Challenge A bag contains pennies, nickels dimes, and quarters. There are 50 coins in all of the
coins 18% are pennies and 40% are dimes. There are 2 more nickels than pennies. How much
money does the bag contain
The bag contains S
Answer:
The bag contains $5.14
Step-by-step explanation:
18% of 50 = (.18)(50) = 9 pennies
40% of 50 = (.40)(50) = 20 dimes
2 more nickels than pennies = 9 + 2 = 11 nickels
40 coins so far, so 50 - 40 = 10 quarters
Total value:
9 x ($0.01) = $0.09 for pennies
20 x ($0.10) = $2.00 for dimes
11 x ($0.05) = $0.55 for nickels
10 x ($0.25) = $2.50 for quarters
Grand total value = $5.14
What are the center and radius of the circle defined by the equation
x2 + y2 - 6x+10y + 25 = 0 ?
O A. Center (3,-5); radius 9
B. Center (-3, 5); radius 3
C. Center (3,-5); radius 3
D. Center (-3, 5); radius 9
Answer: Center (3,-5); radius 3
Step-by-step explanation:
The center and radius of the circle defined by the equation is (3, -5) and 3.
What is Equation of Circle?The standard equation of a circle is given by:
(x-h)² + (y-k)² = r²
Where (h,k) is the coordinates of center of the circle and r is the radius.
We have Equation,
x² + y² -6x + 10y +25= 0
Now, rearranging the terms
x² -6x + y² +10y +25 = 0
Now, add and subtract 9
x² -6x + 9 + y² +10y +25 -9 = 0
(x-3)² + (y+5)² = 3²
(x- 3)² + y(-(-5))² = 3²
So, the Centre of Circle is (3, -5) and the radius is 3.

Answer:
D. They have the same slope, and the same y-intercept so they have infinitely many solutions.
Step-by-step explanation:
Graphing these lines shows that both lines are the exact same line, and cannot have a point of intersection. Solving the equations shows you a value that is ultimately always correct; such as 0=0. This can be used as proof that "They have the same slope, and the same y-intercept so they have infinitely many solutions" because either equation can be rearranged to equal the other.

Answer:
Step-by-step explanation:
Can a person train to become better at holding their breath? An experiment was designed to find out. A group of 12 volunteers were randomly assigned to 1 of 2 groups. The 6 volunteers assigned to group 1 were given breath-holding exercises to perform for 2 weeks. The other group was not given any information about the experiment. At the end of the 2 weeks, all 12 volunteers were individually tested to determine how long they could hold their breath. Here are the data (in seconds):
Group 1: 90, 88, 70, 110, 75, 105
Group 2: 40, 48, 35, 50, 55, 62
The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than the true mean amount of time volunteers without training held their breath. The researcher tests H0: μ1 – μ2 = 0, Ha: μ1 – μ2 > 0, where μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. The conditions for inference are met. The standardized test statistic is t = 5.44. What is the P-value of this test closest to?
Answer is A, 0
The null hypothesis may be significantly rejected. Choose A, 0, for the closest response.
What does "true mean" refer to?In statistics, the term "true mean" refers to the true mean of a population or set of data.
It is typically unknown; hence it is estimated using inferential statistics using a sample.
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.
Given the data values:
Group 1: 90 88 70 110 75 105
Group 2: 40 48 35 50 55 62
For group 1, n1 = 6
group 2, n2 = 6
Given that H_o= u1 - u2 = 0
H_a = u1 - u2 > 0
To find the t-test about the difference, we would use the formula to solve.
The totals are displayed below:
x1 = 538
x2 = 290
(x1-x2) ² = 1253.3334
x2-x2= 0
(X2-x2) ² =481.3334
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.

Find the values of m and n.
Answer:
[tex]m=46^{\circ},\\n=22^{\circ}[/tex]
Step-by-step explanation:
From the isosceles-base theorem, the base angles of two equal legs in a triangle must be equal. Thus, we can set the up the following equation to solve for [tex]n[/tex]:
[tex]136+n+n=180,\\136+2n=180,\\2n=44,\\n=\boxed{22^{\circ}}[/tex]
Now that we've found [tex]n[/tex], we can set up the following equation with respect to the largest triangle:
[tex]90+n+m+n=180,\\90+22+m+22=180,\\134+m=180,\\m=\boxed{46^{\circ}}[/tex]
Answer:
M = 46°
N = 22°
Step-by-step explanation:
Value of M:
Sum of angles in triangle = 180°
180° - 90° - (180° - 136°) = m
90° - 44° = m
m = 46°
Value of N:
The triangle is isosceles (marked by the two congruent lines with the tick)
That means that the other two angles, are the same
180° - 136° = 2n
44° = 2n
n = 22°

The tables that represent the same function are:
x|y

For two tables to represent the same function, they must have the same output for the same input. In the first table, input 4 gives output 8 and input 6 gives output 7. In the second table, input 2 gives output 8 and input 8 gives output 5. Therefore, these two tables represent the same function.
The other tables do not represent the same function, as they have different outputs for the same input values.

auntion to find the time it takes to copy a 50-page
Nii
Answer:
288 points
2 minutes
5 minutes
Step-by-step explanation:
Given that :
Average point per game = 18 points
Number of games played = 16
Total points claimed = number of games played * average points per game
Total points = 18 * 16 = 288 points on average
Print rate = 12 pages per minute
Copying rate = 10 pages per minute
To print a 24 page research paper :
Time taken = number of pages / printing rate
Time taken = 24 / 12 = 2 minutes
To copy a 50 page paper :
Time taken = number of pages / copying rate
Time taken = 50 / 10 = 5 minutes

Which function is shown in the graph below? On a coordinate plane, a function is shown. The curve starts in quadrant 4 and curves up to quadrant 1.

Answer:
c
Step-by-step explanation:
The y-values of the graph increases as the value of x increases, which
indicates that a characteristic of the base of the logarithm function.
Correct response:
The function that corresponds with the graph is; [tex]\underline{\mathrm{y = log_6 x}}[/tex]How can the function of a log graph be determined?The given points on the graph are;
The point where the graph starts = Quadrant 4
Direction of the graph = From quadrant 4 to quadrant 1
Points on the graph are;
(0.5, -0.4), (1, 0), and (6, 1)
The given options are;
[tex]y = \mathrm{log_{\frac{1}{6} } x}[/tex]
[tex]y = \mathrm{log_{0.5} x}[/tex]
[tex]y = \mathrm{log_1 x}[/tex]
[tex]y = \mathrm{log_{6} x}[/tex]
From the shape of the graph, in which, log x increases as x increases, therefore;
The base, b, of the logarithm is larger than 1, given that we have;
[tex]\mathbf{log_bx} = y[/tex]
[tex]\mathbf{b^y} = x[/tex]
From the given coordinate points, x increases as y increases, therefore;
b > 1
The possibly option is therefore, y = log₆x
Verifying, we have;
At x = -0.4, y = 0.5
[tex]b^y = x[/tex]
[tex]6 ^{(-0.4)}[/tex] ≈ 0.488
Therefore, the point (0.5, -0.4) is close to the graph of y = log₆x
At the point (1, 0), we have;
6⁰ = 1
Therefore, the point (1, 0), is on the graph of y = log₆x
At the point (6, 1), we have;
6¹ = 6
Therefore, the point (6, 1) is on the graph of y = log₆x
The function of the graph is therefore;
