There are 25 dogs playing in the dog park. you are a "dog" person and wonder which dog will be the first to come up to you when you enter the park. there are 15 golden retrievers, 5 pugs, 4 pomeranians, and 1 terrier. what is the probability that the first dog to come over to you will be a pug?

i chose 5/25

2. one psyc 317 class has 10 people in it; another has 50 people in it. the average grade in the 10-person class is 72% (high probability of getting a c); the average grade in the 50-person class is 85% (high probability of getting a b). which class average is the most reliable?

a. the 10 person class

b. 50 person class

c. cannot determine with this information

d. both equally

i chose the 50 person class.

brainliest

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
