72-30=42
42/6=7
Step-by-step explanation:
Good luck! <3
Answer:
(72-30) divided by 6
Step-by-step explanation:
You subtract 30 from 72 because Ms.Correa is going to keep them. Then you divide that by 6 of her children to get your answer. 72-30=42, 42/6 = 7

Answer: I think its 0.55
Step-by-step explanation: if you do 25 times 0.55 because quarter's are 25 cents it equals 13.75
The number of quarters in the piggy bag will be 55.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure. Unit conversion is the process of changing a quantity's measurement between different units, frequently using multiplicative conversion factors.
Given that Dominique has $13.75 in her piggy bank. All of the money is quarters.
The number of the quarters will be calculated as:-
1 dollar ⇒ 4 quarters
13.75 dollars ⇒ 13.75 x 4 quarters
13.75 dollars ⇒ 55 Quarters
Therefore, the number of quarters in the piggy bag will be 55.

Answer:
True.
Step-by-step explanation:

Which of the following subsets of ℝ3×3 are subspaces of ℝ3×3? A. The 3×3 matrices of rank 2 B. The 3×3 matrices in reduced row-echelon form C. The 3×3 matrices with trace 0 (the trace of a matrix is the sum of its diagonal entries) D. The diagonal 3×3 matrices E. The 3×3 matrices with all zeros in the second row F. The invertible 3×3 matrices
Answer:
The answer is "Option C, Option D, and Option E".
Step-by-step explanation:
In point, A: Its matrix (aA+bB) for A, B matrices of rank 2 is not always of rank 2. for Rank(A+B) is smaller or equivalent to RankA+B.
In point B: The two matrices, A, B, and each entry is equal to or larger than zero. Then, take a = -1 = b, and so all entries (aA+bB) belong to the subset are less than or equal to Zero.hence.
In point C: We get the matrix (aA+bB) for A, B matrices with trace 0. Trace zero. (aA + bB) trace is (a×trace(A) + b×trace(B)) thus null.
In point D: For Both A and B, the matrix (aA+bB) is again diagonal for two diagonal matrices.
In point E: For Both A and B matrices, each insertion in second row zero will also have the second-row matrix (aA+bB) as zero.
In point F: In this case, A and B must become two reduced raw echelons, so that A+E is also a reduced raw shape.

Answer:
7.8 * 10 ^-3
Step-by-step explanation:
( 1.3* 10 ^-5) ( 6 * 10^2)
Multiply the numbers
1.3 * 6 = 7.8
Multiply the exponent terms, remembering we add the exponents, when we multiply
10 ^ -5 * 10 ^2 = 10 ^( -5+2) = 10 ^-3

Complete Question
You want to test whether salaries for male doctors are different from salaries for female doctors, using a random sample of 100 male and 100 female doctors. The statistical test you should use is
a. t-Test: Two-Sample Assuming Equal Variances
b. t-Test: Two-Sample Assuming Unequal Variances
c. z-Test: Two Sample for Means
d. t-Test: Paired Two Sample for Means
Answer:
The correct option is C
Step-by-step explanation:
From the question we can see that
The salaries for male doctors is independent of The salaries for female doctors
Hence the samples obtained from both populations are independent
Also both of the random samples are sufficiently large.
So given that the samples are independent and sufficiently large then the best statistical test to use is z-Test: Two Sample for Means

The point-slope form of the equation of the line that passes through (-4, -3) and (12, 1) is y-1 =1/4 (x – 12). What
is the standard form of the equation for this line?
Answer: y=1/4x - 2
Step-by-step explanation: The easiest way to solve this would be to graph it in point-slope form then find the slope and y-intercepts. Try using desmos for that method. There are multiple ways to convert point-slope to standard, however, and I would suggest talking to your teacher to see which method s/he prefers you use. Let me know, and I can help you more if you need it.

Answer:
648
Step-by-step explanation:

volume of the cylinder before melted
v=Pi×18²×40
v=40715.04cm³
Volume of the smaller cylinder
v=Pi×2²×5
v=62.83
40715.04÷62.83
=648.019

12x+8y=28 in slope intercept form
Answer:
Step-by-step explanation:
y = − 3 /2 x + 7/ 2
Step-by-step explanation:
The given expression is:
12x + 8y = 28
Problem;
Express in slope-intercept format;
Solution:
The equation of a straight line is given as;
y = mx + c
where y is the y-coordinate
m is the slope
x is the x-coordinate
c is the intercept
To solve this problem simply express the given equation as that of a straight line.
12x + 8y = 28 in the form y = mx + c
12x + 8y = 28
take 12x to the other side;
8y = 28 - 12x
divide by 8 to isolate the y;
[tex]\frac{8y}{8} = \frac{28}{8} - \frac{12x}{8}[/tex]
y = [tex]\frac{7}{2} - \frac{3x}{2}[/tex]
Re-arranging gives;
y = [tex]\frac{-3x}{2} + \frac{7}{2}[/tex]
This is the slope-intercept form.

Terminating vs. Repeating
Some rational number, such as 1/2, 3/8, and 2/5 have a finite
decimal (terminating decimal); while others, such as 1/3, have
infinite decimal representation (repeating decimal).
For which positive whole numbers, n, is the decimal
representation of 1/n finite? For which is it infinite? Describe
the pattern, if there is one.
Answer:
If the positive whole number is a multiple of 3, one divided by that number will always be a non-terminating decimal.
Use the graph below to answer the following question:
What is the average rate of change from x = −4 to x = 1?
A.-3
B.-1
C.0
D.1
Answer:
The answer is B.-1
Step-by-step:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.p explanation:

Answer:
y = -6x - 5
Step-by-step explanation:
To find the equation using the point-slope equation, we need the slope and the y-intercept of the line
Finding the slope of the line:
We will calculate the slope between these 2 points: (-1 , 1) and (0 , -5)
Slope = Rise / Run
Rise of the line = y1 - y2
Rise = 1 - (-5)
Rise = 1 + 5
Rise = 6
Run of the line = x1 - x2
Run = -1 - 0
Run = -1
Slope of the line:
Slope = Rise / Run
Slope = 6 / -1
Slope = -6
Finding the y-intercept:
y-intercept of a line is the y-ordinate of the point where the line intersect the y-axis
From the graph, we can see that the line intersects the y-axis at (0 , -5)
y-coordinate of the point = -5
y-intercept = -5
Equation of the line:
This is the general formula of the slope-intercept:
y = mx + b (where m is the slope of the line and b is the y-intercept )
Replacing the variables
y = (-6)x + (-5)
y = -6x - 5
