Answer:

x=40 y=16

Step-by-step explanation:

20x+50y=800 you can turn it into slope-intercept form and it would end up being y=-2/3x+16 so now you have your y intercept (16) and you know your rise and run -2(rise)3(run).

Or you can substitute a zero for x and solve for y

20(0)+50y=800 which equals 50y=800 which equals 16 y=16

then you substitute a zero for y and solve for x

20x+50(0)=800 which equals 20x=800 which equals 40 x=40

On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70

A study investigated about 3000 meals ordered from Chipotle restaurants using the online site Grubhub. Researchers calculated th

Allisa [31]

Answer:

21.186%

Step-by-step explanation:

z = (x-μ)/σ,

where

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

z = 2400 - 2000/500

z = 0.8

Probability value from Z-Table:

P(x<2400) = 0.78814

P(x>2400) = 1 - P(x<2400) = 0.21186

Converting to percentage:

0.21186 × 100

= 21.186%

Therefore, the percent of the meals

ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%

A bank features a savings account that has an annual percentage rate of 3.5% with interest compounded quarterly. Vanessa deposit

vazorg [7]

Answer:

APY = 0.04 or 4%

Step-by-step explanation:

Given the annual percentage rate of 3.5% that is compounded quarterly, and a principal of $6,500:

We can use the following formula to solve for the annual percentage yield (APY):

$APY = (1 + \frac{r}{n})^n - 1$

where <em>r</em> = interest rate = 3.5% or 0.035

<em> n</em> = number of compounding periods per year = 4

We can plug in the values into the equation:

$APY = (1 + \frac{r}{n})^n - 1$

$APY = (1 + \frac{.035}{4})^4 - 1$

$APY = (1 + 0.00875)^4 - 1$

$APY = (1.00875)^4 - 1$

APY = 1.03546 - 1

APY = 0.04 or 4%
