Interest in the trainings offered at the pet shelter decreased from summer to winter. This change can be represented as -83. What is the absolute value of -83?

Answer:

B) (4, 0)

C) (0, -1)

E) (2, 3)

Step-by-step explanation:

If we see the rule of function then it says that,

a function is a special relationship where each input, x,  has a single output, y.

It means that for every value of x there SHOULD be a different value of y.

A)

(-3,-2) Rejected

because when x = 3, y = -2  

D)

(1, 6) Rejected

because when x = 0, y = 6  

F)

(-5, 9) Rejected

because when x = 4, y = 9  

Answer:

The correct options are A, D and E.

Step-by-step explanation:

The given set of ordered pairs represents a function

[tex]f=\{(-5, 3), (4, 9), (3, -2), (0, 6)\}[/tex]

We need to find THREE ordered pairs that could be added to the set that would allow f to remain a function.

A relation is a function if there exist unique value of y for each value of x.

The x values for given function are -5, 4, 3 and 0.

If we add (-3,-2) in the given set, then we unique value of y for each value of x.  So, option A is correct.

If we add (4,0) in the given set, then we have y=0 and y=9 at x=4. Since the set have more than one value of y for same x-value, therefore option B is incorrect.

If we add (0,-1) in the given set, then we have y=-1 and y=6 at x=0. Since the set have more than one value of y for same x-value, therefore option C is incorrect.

If we add (1,6) in the given set, then we unique value of y for each value of x.  So, option D is correct.

If we add (2,3) in the given set, then we unique value of y for each value of x.  So, option E is correct.

If we add (-5,9) in the given set, then we have y=9 and y=3 at x=-5. Since the set have more than one value of y for same x-value, therefore option F is incorrect.

Therefore the correct options are A, D and E.

Final answer:

The probability of Robert eating two mint sticks consecutively from a bag of candy is 3/95, which is found by multiplying the individual probabilities of selecting a mint stick on the first and second draw.

Explanation:

The question involves calculating the probability that the first two pieces of candy Robert eats are both mint sticks. To find this probability, follow a step-by-step process to consider all possible outcomes.

Step 1: Probability of first mint stick

Initially, Robert has 20 pieces of candy with 4 being mint sticks. So, the probability of picking a mint stick first is:

4 mint sticks / 20 total pieces = 1/5 or 0.20.

Step 2: Probability of second mint stick

After eating one mint stick, there remain 3 mint sticks out of 19 total pieces. Thus, the probability now becomes:

3 mint sticks / 19 total pieces = 3/19.

Step 3: Combined probability

To find the probability of both events happening consecutively, multiply the separate probabilities:

(1/5) * (3/19) = 3/95, which simplifies to 0.0316, or about 3.16% chance.

Therefore, the correct answer is C. 3/95.

Answer:

16.7%

Step-by-step explanation:

Total number of cases sold = 24

In order to find what percentage of cases were sold we first need to know the total number of cases that the merchant had.

Let the total number of cases the merchant initially had was x. After selling 24 cases, the number of cases he is left with is x - 24

According to the statement, the number of cases sold (i.e. 24) is 20% of the number of cases the merchant originally had (i.e. x - 24)

This can be written as:

24 is 20% of x - 24

In equation form this becomes:

24 = 20% of ( x - 24)

24 = 0.20(x - 24)

24 = 0.20x - 4.8

24 + 4.8 = 0.20x

28.8 = 0.20x

x = 144

This means the merchant initially had 144 cases of tapes. He sold 24 of them. So the percentage of cases he sold will be:

[tex]\frac{24}{144} \times 100\%\\\\ = 16.7%[/tex]

Therefore, the merchant sold 16.7% of the cases of tapes.

Answer:

The value of cosФ = -√5/3

Step-by-step explanation:

∵ sinФ = 2/3

∵ tanФ is less than 0

* Lets think about that:

 the value of sin is positive and the value of tan is negative

 according to ASTC rule:

 - All are positive in the first quadrant

 - sin only positive in the second quadrant

 - tan only positive in the third quadrant

 - cos only positive in the fourth quadrant

∴ Angle Ф lies on the second quadrant

∴ The value of cosФ is less than 0

∵ sin²Ф + cos²Ф = 1

∵ sinФ = 2/3

∴ (2/3)² + cos²Ф = 1

∴ cos²Ф = 1 - 4/9 = 5/9

∴ cosФ = ± √5/3

∵ Angle Ф lies on second quadrant

∴ cosФ = -√5/3

The cosine of the angle θ, given that sine θ is 2/3 and tangent θ is negative, is -√(5/9) since the angle is in the second quadrant.

If the sine of an angle (θ) is 2/3 and the tangent of that angle is less than zero, this indicates that the angle is in the second or fourth quadrant, where tangent values are negative. However, since sine is positive, the angle θ must be in the second quadrant. To find the cosine of θ, we can use the Pythagorean identity: sin² θ + cos² θ = 1. Substituting the sine value, we get (2/3)² + cos² θ = 1, which simplifies to 4/9 + cos² θ = 1. Solving for cosine gives us cos² θ = 1 - 4/9 = 5/9. The cosine value itself will be negative because cosine is negative in the second quadrant, so cos θ = -√(5/9).

Answer:

360 points in total, Kevin needs 96 more.

Step-by-step explanation:

88 x 3 is  264

To get a mean of 90, Kevin needs 360 points in total because 90 x the 4 tests is 360.

360 - 264 is 96

Answer:

$791

Step-by-step explanation:

Find the equation of the line passing thru  (30, 1,181) and (44, 1,363),   The y-intercept of this equation will answer this question:  it represents the annual golf pass.

Moving from (30, 1,181) to (44, 1,363), we see x increasing by 14 from 30 to 44 and y increasing by  182   from 1181 to 1363.

Thus, the slope of this line is m = rise / run = 182 / 14 = 13.

Subst. the knowns (30, 1,181) and m = 13 into the standard equation for a straight line in slope-intercept form, y = mx + b, we get:

1181 = 13(30) + b.  Then 1181 - 390 = 791.

Answer: Christina weighs 98 pounds.

Step-by-step explanation: The formula to solve this problem is x + 17 + x = 179, where x equals Sarah’s weight.

X + 17 + x = 179

First you need to combine the x values:

2x + 17 = 179

Next, subtract 17 from both sides:

2x = 162

Finally, divide both sides by 2:

X = 81

Sarah’s weight is 81 pounds and Christina weighs 17 pounds more, which is 98 pounds. You can double check your work by adding both of their weights (98 + 81) to make sure that your answer is correct.

Final answer:

By setting up a system of equations with the given information, we can solve for Christina's weight. Christina weighs 125 pounds.

Explanation:

To determine how much Christina weighs, we can set up an equation based on the information given. Let's define Sarah's weight as 's' and Christina's weight as 'c'. According to the question, Christina weighs 17 pounds more than twice Sarah's weight. So we can write the equation as:

c = 2s + 17

The combined weight of Christina and Sarah on the freight scale is 179 pounds. We represent this with another equation:

c + s = 179

Now we have a system of two equations:

Substituting the expression for 'c' from the first equation into the second equation gives us:

(2s + 17) + s = 179

Combining like terms, we have:

3s + 17 = 179

Moving 17 to the other side by subtracting 17 from both sides:

3s = 179 - 17

3s = 162

Dividing both sides by 3 to find Sarah's weight:

s = 162 / 3

s = 54

Now that we know Sarah weighs 54 pounds, we can find Christina's weight using the first equation:

c = 2(54) + 17

c = 108 + 17

c = 125

So, Christina weighs 125 pounds.

Answer: [tex]10\sqrt{2}units[/tex]

Step-by-step explanation:

You must apply the Pytagorean theorem, which is shown below:

[tex]a^2=b^2+c^2[/tex]

Where:

a is the hypotenuse and b and c are the legs of the triangle.

Then, if you know the lenght of the legs of the triangle, you can solve for the hypotenuse.

Therefore, keeping the above on mind, you obtain the following result:

[tex]a=\sqrt{b^2+c^2}[/tex]

[tex]a=\sqrt{(10units)^2+(10units)^2}\\a=10\sqrt{2}units[/tex]

The length of the hypotenuse of the triangle is 10√2 units

The triangle is a right angle triangle.

Right angle triangles are triangle that has one of its angles as 90 degrees.

Using Pythagoras theorem, we can find the length of the hypotenuse with the length of the two legs.

Therefore,

c² = 10² + 10²

c² = 100 + 100

c = √200

c = 10√2

Hope this helps.

Answer:

Step-by-step explanation:

Givens

$17.50 per hour and $1,500 bonus at the end of the year, that is, at the ends of the 52 weeks.

If you work 35 hours per week for 52 weeks, with this plan, you gain

[tex]17.50 \times 35 = \$ 612.50[/tex]

Then, after 52 weeks: [tex]\$612.50 \times 52=\$ 31,850[/tex]

So, with the first plan, you make $31,850 + $1,500 = $33,350.

Just $32,000 per year. It's a little bit better than the first situation.

$18.50 per hour.

So, per week would be: [tex]18.50 \times 35 = \$647.50[/tex]

After 52 weeks you make: [tex]\$647.50 \times 52=\$33,670[/tex]

So, with the third plan, you make $33,670.

$30,000 per year with a 5% bonus, which mean

[tex]30,000 + 0.05(30,000)=30,000+1,500=31,500[/tex]

So, with this plane you make $31,500 a year.

Therefore, as you can deduct, the best option is the third plan, $33,670 per year.

Answer: 24 meters.

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

[tex]P=2l+2w[/tex]

Where l is the lenght and w is the width.

The perimeter of the original rectangle  is 88 m, then:

[tex]88=2l+2w[/tex]      [EQUATION 1]

Where l is the length of the original rectangle

 You know that if the width were doubled and the length were increased by 12 m, the perimeter would be 152 m. Therefore the new length is:

[tex]l+12[/tex]

The new width is:

[tex]2w[/tex]

Susbtitute into the equation of the perimeter and solve for w:

[tex]152=2(l+12)+2(2w)\\4w=152-(2l+24)[/tex]

 [tex]w=\frac{128-2l}{4}[/tex]      [EQUATION 2]

Substitute the Equation 2 into Equation 1 and solve for the length, as you can see below:

[tex]88=2l+2(\frac{128-2l}{4})[/tex]

[tex]88=2l+2(\frac{128-2l}{4})\\88-2l=\frac{128-2l}{2}\\\\176-4l=128-2l\\176-128=4l-2l\\\frac{48}{2}=l\\\\24=l[/tex]

Therefore, the length of the original rectangle is 24 m.

Answer:

Length  of original rectangle = 24 m

Step-by-step explanation:

Perimeter of rectangle

P = 2(l + b)

l - length and b - width

It is given that,the perimeter of a rectangle is 88 m. If the width were doubled and the length were increased by 12 m, the perimeter would be 152 m

Perimeter of original rectangle = 88 m

2(l + b) = 88

l + b = 44

b = 44 - l

To find length and width

length l = l + 12  and width = 2(44 - l) then,

Perimeter = 152 m

we can write,

2( l + 12 + 2(44 - l)) = 152

l + 12 + 88 - 2l = 152/2 = 76

100 - l = 76

l = 100 - 76 = 24

Therefore length = 24 m

width = 44 - l = 44 - 24 - 20 m

Since we're dealing with the b value here, we are talking about an x axis reflection.

Answer:

B because it is close to 30

Step-by-step explanation:

Answer:

The correct answer is option A   17.8°

Step-by-step explanation:

From the figure attached with this answer,

We can see a perpendicular from B to side AC

To find BD

In triangle BDC, its angles are 30°, 60° and 90°

Therefore the sides are in the ratio 1 :√3 : 2

Here BC = 11

BD : DC : BC = 1 :√3 : 2 = 11√3/2 : 11/2 : 11

Therefore BD = 11/2

To find the value of  m<A

We have

Sin ∅ = Opposite side /Hypotenuse

AB = 18 and BD = 11/2

Sin A = BD/AB =(11/2)/18 = 11/36 = 0.3055

m<A = Sin⁻¹(0.3055) = 17.79 ≈ 17.8°

Therefore the correct answer is option A  17.8°
