Answer:

117°

Step-by-step explanation:

The angle in the bottom left is 180 - 101 = 79°; straight angle is supplementary

79° + 38° = 117°; 2 angles combined opposite from exterior angle is equal to the ext angle

Answer:

117º

Step-by-step explanation:

The angle measure of a line is 180º, so the measure of the angle next to the one with measure 101º is 180-101=79º.

The Exterior Angle Theorem says that an exterior angle (like x) is equal to the sum of the opposite interior angles. So, x=38+79=117º.

The value of c that satisfies the conclusion of the mean value theorem is c≈7.69.

The mean value theorem states that if a function f(x) is continuous on a closed interval [a,b] and differentiable on the open interval (a,b), then there exists at least one point c in (a,b) where the value of the derivative of f(x) is equal to the slope of the line connecting the endpoints of the interval, i.e., \(f'(c)=(f(b)-f(a))/(b-a).\)

Here, the function \(f(x)=x^(3/4)\) is continuous on the closed interval [0,16] and differentiable on the open interval (0,16), as the derivative of f(x) is \(f'(x)=(3/4)x^(-1/4)\), which is defined for all x in (0,16).

Therefore, we can apply the mean value theorem to this function on the interval [0,16].

To find the value of c that satisfies the conclusion of the mean value theorem, we first calculate the slope of the line connecting the endpoints of the interval: \((f(b)-f(a))/(b-a)=[(16)^(3/4)-(0)^(3/4)]/(16-0)\)=\(2sqrt(2).\) Then, we set f'(c)=2sqrt(2) and solve for c:

\(f'(c)=(3/4)c^(-1/4)=2sqrt(2)c^(-1/4)=(8/3)sqrt(2)c=(3/2)^(4/3)≈7.69\)

Therefore, the value of c that satisfies the conclusion of the mean value theorem is c≈7.69.

Step-by-step explanation:

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

To write the equation of the line with an x-intercept at -6 and a y-intercept at 2, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the y-intercept is given as 2, so the equation becomes y = mx + 2. To find the slope, we can use the formula (y2 - y1) / (x2 - x1) with the given points (-6, 0) and (0, 2). We find that the slope is 1/3. Thus, the equation of the line is y = (1/3)x + 2.

For the polynomial f(x) = -3x² + 6x, the degree is 2 and the leading coefficient is -3. The end behavior of the graph is determined by the degree and leading coefficient. Since the leading coefficient is negative, the graph will be "downward" or "concave down" as x approaches positive or negative infinity.

To find the zeros, we set the polynomial equal to zero and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two solutions: x = 0 and x = 2.

The x-intercept is the point where the graph intersects the x-axis, and since it occurs when y = 0, we substitute y = 0 into the polynomial and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two x-intercepts: (0, 0) and (2, 0).

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

John needs to make an annual beginning-of-the-year payment of approximately $369,238.68 to fund the estimated college costs of $196,000 in 10 years, given the after-tax rate of return of 8.65% compounded annually.

To compute the annual beginning-of-the-year payment necessary to fund the estimated college costs, we can use the present value of an annuity formula.

The present value of an annuity formula is given by:

P = A * [(1 - (1 + r)^(-n)) / r],

where P is the present value, A is the annual payment, r is the interest rate per period, and n is the number of periods.

In this case, John wants to accumulate $196,000 in 10 years, and the interest rate he can earn is 8.65% compounded annually. Therefore, we can substitute the given values into the formula and solve for A:

196,000 = A * [(1 - (1 + 0.0865)^(-10)) / 0.0865].

Simplifying the expression inside the brackets:

196,000 = A * (1 - 0.469091).

196,000 = A * 0.530909.

Dividing both sides by 0.530909:

A = 196,000 / 0.530909.

A ≈ 369,238.68.

The statement (3) The probability of occurrence in a given unit of time has a fixed number of trials is not true about the Poisson distribution.

In the Poisson distribution, the number of trials is not fixed, and each event in the Poisson distribution is considered a trial. The Poisson distribution is a type of discrete probability distribution that is used to calculate the probability of a certain number of events occurring in a specified interval of time or space. It is often used to model situations where the number of occurrences is rare but the average occurrence rate is known. The Poisson distribution is described by a single parameter, λ (lambda), which is equal to the expected number of occurrences in the specified interval. The Poisson distribution can also be used to calculate the probability of a certain number of events occurring over a given area, volume, or any other unit of measurement. This makes it a versatile tool in many different fields, including physics, biology, and finance. It is worth noting that the Poisson distribution assumes that the events are independent of each other, meaning that the occurrence of one event does not affect the probability of the occurrence of another event.

In conclusion, the statement (3) The probability of occurrence in a given unit of time has a fixed number of trials is not true about the Poisson distribution. The number of trials is not fixed, and each event in the Poisson distribution is considered a trial.

The exponential growth formula for bacteria growth is P(t) = 8600 \((2)^(t/5)\).

What is exponential growth?

     Exponential growth is a pattern of data that exhibits a greater increase over time, resulting in an exponential curve. Exponential is also a mathematical term meaning "with exponents". For example, if you raise a number to the 10th power, the number increases exponentially. Exponential growth is growth that increases at a constant rate.

Here given take Initial number of bacteria = 8600. rate of growth = 2.

It doubles every year. Then doubling time = 5 hours.

Now population growth after t years,

P(t) = Po \((2)^(t/5)\)

=> P(t) = 8600 \((2)^(t/5)\)

Let's use the variables x and y to represent the cost of a hot dog meal and a hamburger meal, respectively.

Then, we can write the following system of equations to describe the situation:

2x + 3y = 33 (Mrs. Dotson's purchases)

1x + 3y = 27 (Mr. Kent's purchases)

To solve this system of equations using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

2x + 3y = 33

-2x - 6y = -54

0x - 3y = -21

Simplifying the equation, we get:

y = 7

Substituting this value of y into either equation, we can solve for x:

2x + 3(7) = 33

2x + 21 = 33

2x = 12

x = 6

Therefore, hot dog meals cost $6 each, and hamburger meals cost $7 each.

The p-value for the given test is approximately 0.067, rounded to two significant digits. This was calculated by finding the area to the right of z=1.5 under the standard normal distribution.

It is given that Null hypothesis: H0: μ ≤ 0, Alternative hypothesis: H1: μ > 0, Population standard deviation: σ = 1, Test statistic: z = 1.5

To find the p-value, we need to calculate the probability of observing a z-value of 1.5 or greater under the null hypothesis. Since the population follows the standard normal distribution, we can use a standard normal table or a calculator to find this probability.

Using calculator, we can find that the area to the right of z = 1.5 is approximately 0.0668 (rounded to four decimal places).

Since this is a one-tailed test with the alternative hypothesis in the right tail, the p-value is equal to the area in the right tail beyond the observed z-value. Therefore, the p-value for the test is approximately 0.067 (rounded to two significant digits).
