Express each rate as a unit rate. (5points each)

1 answer:

5 0

To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.

For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.

Likewise for the other question it would be 270/15.

A new surgical procedure is said to be successful 60% of the time. Suppose the operation is performed five times and the results

USPshnik [31]

Answer:

0.07776, 0.3456,0.08704

Step-by-step explanation:

Given that a new surgical procedure is said to be successful 60% of the time

Let X be the no of successes

Then X has only two outcomes and each trial is independent of the other

Hence X is binomial with p = prob of success in a single trial = 0.60

n = Number of operations performed = 5

Prob that

a) all five operations are successful =

$P(X=5)\\= (0.6)^5\\=0.07776$

(b) exactly three are successful

= $P(X=3) = 5C3 (0.6)^3(0.4)^2\\= 0.3456$

$==P(X$

The future value of an investment, P after n years at an APR of r% compounded t times a year is given by
$FV=P\left(1+ \frac{r}{t} \right)^{nt}$

Given <span>an investment of $2300, after 7 months, earning 6.6% APR, compounded monthly, the future value is given by
$FV=2,300\left(1+ \frac{0.066}{12} \right)^{12\left( \frac{7}{12}\right) } \\ \\ =2,300(1+0.0055)^7=2,300(1.0055)^7 \\ \\ =2,300\times1.03914=\$2,390.02$ </span>

Sergio039 [100]

Answer:

200 minutes, cost $44.00

Step-by-step explanation:

x = minutes

14 + .15x = 22 + .11x

.04x = 8

x = 200 minutes

14 + (.15*200)

14 + 30 = 44

22 + (.11*200)

22 + 22 = 44
