Answer:

10) x=90

9) x=20

Step-by-step explanation:

x+2x=180

3x=180

divide 180 by 3x=90

straight lines add up to 180 degrees.

9) x+8x=180

9x=180, thus 20.

A play has tickets available for 8 orchestra seats and 12 balcony seats. The next person to buy a ticket will be randomly assign

qaws [65]

The probability that the next person will be assigned an orchestra seats is 2/5.

<h3>What is Probability?</h3>

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Available Orchestra seats = 8

Balcony seats = 12

Total available seats = 12 + 8 = 20

Probability = Favorable Outcome / Total Outcome

Probability of getting orchestra ticket = 8/20

= 2/5

Thus, the probability that the next person will be assigned an orchestra seats is 2/5.

The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent

Ipatiy [6.2K]

Answer:

y = 16.3216X - 330.3904

322 pounds;

Result is significant

Step-by-step explanation:

Given the data:

Chest size, x : 41,54,44,55,39,51

Weight, Y : 328,528,418,580,296,503

Using technology, the prediction model obtained by fitting the data is :

y = 16.3216X - 330.3904

Where, x = chest size ; y = weight

The best predicted weight of a bear with chest size of 40 is

Put x = 40 in the equation :

y = 16.3216(40) - 330.3904

Y = 322.4736

Y = 322 pounds

At α = 0.05

The regression Coefficient, R value obtained is 0.986 ; using this to obtain the Pvalue ;

df = n - 1

Pvalue(0.986, 5) = 0.00198

Since, Pvalue < α ; result is significant at α = 0.05
