If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select i

posledela

Answer:

$P = \frac{3}{4}$

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes. Mathematically, this is

$P = \frac{D}{T}$

In this problem, we have that:

Desired outcomes:

There are 52 cards, of which 13 are diamonds.

We want non diamond cards, so $D = 52-13 = 39$

Total outcomes:

Deck of 52 cards, so $T = 52$

Probability

$P = \frac{D}{T} = \frac{39}{52} = \frac{3*13}{4*13} = \frac{3}{4}$

Given segment AB with points (-4, 8) and (6, 3) respectively. Find the coordinates of point P that partitions Segment AB in the

netineya [11]

Answer:

$P = (2,5)$

Step-by-step explanation:

Given

$A(-4,8)$

$B(6,3)$

$m:n = 3 : 2$

Required

Determine P

Since P divides the segment into 3:2, P is calculated using

$P = (\frac{nx_1 +m x_2}{m+n},\frac{ny_1 + my_2}{m+n})$

Where

$(x_1,y_1) = (-4,8)$

$(x_2,y_2) = (6,3)$

$m:n = 3 : 2$

Substitute these values in the above formula:

$P = (\frac{2 * -4 +3 * 6}{3 + 2},\frac{2 * 8 + 3 * 3}{3 + 2})$

$P = (\frac{-8 +18}{3 + 2},\frac{16 + 9}{3 + 2})$

$P = (\frac{10}{5},\frac{25}{5})$

$P = (2,5)$

Brody deposited 8,001 in a savings account with simple interest. Four months later the account held 8,267.70. What is the intere

Travka [436]

Answer:

R = 0.8333%/month

(R = 9.9996%/year)

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving your equation:

r = (1/4)((8267.7/8001) - 1) = 0.00833333

r = 0.00833333

Converting r decimal to R a percentage

R = 0.00833333 * 100 = 0.8333%/month

Calculating the annual rate

0.8333%/month × 12 months/year = 9.9996%/year.

The interest rate required to get a total amount, principal plus interest, of $8,267.70 from simple interest on a principal of $8,001.00 over 0.333333 years (4 months) is 0.8333% per month.
