which of the following choices is equivalent to the expression below?
can someone explain how to do it?

Answer:

Linda has ridden 90% of the course

Step-by-step explanation:

To find the percentage the formula is

distance ridden so far/total distance X 100

54/60 X 100

= 0.9 X 100

= 90

=90%

Therefore Linda has ridden 90% of the course.

So essentially an adjacent angle is when two angles have a common side and a common vertex.

So knowing that we can determine from the picture all the adjacent angles:

D) <2 and <3 are adjacent angles

E) <1 and <3 are adjacent angles

F) <1 and <5 are adjacent angles

I hope this helps.

Answer:

$12,000

Step-by-step explanation:

2% for 5 years is 10% in total. if after the 5 years she gotta pay 1200, this mean 0.1p=1200

multiply 10 on both sides to find p, or principal.

p=12000

Answer:

$12,000

Step-by-step explanation:

P = 1200 / ( 0.02 × 5 ) = 12000

P = $ 12,000.00

Answer:

It will be withheld $75 for federal income.

Step-by-step explanation:

Proportions

Assuming the federal income tax is proportional to the earnings, we can establish the following relationship between the income tax (T) and the earnings (E):

T = k.E

Kimberly earned E=$500 and paid T=$50 for federal income tax, With this information, we can calculate the value of k:

50 = k ( 500)

k = 50 / 500

k = 0.1

The model is now:

T = 0.1*E

If Kimberl earns $750 next month, the tax will be:

T = 0.1*($750)

T = $75

It will be withheld $75 for federal income.

Answer:

(19x - 1)° = 56°

(13x - 5)° = 34°

Step-by-step explanation:

Property of the interior angles of a triangle:

Sum of interior angles of a triangle is 180°.

Therefore, sum of angles of the given right triangle will be,

(19x - 1)° + (13x - 5)° + 90° = 180°

32x - 6 + 90 = 180

32x = 96

x = 3

(19x - 1)° = 19×3 - 1 = 56°

(13x - 5)° = 13×3 - 5 = 34°

Answer:

$26.80

Step-by-step explanation:

multiply 1.79 by 5 and you get 8.95

multiply 1.19 by 15 now because there are 15 uncounted bags left and you get 17.85

add together and you get 26.8. she spent 26.8 dollars on candy

Answer: A. x + y = 75 B. She spends 25 minutes running and 50 minutes dancing every day. C. Yes it is.

Step-by-step explanation: B. She spends 25 minutes running and 50 minutes dancing every day, because if she dances for 25 more minutes then she runs then we can minus 25 from 75 which we get 50. Then we take the 50 a divide it by 2 because of the two categories dancing and running. So we know she spends 25 minutes running then 25 minutes dancing but we need to add the 25 minutes to dancing. So she spends 25 minutes running and 50 dancing. C. Yes it is because she already dances for 50 minutes a day so all she needs to do is workout for 10 minutes less so 65 minutes one day.

A system of linear equation consists of multiple linear equations

(a) A pair of linear equations

She dances and runs for 75 minutes.

So:

[tex]\mathbf{x + y = 75}[/tex]

She dances 25 minutes more than she runs.

So:

[tex]\mathbf{y = 25 + x}[/tex]

So, the system of linear equations is: [tex]\mathbf{x + y = 75}[/tex] and [tex]\mathbf{y = 25 + x}[/tex]

(b) The time she spends running every day

Substitute 25 + x for y in [tex]\mathbf{x + y = 75}[/tex]

[tex]\mathbf{x + 25 + x = 75}[/tex]

Subtract 25 from both sides

[tex]\mathbf{2x = 50}[/tex]

Divide both sides by 2

[tex]\mathbf{x = 25}[/tex]

Hence, she spends 25 minutes running

(c) Is it possible to dance 45 minutes each day

We have:

[tex]\mathbf{y = 25 + x}[/tex]

So:

[tex]\mathbf{y = 25 + 45}[/tex]

[tex]\mathbf{y = 70}[/tex]

This means that, she has to spend less minute running and dancing.

Answer:

The decision rule is  

  Reject the null hypothesis

The test statistics is [tex]t = -2.699[/tex]

Step-by-step explanation:

From the question we are told that

   The first sample size is  [tex]n_1 = 15[/tex]

   The mean at first deployment is  [tex]\= x _1 = \$ 150 000[/tex]

   The standard deviation is  [tex]s_1 = \$ 40000[/tex]

    The second sample size is [tex]n_2 = 25[/tex]

    The mean at second deployment is  [tex]\= x_2 = \$ 180000[/tex]

    The standard deviation is  [tex]s_2 = \$ 30 000[/tex]

The null hypothesis is  [tex]H_o : \mu_1 = \mu_2[/tex]

The alternative hypothesis is  [tex]H_a : \mu_1 \ne \mu_2[/tex]

   The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the degree of freedom is mathematically represented as

      [tex]df =n_1 + n_2 -2[/tex]

=>   [tex]df =40 -2[/tex]

=>   [tex]df =38[/tex]

Generally the pooled variance is mathematically represented as

      [tex]s_p^2 = \frac{x(n_1 -1) s_1^2 + (n_2 - 1)s_2^2}{df}[/tex]

=>   [tex]s_p^2 = \frac{(15 -1) 40000^2 + (25 - 1)30000^2}{38}[/tex]

=>   [tex]s_p^2 = 1.1579 * 10^{9}[/tex]

Generally the test statistics is mathematically represented as

      [tex]t = \frac{ \= x_1 - \= x_2 }{\sqrt{s_p [\frac{1}{n_1} + \frac{1}{n_2} ]} }[/tex]

=>   [tex]t = \frac{ 150000 - 180000 }{\sqrt{1.11579 *10^{9} [\frac{1}{15} + \frac{1}{25} ]} }[/tex]

=>   [tex]t = -2.699[/tex]

Generally from the  t distribution table the probability corresponding to the t statistics value to the left is  

     [tex]t_{-2.699 , 38} = 0.00516046[/tex]

Generally the p -value is mathematically represented as

     [tex]p-value = 2* t_{-2.699, 38}[/tex]

=>  [tex]p-value = 2* 0.00516046[/tex]

=>  [tex]p-value = 0.01032[/tex]

From the obtained value we see that the  [tex]p-value < \alpha[/tex]  hence

   The decision rule is  

  Reject the null hypothesis
