According to the given question, the sequence can be split in two separate sequences by taking alternate terms -

1) 4, -16, 64, B

2) 8, -32, A

Now clearly the logic is:

Next term is obtained by multiplying the previous term with -4.

Let's check 4x(-4) = -16x(-4) = 64

∴ B = 64x(-4) = -256

Similarly, 8x(-4) = -32

∴ A = -32x(-4) = 128

Hence completed sequence is 4, 8, -16, -32, 64, 128, -256.

Answer: 340

Step-by-step explanation:

Answer:

  340 in²

Step-by-step explanation:

The total surface area of the composite figure can be considered to be the sum of the surface area of the rectangular prism base and the lateral surface area of the cylinder. Effectively, the hidden area at the interface between the two shapes is translated to the top of the cylinder, where it is visible again.

__

The area of a rectangular prism is given by the formula ...

  A = 2(LW +H(L +W))

Using the given dimensions, we find the area of the rectangular prism base to be ...

  A = 2((9 in)(9 in) +(3 in)(9 in +9 in)) = 2(81 +3(18)) in² = 270 in²

Since the bottom area will not be painted, we can subtract its area of 81 in².

  prism area = 270 in² -81 in² = 189 in²

__

The lateral area of the cylinder is the product of its circumference and height.

  A = 2πrh

  A = 2(3.14)(4 in)(6 in) = 150.72 in² . . . . lateral area

__

The painted area is the sum of the areas just computed:

  painted area = prism area + cylinder area

  = 189 in² +150.72 in² = 339.72 in² ≈ 340 in²

To the nearest square inch, the amount of paint needed is that required to cover an area of 340 in².

There is no number in which the value of the 2 is ten times the value of the 2 in 37.632.

To find the number in which the value of 2 is ten times the value of the 2 in 37.632, we need to examine the place value of the 2 and compare it to other numbers in the given decimal number.

In the number 37.632, the place value of the first 2 is in the tenths position, and the place value of the second 2 is in the hundredths position.

To determine the number in which the value of the second 2 is ten times the value of the first 2, we need to look at the digits that come after the second 2, specifically the thousandths and beyond.

In this case, the digit immediately following the second 2 is 6. To determine if it is ten times the value of 2, we compare it to 2 multiplied by 10.

2 * 10 = 20

Since 6 is not equal to 20, we can conclude that the value of 2 in 37.632 is not ten times the value of the second 2.

Therefore, there is no number in which the value of the 2 is ten times the value of the 2 in 37.632.

Answer:

speed of boat is 35 mph

speed of river is 5mph.

Step-by-step explanation:

Let the speed of boat be u mph

let the speed of river be v mph

When boat travel downstream

in that case flow  of river will support the speed of boat hence

speed of river will be added to speed of boat

Thus,

speed of boat in downstream = speed of boat + speed of river = u + v

Given

the boat travels at 40 mph downstream

thus,

u + v = 40           -----1

When boat travel upstream

in that case flow  of river will oppose the speed of boat hence

speed of river will be subtracted from  speed of boat

Thus,

speed of boat in downstream = speed of boat -speed of river = u - v

Given

the boat travels at 30 mph upstream

thus,

u - v = 30  ----2

adding 1 + 2

we have

u + v = 40  

+ u - v = 30

2u = 70

u = 70/2 = 35

Thus,

speed of boat is 35 mph

using u = 35 in u + v = 40  

we have

35 + v = 40

v = 40 - 35 = 5

Thus, speed of river is 5mph.

To find the value of b (in terms of c and d) for which the integral from c to d of (x + b)dx is equal to zero, we can solve the integral equation.

The integral of (x + b) with respect to x is given by (1/2)x^2 + bx, and we need to evaluate it from c to d. So the integral equation becomes:

(1/2)d^2 + bd - (1/2)c^2 - bc = 0

To solve for b, we can simplify the equation and rearrange it. First, we combine like terms:

(1/2)(d^2 - c^2) + b(d - c) = 0

Next, we can factor out (d - c) from the equation:

(1/2)(d - c)(d + c) + b(d - c) = 0

Now we can divide both sides of the equation by (d - c):

(1/2)(d + c) + b = 0

Finally, solving for b, we have:

b = -(1/2)(d + c)

Therefore, the value of b in terms of c and d that makes the integral equal to zero is -(1/2)(d + c).

3x + 2y = 35

Solving

3x + 2y = 35

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3x + 2y + -2y = 35 + -2y

Combine like terms: 2y + -2y = 0

3x + 0 = 35 + -2y

3x = 35 + -2y

Divide each side by '3'.

x = 11.66666667 + -0.6666666667y

Simplifying

x = 11.66666667 + -0.6666666667y

Given:

The three lengths in the options.

To find:

Which three lengths could be the lengths of the sides of a triangle?

Solution:

If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.

In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.

Sum of two smaller sides is:

\(4+8=12\)

\(4+8<13\)

So, the triangle is not possible.

In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.

Sum of two smaller sides is:

\(13+11=24\)

\(13+11>23\)

So, the triangle is possible.

In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.

Sum of two smaller sides is:

\(5+12=17\)

\(5+12<18\)

So, the triangle is not possible.

In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.

Sum of two smaller sides is:

\(8+16=24\)

\(8+16<25\)

So, the triangle is not possible.

Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

Answer:

60 degrees

Step-by-step explanation:

First of all, we have to set up an equation to solve this. The angles of a triangle add up to 180 degrees. We need to find the internal angle of C, which would be 180-(10x-45).

For our equation, we can set 3x+4x+[180-(10x-45)] equal to 180.

Add like terms:

7x+[180-(10x-45)] = 180

Distribute:

7x+180-10x+45 = 180

Add like terms once again:

-3x+225 = 180

Subtract 225 on both sides:

-3x = -45

Divide by -3 on both sides:

x = 15

Plug in 15 for x in the value 4x:

<B = 60 degrees

A. The number of people on a jury is a quantitative variable because it consists of a count.

In the context of data analysis, variables can be classified as either qualitative or quantitative. Qualitative variables are categorical in nature and represent qualities or attributes that cannot be measured or expressed numerically. On the other hand, quantitative variables represent quantities or measurements that can be expressed in numerical form.

The number of people on a jury is a quantitative variable because it can be measured and expressed as a count. Each jury has a specific number of members, such as 12 individuals for a standard jury. This count allows for quantitative analysis and statistical operations to be performed on the variable. Therefore, the number of people on a jury falls under the category of a quantitative variable.

Light bulbs is normally distributed with a variance of 625 and a mean lifetime of 520 hours, we need to calculate the cumulative probability up to 549 hours. The answer will be rounded to four decimal places.

Given a normally distributed lifetime with a mean of 520 hours and a variance of 625, we can determine the standard deviation (σ) by taking the square root of the variance, which gives us σ = √625 = 25.

To find the probability of a bulb lasting for at most 549 hours, we need to calculate the area under the normal distribution curve up to 549 hours. This can be done by evaluating the cumulative distribution function (CDF) of the normal distribution at the value 549, using the mean (520) and standard deviation (25).

The CDF will give us the probability that a bulb lasts up to a certain point. Rounding the result to four decimal places will provide the desired precision.

The problem involves using normal distribution to find the probability of a given outcome. Using the Z-score, we can determine that the probability of a light bulb lasting for at most 549 hours is approximately 0.8770 or 87.70%

Given the mean (µ) of the lifetime of a bulb is 520 hours. Also, the variance (σ²) is given as 625. Thus, the standard deviation (σ) is the square root of the variance, which is 25.

To find the probability of a bulb lasting for at most 549 hours, we first calculate the Z score. The Z-score formula is given as follows: Z = (X - µ) / σ, where X is the number of hours, which is 549. So substitute the given values into the formula. Z = (549 - 520) / 25, the Z value is 1.16.

We then look up the Z-table to find the probability associated with this Z-score (1.16), which is approximately 0.8770. Therefore, the probability of a bulb lasting for at most 549 hours is approximately 0.8770 or 87.70%.

Simple Math.

The maple syrup level is increasing at a rate of approximately 0.0143 feet per minute when the syrup is 5 feet deep.

To find the rate at which the maple syrup level is increasing when the syrup is 5 feet deep, we can use the concept of related rates and the formula for the volume of a cone.

The volume of a cone is given by the formula V = (1/3) * π * r^2 * h, where r is the radius of the cone's base and h is the height.

In this case, the radius of the cone is 20 feet, and the height is changing with time. Let's denote the changing height as dh/dt (the rate at which the height is changing over time).

We are given that the syrup is being pumped into the vat at a rate of 6 cubic feet per minute, which means the volume is changing at a rate of dV/dt = 6 cubic feet per minute.

We want to find dh/dt when the syrup is 5 feet deep. At this point, the height of the cone is h = 5 feet.

Using the formula for the volume of a cone, we have V = (1/3) * π * r^2 * h. Taking the derivative of both sides with respect to time, we get:

dV/dt = (1/3) * π * r^2 * (dh/dt).

Substituting the given values and solving for dh/dt, we have:

6 = (1/3) * π * (20^2) * (dh/dt).

Simplifying the equation, we find:

dh/dt = 6 / [(1/3) * π * (20^2)].

Evaluating this expression, we can find the rate at which the maple syrup level is increasing when the syrup is 5 feet deep.

dh/dt = 6 / [(1/3) * 3.14 * 400] ≈ 6 / (0.3333 * 1256) ≈ 6 / 418.9 ≈ 0.0143 feet per minute.

Because X and Y are independent variables and identically distributed, we can conclude that P(X-Y>0) = P(X>Y) which comes out with a value of 1 /2.

The difference between two normally distributed random variables is also normally distributed with a mean equal to the difference of the means and a variance equal to the sum of the variances.

Therefore, X-Y is normally distributed with a mean of:
