Thus we find that;

Answers
Answer:
2 hours.
Step-by-step explanation:
2 and a half hours is 2.5 hours.
30 minutes is 0.5 hours.
2.5 - 0.5 = 2 hours.
Answer:
2 hours (I know I'm late but I like to answer things TvT)
Step-by-step explanation:
2 hours can be converted into 120 minutes (60 mins in an hour, 60 x 2 = 120)
120 minutes plus the half hour (30 mins) equals 150 minutes.
150 minutes minus 30 minutes equals 120 minutes, so 2 hours is your answer.

which is closest to the probability that chris's guess ends up being exactly 4 less than the result?
Answers
The probability that Chris's guess ends up being exactly 4 less than the result is approximately 0.5. So, the correct option is c).
The possible values of X are 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. The expected value of X can be calculated as
E(X) = (1/6) x 2 + (1/6) x 3 + (1/6) x 4 + (1/6) x 5 + (1/6) x 6 + (1/6) x 7 + (1/6) x 8 + (1/6) x 9 + (1/6) x 10 + (1/6) x 11 + (1/6) x 12
E(X) = 7
To be 4 less than the result, Chris's guess must be X - 4. Therefore, Chris's guess can be 2, 3, 4, 5, 6, 7, 8, 9, or 10.
The probability that Chris's guess ends up being exactly 4 less than the result can be calculated by finding the sum of the probabilities of getting X = 6, 7, or 8, since these are the only values of X that satisfy the condition that X - 4 is one of Chris's possible guesses
P(X = 6) = 5/36
P(X = 7) = 6/36
P(X = 8) = 5/36
P(Chris's guess is X - 4) = P(X = 6) + P(X = 7) + P(X = 8)
P(Chris's guess is X - 4) = 16/36
P(Chris's guess is X - 4) ≈ 0.44
Therefore, the closest answer choice is 0.5. So, the correct answer is c).

4. Consider the map D: P2 P2 defined by D(ao + a₁x + a₂x²) = a₁ + 2a2x and the basis B = {x+1, x2, 2x²} of P₂. Determine [D]B, the matrix representation of the function over the basis B.
Answers
The matrix representation of the function over the basis B is [1 0 0, 0 2 0, 2 0 4].
In order to find the matrix representation of the function over the basis B, we need to express the images of each basis vector as a linear combination of the basis vectors and record the coefficients as column vectors in a matrix. The given map is D(ao + a₁x + a₂x²) = a₁ + 2a2x. Consider the basis B = {x+1, x², 2x²}.Now, we have to determine [D]B. We know that[D]B = ([D]B)1[D]B([D]B)2where [D]B is the matrix representation of D over B, ([D]B)1 is the first column vector of [D]B, and ([D]B)2 is the second column vector of [D]B.
Let us find out the images of the basis vectors under D.D(x + 1) = 1 + 0(x) + 2(x) = 1 + 2xD(x²) = 0 + 2(x²) + 0(x) = 2x²D(2x²) = 0 + 0(x²) + 4(x) = 4xThe images of the basis vectors under D are given as follows: D(x + 1) = 1 + 2x= (1)(x+1) + 0(x²) + 2(2x²)D(x²) = 2x²= 0(x+1) + 2(x²) + 0(2x²)D(2x²) = 4x= 0(x+1) + 0(x²) + 4(2x²)Thus, we can express the images of the basis vectors under D as linear combinations of the basis vectors as follows: D(x + 1) = 1(x+1) + 0(x²) + 2(2x²)D(x²) = 0(x+1) + 2(x²) + 0(2x²)D(2x²) = 0(x+1) + 0(x²) + 4(2x²)Therefore, we can obtain [D]B as follows:[D]B = [1 0 0, 0 2 0, 2 0 4].

Answer:
The two equal parts are 30 cm, the third part is 54 cm
Step-by-step explanation:
x = third part
(5/9)x + (5/9)x + x = 114

determine the percentage rate of change of f(t) = e-0.09t2 at t = 1 and t = 5.
Answers
To find the percentage rate of change of a function at a specific point, we need to find the derivative of the function. The percentage rate of change of f(t) = e^-0.09t^2 at t=1 and t=5 is approximately -17.75% and -13.65%, respectively.
To find the percentage rate of change of a function at a specific point, we need to find the derivative of the function at that point and then multiply it by 100%. Thus, the derivative of f(t) is given by:
f(t)=e^-0.09t^2
f'(t) = (-0.18t)e^(-0.09t^2)
Evaluating f'(1) and f'(5) yields:
f'(1) = (-0.18)(1)e^(-0.09(1)^2) ≈ -0.1606
f'(5) = (-0.18)(5)e^(-0.09(5)^2) ≈ -0.1851
To find the percentage rate of change, we multiply the derivative by 100% and divide by the function value at the respective point:
Percentage rate of change at t=1:
= (f'(1)/f(1)) * 100%
= (-0.1606/e^-0.09) * 100%
≈ -17.75%
Percentage rate of change at t=5:
= (f'(5)/f(5)) * 100%
= (-0.1851/e^-0.09) * 100%
≈ -13.65%
Therefore, the percentage rate of change of f(t) at t=1 and t=5 is approximately -17.75% and -13.65%, respectively.

For a recent paint job, Josh mixed red and white paint to make two different shades of pink. When the job was done, Josh ended up with leftover paint: 5 gallons of dark pink paint (80% red) and 4 gallons of light pink paint (30% red). Josh wants to make a medium pink color (50% red) to paint his daughter's bedroom. He will need 3 gallons to completely cover the walls. How much of each of the leftover paints should Josh mix to achieve his desired color?
? gallons of dark pink paint
? gallons of light pink paint
Answers
Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.
To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.
Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.
The total amount of paint needed is 3 gallons, so we have the equation:
x + y = 3
The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:
(80/100)x + (30/100)y = (50/100)(x + y)
Simplifying this equation, we get:
0.8x + 0.3y = 0.5(x + y)
Now, we can solve this system of equations to find the values of x and y.
Let's multiply both sides of the first equation by 0.3 to eliminate decimals:
0.3x + 0.3y = 0.3(3)
0.3x + 0.3y = 0.9
Now we can subtract the second equation from this equation:
(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)
-0.5x = 0.9 - 0.5x - 0.5y
Simplifying further, we have:
-0.5x = 0.9 - 0.5x - 0.5y
Now, rearrange the equation to isolate y:
0.5x - 0.5y = 0.9 - 0.5x
Next, divide through by -0.5:
x - y = -1.8 + x
Canceling out the x terms, we get:
-y = -1.8
Finally, solve for y:
y = 1.8
Substitute this value of y back into the first equation to solve for x:
x + 1.8 = 3
x = 3 - 1.8
x = 1.2
Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

Given that Aaron has 47m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank. The fourth side of the enclosure would be the river.
The area of the land is 266 square meters.To find the possible dimensions (length and width) of the field, we can use the given information.The length of fencing required = 47 m.
Since the fence needs to be built on three sides of the rectangular plot, the total length of the sides would be 2l + w = 47.1. When l = 10 and w = 13, we have:
Length of the field, l = 10 m Width of the field, w = 13 mArea of the field = l × w = 10 × 13 = 130 sq. m2. When l = 11 and w = 12,
we have:Length of the field, l = 11 m
