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?
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

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots. Which is the total weight of the lettuce and carrots in ounces?
A. 10 ounces
B. 12 ounces
C. 40 ounces
D. 72 ounces
The total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We have:
Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots.
As we know:
1 pounds = 16 ounces
Amount of lettuce = 8 ounce
Amount of carrots = 2 pounds = 2×16 = 32 ounces
Total weight of the lettuce and carrots in ounces = 8 + 32 = 40 ounces
Thus. the total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

5. PA license plates have 3 letters followed by 4 numbers.
a. If the same letter or number can be repeated, how many can be made?
b. If the same letter CANNOT be repeated, how many can be made?
Answer:
A. 175,760,000
B. 156,000,000
Step-by-step explanation:
For part A:
There are 26 letters in the alphabet. Therefore, if there are 3 spots to use 26 letters, that is represented as [tex]26^3[/tex]. As for numbers, there are 10 digits from 0-9. So if there are 4 spots for numbers, the total possible number of sequences is [tex]10^4[/tex]. So you simply multiply [tex]26^3[/tex] and [tex]10^4[/tex] to get 175,760,000 possible combinations.
For part B:
If the same letter can't be repeated, instead of using an exponent, we have to use a factorial, but only for the 3 digits required in the license plate. These are called permutations and can be expressed as [tex]_2_6P_3[/tex], which is the same as saying 26 x 25 x 24. Since there is no change to number of numbers, that remains the same.
[tex]_2_6P_3 * 10^4 =26*25*24*10^4=156,000,000[/tex]

Answer:
425 grams divided by 28.3 = 1 ounce is about 15 ounces
Step-by-step explanation:
Since there are 425 grams in total and 28.3 GRAMS = 1 OUNCE that means. Every 28.3 grams in the total of 425 grams are ounces so we divide it by the 28.3 in order to find the ounces since every 28.3 grams are ounces!

Annie buys some greeting cards. Each card costs $1.75. She pays with a twenty dollar bill. Let n represent the
number of greeting cards Annie buys. Write an expression that represents the amount of change Annie should
receive
Answer:
20÷1.75= 11
so Annie gets 11 cards 1.75×11=19.25
20-19.25=0.75
so Annie will get 75¢
Heather received a 90 gift card for a coffee store. She used it in buying some coffee that cost $8.49 per pound. After buying the coffee, she had $56.04 left on
her card. How many pounds of coffee did she buy?
pounds
2
Answer:
Latoya bought 4 pounds of coffee.
Step-by-step explanation:
it sounds like you want to know how many pounds of coffee Latoya bought. First, let's figure out how much she spent. Subtract the amount she has left from the amount she started out with:
90 - 57.68 = 32.32
Latoya spent $32.32 on coffee. Since it cost $8.08 per pound, we can divide the total cost by 8.08 to figure out how many pounds she bought:
32.32/8.08 = 4
Latoya bought 4 pounds of coffee.

5. Ten workers are fencing a 25 m by 28 m stadium. They had finished fencing 95 m.
How many more metres of fence co they need to build?
A. 11 m
C. 148 m
B. 106 m
D. 201 m
Answer:
A. 11 m
Step-by-step explanation:
Given that
the ten workers are fencing 25 m by 28 m
And, they finished the fencing 95 m
We need to find out the number of more meter of fence that could be developed
So,
= (25+25) + (28+28)
= 106 - 95
= 11
Hence, 11 more meters should be build
Therefore the correct option is A.

Solve for x.
2x + 15
3x - 20
x = [?]
Answer:
x= 7
3x-20
2x+15
you would add 3x+2x equals 5x and 20 +15= 35
5x+35
35 divided by 5 is 7 and then on the 5x divide by 5 and leaves x=7
Answer:
35
Step-by-step explanation:
Angles 2x + 15 and 3x - 20 are adjacent angles.
Adjacent angles are equal.
3x - 20 = 2x + 15
3x - 2x = 15 + 20
x = 35

the measure of an angle is fifty nine times the measure of its supplementary angle. What is the measure of each angle
9514 1404 393
Answer:
177°, 3°
Step-by-step explanation:
If the smaller angle is s, then the sum of the two angles is ...
s + 59s = 180°
s = 180°/60 = 3° . . . . . divide by the coefficient of s
59s = 177° . . . . . . . . . find the larger angle
The two angles are 177° and 3°.
