Answer:

Step-by-step explanation:

(ab)^n = a^n*b^n

so (-a)^n = (-1)^n*a^n

a^(-n) = 1/a^n

a^0 = 1 if a is not 0

9. 3^(-2)

= 1/3^2

= 1/9

11. (-5)^(-2)

= (-1)^-2*5^(-2)

= (1/(-1)^2)*(1/(5^2))

= 1/1*1/25

= 1/25

15. -3^0 = 1

17. 1/2^0

= 1/1

=1

26. k^(-4)*j^0

=(1/k^4)*1

=1/k^4

36. 7*s^0*t^(-5) / 2^(-1)*m^2

= 7*1*(1/t^5) / (1/2)*m^2

= 2*7 / t^5*m^2

= 14 / t^5*m^2

Using proportions, it is found that the total cost for beverages will be of $552.00.

A proportion is a fraction of a total amount.

In this problem, there will be a total of 46 people, and each will spend $12.00 on beer and wine, hence:

46 x $12.00 = $552.00.

The total cost for beverages will be of $552.00.

6g + 18 is an equivalent expression when the distributive property is used.

Answer:

23

Step-by-step explanation:

Since 12 and 18 are both divisible by 3, you would divide them by 3. Then, you are left with the fraction 46 . But, since 4 and 6 are both divisible by 2, you would do that. Finally, you end up with 23 with is in the lowest terms.

By using x-method we got that factorization [tex]x^2-25[/tex]  is (x+5)(x-5)

factorization is writing a expression as a product of several factors.

So Given polynomial is

[tex]x^2-25[/tex]

Now we will factorise  this using x method

Here a=1     b=0 and c= -25

so ac=-25

Now We will write -25 at the top.

and 0 at the bottom.

No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.

Now we can write equation as

[tex]x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)[/tex]

Answer:

The 90% confidence interval would be given by (63.330;81.070)

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Let put some notation

x=left arm , y = right arm

x: 175 169 182 146 144

y: 102 101 94 79 79

Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13

Answer:

r=14

Step-by-step explanation:

7r+6=8r-8

14=r

r=14

Answer:

r = 14

Step-by-step explanation:

Since both angles are equivalent to each other solve for r:

7r + 6 = 8r - 8 (subtract 6 from -8)

7r = 8r - 14 (subtract 8r from 7r)

-r = -14 (divide each side by -1)

r = 14

Then plug the value of r (14) back into both parentheses:

7 * 14 + 6 = 104°

8 * 14 - 8 = 104°

The final answer is r = 14, and both angles equal to 104°

The expression which is equivalent to the provided complex fraction is equal to the expression,

[tex]{\dfrac{-4x+7}{2(x-2)}}[/tex]

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The expression given in the problem is,

[tex]\dfrac{\dfrac{3}{x-1}-4}{2-\dfrac{2}{x-1}}[/tex]

Let the expression which is equivalent to the above expression is f(x). Therefore,

[tex]f(x)=\dfrac{\dfrac{3}{x-1}-4}{2-\dfrac{2}{x-1}}[/tex]

Take the LCM (x-1) in the numerator and denominator as,

[tex]f(x)=\dfrac{\dfrac{3-4(x-1)}{x-1}}{\dfrac{2(x-1)-2}{x-1}}[/tex]

Simplify the expression and cancel out the (x-1) from both the fraction as,

[tex]f(x)={\dfrac{3-4(x-1)}{2(x-1)-2}}\\f(x)={\dfrac{3-4x+4}{2x-2-2}}\\f(x)={\dfrac{-4x+7}{2(x-2)}}[/tex]

Hence, the expression which is equivalent to the provided complex fraction is equal to the expression,

[tex]{\dfrac{-4x+7}{2(x-2)}}[/tex]

Equivalent expressions are expressions of equal values

The equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

The first expression has been solved.

So, we have the following expressions

4x−7y−5z+6 and -3x−8y−4−87z

4x−7y−5z+6

We have:

4x-7y-5z+6

Rewrite as:

4x+ (y - 8y) + (2z-5z) +6

-3x−8y−4−87z

We have:

-3x−8y−4−87z

Rewrite as:

3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

Hence, the equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)
