Step-by-step explanation:
i think its y=5 because the bottom one equals 9
Answer:
A or y = 5
Step-by-step explanation:
So from the last explanation, we know that each row or column must be 9. The middle row and middle column must also be 9 so:
6 + y - 2 = 9, and 0 + y + 4 = 9
4 + y = 9, and 4 + y = 9
So we can conclude that:
Y must be 5

Answer: ______
Answers
The range of values that satisfy the given inequalities, 8x - 11 > 5 and 15(6x+2) > -150, is x > -2 OR x > 2
Solving Linear Inequalities: Determining range of valuesFrom the question, we are to determine the range of values which satisfy the given inequalities.
The given inequalities are
8x - 11 > 5 and 15(6x+2) > -150
To determine the range of values that satisfy the inequalities, we will solve each of the inequalities separately
Solving 8x - 11 > 5
Add 11 to both sides
8x - 11 + 11 > 5 + 11
8x > 16
Divide both sides by 8
8x/8 > 16/8
x > 2
Solving 15(6x+2) > -150
Divide both sides by 15
15(6x+2)/15 > -150/15
6x + 2 > -10
Subtract 2 from both sides
6x + 2 - 2 > -10 - 2
6x > -12
Divide both sides by 6
6x/6 > -12/6
x > -2
Putting the two solutions together,
x > -2 OR x > 2
Hence, the solution is x > -2 OR x > 2

An ocicat eats $\frac 35$ of a pound of food daily. How many ocicats can a $19\frac 12$-pound bag of food feed for one week?
Answers
Answer:
First, we need to determine how many pounds of food the ocicat eats in a week. There are 7 days in a week, so the ocicat eats $\frac 35$ pounds/day * 7 days/week = $\frac{7}{5}$ pounds/week.
Next, we need to divide the total amount of food in the bag by the amount of food that the ocicat eats in a week to determine how many weeks the bag of food will last. The bag of food weighs 19 1/2 pounds, so it will last for a total of 19 $1/2 pounds / $7/5 pounds/week = $33/7 weeks.
Finally, we need to divide the total number of weeks that the bag of food will last by the number of ocicats that the food will feed to determine how many ocicats the bag of food will feed for one week. The bag of food will feed $33/7 weeks / 1 week/ocicat = $33/7 ocicats.
Therefore, the 19 $1/2-pound bag of food will feed $33/7 ocicats for one week.

_______________ dunes form where the wind direction is variable in all directions. These dunes are the largest of the desert and can often be over 650 ft high. The sand supply can range from limited to quite abundant. It is the variation in wind direction that forms this dune.
Answers
The description provided suggests the formation of star dunes in desert environments. Star dunes are the largest type of dunes, reaching heights of over 650 ft.
Star dunes are a type of sand dune characterized by multiple radiating arms that extend in different directions from a central point. They are often found in desert regions where the wind patterns are highly variable, blowing from different directions. The wind's variability causes the sand to accumulate and form the distinct star shape of the dune.
Due to the shifting wind patterns, the arms of the star dune can change in length and direction over time. The sand supply available for the dune formation can also vary, range from limited to abundant. These factors contribute to the growth and size of star dunes, making them the largest dunes found in deserts.

*this could be wrong so check my work
Answer:
x = 12
Explanation:
8 : x
12 : 18
to find the value of x, we need to convert 12 into 8. since they both have a common factor of 4, we can divide 12 by 3 to get 4, and then multiply it by 2 to get 8. in numerical terms, this is:
12 ÷ 3 = 4
4 × 2 = 8
now, we can do the same for 18.
18 ÷ 3 = 6
6 × 2 = 12
thus, 12 : 18 is equivalent to 8 : 12. x = 12.

What are Fractions?Fraction are numbers of the form \(\frac{a}{b}\) where a and b are real numbers. It is represented as a portion or part of a whole.
The number on the top is called numerator and the number on the bottom is called denominator.
There are 10 equal parts of bread and each child takes 0.2 part.
Total parts of the bread = 10
Part each child takes = 0.2 = \(\frac{2}{10}\)
2 parts out of 10 are taken by each child.
Remaining are \(\frac{8}{10}\) parts.
\(\frac{2}{10}\) × 4 = \(\frac{8}{10}\)
Remaining parts can be shared by 4 children.
Hence number of children who can share the bread if each takes 0.2 parts = 5

Using the slope concept, it is found that the change in elevation was of -699 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem, we have that:
The vertical change is of h.The horizontal change is of 10,000 feet.The angle is of -4º.Hence:
tan(-4º) = h/10000

The probability of winning a certain lottery is 1/64,481. For people who play 669 times, find the standard deviation for the number of wins. ?
A) 0.1
B) 2.6
C) 1.1
D) 0.3
E) None of These
Answers
The probability of winning a certain lottery is p = 1/64,481. For a single play, the expected number of wins is E(X) = 1*p + 0*(1-p) = p.
The variance of the number of wins for a single play is\(Var(X) = p(1-p) = 1/64,481 * 64,480/64,481 = 64,480/64,481^2\).
For 669 plays, the expected number of wins is 669p and the variance of the number of wins is \(669Var(X) = 669(64,480/64,481^2) = 668.99/64,481\).
The standard deviation is the square root of the variance, so the answer is approximately sqrt(668.99/64,481) = 0.309.
Therefore, the closest answer choice is D) 0.3.

Calculating the pattern for the expressionThe pattern in the question is given as
8, 17, 26, 35, 44, …
In the above expressions and pattern, we can see that
The current term is added to 9 to get the next term
From the above, we have the following
First term, a = 8Common difference, d = 9This means that the pattern is an arithmetic sequence with the following features
a = 8
d = 9
An arithmetic sequence is represented as
f(n) = a + (n - 1)d
When the values of "a" and "d" are substituted in the above equation, we have the pattern to be
f(n) = 8 + (n - 1)9
So, we have
f(n) = 8 + 9n - 9
Evaluate
f(n) = 9n - 1
Hence, the pattern for the sequence is 9n - 1

C-Spec, Inc., is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 2 ± 0.004 inches. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 2.001 inches with a standard deviation of 0.002 inch.
Calculate the Cpk for this machine. (Round your answer to 3 decimal places)
Answers
The Cpk (Process Capability Index) for this machine is 0.5 (rounded to 3 decimal places).
To calculate the Cpk (Process Capability Index), we need to consider the specification limits and the process variation.
The Cpk is given by the formula:
Cpk = min[(USL - μ) / (3σ), (μ - LSL) / (3σ)], Where:
USL = Upper Specification Limit
LSL = Lower Specification Limit
μ = Process mean
σ = Process standard deviation
In this case, the Upper Specification Limit (USL) is 2 + 0.004 = 2.004 inches, and the Lower Specification Limit (LSL) is 2 - 0.004 = 1.996 inches.
Given that the process mean (μ) is 2.001 inches and the process standard deviation (σ) is 0.002 inch, we can substitute these values into the formula:
Cpk = min[(2.004 - 2.001) / (3 * 0.002), (2.001 - 1.996) / (3 * 0.002)]
Cpk = min[0.003 / 0.006, 0.005 / 0.006]
Cpk = min[0.5, 0.833]

We have the diameter of the pot = 11 inches then radius = 5.5 inches
Height= 5 inches
Volume = π * (5.5)² * 5
Volume = 475.03 cubic inches
Volume of the square pyramid mold = (1/3) * b² * h
We have Length of the base = 4.5 inches
Height = 2.6 inches
Volume = (1/3) * (4.5)² * 2.6
Volume = 10.17 cubic inches
The Number of candle molds can then be determined as

Find the height in centimeters of a square pyramid with a volume of 144 cm3 and a base edge length equal to the height. Give the approximate answer rounded to 2 decimal places.
Answers
9514 1404 393
Answer:
7.56 cm
Step-by-step explanation:
The volume is given by the formula ...
V = 1/3b²h . . . . where b is the base edge length, and h is the height.
Here we have V = 144 cm³, and b = h. Filling in these values and solving for h, we get ...
144 cm³ = 1/3h³
432 cm³ = h³
h = ∛432 cm ≈ 7.55953 cm
The height of the pyramid is about 7.56 cm.
Answer:
\(7.56cm\)
Step-by-step explanation:
Given that,
base length = Height
so,
\(volume = \frac{1}{3} {b}^{2} h \\ \)
We can also write this as( according to this question)
\(v = \frac{1}{3} \times {b}^{2} \times b \\ v = \frac{ {b}^{3} }{3} \)
let's solve
\(v = \frac{ {b}^{3} }{3} \\ 144 = \frac{ {b}^{3} }{3} \\ 144 \times 3 = {b}^{3} \\43 2 = {b}^{3} \\ \sqrt[3]{432} = b \\ b = 7.55\)
\(base = height = 7.55cm \\ \)
