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

that's the quadratic formula:)

Step-by-step explanation:

Answer:

You could make 4,641,000 different choices.

Step-by-step explanation:

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices could I make?

3 cards from a set of 52(number of cards on a standard deck).

4 Pokemon cards from a set of 10. So

[tex]T = C_{52,3}*C_{10,4} = \frac{52!}{3!49!}*\frac{10!}{4!6!} = 22100*210 = 4641000[/tex]

You could make 4,641,000 different choices.

Step-by-step explanation:

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to [tex]b=2\sqrt{2}[/tex].

In a 45-45-90 triangle, the hypotenuse is equal to [tex]x\sqrt{2}[/tex] this means in order to find missing side length a, we have to multiply [tex](2\sqrt{2})(\sqrt{2})[/tex] this will give us 4

so the missing side lengths are, [tex]b=2\sqrt{2}[/tex] and [tex]a=4[/tex]

Answer: B = 2 (Square root of 2) A = 4

Explanation: This is an isosceles triangle so the legs will be the same. To get the hypotenuse I simply just multiplied one leg by the square root of 2 and two square roots of the same number multiply the whole number by whatever number is in the square root (so in this case it's multiplying 2 by 2)

Answer:

b. This is a good project if the probability of expropriation is smaller than .33.

Step-by-step explanation:

a) Data and Calculations:

Cash inflows per year going forever = $3 million

Cost of project = $10 million

Discount rate for the project = 15%

The present of a perpetuity = Cash inflow/Discount rate

= $3/0.15 million

= $20 million

NPV = $10 million ($20 - $10 million)

b) The probability of expropriation indicates that the government of Bolivia may likely take over the project after the initial investment had been made.  This will cause the investor to lose her investments.  If the probability of the expropriation taking place is equal to 0.33, the investor may recover the cost of investment without making any profit in three years' time.  But if the probability of expropriation happening is less than 0.33, the investor could recover enough to cover the investment cost.

The length of the building site is 75 meters.

To calculate the length of the rectangular plot of land, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

In this case, the width is given as 60 m, and the perimeter is given as 270 m. We can substitute these values into the equation and solve for the length.

270 = 2 * (Length + 60)

Dividing both sides of the equation by 2 gives:

135 = Length + 60

Subtracting 60 from both sides of the equation gives:

Length = 135 - 60

Length = 75

It's important to note that the length of the building site is specific to this particular rectangular plot of land with a given width and perimeter. If the width or perimeter were to change, the length would also change accordingly. Additionally, this calculation assumes that the shape of the plot is a rectangle and that the perimeter only includes the sides of the plot, not any internal structures or obstacles.

Answer:

12.5%*7=87.5%

4000*7=28000

28000

Answer:

28,000

Step-by-step explanation:

Since 4,000 is 12.5%, you can divide 87.5/12.5 to see how many times 12.5 goes into 87.5, which is 7 times. so then since you need to find the value of how much 87.5% is, then you can multiply 4,000 by 7 since 7 is 87.5 percent, leaving us with 28000

Answer:

76

Step-by-step explanation:

I rewrote the question so I wouldn't have to keep going back to the picture.

A poll asked 1000 adults who own smartphones where they put their smartphone while sleeping. The following two-way table of relative frequencies shows the data collected on age and smartphone habits. Of the adults polled, 200 were 65 or older.

How many of the adults polled that were 65 or older sleep with their smartphone within reach?

---------------------------------------------------------------------------------

I bet if I called this a two- way table of "percentages, written as decimals", it would make more sense.

Total number of adults 65 and older = 200. The 0.38 of them that sleep with their phone in reach = 38% of them. Multiply 200 x 0.38 = 76

To check the math, 200 x 0.62 = 124, and 124 + 76 = 200.

Answer:

A = 48°

b = 13.5

c = 20.2

Step-by-step explanation:

✔️A = 180° - (90° + 42°) (sum of triangle)

A = 48°

✔️To find b and c, apply trigonometric function.

Reference angle = 42°

Opposite = b

Hypotenuse = c

Adjacent = 15

✅Apply TOA to find b:

Tan 42 = Opp/Adj

Tan 42 = b/15

15 × Tan 42 = b

13.5060607 = b

b = 13.5 (nearest tenth)

✅Apply CAH to find c:

Cos 42 = Adj/Hyp

Cos 42 = 15/c

c × Cos 42 = 15

c = 15/Cos 42

c = 20.1844909

c = 20.2 (nearest tenth)
