Find x A. 212√2 B. 212–√ C. 213√2 D. 7
Answers
The value of x in the triangle is (d) 7
How to solve for x?The complete question is in the attached image.
From the attached image of the triangle, we can see that the triangle is a right triangle, and x can be solved using the following sine function
[tex]\sin(45) = \frac{x}{7\sqrt 2}[/tex]
Evaluate sin(45)
[tex]\frac 1{\sqrt 2} = \frac{x}{7\sqrt 2}[/tex]
Solve for x
[tex]x = \frac{7\sqrt 2}{\sqrt 2}[/tex]
Divide
x = 7
Hence, the value of x in the triangle is (d) 7

Baby rabbits were sorted into three groups, based upon which food they preferred when given a choice: Brand A rabbit food, Brand B rabbit food, or a diet of raw vegetables. For two months each group was restricted to their preferred diet (they were no longer given a choice in diet). Measurements for the height, weight, and length of the rabbits was taken each week for two months. The rabbits in the group with the diet of raw vegetables had significantly more growth that the other two groups. What conclusion can be drawn from this study?
Answers
Answer: That raw vegetables are better for the rabbit's growth than rabbit food.
Answer:
The rabbit food that was strictly a diet of raw vegetables is healthier for the rabbits.

Given: p: x is prime. q: x is even. What is the truth value of p^q when x is replaced by 2?
Answers
Truth Value for p^ q when x is replaced by 2 is also true. ( p^q is True)
What is a prime number?The prime numbers are those numbers that have only one factor namely 1 and the number itself.
Given that p = x is prime and q = x is even. If we replace x by 2 then we would get
p = 2 is prime
q = 2 is even
p^q will be held true only if p and q both are true.
The statement for p and q both are true because 2 only has two factors only 1 and 2 themselves.
2 is also considered an even number (2,4,6,8,...)
Since p = true and q = true then
p and q = p^q = true
Thus, p^q is True.

The continuous version of the logistic model is described by the differential equation is:
(dN)/(dt)=(rN(K-N))/K. (where r is the Malthusian parameter (rate of maximum population growth) and K is the so-called carrying capacity (i.e., the maximum sustainable population).

[tex]\rightarrow \sf - 3y = 12 - 4x[/tex]

Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven linear equation:
[tex]4x-3y=12[/tex]
Find the slope of the given linear equation by rewriting the equation so that it is in slope-intercept form (i.e. make y the subject):
[tex]\implies 4x-3y=12[/tex]
[tex]\implies 4x-3y+3y=12+3y[/tex]
[tex]\implies 4x=12+3y[/tex]
[tex]\implies 4x-12=12+3y-12[/tex]
[tex]\implies 4x-12=3y[/tex]
[tex]\implies \dfrac{3y}{3}=\dfrac{4}{3}x-\dfrac{12}{3}[/tex]
[tex]\implies y=\dfrac{4}{3}x-4[/tex]
Therefore, the slope of the given line is 4/3.
If two lines are perpendicular to each other, the product of their slopes will be -1. Therefore, the slope (m) of the line perpendicular to the given line is:
[tex]\implies m \times \dfrac{4}{3}=-1[/tex]

By using unit conversion and direct proportionality model, we find that 45 bushels of soybeans are equal to a weight of 1.225 tonnes.
How many tonnes are a given quantity of bushels?
In this question we have an application of direct proportionality model, whose form is shown below:
y = k · x (1)
Where:
x - Quantity of bushelsk - Conversion rate, in tonnes per bushel.y - Quantity of tonnesIf we know that x = 45 bu and k = 1/36.744, then the soybean quantity in tonnes is:
y = (1/36.744 t/bu) · (45 bu)
y = 1.225 t

Answers
According to the information, it can be inferred that the answer is No, because informing the students that there will be a $10 increase... (option B).
Why is this question invalid?This question is not valid because it specifies information that would surely change the answer of the respondent.
The information that the question reveals is that there is going to be a raise, this will cause a refusal in people to accept that raise just to see a live band.
According to the above, the question is invalid because it reveals information that will modify the answer of those who respond.
Note: This question is incomplete because the options are missing. Here are the options:
A. No, because questions about musical preferences are always invalid because you cannot measure people's opinions on subjective manners like music and other creative arts.
B. No, because informing the students that there will be a $10 increase in the cost of a prom ticket may make them more likely to say that they would not like a live band to perform.
C. No, because students should be given a sample of the band's music to allow them to offer a more informed opinion.
