Answer:
58.1 degrees
Step-by-step explanation:
Given the following
JK = 9.4miles (towards south) negative y axis
If the move 15.1 miles towards east (that will be towards the positive x axis)
Using the SOH CAH TOA identity
opposite= 15.1 miles(side facing m<J)
adjacent= JK = 9.4miles
tan theta = opposite/adjacent
tan m<J = 15.1/9.4
tan m<J = 1.6063
m<J = arctan (1.6063)
m<J = 58.09 degrees
Hence the measure of m<J to the nearest tenth is 58.1 degrees
Answer:
30 65/72 yards
Step-by-step explanation:
First, change the first fraction to a mixed number. 8 x 7 = 56, plus 7 equals 63. So, the first fraction is 63/8. Next, 9 x 5 equals 45, plus 7 equals 52. So, the second fraction is 52/9. Now, you can't add fractions with different denominators, so you have to change the denominators. You can multiply the first fraction by 9 and the second fraction by 8 so they will have the same denominator of 72. 63/8 x 9 equals 567/72. 52/9 x 8 equals 416/72. 567 + 416 = 983. So, the sum of the first two fractions is 983/72. Now, convert the last fraction into a mixed number. 17 x 4 = 68, plus 1 equals 69. So, the last fraction is 69/4. Once again, the numbers need to have the same denominator, so we can multiply 69/4 by 18 to get 1242/72. Now, 983 + 1242 = 2225, so the sum of all of the fractions is 2225/72. Because this fractions is HUGE, we can change this into a mixed number. 2225/72 as a mixed number is 30 65/72. Because this fraction can't be simplified anymore, the answer would be 30 65/72. Hope this helped!
Answer:
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.
For example, John a psychologist standing on the street requesting that passersby join in his research study.
