Answer:

It's long but you use Substitution!

Step-by-step explanation:

Let's solve your system by substitution.

2x+3y=3750;4x+y=4250

Rewrite equations:

4x+y=4250;2x+3y=3750

Step: Solve 4x+y=4250 for y:

4x+y = 4250

4x+y+−4x = 4250+−4x (Add -4x to both sides)

y = −4x+4250

Step: Substitute −4x+4250 for y in 2x+3y = 3750:

2x+3y=3750

2x+3(−4x+4250)=3750

−10x+12750=3750 (Simplify both sides of the equation)

−10x+12750+−12750=3750+−12750 (Add -12750 to both sides)

−10x =−9000

−10x = −9000 (Divide both sides by -10)

−10          −10

x=900

Step: Substitute 900 for x in y = −4x+4250:

y=−4x+4250

y=(−4)(900)+4250

y=650 (Simplify both sides of the equation)

Answer:

x=900 and y=650

Step-by-step explanation:

The probability of this happening would be a 1 when placing a value between zero and one inclusive. One in this case would indicate a 100% probability. This is the case because in the question it is stated that it is "certain" that you will get 2 kings when selecting 50 cards, this means that no matter what it will happen every time 50 cards are drawn, thus making the probability 100%. If the question were phrased differently such as "what is the probability of getting 2 kings from 50 cards drawn?" then the probability would be 0.04 or 4% which is 2/50.

Using probability concepts, it is found that the likelihood is of 1.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

A few observations regarding probabilities are important.

In this problem, you are certain to get 2 Kings when selecting 50 cards from a shuffled deck, hence the likelihood is of 1.

Answer: 4224 feet cubed

Step-by-step explanation:

Volume for a rectangular tank =LxWxH

22x12x16=4,224

Answer:

4224in^3

Step-by-step explanation:

The formula for volume is height x length x width ( x means multiply)

so to find the volume of the fish tank you multiply each of the sides by each other, 12x16x22. So the volume of the fishtank is 4224 inches cubed(^3) make sure you write the cubed and units at the end, just like how for area you always make it squared.

Answer:

Step-by-step explanation:

The length of a side can be found using the distance formula:

  d = √((x2 -x1)^2 +(y2 -y2)^2)

For P1P2, this gives ...

  d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8

  P1P2 = 2√2

__

The same ∆x and ∆y apply to P1P3, so we know ...

  P1P3 = 2√2

__

The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.

__

The length of P2P3 can be found by subtracting the y-coordinates:

  P2P3 = 1 -(-3)

  P2P3 = 4

__

We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.

36+x>=50

I might be wrong but here's my explanation.

Step-by-step explanation:

We first of all know that she MUST sell 50 or more baskets.

Knowing this, we know the inequality sign will be facing the x and the 36 as the baskets can be equal to 50 or greater than 50.

Now we have: 36+x>=50

The x is remaining baskets needed.

If you were to solve the inequality you would get x>=14

Hope this helps! P.s. I'd do a bit more research just in case I'm wrong!! :)

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

Answer:

a) 0.11277

b) 0.83253

c) 0.67364

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

From the question,

Mean = $109.55.

Standard deviation = $21.00.

a) What proportion of bills are greater than $135?

z = (x-μ)/σ

z = 135 - 109.55/21

= 1.2119

Probability value from Z-Table:

P(x<135) = 0.88723

P(x>135) = 1 - P(x<135) = 0.11277

The proportion of bills are greater than $135 = 0.11277

(b) What proportion of bills are between $84 and $143?

For x = $84

z = (x-μ)/σ

z = 84 - 109.55/21

= -1.21667

Probability value from Z-Table:

P(x = 84) = 0.11187

For x = 143

z = (x-μ)/σ

z = 143 - 109.55/21

= 1.59286

Probability value from Z-Table:

P(x = 143) = 0.9444

The proportion of bills are between $84 and $143

= P(x = $143) - P(x = 84)

= 0.9444 - 0.11187

= 0.83253

(c) What is the probability that a randomly selected household had a monthly bill less than $119?

For x = $119

=119 - 109.55/ 21

= 0.45

Probability value from Z-Table:

P(x<119) = 0.67364

The probability that a randomly selected household had a monthly bill less than $119 is 0.67364

Answer:

[tex]b=-3[/tex]

Step-by-step explanation:

We have:

[tex]25^b\cdot 125^{b+2}=125^b[/tex]

Notice that 125 is the same as 5³. So:

[tex]25^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]

Also, 25 is the same as 5². So:

[tex]((5)^2)^b\cdot ((5)^3)^{b+2}=((5)^3)^b[/tex]

Power of a power property:

[tex]5^{2b}\cdot 5^{3(b+2)}=5^{3b}[/tex]

Power of a product property:

[tex]5^{2b+3(b+2)}=5^{3b}[/tex]

Since they have the same base, the exponents are equal. So:

[tex]2b+3(b+2)=3b[/tex]

Solve for b. Distribute on the left:

[tex]2b+3b+6=3b[/tex]

Combine like terms on the left:

[tex]5b+6=3b[/tex]

Subtract 5b from both sides:

[tex]6=-2b[/tex]

Divide both sides by -2. So, the value of b is:

[tex]b=-3[/tex]

And we're done!

Step-by-step explanation:

as a percentage, 0.95 is 95%. 835% is greater than 95%. hope this helps.

Answer:

No

Step-by-step explanation:

835% as a decimal would be 8.35 and 0.95 is what you are comparing it to, so you could look at it's whole number and you see that it is bigger than zero so it is indubitably more than 0.95.

8.1% is the exact interest rate

The exact rate of interest is 8.11%.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Given:

Arianna North borrowed $12,500

She agreed to pay back $13,250 in 270 days.

let x be the interest rate was she paying

x= 13250 - 12500

= 750

So, x= 750/ 12500 (270/ 365)

x% = 750/ 9,246.57

x% = 0.0811

x%= 8.11%

Hence, the exact rate of interest is 8.11%.
