A spinner has sections that are numbered 1 through 5. Melanie spins the spinner 15 times and
records her results in the dot plot.
Use the results to predict the number of times
the spinner will land on an even number in 300 trials
300 trials.

Answers

Answer 1

Answer:

160 times in 300 trials

Explanation:

Since the spinner has 5 sections numbered 1 through 5, there are 2 even numbers (2 and 4) and 3 odd numbers (1, 3, and 5).

From the given dot plot, we can see that Melanie landed on an even number 8 times out of 15 spins.

To predict the number of times the spinner will land on an even number in 300 trials, we can use proportion:

8/15 = x/300

Multiplying both sides by 300, we get:

x = 160

Therefore, we can predict that the spinner will land on an even number approximately 160 times in 300 trials.

The function g is defined by g(x) = 3x+4.

Find g(z+3).

I really need help with these Aleks assignments, can someone help me with them?

Answers

Answer:g(x) = (x+3)/(x2-4)

 

The domain refers to all of the x values that the function can take on.  In a rational expression like the one above, we have to be careful that the denominator is never 0, since division by 0 is undefined.  We can factor the denominator of g(x) as follows:

 

g(x) = (x+3)/((x+2)(x-2)

 

The denominator will be zero when x = 2 or -2.  Otherwise, g(x) is defined on all other values of x.  So the domain of g(x) is "x = all x not equal to -2 or 2".  In interval notation, the domain is:

 

(-∞,-2)U(-2,2)U(2,+∞)

 

On a number line, draw it as follows:

 

-∞ <======o=====o=======> +∞

                   -2            2

An account earns simple interest.

a. Find the interest earned.
$
b. Find the balance of the account.

Answers

Answer:

a) $300 in interest

b) $1800 account total

Step-by-step explanation:

Interest = Principal x Rate x Time

I = 1500(.04)(5)

I = 300

A = P + I

1800 = 1500 + 300

Select all that apply. Select the formulas that give the amount P in the account after the first period.

Answers

Options :

a.) P=1.005Po

b.) P=1.02Po

c.) P=Po(0.02/4)

d.) P=Po(4.02/4)

e.) P=Po(1+ 0.02/4)

Answer:

a.) P=1.005Po

d.) e.) P=Po(1+ 0.02/4)

Step-by-step explanation:

From the compound interest formula:

P = P0(1 + r/n)^t

Rate = 2% = 2/100 = 0.02

n = Number of compounding times per period, quarterly ; n = (12 /3) months

P = P0(1 + 0.02/4)^1

P = p0(1 + 0.02/4)

Simplifying further :

P = P0(1 + 0.005)

P = p0(1.005)

Answers

Step-by-step explanation:

To prove that two lines are perpendicular, when all we have are those two lines, we can use the Linear Pair Perpendicular Theorem - If two straight lines intersect at a point and form a linear pair of equal angles, they are perpendicular.

Our diagonals intersect at point O, so we'd need to show the two linear angles formed at that intersection point are equal, and we can do that with triangle congruency.

A rhombus is a parallelogram, so we will use what we already know about parallelograms - that the diagonals bisect each other.

It is then easy to show that the triangles  ΔAOD and  ΔAOB are congruent using the Side-Side-Side postulate, and from that that ∠AOD ≅ ∠AOB.

And now, since ∠AOD and ∠AOB are a linear pair, we use the Linear Pair Perpendicular Theorem - If two straight lines intersect at a point and form a linear pair of equal angles, they are perpendicular.

PROOF

(1) ABCD is a rhombus //Given

(2) AB=AD                     //definition of rhombus

(3) AO=AO                    //Common side, reflexive property of equality

(4) BO=OD // A rhombus is a parallelogram, a parallelogram's diagonals bisect each other

(5) △AOD≅△AOB   //Side-Side-Side postulate.    

(6) ∠AOD ≅ ∠AOB     //Corresponding angles in congruent triangles (CPCTC)

(7) AC⊥DB     //Linear Pair Perpendicular Theorem

The converse of this is also true: if a parallelogram's diagonals are perpendicular, it is a rhombus.

the point P = (x, -5/7) lies on the unit curcle shown below. What is the value of x in the simplest form?

Answers

Answer:

[tex]x =\± \frac{2\sqrt{6}}{7}[/tex]

Step-by-step explanation:

The question has missing details as the unit circle is not shown, However, I'll solve on a general terms.

Given

[tex]P = (x,-\frac{5}{7})[/tex]

Required

Determine the possible value of x

Since point p lies on the unit circle, we'll solve this question using the following unit circle formula:

[tex]x^2 + y^2 = 1[/tex]

Substitute -5/7 for y

[tex]x^2 + (-\frac{5}{7})^2 = 1[/tex]

[tex]x^2 + \frac{25}{49} = 1[/tex]

Collect Like Terms

[tex]x^2 =1- \frac{25}{49}[/tex]

Take LCM

[tex]x^2 =\frac{49 -25}{49}[/tex]

[tex]x^2 =\frac{24}{49}[/tex]

Take the square root of both sides

[tex]x =\± \sqrt{\frac{24}{49}}[/tex]

[tex]x = \±\frac{\sqrt{24}}{7}[/tex]

[tex]x = \±\frac{\sqrt{4*6}}{7}[/tex]

Split

[tex]x = \±\frac{\sqrt{4}*\sqrt{6}}{7}[/tex]

[tex]x =\± \frac{2*\sqrt{6}}{7}[/tex]

[tex]x =\± \frac{2\sqrt{6}}{7}[/tex]
