Answer:
25 quarters and 4 dimes. Louisa used 21 more quarters than she did dimes.
Step-by-step explanation:
q=number of quarters
d=number of dimes
6.65=.25q+.10d 6.65 (the total) is equivalent to the amount of quarters times .25 (the value of a quarter) plus the amount of dimes times .10 (the value of a dime)
Now divide 6.65 by .25.
26 quarters can be used.
26 times .25 = 6.50
26 quarters is $6.50
29-26=3
3 times .10 = .30
.30+6.50=6.80
This is too much. Let's try taking off one quarter.
Now we have 25 quarters. .25 times 25 = 6.25
29-25=4 (This means there will be 4 dimes if she used 25 quarters, but let's see)
4 times .10 = .40
.40 + 6.25=6.65
6.65 is the total amount she had to pay, so we did it. Solving this showed us that she used 25 quarters and 4 dimes. This equals $6.65, the amount she paid, uses only quarters and dimes, and uses a total of 29 coins.

The standard price night cost at Night-Time Rest Days is $ 26.30 .
Average = Sum of all the observations/Number of observations
Substituting the values in the formula, we get that:
⇒ $ 20.60 = $( 22.45 + 18.55 + 24.50 + 11.20 + x )/5
⇒ $ 20.60 = $ (76.7 + x)/5
⇒ 20.60 × 5 = 76.7 + x
Solving to find the value of x, we get that
⇒ 103 = 76.7 + x
⇒ x = 103 - 76.7
⇒ x = 26.3
Therefore, the standard price night cost at Night-Time Rest Days is $ 26.30 .

Step-by-step explanation:
Both sets of values have an average of 13. Is Set A's standard deviation smaller, larger, or about the same as Set B's? Set A: 1 2 3 23 24 25 Set B: 9 10 11 14 16 18
a.)About the same
b.)Not enough information provided to tell
c.)Larger
d.)Smaller
Set A's standard deviation is larger than that of Set B (option c).
What are the standard deviations?
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. Standard deviation is a measure of variation of a dataset.
In order to determine the standard deviation, take the following steps:
Determine the average of the observation:Determine the difference between each value and the average and then square the result:Determine the average of the sum of the squared differences and then find the square root of the mean:Standard deviation of Set A:
(1 - 13)² + (2- 13)² + (3- 13)² + (23- 13)² + (24- 13)² + (25 - 13)²
144 + 121 + 100 + 100 + 121 + 144 = 730
√730 / 6 = 11.03
Standard deviation of Set B:
(9 - 13)² + (10- 13)² + (11- 13)² + (14- 13)² + (16- 13)² + (18 - 13)²
16 + 9 + 4 + 1 + 9 + 25 = 64

both of those days.
The lengths of the candlesticks for September 8 and 11 are approximately the same because this physical object stands in for the price range between the opening and closing prices for that trading day.
The close was lower than the open if the true body is filled in or is completely black. Real bodies that are empty indicate that the close was higher than the open.
Let's consider a case study over a longer time frame, say a week. In this example, the candle records prices from Monday through Friday of the work week. The price at which the market starts on Monday at 9:15 a.m., the first business day of the week, will be the opening price. The highest and lowest prices ever recorded will be set during that particular week.
Over a century before the West created the bar and point-and-figure charts, candlestick charts were invented in Japan. While there was a correlation between rice price and supply and demand in the 1700s, a Japanese man by the name of Homma found that traders' emotions had a significant impact on the markets.

with reference to the figure below, find x, y, z, t such that n(U) =50, n(A) = 25, n(B) = 13 and n(A’nB’) = 12
(pls help i’m gonna cry)
Accordingly the Venn diagram The required values of x = 12 , y = 13 , z = 24 and t = 13.
A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items.
In Venn diagram, if two sets A and B do not intersect, then n(A∩B)=0 and n(A∪B) = n(A) + n(B).
Given: n(U) = 50, n(A) = 25, n(B) = 13 and n(A'∩B')=12
We have to determine the values of x, y, z, and t.
According to the given figure,
n(A') = n(U) - n(A)
n(A')= 50 - 25
n(A') = 25
n(B') = n(U) - n(B)
n(B') = 50 - 13
n(B') = 37
n(A∩B) = n(A') - n(A'∩B')
n(A∩B) = 25 - 12
n(A∩B) = 13
So, y = n(A∩B) = 13
As in the Venn diagram, we know that,
x + y = n(A')
x = n(A') - y
x = 25 - 13
x = 12
y + z = n(B')
13 + z = 37
z = 37 - 13
z = 24
t = n(U) - [n(A) + n(B)]
t = 50 - [25+13]
t = 50 - 37
t = 13
Therefore, the values of x, y, z and t are 12, 13, 24, and 13.

There are 7 pairs of whole numbers that have a sum of 12.
Given that we need to determine the pairs of whole numbers can you find that have a sum of 12.
To find the pairs of whole numbers that have a sum of 12, we can simply list all the possible combinations and count them.
Let's consider two whole numbers, x and y, such that x + y = 12. Since the numbers should be whole numbers and greater than or equal to 0, we have the following options:
x = 0, y = 12
x = 1, y = 11
x = 2, y = 10
x = 3, y = 9
x = 4, y = 8
x = 5, y = 7
x = 6, y = 6
So, there are 7 pairs of whole numbers that have a sum of 12.
These pairs are (0, 12), (1, 11), (2, 10), (3, 9), (4, 8), (5, 7), and (6, 6). Each of these pairs satisfies the condition that both x and y are whole numbers and their sum is equal to 12.
Note: We only consider x and y values up to 6 since beyond that, the sum would exceed 12, and we are only looking for pairs with a sum of 12.

What is normal distribution?
A probability distribution known as a "normal distribution" is symmetric about the mean and indicates that data that are close to the mean are more likely to occur than data that are far from the mean.
Given that:
μ= 1.4
σ=4.6
We know the formula of normal distribution is z = (x-μ)/σ
[tex]P(0 < x < 3)=P(x < 3)-P(x < 0)[/tex]
For [tex]P(x < 3)[/tex]
[tex]z=\frac{3-1.4}{4.6} \\z=0.35[/tex]
By using the z-table [tex]P(x < 3)=0.6368[/tex]
For [tex]P(x < 0)[/tex]
[tex]z=\frac{0-1.4}{4.6}\\z=-0.30[/tex]

that models the path of the object with a maximum height of 200 feet, represented by a vertex of (25, 200) , landing at the point
(55.0)
Answer:
Bonjour,
Step-by-step explanation:
y=k*(x-25)²+200
0=k*(55-25)²+200 => k=-2/9
y=-2/9(x-25)²+200
The a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.
What is defined as the parabolic path?A projectile's trajectory angle is defined as a parabolic path. A parabola is just a curve that represents a quadratic equation graphically. The initial velocity of a projectile is either horizontal or upward at such an angle. If a projectile starts out straight up, it will end up straight down. It's not much of a parabola because it's squished into the a straight line.For the given question;
The maximum height of the object which is launched from the top of a hill is 200 m.
The equation of the parabola is -
y=a*(x-h)²+k
(h,k) = vertex = (25, 200)
y = a*(x-25)²+200
Put (x,y) = (55,0)
0=a*(55 - 25)²+200
=> a = -2/9
Now put the value of 'a' and form the equation.
y = -2/9(x-25)²+ 200
Thus, the a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.

Step-by-step explanation:
SP is part of a line and line is 180°
so:
m∠PQR + m∠RQS= 180°
(3x-5) + ( x+1) = 4x-4=180
4x = 184
x= 46
m∠PQR = 3X-5 = 3(46)-5 =133
Answer:
133
Step-by-step explanation:
Supplementary angles are angles that sum to 180°, meaning they form a straight line.
Solving for x
Since we know that these 2 angles will sum to 180 (remember they are supplementary) we can add their expression together and set it equal to 180.
(3x-5) + (x+1) = 180Next, combine like terms.
4x - 4 = 180Add 4 to both sides
4x = 184Divide by 4
x=46Solve for m∠PQR
Now that we know the value of x, we can find the measure of PQR. Simply plug 46 in for x and solve.
3(46) - 5 = 133This means that m∠PQR = 133°.
