Answer:

NO. |-6| = 6 - a positive integer

Step-by-step explanation:

|a| = a for a ≥ 0

examples

|2| = 2, |0| = 0, |0.56| = 0.56

|a| = -a for a < 0

examples

|-2| = -(-2) = 2, |-100| = -(-100) = 100, |-0.25| = 0.25

Therefore your answer:

|-6| = 6 > 0

To determine the time needed to layout a full magazine issue, multiply the time taken to layout 1/16 of an issue (3 days) by 16, resulting in 48 days total.

If a magazine can layout 1/16 of an issue in 3 days, then to calculate how many days it takes to layout one entire issue, we simply multiply the number of days it takes to layout 1/16 of the issue by 16.

This is because if 1/16 takes 3 days, then 1/8 (which is twice the amount of 1/16) would take twice as long

(3 days * 2 = 6 days),

and similarly, we can scale up to the full issue (1/1) by multiplying 3 days by 16.

The calculation would be:

Identify the portion of the issue completed: 1/16.

Identify the time taken for this portion: 3 days.

Calculate the time for the whole issue: 3 days * 16 = 48 days.

So, it would take 48 days to layout one full issue.

Option 3 is right

z37 is between 2 and 3 standard deviations of the mean.

Step-by-step explanation:

Let X be a random variable which represents the mean number of miles that the employees in a department live from work

X is normal (N(29,3.6)

WE have to find Z score for X

Z =[tex]\frac{x-29}{3.6}[/tex]

=2.22

i.e. 37 is 2.22 std deviations from the mean.

In other words, z37 is between 2 and 3 standard deviations of the mean.

The z-score for z37 is approximately 2.22. This indicates that it lies between 2 and 3 standard deviations of the mean. Hence, the correct statement is: z37 is between 2 and 3 standard deviations of the mean.

To determine which statement is true regarding the z-score for the value z37, we need to calculate the z-score using the given mean and standard deviation.

This means that z37 is approximately 2.22 standard deviations away from the mean. Therefore, the correct statement is:

z37 is between 2 and 3 standard deviations of the mean.

In a normal distribution, about 95 percent of the x values lie within two standard deviations, and about 99.7 percent lie within three standard deviations of the mean.

Answer:

The slope is 3 (answer choice A).

Step-by-step explanation:

Take a look at the two given points, (2, -5) and (4, 1).  As we move from the first point to the second, x increases by 2 and y increases by 6, so that the slope is m = 6/2, or 3.

To solve this problem yo must apply the proccedure shown below:

First of all this is a very poor question, and you should question it a bit. What are these figures? Are they regular? (first 2). Is the last one a parallelogram. I'm going to assume that the yellow one is a rectangle and the middle one is a pentagon and the last one is a parallelogram.

Yellow

A has 4 right angles (That's the property of a rectangle).

Green

B has 5 angles that are equal to 108 degrees. If you draw a 2 lines from any vertex you get 3 triangles. The size of the interior angles totals 3 triangles * 180 degrees = 540 degrees.

540/3 = 108.

Each angle in the interior is 108 degrees.

B has 5 angles all equal 108 degrees. All 5 are obtuse.

Answer: D

y=10x+5 because x=3 so 10*3=30 and 30+5=35 which would mean that $35 is the lowest amount you can spend.

To stay within a $50 daily budget for activities, equations are created to determine the number of tubes (t) and canoes (c) that can be rented. With tube rentals at $5 and canoe rentals at $10, the group of ten can only rent tubes (t = 10), as renting canoes would exceed the budget (c = 0).

The question involves creating and solving a budget constraint problem similar to the examples provided for Janet Bain and Mr. Higgins. To accommodate the group of 10 people with a budget of $50 per day for activities, we need to write equations to determine how many tubes (t) and canoes (c) can be rented. We know that tube rentals cost $5 and canoe rentals cost $10. Each canoe holds up to three people.

First, we write an equation that represents the number of tubes and canoes needed:

Everyone needs a tube: t = 10

Canoes can hold three people: 3c ≥ 10 (since not everyone needs to be in a canoe at the same time)

Next, we write an equation for the total cost to remain within the budget: 5t + 10c ≤ 50 (cost of tubes plus canoes must be less than or equal to $50)

Using t = 10, we can substitute t in the cost equation: 5(10) + 10c ≤ 50

50 + 10c ≤ 50

10c ≤ 0

From the final inequality, c = 0; meaning you cannot rent any canoes if you're buying a tube for each person and staying within a $50 budget. Therefore, the group can only rent tubes, with 0 canoes.

c > -13/10

The > should have _ under it.

The correct solution is shown in the graph (D)

Given that the budget is $24 and the minimum is 7 tubs, the fourth graph shows the area in which both constraints are satisfied: triangular area between the points

7 small tubs

8 small tubs

3 large and 4 small tubs

Lets x = # of small tub of popcorn and y = # of large tub of popcorn

She needs to buy at least 7 tubs of popcorn: x + y >= 7

Each small tub of popcorn costs $3 and each large tub of popcorn costs $4 but she only has $24 in her wallet.

3x + 4y <= 24

So now you have the system of inequalities

x + y >= 7

3x + 4y <= 24

Find x and y intercepts of blue line

x + y = 7

x = 0 then y = 7

y = 0 then x = 7

The inequality sign is >= so it's above.

The blue line,  B and D are matching the results

Find x and y intercepts of red line

3x + 4y = 24

x = 0 then 4y = 24; y = 6

y = 0 then 3x = 24;   x = 8

The inequality sign is <= so it's below.

The red line,  Only B is matching

Answer

D is the solution of the system of inequalities.

Let x = a number

3(6 - x) = -9

Divide both sides of equation by 3.

6 - x = -3

Subtract 6 on both sides of equation.

-x = -9

Divide both sides of equation by -1.

x = 9

The number is 9.

The difference between a number and six is [tex] x-6 [/tex]. Twice this difference is [tex] 2(x-6) [/tex]. If you want this difference to be negative, six, you have

[tex] 2(x-6)=-6 [/tex]

Divide both sides by 2:

[tex] x-6 = -3 [/tex]

Add 6 to both sides:

[tex] x = 3 [/tex]

M= change in y /change in x

The graph of an absolute value function is a V or inverted V. The x-coordinate of the V's vertex provides the function's line of symmetry, and the y-coordinate of the V's vertex shows the minimum or maximum value of the function.

An absolute value function is a function that contains an algebraic expression within absolute value symbols. The graph of an absolute value function is a symmetrical V or inverted V, depending on the direction of the opening. The vertex of the V, which is the minimum or maximum point of the graph, provides two important pieces of information: the x-coordinate of the vertex gives us the equation's line of symmetry, and the y-coordinate represents the minimum or maximum value of the function, depending on the opening direction.

Let's say, for example, we have the graph of the function |x - 3| + 2. The vertex of this function is at the point (3, 2). Therefore, the line of symmetry is x = 3, and the minimum value of the function is 2.

Step-by-step explanation:

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

0.75 per ticket. So cost of 18 tickets= 0.75 * 18 = $13.5

Kendall spent $13.50 for tickets . Total spent = $33.50

Total spent = ticket cost + admission cost

33.50 = 13.50 + admission

Admission cost = 33.50 - 13.50 = $20

(a)  y to represent the total cost , x to represent the number of ride tickets.

'b' represents the admission cost

(b)  General form of linear equation is y=mx+b

m = 0.75 and b = admission cost = 20

So equation becomes y = 0.75x + 20

(c) Initially, she has to pay the admission price $20. then 0.75 per ticket.

The value of x changes depends on the number of tickets she wants to buy.

y is the total cost she has to pay for x tickets with admission price

Answer:

Her speed driving in nice weather is 50 mph and in thunderstorm is 32 mph.

Step-by-step explanation:

Barbara drives 50 miles in clear weather and then encounters a thunderstorm for the last 16 miles.

Suppose, her speed in nice weather is  [tex]x[/tex] mph.

As she drives 18 mph slower through the thunderstorm than she does in clear weather, so her speed in thunderstorm will be: [tex](x-18) mph[/tex]

We know that,  [tex]Time = \frac{Distance}{Speed}[/tex]

So, the time of driving in clear weather [tex]=\frac{50}{x}[/tex] hours

and the time of driving in thunderstorm [tex]=\frac{16}{x-18}[/tex] hours.

Given that, the total time for the trip is 1.5 hours. So, the equation will be......

[tex]\frac{50}{x}+ \frac{16}{x-18}=1.5 \\ \\ \frac{50x-900+16x}{x(x-18)}=1.5\\ \\ \frac{66x-900}{x(x-18)}=1.5 \\ \\ 1.5x(x-18)=66x-900\\ \\ 1.5x^2-27x=66x-900\\ \\ 1.5x^2-93x+900=0\\ \\ 1.5(x^2 -62x+600)=0\\ \\ x^2 -62x+600=0\\ \\ (x-50)(x-12)=0[/tex]

Using zero-product property.........

[tex]x-50=0\\ x=50\\ \\ and\\ \\ x-12=0\\ x=12[/tex]

We need to ignore [tex]x=12[/tex] here, otherwise the speed in thunderstorm will become negative.

So, her speed driving in nice weather is 50 mph and her speed driving in thunderstorm is (50-18) = 32 mph

Let  us assume rate of other person = x miles per hour.

Rate of first person is 3 miles per hours faster than other.

Therefore, rate of first person = (x+3) miles per hour.

Total distance between them = 20 miles.

And total time taken by them is 2 hours.

We know, distance, time and rate relation:

Distance = Rate × Time.

Therefore, distance covered by other person = x * 2 = 2x.

Distnace covered by first person = (x+3)*2.

Total distance covered by both = 20 miles.

We can setup an equation

Total distance covered by both  = Distnace covered by first person + distance covered by other person.

2(x+3) +2x = 20.

Now, we can solve the eqation for x.

2x +6 +2x = 20.

4x +6 =20.

Subtracting 6 from both sides, we get

4x +6-6 =20-6

4x = 14.

Dividing both sides by 4, we get

x=3.5

Rate of first person = (x+3) = 3.5+3 = 6.5 miles per hour.

Step-by-step explanation:

The set of coordinates satisfies the equations 3x − 2y = 15 and 4x − y = 20 is (5, 0).

Option C is the correct answer.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

3x - 2y = 15 _____(1)

4x - y = 20 _____(2)

The point of intersection of (1) and (2).

3x - 2y = 15

3x = 15 + 2y

x = (15 + 2y) / 3 _____(3)

4x - y = 20

4x = 20 + y

x = (20 + y) / 4 ______(4)

From (3) and (4) we get,

(15 + 2y) / 3 = (20 + y) / 4

4(15 + 2y) = 3(20 + y)

60 + 8y = 60 + 3y

8y - 3y = 0

5y = 0

y = 0

Now,

y = 0 in (1) or (2) we get,

3x = 15

x = 5
