The Cardinal number of the set of all solutions to x²=100 is 2.

What is Number system?

A number system is defined as a system of writing to express numbers.

Cardinal numbers are natural numbers or positive integers. The smallest cardinal number is 1.

We have to find the Cardinal number of the set of all solutions to  x²=100

To find the solution of the equation we have to take square root on both the sides' x=10, -10

The set of solutions will be {-10, 10}

It has two terms. Hence cardinal number is 2.

Hence, the Cardinal number of the set of all solutions to x²=100 is 2.

What is the theoretical probability of a 5 or 6?
_Answer as a fraction. (5 pts)
What is the experimental probability 5 or 6?
Answer as a fraction. (5 pts)

Answers

Answers:

Theoretical probability of 5 or 6 is 1/3

Experimental probability of 5 or 6 is 9/25

======================================================

Explanation:

For the theoretical probability, we ignore the table of values. We assume the cube will land on any of the 6 sides with equal probability.

So landing on any given side has probability 1/6. Landing on 5 or 6 has probability 2*(1/6) = 2/6 = 1/3.

---------

For the experimental probability, we use the table. We see that '5' shows up twice, and '6' shows up seven times. In total, those values show up 2+7 = 9 times out of 25 total.

So that's how I got 9/25.

Answers

Answer:

90 cups

Step-by-step explanation:

First, let's calculate how much cups of sugar we need for 1 batch of chocolate chip.

45 / 4 = 11.25

So, now we know that we need 11.25 cups of sugar to make 1 batch of chocolate chip.

Therefore, we know we need 90 cups of sugar for 8 batches because

11.25 * 8 = 90

The area of the base is 1·/4ft^2 . What is the volume of the cube?

Answers

Answer:

1/8 ft^3

Step-by-step explanation:

The cube has equal sides. So u square root the base area and u get 1/2 ft. The length, width and height are all 1/2. So u cube the 1/2. Your final answer would be 1/8 ft^3.

Answer:

V = 1/8 ft³

Step-by-step explanation:

Area of the base = 1/4 ft² = l²

l² = 1/(2)² ft²

l = 1/2 ft

V = l³

= (1/2 ft)³

= 1/2³ ft³

= 1/8 ft³

A map has a scale of
2 in. = 18 mi. If you measured the distance between two cities to
be 16 in. on the map, how many miles would it actually be?

Answers

Answer:

it would be 144 miles

Step-by-step explanation:

We start by a ratio of map to mile =      2:18

if we see that the map distance is 16,   16:?

We divide 16 by 2 to get 8, so we enlarge the 2, 8 times, and we get 16

the 18, also has to be enlarged, so 18x8 = 144

It will be 144 miles

Given :

Length of parade , [tex]L = 3\ miles=3\times 5280\ miles = 15840\ miles[/tex] .

Breadth of parade , [tex]B=2\times 15=30\ ft[/tex] .

Find the focus and directrix of the parabola y= 1/2 (x+2)^2 - 3 A. The focus is at (–2,–2) and the directrix is at y = –4. B. The focus is at (–2,–3) and the directrix is at y = –5. C.The focus is at (–2,–2 1/2) and the directrix is at y = –3 1/2. D. The focus is at (–2,–1 1/2) and the directrix is at y = –2 1/2.

Answers

Answer:

C. The focus is at [tex](-2,-2 \frac{1}{2})[/tex] and the directrix is at [tex]y = -3\frac{1}2.[/tex]

Step-by-step explanation:

First of all, let us learn about the formula to find Focus and Directrix from the standard equation of a parabola.

Standard form of a parabola is given as:

[tex](x - h)^2 = 4p (y - k)[/tex]

where the focus is [tex](h, k + p)[/tex] and

the directrix is [tex]y = k - p[/tex]

Now, we are given the equation of parabola as:

[tex]y= \dfrac{1}2 (x+2)^2 - 3[/tex]

Let us try to convert it to standard form:

[tex]\Rightarrow y+3= \dfrac{1}2 (x+2)^2 \\\Rightarrow 2(y+3)= (x+2)^2 \\\Rightarrow (x+2)^2 = 2(y+3)\\\Rightarrow (x+2)^2 = 4\times \frac{1}{2}(y+3)[/tex]

Comparing the above with standard equation of parabola [tex](x - h)^2 = 4p (y - k)[/tex]:

[tex]h = -2, p = \frac{1}{2}, k = -3[/tex]

So, Focus is at [tex](h, k + p)[/tex]

[tex]k + p = -3+\frac{1}{2} = -2\frac{1}{2}[/tex]

Focus is at [tex](-2, -1\frac{1}2)[/tex].

Equation of directrix:

[tex]y = k - p=-3-\frac{1}{2}\\\Rightarrow y = -3\frac{1}{2}[/tex]

Also, please refer to the attached image for the diagram of given parabola, focus and directrix.

So, the answer is:

C. The focus is at [tex](-2,-2 \frac{1}{2})[/tex] and the directrix is at [tex]y = -3\frac{1}2.[/tex]

A driver education course
costs $45 but saves those
under 25 years old 10% of their annual insurance premiums until they are 25. Dan has just
turned 18, and his insurance is $100 per month.

1. When will the amount saved from insurance equal the price of the course?
2. Including the cost of the course, when Dan turns 25, how much will he have saved?

Answers

Answer:

after 4.5 months (or 5)$795

Step-by-step explanation:

10% of $100 per month is $10 per month.

1. By saving $10 per month on insurance cost, Dan's savings after 4.5 months will be equal to the $45 cost of his course. (If billing is monthly, he won't experience any net gain from the course until the 5th insurance payment--after 5 months.)

__

2. In 7 years, the savings on insurance costs will total ...

  (7 years)×(12 months/year)×($10 /month) = $840

His cost for the course is $45, so his net saving is ...

  $840 -45 = $795 . . . net saving by age 25
