Answer:

Step-by-step explanation:

The median is the middle score of a distribution. To calculate the median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Consider this set of numbers: 1, 3, 3, 6, 7, 8, 9. Since you have an odd number of scores, the median (middle number) would be 6.

What happens when you have an even number of scores so there is no single middle score? Consider this set of numbers: 1, 2, 2, 4, 5, 7. Since there is an even number of scores, you need to take the average of the middle two scores, calculating their mean

in this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3. So, for this example, the median is 3.

If Free Yer Assets Bank (FYAB) will give you 0.25% compounded quarterly and I.M.A.Q.T.π bank will give you 0.23% interest compou

ivann1987 [24]

Answer:

FYAB gives a better deal.

Step-by-step explanation:

Compound interest:

$A = P(1 + \dfrac{r}{n})^{nt}$

Continuously compounded interest:

$A = Pe^{rt}$

For the quarterly compounded interest, r = 0.25%, and n = 4.

$2P = P(1 + \dfrac{0.0025}{4})^{4t}$

$1.000625^{4t} = 2$

$\log (1.000625^{4t}) = \log 2$

$4t(\log 1.000625) = \log 2$

$t = \dfrac{\log 2}{4\log 1.000625}$

$t = 277$

For the continuously compounded interest, r =0.23%

$A = Pe^{rt}$

$2P = Pe^{0.0023t}$

$2 = e^{0.0023t}$

$\ln 2 = \ln e^{0.0023t}$

$\ln 2 = 0.0023t$

$t = \dfrac {\ln 2}{0.0023}$

$t = 301$

The quarterly compounded doubles in 277 years.

The continuously compounded doubles in 301 years.

Two joggers run 8 miles north and 5 miles west. What is the shortest distance, to the nearest tenth of a mile, they must travel

BartSMP [9]

Answer:

The shortest distance to return starting point = 9.4 miles.

Step-by-step explanation:

Applying pythagoras theoram

The shortest distance = $\sqrt{8^{2} + 5^{2} }$ = 9.43

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,

Ulleksa [173]

Answer:

Step-by-step explanation:

Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.

This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

Find sec Θ if the terminal side of Θ in standard position contains the point (4, -3)

CaHeK987 [17]

If we plot that point we find ourselves in QIV. The distance along the x axis is 4, and the distance down from that point is -3. If we create a right triangle with that segment, that segment serves as the hypotenuse of the triangle. We need its measure. Using Pythagorean's theorem, $4^2+-3^2=c^2$ and $16+9=c^2$ . We see that c = 5. We need now to find the secant of that right triangle. Secant if the co-identity of cosine which is side adjacent over hypotenuse. That means that secant is the hypotenuse over the side adjacent. So our secant theta = 5/4
