and the range of the function is interval (−6,3].
