Answer:
156/100=n/70
Step-by-step explanation:
1.56/70=109.2
156/100=1.56
109.2/70=1.56
as far as im concerned 1.56 and 1.56 is equal lol
The true property is (156/100) = (n/70).
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that n is equal to 156% of 70
n=156% of 70
n=156% × 70
n= (156/100) × 70
(n/70) = (156/100)
Or, (156/100) = (n/70)
Hence, the true property is (156/100) = (n/70).

Step-by-step explanation:
A jar contains red marbles and 10 blue marbles. If you take a random sample of two marbles from this jar, then the probability that the second marble is blue exactly equal to the probability that the first marble is blue if sampling with replacement is used. In sampling with replacement, you would return the first marble obtained to the jar. True/false
Since the probability of drawing a blue marble in the first draw and the probability of drawing a blue marble in the second draw are the same, the statement is true.
The probability of drawing a blue marble in the first draw is:
P(First marble is blue) = (number of blue marbles) / (total number of marbles)
P(First marble is blue) = 10 / (10 + number of red marbles)
Now, if we draw with replacement, we return the first marble to the jar before drawing the second one. Therefore, the number of blue marbles and the total number of marbles in the jar remains the same. Therefore, the probability of drawing a blue marble in the second draw is also:
P(Second marble is blue) = (number of blue marbles) / (total number of marbles)
P(Second marble is blue) = 10 / (10 + number of red marbles)
Since the probability of drawing a blue marble in the first draw and the probability of drawing a blue marble in the second draw are the same, the statement is true.
Therefore, the answer is True.

Isabella has $61,000 in a savings account. The interest rate is 14
% per year and is not compounded. How much will she have in
total in 4 years?
Use the formula i = prt, where i is the interest earned, p is the
principal (starting amount), r is the interest rate expressed as a
decimal, and it is the time in years.
Answer:
$95,160
Step-by-step explanation:
Simple Interest Formula
I = Prt
where:
I = total interest accrued.P = principal.r = interest rate (in decimal form).t = time (in years).Given values:
P = $61,000r = 14% = 0.14t = 4 yearsSubstitute the given values into the formula to calculate how much interest the account accrued in 4 years:
\(\implies \sf I=61000 \cdot 0.14 \cdot 4\)
\(\implies \sf I=8540 \cdot 4\)
\(\implies \sf I=34160\)
Therefore, the account accrued $34,160 of interest in 4 years.
To find how much Isabella will have in total after 4 years, add the principal to the interest:
\(\implies \sf A=61000+34160\)
\(\implies \sf A=95160\)
Therefore, Isabella will have a total of $95,160 in 4 years.

question 9 the black-footed ferret was declared extinct in 1979, but a small population of the animals was found in wyoming in 1981. some of the wild ferrets were captured and bred in captivity. the animals bred in captivity were then reintroduced into the wild. suppose 131 ferrets are found in a wild population in the first year. in the next year, there are 196 ferrets in the same population. calculate the growth rate from the first year to the second year: a.65.0% b.66.8% c.33.1% d.85.1% e.49.6%
The growth rate from the first year to the second year will be option : c) 33.1%
We need to calculation of the growth rate from the first year to the second year, since we know that there are 146 ferrets are found in a population in the first year. In the next year, there are 183 ferrets in the same population, so therefore, we can now calculate the growth rate, the growth rate is = (183 - 146)/146 = 33.1%
We need to basically take the difference of the population and then we have to divided it by the first-year population so that the growth rate could come as the solution.

Suppose that A and B are points on the number line.
If AB=9 and A lies at 7, where could B be located?
If there is more than one location, separate them with commas.
On the number line, if 'A' lies at 7 then 'B' could lie at -2, 16.
What is a number line?
A number line can be stretched in either direction indefinitely and is commonly displayed horizontally.
The numerals on the number line grow as one goes from left to right and drop as one moves from right to left.
Given, AB = 9 and 'A' lies at 7
So, basically 'B' can be at -2 on the number line which makes the distance between 'A' and 'B' 9 units. The same is possible for B at 16 on the number line.

+5xy)

V
What are the magnitude and direction of electric field at a point (3.0 m,2.0 m) ?
The direction of the electric field can be determined by taking the negative gradient of the electric potential function. At the point (3.0 m, 2.0 m), the electric field is directed in the positive x-direction.
To find the electric field at a given point, we can take the negative gradient of the electric potential function. The electric potential function V(x, y) is given as V = 2.0x^2 - 3.0y^2 + 5xy.
Taking the partial derivatives with respect to x and y, we obtain:
dV/dx = 4.0x + 5y
dV/dy = -6.0y + 5x
At the point (3.0 m, 2.0 m), we substitute x = 3.0 and y = 2.0 into the partial derivatives:
dV/dx = 4.0(3.0) + 5(2.0) = 22.0
dV/dy = -6.0(2.0) + 5(3.0) = 1.0
The electric field E is given by E = -∇V, where ∇ is the gradient operator. Therefore, the electric field at (3.0 m, 2.0 m) is E = (-22.0 i + 1.0 j) N/C.
To find the magnitude of the electric field, we calculate:
|E| = sqrt((-22.0)^2 + (1.0)^2) ≈ 60.1 N/C.
The magnitude of the electric field is approximately 60.1 N/C, and its direction is in the positive x-direction.

The median of a set of data, we need to arrange the values in ascending order and then determine the middle value. If there are an odd number of values, the median is the middle value. If there are an even number of values, the median is the average of the two middle values.
Let's rearrange the given data in ascending order:
1, 1¾, 2, 3, 5¼, 7/2
To simplify the fractions, we can convert them to decimals:
1, 1.75, 2, 3, 5.25, 3.5
Now, we can see that there are six values in total, which is an even number. Therefore, the median will be the average of the two middle values.
The two middle values are 2 and 3, so the median can be calculated as:
Median = (2 + 3) / 2
Median = 5 / 2
Median = 2.5

Let R be the region in the fourth quadrant enclosed by the x-axisand the curve Y = X^2 - 2KX, where k > 0. if the area of the region R is 36, thenthe value of k is
(A) 2
(B) 3
(C) 4
(D) 6
(E) 9
We want to find the value of k given that the area of the region R is 36. To do this, we need to find the limits of integration and set up the integral for finding the area of the region R. The answer is (B) 3.
Since R is in the fourth quadrant and is enclosed by the x-axis and the curve Y = X^2 - 2KX, we can find the limits of integration by setting Y = 0 and solving for X:
0 = X^2 - 2KX
X(X - 2K) = 0
X = 0 or X = 2K
So the limits of integration are from X = 0 to X = 2K.
Now we can set up the integral for finding the area of the region R:
∫[0,2K] (X^2 - 2KX) dX
Integrating this expression gives:
[(1/3)X^3 - KX^2] evaluated at 0 and 2K
Plugging in the limits of integration and simplifying, we get:
(8/3)K^3 - 4K^3
Simplifying this expression, we get:
(2/3)K^3 = 36
Solving for K, we get:
K^3 = 54
Taking the cube root of both sides, we get:
K = 3
Therefore, the answer is (B) 3.
To find the value of k, follow these steps:
1. Determine the x-intercepts of the curve Y = X^2 - 2KX by setting Y = 0.
0 = X^2 - 2KX
X(X - 2K) = 0
The x-intercepts are X = 0 and X = 2K.
2. As we are looking for the area in the fourth quadrant, the integral bounds are from 0 to 2K.
3. Set up the integral for the area:
Area = ∫(X^2 - 2KX) dx, from 0 to 2K
4. Evaluate the integral:
Area = (X^3/3 - KX^2) | from 0 to 2K
= [(8K^3/3 - 4K^3) - (0)]
= 8K^3/3 - 4K^3
= (4K^3/3)
5. Set the area equal to 36 and solve for k:
36 = (4K^3/3)
9 = K^3
k = 3^(1/3) ≈ 2.08
The closest value from the given options is (A) 2.
