Ms. Walker paid $0.918*p for the computer including sales tax .

In the question ,

it is given that

discount on list price for the computer is 15%

sales tax = 8%

let the list price for the computer be $p  .

So, sales price is = p - 0.15*p = 0.85*p

tax on sale price is = 8% of 0.85*p = 0.08*0.85*p = 0.068*p

Total Price = sale price + tax on sale price

Substituting the values of tax and sale price ,

we get

total price = 0.85*p + 0.068*p

= 0.918*p

Therefore , she paid $0.918*p for the computer including the sales tax .

The solution to the given expression is 7,677.6.

This is a question of multiplication.

Multiplication

In mathematics, multiplication is used as a method of finding the product of two or more numbers. It is one of the arithmetic operations,  like addition, subtraction and division that we use in everyday life. The major application we can see in multiplication tables.

In arithmetic, the multiplication of two numbers is represented by  the repeated addition of one number with respect to another.

Given expression:-

[−3*914]*[(−0.1)*(−28)]

We have to find the solution of the given expression.

We have,

-3*914 = -2742

(-0.1)*(-28) = 2.8

Hence, we can write,

[−3*914]*[(−0.1)*(−28)] = (-2742)*(2.8)

(-2742)*(2.8) = 7,677.6

They will next meet again after 1386 seconds or 23.1 minutes from the starting point.

Given that Robert, John, and Paul begin running in the same direction from the same starting point around a circular track If they take 126 seconds, 154 seconds, and 198 seconds respectively to complete one round of the track.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

To determine whether they will next meet again at the starting point.

We have to calculate the LCM of the numbers 126, 154, and 198

⇒ Prime factors of 126 = 2 × 2 × 3 ×7

⇒ Prime factors of 154 = 2 × 11 ×7

⇒ Prime factors of 198 = 2 × 3 × 3 ×11

So the LCM of the numbers 126, 154, and 198 will be as:

⇒ 2 × 3 × 3 × 7 × 11 = 1386

Therefore, they will meet after 1386 seconds or 23.1 minutes.

Step-by-step explanation:

Based on the right triangle altitude theorem, the term that completes the equation is: a. YZ.

The right triangle altitude theorem state that when an altitude is drawn to from the vertex of a right triangle to intersect the opposite side perpendicularly, the length of the altitude would be equal to the geometric mean of the line segments that are formed by the altitude on the right triangle's hypotenuse.

In other words, the square of the length of the altitude equals the product of the line segments formed, according to the right triangle altitude theorem.

XZ = altitude

WY = hypotenuse

WZ and YZ are the line segments formed.

Therefore, the equation would be:

If the function f(3) has a value of 6, then the value of f⁻¹(6) is 3

From the question, the definition of the function is given as

f(x)

Such that

The value of f(3) is 6

This is represented as

f(3) = 6

Also, the function can be represented as

y = f(x)

In f(3) = 6, we have

x = 3 and y = 6

Step-by-step explanation:

9+4 spots times five days

The powers of the imaginary number i have four possible values: 1, i, -1, and -i. Let's see some examples:

i⁰ = 1 (any number with the exponent 0 equals 1)

i¹ = i (any number with the exponent 1 is the number itself)

i² = -1 (this follows from the definition of the imaginary number, the square root of -1)

i³ = i² * i = -1 * i = -i

Now, the results start to repeat from 1 to -i:

i⁴= i² * i² = (-1) * (-1) = 1

i⁵ = i⁴ * i = 1 * i = i

i⁶ = i * i⁵ = i * i = i² = -1

i⁷ = i⁶ * i = -1 * i = -i

From that, we can follow the steps below to find the value of a power of i:

• divide the exponent by 4;

• if the rest of the division is 0, then the power equals ,i⁰ = 1,;

• if the rest of the division is 1, then the power equals ,i¹ = i,;

• if the rest of the division is 2, then the power equals ,i² = -1,;

• if the rest of the division is 3, then the power equals ,i³ = -i,.

So, for the power i⁶⁴⁹, the exponent is 649. Following the steps above, we find:

• 649/4, has a quotient of 162 and the, rest 1,. Therefore:

i⁶⁴⁹ = i¹ = i

Thus, i⁶⁴⁹ equals i.

7. Find the slope (m) between (5, 6) and (1, 0):

Slope (m) = (6 - 0)/(5 - 1) = 6/4

Slope (m) = 3/2

Find the y-intercept of the line, b, by substituting m = 3/2 and (x, y) = (1, 0) into y = mx + b:

0 = 3/2(1) + b

-3/2 = b

b = -3/2

To write the equation, substitute m = 3/2 and b = -3/2 into y = mx + b:

y = 3/2x - 3/2

-3 + 1/3 = b

So the hypothesis can be:  β = 0  (Null Hypothesis)  ,  β≠ 0 (Alternate Hypothesis)

If we consider a confidence level (the probability for which we can be confident that the null hypothesis is true) to be 95% (Probability = 0.95) then the level for which we are not confident that the null hypothesis is true will be (100 - 95)% = 5% (Probability = 0.05)

Thus, for this coefficient the P value is 0.5782.

As the p-value is more than the Probability for which we are not confident (0.05), so in this regard we can state then there is no such significance difference seen in this regard. Thus, we accept the null hypothesis here. This means that we can take the coefficient to be 0.
