Answer:
1. 2.9>2.9 False
2. 4.5≥4.5 True
3. 6≤−6 False
4. -3<3 True
Step-by-step explanation:
1. 2.9>2.9 is false becuase those 2 numbers are equal
2. 4.5≥4.5 is true because they are both equal, and the sign said less than or EQUAL to
3. 6≤−6 is false becuase 6 is greater than -6
4. -3<3 is true becuase -3 is less than 3
to more fully understand, you should look at a number line

Step-by-step explanation:
Answer: 0.9577
Step-by-step explanation:
Formula for margin of error (E):
, where p = sample proportion, n =sample space, z* critical z-value.
Given: n= 200
Critical value for 97% confidence level = 2.17
Margin of error (E) =
Hence, the margin of error for a 97% confidence interval = 0.9577
Answer:
<em>x - 5y = - 10 </em>
Step-by-step explanation:
y = mx + b (b is y-intercept)
m =
~~~~~~~~~~~~
x + 4y = 8 ⇔ y = x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are <u><em>(0, 2)</em></u>
(5, 3)
m = =
y = x + 2 (slope-intercept form)
<em>x - 5y = - 10</em> (standard form)
