Answer:

m = 3/4

Step-by-step explanation:

We have the points (-2,2) and (2,5). We can use those to calculate the slope:

m = 5 - 2 / 2 - (-2)

m = 5 - 2 / 2 + 2

m = 3/4

Answer: When the addition of two or more equations leads to the elimination of one of the variables.

Step-by-step explanation:

When we have a system of equations, the addition method seems to be useful only when adding the equations will lead to the elimination of one of the variables:

An example of this can be, for the variables x and y:

3*x + x*y - 2*y = 3

x^2 + x*y - 2y = 42

now we can "add" (actually subtract) the equations and get (eq2 minus eq1)

(x^2 + x*y - 2y) - (3*x + x*y - 2*y ) = 42 - 3

x^2 - 3*x = 39

x^2 - 3*x - 39 = 0

And now we can solve it for x, and then find the value of y.

When we move to the left on the number line the numbers are decreasing, which means we're subtracting. When we move to the right, the numbers are increasing, which means we're adding.

To find 3 units to the left of -15 we just need to subtract 3 units from - 15.

3 units to the left of -15 is -18.

To find 2 units to the right of -12 we just need to add 2 units from - 12.

The difference between the elements on the number line is 1 unit, and using the first statement, we have that the blanks are

-22 -21 -20 -19 -18 -17 -16

Answer: There are  62 tricycles in the shop.

Step-by-step explanation:

Given: Number of wheels in a bicycle = 2

Number of wheels in a tricycle = 3

Let x = Number of bicycles , y = Number of tricycles.

As per given , we have

x+y =120       (i)

2x+3y=302       (ii)

Multiplying 2 on both sides of (i)

2x+2y=240      (iii)

Subtract (iii) from (ii) , we get

y= 62

Put value of y in (i) , we get

\(x+62=120\\\\\Rightarrow\ x=120-62\\\\\Rightarrow\ x= 58\)

Hence, there are 58 bicycles and 62 tricycles in the shop.

Step-by-step explanation:

The required function y = 7 cos (2π * 0.1 * x) and period of the function is 10 seconds, which is the time it takes for one complete cycle of the wave.

he cosine function can be used to model periodic motion, and its general form is:

y = A cos (Bx + C) + D

where A is the amplitude, B is the frequency, C is the phase shift, and D is the vertical shift.

In this case, we know that a 14 in. wave occurs every 10 s, so we can use this information to find the frequency, which is the reciprocal of the period. The period is the time it takes for one complete cycle of the wave, which in this case is 10 s.

Therefore, the frequency is:

\(f = \frac{1}{T}=\frac{1}{10} = 0.1 Hz\)

We can also see that the amplitude of the wave is 7 inches, since the wave has a height of 14 inches from its highest point to its lowest point.

Now we can write the function that models the height of the particle in inches y as it moves in seconds x:

y = 7 cos (2π * 0.1 * x)

Here, the frequency is expressed in radians per second (2π * 0.1 = 0.2π), since the cosine function takes radians as its argument. The phase shift and vertical shift are both zero in this case, since the wave starts at its highest point and has no vertical shift.

Therefore, the period of the function is 10 seconds, which is the time it takes for one complete cycle of the wave.

Predictions involving the use of more than one dependent variable and the sampling technique related to assigning samples to a certain number of groups utilize multiple regression and cluster sampling respectively.

Regression models are used to make prediction models based on a set of a given independent and dependent variables. When the dependent variables to be used is more than one, then a multiple regression model should be adopted. In the case of just one dependent variable, the model adopted ls a linear regression model.

Hence, the multiple regression technique should be adopted.

Cluster sampling technique involves the used of a certain number of points called clusters upon which samples or variables of related elements are grouped together. Therefore, in these scenario, the 10 showing of the fim are clusters and attendees related to each showings are the cluster samples.

Answer:

(2.5, -3.25)

Step-by-step explanation:

In relictions, only one value in the coordinate changes, either the x or y value depending on the type of reflection

First, reflect the coordinate over the x-axis.

Reflections across the x-axis is basically folding the graph across the x-axis. If you fold the graph across the x-axis, you notice that only the y-value is changing to be the opposite sign.

Basically in a reflection of the x-axis, the coordinates (x, y) change to (x, -y)

Therefore, (-2.5, -(3.25)) turns into (-2.5, -3.25)

Next, reflect the coordinate (-2.5, -3.25) across the y-axis. Similarly as above, reflections across the y-axis is like folding the graph on its y-axis. If you do so, you notice that only the x-value changes while the y-values stays the same.

Therefore (x,y) turns into (-x, y)

So, (-2.5, -3.25) = (-(-2.5), -3.25) = (2.5, -3.25)

Answer:

\((2.5 , -3.25)\)

When you do a reflection, the negative values turn positive and the positive values turn negative.

Currently in the graph, the ordered pair is (-2.5, 3.25).

So, we will flip the two around.

Now, we will put them into an ordered pair again.

Our new ordered pair will be (2.5, -3.25)

Answer:

James town is 5 meters higher than Takoradi​ .

Step-by-step explanation:

Given:

Height of James town = 2 meters below sea level

Height of Takoradi town = 7 meters below sea level

To find:

How much higher is James town that Takoradi = ?

Solution:

As we can see the standard of height is how much the town is below the sea level.

So, the height of town having lesser value will be at a higher level.

Value of Height of James town is lesser than that of Takoradi town.

Therefore, James town is at a higher level.

Difference of height = 7 meters - 2 meters = 5 meters

So, the answer is:

James town is 5 meters higher than Takoradi.

The simplified expression of x(3x + 5)-5(2x - 1) is 3x² - 5x + 5

From the question, we have the following parameters that can be used in our computation:

x(3x + 5)-5(2x - 1)

Open the brackets

So, we have

3x² + 5x - 10x + 5

Evaluate the like terms

So, we have

3x² - 5x + 5

Hence, the simplified expression is 3x² - 5x + 5

Answer:

a) Ub = 0,069

b)  CI 99 %  = ( 0,0287 ; 0,069 )

c) n = 2536

Step-by-step explanation:

Confidence Interval (CI) for proportion is

p₀  ±  z(c) * √ ( p₀*q₀ ) /n

Where     p₀  is the sample proportion

n = size of the sample

and z(c)   is z score for the significance level α

As    CI  = 99 %       α = 1%      α = 0,01      α/2 = 0,005

from z-table we find   z(c) = 2,57

p₀ = 12/300      p₀ = 0,04  ;    

n*p₀ = 12  > 10 and  n*q₀  = 300*0,96        n*q₀ = 288 > 10

We can use normal distribution as a valid  aproximation of binomial distibution

Then     z(c) = 2,57

a) upper bound for CI     Ub

Ub = p₀ + z(c) * √ p₀q₀/300

Ub = 0,04  +  2,57 * √ (0,04*0,96)/300

Ub = 0,04 + 0,0113

Ub = 0,069

b) CI at 99%  is

CI  = p₀  ±  z(c) * √ ( p₀*q₀ ) /n

we have already calculated the Ub = 0,069

the Lower bound would be   Lb = 0,04 - 0,0113

Lb = 0,0287

Then     CI 99 %  = ( 0,0287 ; 0,069 )

c) If      CI ≤ 0,02 we can find the minimun n value with the equation:

p₀  ±  z(c) * √ ( p₀*q₀ ) /n = CI   or    p₀  -  z(c) * √ ( p₀*q₀ ) /n = 0,01

For symmetry respect to p₀

z(c) *√ (p₀*q₀) / n  = 0,01

Solving for n

z(c) * √ ( p₀*q₀ ) /n = 0,01

2,57 * √ (0,04*0,96)/n  =  0,01

2,57 * √ 0,0384/n = 0,01

2,57 = 0,01/√ 0,0384/n

Squaring both sides of the equation

6,6049 = (0,01)² *n / 0,0384

0,0384*6,6049 / 0,0001  = n

n = 2536

(2x - 3)

Because it becomes zero when x = 3/2.

We know that the function f(x) has zeros at x = -1/2 and x = 3/2.

And we want to see which ones of the given expressions can be a factor of the function.

If the function becomes zero at these values, then the factors need to become zero at one of these two values.
