736 / 365 = 2R6

So even if the first 365 students all have different birthdays, and the next 365 students also all have different birthdays, then there are 2 students for every birthday.  The last 6 students therefore share a birthday with at least 2 other students.  So there are at least 3 students who share a birthday.

Yes, we can prove that at least three students have a birthday on the same day of the year.

What is algebra?

Algebra is the study of mathematical symbols and the rules for manipulating these symbols in formulas.

We have,

Total number of students = 736

So,

In a year there are 365 days.

And we have 736 students,

So,

Two students have birthday on same day = 365 × 2 = 730

NOw,

Students left = 736 - 730 = 6

So,

These 6 Students  share birthday with othe 6 Students .

So, yes there are at least three students who have a birthday on the same day of the year

Answer:

f(2) = 0 and f(6) = -4

Step-by-step explanation:

First, find f(x) when x = 2

Plug in 2 as x in the function:

f(x) = -(x - 2)​

f(2) = -(2 - 2)

f(2) = -(0)

f(2) = 0

Next, find f(x) when x = 6. Plug in 6 as x in the function:

f(x) = -(x - 2)​

f(6) = -(6 - 2)

f(6) = -(4)

f(6) = -4

So, f(2) = 0 and f(6) = -4

The simplified form of -20/2(7 2/3) is -230/3.

To solve the expression -20/2(7 2/3), we need to follow the order of operations, which states that we should perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.

First, let's convert the mixed number 7 2/3 to an improper fraction.

7 2/3 = (7 * 3 + 2) / 3 = 23/3

Now, let's substitute the value back into the expression:

-20/2 * (23/3)

Next, we simplify the multiplication:

-10 * (23/3)

To multiply a fraction by a whole number, we multiply the numerator by the whole number:

-10 * 23 / 3

Now, we perform the multiplication:

-230 / 3

Therefore, the simplified form of -20/2(7 2/3) is -230/3.

The annual premium represents the periodic payment that the insured is expected to pay to the insurance company for an insurance policy contract.

Using the table which gives the annual premium per $1000; the premium paid annually by the 33-year-old male is $594.75

The total annual premium = $75000

Using the data in the table :

Annual premium per $1000 of coverage for a 33-year-old male with a 20 - years life insurance policy = $7.93

The annual premium for $75,000 ;

Premium per $1000 × ($75000/$1000)

Answer:

7.3%

Step-by-step explanation:

Percent error can be calculated using the formula:

percent error = (|estimated value - actual value| / actual value) x 100

Plugging in the values for the given scenario:

percent error = (|75 - 82| / 82) x 100 = 7.32 x 100 = 732%

Rounding to the nearest tenth:

percent error = 732% = 7.3%

Answer:

To determine the winning strategy for the first player in this game, we can start by looking at small values of n and see if we can identify a pattern.

For n = 1, the first player must remove the only token, so they win.

For n = 2, the first player can remove one token and win, or they can remove two tokens and lose.

For n = 3, the first player can remove one token, leaving two tokens for the second player, who will then be forced to lose.

For n = 4, the first player can remove two tokens, leaving two tokens for the second player, who will then be forced to lose.

Based on these observations, it seems that if n is a multiple of 3, the first player has a winning strategy. To see why this is the case, we can use mathematical induction.

Assume that if n is a multiple of 3, the first player has a winning strategy. We want to show that if n+1 is a multiple of 3, the first player also has a winning strategy.

If n+1 is a multiple of 3, we can write n+1 = 3k+1 for some integer k.

If the first player removes one token, there will be n tokens left, and the second player will be in a losing position by our assumption.

If the first player removes two tokens, there will be n-1 tokens left. If the second player removes one token, there will be n-2 tokens left, and the first player will be in a winning position by our assumption. If the second player removes two tokens, there will be n-3 tokens left, and the first player can remove one token, leaving n-4 tokens for the second player. At this point, the second player will be in a losing position by our assumption.

Therefore, we have shown that if n is a multiple of 3, the first player has a winning strategy, and this strategy can be described as follows:

If n is already a multiple of 3, remove one token.

If n is not a multiple of 3, remove two tokens if possible, otherwise remove one token.

We can also observe that if n is not a multiple of 3, the second player has a winning strategy.

Answer: To find the derivative of the function h(x), we can use the quotient rule, which states that if f(x) = u(x) / v(x), then f'(x) = [v(x)u'(x) - u(x)v'(x)] / [v(x)]^2.

Using this rule, we can find the derivative of h(x) as follows:

h(x) = (x + 2) / (x - 2)

h'(x) = [(x - 2)(1) - (x + 2)(1)] / (x - 2)^2 // apply the quotient rule and differentiate numerator and denominator

h'(x) = (-2 - 2x) / (x - 2)^2

Therefore, the derivative of h(x) is h'(x) = (-2 - 2x) / (x - 2)^2.

The actual distance is 160 miles.

A representative fraction is a scale that can be used to either increase or decrease the size of length of a given object. It can be expressed as:

Representative fraction = length on drawing/ actual length

Given that the map of the river has a scale of 3 inches: 8 miles. Let the actual distance be represented by x. It can be deduced that;

3 inches/ 8 miles = 60 inches/ x

make x the subject of the formula, we have;

x = (8 miles * 60 inches)/ 3 inches

  = 8 miles * 20

  = 160 miles

x = 160 miles

Therefore, the actual distance is 160 miles.

Answer:

x=4 and y=8

Step-by-step explanation:

p-value is a measure of the probability that an observed difference could have occurred just by random chance.

Answer:

1/8

Step-by-step explanation:

We want to find the slope of any line that is perpendicular to the line passing through the points M(-1, 5) and N(0, -3).

Recall that the slopes of perpendicular lines are negative reciprocals of each other. In other words, the slope of any line perpendicular to line MN must be the negative reciprocal of the slope of line MN.

Find the slope of MN using the slope formula:

\(\displaystyle m_{MN} = \frac{\Delta y}{\Delta x} = \frac{(-3)-(5)}{(0)-(-1)} = \frac{-8}{1}=-8\)

So, the slope of line MN is -8.

The slope of any line perpendicular to MN must be its negative reciprocal. The negative reciprocal of -8 is 1/8.

Therefore, the slope of any line perpendicular to the line passing through the points M(-1, 5) and N(0, -3) is 1/8.
