D. 12
Answer:
Step-by-step explanation:
i think i would need to see a picture
Answer:
D. 12
a^2 + b^2 = c^2
so that will be 5^2 + b^2 = 13^2
so now that we have the equation we just solve it
5^2 + b^2 = 13^2
25 + b^2 = 169
b^2 = 144
b = 12
5^2 + 12^2 = 13^2
25 + 144 = 169
so the answer is A) 12

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.

For the figure below find BC to the nearest whole number CD=15
Answer:
BC = 3
Step-by-step explanation:
The length of the side BC is 3 units.
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.

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.
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

question on the picture:
Answer:
[tex]36\ feet[/tex]
Step-by-step explanation:
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]
[tex]/1.7[/tex]
[tex]x=36[/tex]
III Question 4 of 10 ( point) Question Attempt: 1 of Unlimited Susan makes house calls. For each, she is paid a base amount and makes additional money for each hour she works, The graph below shows her pay in dollars) versus the number of hours worked. Use the graph to answer the questions.
Answer:
a) $30
b) 30
Step-by-step explanation:
a) Her starting pay is $60. After an hour it goes up to $90. 90-60=30.
b) Every hour, the pay goes up 30. Slope is calculated as the change in y divided by the change in x. That means 30/1, or just 30 is the slope.

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?
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

investifgation: when one or more poeple or maybe you syourself or really anybody doing an inquiry or study or basically checking something like a detective example is crime scene investigation
observation: something you can tell using ur 5 senses - sight, smell, touch, hear, taste
evidence: information to back up a claim or something that happened
conclusion: what you can decide, conclude based on what the data u got
2. if you get wrong data, you may cconclude something very different than what something actually is.
