The easiest way to answer this is to plug in all of the given choices to see which of them will satisfy the given equation.

We get,

Choice A: 7

Therefore, x is not equal to 7.

Choice B: 3

Therefore, x is not equal to 3.

Choice C: -2

Therefore, x is not equal to -2.

Choice D: -7

Therefore, x = -7

The answer is letter D : -7

Answer:

x = -1, y = 2

Step-by-step explanation:

6x + 5y = 4

6x - 7y = -20

We already have a similar leading coefficient (6 for X), so we just subtract equation 1 from equation 2 to get:

12y = 24

Now solve normally:

y = 2

Then substitute into the first equation (or second, it doesn't matter)

6x + 10 = 4

6x = -6

x = -1

We follow the inclusive rule, The answer to the question is (A) that is

In mathematics, an interval is expressed in numerical terms. All the numbers between two specific integers are referred to as an interval. All actual values between those two are included in this range. Any form of number you may imagine is a real number.

The intervals used are:

(a , b) , All the numbers between a & b without including them.

[a, b] , All the numbers between a & b including them.

y lies in [10,50].

And since it means that it includes 10 and 50 and all the numbers between them.

The final answer is (A) that is if y>1=10 and y <=50.

The standard form of the equation of the parabola with a focus of (4, -3), and a directrix of x = 0 is; (y + 3)² = 8·(x - 2)

The equation of a parabola with a focus (4, -3) and a directrix of x = 0, can be found using the definition of the curve of a parabola, which is a curve that describes the location of a point that is equidistant from the focus and the directrix.

Let (x, y) represent the coordinate of the point, therefore;

The distance of the point from the point to the focus is therefore;

Distance = √((x - 4)² + (y + 3)²)

The distance from between the point and the directrix = |x|

According to the definition of the locus of a parabola, therefore;

√((x - 4)² + (y + 3)²) = |x|

(x - 4)² + (y + 3)² = x²

x² + y² - 8·x + 6·y + 25 = x²

x² - x² + y² - 8·x + 6·y + 25 = 0

y² - 8·x + 6·y + 25 = 0

y² + 6·y + 25 = 8·x

However, we get; Directrix, x = h - p

focus = (h + p, k)

Therefore;

h + p = 4

k = -3

h - p = 0

2·h = 4 + 0 = 4

h = 4/2 = 2

h = 2

p = 4 - 2 = 2

p = 2

The equation of a parabola is; (y - k)² = 4·p·(x - h)

The equation of the parabola is; (y - (-3))² = 4 × 2 × (x - 2)

The standard form of the equation is therefore;

(y + 3)² = 8·(x - 2)

Independent

Step-by-step explanation:

From the word independent, which means being able ot stand alone, that is the absence or presence of one has no impact on the outcome of each phenomenon. Two events A and B are said to be independent, if the occurence of one has no bearing on the probability or chance that B will occur. This means that each event occurs without reliance on the occurence of the other. This is different from mutually exclusive event whereby event A has direct bearing in the probability of the occurence of event B.

Answer:

Step-by-step explanation:

Answer:

We have point P(-3,-6).

Step-by-step explanation:

We want to find a point P(x,y).

Since it is on the directed line segment AB in the ratio 3:4, it means that:

\(P - A = \frac{3}{3+4}(B - A)\)

So

\(P - A = \frac{3}{7}(B-A)\)

We apply this to both the x-coordinate and y-coordinate of P.

x-coordinate:

x-coordinate of A: -9

x-coordinate of B: 5

x-coordinate of P: x

So

\(P - A = \frac{3}{7}(B-A)\)

\(x - (-9) = \frac{3}{7}(5-(-9))\)

\(x + 9 = \frac{3}{7} \times 14\)

\(x + 9 = 6\)

\(x = -3\)

y-coordinate:

y-coordinate of A: -9

y-coordinate of B: -2

y-coordinate of P: y

So

\(P - A = \frac{3}{7}(B-A)\)

\(y - (-9) = \frac{3}{7}(-2-(-9))\)

\(y + 9 = \frac{3}{7} \times 7\)

\(y + 9 = 3\)

\(y = -6\)

We have point P(-3,-6).

The percentage improvement in reliability when test length is doubled is 15%

R(n) = 0.25n / (0.75 + 0.25n)

substitute n = 1 into the equation :

R(n) = 0.25n / (0.75 + 0.25n)

R(1) = 0.25(1) / (0.75 + 0.25(1))

R(1) = 0.25 / 1

R(1) = 0.25

when test length is doubled , n = 2

substitute n = 1 into the equation :

R(n) = 0.25n / (0.75 + 0.25n)

R(2) = 0.25(2) / (0.75 + 0.25(2))

R(2) = 0.5 / 1.25

R(2) = 0.4

Percentage improvement can be calculated thus ;

R(2)-R(1)/R(1) × 100%

The population in 2008 is approximately 138 million.

To solve it, we will use the exponential growth formula:

P(t) = P0 *\(e^(rt)\)

where

P(t) = population at time t

P0 = initial population (127 million)

e = natural logarithm base (approximately 2.71828)

r = rate of growth

t = number of years

To find the rate of growth, we can use the population in 2000 as a reference point.

P(7) = 132 million = P0 * \(e^(7r)\)

Divide both sides by P0:

132 million / 127 million = \(e^(7r)\)

Take the natural logarithm of both sides:

ln (132 million / 127 million) = 7r

Solve for r:

r = ln (132 million / 127 million) / 7

Now that we have the rate of growth, we can use it to estimate the population in 2008:

P(15) = 127 million * \(e^(15r)\)

Plug in the value of r:

P(15) = 127 million * \(e^(15 * ln (132 million / 127 million) / 7)\)

Using a calculator, the population in 2008 is approximately 138 million.

Round to the nearest million: 138 million.

Answer:

Step-by-step explanation:

For the first bag:

Price of the bag = $12

Number of balls in the bag = 15

Price per ball = Price of the bag / Number of balls

Price per ball for the first bag = $12 / 15 = $0.8

For the second bag:

Price of the bag = $15

Number of balls in the bag = 20

Price per ball = Price of the bag / Number of balls

Price per ball for the second bag = $15 / 20 = $0.75

Comparing the prices per ball, we find that the second bag has a lower price per baseball. Therefore, the second bag offers a better price for individual baseballs compared to the first bag.

Answer:

Step-by-step explanation:

To find out which bag prices individual baseballs lower, we can divide the total cost of each bag by the number of balls in the bag. This will give us the price per ball for each bag.

For the first bag, the price per ball is $12 / 15 = $0.80.

For the second bag, the price per ball is $15 / 20 = $0.75.

Therefore, the second bag prices individual baseballs lower.

Answer:

\(|\frac{x}{y} |\)

Step-by-step explanation:

We are given the following expression: \(\sqrt\frac{x^3y^5}{xy^7}\), where x > 0 and y > 0.

We want to simplify it.

To do that, we can first simplify what is under the radical, then take the square root of what is left.

Recall that when simplifying exponents, we don't want any negative or non-integer radicals left.

To simplify what is under the radical, we can remember the rule where \(\frac{a^n}{a^m} = a^{n-m}\).

So, that means that \(\frac{x^3}{x} = x^2\) and \(\frac{y^5}{y^7} = y^{-2}\) .

Under the radical, we now have:

\(\sqrt{x^2y^{-2}}\)

Now, we take the square root of both exponents to get:

\(|xy^{-1}|\)

The reason why we need the absolute value signs is because we know that x > 0 and y > 0, but when we take the square root of of \(x^2\) and \(y^{-2}\) , the values of x and y can be either positive or negative, so by taking the absolute value, we ensure that the value is positive.

However, we aren't done yet; remember that we don't want any radicals to be negative, and the integer of y is negative.

Recall that if \(a^{-n}\), that is equal to \(\frac{1}{a^n}\).

So, by using that,

\(|x * \frac{1}{y} |\)

This can be simplified to:

\(|\frac{x}{y} |\)

Answer:

Step-by-step explanation:

The sampling distribution of the sample mean for samples of size n is approximately normal with mean μ and standard deviation σ/sqrt(n), where μ is the mean of the population, σ is the standard deviation of the population, and sqrt(n) is the square root of the sample size.

In this case, the population mean is μ = 112 and the population standard deviation is σ = 22. We are interested in the sampling distribution of the sample mean for samples of size n = 16.

The mean of the sampling distribution of the sample mean is the same as the population mean, which is μ = 112.

The standard deviation of the sampling distribution of the sample mean is σ/sqrt(n) = 22/sqrt(16) = 5.5.

Therefore, the sampling distribution of the sample mean for samples of size 16 is approximately normal with mean 112 and standard deviation 5.5.
