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.

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.

Step-by-step explanation:

Given that: {∛(125) + ∛(64) - ∛(1)}^(1/3)

= {∛(5 * 5 * 5) + ∛(4 * 4* 4) -∛(1)}^(1/3)

= {∛(5³) + ∛(4³) - ∛(1)}^(1/3)

[since, ⁿ√(a) = a^(1/n)]

= {(5³)^(1/3) + (4³)^(1/3) - (1)^(1/3)}^(1/3)

[since, (aᵐ)ⁿ = aᵐⁿ}

= {(5)^{3*(1/3)} + (4)^{3*(1/3)} - (1*1*1)}^(1/3)

= {{5)^1 + (4)^1 - 1}^(1/3)

= (5 + 4 -1)^(1/3)

= (9 - 1)^(1/3)

= 8^(1/3)

= (2*2*2)^(1/3)

= (2³)^(1/3)

[since, (aᵐ)ⁿ = aᵐⁿ]

= (2)^{3*(1/3)}

= (2)¹

= 2

Therefore, {∛(125) + ∛(64) - ∛(1)}^(1/3) = 2

Answer: Hence, the simplified form of , {∛(125) + ∛(64) - ∛(1)}^(1/3) is 2.

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°

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°

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.

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.

Spencer has a bag with 10 marbles. There are 6 white marbles and 4 black marbles.

Spencer picks a marble at random.

Write as a decimal the probability of Spencer picking a black marble

4 Black Marbles

+

6 white Marbles

=10

THE ANSWER IS :

4/10

Lowest Term :

2/5

As a Decimal:

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.

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
