Answer:

(-7, 5) is correct.

Step-by-step explanation:

[tex]2x + 3y = 1[/tex]

[tex] - 2x - y = 9[/tex]

Add these two equations, and then solve for y.

[tex]2y = 10[/tex]

[tex]y = 5[/tex]

Substitute this value of y into 2x + 3y = 1, and solve for x.

[tex]2x + 3(5) = 1[/tex]

[tex]2x + 15 = 1[/tex]

[tex]2x = - 14[/tex]

[tex]x = - 7[/tex]

So (-7, 5) is the correct solution.

Step-by-step explanation:

probabilities are always

desired cases / totally possible cases

24 cans in total, 4 of them are diet, therefore 20 of them are regular.

2 cans are picked.

for the first can

the probability to pick a diet can is

4/24 = 1/6

the probability to pick a regular is

20/24 = 5/6

a)

to pick 2 diets, the first one has to be diet.

that leaves 23 cans with 3 being diet.

so, the probability for the second can being diet too is

3/23.

as combined event the probability to pull 2 diet cans is

1/6 × 3/23 = 1/2 × 1/23 = 1/46 = 0.02173913...

≈ 0.0217

b)

now the same for picking 2 regular cans.

the first one has to be regular :

5/6

that leaves for the second one 23 cans and 19 of them regular

19/23

combined this gives the probability

5/6 × 19/23 = 95/138 = 0.688405797...

≈ 0.6884

this is not unusual.

what would be considered "usual" or "unusual" ?

c)

one of them is diet, and one of them is regular.

the simple answer ?

it is the only other option, when the cans are not of the same type. it is the opposite of the sum of a) and b).

so, it is

1 - 0.688405797... - 0.02173913 = 0.289855072...

≈ 0.2899

but what to do, if we want to calculate it directly ?

it is the case that either

1. the first can is diet and the second can is regular,

or

2. the first can is regular and the second can is diet.

case 1.

the first can is diet = 1/6

leaving 23 cans with 20 being regular

the second can being regular = 20/23

together

1/6 × 20/23 = 1/3 × 10/23 = 10/69 = 0.144927536...

case 2.

the first can is regular = 5/6

leaving 23 cans with 4 diets.

the second can being diet = 4/23

together

5/6 × 4/23 = 5/3 × 2/23 = 10/69 = 0.144927536...

in an "exclusive or" situation we can add the probabilities.

so, the probability of having exactly one can diet and exactly one can regular is

0.144927536... + 0.144927536... = 0.289855072...

≈ 0.2899

ANSWER

0.01175 metres

EXPLANATION

We want to find how many metres are in 11.75 millimetres.

There are 1000 millimeters in 1 meter:

We will simply divide 11.75 milimetres by 1000

1000 millimetres = 1 metre

The critical value (tα/2) for a 95% confidence interval for the sample size 15 is 2.009.

We have to find the critical value tα/2 for 95% confidence interval, we are given the sample size.

First we will find the alpha value to get the critical value.

=100%-95%

=1-0.95

=0.05

α=0.05

α/2=0.05/2

α/2=0.025

degrees of freedom(df)= n-1=15-1=14

We will use degrees of freedom and α/2 values to find the critical value that is tα/2.

By using the t table we get the critical value  of tα/2=2.009.

Therefore, the critical value for 95% confidence interval with sample size of 15 is 2.009.

Note: The P(x) values for k = 0 and k = 1 are not actually zero, but they are small enough that they round to 0 when rounding to two decimal places.

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

Explanation:

I used a spreadsheet to compute the values in bold.

The specific command is called BINOMDIST

The template is BINOMDIST(k,n,p,0)

Let me know if you have any questions about how to use that function in a spreadsheet.

Also, I used the function called ROUND to round each value to 2 decimal places.

Example calculation

=ROUND(BINOMDIST(4,5,0.82,0),2)

This calculates the result of 0.41 and it corresponds to the value k = 4

Don't forget about the equal sign up front when computing these commands in the spreadsheet. Otherwise, it'll stay as text form.

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

If you want to use a TI83 or TI84 calculator, then press the button labeled "2nd". Then press the button labeled "VARS". Scroll down until you reach "binompdf".

The template is binompdf(n,p,k)

So for example, type in binompdf(5,0.82,4) to get the P(X) value for k = 4

If you aren't able to access a spreadsheet or a TI83/84 calculator, then search out "binomial distribution calculator" and there are plenty of free ones to pick from.

In my opinion, a spreadsheet is the best option since the given data is already in tabular form. Also, many real world situations and careers use spreadsheets everyday.

The vertices are P (-4, -5), L (1, -7), and K (-9, 8).

The vector is < -6,3 >.

Aim:

We need to find the image of the vertices when translating given vertices along the vector.

Explanation:

The translation vector <-6,3> means each point is being moved 6 units to the left and 3 units up.

For each vertex, we subtract 6 from each x value and add 3 to each y value.

Final answer:

A function that models the population of 400 birds decreasing at an annual rate of 6% is  [tex]f(x) = 400(1 - 0.06)^{t}[/tex] where t is the time period.

The Exponential decay formula aids in determining the quick decrease over time, i.e. the exponential decrease. The exponential decay formula is used to calculate population decay, half-life, radioactivity decay, and so on.

Its general form is f(x) = a (1 - r)ⁿ.

Where a = the initial amount

1 - r = decay factor and n = time period.

Given:

The initial population of birds, P = 400

Rate of decay, r = 6% = 0.06

Time = t years

By using the exponential decay formula,we get

[tex]f(x) = P (1 - r)^{t}[/tex]

[tex]f(x) = 400(1 - 0.06)^{t}[/tex]

Therefore, the function that models the population of 400 birds decreased at an annual rate of 6% is  [tex]f(x) = 400(1 - 0.06)^{t}[/tex].

The three consecutive integers according to the expression will be 6, 8, 10

In the given question, there is an expression stated that tells the condition for a sequence in which a number is represented by 'n'. The expression is the sum of three even integers whose sum is equal to four times the smallest of numbers.

The expression is n + (n + 2) + (n + 4) = 4n. We have to find out the values for each of the numbers.

Here, First Number = n

Second number = (n + 2)

Third Number = (n + 4)

Now, We will calculate the given expression to find out the value of n.

In a chemical reaction, atoms are neither CREATED nor DESTRUCTED. According to science, each side of the equation must contain the SAME amount of atoms.

You must place COEFFICIENTS in front of the chemical formulas in the equation in order to make it equal.

What does a chemical reaction always involve?

Only atoms from the reactants can end up in the products of a chemical reaction. No atoms are destroyed or made into new ones. When reactants come into touch with one another, the bonds between their atoms are broken, and the atoms then reorganize and form new bonds to create the products.

The value of the missing angles are; m∠ABC = 36° and m∠DBC = 41°

We are given that;

m∠ABD = 77°

Addition angle postulate states that the sum of two adjacent angle measures will equal the angle measure of the larger angle that they form together.

Now, by addition angle postulate, we can say that;

m∠ABC + m∠DBC = 77°

Now, we are given that;

m∠ABC = (5x - 4)°

m∠DBC = (5x + 1)°

Thus, by substitution property, we have;

(5x - 4)° + (5x + 1)° = 77

10x - 3 = 77

10x = 77 + 3

10x = 80
