Answer:

A. Two column proof

Step-by-step explanation:

It is an illustration of theoretical probability.

Theoretical probability establishes the probability of certain events occurring.

The ratio of the entire number of conceivable possibilities to the intended outcome is known as theoretical probability.

In this case, the intended consequence is earning a 2, which is only one of the six potential possibilities. The possibility of receiving a 2 is.

Observance determines empirical probability. Nothing about the observing of the specified episode is indicated in the question, hence it is not an empirical probability.

Step-by-step explanation:

Step-by-step explanation:

8x^2-6x!15. that's the answer

The equation of the tangent line to the graph of f(x) = 4x^3 + 5 at the point (1, 3) is y = 12x - 9.

To find the equation of the tangent line to the graph of the function f(x) = 4x^3 + 5 at the point (1, 3), we need to determine the slope of the tangent line at that point and then use the point-slope form of a line.

First, we find the derivative of f(x) with respect to x:

f'(x) = 12x^2

Next, we evaluate the derivative at x = 1 to find the slope of the tangent line:

f'(1) = 12(1)^2 = 12

The slope of the tangent line is 12. Using the point-slope form, we have:

y - 3 = 12(x - 1)

Simplifying, we get:

y - 3 = 12x - 12

Finally, rearranging the equation, we obtain the equation of the tangent line:

y = 12x - 9

The probability that chad gets at least 2 heads on 3 flips is 1/2 which was found using the sample space.

Given: To decide who will pay for lunch, Jeff and Chad decide to flip a coin three times. Chad chooses heads, and in order to win and have Jeff pay for his lunch, he must get heads at least twice out of three times.

Let,

H = Heads

T = Tails

Sample space =  {HHH, HTH,THH,TTH, HHT, HTT,THT,TTT​}

Total number of possible outcomes = 8

Probability that chad gets at least 2 heads is given as:

P(A)=P(getting two heads)+P(getting 3 heads)

= 3/8 + 1/8

= 4/8

= 1/2

Therefore,  the probability chad gets at least 2 heads on 3 flips is 1/2 which was found using the sample space.

Answer: 2289.06

Step-by-step explanation:

math expert

Answer:

r = 169.56 in. / 2π ≈ 27 in.

Now we can use the radius to find the area:

Area = πr^2 ≈ π(27 in.)^2 ≈ 2289.06 in^2

So the area of the circular table is approximately 2289.06 square inches, rounded to the nearest hundredth. The answer is option C.

\(8 \times 103 < 9 \times 100\)

This is because :-

\( = 8 \times 103\)

\( = 824\)

a. The null hypothesis (H0) is that the proportion of those who are adequately prepared financially for retirement is the same for people in the 66-69 age group who did not complete high school as it is for the population of the 66-69-year-old (71%).

The alternative hypothesis (Ha) is that the proportion of those who are adequately prepared financially for retirement is smaller for people in the 66-69 age group who did not complete high school than it is for the population of the 66-69-year-old.

b. To calculate the p-value for this hypothesis test, we can use a one-sample proportion test. The sample proportion (p-hat) is 165/300 = 0.55. Using a z-test, with a z-score of -2.35 and a standard deviation of 0.058, the p-value is 0.011.

c. At a significance level of 0.01, the p-value of 0.011 is less than the significance level, so we reject the null hypothesis. We can conclude that there is evidence that the proportion of those who are adequately prepared financially for retirement is smaller for people in the 66-69 age group who did not complete high school than it is for the population of the 66-69-year-old.

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año

El valor de depreciación de la camioneta es de $4200 por año.

Dado que Juana compró una camioneta 4x4 a $42 000; y además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal durante 6 años, para determinar, si al quinto año la camioneta tendrá un valor de $21 000, cuál es el valor de la depreciación de la camioneta, se debe realizar el siguiente cálculo:

Por lo tanto, el valor de depreciación de la camioneta es de $4200 por año.

If f(x, y, z) = xyzi + yj + zk, the divergence of the curl of the vector field f is zero.

To find the divergence of the curl of the vector field f(x,y,z) = xyzi + yj + zk, we first need to compute the curl of f, which is given by:

curl f = (∇ × f) = ∂(zk)/∂y - ∂(yj)/∂z + (∂(yj)/∂x - ∂(xyzi)/∂y)k + (∂(xyzi)/∂z - ∂(zk)/∂x)j + (∂(zk)/∂x - ∂(yj)/∂y) i

Simplifying this expression, we get:

curl f = (-z)i + xj + yk

Next, we need to find the divergence of the curl of f, which is given by:

div(curl f) = ∇ · (∇ × f) = ∂(∂(zk)/∂y - ∂(yj)/∂z)/∂x + ∂(∂(yj)/∂x - ∂(xyzi)/∂y)/∂y + ∂(∂(xyzi)/∂z - ∂(zk)/∂x)/∂z

Substituting the values from the curl f expression, we get:

div(curl f) = ∂(-z)/∂x + ∂(x)/∂y + ∂(y)/∂z

Simplifying this expression, we get:

div(curl f) = 0

BD bisects angle ABC for the value of x = 4

An angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.

An angle is a shape created by two rays or lines that meet at the same terminal. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an item or a form into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

Since 3x + 1 and 4x - 3 are angle bisectors so,

3x + 1 = 4x - 3

The solution to each of the arithmetic sequence are:

1) a₁₀ = 56

2) a₁₀ = 87

3) missing term is 13

4) missing term is 14

The formula for the nth term of an arithmetic sequence is:

aₙ = a + (n - 1)d

where:

a is first term

n is nth term

d is common difference

1) a = 2

d = 6

a₁₀ = 2 + (10 - 1)6

a₁₀ = 2 + 54

a₁₀ = 56

2) a = 15

d = 8

a₁₀ = 15 + (10 - 1)8

a₁₀ = 87

3) The missing term will be gotten by finding the common difference.

d = (22 - 4)/2

d = 18/2

d = 9

missing term = 4 + 9 = 13

4) The missing term will be gotten by finding the common difference.

d = (53 - 25)/2

d = 28/2

For the bottom left corner:

\(10^{2} + 6^{2} \\= 100 + 36\\= 136\)

Now, 10 - 6 = 4

136 / 4 = 34

For the top left corner:

\(7^{2} + 5^{2} \\= 49 + 25\\= 74\)

Now, 7 - 5 = 2

74 / 2 = 37

For the top right corner:

\(8^{2} + 4^{2} \\= 64 + 16\\= 80\)

Now, 8 - 4 = 4

80 / 4 = 20

For the bottom right corner:

\(6^{2} + 4^{2} \\= 36 + 16\\= 52\)

Now, 6 - 4 = 2

52 / 2 = 26

Another method:

7×6-5=37

6×4+10=34

10×4-6=34

4×3+8=20

8×3-4=20

So, 4×5+6=26

6×5-4=26

Firstly we have to multiply number with smaller number from the both number, then, multiply that constant number with larger number and then subtract smaller number you will get same number, in this with 4 only 5 constant number following this rule 4×5+6=26, 6×5-4=26, if you multiply 4 with 6, then, 4×6+6=30, 6×6-4=32, and with 7, 4×7+6=34, 6×7-4=38.

The mean, variance, and standard deviation of the distribution is 20.74, 1.3210, and 1.1493, respectively.

First, the mean can be found using the following formula:

Mean = ∑x(p(x))

Mean = (19)(0.22) + (20)(0.20) + (21)(0.32) + (22)(0.14) + (23)(0.12)

Mean = 4.18 + 4 + 6.72 + 3.08 + 2.76

Mean = 20.74


Next, the variance can be found using the following formula:

Variance = ∑(x-mean)²(p(x))

Variance = (19-20.74)²(0.22) + (20-20.74)²(0.20) + (21-20.74)²(0.32) + (22-20.74)²(0.14) + (23-20.74)²(0.12)

Variance = 0.5362 + 0.0552 + 0.0173 + 0.1754 + 0.5369

Variance = 1.3210


Finally, the standard deviation can be found using the following formulas:

Standard deviation = √variance

Standard deviation = √1.3210

Standard deviation = 1.1493


So, the mean is 20.74, the variance is 1.3210, and the standard deviation is 1.1493, all rounded to 4 decimal places.
