[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3}{16}[/tex]

Step-by-step explanation:

Given

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2[/tex]

Required

Solve:

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2[/tex]

Apply law of indices

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{4^3} * \frac{2^2}{3^2}[/tex]

Express 4 as 2^2

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{(2^2)^3} * \frac{2^2}{3^2}[/tex]

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{2^6} * \frac{2^2}{3^2}[/tex]

Express as a singe fraction

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3*2^2}{2^6*3^2}[/tex]

Apply law of indices:

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^{3-2}}{2^{6-2}}[/tex]

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^1}{2^4}[/tex]

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3}{16}[/tex]

Answer:

n=1

Step-by-step explanation:

N is the number of times per year

Annually would be one time per year so n =1

Answer:

If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Answer:

Step-by-step explanation:

The mean for 2018 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2018 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{30}{7} }[/tex]

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2019 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{194}{7} }[/tex]

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Answer:

y = -2x + 8

Step-by-step explanation:

(−6, 20) and (0, 8)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(8 - 20) / (0 - (-6))

Simplify the parentheses.

= (-12) / (6)

Simplify the fraction.

-12/6

= -2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.

8 = -2(0) + b

To find b, multiply the slope and the input of x(0)

8 = 0 + b

b = 8

Plug this into your standard equation.

y = -2x + 8

This is your equation.

Check this by plugging in the other point you have not checked yet (-6, 20).

y = -2x + 8

20 = -2(-6) + 8

20 = 12 + 8

20 = 20

Your equation is correct.

Hope this helps!

Answer:

Simplifying

x = 4.5 + -0.5y

Step-by-step explanation:

The boundary line of the inequality is intersecting the x-axis at 4.5.

The given inequality is 4x + 2y < 18.

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Graph the inequality by finding the boundary line, and then shading the appropriate area.

Now, 4x + 2y < 18 can be written as y<−2x+9.

The boundary line of the inequality is given below.

The boundary line of the inequality is intersecting the x-axis at 4.5.

Answer:

True: The smaller angle is 36°; The larger angle is 54°

False: The smaller angle is 18°. The larger angle is 72°

If you create an equation using this scenario, it would be (18+x)+x=90, because complementary angles sum up to 90°. Add the like terms to get 18+2x=90. Subtract 18 on both sides to get 72. Divide 2 on both sides to result with x=36. Subtract 90 with 36 to get 54. The smaller angle is 36° and the larger angle is 54°.

Step-by-step explanation:

The vertex of the function f(x) = x²+10 is (0,10). Correct option is (A).

Vertex form of equation is an alternate way of writing the equation of a parabola

The vertex form of an equation is
f(x)= a(x-h)²+k,

Here, h and k are constants

The given equation is,

f(x) = x²+10

To determine the vertex of the equation,

substitute x=0,

f(x)=0+10

f(x)=10

The vertex of the function f(x) is (0,10).

For this case we can see the table as a set of ordered pairs.

We then have the following ordered pairs:

(-6, -7)

(-1,1)

(0, 9)

(3, -2)

Then, the domain of the function is represented by all the values of x.

We have then:

There are 60 girls and 40 boys in the class.

Step-by-step explanation:

Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:

1 x 75 + 0 x 65 + 75

0.9 x 75 + 0.1 x 65 = 74

0.8 x 75 + 0.2 x 65 = 73

0.7 x 75 + 0.3 x 65 = 72

0.6 x 75 + 0.4 x 65 = 71

Thus, there are 60 girls and 40 boys in the class.
