Answer:

if you divide 10 by 8 it should be 10/8 so a

Hope This Helps!!!

Answer: A

Step-by-step explanation: Step 3 is incorrect as it should be 10/8 (or 5/4 simplified.) When we have 8x = 10, we are looking at what number "x" multiplied by 8 gives 10. Meaning we need to have 8(?) = 10. So, to find out what x is, we just divide by 8 from both sides. Since 8x/8 cancels out and becomes just x, we get x = 10/8 since we are dividing 10 by 8. We get 5/4 simplified or 10/8 unsimplified.

The value of x in the triangle is (a) 22

The complete question is in the attached image.

From the attached image of the triangle, we have:

[tex]\sin(45) = \frac{x}{22\sqrt 2}[/tex]

Evaluate sin(45)

[tex]\frac{1}{\sqrt 2} = \frac{x}{22\sqrt 2}[/tex]

Solve for x

[tex]x = \frac{22\sqrt 2}{\sqrt 2}[/tex]

Divide

x = 22

Hence, the value of x is (a) 22

[tex]e = \cos(39) \times 22[/tex]

[tex] \sin(39) = \frac{d}{22} [/tex]

Answer:

The answer is c) 73

Step-by-step explanation:

The angle 146 and (-39 + x) lie on the same line, so that means their sum is 180 degrees because a straight line has 180 degrees.

180 = 149 - 39 + x

180 = 107 + x

180 - 107 = x

73 = x

Answer:

73

Step-by-step explanation:

The two angles form a straight line  and a straight line is 180 degrees

-39+x + 146 = 180

Combine like terms

107 +x = 180

Subtract 107 from each side

107+x-107 = 180-107

x =73

The computation shows that the number of ways that this can be done is 64.

Step-by-step explanation:

2x-15y = 117 is the simplified form of the equation.

Equation : In a mathematical sentence, if two expressions are present in left and right side of an equal sign, then the mathematical sentence is called an equation.

If, a, b, c be integers and x is x-intercept & y is y-intercept, then ax+by=c is called equation of line.

Given that, the equation of the line that passes through the points (-9,-9)(−9,−9) and (6,-7)(6,−7).

Now, (-9,-9) & (6, -7) have a line through them with slope = (-9+7)/(-9-6) = 2/15

Therefore, (y+7) = 2/15×(x-6)

⇒ y+7 = 2x/15 - 4/5

⇒ y = 2x/15 - 4/5 - 7

⇒ y = 2x/15 -39/5

This is the equation in slope intercept form.

Multiplying the equation with 15, we get,

⇒ 15y = 2x-117

⇒ 2x-15y = 117 , which is the simplified form of the equation.

Using the margin of error for the z-distribution, the sample sizes are given as follows:

a) 822.

b) 1068.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

We have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

Item a:

The estimate is of [tex]\pi = 0.26[/tex], hence we solve for n when M = 0.03.

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.26(0.74)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.26(0.74)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.26(0.74)}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.26(0.74)}}{0.03}\right)^2[/tex]

n = 821.2

A sample of 822 is needed.

Item b:

No prior estimate, hence [tex]\pi = 0.5[/tex].

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.5(0.5)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.5(0.5)}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.5(0.5)}}{0.03}\right)^2[/tex]

Step-by-step explanation:

So if you look at the equation, you'll notice it's being multiplied by it's conjugate which can be expressed as: x+a and x-a. See how only the sign changes? Well if remember the differences of squares, it looks like that, because it is. Essentially the difference of squares says that: [tex]a^2-b^2=(a-b)(a+b)[/tex]. So expanding this out will result in [tex](5a^3)^2-(2)^2[/tex] which simplifies to: [tex]25a^6-4[/tex]. If you're confused on how I got 25a^6. Try to think of a^3 as three a's rather than simply an exponent. and since it has a coefficient of 5. 5a^3 is the same as (5 * a * a * a). Now if you square this you have (5 * a * a * a) * (5 * a * a * a). So if you group like terms you'll end up with 6 a's being multiplied by each other (which can be expressed as a^6) and 5 * 5 which is 25.

The multiplication can be transformed into the difference of squares using the rule:(a−b)(a+b)=a²-b² . Gets the square of 2.

(5a³)²-4

Expand (5a³)².
