Answer:
x= 7/3
Step-by-step explanation:
y=2x+5
5x-2=2x+5
transfer 2x to the left side and -2 to the right side you get
5x-2x=2+5
as it transfers the sign changes
3x=7
x=7/3

Two quantities of data have a strong positive correlation. Can the line of best fit for the data set have a correlation coefficient of 0.25? Explain.
Choose the correct answer below.
O A. Yes. The sign of the correlation coefficient indicates the type of correlation data have. Because 0.25 is positive, it is possible for data with a strong
positive correlation to have it as the correlation coefficient
OB. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to 1 than 0.25 is
OC. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to - 1 than 0.25
OD. No. By definition, data that have a strong positive correlation have a strong linear relationship. The correlation coefficient would be closer to than 0.25 is.
O E. Yes. By definition, data that have a strong positive correlation have a strong linear relationship. A correlation coefficient of 0.25 indicates a fairly strong
is.

A student's course grade is based on one midterm that counts as % of his final grade, one class project that counts as % of his final grade, a set of homework assignments that counts as % of his final grade, and a final exam that counts as % of his final grade. His midterm score is , his project score is , his homework score is , and his final exam score is . What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.
Answers
Answer:
The overall score is 75.6
Letter grade is C
Step-by-step explanation:
The question has missing details (See comment section for complete question).
From the complete question, we have:
Proportion:
[tex]Midterm = 15\%[/tex]
[tex]Project = 25\%[/tex]
[tex]Assignment = 40\%[/tex]
[tex]Exam = 20\%[/tex]
Scores
[tex]Midterm = 66[/tex]
[tex]Project = 90[/tex]
[tex]Assignment = 75[/tex]
[tex]Exam = 66[/tex]
Solving (a): The overall score
To do this, we simply calculate the mean of the given data.
The mean is calculated by multiplying each proportion by the scores..
So, we have:
[tex]Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66[/tex]
[tex]Overall = 9.9 + 22.5 + 30 + 13.2[/tex]
[tex]Overall = 75.6[/tex]
Solving (b): The letter grade
From the question, we have:
[tex]A: Mean \ge 90[/tex]
[tex]B: 80 \le Mean < 90[/tex]
[tex]C: 70 \le Mean < 80[/tex]
The overall score falls in the following category:
[tex]C: 70 \le Mean < 80[/tex]
Because:
[tex]70 \le 75.6 < 80[/tex]
Hence, the letter grade is C

What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The right triangle is shown in the figure.
Let the distance BC be x and
The side AB be y.
According to trigonometric ratios,
[tex]tan \theta=\frac{opposite}{adjacent}[/tex]
Consider Δ ABD,
⇒ [tex]tan (20) = \frac{y}{x+15}[/tex]
⇒ [tex]0.3639=\frac{y}{x+15}[/tex]
⇒ [tex]y=0.3639(x+15)[/tex] -------- (1)
Now consider Δ ABC,
⇒ [tex]tan(65)=\frac{y}{x}[/tex]
⇒ [tex]2.144=\frac{y}{x}[/tex]
⇒ [tex]y=2.144x[/tex] --------- (2)
From equation 1 and 2,
⇒ [tex]2.144x=0.3639(x+15)[/tex]
⇒ [tex]2.144x=0.3639x+5.4585[/tex]
⇒ [tex]1.7801x=5.4585[/tex]
⇒ [tex]x=\frac{5.4585}{1.7801}[/tex]
⇒ [tex]x=3.06[/tex] ≈ [tex]3[/tex]
Hence we can conclude that the length of the side BC is 3 units.

Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,
[tex](height):(shadow)[/tex]
As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,
[tex]6:1.7[/tex]
It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).
[tex]6:1.7=x:10.2[/tex]
Cross products,
[tex](1.7)(x)=(6)(10.2)[/tex]
Simplify,
[tex]1.7x=61.2[/tex]
Inverse operations,
[tex]1.7x=61.2[/tex]

5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 144
b = 12
5^2 + 12^2 = 13^2
25 + 144 = 169

Answers
Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
