Answer:
1 to 2
Step-by-step explanation:
Imagine the ratio is a fraction: 2/4. Simplify the ratio the same way you'd simplify the fraction. Both the numerator and the denominator are divisible by 2. Divide both by two, and you get 1/2.
Therefore, the simplest ratio is 1 to 2.

In a symmetric histogram, you have the same number of points to the left and to the right of the median. An example of this is the distribution {1,2,3,4,5}. We have 3 as the median and there are two items below the median (1,2) and two items above the median (4,5).
If we place another number into this distribution, say the number 5, then we have {1,2,3,4,5,5} and we no longer have symmetry. We can fix this by adding in 1 to get {1,1,2,3,4,5,5} and now we have symmetry again. Think of it like having a weight scale. If you add a coin on one side, then you have to add the same weight to the other side to keep balance.

Which is true about the product of 3/8 and 7/2. 1.The product is less than 3/8. 2.The product is greater than 1/8 and less that 1/2. 3.The product is greater than 7/2. 4.The product is greater that 3/8 and less than 7/2.
Answer:
4.The product is greater that 3/8 and less than 7/2.
Step-by-step explanation:
The product of 3/8 and 7/2 is:
[tex]\frac{3}{8} * \frac{7}{2} \\\\= \frac{21}{16} = 1\frac{5}{16}[/tex]
This number is greater than 3/8.
It is greater than 1/8 but not less than 1/2.
This number is less than 7/2.
This number is greater than 3/8 and it is less than 7/2.
Hence, the correct options is 4.
Find the solution to this system:
Equation 1: 5x – 2y = -11 (2)
Equation 2: -2x + 5y = 17
Step #2
Multiplying Equation 2 by will create additive
inverses for the x-coefficients.
Answer:
Step 1: Equation 1 can be multiplied by 2, Multiplying Equation 2 by 5
Step 2: divide by 21
Step 3: substitute 3 for y in one of the equations
Step 4: add 6
Step 5: divide both sides of the equation by 5
Step-by-step explanation:
The solution for the given set of equation 5x - 2y = -11 and -2x + 5y = 17 is x = -1 and y = 3.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given set of equation is,
5x - 2y = -11 (1)
-2x + 5y = 17 (2)
Find the value of x from equation (2),
-2x + 5y = 17
2x = 5y - 17
x = (5/2)y -17/2
Substitute the value of x in equation (1),
5((5/2)y -17/2) - 2y = -11
25y/2 - 85/2 - 2y = -11
21y/2 = 63/2
y = 3
Substitute the value of y in equation (2) to get the value of x,
-2x + 15 = 17
x = -1
The value of x is -1 and y is 3.
The additive inverse for the x coefficient in equation (2) is 2x.

Use the Pythagorean theorem to find b .
Answer:
b = 5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + b^2 = 13^2
144+b^2 =169
Subtract 144 from each side
144-144+b^2 = 169-144
b^2 = 25
Take the square root on each side
sqrt(b^2) = sqrt(25)
b = 5
Answer:
B= 5

A locker combination consists of two non-zero digits, and each combination consists of different digits. Event A is defined as choosing an even number as the first digit, and event B is defined as choosing an even number as the second digit. If a combination is picked at random, with each possible locker combination being equally likely, what is P(A and B) expressed in simplest form? A. 1/6 B. 5/18 C. 1/2 D. 5/9
Answer:
B. 5/18
Step-by-step explanation:
We have to digits taking the 0, they are as follows:
1, 2, 3, 4, 5, 6, 7, 8, 9
In other words, there are 9 in total.
Odd are 5 (1, 3, 5, 7, 9)
Pairs are 4 (2, 4, 6, 8)
Now, we have that the probability of drawing an odd one would be: 5/9
and that also, already selected that number, there would be 8 in total.
Therefore, drawing another number that is even the probability would be: 4/8
So the final probability is:
(5/9) * (4/8) = 20/72, we simplify (divide by 4) and we have 5/18 left
In other words, the answer is B. 5/18

Answer:
4, 5 and 27.
Step-by-step explanation:
There are 2 cube numbers between 0 and 36 .
They are 8 and 27.
36 - 27 = 9 so the other 2 numbers could be 4 and 5 because they are both factors of 20.
36 - 8 = 28 whose factors are 2 * 2 * 7 which are not factors of 20.

Step-by-step explanation:
i just answered it.
The value of the variable x will be 4. Then the correct option is B.
What is a quadrilateral?It is a polygon with four sides. The total interior angle is 360 degrees.
A quadrilateral with 90 degree angles.
If all the angles are right angle, then the quadrilateral should be either rectangle or square.
The lengths of the left and right sides are 10 and 2y + 4.
The lengths of the top and bottom sides are 18 and 10 + 2x.
If the adjacent side of the rectangle are same, then the rectangle will become square.
So, the quadrilateral is a rectangle.
Opposite sides of the rectangle are congruent.
Then the value of the variable x will be
10 + 2x = 18
2x = 18 – 10
2x = 8
x = 8 / 2
x = 4
The value of the variable x will be 4.
Then the correct option is B.

12 is 3/4 of what number
Answer:
Step by step: you need to divide the top and multiple by the bottom. 12 divided by 3 is 4, and 4 times 4 is 16
Answer:
16
Step-by-step explanation:
The formula to solve for this is [tex]\frac{is}{of}=\frac{percent}{100}[/tex]
Here the 12 is our "is", the "of" is the [tex]\frac{3}{4}[/tex] , and the "percent" is what we are solving for so we can replace it for "x"
So now replacing our values we have [tex]\frac{12}{\frac{3}{4} } =\frac{x}{100}[/tex]
Cross multiplying we get [tex](12)(100) = (x)(\frac{3}{4} )[/tex]
Which then simplifies to
Then multiplying both sides by 4 to get rid of the fraction we get 4800% = 3x
The we need to divide by 3 and we get 1600% = x
Now this is in a percentage, so we need to divide 1600 by 100 to turn it into a whole number which comes out to x = 16
Find the zeros of the function h(x)=x^2+23x+60 by factoring.
Answer:
x = - 20, x = - 3
Step-by-step explanation:
To find the zeros, let h(x) = 0, that is
x² + 23x + 60 = 0
Consider the factors of the constant term (+ 60) which sum to give the coefficient of the x- term (+ 23)
The factors are + 20 and + 3, since
20 × 3 = 60 and 20 + 3 = 23, thus
(x + 20)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 20 = 0 ⇒ x = - 20
x + 3 = 0 ⇒ x = - 3

How would you solve dy/dx = 4x - 2, y(-1) = 1 using differential equations?
Answer:
y=2(x square)-2x-3
Step-by-step explanation:
Let dy with y varibles in a hand
And dx with x variables on the other hand
dy=(4x-2)dx
Then by integration
y=2(square x)-2x+constant
Then substitute by x=-1 and y=1 to find the value of the constant
1=2(1)-2(-1)+ constant
Then constant=-3
Then the equation is
y=2(x square)-2x-3

What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round.
The exponential growth formula is:
Pn = Po × (1 + r)ⁿ⁻¹
Where:
Pn = the population at time n
Po = the population at time 0
r = the rate of growth
n = the number of years after time 0
In this case, Po = 26 million, n = 15 (2006 - 1991 = 15 years), and r can be calculated as follows:
Pn = 28 million
Po = 26 million
n = 15
r = (Pn - Po) / (Po × n)
r = (28 - 26) / (26 × 15)
r = 0.0077
Therefore, the population in 2006 can be calculated as follows:
P2006 = 26 × (1 + 0.0077)¹⁵
P2006 = 33.02 million
Therefore, the estimated population in 2006 was 33 million.

An octopus weighed 5 6 kilograms. After two weeks, its weight was increased by 3 10 kilograms. But afterward, it lost 1 5 kilograms in weight as it was sick. What is its current weight?
Answer:
The current weight of the octopus is:
[tex]w = \frac{14}{15}\,kg[/tex]
Step-by-step explanation:
The current weight is determine by addition and subtraction of rational numbers:
[tex]w = \frac{5}{6}\,kg + \frac{3}{10}\,kg -\frac{1}{5}\,kg[/tex]
[tex]w = \frac{50 + 18}{60}\,kg - \frac{1}{5}\,kg[/tex]
[tex]w = \frac{68}{60}\,kg - \frac{1}{5} \,kg[/tex]
[tex]w = \frac{17}{15}\,kg - \frac{1}{5}\,kg[/tex]
[tex]w = \frac{85-15}{75} \,kg[/tex]
[tex]w = \frac{70}{75}\,kg[/tex]
The current weight of the octopus is:
[tex]w = \frac{14}{15}\,kg[/tex]
