Step-by-step explanation:
We're going to be factoring:
[tex]12 {x}^{4} + 27 {x}^{3} + 6 {x}^{2} [/tex]
We know that the GCF between 12, 27, and 6 is 3.
We also know that the GCF of x^4, x^3, and x^2 is x^2.
When factoring:
Use both of our GCFs, 3 and x^2 (3x^2).Divide our coefficients by the GCF.[tex]3{x}^{2} (4 {x}^{2} + 9x + 2)[/tex]
We know 3x^2 is the correct option since the polynomial is factored completely.
Answer:
[tex]3x^2[/tex]
Step-by-step explanation:
[tex]12x^4 + 27x^3 + 6x^2[/tex]
The coefficients of the variables are 12, 27 and 6. The greatest common factor (GCF) of these numbers is 3.
[tex]\implies 3(4x^4 +9x^3 + 2x^2)[/tex]
From inspection, the GCF of the variables is [tex]x^2[/tex]
[tex]\implies 3x^2(4x^2+9x + 2)[/tex]
Therefore, the GCF of the terms in the polynomial is [tex]3x^2[/tex]

1) Simplify the expression. –2x(1–3x) + (2x + 3)(3x – 2)
Make sure you show all your work for full credit. Use standard polynomial format.
Answer:
12x² + 3x - 6
Step-by-step explanation: -2x(1-3x) = -2x+6x²
(2x+3)(3x-2), first do 2x
2x × 3x = 6x²
then 2x × -2= -4x
we then move to the number 3
3 × 3x = 9x
3 × -2 = -6
after that we add them together
-2x + 6x² + 6x² - 4x +9x - 6 = 6x² + 6x² is 12x², -2x - 4x + 9x = 3x, and then -6 is by its self
= 12x² + 3x - 6
The simplified solution of the expression is 6x²- 4x - 6.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, and/or operators that can be evaluated to obtain a value. Expressions can be as simple as a single variable or number, or as complex as a combination of variables, numbers, and mathematical operations.
We can simplify the expression by distributing the terms and combining like terms:
E = -2x(1 - 3x) + (2x + 3)(3x - 2)
E = -2x + 6x² + (6x - 4x - 6)
E = 6x² - 4x - 6
Therefore, the simplified expression is 6x²- 4x - 6.

Answer:
a. 46.89 mph
b. 0.781 mi/min
c. 4126.22 ft/min
d. 68.77 ft/s
e. 1.28 min/mi
Step-by-step explanation:
a. Miles per hour
1. Convert 4 hours and 30 minutes into hours (4.5 hours).
2. Divide the distance traveled by the new time.
MPH = 211 mi / 4.5 hours = 46.89 mph
b. Miles per minute
1. Convert 4 hours and 30 minutes into minutes: (4*60+30) = 270 minutes
2. Divide the distance traveled by the new time
MPM = 211 mi / 270 min =0.781 mi/min
c. feet per minute
1. Use the converted time from part b (270 minutes)
2. Convert the distance traveled from miles to feet: (211*5280=1114080 ft)
3. Divide the converted distance by the converted time
ft/min = 1114080 ft / 270 minutes = 4126.22 ft/min
d. feet per second
1. Convert the time into seconds (270 minutes * 60 sec/min) = 16200 sec
2. Use the converted distance from part c (1114080 ft)
3. Divide the converted distance by the converted time
ft/s = 1114080 ft / 16200 sec = 68.77 ft/s
e. minutes per mile
1. use the converted time from part b (270 minutes)
2. divide the time by the distance traveled
minutes/mi = 270 min / 211 mi = 1.28 min/mi

Convert the angle - 3 radians to degrees, rounding to the nearest 10th.
Answer:
formula :
-3rad × 180/π = -171.9°
Step-by-step explanation:
hope that help's you :))!!
The measure of the angle in degrees is A = -171.9°
What is Central Angle?The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
r is the radius of the circle
Central Angle = 2 x Angle in other segment
Given data ,
Let the measure of the angle be A = -3°
Now , angle in degrees = angle in radians × 180°/π
Substituting the given value, we get:
The angle in degrees = (-3) × 180°/π
On simplifying the equation , we get
A = -171.8873385°
On rounding to the nearest tenth , we get
A = -171.9°
Hence , the angle is A = -171.9°

A linear mode is used to display the scores of a baseball team's games using the batting average of its top player. The correlation coefficient for the linear model is 0.37. Which statement about the linear model is true?
Using the correlation coefficient, it is found that we can say that there is a non-strong positive relationship between the scores of a baseball team's games and the batting average of its top player.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem, the coefficient is of 0.37, which is positive but less than 0.6, hence there is a non-strong positive relationship between the scores of a baseball team's games and the batting average of its top player.

THE ANSWER IS :

Lowest Term :

As a Decimal:
0.4MABUHAY!The probability of Spencer picking a black marble is approximately 0.4 or 40%.
To find the probability of Spencer picking a black marble, we can use the formula for probability:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
In this case, the number of favorable outcomes (picking a black marble) is 4, as there are 4 black marbles in the bag. The total number of possible outcomes (picking any marble) is 10, as there are 10 marbles in total.
Now, we can calculate the probability:
Probability = 4 / 10
Simplifying the fraction, we get:
Probability = 2 / 5
To express the probability as a decimal, divide the numerator (2) by the denominator (5):
Probability = 2 ÷ 5
Probability ≈ 0.4
The probability represents the likelihood of an event occurring, and in this case, it tells us the chance of Spencer picking a black marble out of the 10 marbles in the bag.
