4( c + $1.50 )

The question tells you that the total price for FOUR people is $21, and then ask about the cost PER PERSON, meaning that you need to figure out the cost of a singular person.
The question tells you that each person pays $1.50 and they also need to pay for a game, which they have given the value to be c.
So the you add those two cost together ($1.50 + c) and then multiple it by 4 as the question originally tells you that there are 4 players.

Find the maximum rate of change of f at the given point and the direction in which it occurs. f(x, y) = 9 sin(xy), (0, 8)

malfutka [58]

Answer:

The magnitude is $\Delta f(0,8) = 72$

The direction is $i$ i.e toward the x-axis

Step-by-step explanation:

From the question we are told that

The function is $f(x, y) = 9sin(xy) \ \ \$

The point considered is $(0,8 )$

Generally the maximum rate of change of f at the given point and the direction is mathematically represented as

$\Delta f(x,y) = [\frac{\delta f(x,y)}{\delta x } i + \frac{\delta f(x,y)}{\delta y } j ]$

$\Delta f(x,y) = [\frac{\delta (9sin(xy))}{\delta x} i + \frac{\delta (9sin(xy))}{\delta y} i ]$

$\Delta f(x,y) = [9y cos (x,y) i + 9xcos (x,y) j]$

At $(0,8 )$

$\Delta f (0,8) = [9(8) cos(0* 8)i + 9(8) sin(0* 8)j ]$

$\Delta f (0,8) = 72 i$

A couple has six children what is the probability that they have all boys

Step2247 [10]

For any birth we have only two possible outcomes either boy or girl. So the chance of getting boy or girl on birth same which is 1/2.

The probability of getting baby boy or baby girl on any birth is

P(Boy) = P(Girl) = 0.5

If a couple has six children then probability that all are boys is

P( all six are boy) = (0.5)^6

= 0.015

The probability that all six are boy is 0.015
