73-(10+3)=60 you have to add 7 and 3 first, then you subtract it from 73
Answer:
Step-by-step explanation:
Actually, the complete question includes the expression of each hypothenuse, because the problem is about congruence between right triangle.
So, the hypothenuse for
is:
.
The hypothenuse for
is:
.
So, the postulate HL (Hypothenuse-Leg) states that both right triangles are equal if their hypothenuses and legs are equal. So, we have to make equal both hypothenuse expression and solve for
:

Therefore, when
these triangles are congruent.
we have the following system of equations

we know that
The intersection of both graphs is the solution of the system of equations
using a graph tool
see the attached figure
the solution is the point 
therefore
<u>the answer is</u>
the solution of the system of equations is the point 
A) In order to create a sampling plan, you need to follow the following 5 steps:
1) Define the sample population: who are the customers you want to contact?
The costumers who bought a new car on a certain year.
2) Define the size of population: how many customers are you going to contact?
Of the 30000 customers who bought a car, you want to contact 1000 customers.
3) Define the contact options: how are you going to contact the customers?
You have a list of names and addresses, therefore you can send a questionnaire via mail.
4) Form a sampling frame: what is the time or contact frame to get in touch with your customers?
You will send the questionnaires and you will wait two months for the answer.
5) Define the analysis method: is yours a qualitative or quantitative research?
In your case, you want a quantitative research and therefore a probabilistic sampling.
B) The 32.5% probability refers to customers having issues with the power doors locks among the costumers who had problems, it does not consider the customers who did not have any problem or those who had problems after the first 5000 miles.
C) In order to find the probability of a power door lock problem if there have been problems within the first 5000 miles, we need to consider the whole sample:
P = 13 / 1000
= 0.013
Therefore,
N = <span>0.013 </span>× 30000
= 390
Hence, the number of new cars sold that experienced a problem with the power door locks within the first 5000 miles will be 390.
Answer:
Answer:
Step-by-step explanation:
Given: A cubic kilometer=cubic centimeters
The volume of world’s oceans= cubic kilometers of water.
⇒ The volume of world’s oceans= cubic centimeters of water.
Volume of a bucket = 20,000 cubic centimeters of water.
The number of bucket-loads would it take to bucket out the world’s oceans
Step-by-step explanation:
hence,7/10 19 bucketloads would it take to bucket out the world’s oceans.
