Answer:
x = -7
Step-by-step explanation:
Firstly, under the rule of opposite vertical angles, you know that any angles opposite of each other in a cross section have the same degree measure.
Therefore the last remaining angle in the triangle will be 85 degrees, since it is vertically opposite of the 85 degree angle.
Next, you know that all three angles of a triangle MUST equal 180 degrees to be considered a complete triangle.
Therefore, use the equation below to solve for x:
180 = 54 + 85 + (48 + x)
x = 180 - 54 - 85 -48 = -7
Compare the scores: a score of 75 on a test with a mean of 65 and a standard deviation of 8 and a score of 75 on a test with a mean of 70 and a standard deviation of 4.
Answer:
The Zscore for both test is the same
Step-by-step explanation:
Given that :
TEST 1:
score (x) = 75
Mean (m) = 65
Standard deviation (s) = 8
TEST 2:
score (x) = 75
Mean (m) = 70
Standard deviation (s) = 4
USING the relation to obtain the standardized score :
Zscore = (x - m) / s
TEST 1:
Zscore = (75 - 65) / 8
Zscore = 10/8
Zscore = 1.25
TEST 2:
Zscore = (75 - 70) / 4
Zscore = 5/4
Zscore = 1.25
The standardized score for both test is the same.

The expression below is the factorization of what trinomial-1(x+5)(x+6)
Answer:
-x^2 - 11x -30
Step-by-step explanation:
Solve using foiling. Ignore the -1 to begin with and just look at the part in parenthesis. Do x from the first parenthesis times the stuff in the second parenthesis.
ie: x(x) and x(6)
ie: x^2 + 6x
Then do the 5 times the things in the second parenthesis.
ie: 5(x) and 5(6)
ie: 5x + 30
Then add what you got from multiplying the first value to what you got from multiplying the second.
ie: x^2 + 11x + 30
This is a trinomial because it has three different variables. Now change all the signs to negative because of the -1 out front.
ie: -x^2 - 11x -30

What's the ratio equivalent to 15 to 60.
Answer:
1:4
Step-by-step explanation:you can simplify the ratio by finding the LCM on both sides and dividing the number by the lcm in which this case is 15.
15/15=1
60/15=4
so 1:4
The answer to the question is 1:4
Step-by-Step explanation:
We have to divide each number over here by the LCF of 15.
The LCF (Least Common Factor) of 15 is 5.
Given the LCF of 15 is 15, we will divide both given numbers by 15.
[tex]\text {60 / 15 = 4 and 15 / 15 = 1}[/tex]
We will put the numbers back in order from least to greatest.
The ratio we find is 1:4, and the answer to your question is 1:4.

Step-by-step explanation:
we kno that a triangle is 180 degrees so we just add the first two angles
37 + 82 = 119
then subtract that from 180
180 - 119 = 61
so x = 61 degrees

events. Which number sentence shows the best way to
estimate Mauricio's score for each event?
(a) 35 = 5 = 7
(b) 35 - 7 = 5
(C) 30 = 10 = 3
(d) 40 = 10 = 4
Answer choice:
Explain how you chose your answer.
Answer:
Mauricio's score for each event is 7.
Step-by-step explanation:
Mauricio scored a total of 34.42 points in five gymnastic events.
We can round off his score as 35.
To find Mauricio's score for each event, divide total score and no of events as follows :
[tex]n=\dfrac{35}{5}\\\\=7[/tex]
Hence, Mauricio's score for each event is 7.

If he used 16 lb. of flour making bread and begin mathsize 14px style 2 over 3 end style lb. for each batch of muffins, how many batches of muffins did he make?
Represent the division expression using unit form.
Answer:
I think the question you are trying to say is . . . A baker bought some flower. He used 2/5 of the flour to make bread and used the rest to make batches of muffins. If he used 16lb of flour making bread and 2/3 lb for each batch of muffins, how many batches of muffins did he make?
So I have provided the answer and explanation below.
Step-by-step explanation:
He make 36 batches of muffins.
Consider the provided information.
It is given that he used 2/5 of the flour for bread, and he used 16lbs for bread.
Let total amount of flour is x lbs, now convert above statement into mathematical form.
2/5 x = 16
2x/5 = 16
x = 5 • 16/2 = 80/2
x = 40
Therefore, he bought 40 lbs of flour.
He used 16 lb out of 40.
So for muffins he left with 40-16=24 lbs of flour.
It is given that he used 2/3 lb. For each batch of muffins.
Divide 24 with 2/3 lb.
24/2/3 = 24 • 3/2
72/2 = 36
Hence, he make 36 batches of muffins.

Mathematically:
3 to 6 and 4 to x
Represent as a ratio:

in how many ways 5 passengers can sit in a compartment having 16 vacant seats
9514 1404 393
Answer:
524,160
Step-by-step explanation:
Assuming order matters, it is the number of permutations of 16 things taken 5 at a time:
16P5 = 16!/(16-5)! = 16·15·14·13·12 = 524,160
_____
The first passenger can pick any of 16 seats; the second can pick any of 15 remaining seats; and so on until all 5 passengers have chosen a seat. The number of possible different arrangements is the number shown above.
