In certain regions of the country, elk can cause damage to agricultural crops by walking through the fields. One strategy designed to limit elk from crossing a field is to surround the field with a fence. Some elk, however, will still be able to bypass the fence. For a period of one month, the number of elk found crossing a sample of fields with a fence was recorded and used to construct the 95 percent confidence interval (2.9,4.4) for the mean number of elk. Assume that the conditions for inference were checked and verified.

Required:
The interval (2.9, 4.4) provides convincing statistical evidence which claims?

Answers

Answer:

The mean number of elk to cross all fields protected by fence is equal to 3.65 per month.

Step-by-step explanation:

Given the confidence interval : (2.9,4.4)

Confidence = xbar ± standard Error

To obtain the mean :

We first calculate the standard error :

Standard Error from confidence interval :

(Upper boundary - Lower boundary interval) / 2

(4.4 - 2.9) / 2

1.5 / 2

= 0.75

Hence, the mean can be obtained as :

(Lower boundary + 0.75) or (Upper boundary - 0.75)

Lower boundary + 0.75 = 2.9 + 0.75 = 3.65

Upper boundary - 0.75 = 4.4 - 0.75 = 3.65

Step-by-step explanation:

Cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

What is Cost price?

" Cost price is defined as the price to be paid at the time of purchase any product."

According to the question,

Initial cost price of shirt [tex]= \$100[/tex]

First discount [tex]= 15\%[/tex]

Discount amount [tex]= 15\%[/tex] of [tex]100[/tex]

                             [tex]= \frac{15}{100} \times 100\\\\= \$15[/tex]

Cost price after first discount [tex]= 100 - 15[/tex]

                                                 [tex]= \$85[/tex]

Second discount [tex]= 20\%[/tex]

Discount amount [tex]= 20\%[/tex] of [tex]85[/tex]

                             [tex]= \frac{20}{100} \times 85\\\\= \$17[/tex]

Cost price after first discount [tex]= 85 - 17[/tex]

                                                 [tex]= \$68[/tex]

Hence, cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

Step-by-step explanation:

Using the standard linear regression relation :

y = bx + c

b slope ; c = intercept ; y = dependent ; x = independent variable.

For finalist between 2004 - 2014 ;

y = 0.024x - 0.328

x = 35

y = 0.024(35) - 0.328

y = 0.512

For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :

y = -0.015x - 0.328

x = 14.

y = -0.015(14) - 0.328

y = - 0.538

Line m is mapped onto line n by a dilation centered at the origin with a scale factor of 2. The equation of line m is 3x−2y=63x-2y=63x−2y=6 . Find the equation for line n showing all work for full credit.

Answers

9514 1404 393

Answer:

  3x -2y = 12

Step-by-step explanation:

The constant in the standard form equation for a line is proportional to the distance of the line from the origin. Dilation by a factor of 2 moves the line to twice its original distance from the origin. The equation of the new line will have the constant 2×6 = 12:

  3x -2y = 12

_____

Additional comment

The actual distance of line ax+by=c from the origin is ...

  d = |c|/√(a²+b²)

The distance from any point in the plane to the line is ...

  d = |ax +by -c|/√(a²+b²)

The previous equation is for the special case of (x, y) = (0, 0), the distance from the origin.

Answer:

Landon's purchase: p +5g = 17.55Lesley's purchase: 4p +2g = 13.50pretzel: $1.80granola bar: $3.15

Step-by-step explanation:

The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.

Landon's purchase

 1 pretzel + 5 bars will cost 1p +5g

 That cost is 17.55, so the equation is ...

     p +5g = 17.55

Lesley's purchase

  4 pretzels + 2 gars will cost 4p +2g

  That cost is 13.50, so the equation is ...

     4p +2g = 13.50

__

To solve, you can subtract the second equation from 4 times the first:

  4(p +5g) -(4p +2g) = 4(17.55) -(13.50)

  18g = 56.70 . . . . collect terms

  g = 3.15 . . . . . . . . divide by 18

Then the cost of a pretzel can be found using the first equation.

  p + 5(3.15) = 17.55

  p = 1.80

The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.

There are 35 red marbles, 8 blue marbles, and 7 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble?

○ 35%
○ 25%
○ 42.9%
○ 70%

Answers

Answer:

70%

Step-by-step explanation: 35/50 equals 0.7

Answer:

70%

Step-by-step explanation:

The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the  probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.

9.03 = x

Step-by-step explanation:

Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;

Cos(46) = [tex]\frac{x}{13}[/tex]

To solve for "x" we would first have to isolate the "x" all to itself.

To isolate the variable, simply multiply 13 to the both sides of "="

=> Cos(46) * 13 = x

=> 9.03 = x

So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.

Relation 1: Not a function

Relation 2: Not a function

Relation 3: Function

Relation 4: Not a function

Step-by-step explanation:

Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.

✔️Relation 1 is NOT A FUNCTION.

Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.

✔️Relation 2 is NOT A FUNCTION:

Rationale: domain value, 9, has several range values assigned to it.

✔️Relation 3 is A FUNCTION:

Rationale: each domain value do not have more than one range values assigned to it.

✔️Relation 4 IS NOT A FUNCTION:

Rationale: the domain value, 6, has two range values, m and d, assigned to it.
