The statement about the linear equation 3a + 1/3(6a −9) = 1/2(10a − 6) that is true is: "The equation has an infinite number of solutions." (Option B)

A linear equation is defined as an equation with a maximum of one degree. A nonlinear equation is one with a degree greater than or equal to two.

On the graph, a linear equation looks like a straight line. On the graph, a nonlinear equation creates a curve.

To justify the above answer, we state the linear equation above:


3a + 1/3(6a −9) = 1/2(10a − 6) ; Simplified by opening the brackets, we have

3a + 2a − 3 = 5a − 3; collecting like terms on the left side, we have

5a -3 = 5a -3

Because 5a -3 = 5a -3, the expression holds true regardless of what integer or value a represents. Hence, it has an infinite number of solutions.

The value of angle ABE is 52°

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted by triangle ABC.

The interior angles of a triangle are the inside angles formed where two sides of the triangle meet.

The sum of interior angle in a triangle is 180°

Angle EBD = 180-(90+27)

= 180-117

= 63°

angle ABE + EBD = ABD

ABE = ABD - EBD

ABE = 115-63

= 52°

The probability of 35 people being selected before the first person with a phobia is chosen does not provide sufficient evidence to suggest that the ADAA claim is false.

To determine whether the ADAA claim is false, we need to perform a statistical hypothesis test that compares the sample proportion of adults with phobias to the ADAA with an estimation of 8.7%.

This would involve collecting data on a random sample of adults and can be calculated as the sample proportion of adults with phobias, and compared to the ADAA estimate of 8.7%.

If the sample proportion is totally different from 8.7%, we can conclude that there is evidence to suggest that the ADAA claim and false.

However, without performing a statistical hypothesis test, we cannot make a conclusion about the validity of the ADAA claim which is based on the probability of 35 people being selected before the first person with a phobia is chosen.

The "success" is identifying an adult with a specific phobia, and the probability of success is p = 0.087.

We can show the given situation utilizing a mathematical dissemination, which portrays the quantity of free Bernoulli preliminaries expected to make the principal progress. For this situation, the "achievement" is distinguishing a grown-up with a particular fear, and the likelihood of achievement is p = 0.087.

Likelihood that the fifth grown-up chosen will be the main individual with a fear:

The likelihood that the main individual with a fear is chosen on the fifth preliminary is:

P(X = 5) = (1 - p)^4 * p

= (0.913)^4 * 0.087

= 0.0073 (adjusted to four decimal spots)

Likelihood that no less than eight grown-ups will be chosen prior to distinguishing an individual with a particular fear:

The likelihood that the primary individual with a fear is chosen after at least eight preliminaries is:

P(X > 8) = 1 - P(X ≤ 8)

= 1 - [(1 - p)^7 * p + (1 - p)^6 * p + ... + (1 - p)^1 * p + (1 - p)^0 * p]

= 1 - 0.2663 (determined utilizing a mathematical conveyance table or number cruncher)

= 0.7337 (adjusted to four decimal spots)

Mean number of grown-ups u that should be chosen prior to distinguishing an individual with a particular fear:

The mean (expected) number of preliminaries expected to make the principal progress is:

u = 1/p

= 1/0.087

= 11.49 (adjusted to one decimal spot)

So overall, we want to choose around 11.49 grown-ups prior to tracking down the principal individual with a particular fear.

Likelihood that the 35th grown-up is the main individual with a particular fear:

The likelihood that the primary individual with a fear is chosen on the 35th preliminary or later is:

P(X > 34) = (1 - p)^34

= (0.913)^34

Let's assume that John buys x boxes of Cereal A and y boxes of Cereal B. Then, we can write the following system of inequalities based on the nutrient and calorie requirements:

10x + 5y ≥ 500 (minimum 500 units of vitamins)

5x + 10y ≥ 600 (minimum 600 units of minerals)

15x + 15y ≥ 1200 (minimum 1200 calories)

We want to minimize the cost, which is given by:

0.5x + 0.4y

This is a linear programming problem, which we can solve using a graphical method. First, we can rewrite the inequalities as equations:

10x + 5y = 500

5x + 10y = 600

15x + 15y = 1200

Then, we can plot these lines on a graph and shade the feasible region (i.e., the region that satisfies all three inequalities). The feasible region is the area below the lines and to the right of the y-axis.

Next, we can calculate the value of the cost function at each corner point of the feasible region:

Corner point A: (20, 40) -> Cost = 20

Corner point B: (40, 25) -> Cost = 25

Corner point C: (60, 0) -> Cost = 30

Therefore, the minimum cost is $20, which occurs when John buys 20 boxes of Cereal A and 40 boxes of Cereal B.

The change in the  angular velocity and number of revolutions  is given as,

when the angular velocity decreases the number of revolutions also decreases.

The rotation rate, which refers to how quickly an item rotates or circles in relation to another point, is measured vectorially by angular velocity.

Angular velocity can be defined as the speed at which an item rotates or revolves around an axis. The Greek letter omega stands for angular velocity. The SI unit of angular velocity is radians per second because it is measured in angle per unit time.

The only distinction between revolution and rotation is that the axis of rotation in a revolution is located outside the body. Both motions of an item or body in space are circular.

Answer:

It is true that 20% and 30% make 50%. But in the context of sale prices it is essential to keep track of the wholes to which these percents apply. For the backpack, the 30% discount applies to the original $60 price: 30% of $60 is 0.3×60=18 making the discount on the backback $18. So after using the coupon, the backpack price becomes $42. Emily's additional 20% coupon applies not to the original backpack price but to the discounted price of $42: 20% of $42 is $8.40. Emily would need to save an additional $12 off the $42 price in order to buy the backpack for $30 so her calculations are not correct.

As seen in part (a), Emily's coupon lowers the discount rack price by $8.40 so she will pay

42−8.40=33.60

The percentage population increase from 2001 to 2011 is 50%.

To calculate the percentage population increase from 2001 to 2011, you need the population figures for both years. Let's assume the population in 2001 was 100,000 and in 2011 it was 150,000.

The formula to calculate the percentage increase is:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Plugging in the values:

Percentage Increase = ((150,000 - 100,000) / 100,000) * 100 = (50,000 / 100,000) * 100 = 0.5 * 100 = 50%

Therefore, the percentage population increase from 2001 to 2011 is 50%.

Please note that the actual population figures for the respective years need to be used in the calculation to obtain an accurate result. The example above is for illustrative purposes.
