Shahruk plays four games of golf. His four scores have a mean of 75, a mode of 78 and a median of 77. Work out his four scores.
Answer:
the four scores are 68, 76, 78, and 78.
Step-by-step explanation:
The mean of the four scores is 75.
So, the sum of all the four scores is equal to the product of mean and number of scores. Therefore,
Sum of scores , 'S' = Mean Number of scores.
Now, let one of the middle scores be 'x'.
Since the number of scores is even, the median is half of the sum of the two middle terms.
Median is given as 77 and mode is 78.
So, median is given as:
As 76 is smaller than 78.
So, the 2nd score is 76 and third score is 78.
Since mode is 78, it has to be repeated more than once. So, the fourth score will also be 78.
Now, let the first score be 'y'. Therefore, the sum is given as:
Therefore, the four scores are 68, 76, 78, and 78.

7. What is the radius of a circle whose area is 154 square centimeters?
Answer:
7.001 cm
Step-by-step explanation:
A = pi r^2
154 = pi r^2
r^2 = 154/pi
r = sqrt(154/pi)
r = 7.001
How many roots ( real and complex) describe the given polynomial function?
f(x)=x^3 +9x
A. three real roots
B . one real root and two complex roots
C. three complex roots
D. two real roots and one complex roots
Answer: d
Step-by-step explanation:
because after you multiply x 3 times you can use the 3 would be the square root of the number you got and a complex root you can't do that
For example: 9 x 3 = 27 the square root of 27 is 5.2 and that's is rounded
A five question multiple choice quiz has five choices for each answer. Use the random number table provided, with O's representing incorrect answers, and 1's
representing correct answers to answer the following question: What is the experimental probability of correctly guessing at random exactly one correct answer?
Answer:
You will need to count the amount of 0's and total them left to right = per question and total them top to bottom for answering a total
answering b total answering c total etc..
This creates line of 5 totals at the bottom of table and other totals per question = amount of questions x total.
The experimental probability is setting all 1/5 (1 answered question and multiplying it by the inverse of 4/5 non answered questions = 1/5 = 1/25
p) 1/5 x 1/5 = 1/25

The table shows the gallons of water in a pool over time.
A two column table with six rows. The first column, Time in minutes, has the entries, 0, 1, 2, 3, 4, 5. The second column, Water in Pool in gallons, has the entries, 50, 44, 38, 32, 26, 20.
Choose the term that describes the slope of the line of a graph representing the data in the table.
The slope of a line graphed to represent the volume of water in a pool over time would be described as
.
Answer:
6 gallons per minute
Step-by-step explanation:
Let the function that models the quantities of water, Q (in gallons) in a pool over time, t (in minutes), is
Q = a + bt ........... (1)
Now, Q(t = 0) is given to be 50 gallons.
So, a = 50 and b denotes the rate at which the quantity of water in the pool is decreasing and it is given by the slope of equation (1).
Now, two points on the graph are (0,50) and (1,44).
So, the slope = b = = - 6 gallons per minute.
Therefore, the equation of this situation is given by Q = 50 - 6t, where the slope is equal to - 6 gallons per minute. (Answer)
The slope of the line graph representing the data would be described as "negative" or "decreasing."
We have,
The slope of a line represents the rate of change between two variables.
In this case, the variables are "Time in minutes" and "Water in Pool in gallons.
" The slope of the line graph representing this data would be described as "negative" or "decreasing."
This is because as time increases (going from 0 to 5 minutes), the amount of water in the pool is decreasing (going from 50 gallons to 20 gallons).
When the slope of a line is negative, it indicates a decreasing trend or a decrease in the value of one variable as the other variable increases.
Thus,
The slope of the line graph representing the data would be described as "negative" or "decreasing."

Find the measure of the angle indicated
Answer:
137 degrees
Step-by-step explanation:
in the triangle with 60 degrees : the top angle must be also 45 degrees (the same as the angle above it).
then its third angle must be 180 - 60 - 45 = 75 degrees (because the sum of all angles is always 180 degrees in any triangle).
then the sum of this 75 degrees angle, then the neighboring 68 degree angle and the next one (the left angle in the triangle with 100 degrees) together must be again 180 degrees, because all angles around a point on one side of a line are 180 degrees (a half circle).
that means this left angle of the 100 degrees triangle is
180 - 75 - 68 = 37 degrees.
that means that the right angle of the 100 degrees triangle is
180 - 37 - 100 = 43 degrees (again, because of the sum in a triangle).
and now that gives us the ? angle as
180 - 43 = 137 degrees
because this is again the sum around s point on a line (the line is the arrow line starting at the 100 degrees angle pointing leading and pointing to the bottom right).
