Answer:

52

Step-by-step explanation:

answer = fifty two

x = 52

Answer:

X+90+90+128=360(total sum of quadrilateral)

X+180+128=360

X+308=360

X=360-308

X=52

Using the z-distribution, as we are working with a proportion, it is found that:

A. Yes, the data provides convincing statistical evidence that Swedish men who would be classified into group A have a lower probability of stroke than Swedish men who would be classified into group B.

B. Considering that the data provides statistical evidence, the conclusion was appropriate.

At the null hypothesis, it is tested if the proportions are the same, that is:

[tex]H_0: p_A - p_B = 0[/tex]

At the alternative hypothesis, it is tested proportion A is less than proportion B, that is:

[tex]H_1: p_A - p_B < 0[/tex]

For each sample, they are given by:

[tex]p_A = \frac{458}{9250} = 0.0495, s_A = \sqrt{\frac{0.0495(0.9505)}{9250}} = 0.0023[/tex]

[tex]p_B = \frac{543}{9250} = 0.0587, s_B = \sqrt{\frac{0.0587(0.9413)}{9250}} = 0.0024[/tex]

Hence, for the distribution of differences, we have that:

[tex]\overline{p} = p_A - p_B = 0.0495 - 0.0587 = -0.0092[/tex]

[tex]s = \sqrt{s_A^2 + s_B^2} = \sqrt{0.0023^2 + 0.0024^2} = 0.0033[/tex]

It is given by:

[tex]z = \frac{\overline{p} - p}{s}[/tex]

In which p = 0 is the value tested at the null hypothesis.

Hence:

[tex]z = \frac{\overline{p} - p}{s}[/tex]

[tex]z = \frac{-0.0092 - 0}{0.0033}[/tex]

[tex]z = -2.77[/tex]

Item a:

Considering a left-tailed test, as we are testing if the proportion is less than a value, with the standard significance level of 0.05, the critical value is of [tex]z^{\ast} = -1.645[/tex].

Since the test statistic is less than the critical value, it is found that yes, the data provides convincing statistical evidence that Swedish men who would be classified into group A have a lower probability of stroke than Swedish men who would be classified into group B.

Item b:

Considering that the data provides statistical evidence, the conclusion was appropriate.

graph{x^3+2x^2-3x [-10, 10, -5, 5]}

Answer:

-3/5

Step-by-step explanation:

I used the KCF, or keep, change, flip, method for this.

The original problem is -2/5 divided by -2/3

We keep the first fraction - -2/5

change the sign to multiplication

and flip the second fraction - 3/2

so, -2/5 x 3/2

and then check for where we can simplify, we can in this instance:

-1/5 x 3/1

and then multiply across

-3/5

Answer:

we need the figure, where is it

»(4x - 2y)(3x + 5y)

»4x(3x + 5y) + (-2y)(3x + 5y)

»12x² + 15xy - 6xy - 10y²

»12x² + 9xy - 10y²

so, ABC is :

Check the picture below.

Taking into account the definition of a system of linear equations, the solution t=14 represents a viable time that the trains are side by side.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

The system of equations to be solved is

[tex]\left \{ {{y=14t^{2} } \atop {y=96t+1400}} \right.[/tex]

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the first equation in the second you get:

14t²= 96t +1400

Solving:

14t²- 96t -1400=  0

Being this a quadratic function of the form ax² + by +c, then it can be solved by: [tex]x1,x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

In this case, being a=14, b=-96 and c=-1400, the equation is solved by:

[tex]t1=\frac{-(-96)+\sqrt{(-96)^{2} -4x14x(-1400)} }{2x14}[/tex]

[tex]t1=\frac{96+\sqrt{9216 +78400} }{28}[/tex]

[tex]t1=\frac{96+\sqrt{87616} }{28}[/tex]

[tex]t1=\frac{96+296}{28}[/tex]

[tex]t1=\frac{392}{28}[/tex]

t1=14

and

[tex]t2=\frac{-(-96)-\sqrt{(-96)^{2} -4x14x(-1400)} }{2x14}[/tex]

[tex]t2=\frac{96-\sqrt{9216 +78400} }{28}[/tex]

[tex]t2=\frac{96-\sqrt{87616} }{28}[/tex]

[tex]t2=\frac{96-296}{28}[/tex]

[tex]t2=\frac{-200}{28}[/tex]

t2= -7.14

Since time cannot be a negative value, the solution t=14 represents a viable time that the trains are side by side.

Answer:

2x+4 or 2(x+2)

Step-by-step explanation:

I'm not very confident that I can give you a clear explanation while typing, but you can factor the equation which is one way how to do this.

2x^2 + 10x+12 = 2(x^2+5x+6)

                       = 2(x(x+3) + 2(x+3))

                       = 2(x+3)(x+2)

With that answer, you divide it by x+3 and get 2(x+2) or 2x+4

Based on the statements provided, Barry will a have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.

Logical reasoning in mathematics is the process of using rational and critical thinking abilities to arrive at a conclusion about a problem.

Since Barry have at least one dog breed, the possible breeds of dogs that Barry have can be determined as follows:

Statement 1: If I have a Labrador but not a Staffie, I also have a Collie

Statement 2: I either have both a Collie and a Staffie or neither.

Statement 3: If I have a Collie, then I also have a Labrador.

Therefore, Barry will have a Labrador, a Collie and a Staffie at home if he has at least one dog breed.

Answer:

{x,y}={-4,-1}

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 3x = 4y - 8

[2] x = 4y/3 - 8/3

// Plug this in for variable x in equation [1]

[1] 2•(4y/3-8/3) + 5y = -13

[1] 23y/3 = -23/3

[1] 23y = -23

// Solve equation [1] for the variable y

[1] 23y = - 23

[1] y = - 1

// By now we know this much :

x = 4y/3-8/3

y = -1

// Use the y value to solve for x

x = (4/3)(-1)-8/3 = -4

Solution :

{x,y} = {-4,-1}

The equation that represents the linear function is y = 2x.

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let us assume that from the table, we get the data with points (0, 0) and (2, 4). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{4-0}{2-0} (x-0)\\\\y=2x[/tex]

Answer:

A parallelogram is a four sided shape, so this means that the total sum of interior angles is equal to 360 degrees.

It also has two sets of matching angles, therfore if it says one is 155 degrees it must have one more that is also 155 degrees.

This means 2 x 155= 310, 360 - 310 = 50 degrees remaining. This 50 degrees would be shared between the remaining two angles as they must be a matching pair also. 50 / 2=25.

This parallelogram has two angles of 155 and two of 25. Degrees.
