Answer:

720 individuals

Step-by-step explanation:

According to my research, I can say that based on the information provided within the question you can conclude that the population of land snails has about 720 individuals. We can calculate this by using the Rule of Three formula that is attached below.

 x   ⇒   80 marked

45   ⇒   5 marked

\frac{45*80}{5} = x

720= x

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

4vir4ik [10]

Answer:

you bought a little bit less than you needed

Step-by-step explanation:

so if it takes 7 yards to make three jackets and you have 15 yards this is what you have to do:

7 yards=3 jackets

7+7=14 so with 14 yards you can make 6 jackets

but you bought fifteen and 7 divided 3 equals 2.3 ( or what it takes to make one jacket)

so if you wanted to have exactly enough material to make 7 jackets you need  16.3 yards

Suppose that a jewelry store tracked the amount of emeralds they sold each week to more accurately estimate how many emeralds to
Ratling [72]

Answer: point estimate = 3.88

Margin of error = 0.63

Step-by-step explanation:

Confidence interval is written in the form,

(Point estimate - margin of error, Point estimate + margin of error)

The sample mean, x is the point estimate for the population mean. Let m represent the margin of error. Since the confidence interval is given as (3.25 , 4.51), it means that

x - m = 3.25

x + m = 4.51

Adding both equations, it becomes

2x = 7.76

x = 7.76/2

x = 3.88

Substituting x = 3.88 into x + m = 4.51, it becomes

3.88 + m = 4.51

m = 4.51 - 3.88

m = 0.63

A = (P/4)(P/2 - P/4)
= (P/4)^2

Therefore it is a square
Playground
256 yd^2
P least perimeter 

256 = (P/4)^2
P/4 = √256
= 16
P = 4*16
= 64

The least fencing is 64 yards.

An image of a parabolic lens is projected onto a graph.The y-intercept of the graph is (0, 90), and the zeros are 5 and 9. Which
Gnesinka [82]

Step-by-step explanation:

If the zeros are 5 and 9, then the equation will have the form:

y = a (x–5) (x–9)

We know the point (0, 90) is on the curve, so we can use this to find the coefficient a:

90 = a (0–5) (0–9)

90 = 45a

a = 2

y = 2 (x – 5) (x – 9)
