Answer:
Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.
Step-by-step explanation:
From the question:
100, 70, 85 on three of her five tests
Total number of test = 5
mean of the five scores is 75
mean = average of the five scores
Average score = Total score / total number of test
Total score = Average score * total number of test
= 75*5 =375
to find remaining two tests' scores
Total score - the 3 scores from question
= 375 - 100 - 70 - 85
=120
If u want to find the score of each of the unknown test
From question:
She could not remember the other two scores, which were the same.
Thus,
The score of one test
= 120/ 2
=60

2n = 88
2n/2 = 88/2

marbles are there altogether?
A. 25
B. 40
C. 55
D. 120
Answers
Answer:
D) 120
Step-by-step explanation:
if there are 40 blue marbles and the ratio of blue is 8, then the multiplier is 5
# of red marbles: 11 x 5 = 55
# of pink marbles: 5 x 5 = 25
55 + 40 + 25 = 120

What is the value of k?
Answers
Answer:
[tex]( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12[/tex]
Answer:
Step-by-step explanation:
a² + 2ab + b² = (a + b)²
2ab = 2 * x * 8 = 16x
x² + 16x + 64 = x² + 2* x * 8 + 8²
= (x + 8)²
x² + 16x + 8 - (x +8)(x - 4) = (x+8)² - (x+ 8) (x -4)
= (x +8)(x +8) - (x + 8)(x - 4)
(x +8 ) is common in both terms
= (x + 8) [ (x + 8) - (x - 4) ]
= (x + 8) [ x + 8 - x + 4 ]
{Combine like terms. so x + (-x ) = 0 and 8 +4 = 12}
= (x + 8) [ 12]
k = 12

For the past ten years, Michelle has been tracking the average annual rainfall in Boynton Beach, Florida by recording her data in the given table. She has concluded that the relationship can be modeled by a linear function.
Year 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013
Average Rainfall(in inches) 62.33 61.8 61.27 60.74 60.21 59.68 59.15 58.62 58.09 57.56
Use the values provided in the table to create a linear graph of the data. On the graph, let x = 0 represent the year 2004. Be sure to include all proper labels on the graph.
Answers
55.44 inches
Step-By-Step Explanation
part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.
slope = m = (change in rainfall)/(change in years)
= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53
then the point-slope form of the equation of the line can be written as
y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)
y = -0.53x +62.33 . . . x = years after 2004
part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is
y = -0.53·13 +62.33 = 55.44 . . inches
the predicted rainfall in 2017 is 55.44 inches.
The linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]
What are linear functions?A linear function is a graph that has a constant rate.
From the table, we have the following ordered pairs
(x,y) = (0,62.33) and (1, 61.8)
Start by calculating the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2-x_1}[/tex]
So, we have:
[tex]m = \frac{61.8 -62.33}{1-0}[/tex]
[tex]m = -0.53[/tex]
The linear equation is then calculated as:
[tex]y = m(x -x_1) + y_1[/tex]
So, we have:
[tex]y = -0.53(x -0) + 62.33[/tex]
Expand
[tex]y = -0.53x + 62.33[/tex]
Hence, the linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]
