We can set up a proportion to solve this.  9 lions were tagged out of a sample of 50.  This gives us the ratio 9/50 for the first part of the proportion.

For the second ratio, we know 85 lions were tagged out of an unknown population; this gives us 85/x.

Our proportion is

9/50 = 85/x

Cross multiply:

9*x = 50*85

9x = 4250

Divide both sides by 9:

9x/9 = 4250/9

x = 472.222 

To the nearest whole number, this is 472 sea lions.

What tests are used to determine the radius of convergence of a power series? A. Divergence TestB. Root Test C. Comparison Test
REY [17]

Answer:

The radius of convergence is half of the length of the interval of convergence. If the radius of convergence is R then the interval of convergence will include the open interval: (a − R, a + R). To find the radius of convergence, R, you use the Ratio Test.

10.) Kelly is flying a kite to which the angle of elevation is
jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

sin70 =  \frac{h}{l}  \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

7. A scatter plot was created to show the relationship
Ksju [112]

Answer:

1020 students

Step-by-step explanation:

Given the trend line equation :

y = 0.1x + 18,

where y is the total number of staff members and x is the total number of students.

Using the equation, the predicted number of students in a school with 120 staffs ;

y = 120

y = 0.1x + 18

120 = 0.1x + 18

120 - 18 = 0.1x

102 = 0.1x

x = 102 / 0.1

= 1020 students
