Step-by-step explanation:

Write the equation of the line in the slope-intercept form:

1. The slope of the line is

[tex]\dfrac{-65-(-52)}{51-34}=-\dfrac{13}{17}[/tex]

2. The equation of the line is

[tex]y-(-52)=-\dfrac{13}{17}(x-34)\\ \\y+52=-\dfrac{13}{17}x+26\\ \\y=-\dfrac{13}{17}x-26[/tex]

Now, find the y-intercept, substitute x = 0:

[tex]y=-\dfrac{13}{17}\cdot 0-26\\ \\y=-26[/tex]

Answer:

Mutually exclusive,

[tex]P(\text{Lemon-lime or orange})=\frac{2}{3}[/tex]

Step-by-step explanation:

Please consider the complete question:

Determine if the scenario involves mutually exclusive or overlapping events. Then find the  probability.

A cooler contains twelve bottles of sports  drink: four lemon-lime flavored, four  orange flavored, and four fruit-punch  flavored. You randomly grab a bottle. It  is a lemon-lime or an orange.

Let us find probability of finding one lemon lime drink.

[tex]P(\text{Lemon-lime})=\frac{\text{Number of lemon lime drinks}}{\text{Total drinks}}[/tex]

[tex]P(\text{Lemon-lime})=\frac{4}{12}[/tex]

[tex]P(\text{Lemon-lime})=\frac{1}{3}[/tex]

Let us find probability of finding one orange drink.

[tex]P(\text{Orange})=\frac{\text{Number of orange drinks}}{\text{Total drinks}}[/tex]

[tex]P(\text{Orange})=\frac{4}{12}[/tex]

[tex]P(\text{Orange})=\frac{1}{3}[/tex]

Since probability of choosing a lemon lime doesn't effect probability of choosing orange drink, therefore, both events are mutually exclusive.

We know that probability of two mutually exclusive events is equal to the sum of both probabilities.

[tex]P(\text{Lemon-lime or orange})=P(\text{Lemon-lime})+P(\text{Orange})[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{1}{3}+\frac{1}{3}[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{1+1}{3}[/tex]

[tex]P(\text{Lemon-lime or orange})=\frac{2}{3}[/tex]

Therefore, the probability of choosing a lemon lime or orange is [tex]\frac{2}{3}[/tex].

Answer:

[tex]y=\frac{11}{5}[/tex]

Step-by-step explanation:

Given expression

[tex]\frac{1}{3}(y-2)-\frac{5}{6}(y+1)=\frac{3}{4}(y-3)-2[/tex]

To solve for [tex]y[/tex] for the given expression.

Solution:

We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.

The multiples of the denominators are:

3 = 3,6,9,12,15

6 = 6,12

4 = 4,8,12

The least common multiple = 12.

Multiplying each term with 12.

[tex]12.\frac{1}{3}(y-2)-12.\frac{5}{6}(y+1)=12.\frac{3}{4}(y-3)-2(12)[/tex]

[tex]4(y-2)-10(y+1)=9(y-3)-24[/tex]

Using distribution.

[tex]4y-8-10y-10=9y-27-24[/tex]

Simplifying.

[tex]-6y-18=9y-51[/tex]

Adding [tex]6y[/tex] both sides.

[tex]-6y+6y-18=9y+6y-51[/tex]

[tex]-18=15y-51[/tex]

Adding 51 both sides.

[tex]-18+51=15y-51+51[/tex]

[tex]33=15y[/tex]

Dividing both sides by 15.

[tex]\frac{33}{15}=\frac{15y}{15}[/tex]

[tex]\frac{33}{15}=y[/tex]

Simplifying fractions.

[tex]\frac{11}{5}=y[/tex]

∴ [tex]y=\frac{11}{5}[/tex]  (Answer)

When 6 is subtracted from the square of a number, the result is 5 times the number, then the negative solution is -1

Given that when 6 is subtracted from the square of a number, the result is 5 times the number

To find: negative solution

Let "a" be the unknown number

Let us analyse the given sentence

square of a number = [tex]a^2[/tex]

6 is subtracted from the square of a number = [tex]a^2 - 6[/tex]

5 times the number = [tex]5 \times a[/tex]

So we can frame a equation as:

6 is subtracted from the square of a number = 5 times the number

[tex]a^2 - 6 = 5 \times a\\\\a^2 -6 -5a = 0\\\\a^2 -5a -6 = 0[/tex]

Let us solve the above quadratic equation

For a quadratic equation [tex]ax^2 + bx + c = 0[/tex] where [tex]a \neq 0[/tex]

[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

Here in this problem,

[tex]a^2-5 a-6=0 \text { we have } a=1 \text { and } b=-5 \text { and } c=-6[/tex]

Substituting the values in above quadratic formula, we get

[tex]\begin{array}{l}{a=\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(-6)}}{2 \times 1}} \\\\ {a=\frac{5 \pm \sqrt{25+16}}{2}=\frac{5 \pm \sqrt{49}}{2}} \\\\ {a=\frac{5 \pm 7}{2}}\end{array}[/tex]

We have two solutions for "a"

[tex]\begin{array}{l}{a=\frac{5+7}{2} \text { and } a=\frac{5-7}{2}} \\\\ {a=\frac{12}{2} \text { and } a=\frac{-2}{2}}\end{array}[/tex]

We have asked negative solution. So a = -1

Thus the negative solution is -1

Answer:

Step-by-step explanation:

4(n+2)=2(n+10)

4n+8=2n+20

4n-2n+8=20

2n+8=20

2n=20-8

2n=12

n=12/2

n=6

Answer:

Step-by-step explanation:

16) 4 * y/5

The value of y should be greater than 5

For example if y = 6, then 4* 6/5 = 24/5 = 4.8

If y= 10, then 4* 10/5 = 4 * 2 = 8

y > 5

17) 1 pound = 16 ounce

3020 pounds =3020 * 16 = 48320 ounces

Answer: 7c ≤ 63

Ivan will buy at most 9 pounds of candy, which means that multiplying 9 by 7, the cost of the candy, will get your answer: 63. Plug these values into an inequality with a less than or equal to sign (≤) facing away from 63 and you're done!

The possible amounts Ivan will spend on candy can be represented as c ≤ 7.

Let's denote the amount Ivan will spend on candy as c. The cost of candy is $7 per pound, and Ivan will buy at most 9 pounds of candy. Therefore, the maximum amount he could spend on candy is 9 pounds multiplied by $7 per pound, which is 9c ≤ 63.

Since we are looking for possible amounts, we can rewrite this inequality as c ≤ 63/9, which simplifies to c ≤ 7.

So, the possible amounts Ivan will spend on candy are values less than or equal to $7.

The expression for the total cost of bats and gloves is b*x + 5*y. To find the total cost when three bats are bought, you need to know the costs of a bat (x) and a glove (y), and substitute those into the expression.

Assume that the cost of a baseball bat is 'x' dollars and each glove costs 'y' dollars. The total cost can be calculated by making 'b' the number of bats and adding the cost of 5 gloves. Therefore, the expression representing the total cost is b*x + 5*y.

Now, if the coach bought 3 bats, and we're given the costs for a bat and a glove, we can substitute '3' for 'b', 'x' for the cost of a bat, and 'y' for the cost of a glove.

For example, if a bat is $50 (x=50) and a glove is $20 (y=20), the total cost would be: 3*50 + 5*20 = 250 dollars.

https://brainly.com/question/34192827

#SPJ2

Final answer:

The expression for total cost of baseball bats and gloves is 'b times the number of bats plus 5 times the cost of a glove', where 'b' represents the cost of a bat. In the bat and ball problem, if a bat costs $1 more than the ball and together they cost $1.10, the ball costs $0.05. For three bats, the total cost is $3.15.

Explanation:

The question posed is a classic algebra problem from mathematics often used to illustrate a common cognitive error. To write an expression for the total cost of the baseball bats and gloves, let the cost of each bat be represented by 'b' and assume each glove has a fixed cost 'g'. The expression is then b times the number of bats plus 5 times the cost of a glove. However, we require additional information regarding the cost of individual gloves to complete this expression.

Turning to the bat and ball problem, if a bat and ball together cost $1.10, and the bat costs $1 more than the ball, we can set up the following equations where 'x' is the cost of the ball:

x + (x + $1) = $1.10

2x + $1 = $1.10

2x = $1.10 - $1.00

2x = $0.10

x = $0.05

Thus, the ball costs $0.05 and the bat costs $1.05. Finding the cost of three bats, we simply multiply $1.05 by 3 to get $3.15.

The explicit formula for the arithmetic sequence is [tex]a_n = 9 - 6n[/tex]

Solution:

Given that the arithmetic sequence is:

3, -3, -9, -15, -21, ...

To find: Explicit formula for the arithmetic sequence

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

Where [tex]a_n[/tex] is nth term of sequence

n is the term's location

[tex]a_1[/tex] is the first term of sequence

d is the common difference between terms

In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.

In the given sequence:

3, -3, -9, -15, -21, ...

[tex]a_1 = \text{ first term } = 3[/tex]

d = difference between any two terms in sequence

[tex]d = a_2 - a_1[/tex]

d = -3 - (3) = -6

Substituting the values in above formula,

[tex]a_n = 3 + (n - 1)(-6)\\\\a_n = 3 -6n + 6\\\\a_n = 9 - 6n[/tex]

Thus the explicit formula to find any term in sequence is found

Answer:

The graph is plotted below.

One ordered pair as solution is (0, 0).

Step-by-step explanation:

Given:

The inequality is given as:

[tex]y\geq x-5[/tex]

In order to plot it, we first replace '≥' by '=' sign. This gives,

[tex]y = x-5[/tex]

Now, we plot the above line. For that, we need the x and y intercepts.

At x-intercept, y = 0. So,

[tex]0=x-5\\x=5[/tex]

The point is (5, 0)

At y-intercept, x = 0. So,

[tex]y=0-5\\y=-5[/tex]

The point is (0, -5)

Now, plot these two points and draw a line passing through these two points. The graph is shown below.

Now, replace '=' by '≥' sign. Since, 'y' is greater than equal to 'x - 5'. So, the solution region is above the given including the values on the line.

Therefore, any ordered pair in the solution region is a solution of the given inequality. From the graph, one such ordered pair is (0, 0).

This can be verified from the inequality also.

[tex]0\geq 0-5\\0\geq -5(True)[/tex]

So, one ordered pair is (0, 0).

range: ]−∞,4]

Step-by-step explanation:

Look at the photo below for more info.

:)

The domain of the function f(x) = -3(x-5)² +4 is all real numbers, written as (-∞, ∞). The range, or possible values of f(x), is (-∞, 4] since the parabola opens downwards and the maximum value is 4.

The function f(x) = -3(x-5)² +4 is a parabola that opens downwards. The domain of a function is the set of all values that x can take. For any parabolic function, the domain is always all real numbers, which we could write as (-∞, ∞).

The range of a function refers to the possible values of f(x). In this case, since the parabola opens downwards, the maximum value of f(x) is at the vertex of the function. This parabola's vertex is at (5,4), so its maximum, and thus the upper boundary of the range, is 4. The parabola continues downwards to negative infinity, so the range is (-∞, 4].

Therefore, the domain is (-∞, ∞), and the range is (-∞, 4].

Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15

Solution:

The function that models the yield is:

[tex]f(x) = -x^2 + 20x + 75[/tex]

The average rate of change of f(x) from x = a to x = b is given by the formula:

[tex]\text{ average rate of change }=\frac{f(b)-f(a)}{b-a}[/tex]

Find and interpret the average rate of change from year 5 to year 15

[tex]f(5) = -(5)^2 + 20(5) + 75\\\\f(5) = -25 + 100 + 75\\\\f(5) = 150[/tex]

[tex]f(15) = - (15)^2 + 20(15) + 75\\\\f(15) = -225 + 300 + 75\\\\f(15) = 150[/tex]

Thus average rate of change:

[tex]\text {average rate of change}=\frac{f(15)-f(5)}{15-5}[/tex]

[tex]\text {average rate of change}=\frac{150-150}{10}=0[/tex]

Thus Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15.

Final answer:

The average rate of change in wheat yield from year 5 to year 15 is 0 pounds per acre per year, symbolizing that there was no change in the crop yield between these years.

Explanation:

To find the average rate of change of the wheat yield from year 5 to year 15, we will apply the function f(x) = −x² + 20x + 75 to these years and then calculate the rate of change. First, we'll find the yield for year 5 and year 15:

Next, we'll calculate the average rate of change using these yields:

Average rate of change = (f(15) - f(5)) / (15 - 5) = (150 - 150) / (10) = 0

Therefore, the crop yield did not change from year 5 to year 15. The function indicates that at both year 5 and year 15, the farmer's land yielded 150 pounds per acre, so the average rate of change in yield over this period is 0 pounds per acre per year.
