Chance is simply how probable an event is to happen. If we are unsure of how an incident will come out, we might debate the probability of various outcomes, and how likely they are. The examination of occurrences regulated by probability is termed statistics.

The p-value is not less than the significance level, Ramon fails to reject the null hypothesis.

What is null hypothesis?

In statistical hypothesis testing, the null hypothesis is a statement that there is no significant difference between two specified populations, or that a proposed relationship between two variables does not exist.

Ramon used the following null and alternative hypotheses:

H0: p = 0.30 (The proportion of blue jelly beans is 30%)

Ha: p > 0.30 (The proportion of blue jelly beans is greater than 30%)

Ramon calculated a p-value of 0.256, which is greater than his significance level of 0.1.

Since the p-value is not less than the significance level, Ramon fails to reject the null hypothesis.

Therefore, he does not have enough evidence to conclude that the proportion of blue jelly beans is greater than 30%.

Step-by-step explanation:

The y-intercept of the function is -1. (option a).

In mathematics, a function is a rule that assigns each input (or argument) of a set, to a unique output (or value) of another set. In this case, the function f(x) is given by f(x)=−1(2/3)^x.

To find the y-intercept of a function, we need to evaluate the function at x=0. This is because the y-intercept is the point at which the graph of the function intersects the y-axis, and the y-axis is where x=0.

To find the y-intercept of the function f(x)=−1(2/3)ˣ, we need to evaluate the function at x=0. This gives us:

f(0) = -1(2/3)⁰

f(0) = -1(1)

f(0) = -1

This means that the graph of the function intersects the y-axis at the point (0,-1).

Hence the correct option is (a).

Step-by-step explanation:

The probability that the mean length of 48 items is greater than 8.8 inches can be calculated using the normal distribution.

First, we need to standardize the value 8.8 inches by subtracting the mean length (10.2 inches) and dividing by the standard deviation (3.3 inches):

(8.8 - 10.2) / 3.3 = -1.4 / 3.3 = -0.42424242

We can use a z-table or a normal distribution calculator to find the probability that a random variable is less than -0.42424242 standard deviations below the mean. This probability is equal to the probability that the mean length of 48 items is greater than 8.8 inches.

Using a calculator, we find that the probability is 0.3389.

Rounding to four decimal places, the probability that the mean length of 48 items is greater than 8.8 inches is 0.3389.

Answer:

y = -8x+19

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -8x+b

Substitute the point into the equation

3 = -8(2)+b

3 = -16+b

Add 16 to each side

3+16 = b

19 = b

y = -8x+19

Step-by-step explanation:

to find the equation of this line you use the equation of the slope intercept which is y-y1= m (x-x1)

y-3=-8(x-2)

y-3=-8x+16

y=-8x+16+3

y=-8x+19

The concept of isosceles triangle is presented in this answer.

An isosceles triangle is a type of triangle in which two sides are of equal length. These two sides are known as the legs of the triangle, and the third side is called the base. The angles opposite to the legs are also equal in measure. This makes the isosceles triangle a symmetrical shape, with two congruent sides and angles.

In an isosceles triangle, the height is perpendicular to the base and bisects it, dividing the base into two equal parts. The height is also an axis of symmetry of the triangle, which means that if the triangle is folded along the height, the two halves will be congruent.

The problem is incomplete, hence concepts of isosceles triangles are presentd.

On solving the provided question, we can say that -  here in graph we have on solving equation  \(2x^2+ 9y^2 \\\) = \(8 + 9 = 17\)

An equation is a formula in mathematics that joins two statements with the equal symbol = to represent equality. The definition of an equation in algebra is a mathematical statement proving the equality of two mathematical expressions. In the equation 3x + 5 = 14, for instance, the terms 3x + 5 and 14 are separated by an equal sign. The link between two phrases on either side of a letter is expressed mathematically. There is often only one variable, which is also the symbol. instance: 2x - 4 Equals 2.

The axis of symmetry of the given quadratic function f(x) = -(x - 2)(x + 4) is x = -1.

Given the function in the question:

f(x) = -(x - 2)(x + 4)

To find the axis of symmetry, first expand  quadratic function f(x) = -(x - 2)(x + 4).

f(x) = -(x - 2)(x + 4)

f(x) = (-x + 2)(x + 4)

f(x) = -x(x + 4) + 2( x + 4 )

f(x) = -x² - 4x + 2x + 8

Collect and add like terms

f(x) = -x² - 2x + 8

To find the axis of symmetry, we can use the formula:

x = -b/2a

Where a = -1 and b = -2.

Substituting these values, we get:

x = -(-2) / 2(-1)

Simplify

x = 2 / -2

x = -1

Therefore, the the axis of symmetry is x = -1.

Total relative frequency

Pets         Men     Women   Total

Dogs         20%     30%       50%

Cats           13.8%    20.8%     34.6%

Birds           6.2%    9.2%     15.4%

Total             40%     60%     100%

Percentage is the ratio of an amount out of a total amount. The sign that represents percentage is %. In order to convert a value to a percentage, multiply the value by 100.

Relative frequency measures how often a value appears relative to the sum of the total values.

Relative frequency of men that have dogs = (26/130) x 100 = 20%

Relative frequency of women that have dogs = (39/130) x 100 = 30%

Relative frequency of those that have dogs = 20% + 30% = 50%

Relative frequency of men that have cats = (18/130) x 100 = 13.8%

Relative frequency of women that have cats = (27/130) x 100 = 20.8%

Relative frequency of those that have cats = (45/130) x 100 = 34.6%

Relative frequency of men that have birds = (8/130) x 100 = 6.2%

Relative frequency of women that have birds = (12/130) x 100 = 9.2%

Relative frequency of those that have birds = 6.2% + 9.2% = 15.4%

Relative frequency of males = (52/130) x 100 = 40%
