Step-by-step explanation:

3 ( x + 1 )

= 3 ( x ) + 3 ( 1 )

= 3x + 3

3x + 3 = 3x + 3

Any number can substituted for x.

Answer: Yes

Step-by-step explanation: First, distribute 3(x+1), which is 3x+3. Then we have 3x+3=3x+3, which is the same thing.

Answer:

a. 10x - 2

Step-by-step explanation:

4x - 2 +6x ( collect like terms )

4x +6x - 2

10x - 2

4 = -2(x-2) + 4

or, 4 = -2x + 4 + 4

or, 4 = -2x + 8

or, 4 - 8 = -2x

or, -4 = -2x

or, -4/-2 = x

or, 2 = x

The value of x is 2.

Answer:

x = 1

Step-by-step explanation:

4 = -2( x - 2) + 4

4 = -2x - (-2) +4

4 = -2x + 2 + 4

4 = -2x + 6

4 - 6 = -2

6 - 6 = 0

-2 = -2x

x = 1

bcz he can't put a 0.725 fish so it will be rounded up back to 12

The greatest number of neon tetra fish he puts in the tank is 12.

A cuboid is a solid in three dimensions with six rectangular faces, eight vertices, and twelve edges. Three dimensions, including length, breadth, and height, define a cuboid. A cuboid with integer edges is referred described as being perfect.

Given:

Sahil has a fish tank in the shape of a cuboid, as shown in the diagram.

The tank is 55 cm wide, 28 cm long and height is 33 cm.

And the surface of the water in the tank is 3 cm below the top of the tank.

That means,

to determine the volume,

So, the volume of cuboid

= 55 x 28 x 33

= 50820 cubic centimeters.

And we know 1000 cubic centimeters is 1 liter of water.

So, 50820 = 50.820

And divide by 4

We get the greatest number of neon tetra fish he puts in the tank.

50.820 / 4

= 12.705

≈ 12

Therefore, 12 is the required number for neon tetra fish.

Answer:

2nd one is 4

Step-by-step explanation:

The figure given in the problem represents 1/4 of the full circle. So, the answer is 1/4.

Here's how we can arrive at that conclusion: We know that a circle has 360 degrees, and the angle given in the figure is a central angle that spans across one of the quarters of the circle.

Since we have four equal parts in a full circle, each quarter must have an angle measure of 360 degrees / 4 = 90 degrees. Therefore, the central angle in the figure represents an angle measure of 90 degrees, which is equivalent to one-quarter of the full circle. Hence, the answer is 1/4.

The distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Given that:

AB = 370 miles

angle A = 24 degrees

BC = 240 miles

angle B = 37 degrees 

To determine the distance from point A to C, we can use the cosine law since we are given two angles and two sides of a regular triangle. 

The angle opposite side AC is angle B which is equal to 37 degrees. 

(AC)^2 =(AB)^2 + (BC)^2 - 2(AB)(BC)cos(B)

Now we have to solve for AC:

(AC)^2 =(370)^2 + (240)^2 - 2(370)(240)cos(37) 

AC = 229.48 miles.

Hence the answer is, the distance from point A to point C and the bearing from point A to point C is 229.5 miles.

Answer: 9

Step-by-step explanation:

The histogram doesn't support Alfonso's claim and the correct option is 5: No, the distribution is skewed to the left with a mean age greater than 36.

What is a histogram?

A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.

Consider the given histogram at the photo below. It is an left-skew histogram, since it has a long tail to the left side.

We need to estimate the mean of the given data. To do so, we need to multiply each class midpoint with its probability, and sum them.

For example, for the first one, the midpoint is 32 and the probability is 0.03 (read the value on the y-axis). For, the second one, the midpoint is 33 and the probability is 0.04, for the third the midpoint is 34 and the probability is 0.05, and so on. All needed values are presented below.

1. midpoint = 32, probability= 0.03

2. midpoint = 33, probability = 0.04

3. midpoint = 34, probability = 0.05

4. midpoint = 35, probability = 0.1

5. midpoint = 36, probability =0.11

6. midpoint = 37, probability = 0.13

7. midpoint = 38, probability = 0.2

8. midpoint = 39, probability = 0.09

So, it is obtained that -

μ = 0.03 · 32 + 0.04 · 33 + 0.05 · 34 + 0.10 · 35 + 0.11 · 36 + 0.13 · 37 + 0.25 · 38 + 0.20 · 39 + 0.09 · 40

μ = 37.15

Therefore, this histogram is left-skewed with mean greater than 36.

Parameters are the values that are computed from a complete census, which are considered to be precise and valid measures of the population. So, option(b) is right one.

In statistics, a population parameter is a number that identifies an entire group of people or population. This should not be confused with arguments in other forms of mathematics that refer to values that remain constant for a mathematical function. Note that the population parameter is not a statistic, it refers to data for a sample or group of the population. With good research, we can get statistics that accurately estimate the population. Statistics is a numerical measure described with sample data. Therefore, the parameter is a numerical description of the characteristic of population.

The probability of randomly selecting the chair and the ranking member is 1/105 or approximately 0.0095.

There are 15 members of the Senate Committee on Homeland Security and Governmental Affairs, two of whom are selected to serve as the committee chair and ranking member. Each member is equally likely to be chosen for either of these positions.

To begin, we must first determine the total number of ways two members can be selected from a committee of 15. This is calculated using the combination formula:

nCr = (n!)/((r!)(n-r)!)where n = 15 and r = 2.

Thus,

nC2 = (15!)/((2!)(15-2)!)

nC2 = (15x14)/(2x1)nC2

= 105

Now we must determine the probability of selecting one member to be the committee chair and the other to be the ranking member.

This is calculated as follows: P = 1/105 or approximately 0.0095. Hence, the probability of randomly selecting the chair and ranking member is 1/105 or approximately 0.0095.

The area of square x will be one-fourth of the area of square y. Then the correct option is C.

It is a polygon with four sides. The total interior angle is 360 degrees. A square's opposite sides are parallel and all sides are equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

There are two squares.

The perimeter of square x is half the perimeter of square y.

Let the side of the square x be a and the side length of the square y be b. Then we have

Perimeter x = Perimeter y / 2

              4a = 2b

              2a = b

Then the area of the square x will be

Area of square x = (2a)²

Area of square x = 4a²

Step-by-step explanation:

The product (√5/-5) * (√5/-2) simplifies to 1/2.

To simplify the product of the radical expressions √5/-5 and √5/-2, we can apply the rule of multiplying radicals.

√5/-5 can be written as (√5)/(-5) and √5/-2 can be written as (√5)/(-2).

When multiplying these two expressions, we multiply the numerators together and the denominators together:

(√5)/(-5) * (√5)/(-2) = (√5 * √5) / (-5 * -2)

The product of (√5 * √5) simplifies to 5 because the square root of 5 multiplied by itself gives us 5.

The product of (-5 * -2) simplifies to 10 because the product of two negative numbers is positive.

So, the simplified product of the given radical expressions is:

5 / 10 = 1/2

Therefore, the product (√5/-5) * (√5/-2) simplifies to 1/2.
