5 0

Answer: for -4/3x+4 the y intercept is (0,4) and x is (3,0) the slope is -4/3

for 2/7x+2 the y intercept is (0,2) and the x is (-7,0) the slope is 2/7

Answer:

With a .95 probability, the margin of error is = 0.392

Step-by-step explanation:

Given -

In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for a sample of 81 business students over a one-week period.

Sample size ( n ) =81

Standard deviation $(\sigma )$ = 1.8 hours

$\alpha$ = 1 -.95 =.05

$Z_{\frac{\alpha }{2}}$ = $Z_{\frac{.05 }{2}}$ = 1.96 (Using Z table)

With a .95 probability, the margin of error is

Margin of error = $Z_{\frac{\alpha }{2}}\frac{\sigma }{\sqrt{n}}$

= $Z_{\frac{.05 }{2}} \frac{1.8 }{\sqrt{81}}$

= $1.96\times 0.2$

Margin of error = 0.392

Answer:

$3 \frac{3}{4}$

Step-by-step explanation:

$\frac{3}{4} \div \frac{1}{5} \\ \\ = \frac{3}{4} \times \frac{5}{1} \\ \\ = \frac{3 \times 5}{4 \times 1} \\ \\ = \frac{15}{4} \\ \\ = 3 \frac{3}{4}$
