X= ladies y = number of cats
<span>Each lady has 2 feet and each cat has 4 feet </span>
<span><=> </span>
<span>x + y = 26 (1) => number of characters </span>
<span>2x + 4y = 84 (2) => number of feet </span>
<span><=> operation : (1) * 2 </span>
<span>2x + 2y = 52 (1') </span>
<span>2x + 4y = 88 (2') </span>
<span><=> operation : (2') - (1') </span>
<span>2y = 26 </span>
<span><=> </span>
<span>y = 20 and x = 32- 16 = 16</span>
<span>10 ladies and 16 cats</span>
Answer:
Step-by-step explanation:
Constant rate of change is the slope.
<u>Find the slope using two points on the graph:</u>
<u>The slope is:</u>
Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
