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.

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."

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).

Answer:

119cm³

Step-by-step explanation:

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

Answer:

an ascending straight line graph is linear and has a positive slope when y is more than x or the same, when y appears less than x in slope it becomes less steeper but when all slopes are positive so are x and y relationship.

Step-by-step explanation:

You can also have a positive slope ascending straight line to a constant straight line, this becomes a change simply as and when the velocity changes.

Since the velocity vs time graph is a straight line, the secant line will always coincide with it. So, the slope of the secant line is always equal to the slope of the graph, meaning that the average acceleration is always equal to the constant acceleration. Velocity vs time graph consisting of an ascending line.
