We wish to determine the proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes. A random sample of 242 small- to medium-sized streams is selected and it is found that 55 of them have runoff from hog farms. Which of the following is the value of the parameter of interest in this setting?
a. 0.555
b. 0.03298
c. 0.445
d. The value of the parameter of interest cannot be determined from the given information.
Answer:
The value of the parameter of interest in this setting is:
d. The value of the parameter of interest cannot be determined from the given information.
Step-by-step explanation:
To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina. We also require the population proportion of these streams, which have runoff from hog farms. But in this situation, the information is lacking. Instead, we are given information about the sample, which only produces statistics. For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.

Fill in the missing number to complete the equivalent fraction show what you multiply or divided by convert each improper fraction to a mixed number or whole number
Answer:
3a) 5/45 you divide by 5
3b) 6/7 you divide by 2
3c) 2/7 you divide by 9
3d) 2/5 you divide by 9
4a) 6
4b) 1 1/4 or 5/4 (both are correct)
4c) 3 1/2 or 3 3/6 (both are correct)
4d) 5 1/8
The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number

Find x. Round to the nearest tenth.

Answer:
7.5
Step-by-step explanation:
The ratio between the two numbers in each set are the same, so the process used to get from 4 to 6 could also be used to find x. 6/4=1.5, so 4*1.5=6. Multiplying 5 by 1.5 would get x. 5*1.5=7.5, so x=7.5.
To eliminate the x terms and solve for y in the fewest steps, by which constants should the equations be multiplied
by before adding the equations together?
First equation: 6x-5y=17
Second equation: 7x + 3y = 11
The first equation should be multiplied by 3 and the second equation by -5.
O The first equation should be multiplied by 3 and the second equation by 5.
O The first equation should be multiplied by 7 and the second equation by -6.
The first equation should be multiplied by 7 and the second equation by 6.
Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.
Simultaneous equation6x - 5y = 17
7x + 3y = 11
Using elimination method
Multiply equation (1) by 3 and (2) by 518x - 15y = 51
35x + 15y = 55
Add the equation18x + 35x = 51 + 55
53x = 106
x = 106/53
x = 2
Substitute x = 2 into6x - 5y = 17
6(2) - 5y = 17
12 - 5y = 17
-5y = 17 - 12
-5y = 5
y = 5/-5
y = -1
Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

Step-by-step explanation:
[tex]3\cdot10^8\dfrac{m}{s}\\\\1km=1,000m\to1m=0.001km\\1h=3,600s\to1s=\dfrac{1}{3600}h[/tex]
therefore

The values of x and y are directly and one pair of values are given.
write an equation that relates x and y. simplify completely.
x= -4, y =6
Answer:
The relation is [tex]y = -1.5x[/tex]
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:
[tex]y = ax[/tex]
In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So
[tex]y = ax[/tex]
[tex]6 = -4a[/tex]
[tex]a = -frac{6}{4}[/tex]
[tex]a = -1.5[/tex]
So
The relation is [tex]y = -1.5x[/tex]

According to Wikipedia, the average weight of an adult male in the U.S. is 197.7 pounds with a standard deviation of 18 pounds, while the average adult female weighs 168.7 pounds with a standard deviation of 15 pounds. Both weights vary according to a Normal distribution.
7.) If you randomly selected one adult woman, what is the probability that her weight exceeds (is higher than) 130 pounds?
Suppose you randomly selected one adult male and one adult female from the entire U.S. population. Let the variable D = the difference in their weights (male – female).
8.) Calculate and interpret the mean of D.
9.) Interpret your answer from #8 in context.
10.) Calculate the standard deviation of D.
11.) Calculate the probability that the randomly selected male would weigh less than the randomly selected female.

Answer:
-8x² - 6
Step-by-step explanation:
-1 + 2 will give us "+1"
+1 - 7 will give us "-6"
The answers given already are correct as they are properly matched, so we are left with the following to complete:
Thus,
-4y³ + 4y³ will give us "0".
We would be left with:
-3x² - 6 - 5x²
Collect like terms again
-3x² - 5x² - 6
-3x² - 5x² will give us "-8x²"
Final result would be:
-8x² - 6

Step-by-step explanation:
ΔLNM and ΔLKN are 30°- 60°- 90° triangles
We have to find the length of LN before we can find the length of MN.
In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3
Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.
LN = √3 times the shorter leg
3 × √3 = 3√3
LN = 3√3
We now know the length of the longer leg in ΔLNM (3√3)
MN would be 3√3 × √3
3√3 × √3
= 3√9
= 3 × 3 = 9
MN = 9
ΔLKM is also a 30° - 60° - 90° triangle
The short leg is 6 m
The hypotenuse would be 12 m
The longer leg would be 6√3
Perimeter: 6 + 12 + 6√3
The perimeter is 18 + 6√3
Area: 1/2 × b × h
b = 6√3
h = LN = 3√3
6√3 × 3√3
18√9 = 18 × 3 = 54
Area: 54 m²

Draw a balanced hanger diagram for the equation 2x=4
Step-by-step explanation:
3360832553 ____ pass___ wZE2XQ
Answer:
See the attached picture.
Step-by-step explanation:
I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.
See the attached picture.
There are 2 x's on the left and 4 1's on the right.
This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.
Each unit of different size should be in a different shape.
The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.
Hope this helps.
