If you are referring to the central angle, it would be 41 degrees.

Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti

julsineya [31]

Answer:

see below

Step-by-step explanation:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage

After first dose residual drug amount is:

d= 500*0.045= 22.5 mg

After second dose:

d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum residual drug will be in the body:

d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

500+19*22.5= 927.5 mg

Calculate interior angle of a regular 15 sided polygon

AleksAgata [21]

Answer:

156°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 15 , then

sum = 180° × 13 = 2340°

interior angle = $\frac{sum}{n}$ = $\frac{2340}{15}$ = 156°

Does the residual plot show that the line of best fit is

Iteru [2.4K]

Answer:

$e_1 = 3.5-4.06= -0.56$

$e_2 = 2.3-2.09= 0.21$

$e_3 = 1.1-0.12= 0.98$

$e_4 = -2.2-(-1.85)= -0.35$

$e_5 = -4.1-(-3.82)= -0.28$

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.

Step-by-step explanation:

The correct formula for the residuals is given by:

$e_i =y_i -\hat y_i$

Who represent the observed value minus the predicted. We can find the individual residuals and we got:

$e_1 = 3.5-4.06= -0.56$

$e_2 = 2.3-2.09= 0.21$

$e_3 = 1.1-0.12= 0.98$

$e_4 = -2.2-(-1.85)= -0.35$

$e_5 = -4.1-(-3.82)= -0.28$

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.

Oliver injured his leg while playing football. Fortunately, he has a health insurance policy. He has a deductible of $2,000, and

yKpoI14uk [10]

Answer:

The Answer is:

Step-by-step explanation:

First, find the 20% that he must pay:

$3,500 * .20 = $700.

The remaining balance is:

$3,500 - $700 = $2,800

He already paid $1,000 of his deductible of $2,000. He has $1,000 left to pay.

Add that to the $700 to get:

$1,000 + $700 = $1,700 out of pocket.
