A university class has 29 students: 11 are nursing majors, 9 are psychology majors, and 9 are art majors. The professor is plann

babymother [125]

Answer:

0.089

Step-by-step explanation:

Since there are 9 art majors, the probability of the first student being chosen is 9 out of the 29 students total. The second student is being chosen from a sample of 28 students and 8 art majors.

9/29=.31

8/28= .286

.31 x .286=0.089

The circumferences of WNBA basketballs follow a normal distribution where mean = 29.0 ; and standard deviation = 0.1 inches.

slega [8]

Answer:

$P(X$

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

$P(z$

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

84%

Step-by-step explanation:

Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:

$X \sim N(29,0.1)$

Where $\mu=29$ and $\sigma=0.1$

We are interested on this probability

$P(X$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X$

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

$P(z$

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

84%

3. Given that P||S and r||q and that <2 = 120 degrees, find m<6.

Nikitich [7]

Answer:

B. 60 degrees

Step-by-step explanation:

∠6 corresponds to ∠3, which is supplementary to ∠2.

∠6 = 180° -∠2 = 180° -120°

∠6 = 60°
