Answer:

-2 < x < 4.5

Step-by-step explanation:

Step 1: Add 1 to all parts/sections.

  • -5+1
  • -4

Step 2: Divide all parts/sections by 2.

  • \frac{-4}{2}
  • -2 < x < 4.5

Therefore, the range of possible values of x is -2 < x < 4.5.

Ian is a phycologist interested in determining the proportion of algae samples from a local rivulet that belonged to a particula
pickupchik [31]

Answer: 16590

Step-by-step explanation:

The formula we use to find the sample size is given by :-

, where p = prior estimate of population proportion.

z^*= Critical z-value (Two- tailed)

E= Margin of error .

Let p be the population proportion of cyanobacteria.

Given : E = 0.01

Critical value for 99% confidence interval : z^*=2.576

If Ian does not want to rely on previous knowledge , then we assume p=0.5 because the largest standard error is at p=0.5.

Now, the required sample size = n=0.5(1-0.5)(\frac{2.576}{0.01})^2

n=0.25(257.6)^2=0.25(66357.76)=16589.44\approx16590

Required sample size = 16590

How do you figure these out?
I am Lyosha [343]
You do them in the order of operations, for example, on the 1st one you did 3x5 first and got 15, and then you added 2 and got a total of 17. On the second one, you did2x4 which is 8 and the you added 3 and made it a total of 11. So basically you do the last 2 boxes first, the add/subtract the first from the total of the other 2.

What is the value of x? <br> Enter your answer in the box. <br><br> (cm)
Taya2010 [7]

Answer:

x = 94 cm

Step-by-step explanation:

95.2 / 34 = 168/(x - 34)

95.2(x - 34) = 34 * 168

95.2x - 3236.8 = 5712

95.2x = 8948.8

       x = 94
