Determine the equation of the circle with center (0, -3) containing the point
(√32,-2).

Answer:

0.375 × a² × b³ × c⁵ ÷ x⁴ ÷ y³ ÷ z

Step-by-step explanation:

First, we can represent 3/8 in decimal form:

0.375

Next, we can show the numerator using multiplication:

0.375 × a² × b³ × c⁵

Then, we can individually divide by each factor in the denominator using the principle:

[tex]\dfrac{A}{B \times C} = A \div (B \times C) = A \div B \div C[/tex]

0.375 × a² × b³ × c⁵ ÷ x⁴ ÷ y³ ÷ z

The coordinates of the image of the triangle and the rules that can be used to transform the triangle are;

1. A' is located at (-3, 3)

B' is located at (-2, -1)

C' is located at (2, 1)

Second part; The rules are;

(x, y) → (x + 5, -y)

(x, y) → (5·x, 5·y)

A transformation of a figure is the reorientation of the figure to change the size and position of the figure.

1. The coordinates of the triangle ABC following the transformation (x, y) → (-x, y) are;

A(3, 3) (x, y) → (-x, y) A'(-3, 3)

B(2, -1) (x, y) → (-x, y) B'(-2, -1)

C(-2, 1) (x, y) → (-x, y) C'(2, 1)

2. The coordinates of the vertices of the triangle are; (1, 1), (4, 1), and (0, 4)

Translating the triangle five units right, we get;

(1 + 5, 1) = (6, 1), (4 + 5, 1) = (9, 1), and (0 + 5, 4) = (5, 4)

The coordinates of the triangle following a translation 5 units right are therefore;  (6, 1), (9, 1), and (5, 4)

The coordinates of the image of the point (x, y) following a reflection across the x-axis is the point (x, -y), therefore;'

The coordinates of the image of the triangle obtained from the previous transformation following a reflection across the x-axis is therefore;

(6, 1) reflection across the x-axis → (6, -1)

(9, 1) reflection across the x-axis → (9, -1)

(5, 4) reflection across the x-axis → (5, -4)

A rule that takes the triangle to a congruent triangle right five units and reflected over the x-axis is therefore;

The transformation of a triangle by a dilation by a scale factor of five, such that the triangle is five times larger can be obtained by the expression for a dilation transformation as follows;

The solution to the system of equations is p = 4 and q = 2

The substitution method is a way to solve a system of linear equations. In this method, we solve one of the equations for one of the variables, and then substitute the resulting expression into the other equation. This produces a new equation with one variable, which we can then solve for its value. Once we know the value of one variable, we can substitute it back into one of the original equations to find the value of the other variable.

To solve the system of equations using the method of substitution, we need to solve one of the equations for one of the variables, and then substitute the resulting expression into the other equation. We can start by solving the second equation for p:

p + 2q = 8

p = 8 - 2q

Now we can substitute this expression for p in the first equation:

2p - 3q = 2

2(8 - 2q) - 3q = 2

16 - 4q - 3q = 2

16 - 7q = 2

-7q = -14

q = 2

We can now substitute q = 2 into the expression we found for p:

p = 8 - 2q

p = 8 - 2(2)

p = 4

Therefore, the solution to the system of equations is p = 4 and q = 2.

After answering the presented question, we can conclude that it contains  inequality the extremes of Terri's data, which may not be representative of her typical time spent at the fitness club.

In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. Many simple inequalities can be solved by altering the two sides until just the variables remain. Yet, a lot of factors contribute to inequality: Negative values are divided or added on both sides. Exchange left and right.

The interquartile range is the most acceptable measure of variability for Terri's data (IQR).

The IQR is an acceptable measure of variability in this example because it focuses on the middle 50% of the data, which is where Terri spends the majority of her time at the fitness club. The mean and median are measures of central tendency rather than variability, and the range would be less useful in this situation because it contains the extremes of Terri's data, which may not be representative of her typical time spent at the fitness club.

Answer: B

Step-by-step explanation:

The answer is 9x^2 + 14xy -19y^2

Answer:

x = -4,

y = -1

Step-by-step explanation:

{-3x - 8y = 20,

{-5x + y = 19;

Make x or y the subject from either the 1st or the 2nd equation (I chose to make x the subject from the 2nd equation, because after division, the numbers can be written as a finite decimal fraction):

-5x = 19 - y / : (-5)

x = -3,8 + 0,2y

Replace x in the 1st equation with its value from the 2nd one (the underlined expression):

-3(-3,8 + 0,2y) - 8y = 20

Multiply every term inside the bracket by the term on the outside:

11,4 - 0,6y - 8y = 20

Collect like terms and add them together:

-8,6y = 20 - 11,4

-8,6y = 8,6 / : (-8,6)

y = -1

y = -1x = -3,8 + 0,2 × (-1) = -4

So, 100000+1X2 + 222+222+22222222222x111111111111111111111+222222222222222222 = 24,691,458,024,691,358,024,691,826

The probability of selecting a football card and then a basketball card is 0.16 or 16%. The probability of selecting a football card and then a basketball card can be calculated by multiplying the probability of selecting a football card on the first draw and the probability of selecting a basketball card on the second draw.

Since the first card is replaced before the second draw, the probability of selecting a football card or a basketball card remains the same on both draws.

The probability of selecting a football card on the first draw is 2/10, or 0.2, since there are 2 football cards in a total of 10 cards in the bag. The probability of selecting a basketball card on the second draw is 8/10, or 0.8, since there are 8 basketball cards left after the first draw.

Therefore, the probability of selecting a football card and then a basketball card can be calculated as follows:

P(Football and Basketball) = P(Football on 1st draw) x P(Basketball on 2nd draw)

= (2/10) x (8/10)

= 0.16

The condition that must be satisfied to use a chi-square goodness-of-fit test is D. The expected count for each category is at least 5.

A chi-square goodness-of-fit test is a statistical test used to determine whether the observed frequencies of categorical data match the expected frequencies. This test is often used to analyze categorical data, such as determining if the distribution of colors in a bag of candies matches the expected proportions.

The reason behind this condition is that the chi-square test is based on the assumption that the data follow a specific distribution. When the expected count for each category is less than 5, the test might not accurately represent the true distribution, and the results may be misleading. By having an expected count of at least 5 in each category, the test can better approximate the true distribution and provide more reliable results. Therefore, option D is correct.

Answer:

1) 24

2) 25

Step-by-step explanation:

Given:

2a + 3b = 8

4x + 10y = 50

.

1)

[tex] \frac{6a + 9b}{2a + 3b} = \frac{3(2a + 3b)}{2a + 3b} = 3[/tex]

Since the second expression is 3 times greater then the previous one, the product will also be 3 times greater:

6a + 9b = 3 × 8 = 24

.

2)

[tex] \frac{2x + 5y}{4x + 10y} = \frac{2x + 5y}{2(2x + 5y)} = \frac{1}{2} = 0.5[/tex]

The second expression's value is two times smaller than the first one's, so the product will also be two times smaller:

2x + 5y = 0,5 × 50 = 25

Answer:

[tex]y - ( - 20) = 9(x - ( - 2))[/tex]

[tex]y + 20 = 9(x + 2)[/tex]

Step-by-step explanation:

[tex]m = \frac{79 - ( - 20)}{9 - ( - 2)} = \frac{99}{11} = 9[/tex]

[tex]y - ( - 20) = 9(x - ( - 2))[/tex]

[tex]y + 20 = 9(x + 2)[/tex]

The probability that the mean battery life would be greater than 1173.8 minutes is 0.9588

We can solve this problem using the central limit theorem, which tells us that the distribution of sample means from a population with a known variance becomes approximately normal as the sample size increases.

The standard error of the mean can be calculated as

SE = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size

Here, we are given that the population variance is 8100, so the population standard deviation is the square root of 8100, which is 90.

SE = 90 / sqrt(72) = 10.6066

Next, we need to standardize the sample mean using the z-score formula

z = (X - μ) / SE

where X is the sample mean, μ is the population mean.

Here, the population mean is given as 1192 minutes and the sample mean we are interested in is 1173.8 minutes.

z = (1173.8 - 1192) / 10.6066 = -1.7356

We want to find the probability that the sample mean is greater than 1173.8 minutes. Since we have a negative z-score, we need to find the area to the right of this value on a standard normal distribution. We can use a z-table or a calculator to find this probability.

Using a standard normal distribution table, we find that the area to the right of z = -1.7356 is 0.9588.
