Answer:

($8.16 is the taxes) ($110 is how much she paid without taxes)

Step-by-step explanation:

Susie bought 4 pairs of pants. Her total bill, including tax was

$110.16. If each pair of pants cost $25.50 before tax was added,

what tax rate did Susie pay on the pants?

Susie buys 4 pairs of pants. And individually each pair costed $25.50. What I did was multiply 25.50 by 4, and I got 102. Now subtract the 110.16 and 102 and u get 8.16 which that's the taxes.

Solve for kkk.
Likurg_2 [28]

Answer:

k=\frac{3}{2}

Step-by-step explanation:

Given:

\frac{k}{4}=\frac{3}{8}

To find: value of k

Solution:

Cross-multiplying is a method in which the numerator of each (or one) side is multiplied by the denominator of the other side.

\frac{k}{4}=\frac{3}{8}

On cross-multiplication, the equation becomes k\times 8=4\times 3

8k=12

Divides both sides by 8

\frac{8k}{8}=\frac{12}{8}\\k=\frac{12}{8}=\frac{3}{2}

kramer

Answer: We concluded that annual income and education level are not independent.

Step-by-step explanation:

For the given situation, the null and alternate hypothesis can be formulated as:

H_0: annual income and education level are independent.

H_a: annual income and education level are not independent.

Given,  the value of test statistic is 24.32 and the critical value of test statistics is 13.32.

i.e. the test statistic value is greater than the critical value, thus we have enough evidence to reject the null hypothesis.

Therefore, we reject null hypothesis .

So , we concluded that annual income and education level are not independent.

Twice a number plus five is same as five times the number minus sixteen , the number is ____.
madam [21]

Answer:

7

Step-by-step explanation:

solving algebraically:

(x = the unknown number)

(our goal is to isolate x/get x by itself)

  2x + 5 = 5x - 16     {equation written out}

 -2x         -2x

        5 = 3x - 16

   + 16        + 16

      21 = 3x

    ÷3   ÷3

      7 = x

check:

(2)(7) + 5 = (5)(7) - 16

14 + 5 = 35 - 16

19 = 19

hope this helps!!
