Answers

Answer:

X=3 y = 5

Step-by-step explanation:

Step 1) Solve the first equation for  y

Step 2) Substitute  3 x − 4  for  y  in the second equation and solve for  x

Step 3) Substitute  3  for  x  in the solution to the first equation at the end of Step 1 and calculate  y

The solution is:  

x = 3  and  y = 5  or  ( 3 , 5 )

You roll a fair six-sided die. The die shows an even number or a number greater than four .


Solve it (NOT MULTIPLE CHOICE) find the probability:)

Answers

Answer:

4/6

Step-by-step explanation:

There are 3 ways to get an even number: 2, 4, 6 -> chance is 3/6=1/2

There is 1 way to get a number greater than 4:  5 (because 6 was already counted) -> chance is 1/6

Add up the probabilities: 1/2 + 1/6 = 3/6 + 1/6 = 4/6

The probability of rolling an even number or a number greater than 4 is 4/6

Step-by-step explanation:

1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

3. A proportional relationship must pass through the origin in order to be a proportional relationship.

4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.

5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

En una tienda se anuncia la rebaja de 20% en todos sus artículos . Rafael elije una camisa y al llegar a la caja le informan que sea camisa , por traer etiqueta roja . Cuenta con un descuento adicional de 15% . Si Rafael pago $510.00 , cuál era el precio de la camisa sin los dos descuentos

Answers

Responder:

$ 750

Explicación paso a paso:

Dado que :

Descuento en todos los artículos = 20%

Descuento adicional dado = 15%

Monto final pagado por la camisa = $ 510

Precio de la camiseta sin descuento:

Sea el precio inicial de la camisa = x

Primer descuento obtenido = 20%

Precio pagado después de un descuento adicional del 15%

Primer descuento:

(1 - 0,20) * x = 0,8x

Segundo descuento:

(1 - 0,15) * 0,8x = 510

0,85 * 0,8x = 510

0,68x = 510

x = 510 / 0,68

x = $ 750

Tiana compares the length of a name on a nameplate to the number of letters in the name. She draws the scatterplot below, and then she plots and determines an equation for the trend line. Nameplates A graph has letters on the x-axis and length (inches) on the y-axis. A trend line goes through points (2, 5) and (4, 8). The regression equation is y = 1.47 x + 2.05. Based on the information above, which is the best estimate of the number of letters that a name contains if the nameplate is 6 inches long? 3 4 10 12

Answers

Answer:

3

Step-by-step explanation:

The best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

What is a scatter plot?

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

It is given that, the regression equation is y = 1.47 x + 2.05.

The name's letter count is represented by variable x, whereas the name's length on a nameplate is represented by variable y.

The nameplate is 6 inches long, so y=6 and you can find x by doing the following:

6=1.4x+2.05

1.4x=6-2.05

1.4x=3.95

x=2.69

x≈3

Thus, the best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.

Klein opened a savings account that paid 5% simple interest with 6,000 in principal. If Klem left that money untouched in the account for ten years,then how much interest with he have earned?

Answers

Answer:

I= $3,000

Step-by-step explanation:

Giving the following information:

Klein opened a savings account that paid 5% simple interest with 6,000 in principal.

Number of periods= 10 years

To calculate the interest earned, we need to use the following formula:

I= P*r*t

P= principal

r= interest rate

t= time

I= 6,000*0.05*10

I= $3,000

Two cards are drawn from a pack of 52 cards one by one without replacement; that is, the first card is not replaced before the second card is drawn. What is the probability of the second card being a king of spades if the first card is a king of club

Answers

Answer:

The probability is 1/51

Step-by-step explanation:

In a deck of cards, there are 52 cards

one king of spades and one king of club

If the first is a king of club, after drawing it, the number of cards that we will have left will be 52-1 = 51 cards

So the probability that the second is a king of spades is the number of king of spades/number of remaining cards

Mathematically that will be 1/51
