Answer:

A pound of jelly beans costs $4, and a pound of gummy worms costs $6

Step-by-step explanation:

Let

Cost of one pound of Jelly beans = x

Cost of one pound of Gummy worms = y

Making equations from the statements:

Lillian bought 4 pounds of jelly beans and 3 pounds of gummy worms for $34: \(4x+3y=34\)

Kelsey bought 5 pounds of jelly beans and 3 pounds of gummy worms for $38: \(5x+3y=38\)

Solving both equations we can found cost of candies.

Let:

\(4x+3y=34--eq(1)\\5x+3y=38--eq(2)\)

Subtracting both equations to find value of x

\(4x+3y=34\\5x+3y=38\\- \ \ \ - \ \ \ \ -\\------\\-x=-4\\x=4\)

So,we get value of x=4

Now putting value of x in eq(1) to find value of y

\(4x+3y=34\\4(4)+3y=34\\16+3y=34\\3y=34-16\\3y=18\\y=18/3\\y=6\)

We get value of y=6

Cost of one pound of Jelly beans = x = 4

Cost of one pound of Gummy worms = y = 6

A pound of jelly beans costs $4, and a pound of gummy worms costs $6

When a polynomial function f is divided by x-c, the remainder is given by the value of the polynomial function f evaluated at the value c. This result is known as the Remainder Theorem.

The result of dividing a polynomial function f(x) by x-c equals f(c), according to the theorem. Numerous branches of mathematics, such as algebra, calculus, and number theory, can benefit from this theorem.

It offers a straightforward and effective technique for computing remainders and comprehending how polynomial functions behave. The Remainder Theorem can be used to factor polynomials, factor complicated calculations, and solve equations with polynomial functions.

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the formula for calculating probability

STEP 2: Find the probability of landing on a number greater than 5

STEP 3: Find the probability of landing on a number

Answer:

The answer is 84.

Step-by-step explanation:

The given equation is

4x*2 + 2x -5 = 0

Here a= 4, b= 2, c= -5

Since Discriminant= b*2 -4ac

Putting values

Discriminant= (2)*2 - 4(4)(-5)

= 4 + 80

= 84

Since our Discriminant(84) is >0 and is not a perfect square so the roots of the given equation are unequal and irrational(real).

Yes, there is evidence to suggest that the sex of individuals and their online book purchasing habits are associated.

Null Hypothesis (H0): The sex of individuals and their online book purchasing habits are independent.

Alternative Hypothesis (HA): The sex of individuals and their online book purchasing habits are associated.

We will calculate the expected frequencies assuming independence:

Expected frequency for men who purchased books online:

= (227/427) * (46 + 35)

= 78.34.

Expected frequency for men who did not purchase books online:

= (227/427) * (227 - 46 + 200 - 35)

= 148.66

Expected frequency for women who purchased books online:

= (200/427) * (46 + 35)

= 41.66

Expected frequency for women who did not purchase books online:

= (200/427) * (227 - 46 + 200 - 35)

= 108.34

Chi-square = \([(observed - expected)^2 / expected]\)

The observed frequencies are:

chi-square = \([(46 - 78.34)^2 / 78.34] + [(181 - 148.66)^2 / 148.66] + [(35 - 41.66)^2 / 41.66] + [(165 - 108.34)^2 / 108.34]\)

chi-square = 5.887

df = (2 - 1) * (2 - 1) = 1

Using a significance level of 0.05, the critical value of chi-square for df = 1 is 3.841.

Since the calculated chi-square value (5.887) is greater than the critical value (3.841), we reject the null hypothesis. Therefore, there is evidence to suggest that the sex of individuals and their online book purchasing habits are associated.

Full question:

A survey of 427 randomly chosen adults finds that 46 of 227 men and 35 of 200 women had purchased books online. Is there evidence that the sex of the person and whether they buy books online are​ associated?

Answer:

$140,000

Step-by-step explanation:

Paso 1

Si a una persona le deben 7/9 de $ 450,000

La cantidad que se le debe a la persona se calcula como:

7/9 × $ 450,000

= $ 350,000

Paso 2

Solo se cancela 3/5 de esa deuda.

El monto de la deuda que se cancela se calcula como:

3/5 × $ 350,000

= $ 210,000

Paso 3

Por lo tanto, la cantidad de dinero que debe se calcula como:

$ 350,000 - $ 210,000

= $ 140,000

Answer:

Step-by-step explanation:

Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4

Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4

Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8

Quotient: 6*10^-4/1.5 * 10^-4 = 4

Notice the answers, because they give you the rules.

When adding exponents and rationales, if the powers are the same then the rationales merely add.

Same rule applies to subtraction. Retain the powers and subtract the rationales.

When multiplying the rationales multiply, but the rationales add. they don't stay the same.

When dividing, the rationales divide and the powers subtract -- numerator minus denominator

Answer:

C. right angle

Step-by-step explanation:

I will upload an image of a right angle that perfectly fits the question:

The angles that measure 90° are called right angles, so the correct option is C.

A 90° angle is the one we get when two perpendicular lines intersect (we actually get four of these).

And are the same ones that we can see on squares or rectangles, where the connecting sides are perpendicular between them.

The name of that type of angle, as one could imagine, is Right Angle (for the nature of the intersection that conforms them). So the correct option is C.

Answer: Male population = 26,000

               Female population = 24,000

Step-by-step explanation: Male population = X

                                             Female population = Y

               x+y=50,000

               y=50,000-x-(1st equation)

Again (x+x X 5%) + (y+y X 3%) = 52,020

-> x+5x/100 + y+3y/100 = 52020

->  100x+5x+100y+3y =52020

   ________________

                100

-> 105x+103y = 52020-( 2nd Equation)

Putting Eq 1 into 2 ,

105x+103 ( 50,000-x)= 52,020

-> 105x + 5,150,000-103x = 52,020

->2x = 52,020-5,150,000

->2x = 52,000

    x = 26,000 (Male population)

    y = 50,000-26,000

       = 24,000 (Female population)

An equilateral triangle is a type of triangles which can always be used as a counterexample to the statement ""all angles in a triangle are acute"".

What is acute angle?

An acute angle is one that is smaller than 90 degrees in length. If the arms of an angle open up less than a "L," an acute angle is created because a "L" shape forms at 90°.

What are obtuse angle?

Angle between 90 to 180 are known as obtuse angle.

Because an equilateral triangle is likewise equiangular, it can be used as a counterexample. So, each angle has a 360/3=60 measurement. Two angles are therefore acute angle , and the third's measure is also acute.

The equation of the line that passes through (-5,3) and (1,1) is y = (-1/3)x + 3.

To find the equation of the line that passes through the given points, we need to use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept.

First, we need to find the slope of the line. The slope formula is:

m = (y₂ - y₁) / (x₂ - x₁)

Plugging in the given points, we get:

m = (1 - 3) / (1 - (-5))
m = (-2) / (6)
m = -1/3

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line. The point-slope form is:

y - y₁ = m(x - x₁)

Plugging in the slope and one of the given points, we get:

y - 3 = (-1/3)(x - (-5))
y - 3 = (-1/3)(x + 5)
y - 3 = (-1/3)x - (5/3)
y = (-1/3)x + (9/3)
y = (-1/3)x + 3

By combining the approaches, researchers can gather comprehensive data, analyze existing information, conduct controlled experiments, and obtain direct responses through surveys.

Existing Data Analysis: Begin by collecting relevant existing data from reliable sources, such as research studies, government databases, or publicly available datasets. Identify variables related to the research question and extract the necessary data for analysis. Use statistical tools and techniques to examine the relationship between the IV and DV based on the existing data.

Experimentation: Design and conduct experiments to measure the IV and its impact on the DV. Clearly define the experimental conditions and variables, including the manipulation of the IV and the measurement of the resulting changes in the DV. Ensure appropriate control groups and randomization to minimize biases and confounding factors.

Survey Research: Develop a survey questionnaire to gather data directly from participants. Formulate specific questions that capture the IV and DV variables. Include options or response choices that cover a range of possibilities for the IV and capture the variations in the DV. Ensure the survey questions are clear, unbiased, and appropriately structured to elicit relevant responses.
