Answer:
1.67 pounds
Step-by-step explanation:
The problem above can be solved by using "direct proportion." This proportion shows that as one quantity increases, the other quantity increases and vice-versa.
Step 1: Represent the weight of the person on the moon by n.
Step 2: Set up a proportion.
[tex]\frac{105}{175}[/tex] = [tex]\frac{1}{n}[/tex]
Step 3: Cross multiply.
105 x n = 175 x 1
105n = 175
Step 4: Find n by dividing both sides by 105.
n = [tex]\frac{175}{105}[/tex]
n = 1.666 or 1.67 pounds (lowest term)
A pound of person on Earth will weigh 1.67 pounds on the moon.

Step-by-step explanation:
There are 2 1/3 inches in 1 2/5 groups of 1 2/3 inches.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
There are 1 2/5 groups of 1 2/3 inches.
Now,
Since, There are 1 2/5 groups of 1 2/3 inches.
Hence, The number of inches = 1 2/5 × 1 2/3
= 7/5 × 5/3
= 7/3 inches.
Thus, There are 2 1/3 inches in 1 2/5 groups of 1 2/3 inches.

The table below represents a linear function f(x) and the equation represents a function g(x):
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
Answer:
Slope of f(x) is greater than slope of g(x)
g(x) has a greater y intercept
Step-by-step explanation:
Given
f(x) table
[tex]g(x) = 2x + 6[/tex]
Solving (a):
First, we determine the slope of f(x).
From the table, we take any two corresponding values of x and f(x).
Represent f(x) with y
[tex](x_1,y_1) = (-1.-12)[/tex]
[tex](x_2,y_2) = (0.-6)[/tex]
The slope (m) is calculated as thus
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-6 - (-12)}{0 - (-1)}[/tex]
[tex]m = \frac{-6 +12}{0 +1}[/tex]
[tex]m = \frac{6}{1}[/tex]
[tex]m = 6[/tex]
Represent this with m1
[tex]m_1 = 6[/tex]
Calculating the slope of g(x).
The general form of an equation is [tex]y = mx + b[/tex]
Where m represents the slope.
We have that:
[tex]g(x) = 2x + 6[/tex]
By comparing [tex]g(x) = 2x + 6[/tex] with [tex]y = mx + b[/tex]
[tex]m = 2[/tex]
Represent this with m2
[tex]m_2 = 2[/tex]
Comparing both slope, we can say that:
f(x) has a greater than slope of g(x)
Another comparison is that:
Slope of f(x) is 3 times the slope of g(x)
Solving (b): Function with greater y intercept.
The general form of an equation is [tex]y = mx + b[/tex]
Where b represents the y intercept.
First, we need to determine the equation of f(x) using:
[tex]y - y_1 = m(x - x_1)[/tex]
Recall that, from the table of f(x):
[tex](x_1,y_1) = (-1.-12)[/tex]
[tex](x_2,y_2) = (0.-6)[/tex]
[tex]m_1 = 6[/tex]
So:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - (-12) = 6(x - (-1))[/tex]
[tex]y + 12 = 6(x +1)[/tex]
[tex]y + 12 = 6x +6[/tex]
Solve for y
[tex]y = 6x + 6 - 12[/tex]
[tex]y = 6x - 6[/tex]
By comparing this with [tex]y = mx + b[/tex], the y intercept of f(x) is -6
For g(x), we have:
[tex]g(x) = 2x + 6[/tex]
By comparing this with [tex]y = mx + b[/tex], the y intercept of g(x) is 6
Comparing the y intercepts of both functions, g(x) has a greater y intercept because [tex]6 > -6[/tex]

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion [tex]\hat p = 0.70[/tex]
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]
Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]
the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:
[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]
= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)
Christina estimated 188% of 91 by performing these steps. What did she do wrong?
(90) (190 percent) = (90) (100 percent + 90 percent) = (90) (100 percent) + (90) (90 percent) = (90) (1.0) + (90) (0.9) = 90 + 18 = 108.
She rounded 188% up to 190%.
She rounded 91 down to 90.
She incorrectly broke 190% into 100 percent + 90 percent.
She incorrectly multiplied 90 and 0.9.

On the coordinate plane shown, Figure 1 is transformed into Figure 2, which is transformed into Figure3. Figure 1 and Figure 3 are similar by a sequence of transformations. What type of transformation was used to transform Figure 1 into Figure 2?
Answer:
rotation
Step-by-step explanation:
The transformation used to transform figure 1 into figure 2 is a dilation.
What is dilation?A dilation is a transformation that yields a picture that differs in size while maintaining the original image's shape.
Given that, figure 1 is transformed into figure 2, and figure 2 is transformed into figure 3 which s similar to figure 1.
Since figure 1 is similar to figure 3, as per the transitivity property, figure 1 is similar to figure 2.
Since figure 1 is similar to figure 2, the ratio of their side lengths is proportional.
Since the ratio of the side lengths of the two figures is proportional, the transformation is a dilation.
Hence, the transformation used to transform figure 1 into figure 2 is a dilation.

What is the 38th term of 459,450,441,..
Answer:
The 38th term of 459,450,441,.. will be:
[tex]a_{13}=351[/tex]
Step-by-step explanation:
Given the sequence
[tex]459,450,441,..[/tex]
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]450-459=-9,\:\quad \:441-450=-9[/tex]
so
[tex]d=-9[/tex]
The first element of the sequence is
[tex]a_1=459[/tex]
so the nth term will be
[tex]a_n=-9\left(n-1\right)+459[/tex]
[tex]a_n=-9n+468[/tex]
Putting n=38 to find the 38th term
[tex]a_n=-9n+468[/tex]
[tex]a_{13}=-9\left(13\right)+468[/tex]
[tex]a_{13}=-117+468[/tex]
[tex]a_{13}=351[/tex]
Therefore, the 38th term of 459,450,441,.. will be:
[tex]a_{13}=351[/tex]

I NEED IT URGENtLY
Answer: I just took the test and the answer is Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.
Step-by-step explanation:
The solution for the given system of linear equations is (32/69, -10/23).
The given system of equations are 3x-6y=4 and 6x+11y=-2.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Here,
3x-6y=4 ---------(I) and 6x+11y=-2 ---------(II)
Multiply equation (I) by 2, we get
6x-12y=8 ---------(III)
Subtract equation (III) from (II), we get
6x+11y-(6x-12y)=-2-8
⇒ 23y=-10
⇒ y=-10/23
Substitute y=-10/23 in (I), we get
3x-6(-10/23)=4
⇒ 3x+60/23=4
⇒ 3x=4-60/23
⇒ x=32/69
So, solution is (32/69, -10/23)
Therefore, the solution for the given system of linear equations is (32/69, -10/23).
