Answer:
The complete question is
Find the percent of change. Round to the nearest tenth if necessary.
Notice that this change is an increase, to fint the percetange of change, we just need to divide and then multiply by 100 to have it in percetange expression:
So, the percentage of change is 100%, because the change is 25, that was the increase.
Which means 75 invitations represents 60% of the old number of invitations.
So, the percentage of change is 40%, because that's the percentage of the difference.
You can do another process, first find the difference:
Then, you divide:
So, the percentage of change is 12.5%.
So, the percentage of change is around 43%.
Prove: PQR congruent to SRQ
Answer:
ΔPQR is congruent to ΔSRQ b the Side-Angle-Side rule of congruency
Step-by-step explanation:
The two column proof is given as follows;
Statement Reason
1. ≅ Given
2. ∠PQR ≅ ∠SRQ Given
3. ≅ By reflexive property
4. ΔPQR ≅ ΔSRQ By SAS rule of congruency
When two sides and an included angle of one triangle are congruent to the corresponding two side and an included angle of another triangle, both triangles are said to be congruent by the Side-Angle-Side SAS rule of congruency.
Answer: The size of the sample is 840.
The probability that the first three letters of the four-letter code are vowels is
Step-by-step explanation:
Th total number of letters given to form code of 4 letters = 7
Since, the order of the letters in the code matters, which means there is no repetition.
The total number of ways to form the code size =
Therefore, The size of the sample is 840.
Since, there are 3 vowels and rest of 4 letters are consonant.
The number of ways to form code such that the first three letters of the four-letter code are vowels =
The probability that the first three letters of the four-letter code are vowels is
=
The probability that the first three letters of the four-letter code are vowels is 1/35 and the size of the sample is 840.
Step 1 - Determine the sample size.
It is to be noted that the total number of letters given to form code of 4 letters = 7
Given that the order of the letters in the code matters, which means there is no repetition; hence,
The total number of ways to form the code size = 7 x 6 x 5 x 4 = 840
Thus, the size of the sample is 840.
Step 2 - Solve for the Probability
Given that there are 3 vowels and rest of 4 letters are consonant.
The number of ways to form code such that the first three letters of the four-letter code are vowels
= 3 x 2 x 1 x 4
= 24
Hence, the probability that the first three letters of the four-letter code are vowels is
= 24/840
= 1/35
