Answer:

The distance between the two points (6, 9) and (−3, 7) can be found using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we get:

d = √((-3 - 6)^2 + (7 - 9)^2)

d = √((-9)^2 + (-2)^2)

d = √(81 + 4)

d = √85

So the distance between the two points in simplest radical form is √85.

Answer:5

Step-by-step explanation:

When only non-negative integer powers or only positive integer exponents of a variable are used in a function, the function is called a polynomial. The enclosure's largest area is 562500 square feet.

When a variable in an equation like the quadratic equation, cubic equation, etc. has only non-negative integer powers or only positive integer exponents, the function is said to be polynomial.

One polynomial with an exponent of 1 is 2x+5, for instance.

As stated, the function is:

V(x) = 1500x - x^2

Differentiate

V'(x) = 1500 -2x

Set to 0

2x = 1500

Multiply by 2

x = 750

Put x = 750 in place of V(x) = 1500x - x2.

V(x) = 1500*750 - 750^^2

Evaluate

V(x) = 562500

Consequently, the enclosure's largest possible area is 562500 square feet.

The mean of this test is 35.

What is the Mean?

The mean is a measure of central tendency that represents the average of a set of data. It is calculated by summing all the values in a dataset and then dividing the sum by the number of values in the dataset. It is also known as the arithmetic mean or simply the average.

Let X be the mean of the test.

We know that a score of 29 falls two standard deviations below the mean, which means that X- 2 * standard deviation = 29.

Similarly, we know that a score of 41 falls two standard deviations above the mean, which means that X+ 2 * standard deviation = 41.

The mean of a normal distribution is the sum of the two values divided by two.

So:

Mean = (29+41)/2 = 70/2 = 35

Answer: 35

Step-by-step explanation:

Answer: She must save €230 - €209.8 = €20.2 more to buy the watch.

Step-by-step explanation:

Tamsin has saved 286 * €0.50 = €143 from 50 cent coins.

The remaining coins are 620 - 286 = 334 which are 20 cent coins

So the total amount she has saved from 20 cent coins is 334 * €0.20 = €66.8

Therefore, the total amount she has saved is €143 + €66.8 = €209.8

So she must save €230 - €209.8 = €20.2 more to buy the watch.

The two options that represent the equation of the circle are:

x² + (y – 3)² = 36

x² + (y + 8)² = 36

Options A and E are the correct answer.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

The equation of a circle is (x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius.

Now,

Diameter of the circle = 12 units

This means,

Radius = 12/2 units = 6 units

Now,

Center of the circle = y-axis.

This means,

x = 0,

y = a

Center = (0, a)

Now,

The equation of the circle.

(x - 0)² + (y - a) = 6²

x² + (y - a)² = 36

Where a can be any number.

Thus,

The equation of the circle can be:

x² + (y – 3)² = 36

x² + (y + 8)² = 36

If Warren keeps up his saving pace, he will need to have $262144 saved by October 1st.

The difference between every two successive terms in an arithmetic series is always the same.  The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

given, Warren wanted to save money to purchase a new car. He started by saving​ $1 on the first of January. On the first of​ February, he saved ​$4. On the first of​ March, he saved ​$16

that means on the first day of each month he saves 4 times as much as he did on the first day of the previous month.

From the general formula of a geometric sequence

The nth term of a geometric sequence aₙ = arⁿ⁻¹

Where a = first term

r = ratio

in our case

a = 1

r = 4/1 = 4

Since October is the 10th month of the year

thus,

the money he will save in the month of October = ar⁹

the money he will save in the month of October = 1 * 4⁹

the money he will save in the month of October = 262144

Therefore, if Warren continues his savings​ pattern, he needs to save $262144 on the first day of ​October

Calculate the monthly interest rate: 18%/12 = 1.5%

Calculate the total number of payments: 5 years * 12 months/year = 60 payments

Use the formula for the present value of an annuity:

P = (R * (1 + r)^n) / (((1 + r)^n) - 1)

where P is the payment, R is the debt, r is the monthly interest rate, and n is the number of payments.

Plug in the values:

P = ($23,864 * (1 + 0.015)^60) / (((1 + 0.015)^60) - 1)

The probability of both of them being selected is 0.6, while the probability of at least one of them being picked is 0.95, and the probability of none of them being chosen is 0.05. Only one of them will be selected, with a probability of 0.4.

Probability is the measure of how likely an event is to occur in a given situation. It is expressed as a numerical value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The mathematical study of random occurrences is known as probability theory. It is concerned with the investigation of random variables and the development of models and hypotheses to explain their behavior. Probability theory is used to anticipate the results of random occurrences like the roll of a dice or the flip of a coin. It may also be used to predict the likelihood of a certain event, such as the chance that a stock will rise in value or that a patient would respond to a specific therapy.

i) The probability that both of them will be selected is 0.6 (80% x 75%).

ii) The probability that at least one of them will be selected is 0.95 (80% + 75% - (80% x 75%)).

iii) The probability that none of them will be selected is 0.05 (1 - (80% + 75% - (80% x 75%))).

iv) The probability that only one of them will be selected is 0.4 (80% + 75% - (2 x (80% x 75%))).

Probabilities are mathematical explanations of the likelihood that an event will occur or that a proposition is true.

The term "probability" is most commonly used to refer to the likelihood that a specific event (or group of events) will occur, either as a linear scale from 0 (impossibility) to 1 (certainty), or as a percentage between 0 and 100%. Statistics is the study of events subject to probability.

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty.

The likelihood or chance that a specific event will occur is represented by a probability. Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.

Answer:

Miles in 19.08 km =11.925 miles

You mis-typed the value asked for in the question in original screenshot. It is asking for 19.08km in the screenshot but you used 19.09 when you typed the question

Step-by-step explanation:

The relationship between miles and kilometers is linear

To determine how many miles there are in 1 kilometer divide the km value on the right by the corresponding mile value on the left

Take the first entry

18.2/29.12 = 0.625

So 1 km = 0.625 miles

The same operation with the other entries should give the same result of 0.625

Therefore number of miles in 19.08 (NOT 19.09 as you wrote in your question) = 0.625 x 19.08 = 11.925 miles

Answer:

11.8619761

Step-by-step explanation:

multiply the value in kilometers by the conversion factor '0.62137119223677'.

So, 19.09 kilometers = 19.09 × 0.62137119223677 = 11.8619760598 miles.

Answer:

Question 1  : 0.44

Question 2: 0.853

Step-by-step explanation:

We should use combinatorics to solve this problem

Combinations

The number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed

The formula for finding the number of ways you can pick r items from a set of n items where duplicates are eliminated is given by the combinations formula:

[tex]C(n,r) = \dfrac{n!}{( r! (n - r)! )}[/tex]

where the ! stands for the factorial of the number

Let's take simple example to illustrate this

Suppose we have 3 books labeled A, B. C and we are asked to randomly pick 2 books in one shot. There are 3 possible picks:

AB, AC, BC

Note that though there are six possible arrangements of 2 items from a set of 3, we have to eliminate duplicates because AB is the same as BA.

In the above case, r = 2, n = 3 so using the formula we get

[tex]C(3,2) = \dfrac{3!}{( 2! (3 - 2)! )}\\\\= \dfrac{3!}{2! \times 1! }\\\\\\= \dfrac{3 \times 2 \times 1}{(2 \times 1)(1)}\\\\\\= 3\\\\[/tex]

Now to the actual problem

There are a total of 18 students in the class

Number of ways of picking 3 students is
[tex]C(18,3) = \dfrac{18!}{( 3! (18 - 3)! )}\\\\= \dfrac{18!}{3! \times 15! }\\\\\\=816[/tex]

So there are 816 possible ways to pick 3 students from 18 students

There are calculators to perform this gruesome task so I will omit the actual steps and just show the result

Let's consider the first question
Out of the 3 students picked 2 are girls. That means the other one is a boy

Number of ways of picking 2 girls out of 10 is C(10, 2)

C(10, 2) = 45

Then we have to consider the lone boy. Number of ways of picking 1 boy out of 8 is

C(8, 1) = 8

Total number of ways of picking 2 girls and 1 boy

= 45 x 8 = 360

Therefore P(2 girls, 1 boy) :

[tex]\dfrac{360}{816} = 0.44[/tex]

Second question
To find the number of ways that at least 1 boy can appear in the group is the sum of the number of ways 1, 2 or 3 boys can appear in the group.

Rather than do this, let's approach it in a easier fashion

The probability of at least 1 boy appearing in the group is the complement of no boys on the group, i.e. all volunteers are girls

Number of ways of selecting a volunteer group of all 3 girls:

C(10, 3) = 120

P(no boys in group) = P(all 3 girls in group)
[tex]=\dfrac{120}{816} = 0.147[/tex]

Therefore P(at least 1 boy) = 1 - P(no boys)

= 1-0.147

= 0.853

Maria will need approximately 2209.6 square cm of paper to cover the entire container.

The formula for the surface area of a cylinder is A = 2πr² + 2πrh, where r is the radius and h is the height of the cylinder.

To find the surface area of the container, we can plug in the given values for r = 11 and h = 21:

A = 2π(11²) + 2π(11)(21)

A = 2π(121) + 2π(231)

A = 242π + 462π

A = 704π

We can approximate π as 3.14, then

A ≈ 704 × 3.14
