In which quadrants do solutions for the inequality y is less than or equal to two sevenths times x plus 1 exist?
hram777 [196]

Answer:

y will be in every single quadrant

Step-by-step explanation:

So we have the equation y\leq \frac{2}{7} x+1  first we will have to look at the equation. It says that y is less than or equal to \frac{2}{7} x+1 since y is less than \frac{2}{7} x+1 the only place the shaded area where y can be is under the line that is drawn be the equation. When the equation is graphed the y-intercept will be on positive 1 it since slope is rise over run it will look something like the file attached to this. so under the line you can see every single quadrant so that is why it would be that way

Logan took out $23,400 in student loans to attend college at a compound interest rate of 5%. He deferred payments for two years.
blagie [28]

Answer:

$25,740

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 23400 × 0.05 × 2 = 2340

I = $ 2,340.00

The simple interest accumulated

on a principal of $ 23,400.00

at a rate of 5% per year

for 2 years is $ 2,340.00.

Dimas [21]

Answer:

Confidence interval @ 90% = [0.5324 < p < 0.5656]

Step-by-step explanation:

We are given the following information:

Sample size (n) = 2430

Proportion of win (p) = 0.549

Proportion of loss (q) => 1-p = 0.451

By formula of confidence interval,

CI = p ± Z(90%) * \sqrt{\frac{p*(1-p)}{n}} ,

CI = 0.549±(1.645* ((0.549*(0.451))/2430))^(0.5)

CI = [0.5324 < p < 0.5656]
