multiply the second equation by −2

In the addition-subtraction method, the two equations in the system are added or subtracted to create a new equation in one variable. In order for the new equation to have only one variable, the other variable must cancel out.

multiply the second equation by −2:

2x + 4y = 4

−2x − 6y = −26

→ −2y = −22

a do not replace marbles after picking them;do replace marles

For independent events in probability, you should replace the marbles after picking them, as this keeps the likelihood of each draw the same. For dependent events, do not replace the marbles after picking them, as each draw influences the subsequent draws.

The concept being discussed here is that of independent and dependent events in probability. When selecting marbles from a bag, the nature of the event (whether it is independent or dependent) depends on whether the marble is replaced after being selected or not.

To make your selections independent events, you should replace the marbles after picking them. This assumes that each event (the selection of a marble) does not affect the outcome of the other events. For example, if you picked a blue marble first and replaced it, the likelihood of picking a blue marble on the second draw remains the same.

On the other hand, to create dependent events, you should not replace the marbles after picking them. The outcome of the first event (e.g., removing a blue marble) directly influences the probability of the next event, because there is now one less blue marble in the bag to choose from.

Answer:

Solution of equation :-

x = 1 or x = -4

Step-by-step explanation:

The given quadratic equation is x² + 3x - 4 = 0

To find the solution

Using splitting method

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0   (take x and 4 as common)

(x - 1)(x + 4) = 0

(x - 1) = 0  or (x +  4)= 0

If x - 1 = 0 then x = 1

If x + 4  = 0 then x = -4

Answer:

x^2 + y^2 = 36

Step-by-step explanation:

Just add 36 to both sides. This is a circle with the center at the origin and radius 6.

Final answer:

The equation in standard form for the circle x² + y² – 36 = 0 is x² + y² - 9x - 12y + 36 = 0.

Explanation:

The equation in standard form for the circle x² + y² – 36 = 0 is:

x² + y² - 9x - 12y + 36 = 0

This equation can be obtained by completing the square. Rewrite the equation as: (x² - 9x) + (y² - 12y) = 36. Complete the square for both the x and y terms by adding the square of half the coefficient of each term.

To complete the square for the x terms, add (9/2)² = 81/4, and for the y terms, add (12/2)² = 36 to both sides of the equation.

Simplify the equation to: x² - 9x + (81/4) + y² - 12y + 36 = 36 + (81/4) + 36.

Combine like terms and simplify further to obtain the standard form of the equation: x² + y² - 9x - 12y + 36 = 0.

Answer:

A lot. probably down to a 60

6 CM would make it 60mm because you would do length timeth width

" The area of the rectangle is 60 cm², which is equivalent to 6000 mm².

To calculate the area of a rectangle, one multiplies the length by the width. In this case, the rectangle has a width of 12 cm and a length of 5 cm. Therefore, the area (A) is calculated as follows:

[tex]\[ A = \text{length} \times \text{width} \][/tex]

[tex]\[ A = 5 \, \text{cm} \times 12 \, \text{cm} \][/tex]

[tex]\[ A = 60 \, \text{cm}^2 \][/tex]

The area is obtained in square centimeters (cm²) because we multiplied two lengths measured in centimeters.

 Now, to convert the area from square centimeters to square millimeters, we need to remember that there are 10 millimeters in a centimeter. Therefore, when converting from cm² to mm², we must square the conversion factor because we are dealing with a two-dimensional measurement:

[tex]\[ 1 \, \text{cm}^2 = (1 \, \text{cm})^2 = (10 \, \text{mm})^2 = 100 \, \text{mm}^2 \][/tex]

Now, we can convert the area from cm² to mm²:

 [tex]\[ 60 \, \text{cm}^2 = 60 \times 100 \, \text{mm}^2 \][/tex]

[tex]\[ 60 \, \text{cm}^2 = 6000 \, \text{mm}^2 \][/tex]

The function with a range of (-π/2, π/2) is the arc sine function, denoted as y = sin-1(x) or y = arcsin(x).

The range of a function is the set of all possible output values it can produce. When referring to a function with a range of (-π/2, π/2), we are usually considering trigonometric functions, particularly the inverse trigonometric functions. The function that has a range between -π/2 and π/2 is the arc sine function, denoted as y = sin-1(x) or y = arcsin(x). This is because the arc sine function is the inverse of the sine function, which oscillates between -1 and 1, and thus its inverse must have a range where the angle could be between -π/2 and π/2 to accommodate this domain.

The sine function itself, which a student might initially think of due to its oscillation, has a domain of all real numbers and a range of [-1,1], so it does not fit the criteria given by the range (-π/2, π/2). It is important to recognize that, while a sine function oscillates between +1 and -1, its inverse function, arc sine, is the one with the specified range as mentioned in the question.

19/8=2.3

The correct option is D) Yes, the probability of not liking country is different from the probability of not liking country given that they listen to the station.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.

We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given that, a local radio station surveyed people going into a grocery store about whether or not they liked country and if they listed to that station,

We need to determine that if listening to the radio station independent of liking country music,

So, here the answer will be yes, because both the events are not connected to each other.

The probability of not liking or liking the country music is nowhere related to whether a person is listening to the radio station or not.

There are 6 points on a circle.

We have a sum of angles in a circle that is equal to 360°.

Anna can only see 2 points which is a third of a points there are.

That means her spectrum is 360°/3 which is 120°.

The answer is B. 120°.

Hope this helps.

Brainliest would be amazing.

Final answer:

When six posts are evenly spaced around a circle, they divide the circle into six equal sections of 60 degrees each. If Anna can see across two sections, the measure of angle A (m∠A) is 120 degrees.

Explanation:

In this question, we are asked to find the measure of angle A (m∠A) when six posts are evenly spaced along a circular wall. If six posts are evenly distributed around a circle, they divide the circle into six equal sections. Since a circle has 360 degrees, each section between two posts equals 360°/6 = 60°. When Anna stands at point A, she can see across two such sections, so to find the measure of angle A, we simply add the degrees of the two sections:

Measure of angle A (m∠A) = 60° + 60° = 120°

Therefore, the correct answer to the question is 120°, meaning Anna can see an angle of 120 degrees between the two posts that are visible to her from her standing point at A.

ANSWER

A. Right

EXPLANATION

A tangent to a circle touches the circle at only one point.

The point where a tangent and a radius meet at is called the point of tangency.

The tangent to a circle meets the radius of a circle at a right angle.

This is because the angle between the tangent and the radius of the circle is 90°

The correct answer is A.

Final answer:

When a radius and a tangent intersect at the point of tangency, they form a right angle. This fact is part of basic geometric principles covered in high school mathematics.

Explanation:

The type of angle formed when the radius of a circle and a tangent intersect at the point of tangency is a right angle. This geometric principle is a result of the fact that a tangent to a circle is perpendicular to the radius at the point of tangency. This concept falls within the branch of mathematics known as geometry, which is a crucial topic in high school math education.

Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = [tex]\frac{1}{3}[/tex] x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = [tex]\frac{1}{3}[/tex] x + 7

Subtract [tex]\frac{1}{3}[/tex] x from both sides

[tex]\frac{8}{3}[/tex] x + 15 = 7 ( subtract 15 from both sides )

[tex]\frac{8}{3}[/tex] x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

Answer:p(side effects| child)=0.42

P(side effects|adults)=0.12

Step-by-step explanation:

Children are twice as likely as adults to experience side effects from the new drug.

The probability that an adult has side effects is 0.12,

while the probability that a child has side effects is 0.42.

This means that children are more likely to experience side effects from the new drug than adults.

We can calculate the probability of side effects for each group by dividing the number of people who experienced side effects by the total number of people in the group:

Probability of side effects in adults = [tex]\frac{6}{50}[/tex] = 0.12

Probability of side effects in children = [tex]\frac{21}{50}[/tex]= 0.42

First get the sum of digits 0 through 9: 0+1+2+...+9=45. Call this sum S for short.

Then notice that the sum of the digits for 10 through 19 is the sum S + 10.

Then notice that the sum of digits 20 through 29 is S + 20, and do so until you hit 100. 100 through 109 is the same as 10 though 19 which you know is S + 10, and finally add the sum of digits of 110, i.e., 2.

Total = S + (S + 10) + (S + 20) + ... + (S + 90) + (S + 10) +2 =

= 11 * S + 10 * (S + 1) + 2 = 11 * 45 + 10 * 46 + 2 = 957

Answer:

957

Step-by-step explanation:

We first calculate the sum of all digits used to write the whole numbers 0 through 99. If we consider all such numbers as two-digit (e.g. write 04 instead of 4), the sum of digits will be unchanged. Then we see that each digit appears an equal number of times in the ones place, and similarly for the tens place, meaning it appears a total of $2\cdot \frac{100}{10} = 20$ times. Thus the sum of all digits used to write the whole numbers 00 through 99 is $20\cdot (0 + 1 +\cdots + 8 + 9) = 900$. The sum of the digits from 100 to 110 is just $(1 + 0) + (1 + 1) + (1 + 2) + \cdots + (1+9) + 2 = 57$. Thus our final answer is $900 + 57 = \boxed{957}$.

At the most 308 pounds / exactly 308 ((2000-150)/6=308) hope it helps

Answer:

At most 308 pounds

Step-by-step explanation:

Let x pounds be the new weight of the sacks,

⇒ The weight of 6 sacks = 6x,

Now, the weight of Kevin = 150 pounds,

Thus, the total weight Kevin and 6 sacks = 150 + 6x,

Given,

The capacity of the elevator is 2,000 pounds,

⇒ 150 + 6x ≤ 2000

⇒ 6x ≤ 2000 - 150    ( Subtraction property of inequality )

⇒ 6x ≤  1850

⇒ x ≤ 308.33 ≈ 308

Hence, the weight of each sack is approximately atmost 308 pounds.
