The factors of the quadratic equation x²- 5x + 4 are (x - 4)(x - 1) option (A) is correct.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
We have a quadratic equation:
= x²- 5x + 4
= x² -x - 4x + 4
= x(x - 1) - 4(x - 1)
= (x - 4)(x - 1)
Thus, the factors of the quadratic equation x²- 5x + 4 are (x - 4)(x - 1) option (A) is correct.

Suppose the sample space for a continuous random variable is 0 to 8. If the area under the density curve for the variable from 0 to 5 is 0.625, what is the area under the density curve from 5 to 8?
========================================================
Explanation:
The portion from x = 0 to x = 5 has area 0.625, so 62.5% of the total area is accounted for. The remaining 100% - 62.5% = 37.5% of the total area must be in the remaining portion from x = 5 to x = 8. Convert 37.5% to decimal form to get the answer 0.375
-----------------
Another approach
We have two disjoint areas under a curve. The two areas must add to 1. Let A be the unknown area
So,
0.625+A = 1
A = 1-0.625
A = 0.375
The area under the curve from x = 5 to x = 8 is 0.375

An empty bathtub is filled at a constant rate of 8 gallons per minute. The bathtub will hold 36
gallons of water when full. The volume. V. of water in the bathtub is a function of t. the time
in minutes.
Which is the best description for the domain of the function V?
Answer:
0 ≤ t ≤ 4.5.
Step-by-step explanation:
Since the volume of the tub, V is increasing at a rate of 8 gallons per minute, the volume of the bathtub at any time, t is V = 8t.
Now, to find the domain of the function, V, we know that the minimum value for V is zero and the maximum value is 36. Now, at V = 0,
V = 8t
0 = 8t
t = 0 and at V = 36 gallons,
V = 8t
36 = 8t
t = 36/8
t = 4.5 minutes
Since 0 ≤ V ≤ 36, 0 ≤ t ≤ 4.5.
So, the domain of the function V is 0 ≤ t ≤ 4.5.

An oil company conducts a geological study that indicates that an exploratory oil well should have a 20% chance of striking oil.
A. What is the probability that the first strike comes on the third well drilled?
B. What is the probability that the third strike comes on the seventh well drilled?C. What is the mean and the variance of the number of bad wells, if the oil company wants toset up three producing wells?
Answer:
a) 0.128
b) 0.049152
Step-by-step explanation:
a) first strike comes on the third well drilled
=> two non-strikes and a strike
P = (0.8)^2 * (0.2)
= 0.128
b) third strike comes on the seventh well drilled
=> two strikes in first six wells and a strike in seventh
P = 6C2 * (0.2)^2 (0.8)^4 * (0.2)
= 0.049152
Which rectangular prism has a volume equal to the expression 6 * 3 * 4?
1 cubic un
= 1 cubic unit
- 1 cubicund
= 1 cubic unit
Answer:
The bottom right one
Step-by-step explanation:
i did the test
Fourth one or right one at the bottom rectangular prism has a volume equal to the expression 6 × 3 × 4 cubic unit.
What is volume?" Volume is total amount of space occupied by any three dimensional body."
Formula used
Volume of rectangular prism = Length × width ×height
According to the question,
Compare the expression of given volume with given diagrams
Given volume = 6 ×3×4
From the diagram we can conclude that right one at the bottom has length = 6 units, width = 3 units and height = 4 units.
Hence, Option(D) or right one at the bottom is the correct answer.

Estimate the square root of 5 to the nearest tenth
Answer:
Step-by-step explanation:
It's about +- 2.2. It equals 2.236067977 but can be rounded to 2.2. When you square root, the answer could be positive or negative.
The square root of 5 to the nearest tenth is 2.2.
We have to find out the square root of 5 that should be the nearest tenth.
So, the following procedure should be followed:
[tex]= \sqrt{5}\\\\= 2.2360679[/tex]
= 2.2
Therefore we can conclude that the square root of 5 to the nearest tenth is 2.2.

$2,500 is invested in an account earning 8.4% interest compounded annually. How many years did it take to reach $4,000?
Answer:
3 years
Step-by-step explanation:
Peggy and her mom have been living alone in an island ever since Peggy was born. To keep track of how old her daughter is, every day after Peggy was born, her mom carves a tick mark into a tree.
One day, Peggy's mom counted 2000 tick marks on the tree. How many years old is Peggy, rounded off to the nearest year? Remember that a year has 365 days.
Answer:
5 years
Step-by-step explanation:
Divide 365 by 2000. The answer is 5.4794. Rounded to the nearest whole it is 5.
Answer:
5 years
Step-by-step explanation:
What we know:
- 2000 days passed (since each tick mark represents a day)
- One year has 365 days
Let [tex]x[/tex] represent the number of years that passed.
If each year has 365 days, 365 multiplied by the number of years that passed should equal 2000.
[tex]365x=2000[/tex]
Divide both sides by 365 to isolate x
[tex]\frac{365x}{365} =\frac{2000}{365}[/tex]
[tex]x[/tex] ≈ [tex]5[/tex]
Therefore, Peggy is 5 years old.
