Beverly has a backyard that is square. One of the sides is 10 feet long. What is the area of her back yard?
Answers
Answer:
100 ft sq.
Step-by-step explanation:
A square means all sides are equal.
Area = bxh
10 ft x 10 ft = 100 ft sq.
Answer:
The area is 100 ft^2
Step-by-step explanation:
A square has 4 equal sides so if one side is ten then all of the sides are 10

The cubic regression function of the points (1,-1), (2,-13), (3,-45), (-1,11) is y = -2x³ + 2x² - 4x + 3
How to determine the function?
The points are given as:
(x,y) = (1,-1), (2,-13), (3,-45), (-1,11)
A cubic regression function is represented as:
y = ax³ + bx² + cx + d
Next, we determine the cubic function using a graphing calculator.
From the graphing calculator, we have the following coefficients:
- a = -2
- b = 2
- c = -4
- d = 3
Recall that:
y = ax³ + bx² + cx + d
So, we have:
y = -2x³ + 2x² - 4x + 3
Hence, the cubic regression function of the points is y = -2x³ + 2x² - 4x + 3

Step-by-step explanation:
Given : The probability that a bird will lay an egg =0.75
The probability that the egg will hatch =0.50
Now, the probability that the egg will lay an egg and hatch =
Also,The probability that the chick will be eaten by a snake before it fledges =0.20
Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80
Now, the probability that a parent will have progeny that survive to adulthood will be :-

would you get from £1
if you spent 77p?
Answers
You would get 23p as change from £1 if you spent 77p.
To find how much change you would get from £1 if you spent 77p, you need to subtract the amount you spent from the total amount you have.
Total amount = £1
Amount spent = 77p
To find the change, we need to convert both amounts to the same unit (pence) before performing the subtraction.
1 pound (£1) is equal to 100 pence, so:
Total amount = 100p
Amount spent = 77p
Now, subtract the amount spent from the total amount to find the change:
Change = Total amount - Amount spent
Change = 100p - 77p
Change = 23p
So, you would get 23p as change from £1 if you spent 77p.
