Step-by-step explanation:
High in the Rocky Mountains, a biology research team has drained a lake to get rid of all fish. After the lake was refilled, they stocked it with an endangered species of Greenback trout. Of the 2000 Greenback trout put into the lake 400 were tagged for later study. An electroshock method is used on individual fish to get a study sample. However, this method is hard on the fish. The research team wants to know the smallest number of fish that must be electroshocked to be at least 50% sure of getting a sample of two or more tagged trout.
we have to find out smallest number fish (n) that must be electroshoked to be atleast 50% &
species of Greenback trout of the 2000 greenback trout put into the lake 400

Home Depot is delivering washing machines to buyers. The washing machines are rectangular prisms that measure 5 ft x 5 ft x 6 ft. These machines are then packed into a delivery truck with dimensions of 30 ft x 15 ft x 12½ ft.
What is the volume of the delivery truck? please show work
How many washing machines can be packed into the delivery truck? show work please
Answer:
37.5
Step-by-step explanation:
Volume of the washing machine = 5 ft x 5 ft x 6 ft
= 150 ft³
Volume of the delivery truck = 30 ft x 15 ft x 12½ ft
= 5,625 ft³
How many washing machines can be packed into the delivery truck?
Number of washing machine in the truck = Volume of the delivery truck / Volume of the washing machine
= 5,625 ft³ / 150 ft³
= 37 1/2
Or
= 37.5

Heather made $209 for 11 hours of work.
At the same rate, how many hours would she have to work to make $171?
Answer:
9 hours

1 hour = 19 dollars
To get from 19 to 171 multiply by 9.
9 hours: 171 dollars.
She has to work 9 hours.
I hope this helps :)
Answer:
9 hours
Step-by-step explanation:
rate: $209/h11 = $19 per 1 hour
How many hours?: 171/19 = 9 hours

a store offers a discount of 40 off any one regular-priced item. employees also get 10% off any purchases. in which order should the discounts apply so that the employee pays the least amount?
A. Employee discount then store discount
B. They are both the same
C. Store discount then employee discount
Let's say the price of an item is $1
Scenario #1 - 40% off $1 = 40 cents OFF
The discounted price = 60 cents
Now the 10% off of 60 cents
60-6 = 54 cents.
Scenario #2 - 10% of $1
The discounted price = 10 cents
100(cents) - 10 = 90 cents
Now the 40% off of 90 cents
90-36 = 54 cents
Let's try another value to confirm
Let's say the price of an item is $2
Scenario #1 - 40% off $2 = 80 cents OFF
200-80= 120 = $1.20
Now the 10% off of $1.20
120-12= 108 = $1.08
Scenario #2 - 10% off $2 = 20 cents OFF
200-20 = 180= 1.80
Now the 40% off of $1.80
180-72 = 108 = 1.08
With these two examples we can confirm either order
will give you the same savings.
Answer:
B. They are both the same

Answer:
1/48
Step-by-step explanation:
For the left spinner, there are 8 equal slots and one of which is 6. The probabililty of landing on just six would be 1/8.
For the right spinner, there are 6 equal slots and one of which is C. The probability of landing on just C would be 1/6.
Now when we try to get to spin both of them at the same time we need to multiply the probabilities of both:
1/8*1/6=1/48
Hope this helps!
Answer:
Step-by-step explanation:
the probability is 1/48 because
to get a number 6 is a 1/8 percent chance.
the get the letter C is a 1/6 percent chance
you multiply 1/6 and 1/8 to get the probability of 1/48

Do the following side lengths form a triangle?
3.4, 6.6, 10
A.Yes
B.No
Answer:
B.NoStep-by-step explanation:
Because,
According to Triangle Inequality Property:
Measurement of any two sides of a triangle is always greater than the third side.
But here,
(3.4 + 6.6 ) i.e. 10 = 10
Hence,
These side lengths can't form a triangle.

Beak Depth
A graph here shows the average frequency of beak depth for a species of birds in an area. There is a higher frequency of intermediate
beak depths, with some variation within the population for beak size.
A homeowner removes the native landscaping that contained trees and shrubs that formed fruits and nuts. The homeowner plants
new trees that produce only larger sized nuts. No more smaller berries or intermediate fruit food sources are available
What is the most likely impact of the change in the food supply within the homeowner's vicinity? Select ALL that apply.
A)
B)
There will be a decrease in frequency for beak sizes labeled at point 2 on
the graph
Natural selection will likely favor an increase in frequency for beak sizes at
point 3 on the graph
Individual birds will migrate to the area, increasing the frequency of beak
sizes at point 1 on the graph.
The population of birds will change over time with regard to its beak
frequency due to directional selection
The population of birds will change over time with regard to its beak
frequency due to stabilizing selection,
