Answer:
It think this should be the complete question: Laws have been instituted in Florida to help save the manatee.To establish the number of manatees in Florida, 150 manatees were tagged. A new sample was taken later, and among the 40 manatees in the sample, 3 were tagged. Approximate the number of manatees in Florida.
The approximate number of manatees in Florida is 2,000
Step-by-step explanation:
To solve this problem, we will use the formula
N= (C*R)/M
Where N is the toal estimated population
C is the total first capture
R is the total recapture after the first
M is the total tagged from recapture
Thus, we have:
N = (150*40)/3
N = 6000/3
N= 2,000
So, the approximate manatee is .
Ratio and Proportion are explained majorly based on fractions. When a fraction is represented in the form of , then it is a ratio whereas a proportion states that two ratios are equal. Here, a and b are any two integers. The ratio and proportion are the two important concepts, and it is the foundation to understand the various concepts in mathematics as well as in science. the proportion is represented by,
.
Let us assume represents the unknown observed manatee, which is actually total manatees so the proportion is,.
Now, cross multiplying the given proportion as,

Step-by-step explanation:
Answer:
the answered would be 8.8444444
Answer:
the slope is 4 and the y intercept is (0,-3)
Step-by-step explanation:
When working with this its best to remember y=mx+b, the slope will always be in front of the X. so for example 7x+y=5 ( not a real problem ) but the slope would be 7 because its in front of the X.
Answer:
Step-by-step explanation:
The first thing to notice is that the diamond is just a square rotated 45 degrees square, with 90 feet sides, so the total area of the diamond is:
A(square)= l x l = 90 ft * 90 ft = 8100
We also need to calculate the area of the mound, assuming it being a circle:
A(circle)= And r=diameter/2= 18 ft/2 = 9 ft
A(circle) = = 81
Now since the ball has an equal chance of bouncing anywhere in the field, the probability would be the ratio of the area occupied by the mound inside of the diamond.

Answer:
y = {1, 3, 7}
Step-by-step explanation:
Given
y = ½x + 3
Domain: {-4, 0, 8}
Required
Determine the range of the function
To do this, we simply substitute each value of the domain in the given expression
We start with the first
Substitute -4 for x in y = ½x + 3
y = ½ * -4 + 3
y = -2 + 3
y = 1
Then 0
Substitute 0 for x in y = ½x + 3
y = ½ * 0 + 3
y = 0 + 3
y = 3
Lastly, 8
Substitute 8 for x in y = ½x + 3
y = ½ * 8 + 3
y = 4 + 3
y = 7
Hence, the range of the function is:
y = {1, 3, 7}
Answer:1,3,7
Step-by-step explanation:
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
