Answer:

[tex]=-\frac{37}{24}[/tex]

Step-by-step explanation:

[tex]-\frac{2}{3}+\left(-\frac{7}{8}\right)[/tex]
[tex]=-\frac{2}{3}-\frac{7}{8}[/tex] <- Apply the rule a + (-b) = a - b
[tex]=-\frac{16}{24}-\frac{21}{24}[/tex] <- The LCM of 3 and 8 is 24.
[tex]=\frac{-16-21}{24}[/tex] <- Apply the fraction rule [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]=\frac{-37}{24}[/tex] <- Subtract
[tex]=-\frac{37}{24}[/tex] <- Apply the fraction rule [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

Answer:

-1.542

Step-by-step explanation:

(-2/3) + (-7/8)=-37/24=-1 13/24= -1.542

Using exponent properties, the equivalent expression is given as follows:

[tex]\left(\frac{2}{3}\right)^14[/tex]

Two thirds to the fourth power is given by:

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

Two thirds to the third power is given by:

[tex]\left(\frac{2}{3}\right)^3[/tex]

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:

[tex]\left(\frac{2}{3}\right)^4 \times \left(\frac{2}{3}\right)^3 \left(\frac{2}{3}\right)^{4 + 3} = \left(\frac{2}{3}\right)^7[/tex]

Then, this entire expression is raised to the second power, meaning that:

[tex]\left[\left(\frac{2}{3}\right)^7\right]^2 = \left(\frac{2}{3}\right)^7 \times \left(\frac{2}{3}\right)^7 = \left(\frac{2}{3}\right)^{7+7} = \left(\frac{2}{3}\right)^14[/tex]

[tex]\left(\frac{2}{3}\right)^14[/tex] is the equivalent expression.

Step-by-step explanation:

Leah should multiply x with [tex]\frac{12}{5}[/tex].

If we are to divide x by  [tex]\frac{5}{12}[/tex], we need to write it like this,

[tex]\frac{x}{\frac{5}{12} }[/tex]

⇒ x ÷ [tex]\frac{5}{12}[/tex]

⇒ x × [tex]\frac{12}{5}[/tex]

Thus, x should be multiplied  [tex]\frac{12}{5}[/tex] to get the answer.

Answer)  [tex]\frac{12}{5}[/tex]

          In fractional division, we need to find the reciprocal of the divisor fraction and then multiply it with the dividend to find the solution.

         In the given question, the divisor is ' [tex]\frac{5}{12}[/tex].' Thus, it should be reciprocated to find the fraction '   [tex]\frac{12}{5}[/tex].' This should be then multiplied by the variable x to find the answer to the fractional division.

The equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is  y = 4x ₋ 2.

The slope of the preceding equation is 4 because it is in slope intercept form. The slope of an equation is always equal for parallel lines, hence the slope of the equation we are requested to create is also 4.  We are given that this line passes through (2,6).

In the absence of intersection, two lines are said to be parallel. Each line has the same slope. In the event where m₁=m₂, f(x)=m₁x+b₁ and g(x)=m₂x+b₂ are. parallel

In order to write in y = mx +b form, we need to solve for b (the y-intercept).  

Given, x=2, y=6, and m = 4.

6 = (4) (2) ₊ b

simplify

6 = 8 ₊ b

solve for b.

b = 6 ₋ 8

b = ₋2

So the equation of the parallel line is   y = 4x ₋ 2

Hence we get the equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is y = 4x ₋ 2

Answer: 32604

Step-by-step explanation:

The value of d is 18.

Given, the slope of the line is 3.

Slope equals a height change (Change in width) You may also say that a slope is a climb or a run. This formula changes if the graph's horizontal axis is represented by x and the vertical axis by y: Slope is equal to (y-change)/ (Change in x)

Two points which lie are N(₋2 , 3) and D(3,d)

slope of the line = y₂ ₋ y₁/x₂ ₋ x₁

let the points N(₋2 , 3) be (x₁ , y₁)

and D(3,d) be (x₂ , y₂)

therefore, 3 = d ₋ 3/3 ₋ (₋2)

3 = d ₋ 3/3 ₊ 2

3 = d ₋ 3 / 5

15 = d ₋ 3

d = 15₊3

d = 18

Step-by-step explanation:

You would think 6.7% is a lot bigger than both, but it is not. Remember 6.7 is a percentage out of 100, thus, 6.7% actually is 0.067.

Answer:

width = 6 ft

length = 21 ft

Step-by-step explanation:

Forming algebraic expressions and finding the dimensions of a rectangle:

 Width = w ft

 length =  3*w + 3 = (3w + 3) ft

              2l +2w = P

 2(3w + 3) + 2w = 54

Use distributive property to open the brackets,

 2*3w + 2*3 + 2w = 54

        6w + 6 + 2w = 54

Combine like terms,

          6w + 2w + 6 = 54

               8w   + 6   = 54

Subtract 6 from both sides,

                      8w    = 54 - 6

                         8w = 48

Divide both sides by 8

                           w = 48 ÷ 8

                           [tex]\sf \boxed{\bf w = 6 \ ft}[/tex]

First distribution;

Second distribution;

The Z–Score percentile normal distribution table can be used to find the Z–Score that gives the percentile value of a raw score.

The Z–Score, also known as the standard score, gives the number of standard deviations, a raw score is far from the mean.

The mathematical equation for the Z–Score is as following; [tex]Z = \frac{x - \mu}{ \sigma} [/tex]

Therefore, a positive value of Z is obtained when the raw score, x, is larger than the mean, [tex] \mu[/tex]

and negative Z value is given by raw scores lower than the mean.

Using the standard normal distribution table, raw score corresponds to the 1th percentile when the Z–Score = -2.326, while the Z–Score for the 99th percentile is 2.326.

The Z–Score of the 20th percentile is -0.842, while for the 30th percentile it is -0.524

Comparing the standard values with the values in the given table, we have;
