..................

The number of solutions, an equation can have is independent of the position of the variable.

An equation can have:

Irrespective of where the variable appears

Take for instance:

[tex]x + 5 = 17 - x[/tex]

To solve this, we start by collecting like terms

[tex]x + x = 17- 5[/tex]

[tex]2x = 12[/tex]

Divide both sides by 2

[tex]x = 6[/tex]

In the above scenario, the variable (x) appears on both sides of the equation and the equation has 1 solution.

Another case scenario is as follows:

[tex]x + 5 = x[/tex]

Collect like term

[tex]x - x = -5[/tex]

[tex]0 = -5[/tex]

The above scenario shows that the equation has no solution and the variable (x) appears on both sides of the equation.

So, we can conclude that, an equation can have:

Irrespective of where the variable appears

Hence, option (a) is correct.

Answer:

The 95% confidence interval [tex]0.57 < p <0.63[/tex]

The 90% confidence interval  [tex]0.5748 < p <0.6252[/tex]

The 90% confidence interval has the smaller margin of error.

This makes sense because the 90% confidence interval is narrower and more precise(i.e a decreased error band  ) than the 95% confidence interval

95% confidence interval is more likely to contain the true percentage

This is because 95% confidence interval signify's a higher confidence  of containing the true percentage than the 90% confidence interval  

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  1019

    The  sample proportion is  [tex]\r p = 0.60[/tex]

Given from the question that the confidence level is 95% then the level of significance is mathematically represented as

         [tex]\alpha = (100 - 95)\%[/tex]

        [tex]\alpha = 0.05[/tex]

Generally the critical value of  [tex]\frac{\alpha }{2}[/tex] obtained from the normal distribution table is  

    [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Generally the margin of error is mathematically represented as

         [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\r p (1 - \r p )}{n} }[/tex]

=>     [tex]E = 1.96 * \sqrt{\frac{0.60 (1 - 0.60 )}{1019} }[/tex]

=>    [tex]E = 0.030[/tex]

Generally the 95% confidence interval is mathematically represented as

         [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.60 - 0.030 < p <0.60 + 0.030[/tex]

        [tex]0.57 < p <0.63[/tex]

This interval means that there is 95% chance that the true percentage will be in this interval

Given from the question that the confidence level is 90% then the level of significance is mathematically represented as

         [tex]\alpha = (100 - 90)\%[/tex]

        [tex]\alpha = 0.10[/tex]

Generally the critical value of  [tex]\frac{\alpha }{2}[/tex] obtained from the normal distribution table is  

    [tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]

Generally the margin of error is mathematically represented as

         [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\r p (1 - \r p )}{n} }[/tex]

=>     [tex]E = 1.645 * \sqrt{\frac{0.60 (1 - 0.60 )}{1019} }[/tex]

=>    [tex]E = 0.0252[/tex]

Generally the 90% confidence interval is mathematically represented as

         [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.60 - 0.0252 < p <0.60 + 0.0252[/tex]

        [tex]0.5748 < p <0.6252[/tex]

This interval means that there is 90% chance that the true percentage will be in this interval

From the calculation the 90% confidence interval has the smaller margin of error.

This makes sense because the 90% confidence interval is narrower and more precise(i.e a decreased error band  ) than the 95% confidence interval

Generally the confidence interval that is more likely to contain the true percentage  of all American adults who have used the Internet to obtain medical information in the past month is the 95% confidence interval ,

This is because it signify's a higher chance of containing the true percentage than the 90% confidence  

Answer:

x = 3, y = 8.

Step-by-step explanation:

So if x = 3, and y = ?,

Its the same as if y = -4 when x = -9.

Find the difference between 3 and -9.

3 - (-9) = 12 because when you subtract a negative number, the second negative sign flips the direction your going on the number line. We just found the absolute value. Now the oppisite of 12 is -12. Final answer is -12.

Let's do the same thing to the -4, but subtract -12.

-4 - (-12) = 8.

So if x = 3, y = 8

Answer:  321q = z

This is the same as z = 321q

The term "product" means "result of multiplying two or more values"

For example, the product of 2 and 3 is 2*3 = 6

Writing 321q is the same as 321*q, but we often leave out the multiplication sign. You could say q*321, but convention usually has the number come first then the variable second. The 321 is the coefficient.

Answer:

X is 67 and the measure of the angle is 52 and Y is 32 and the measure of the angle is 128 degrees

Step-by-step explanation:

Answer:

X=50

Step-by-step explanation:

Because the top and bottom angles are formed by 2 intersecting lines, we know that the angles are equivalent to each other via the vertical angle theorem. This allows us to set the following equation:

[2(x+10)]=(3x-30)

You would then distribute the 2 on the left side to get

2x+20=3x-30

Then, simply combine like terms.

20+30=3x-2x

Simplify.

50=x

The answer is therefore 50.

The 15th term is 103

Step-by-step explanation:

Arithmetic Sequence

An arithmetic sequence is a list of numbers with a definite pattern by which each term is found by adding or subtracting a fixed quantity to the previous term. If n is the number of the term, then:

[tex]a_n=a_{n-1}+d[/tex]

Where d is called the common difference. If we know the first term, the nth term is calculated by:

[tex]a_n=a_1+(n-1)*d[/tex]

The question asks us to find the term n=15 of an arithmetic sequence with a common difference d=7 and first term a1=5.

Applying the formula above:

[tex]a_{15}=5+(15-1)*7[/tex]

[tex]a_{15}=5+14*7[/tex]

[tex]a_{15}=5+98=103[/tex]

The 15th term is 103

Answer:

y = 2(x + 3)(x + 1)

Step-by-step explanation:

Use the formula y = a(x-b)(x-c)

b and c are the x-intercepts

The x-intercepts in this function are -3 and -1

y = a(x+3)(x+1)

substitute the point (-2, -1)

-2 = a(-2 + 3)(-2 + 1)

-2 = a(1)(-1)

-2 = -a

a = 2

y = 2(x + 3)(x + 1)
