The equation used to determine how many cookies Noah sold is 317 = 13n + 5 where number of cookies Noah sold is 24

Total = Noah + Lin + Jada + Elena + Diego + Andre

317 = n + 3n + (5 + 3n) + {7 + (5 + 3n)} + (n - 4) + {2(n - 4)}

317 = n + 3n + 5 + 3n + 7 + 5 + 3n + n - 4 + 2n - 8

317 = 13n + 5

317 - 5 = 13n

312 = 13n

Answer:

-3

Step-by-step explanation:

1) -x-y = 9

2) -3x+y = 3

By adding 3x to each side on equation #2, you get that y = 3+3x.

Now, we can substitute the value of y into the second equation. If you do this, you will get that [tex]-x-(3+3x)=9[/tex].

Simplifying gives you: [tex]-4x-3=9[/tex]

Adding three to both sides: [tex]-4x=12[/tex]

And finally dividing by negative four: [tex]x=-3[/tex]

You will get x = -3

The amount of water in the barrel is 423,115 cm³.

A cylinder is a three-dimensional object. It is a prism with a circular base. In order to determine the amount of water in the barrel, the volume of the barrel has to be determined.

Volume of a cylinder = nr^2h

Where:

n = 3.14

r = radius = diameter / 2 = 70 / 2 = 35cm

h = height = 1.1m

100cm = 1 meter

1.1 x 100 = 110 cm

Volume of a cylinder = 3.14 x 35² x 110 = 423,115 cm³

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 .

Set A's standard deviation is larger than that of Set B (option c).

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:

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

Answer:

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.

Next, combine like terms.

Add 4 to both sides

Divide by 4

Solve 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.

This means that m∠PQR = 133°.

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.

By using normal distribution, we get probability of gains between 0kg to 3kg is 0.2547

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]

By using the z-table [tex]P(x < 0)=0.3821[/tex]

Substituting [tex]P(x < 3)[/tex] and [tex]P(x < 0)[/tex] in [tex]P(0 < x < 3)[/tex]

we get,

[tex]P(0 < x < 3)=0.6368-0.3821\\P(0 < x < 3)=0.2547[/tex]

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.
