Answer: The picture's dimensions will be 10"x15".
Step-by-step explanation:
Length: 4 2 10
Width: 6 3 15
You can tell because 15 isn't divisible by 6, but it is divisible by 3, which goes into 6.
Divide 6 by 2.
6/2=3
To keep the ratio, we must also divide 4 by 2.
4/2=2
Then, multiply 3 by 5 for the width.
3*5=15
You must also multiply 2 by 5 to get the length.
2*5=10
The picture's dimensions will be 10"x15".
You have 85.5×6 that will equal 513

Answer:
Now we can find the p value with the following probability:
Step-by-step explanation:
Information given
n=97 represent the random sample taken
estimated proportion of defective
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to tests
We want to tet if the true proportion is less than 6%, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can find the p value with the following probability:
