We are again studying the times required to solve two elementary math problems. Suppose we ask four students to attempt both Pro

KiRa [710]

Answer:

(-16.494 ; -3.506)

Step-by-step explanation:

student Prob A Prob B difference, d (A-B)

1 20 35____ - 15

2 30 40 ___ - 10

3 15 20 ___ - 5

4 40 50 __ - 10

Difference, d = -15, -10, -5, -10

Xd = Σd/ n = - 40 / 4 = - 10

Standard deviation of d ; Sd = 4.082

The confidence interval for the difference is given as :

Xd ± Tcritical*(Sd/√n)

Tcritical at 95%; df = n - 1 ; 4 - 1 = 3

Tcritical(0.05, 3)). = 3.182

C.I = -10 ± 3.182(4.082/√4)

C.I = -10 ± 6.494462

C. I = (-16.494 ; -3.506)

Use the following information to answer the question that follows:

sveticcg [70]

Option E is correct. The amount Mayra deposited into the account quarterly is $1,146.35 where the value of n is 4

In order to get the amount compounded quarterly, we will use the compounded interest formula as shown:

A = P(1+r/n)^nt where:

A is the amount after 5 years = $6000

r is the rate (in %) = 6% = 0.06

n is the compounding time = 1/4 (quarterly)

t is the time taken (in years) = 5 years

Required

Amount invested quarterly.

First, we need to get the amount initially invested

Substitute the given values into the formula;

6000 = P(1+0.06(4))^{5/4)}

6000 = P(1+0.24)^1.25

6000 = P (1.24)^1.25

6000 = 1.3085P

P = 6000/1.3085

P = $4,585.40

The amount initially deposited will be $4,585.40

The amount deposited quarterly = P/n where n = 4

Amount deposited quarterly = $4,585.40/4

Amount deposited quarterly = $1,146.35

Therefore the amount Mayra deposited into the account quarterly is $1,146.35 where the value of n is 4.

Sergio [31]

The number of times that the shape will map back onto itself as the shape rotates 360° about its center is 6.

<h3>What is the sum of all the exterior angles of a regular polygon?</h3>

For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).

Regular polygons have all sides the same and that apothem bisects the side in two parts, (provable by symmetry).

A regular polygon with n sides can map onto itself by n times

It will rotate 360°/n about its center every time and will map onto itself

Examples are in the attached table as well as the solution.

The number of times that the shape will map back onto itself as the shape rotates 360° about its center is 6.

Which problem can be solved using this equation? 2x + 8 = 15? A) Maria bought a notebook for $8 and a magazine. What was the tot

rjkz [21]

Answer:

C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook?

Step-by-step explanation:

The equation has twice an unknown value added to 8 with the result being 15.

<em>Here are how the answer choices compare to the equation:</em>

A) only one magazine of unknown cost is involved, not two. There is not enough information to answer this question with any equation.

B) three unknowns are involved and the question asks for the difference of their sum and 15. There is not enough information to answer this question with any equation.

C) if x represents the cost of the notebook, the equation is appropropriate to finding its cost, as asked by the question. This is the best choice.

D) only one unknown. The question makes no sense, as she bought items worth more than the amount paid.
