Point P is on side AC of triangle ABC such that angle APB = angle ABP, and angle ABC - angle ACB = 39. Find angle PBC in degrees

Therefore, the nth term of the sequence is approximately 29.94.

Assuming that the sequence is formed by alternating between adding 1.5 and multiplying by a constant factor, the nth term can be calculated using the following formula:

nth term = [tex]5.5 * c^{((n-1)//2}) + 1.5 * ((n-1) % 2)[/tex]

Here "//" represents integer division, "%" represents the modulo operator, and c is the constant factor that multiplies each term.

Assuming that the constant factor is 1.5 and the sequence starts with the first term being 5.5, the first few terms of the sequence would be:

5.5, 7, 10.5, 16, 24.5, 37, 55.5, 83, 124.5, ...

Using the formula above, we can find the nth term for any given value of n. For example, the 10th term would be:

nth term = 5.5 * [tex]1.5^4[/tex]+ 1.5 * 1

= 5.5 * 5.0625 + 1.5

= 29.9375

Step-by-step explanation:

C(x) is the linear cost function: C(x) = $50x + $300

Where x denotes the number of things manufactured.

A function connects an input with an output. It is analogous to a machine with an input and an output. And the output is somehow related to the input. The standard manner of writing a function is f(x) "f(x) =... "

To find the linear cost function, we need to determine the slope of the cost function and the value of the y-intercept.

Given that 40 items cost $2,300 to produce, we can use this information to find the slope:

Slope = (Change in cost) / (Change in quantity)

Slope = (Total cost for 40 items - Fixed cost) / (40 items - 0 items)

Slope = ($2,300 - $300) / (40 - 0)

Slope = $2,000 / 40

Slope = $50 per item

The fixed cost of $300 represents the y-intercept of the cost function.

Therefore, the linear cost function C(x) is:

C(x) = $50x + $300

Where x represents the number of items produced.

Given that, m∠1 = (5x)°, m∠2 = (4x + 10)° and m∠3 = (10x − 5)°.

Angle sum property of a triangle is m∠1 + m∠2 + m∠3 = 180°

Here, (5x)° + (4x + 10)°  + (10x − 5)° = 180°

(5x + 4x + 10  + 10x − 5) = 180

(19x + 10 − 5) = 180

(19x + 5) = 180

19x = 180 - 5

19x = 175

x = 175/19

x ≈ 9.21

Then, substitute the value of x in (10x − 5)°,

The probability of there being exactly 10 days with exactly 3 birthdays out of a group of 100 people is extremely low, approximately 4.63 x [tex]10^{-37}[/tex]

To answer this question, we need to use the concept of probability. The probability of an event happening is the number of desired outcomes divided by the total number of possible outcomes.
In this case, the desired outcome is that there are exactly 10 days with exactly 3 birthdays. To calculate this probability, we need to consider the total number of ways that 100 people can be distributed across 365 days.
There are a total of [tex]365^{100}[/tex] possible ways to distribute birthdays. However, not all of these possibilities are valid because we are looking for exactly 10 days with exactly 3 birthdays.
We can use the formula for combinations to calculate the number of ways that 10 days can be selected out of 365. This is given by:
C(365, 10) = 3.535 x [tex]10^{21}[/tex]
For each of these combinations, we need to calculate the number of ways that exactly 3 people can be assigned to each of the 10 days. This is given by:
[tex]C(100, 3)^{10}[/tex] = 7.917 x [tex]10^{61}[/tex]
The total number of valid outcomes is the product of these two values:
3.535 x [tex]10^{21}[/tex] x 7.917 x [tex]10^{61}[/tex] = 2.798 x [tex]10^{83}[/tex]

Answer:

140

Step-by-step explanation:

7/20 = 0.35 = 35% of the 20 players made all five baskets.

If this trend holds up, then we should expect 35% of the 400 people to make all five baskets.

35% of 400 = 0.35*400 = 140

We expect about 140 people will make all five baskets.

Note how 140/400 = 0.35 = 35%

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

Through another alternative method, we can solve like this

7/20 = x/400

7*400 = 20*x ... cross multiply

2800 = 20x

20x = 2800

x = 2800/20 ... dividing both sides by 20

x = 140 which is the same result as before

it's going to be 150 baskets made

A.  The negation of the given statement is "There exists an x such that for all y, y is not greater than x".

B. The negation of the given statement is "For all integers n, 2n² - 5n + 2 is not equal to 0".

E. the statement is true by contraposition.

Integers are a type of number that includes all positive whole numbers (1, 2, 3, ...), zero (0), and negative whole numbers (-1, -2, -3, ...). In mathematical notation, the set of integers is denoted by the symbol Z.

a. The given statement is ∀x ∃y, y > x. Its negation is ¬(∀x ∃y, y > x), which is equivalent to ∃x ¬(∃y, y > x). By De Morgan's law, we can simplify this as ∃x ∀y, ¬(y > x). Therefore, the negation of the given statement is "There exists an x such that for all y, y is not greater than x".

b. The given statement is ∃n ∈ Z, 2n² − 5n + 2 = 0. Its negation is ¬(∃n ∈ Z, 2n² − 5n + 2 = 0), which is equivalent to ∀n ∈ Z, 2n² − 5n + 2 ≠ 0. Therefore, the negation of the given statement is "For all integers n, 2n² - 5n + 2 is not equal to 0".

c. To disprove the statement, we need to find a counterexample where the statement is false. Let x = 10. Then, for any y greater than 10, y is also greater than 6. Therefore, the statement is true for this choice of x, and hence the statement is true.

d. To prove the statement, we can use proof by contradiction. Assume that there exists a real number n such that n ≤ 7 and n > 9. This is a contradiction, and hence our assumption must be false. Therefore, the statement "If n is a real number, then either n > 7 or n ≤ 9" is true.

e. To prove by contraposition, we need to show that if one of the integers is even, then the product of the integers is even. Let's assume that one of the integers is even, say a = 2k. Then, the other integer can be odd or even, but in either case, the product of the integers will be even. Therefore, the statement is true by contraposition.

Answer:

  (c)  $217,071.56

Step-by-step explanation:

You want the value of an ordinary annuity after 10 years when payments of $4000 are made quarterly and the interest is 6%.

A suitable financial calculator can tell you the value of 40 quarterly payments that earn an 6% annual rate will be $217,071.58.

Or, you can use the ordinary annuity formula to find the future value:

  FV = P(n/r)((1 +r/n)^(nt) -1)

  FV = 4000(4/0.06)((1 +0.06/4)^(4·10) -1) = 4000/0.015(1.015^40 -1)

  FV ≈ 217,071.575645 ≈ 217,071.58

The future value of the annuity in 10 years is $217,071.58.

The discrepancy in the offered answer choice(s) appears not to be due to rounding of the final value. Perhaps there was some unfortunate rounding of intermediate values when it was calculated.

We conclude that there is a significant difference between the standard deviations of the base and modified product's length.

To test if there is a difference between the standard deviations of the two populations, we can use the F-test.

a) The critical values for the F-distribution with 11 and 11 degrees of freedom at α = 0.01 are 0.250 and 4.025 (found using a statistical table or calculator).

b) The test statistic for the F-test is calculated as:

[tex]F = s1^2 / s2^2[/tex]

where s1 and s2 are the sample standard deviations of the base product and the modified product, respectively.

s1 = 7 cm (given in the problem)

s2 = 3 cm (calculated from the sample data)

Thus, the test statistic is:

F = ([tex]7^2[/tex]) / ([tex]3^2[/tex]) = 16.33

c) To determine if there is a difference between the standard deviations, we compare the test statistic to the critical values. Since our test statistic (16.33) is greater than the critical value of 4.025, we reject the null hypothesis that the standard deviations are equal. Therefore, we conclude that there is a significant difference between the standard deviations of the base and modified product's length.
