Answer:

3x+6=72

Step-by-step explanation:

1.st integer is x

2.nd is  x+2

Thrd is x+4

So the sum is x+x+2+x+4=3x+6=72

The given equation y = 3x + 45 in form ax+by=c is 3x - y = - 45.

So,  y=3x+45 into ax+by=c form:

Therefore, the given equation in form ax+by=c is 3x - y = - 45.

Given:

Results of a spinner shown in the table.

To find:

The experimental probability of the spinner landing on a 1 or 7.

Solution:

From the given table it is clear that,

Spinner landing on 1 = 12 times

Spinner landing on 7 = 9 times

Spinner landing on 1 or 7 = 12+9 = 21 times

Total number of times spinner landed = 12+35+72+29+40+18+9+65+42 = 322 times

Now, the experimental probability of the spinner landing on a 1 or 7 is

\(P=\dfrac{\text{Spinner landing on 1 or 7}}{\text{Total number of times spinner landed}}\)

\(P=\dfrac{21}{322}\)

\(P=0.06521739\)

\(P\approx 0.065\)

Therefore, the correct option is A.

A population is a complete set of individuals or objects that share common characteristics. It is an entire group of people, animals, plants, or objects that can be studied. A population can also be a group of people living in a certain geographical area.

A sample is a subset of a population. It is a smaller group of individuals or objects drawn from the population that are used to make inferences about the population as a whole.

A sample is used in statistical analysis to estimate population characteristics, such as mean, median, and variance. The accuracy of the estimates depends on the size and representativeness of the sample.

The value of the variable 'w' for the given equation 7 ( w + 7 )³ = 7(6³)  is equal to w = -1.

As given in the question,

Given equation is equal to :

7 ( w + 7 )³ = 7(6³)

Divide both the side of the equation by 7 we get,

⇒ 7 ( w + 7 )³ / 7 = 7(6³) /7

⇒( w + 7 )³ = (6³)  

Take cube root both the side of the equation we get,

⇒∛( w + 7 )³ = ∛(6³)  

⇒ w + 7 = 6

Now subtract 7 from both the side of the equation we get,

⇒w + 7 - 7 = 6 - 7

⇒ w = -1

Therefore, the value of the variable 'w' for the given equation is equal to w = -1.

Answer:

Given the information you provided, we can model cellular phone usage over time with an exponential growth model. An exponential growth model follows the equation:

`y = a * b^(x - h) + k`

where:

- `y` is the quantity you're interested in (cell phone usage),

- `a` is the initial quantity (34 million in 1995),

- `b` is the growth factor (1.22, representing 22% growth per year),

- `x` is the time (the year),

- `h` is the time at which the initial quantity `a` is given (1995), and

- `k` is the vertical shift of the graph (0 in this case, as we're assuming growth starts from the initial quantity).

So, our specific model becomes:

`y = 34 * 1.22^(x - 1995)`

To find the cellular usage in 2003, we plug 2003 in for x:

`y = 34 * 1.22^(2003 - 1995)`

Calculating this out will give us the cellular usage in 2003.

Let's calculate this:

`y = 34 * 1.22^(2003 - 1995)`

So,

`y = 34 * 1.22^8`

Calculating the above expression gives us:

`y ≈ 97.97` million.

So, the cellular phone usage in 2003, according to this model, is approximately 98 million.

Answer: 2j+22

Step-by-step explanation:

Twice Jose's height = 2j

22 more = +22

22 more than twice Jose's height = 2j+22

Increasing 2400 by 5% gives us 2520

we can increase the value by using the formula:

\(initial value+ percentage increase *initial value\) = increased percentage

in the aforementioned question we have

initial value = 2400

percentage increase = 5%

thus we can find out the increased percentage by:

2400 + 2400 X (5/100)

=2400 + 120

=2520

the value by which 2400 is increased is 120

to arrive at the increased value which is 2520

If the total height between two floors is 9'0 1/2" and 14 risers are to be used in a set of stairs, the height of each riser would be approximately 7.75 inches.

To find the height of each riser in a set of stairs given the total height between two floors, we need to divide the total height by the number of risers.

First, let's convert the total height to a consistent unit. The distance between two floors is given as 9'0 1/2". We can convert this to inches by multiplying the feet by 12 and adding the remaining inches:

9 feet = 9 * 12 = 108 inches

0 1/2 inch = 0.5 inch

Total height = 108 + 0.5 = 108.5 inches

Next, we divide the total height by the number of risers (14) to find the height of each riser:

Height of each riser = Total height / Number of risers

Height of each riser = 108.5 inches / 14

Using a calculator, we can compute:

Height of each riser ≈ 7.75 inches

Therefore, the height of each riser in the set of stairs would be approximately 7.75 inches.

Step-by-step explanation:

Let be \(y = k\cdot x +1\) the expression of the line, where \(x\) and \(y\) are the independent and dependent variables, respectively. If we know that \(x = 2\) and \(y = -7\), the value of \(k\) is:

\(-7 = 2\cdot k +1\)

\(2\cdot k = -8\)

\(k = -4\)

The equation of the line is \(y = -4\cdot x +1\), which is graphed below.
