Answer:

shade the area where circles overlap

Answer:

Shade the middle section.

Step-by-step explanation:

Venn-diagrams show what is the same or different. Adam does both chorus and singing lessons. The part of the diagram where the circles cross in the middle is what you would shade in because that section represents both chorus and singing lessons.

Answer: Prokhorova is more outstanding.

Step-by-step explanation: To compare scores from different distributions, first standardize it:

z-score = [tex]\frac{x-\mu}{\sigma}[/tex]

where

x is the individual mean you want to compare

μ is the mean of the population

σ is standard deviation

For Gertrud Bacher:

z-score = [tex]\frac{129-137}{5}[/tex]

z-score = [tex]-1.6[/tex] (s)

The negative sign indicates Bacher's mean is less than the mean

For Yelena Prokhorova:

z-score = [tex]\frac{660-600}{30}[/tex]

z-score = 2 (cm)

The positive sign indicates Prokhorova's mean is more than the mean.

Using z-score table, you determine the percentiles are:

For Bacher: Percentile = 5.5%

For Prokhorova: Percentile = 97.7%

Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.

Answer:

Step-by-step explanation:

If person A can paint the house in 'a' days, then person B takes 3a days. Each day, the total amount of house painted when they work together is ...

  1/a + 1/(3a) = 1/10

  4/(3a) = 1/10 . . . combine terms

  40 = 3a . . . . . . . cross multiply

  a = 40/3 = 13 1/3 . . . . . divide by 3

A can paint the house in 13 1/3 days.

B can paint the house in 40 days.

C.  [tex]x=-9 \textsf{ and }x=1[/tex]

Step-by-step explanation:

[tex](x+4)^2=25[/tex]

[tex](x+4)(x+4)=25[/tex]

expand the brackets:

[tex]x^2+8x+16=25[/tex]

subtract 25 from both sides:

[tex]x^2+8x-9=0[/tex]

factor:

[tex]x^2+9x-x-9=0[/tex]

[tex]x(x+9)-1(x+9)=0[/tex]

[tex](x-1)(x+9)=0[/tex]

solve for x:

[tex]x-1=0 \implies x=1[/tex]

[tex]x+9=0 \implies x=-9[/tex]

[tex]2 \log_{a}(2x-1)=\log_{a}(2x-1)^{2}[/tex]

[tex]2=\log_{a}(a^{2})[/tex]

So the expression can be expressed as a single logarithm as follows:

[tex]3\log_{a}(2x+1)-2\log_{a}(2x-1)+2=\log_{a}(2x+1)^{3}-\log_{a}(2x-1)^{2}+\log_{a}a^{2}[/tex]

[tex]3\log_{a}(2x+1)-2\log_{a}(2x-1)+2=\log_{a}\left(\frac{(2x+1)^{3}a^{2}}{(2x-1)^{2}}\right)[/tex]

Answer:

a=4/3

Step-by-step explanation:

Opening the brackets,

Answer: Mode = 33, Mean = 35.5

Step-by-step explanation: The mode is whatever number appears the most.

To find the mode, first put the numbers in order from least to greatest.

29, 31, 33, 33, 37, 38, 40, 43

In this case, 33 appears the most, so the mode is 33.

The mean is the average of all of the numbers.

Firstly, add up all of the numbers:

29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284

Now that you have all of them added up, divide the final sum by the number of numbers you have in the list. In this case, you have 8 numbers.

284/8 = 35.5

Your mean is 35.5

Answer:

Mode = 33

Mean = 35.5

The mode is whatever number appears the most.

to find the mean:

add all the numbers:

29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284

divide that by the number of numbers you have in the list.

284/8 = 35.5

mean = 35.5

Answer:

Step-by-step explanation:

(x-1)^5 = x^5 - 5x^4 + 15x^3 - 15x^2 + 5x - 1

That has 6 terms, so let's get rid of the two middle ones.

f(x) = (x-1)^5 - 15x^2(x-1)

Now, f(0) = 1, but we want f(0) = 12

So, let

f(x) = 12((x-1)^5 - 15x^2(x-1)) = 12x^5 - 60x^4 + 60x - 12

As for the graph, it looks like

y = (x+4)(x+2)(x-1)^2(x-6)

The extrema appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)

The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The degree of the polynomial is 5.

The polynomial has 4 terms

So (x-1)⁵ = x⁵ - 5x⁴ + 15x³ - 15x² + 5x - 1

Let's eliminate the two middle terms from it, which has six.

f(x) = (x-1)⁵ - 15x²(x-1)

Given that the graph of the polynomial crosses the vertical axis at Y = 12

So, substitute f(0) = 1, but we determine f(0) = 12

So, let f(x) = 12((x-1)⁵ - 15x²(x-1)) = 12x⁵ - 60x⁴ + 60x - 12

As for the graph, it looks like

So the approximate input values of relative maximums and minimums of this 5th-degree polynomial :

y = (x+4)(x+2)(x-1)²(x-6)

The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)

Answer:

x = 80

Step-by-step explanation:

the total of interior angles in a quadrilateral (any shape with only 4 sides) is 360

add the angles you're given

105 + 100 + 75 = 280

subtract that number from the total interior angles (360)

360 - 280 = 80

therefore, x = 80

If the formatting should be [tex]\frac{\frac{5}{6} }{p} =\frac{\frac{2}{3} }{\frac{1}{2} }[/tex], then this should be correct.

Answer:

p = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

[tex]\frac{\frac{5}{6} }{p} =\frac{\frac{2}{3} }{\frac{1}{2} }[/tex]                 [Given]

[tex]\frac{5}{6} *\frac{1}{p} =\frac{\frac{2}{3} }{\frac{1}{2} }[/tex]            [Keep, change, and flip on the left side]

[tex]\frac{5}{6} *\frac{1}{p} =\frac{2}{3}*2}[/tex]       [Keep, change, and flip on the right side]

[tex]\frac{5}{6} *\frac{1}{p} =\frac{4}{3}}[/tex]            [Simplify the right side]

[tex]\frac{5}{6p}=\frac{4}{3}}[/tex]                [Simplify the left side]

6p * 4 = 5 * 3    [Cross multiply]

24p = 15            [Simplify]

p = [tex]\frac{15}{24}[/tex]                 [Divide both sides by 24]

Answer:

A

Step-by-step explanation:

We have the two functions: [tex]f(x)=1-x^2[/tex] and [tex]g(x)=x^2-1[/tex].

And we want to find the value of b such that [tex]f(3b)+8=g(3b)-8[/tex] is true.

Notice that we can multiply f(x) by -1. This yields:

[tex]-f(x)=x^2-1[/tex]

Notice that this is the same as g(x). Therefore:

[tex]-f(x)=g(x)[/tex]

If we substitute 3b for x:

[tex]-f(3b)=g(3b)[/tex]

So, we can go back to our equation. We have:

[tex]f(3b)+8=g(3b)-8[/tex]

Substitute -f(3b) for g(3b):

[tex]f(3b)+8=-f(3b)-8[/tex]

Solve. Subtract 8 from both sides and add f(3b) to both sides:

[tex]2f(3b)=-16[/tex]

Divide both sides by 2:

[tex]f(3b)=-8[/tex]

Now, we can use the function of f(x). Substitute 3b into f(x). So:

[tex]1-(3b)^2=-8[/tex]

Subtract 1 from both sides:

[tex]-(3b)^2=-9[/tex]

Divide both sides by -1:

[tex](3b)^2=9[/tex]

Take the square root of both sides:

[tex]3b=\pm 3[/tex]

Divide both sides by 3. So, the value of b can be:

[tex]b=-1, 1[/tex]

Therefore, our answer is A.

And we're done!

Answer:

A.1

Step-by-step explanation:

f(x) = 1 - x² ⇒ f(3b) = 1 - (3b)² = 1 - 9b²

g(x) = x² - 1 ⇒ g(3b) = (3b)² - 1 = 9b² - 1

f(3b) + 8 = g(3b) - 8 ⇒ (1 - 9b²) + 8 = (9b² - 1) - 8

⇔ 9 - 9b² = 9b² - 9

⇔ 9 + 9 = 9b² + 9b²

⇔ 18 = 18b²

⇔ b² = 1

⇒ b = 1; - 1

Answer:   y = [tex]-\frac{2}{1.5}[/tex]x + 15

Step-by-step explanation:

Slope intercept form is written as y = mx + b, where m is the slope and b is the y- intercept.

2.00x + 1.50y = 15

             1.50y = -2.00x + 15

                    y = [tex]\frac{-2}{1.5}[/tex]x + 15  

Answer:

The y intercept is (0,4.5)

Step-by-step explanation:

Because the y-intercept occurs at x = 0, we can substitute this into our equation and solve for y.

3(0) +2y = 9

2y = 9

y=4.5

Answer:

[tex]\boxed{(0 , 4.5)}[/tex]

Step-by-step explanation:

→ Rearrange into y = mx + c format

2y = - 3x + 9

→ Divide everything by 2

y = -1.5x + 4.5

→ Substitute x = 0

y = 0 + 4.5 ⇒ 4.5
