Answer:

106°

Step-by-step explanation:

AOD = COB (because of vertical angles)

COB = COF + FOB

COF = 90

FOB = 16

COB = 90 + 16 = 106

AOD = 106

Hope this helps :)

Have a nice day!

I need this answered, please and thanks
Nady [450]

Answer:

P = \frac{28\sqrt{2} }{2} units

A = 24.5 unit^{2}

Step-by-step explanation:

Length of one side

sin 45^{o} = \frac{x}{7}

7sin 45^{o}= x

7(\frac{\sqrt{2} }{2})= x

\frac{7\sqrt{2} }{2} = x

Perimeter = 4(\frac{7\sqrt{2} }{2}) = \frac{28\sqrt{2} }{2}

Area = (\frac{7\sqrt{2} }{2})(\frac{7\sqrt{2} }{2}) = \frac{98}{4} =24.5

What is opportunity sampling
Yakvenalex [24]

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.

Answer:

72

Step-by-step explanation:

principal (P)=1800

time(T)=2yrs

rate(R)=2%

SI=?

now,

SI=PTR÷100

= 1800×2×2÷100

=7200÷100

=72

so interest is 72.

hope this will help you :D
