An annual percentage rate, or APR, is a figure that expresses the entire cost of borrowing money as a proportion of the loan's principle. An accurate picture of how much it costs to borrow money is intended to be provided by the APR on a loan or credit card.

Given

Mabel Causino has $35,000 to invest in a certificate of deposit for 4 years. The CD earns 4.75% interest

compounded daily.

1.048353

The table on page A14 shows the cost per $1.00 (over the course of a year).

$35,000×1.048353=$36,692.36

The sum of the initial principle and the amount per $1.00 is the amount (for a year).

$36,692.36−$35,000=$1,692.36

The difference between the amount (for one year) and the initial principal is the interest (for one year).

$1,692.36÷$35,000

=0.04835

=4.835%

The interest (for a year) divided by the initial principle results in the annual percentage yield.

The ratio of red marble to blue marble in a bag i 3:4. If there are 42 marble in the bag how many of the marble are red

Answers

The ratio of red marble to blue marble in a bag is 3:4. If there are 42 marble in the bag,There would be 30 red marbles in the bag.

Red and blue marbles are distributed in a 3:4 ratio.This means that for every 4 blue marbles, there are 3 red marbles.

If we divide 42 (the total number of marbles in the bag) by 4, we get 10.5. This tells us that if there are 4 blue marbles, there are 10.5 red marbles. We can't have a fraction of a marble, so we round down to 10.

Since for every 4 blue marbles there are 3 red marbles, if there are 10 blue marbles, there must be 10 x 3 = 30 red marbles.

Therefore, there are 30 red marbles in the bag.

what is the probability that the number of systems sold is within 1 standard deviation of its mean value?

Answers

The probability that now the number of sold will not deviate more than 1 standard deviation from the average is 0.74.

The given data is

x 1 2 3 4 5 6 7 8

p(x) 0.04 0.10 0.13 0.30 0.31 0.10 0.01 0.01

(a) calculate mean value of x:

μ = E(x)

  = ∑(xi.P(xi))

 = 4.13

(b)  calculate variance of x:

σ² = ∑(xi - E(x))².P(xi)

   = 1.81331

(c)  calculate standard deviation of x:

σ = √σ²

σ = √1.831

σ = 1.3539

The likelihood that the quantity of systems sold will be within one standard deviation of the its mean:

P(μ  - σ < x < μ  + σ ) = P(4.13 - 13539 < x < 4.13 + 1.3539)

                                = P(2.7761 < x < 5.4839)

                                = P(x = 3) + P(x = 4) + P(x = 5)

                                = 0.13 + 0.30 + 0.31

                                = 0.74

Casho has a points card for a movie theater. She receives 55 rewards points just for signing up. She earns 2.5 points for each visit to the movie theater. She needs at least 90 points for a free movie ticket. Use the drop-down menu below to write an inequality representing v, the number of visits she needs to make in order to get a free movie ticket.​

Answers

Answer: She need 14 visits to reach 90 points

Step-by-step explanation:

Let y be the number of points and v be the number of visits

We will have an equation

y= 2.5v + 55

Now we want to find the number of visits she needs to reach 90 points; we put 90 in the y.

90 = 2.5v +55

Subtracted 55 from both sides

35 = 2.5v

Divided both sides by 2.5

v= 14 visits

So she need 14 visits to reach 90 points

Answers

The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

What is the inequality equation?

Equations and inequalities are mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are supposed to be equal and shown by the symbol =. Whereas in inequality, the two expressions are not necessarily equal and are indicated by the symbols: >, <, ≤, or ≥.

To determine the minimum number of sets of glasses that Latanya should buy, we can set up the following inequality:

x * 6 + 390 >= 739

This inequality states that the number of glasses Latanya has after buying x sets of glasses should be greater than or equal to the minimum number of glasses the restaurant needs.

To solve for x, we can subtract 390 from both sides of the inequality to get:

x * 6 >= 739 - 390

x * 6 >= 349

x >= 349/6

x  >= 58.16

x >= 58

Hence, The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

What is the equation of the line that passes through the point (8, 6) and has a slope
of o?

Answers

Answer:

y=6

Step-by-step explanation:

The equation of a line in slope-intercept form is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis. In this case, we are given that the line passes through the point (8, 6) and has a slope of 0, so we can plug these values into the equation to find the equation of the line.

Since the slope of the line is 0, the equation of the line becomes:

y = 0x + b

To find the value of b, we need to plug in the coordinates of the point (8, 6) into the equation and solve for b. This gives us:

6 = 0 * 8 + b

b = 6

Therefore, the equation of the line is given by:

y = 0x + 6

This equation tells us that the y-coordinate of any point on the line is always 6, regardless of the x-coordinate of the point. This means that the line is horizontal and passes through the point (8, 6).

Since, we know that, when rotating a point 270° counterclockwise about the origin, the point (x,y) becomes (y,-x) which means we switch the places of x and y coordinates and make x as negative.

Therefore, the transformation is given by

(x ,y) -> ( y , -x)

The rate of change of the given data between 3 and 7 hours is; 19 miles per hour

How to calculate the rate of change?

We are told that rate of change is the difference between what the value of the data began at versus the value the data ended at.

Now, the formula for the rate of change between two coordinates (x₁, y₁) and (x₂, y₂) is;

Rate of change = (y₂ - y₁)/(x₂ - x₁)

Now, we are told that we should find the rate of change from 3 to 7 hours and so we first write the coordinates;

(3, 209) and (7, 285)

Thus;

Rate of change = (285 - 209)/(7 - 3)

Answers

Answer:

  500

Step-by-step explanation:

You want to know the rate in 4 years if it is 380 units per day, and increasing by 30 units per day per year.

Rate

The rate in 4 years will be the sum of the current rate and the amount of increase. The amount of increase is the rate of increase, multiplied by time:

  amount of increase = (30 units/day)/year × (4 years) = 120 units/day

Then the rate in 4 years will be ...

  new rate = current rate + increase

  new rate = 380 units/day + 120 units/day = 500 units/day

The company will be producing 500 units per day in 4 years.

Answers

Answer:

The possible values of t for which the rocket's height is 12 meters are approximately 1.1 or -1.1.

Step-by-step explanation:

The height of the rocket after t seconds is given by the equation
h = 35t - 5t^2.To find the values of t for which the rocket's height is 12 meters, we can set the height equal to 12 and solve for t

12 = 35t - 5t^2

To solve this quadratic equation, we can use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation. In this case, a = -5, b = 35, and c = -12.Plugging these values into the quadratic formula, we get

t = (35 ± √(35^2 - 4(-5)(-12))) / 2(-5)

t = (35 ± √(35^2 + 240)) / -10

t = (35 ± √575) / -10

This gives us two possible values for

t = (35 + √575) / -10 = (35 + 24) / -10 = 11/10 = 1.1

t = (35 - √575) / -10 = (35 - 24) / -10 = -11/10 = -1.1

Therefore, the rocket's height is 12 meters when t is approximately 1.1 or -1.1.

The rocket's height is 12 meters at time t = 0.4 seconds.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

A model rocket is launched with an initial upward velocity of 35 m/s.

The rocket's height h (in meters) after t seconds is h=35t-5t

We have to find the time(s) when the rocket's height is 12 meters, we need to solve the equation:

h = 35t - 5t = 30t

We want to find all values of t that make h = 12. So we set h = 12 and solve for t:

12 = 30t

Divide both sides by 30

t = 12/30

t = 0.4

Therefore, the rocket's height is 12 meters at time t = 0.4 seconds.

Answers

Julia needs to spend 1.92 hours exercising on Sunday in order to reach her goal.

The number of hours Julia needs to spend exercising on Sunday can be calculated as follows;

Total number of hours to spend exercising = 5 1/4 = 21/4 = 5.25 hours

Total number of hours spent exercising on Saturday = 3 1/3 = 10/3 = 3.33 hours

Now the number of hours she needs to spend exercising on Sunday can be determined by subtraction as follows;

Hours on Sunday = Total hours - Hours on Saturday

Hours on Sunday = 5.25 hours - 3.33 hours

Hours on Sunday = 1.92 Hours
