Answer:
h = 20 mm
Step-by-step explanation:
V = πr²h
3920π = π(14²)h = π196h
divide both sides of the equation by π196:

Answer:
A. W
Step-by-step explanation:
The table in which each x-value is related to exactly one y-value is the table that represents a function.
Form the tables given, in table W, every x-value (input) has exactly one y-value (output) that is related to it.
The correct table that represents a function is table W
Functions and TablesFor a table of values to be a function, the input values also known as the domain of the function must NOT have a repeated values.
All values of the domain must have a unique values in the codomain for a table of values to be a function. From the given table, you can see that table X, Y and z all have repeated values in the domain column. This shows that these tables do not represent a functionHence the correct table that represents a function is table W

The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
What is a regression model?A regression model is used to determine the association and correlation between two variables
Using a graphing calculator, the sine regression model of the dataset is:
[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]
To calculate y(30), we substitute 30 for x in the equation.
So, we have:
[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]
Evaluate the product
[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]
Evaluate the difference
[tex]y =20.077 \sin(13.041) + 67.577[/tex]
Evaluate the sine value
[tex]y =20.077 *0.4570+ 67.577[/tex]
Evaluate the product
[tex]y =9.1752+ 67.577[/tex]
Evaluate the sum
[tex]y =76.7522[/tex]
Approximate
[tex]y \approx 76.8[/tex]
Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

There are 150 children attending a summer camp. Students were provided with the option to sign up for swimming and canoeing. The results are shown.
• 71 children signed up for swimming
• 62 children signed up for canoeing
• 28 students signed up for both swimming and canoeing
Part A: Which two-way table summarizes the data?
Answer:
A
Step-by-step explanation: took test
In table, the rows represent whether or not a student signed up for swimming, and the columns represent whether or not a student signed up for canoeing.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To create a two-way table summarizing the data, we need to list the categories we are interested in and then fill in the counts for each combination of categories.
In this case, we are interested in the categories of swimming and canoeing, and we want to know how many students signed up for each combination of the two activities.
Canoeing No Canoeing
Swimming 28 43
Not swimming 34 45
Hence, the rows represent whether or not a student signed up for swimming, and the columns represent whether or not a student signed up for canoeing.

Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals

Use substitution to solve the
following system of equations.
9x + 5y = 32 AND y = -3x + 4
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10

Step-by-step explanation:
3 of the digits 0-9 are chosen randomly by a computer what is the probability that it will choose 3 sequential digits
Answer:
The probability is 1/15
Step-by-step explanation:
Firstly, we need to get the total
number of possible choices
That will be selecting any random 3 numbers from 10 numbers
The number of ways this can be done is 10 C 3 = 120 ways
Now, let us get the possible sequential numbers;
These are ;
0 1 2
1 2 3
2 3 4
3 4 5
4 5 6
5 6 7
6 7 8
7 8 9
Out of the total 120 ; there are 8 possible sequential digits
The probability in this case is thus;
8/120 = 1/15

Adina has a total of $1.65 in nickels and dimes. The number of dimes is 6 more than the number of nickels. How many coins are there of each type?
Choose the correct system of equations needed to solve this problem.
A
0.10d+0.05n=60.10d+0.05n=60.10d+0.05n=6
n+d=1.65n+d=1.65n+d=1.65
B
d=n+6d=n+6d=n+6
0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65
C
n=d+6n=d+6n=d+6
0.10d+0.05n=1.650.10d+0.05n=1.650.10d+0.05n=1.65
D
n=d+6n=d+6n=d+6
0.05n+0.10d=1.650.05n+0.10d=1.650.05n+0.10d=1.65
Answer:
C
Step-by-step explanation:
If you divide 1.65 by 6 you'll get 0.275 so then you'll add d+6n to get d+6 and then you'll solve the question for 6n and you'll get 1.65
