1. the dow jones industrial average closing prices for the bull market 1982-1986 were examined out of the 1112 trading days in that period, the average increased on 573 days. is the dow just as likely to increase as it is to decrease on any given day? 2. arthritis is a painful, chrommc inflammation of the joints. an experiment on the side effects of pain relievers examined arthritis patients to find the proportion of patients who suffer side effects when using ibuprofen to relieve the pain. if more than 3% of users suffer side effects, the food and drug administration will put a stronger waning label on packages of ibuprofen of the 440 subjects with chronic arthritis that were given ibuprofen for pain relief, 23 subjects suffered from adverse side eftfects does the fda need to put a stronger warning label on packages of ibuprofen?

the naturalist literary movement was an extension of the realist literary movement, a movement that strove to portray life as it really was hope it

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

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
