The U.S. Mint has as specification that pennies have a mean weight of 2.5 g. A sample of 37 new pennies have a mean weight of 2.49910 g and a standard deviation of 0.01648 g. Use a 0.05 significance level to test the claim that this sample is from a population with a mean weight equal to 2.5 g. Use Table A-3 to find the range of values for the P-value.

Answer:
63
Step-by-step explanation:
A triangle always has a total of 180 degrees
Since we know two we can solve for x
76+41+x=180
x=63
Answer:
63
Step-by-step explanation:
Basically there is 180 degrees in every triangle. So all you do is
180-76=104
104-41= 63
so your answer is 63 degrees.
Find the missing side length.
Answer:
4
Step-by-step explanation:
(6√5)²+x²=14²
36(5)+x²=196
180+x²=196
x²=196-180
x²=16
x=√16
x=4

1.Assume that 20 squirrels are put in an enclosed wildlife ranch and the squirrel population grows for the next 5 years, as shown in the table.
Year
Rabbit Population
0
20
1
80
2
320
3
1280
4
5120
5
20,480
Write a function that represents this.
2.A second group of 20 squirrels of a different breed is placed on a different ranch. The population of squirrels triples each year. Write an equation to model this situation.
3.Had the second group started with 40 squirrels instead of 20, which population will be bigger by year 3 and by how much?
Answer:
For the first group we have the pairs:
year population
0 20
1 80
2 320
3 1,280
4 5,120
5 20,480
Here we can see that the population quadruples each year
(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)
then the population equation is:
P(0) = 20
P(1) = 20*4
P(2) = (20*4)*4 = 20*4^2
We already can see the pattern, then we can write this relationship as:
P(t) = A*(4)^(t)
Where:
t represents time in years, and A is the initial population, that we know it is 20, then:
P(t) = 20*(4)^t
This is the function that represents the table.
B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:
Q(t) = 20*(3)^t
C) Now, if the initial population of the second group is 40, the equation becomes:
Q(t) = 40*(3)^t
The population by year 3 is given by replacing t by 3, then:
Q(3) = 40*(3)^3 = 1080
And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:
1,280 - 1,080 = 200
So the first group is larger by 200 squirrels.
12 + x/4 > 20
Thank you if you answer!! please just put the answer
Answer:
The answer is x > 32.
Step-by-step explanation:
1) Subtract 12 from both sides.
[tex] \frac{x}{4} > 20 - 12[/tex]
2) Simplify 20 - 12 to 8.
[tex] \frac{x}{4} > 8[/tex]
3) Multiply both sides by 4.
[tex]x > 8 \times 4[/tex]
4) Simplify 8 × 4 to 32.
[tex]x > 32[/tex]
Therefor, the answer is x > 32.

A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples.
Is the owner's estimate reasonable?
The owner’s answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with.
The owner’s estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.

Answer:
B
Step-by-step explanation:
A is not correct because 1 does not equal 1/4 +1/4.
B is correct because 1/4*1 does equal 1/5. (and all the other ones)
C is not correct because 1 does not equal 1/4*1/4
D is not correct because 1/4 does not equal 1-1/4
Answer:
B
Step-by-step explanation:
find the factors of each number. Write the common factor ( CF ) and then state the greatest common factor ( GCF) .
Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
[tex]12=2\times 2\times 3[/tex]
[tex]21=3\times 7[/tex]
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.

Answer:
I. The width is 43.5 inches.
II. The length is 24.5 inches.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Perimeter of rectangle = 136 inches
Translating the word problem into an algebraic expression, we have;
L = W - 19 ......equation 1
Perimeter of rectangle = 2(L + W) ......equation 2
To find the dimensions of the rectangle;
136 = 2(L + W)
Substituting eqn 1 into eqn 2, we have;
136 = 2(W - 19 + W)
136 = 2(2W - 19)
136 = 4W - 38
4W = 136 + 38
4W = 174
W = 174/4
W = 43.5 inches
To find the length;
L = W - 19
L = 43.5 - 19
L = 24.5 inches
Which of the the coordinates is equal to sin (4pi/5) ?
A) x-coordinate of point A
B) y-coordinate of point A
C) x-coordinate of point B
D) y-coordinate of point B
E) x-coordinate of point C
F) y-coordinate of point C
Answer:
Step-by-step explanation:
π/2 < 4π/5 < π
4π/5 is in Quadrant II
sin(4π/5) = y-coordinate of A
The coordinates is equal to sin(4π/5) = y-coordinate of A.
We need to find the coordinates is equal to sin (4pi/5).
Which trigonometric functions are positive in which quadrant?In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Then, we have π/2 < 4π/5 < π
So, 4π/5 is in Quadrant II
Hence, the coordinates is equal to sin(4π/5) = y-coordinate of A.
