Answer:

Percent form: 41.65%

Fraction form: [tex]\frac{833}{2000}[/tex]

Step-by-step explanation:

33% of men support John Smith.

67% of women support John Smith.

Lets say, for instance, that there are 20 polled individuals -- 10 women and 10 men.

However, since 1.5 times as many men voted as women, we have to apply our poll to 15 men and 5 women.

33% of the 15 men makes 5 men who voted for Smith and 10 who did not.

67% of the 5 women makes 3.33 women who voted for Smith and 1.67 who did not.

Add these numbers together.

8.33 total voters were cast for John Smith, while 11.67 were not.

Now, divide 8.33 by 20 and multiply by 100 to obtain a percentage.

[tex]\frac{8.33}{20} \\.4165\\41.65[/tex]

41.65% of voters voted for John Smith according to the results of the poll.

According to an informal poll, with 1/3 of men and 2/3 of women supporting John Smith, and 1.5 times more men than women voting, 2/3 of the total vote should be cast for John Smith.

We need to calculate the fraction of the total vote that would be cast for John Smith according to the informal poll. Let's denote the number of women voters as w and the number of men as m. According to the poll, 1/3 of men and 2/3 of women will vote for John Smith. On election day, 1.5 times as many men as women voted, which means m = 1.5w.

The total votes for John Smith would be (1/3)m + (2/3)w. Substituting m with 1.5w, we get:

Total votes for John Smith = (1/3)(1.5w) + (2/3)w

This simplifies to:

Total votes for John Smith = 0.5w + (2/3)w = (1.5/3)w + (2/3)w = (1.5/3 + 2/3)w = (3/3 + 2/3)w = (5/3)w

The total votes cast would be m + w, substituting again we get 1.5w + w = 2.5w.

To find the fraction of total votes that would be for John Smith, we divide the total votes for John Smith by the total votes cast:

Fraction for John Smith = (5/3)w / (2.5)w

Since w is in both the numerator and denominator, it cancels out, and we're left with:

Fraction for John Smith = (5/3) / (2.5)

Converting 2.5 to a fraction gives us 5/2, so:

Fraction for John Smith = (5/3) / (5/2)

By dividing fractions, we invert and multiply:

Fraction for John Smith = (5/3) * (2/5) = 2/3

Therefore, according to the poll, 2/3 of the total vote should be cast for John Smith.

Answer:

Step-by-step explanation:

This is a question that uses the Pythagorean Theorem.

a = 35 feet

b = x            which is the height of the tree.

c = 3*x + 1   so we are trying to find x.  Substitute into a b and c

a^2 + b^2 = c^2

35^2 + x^2 = (3x + 1)^2        

35^2 + x^2 = 9x^2 + 6x + 1     Subtract x^2 from both sides.

35^2 = 8x^2 + 6x + 1               Subtract 35^2 from both sides.

0 = 8x^2 + 6x + 1 - 35^2

0 = 8x^2 + 6x - 1224

Does this factor?

(x + 12.75)(x - 12)

x - 12 = 0 is the only value that works.

x = 12

The tree is 12 feet high.

Note: I used the quadratic formula to solve this.

Answer:

12 ft

Step-by-step explanation:

Let the height of the tree is h.

So the distance of top of the tree = 3 h + 1

Distance of base of tree = 35 ft

So, by use of Pythagoras theorem

[tex]\left ( 3h+1 \right )^{2}=h^{2}+35^{2}[/tex]

[tex]8h^{2}+6h-1224=0[/tex]

[tex]4h^{2}+3h-612=0[/tex]

[tex]h=\frac{-3\pm \sqrt{9+4\times 4\times 612}}{8}[/tex]

[tex]h=\frac{-3\pm 99}{8}[/tex]

Take positive sign

h = 12 ft

Thus, the height of tree is 12 ft.

Answer:

Step-by-step explanation:

Hey diddle diddle the medians in the middle you add then divide for the mean. the mode is the one that appears the most and the range is the difference in between.

Median: you have to organize the numbers from least to greatest then eliminate one by one.

12, 15, 15, 18, 20, 29, 33, 42

eliminate 12, and 42

15, 15, 18, 20, 29, 33

eliminate 15, and 33 ... so on

once you get to the median you end up with two numbers.

18, 20

because you can only have one median you find the number between, which in this case would be 19

Answer:

19

Step-by-step explanation:

The median is the middle value of the data in ascending order. If there is no exact middle then it is the average of the two values either side of the middle.

Arrange in ascending order

12, 15, 15, 18, 20, 29, 33, 42

The middle is between 18 and 20

median = [tex]\frac{18+20}{2}[/tex] = [tex]\frac{38}{2}[/tex] = 19

Answer:

0.5

Step-by-step explanation:

Sort the given data in ascending order:

47, 48, 50, 52, 53, 53, 55, 68

Possible outlier is number 68. Check whether this number is an outlier:

[tex]Q_1=49\\ \\Q_2=52.5 \\ \\Q_3=54[/tex]

The interquartile range is

[tex]Q_3-Q_1=54-49=5[/tex]

Multiply it by 1.5:

[tex]1.5\cdot 5=7.5[/tex]

and add to third quartile:

[tex]7.5+54=61.5[/tex]

Since [tex]68>61.5,[/tex] number 68 is an outlier.

The median of the sample with outlier is [tex]Q_2=\dfrac{52+53}{2}=52.5[/tex]

The median of the sample without outlier is 52

The difference between the median of the data, including the possible outlier and excluding the possible outlier is 52.5-52=0.5

Answer:

60(1/5)^(n-1).

Step-by-step explanation:

The common ratio  r   is 12/60 = 12/5 / 12  = 12/25 / 12/5 = 1/5.

The first term a1 = 60 so the explicit rule is

a1 * r^(n-1)

= 60(1/5)^(n-1).

aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .This can be obtained by using the formula of geometric sequence.

Sequence is s collection of objects in a particular order and repetitions are allowed.

Geometric Sequence:

In the given question, first term a=60

Common ratio r = a₂/a₁ = 12/60 = 1/5 ⇒ r = 1/5

By definition, arⁿ⁻¹ = (60)(1/5)ⁿ⁻¹ is the required explicit rule for the geometric sequence.

Hence aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .

height of prism = [tex]x+1-\frac{4}{x^3+3x^2+8}[/tex]

Step-by-step explanation:

Volume of rectangular prism = (x^4+4x^3+3x^2+8x+4)

Area of its bases = (x^3+ 3x^2+8)

Height of prism = ?

Volume of rectangular Prism = Area of its bases * Height of prism

(x^4+4x^3+3x^2+8x+4) = (x^3+ 3x^2+8) * height of prism

=> height of prism = (x^4+4x^3+3x^2+8x+4) /(x^3+ 3x^2+8)

=> height of prism = [tex]x+1-\frac{4}{x^3+3x^2+8}[/tex]

Answer:

the radius of the circle= 4m

Step-by-step explanation:

Given:

Area of circle=16π m2

radius,r of circle=?

Formula of area of circle is given as

Area=πr^2

Putting values we get

16π=πr^2

r^2=16

r=4

the radius of the circle= 4m !

Given the area [tex]A=\pi r^2=16\pi[/tex] we can solve the formula for radius.

[tex]A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}[/tex]

So,

[tex]r=\sqrt{\dfrac{16\cdot\not{\pi}}{\not{\pi}}}=\sqrt{16}=4[/tex]

The radius is 4m.

Hope this helps.

Answer:

Option C) 8 cups

Step-by-step explanation:

Let

x----> the number of cups

y ---> the number of plates

we know that

y=2x-4 -----> equation A

60%=60/100=0.60

y=0.60(x+y) ----> equation B

Substitute equation A in equation B and solve for x

2x-4=0.60(x+2x-4)

2x-4=0.6x+1.2x-2.4

2x-4=1.8x-2.4

2x-1.8x=4-2.4

0.2x=1.6

x=1.6/0.2

x= 8 cups

Answer:

They can buy 160 commercial vans, 80 small trucks and 40 large trucks.

Step-by-step explanation:

The company plans to spend $8 million on 280 new vehicles.

Commercial van = $25,000

Small truck = $30,000

Large Truck = $40,000

Let 'x' be commercial van, 'y' small truck and 'z' large truck. Therefore:

x + y + z = 280

Also, we know that x = 2y

Therefore: 3y + z = 280

Also we know that:

25,000x + 30,000y + 40,000z = 8,000,000

50,000y + 30,000y + 40,000z = 8,000,000

80,000y + 40,000z = 8,000,000

Therefore, we need to solve the following system of equation:

3y + z = 280  [1]

80,000y + 40,000z = 8,000,000  [2]

We have that the results are: y=80, z=40 and x=160.

Therefore, they can buy 160 commercial vans, 80 small trucks and 40 large trucks.

Final answer:

To find f(10) using a recursive formula, we can calculate intermediate values starting from f(1) and applying the given rule to find f(10) as 2.

Explanation:

The function is defined as follows:

f(1)=-1.5

f(n+1)=f(n)+0.5

To find f(10), we can use the given recursive formula to calculate subsequent values:

f(2) = f(1) + 0.5 = -1.5 + 0.5 = -1

f(3) = f(2) + 0.5 = -1 + 0.5 = -0.5

Continuing this pattern, we find f(10) = 2

Answer:

The correct option is A) Q and W are similar but not congruent.

Step-by-step explanation:

Consider the provided graph.

Figure Q is a quadrilateral with sides measuring 5 and 2

Figure S is a quadrilateral with sides measuring 5 and 2.

Figure W is a quadrilateral with sides measuring 10 and 4.

Two figures are similar if the shape of the figures are same but not necessarily same size.

Two figures are congruent if the size and shape of the figure are same.

Note: If two figures are congruent, then they are also similar, but converse is not true.

The dimensions of Q is equals to the corresponding dimensions of the rectangle S. Thus, Q and S are similar and congruent as they have the same shape and the same size.

The dimension of quadrilateral W is 2 times of quadrilateral Q and S. Thus the dimensions of W is proportional to dimensions of Q.

That means quadrilateral W is similar to Q and S but not congruent.

Thus, the correct option is A) Q and W are similar but not congruent.

An inequation is a mathematical statement that represents an inequality relationship between two expressions. It compares the relative values of the two expressions, indicating whether one is greater than, less than, or not equal to the other.

Solving an inequation involves finding the values of the variables that satisfy the inequality. This can often be done by using algebraic techniques, such as simplifying and rearranging the expressions, isolating the variable, and applying appropriate rules and operations.

To solve the above inequation, let's assume that it is an equation.

Explanation:

To break the inequality 18x 6> 12x 18, we need to insulate the variable x on one side.

Abate 12x from both sides 18x- 12x 6> 18.

Simplify the equation 6x 6> 18.

Abate 6 from both sides 6x> 12.

Divide both sides by 6 to break for x x> 2.

The result to the inequality is x lesser than 2. This gives a range of values for x that will satisfy the original inequality. thus, any number lesser than 2 for x makes the inequality true.

Answer:

y = - 4x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 5 is in this form with slope m = - 4

• Parallel lines have equal slopes, hence

y = - 4x + c ← is the partial equation of the parallel line

To find c substitute (4, - 21) into the partial equation

- 21 = - 16 + c ⇒ c = - 21 + 16 = - 5

y = - 4x - 5 ← equation of parallel line
