The range of y= 2/3 sin x for pi < x < 3pi/2 is ___?

victus00 [196]

Answer:

-2/3 < y < 0

Step-by-step explanation:

y = Asin(x)

Edit*

There's a node (y=0) at pi for sine wave. At 3/2pi will be the min. So range goes from -2/3 to 0

A professor has 24 pairs of socks in his drawer. 18 pairs are black and the rest are brown. He always wears black pants. He does

lesya692 [45]

Answer:

The likelihood that the professor's socks matched his pants on both days is 0.5625

Step-by-step explanation:

Total no. of pair of socks = 24

No. of black pairs = 18

We are given that he selects one pair of socks on Monday and one on Tuesday. Since he has lots of clean socks in the drawer he does not do laundry.

So, It is a case of replacement

He always wears black pants.

We are supposed to find he likelihood that the professor's socks matched his pants on both days i.e. Black socks both days.

So ,Probability of wearing black socks on Monday = $\frac{18}{24}$

So ,Probability of wearing black socks on Tuesday = $\frac{18}{24}$

So,the likelihood that the professor's socks matched his pants on both days = $\frac{18}{24} \times \frac{18}{24}=0.5625$

Hence the likelihood that the professor's socks matched his pants on both days is 0.5625

Charlie does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at lea

german

Answer:

$(x_1,y_1) = (0,9)$

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

$(x_3,y_3) = (6,12)$

Step-by-step explanation:

Given

x = hours spent on cardiovascular work

y = hours spent on weight training

From the first statement,

Each week: he spends at least 9 hours

This is represented as:

$Total \ge 9$

$x + y \ge 9$

From the second statement,

Each week: he spends a max of 12 hours on weights

This is represented as:

$Weight \le 12$

$y \le 12$

From the third statement,

Each week: he spends a max of 6 hours on cardio works

This is represented as:

$Cardio \le 6$

$x \le 6$

So, the inequalities are:

$x + y \ge 9$

$y \le 12$

$x \le 6$

See attachment for the graph where the solution are also highlighted

From the attachment, the solutions are:

$(x_1,y_1) = (0,9)$

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

$(x_3,y_3) = (6,12)$
