Answer:

79

Step-by-step explanation:

Let's say that N is the number of cards.

So the first step is N+5, because dan bought 5 new cards.

Next his dog ate half the collection, so the 2nd piece of the problem is [tex]\frac{N+5}{2}[/tex]

The last step is to now make it an equation. Because there are now 46 cards left, [tex]\frac{N+5}{2}[/tex]=42.

Now solve for N which is N+5=84=> N=79

Answer:

a) There is an integer a such that  [tex]\frac{a-1}{a}[/tex] is  an integer

b) False

Step-by-step explanation:

Statement : ∀a ∈ Z,    (a − 1) a is not an integer

A) The correct negation will be :

There is an integer a such that  [tex]\frac{a-1}{a}[/tex] is  an integer

B) The Given statement is FALSE because

when we assume the value of a = 1

( a - 1 ) / a = (1 - 1 ) / 1 = 0   ;  which is an integer

Explanation:

Garment factory: workers may get paid by the number of pieces they complete.

__

Wood chopping: the worker gets paid by the number of cords of wood they produce, not by how long it takes.

__

Haircut -- the cost is the same (for the same type haircut) even if more time is spent

____

The above are instances where an individual worker gets paid by the piece they produce. There are numerous instances of companies getting paid by the job, regardless of the length of time or the quantity of materials required to do the job.

Lawn mowing -- the price is fixed each time the crew mows the lawn

Oil Change -- the cost of changing the oil in the car is not dependent on the time it takes or the amount of oil used

Car wash -- a fixed price is paid each time (at an automatic car wash)

Answer:

(a)

[tex]Small = 28[/tex]

[tex]Large = 42[/tex]

(b)

[tex]Ratio = 14 : 25[/tex]

Step-by-step explanation:

Given

[tex]L = Large\\ S = Small[/tex]

[tex]S : L = 2 : 3[/tex]

[tex]Total = 70[/tex]

Solving (a): Number of each set.

The small set is calculated as:

[tex]Small = \frac{S}{S + T} * Total[/tex]

[tex]Small = \frac{2}{2+3} * 70[/tex]

[tex]Small = \frac{2}{5} * 70[/tex]

[tex]Small = 0.4 * 70[/tex]

[tex]Small = 28[/tex]

Using complement rule.

[tex]Large = Total - Small[/tex]

[tex]Large = 70 - 28[/tex]

[tex]Large = 42[/tex]

Solving (b): Increase large by 8.

The ratio is then calculated as:

[tex]Ratio = Small : Large + 8[/tex]

[tex]Ratio = 28 : 42 + 8[/tex]

[tex]Ratio = 28 : 50[/tex]

Divide by 2

[tex]Ratio = 14 : 25[/tex]

Answer:

10 units is the answer.

Step-by-step explanation:

points are (-3,2) and (-9,-6)

Pythagorean theorem can be written as,

[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(-9-(-3))^2 + (-6-2)^2}\\\\d=\sqrt{(-6)^2+(-8)^2} \\\\d=\sqrt{36+64} \\\\d=\sqrt{100} \\\\d=10[/tex]

∴ distance between the points = 10 units

Answer:

D. 16

Step-by-step explanation:

A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results:

MACHINE MEASUREMENTS

#2 16 25 18 25

#3 23 24 23 22

Answer:

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Binomial approximation to normal.

The binomial probability distribution has parameters n, p and q.

If

[tex]np \geq 5[/tex] and [tex]nq \geq 5[/tex], you can use the normal approximation.

1. n = 24, p = 0.85, q = 0.15

[tex]np = 24*0.85 = 20.4 > 5[/tex]

[tex]nq = 24*0.15 = 3.6 < 5[/tex]

So no.

2. n = 15, p = 0.70, q = 0.30

[tex]np = 15*0.7 = 10.5 > 5[/tex]

[tex]nq = 15*0.3 = 4.5 < 5[/tex]

So no.

3. n = 18, p = 0.90, q = 0.10

[tex]np = 18*0.9 = 16.2 > 5[/tex]

[tex]nq = 18*0.1 = 1.8 < 5[/tex]

No

4. n = 20, p = 0.65, q = 0.35

[tex]np = 20*0.65 = 13 > 5[/tex]

[tex]nq = 20*0.35 = 7 > 5[/tex]

Yes

Answer:

C) 71

Step-by-step explanation:

To find the mean you must first add all the numbers:

68 + 70 + 76 + 71 + 70 = 355.

After that you divide the number you got by how many numbers are in the set.

There are five players so we divide the number by 5

355/5 = 71

Therefore, it is 71.

Answer:

15

Step-by-step explanation:

Since we're working with fractions, and the thirty ounce bucket is equivalent to 30/30. In order to make this easier, let's use the denominator of 30 for all of the fractions. Now that we've made them all equal, turning 1/10 to 3/30, and 2/5 to 12/30, let's add. 12 + 3 is 15, and 15/30 is half of 30/30. There was 15 ounces, or 1/2 of the tub, left.

Step-by-step explanation:

The length of the altitude of the equilateral triangle is a√3/4 units.

Given is to find the length of the altitude of the equilateral triangle.

An equilateral triangle is a triangle whose all sides are equal. All the angles of a given equilateral triangle are 60 degrees.

The length of the altitude of the equilateral triangle can be found out using the Pythagoras theorem.

Draw a median from one vertex on the opposite side to that vertex and apply Pythagoras theorem to one of the right triangle.

We can find the length of the altitude to be -

L = a√3/4

Therefore, the length of the altitude of the equilateral triangle is a√3/4 units.

Answer:

  B.  (4, 5π/3)

Step-by-step explanation:

If you sketch the location of the point, you find the coordinates correspond to the side lengths of a 30°-60°-90° "special" triangle. The reference angle is 60°, or π/3 radians, and the magnitude of the vector is twice the short dimension, so is 2×2 = 4.

The polar coordinates are (4, 5π/3).

Answer:

The perimeter of the resulting image is 13 centimeters

Step-by-step explanation:

we know that

Rotation, reflection, and translation are transformations that do not produce changes in the dimensions of the figure, while dilation is a transformation that does affect the dimensions of the figure.

In this problem, we have rotation and reflection

therefore

The perimeter of the resulting figure is the same as the original figure
