Wxy is a right triangle.
Answer:
B. False
Step-by-step explanation:
To check if its a right angle triangle, you need to check if pythagoras' theorem works:
a² + b² = c²
(√17)² × (√17)² = 289 which is not equal to (√34)²
Use the graph above to demonstrate your understanding of slope and density.
a. Calculate the slope of the trend line using this mathematical equation: Slope = Y2-Y1 / X2-X1
(Use the 2 yellow dots on the graph and show your work)
b. In this graph (mass vs volume), what does the slope represent?

Determine whether the triangles are similar
Step-by-step explanation:
ur are choosing correct option as,
W = Y ( 90° given )
VW = YZ ( as both are || to eachother so their length is same )
angle X = X ( vertically opposite angle)
therefore, ∆WVX = ∆ZYX are congruent according to SAS congruency rule/criteria.
hope this answer helps you dear..take care and may u have a great day ahead and also ur exam/test goes well!.

Ruben, Shelly, and Malcolm have recorded a hit song. Ruben gets 2/5 of the income, Shelly gets 1/3, and Malcolm gets the rest. If they earn $300,000, how much does Malcolm earn?
Answer:
$ 80,000
Step-by-step explanation:
2/5 + 1/3 = (6 + 5)/15 = 11/15
15/15 - 11/15 = 4/15
4/15 of 300,000
4/15 x 300,000 = 1,200,000/15 = 80,000

Which table represents a linear function?
Answer:
Table 1 (leftmost)
Step-by-step explanation:
A linear function has a common difference between all of the x-values. This means that all the x-values change by the same amount relative to the change in y. In this case, the x-value increases by 1/2 every time that y increases by 1. The other tables do not work because their change is inconsistent. There is no number being added each time. Therefore, they are not linear. If you were to graph these tables, only table 1 would make a straight line.

Brainlisted for right answer!!! 25 points!!! Please help me!!! I really need this done!!!
Answer:
Step-by-step explanation:
While I can not give you the exact answer as it is a graph, it's worth noting that the function is in f(x) = mx + b form.
This means the first point with an x coordinate of 0 will start at 6, and for each increase in one on the x-axis, we add 2.4.
So, the first coordinate is (0,6), the next is (1,8.4), and so on until you reach the end. That shouldn't take very long provided you can compute addition mentally.
Hope this helps and Good Luck
A math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Answer is 1/10
Answer:1/10
Step-by-step explanation:so easy
The probability that the students she selects are both boys is 1/10.
What is a probability? Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates complete certainty.Given is that a math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition.
The probability that the students she selects are both boys -
P{E} = P{1} x P{2}
P{1} : randomly selecting a seventh grader as a boy.
P{2} : randomly selecting a eight grader as a boy.
We can write -
P{1} = n{f}/n{s} = 1/5
P{2} = n{f}/n{s} = 5/10 = 1/2
P{E} = P{1} x P{2}
P{E} = 1/5 x 1/2
P{E} = 1/10
Therefore, the probability that the students she selects are both boys is 1/10.

Write the equation of a square root function that has the following graph.
9514 1404 393
Answer:
g(x) = √(x -5) +7
Step-by-step explanation:
To translate the graph of f(x) by h units horizontally and k units vertically, the function is transformed to ...
g(x) = f(x -h) +k
To translate f(x) = √x by 5 units horizontally and 7 units vertically, the function is transformed to ...
g(x) = √(x -5) +7

An insurer knows that the proportion of smokers in a population is 0.3. Furthermore, it is known that: 40% of applicants who are smokers say they do not smoke on their applications. None of the non-smoking applicants are lying on their application.
Calculate what is the probability that one of the applicants says that he does not smoke, and that in fact do not smoke.
===================================================
Explanation:
Let's say this population had 1000 people. You can pick any number you want, but I'm going for some nice big round number to work with.
The proportion of smokers is 0.3, which means 0.3*1000 = 300 people in this population are smokers and 1000-300 = 700 are nonsmokers.
Of the 300 people who do smoke, 40% of them lie on the application. This means 0.40*300 = 120 people lied. These 120 people say they don't smoke, but in fact they do smoke.
So if we were to survey this population, then 700+120 = 820 people would say they don't smoke
Only considering the people who write "don't smoke" on the survey, which is that 820 figure, 700 of them are true nonsmokers. Therefore, the probability we want is 700/820 = 0.8537 approximately

Answer:
3x²+4x-14=0
Step-by-step explanation:
Standard form of a quadratic equation is ax²+bx+c=0. To do that, simply move -3x² over to the other side by adding it. That leaves you with the answer.
