Answer:

The rate of simple interest for loan was 8%

Step-by-step explanation:

Given

Principal amount = p = $6200

Time = t = 1 year

Amount after interest = $6696

We have to calculate the amount of interest first

So,

Interest amount =I= Amount after interest - principal amount

= 6696-6200

=$496

The formula for simple interest is:

The equation of the line is y= -2/5x+156/5

Step-by-step explanation:

y=mx+b

m= -2/5 ( 23,22)

y-y=m(x-x¹)

y-22=-2/5(x-23)

y-22=-2/5x+46/5

y= -2/5x+156/5

Answer:

Solved using binomial, probability = 5.7%

Step-by-step explanation:

Number of people (N) = 7

Probability of success (using phone) = 63% = 0.63

So, probability of failure (not using phone) = 1 - 0.63 = 37

Number of success (r) = 2

N c r . P^r . Q^n-r

7 c 2 (0.63)^2 (0.37)^5

= 21 (0.3969) (0.0069)

= 0.057

Answer:

Thus, the rule of a point P(x, y) reflected over the line y = -x

P(x, y) → P'(-y, -x)

we conclude that:

Step-by-step explanation:

We know that If a point P(x, y) is reflected over the line y = -x, the x-coordinate and y-coordinate tend to change places and the signs are reverses.

Thus, the rule of a point P(x, y) reflected over the line y = -x

P(x, y) → P'(-y, -x)

Thus, we conclude that:

Answer:

ANY line that has a slope of 3, and any y intercept other than -5.

Step-by-step explanation:

Parallel lines have the same slopes, but different y intercepts.

So, it would be ANY line that has a slope of 3, and any y intercept other than -5.

Answer:

1238.9

Step-by-step explanation:

The volume of pyramid with square a square base is 1239 [tex]inch^{3}[/tex]

A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid

We have

Side length of base(L) = 14.7 inch

Height of pyramid(H) = 17.2 inch

Given ,Base is a square then

length=width(w)=14.7 inch

We know the formula of volume of pyramid = 1/3(L×W×H)

                                                                         = 1/3 (14.7 × 14.7 × 17.2)

                                                                         = 1/3 × 3716.748

                                                                         = 1238.916

                                                                        = 1239 [tex]inch^{3}[/tex]

Hence, The volume of pyramid is 1239 [tex]inch^{3}[/tex]

Answer:

D

Step-by-step explanation:

Proportional relationships come in the form

[tex]y=kx[/tex]

and [tex]k[/tex] is the constant of proportionality. By comparing the general case [tex]y=kx[/tex] and your specific case [tex]y=12x[/tex], you can see that in your case [tex]k=12[/tex].

In the equation y = 12x the constant of proportionality is D. 12.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Let y = kx.

∴ k = y/x.

Given, y = 12x.

12 = y/x.

So, the constant of proportionality is 12.
