A. because the 9th and 10th values are in the middle so you would have to take their average to get the middle number

Answer: The correct option is

(A) The mean of the 9th and 10th values.

Step-by-step explanation: Given that there are 18 values in a data set in order from smallest to largest.

We are to find the median of the data set.

We know that

if a data set has n values, then the median value is given by

$(i)~\dfrac{n+1}{2},$ if n is odd.

$(ii)\textup{the mean of }\dfrac{n}{2}~\textup{and}~\dfrac{n}{2}+1$ if n is even.

In the given situation, we have

n = 18, which is even.

So, the median values are given by the mean of

$\dfrac{18}{2},~~\dfrac{18}{2}+1\\\\=9,~~10.$

Therefore, the required median value is the mean of 9th and 10th values.

Option (A) is CORRECT.

write the equation of the line in slope intercept form with the given conditions (slope = 3 and passes through (1,-3))

cupoosta [38]

Answer:

Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)

Step-by-step explanation:

m=3 , x1=1 , y=-3

y-(-3)=3(x-1)

y+3=3x-3 subtract 3 from both sides

y=3x-6 the answer in the slope-intercept form y=mx+b

MAVERICK [17]

Answer: Hence, this investment would be worth of $366.756

Step-by-step explanation:

Since we have given that

Amount he invests = $350

Rate of interest compounded quarterly = 1.5%

Number of years = 50 years = 1.25 quarters

As we know the formula for "Compound Interest ":

$Amount=P(1+\frac{r}{400})^n\\\\Amount=350(1+\frac{1.5}{400})^{12}\\\\Amount=\$366.07$

For remaining half year, we first find the interest with using the above amount as principal amount.

$Interest=\frac{366.07\tiems 1.5\times 0.5}{4\times 100}\\\\Interest=\$0.686$

Hence, this investment would be worth of

$366.07+0.686\\\\=\$366.756$

The measure of an angle is 44.6°. What is the measure of its complementary angle?

Leni [432]

The measure of the complementary angle to the angle 44.6° as given in the task content is; 45.4°.

<h3>What is the measure of the complementary angle as given in the task content?</h3>

It follows from the task content that the complementary angle to angle measure 44.6° be determined.

Unlike supplementary angles which add up to 180, complementary angles add up to 90°.

Hence, the required complementary angle is; 90°-44.6° = 45.4°.
