Answer:
<h2>2.3 < x < 8.7</h2>
Step-by-step explanation:
Look at the picture.
We have a = 5.5, b = x and c = 3.2.
Substitute:
(1)
5.5 + x > 3.2 <em>subtract 5.5 from both sides</em>
x > - 2.3
(2)
5.5 + 3.2 > x
8.7 > x
(3)
x + 3.2 > 5.5 <em>subtract 3.2 from both sides</em>
x > 2.3
From (1), (2) and (3) we have:
2.3 < x < 8.7
Answer:
Step-by-step explanation:
Probability of a head is 1/2 of getting heads.
probability of a number greater than 1 is 7/8 on 8 sided die
Total probability = 1/2 * 7/8 = 7/16 = 0.4375
Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500

Step-by-step explanation:
Given that 
, therefore, it follows that:
,
If the ratio of YW to XW = 2:1, therefore, 
Cross multiply to find XW
here is the solution.
Round the answer as needed.
