Answer:

the function is decreasing.

the slope is -3/4 and the y-intercept is 7.

the function is linear and continuous.

y = -3/4 x + 7 3 this function.

Step-by-step explanation:

"the function is linear and discrete" is false. there are no interruptions or steps in the curve. it is a continuous curve.

the usual function form of a line is

y = ax + b

"a" being the slope, "b" being the y-intercept.

that is why the other statements are false.

A sample of 81 items is taken from a population with a standard deviation of 45 kilograms. The sample mean is 112 kilograms. What weights are included in the 99.7% of confidence interval?

Answers

The confidence interval of the given data is (117, 107).

Given that:

Sample mean X = 112

Standard deviation σ = 45

Sample size n = 81

Confidence level = 99.7%

Z Score = (x − μ )/σ

Z score = 0.9944

Confidence interval = X±z (σ/√n)

= 112±0.9944(45/√81)

= 112±0.9944(5)

the volume of both of these trapezoid prisms is 24 cubic units. their heights are 6 and 8 units as labeled. What is the area of a trapezoidal base of each prism

Answers

the area of the trapezoidal base of the first prism is 9 square units, and the area of the trapezoidal base of the second prism is 16 square units.

What is Volume of both the trapezoidal prisms?

volume = area of cross section of object*  height of object (A)

V = (1/2) * h * (b1 + b2) * H

For the first trapezoid prism, we have:

24 = (1/2) * 6 * (b1 + b2) * 8

Simplifying this equation, we get:

3 = (b1 + b2)

For the second trapezoid prism, we have:

24 = (1/2) * 8 * (b1' + b2') * 6

Simplifying this equation, we get:

4 = (b1' + b2')

A = (1/2) * h * (b1 + b2)

For the first trapezoidal prism:

A = (1/2) * 6 * 3

A = 9 square units

For the second trapezoidal prism:

A = (1/2) * 8 * 4

A = 16 square units

Therefore, the area of the trapezoidal base of the first prism is 9 square units, and the area of the trapezoidal base of the second prism is 16 square units.

A cylinder is sliced at an angle, leaving the shape shown at right. The shorter height

What is the volume of this sliced cylinder?

Answers

1) The opposite face of the black circle is, Plus +.

2) The volume of the sliced cylinder is 96π cubic cm.

We have to given that;

Three different views of identical cubes are shown at right.

Now, From first and third dice,

Star is just opposite to symbol ~.

Hence, From second and third dice,

The opposite face of the black circle is, +

2) For the volume of the sliced cylinder, we need to first find the volume of the full cylinder and then subtract the volume of the smaller cylinder that's left after the slice is made.

Hence, The volume of the full cylinder is given by:

V = πr²h

Where r is the radius of the base and h is the height of the full cylinder.

Using the given values, we can find:

V = π(4²)(18)

V = 288π cubic cm

Now, let's find the volume of the smaller cylinder. The shorter height of 12 cm tells us that the slice removed 6 cm from the top of the cylinder. So the height of the smaller cylinder is,

18 - 6 = 12 cm.

The radius remains the same at 4 cm.

Thus, the volume of the smaller cylinder is:

V = π(4²)(12)

V = 192π cubic cm

Finally, we can find the volume of the sliced cylinder by subtracting the volume of the smaller cylinder from the volume of the full cylinder;

⇒ V = (288π) - (192π)

⇒ V = 96π cubic cm

Therefore, the volume of the sliced cylinder is 96π cubic cm.

A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this
tumor occurred in a certain town, which had 17,199 children.
a. Assuming that this tumor occurs as usual, find the mean number of cases in groups of
17,199 children.
b. Using the unrounded mean from part (a), find the probability that the number of tumor cases in a group of
17.199 children is 0 or 1.
c. What is the probability of more than one case?
d. Does the cluster of four cases appear to be attributable to random chance? Why or why not?

Answers

a) The mean number of cases in groups of 17,199 children is 0.187.

b) The probability of 0 or 1 case in a group of 17,199 children is 0.832.

c)  The probability of more than one case in a group of 17,199 children is 0.168.

d) The expected number of cases is 3.214 and the actual number of cases is 4

What is the probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.

For example, if you flip a fair coin, the probability of it landing heads up is 0.5, because there are two equally likely outcomes (heads and tails), and one of them is heads. Similarly, if you roll a fair six-sided die, the probability of rolling a 3 is 1/6, because there are six equally likely outcomes (rolling a 1, 2, 3, 4, 5, or 6), and only one of them is a 3.

According to the given information

a. Assuming that the tumor occurs as usual, the mean number of cases in groups of 17,199 children can be calculated as:

mean = (probability of a single case) x (number of children) = 0.000011 x 17,199 = 0.187

So the mean number of cases in groups of 17,199 children is 0.187.

b. The probability of 0 or 1 case can be found using the Poisson distribution, which models the probability of a certain number of events occurring in a fixed interval of time or space, given the mean rate of occurrence. In this case, the Poisson distribution can be used to find the probability of 0 or 1 case in a group of 17,199 children, given the mean of 0.187.

The probability of 0 or 1 case can be calculated as follows:

P(0 or 1 case) = P(0 case) + P(1 case)

= (e⁽⁻⁰°¹⁸⁷⁾ * 0.187⁰) / 0! + (e⁽⁻⁰°¹⁸⁷⁾ * 0.187¹) / 1!

= 0.832

Therefore, the probability of 0 or 1 case in a group of 17,199 children is 0.832.

c. The probability of more than one case can be found as:

P(more than one case) = 1 - P(0 or 1 case)

= 1 - 0.832

= 0.168

Therefore, the probability of more than one case in a group of 17,199 children is 0.168.

d. To determine whether the cluster of four cases is attributable to random chance, we can compare the actual number of cases with the expected number of cases based on the mean rate of occurrence.

The expected number of cases in a group of 17,199 children can be found by multiplying the mean rate of occurrence (0.187) by the number of groups:

expected number of cases = 0.187 x 17199 = 3.214

Since the expected number of cases is 3.214 and the actual number of cases is 4.

The equation of the function g(x) is g(x) = f(x+3) + 4 and g(x) = log₂(x+3) + 4

State g(x) in terms of f(x)

To shift the function 3 units left, we replace x with x+3. To shift it 4 units up, we add 4 to the function.

Therefore, the expression for g(x) in terms of f(x) is:

g(x) = f(x+3) + 4

Determine equation of the function g(x)

Substituting f(x) = log₂(x), we get:

g(x) = log₂(x+3) + 4

The equation of the function g(x) is g(x) = log₂(x+3) + 4.

State the domain, range, asymptotes of g(x)

The domain of g(x) is all x such that x+3 > 0, since the argument of the logarithm must be positive.  This gives x > -3.

The range of g(x) is all real numbers, since the logarithm takes on all real values.

The vertical asymptote is x = -3, since this is where the function becomes undefined (the argument of the logarithm becomes 0).

The horizontal asymptote is y = 4, since as x approaches infinity or negative infinity, the function approaches 4.

April shoots an arrow upward at the speed of 80 feet per second from a platform 50 feet high. The pathway of the arrow can be represented by using the equation h(t)=-16t^2+V₀t+h₀
a) What is the maximum height of the arrow?
b) About how many seconds will it take for the arrow it reach the ground?
c) How many seconds after launch will the arrow be 114 feet high?
I need this quickly please

Answers

a) To find the maximum height of the arrow, we need to find the vertex of the parabolic function. The vertex is located at t = -b/2a, where a = -16, b = V_0 = 80, and h_0 = 50. Therefore, t = -80 / (2 * (-16)) = 2.5 seconds. Plugging t = 2.5 into the equation gives:

h(2.5) = -16(2.5)^2 + 80(2.5) + 50 = 125 feet.

Therefore, the maximum height of the arrow is 125 feet.

b) To find how long it takes for the arrow to reach the ground, we need to find the value of t when h(t) = 0. Substituting h(t) = 0 and solving for t, we get:

0 = -16t^2 + 80t + 50
t^2 - 5t - 50/16 = 0
(t - 10/4)(t + 5/4) = 0

Therefore, t = 2.5 seconds or t = -1.25 seconds. Since the time cannot be negative, the arrow will hit the ground after approximately 2.5 seconds.

c) To find the time when the arrow is 114 feet high, we need to solve the equation h(t) = 114. Substituting h(t) = 114 and simplifying, we get:

-16t^2 + 80t + 50 = 114
-16t^2 + 80t - 64 = 0
t^2 - 5t + 4 = 0
(t - 4)(t - 1) = 0

Therefore, t = 1 second or t = 4 seconds. Since the arrow is at a height of 114 feet after it has been launched, the answer is t = 1 second.

The volume of a rectangular prism is calculated using the formula V=Zoey, where V is the volume of the prism, I and W are the length and width base of the prism, respectively and h is the height of the prism

Answers

Answer:

I'm sorry, but there seems to be an error in the formula you provided. The correct formula for finding the volume (V) of a rectangular prism is V = l x w x h, where l, w, and h are the length, width, and height of the prism, respectively.

Prehistoric cave paintings were discovered in a cave in France. The paint contained
17% of the original carbon-14. Use the exponential decay model for carbon-14,
A=Age-0.000121t
to estimate the age of the paintings?

Answers

First, we need to find the decay constant, k. Since the half-life of carbon-14 is 5,700 years, we can use the formula:

k = ln(1/2) / 5700

k = -0.000121

Now we can use the formula for exponential decay to find the age of the paintings:

0.17 = e^(-0.000121t)

ln(0.17) = -0.000121t

t = ln(0.17) / (-0.000121)

t ≈ 22,000 years

Therefore, the age of the paintings is approximately 22,000 years.

The roots of the equation $2x^2-mx+n=0$ sum to $6$ and multiply to $10$. What is the value of $m+n$?

The value of m + n for the given quadratic equation is 8.

What is a quadratic equation?

A quadratic equation is a polynomial equation of the form:

[tex]ax^{2} +bx+c=0[/tex]

where x is the unknown variable, and a,b and c are constants. The highest power of the variable x in a quadratic equation is 2, hence the term "quadratic". The constants a,b and c are known as the coefficients of the quadratic equation.

According to the given information:

Let's denote the roots of the quadratic equation [tex]2x^{2} -mx+n=0[/tex] as r1 and r2, with r1 and r2 being the roots of the equation.

Given that the sum of the roots is 6 and the product of the roots is 10. This gives us the following equations:

r1 + r2 = 6 ------ (1)

r1*r2 = 10 ------- (2)

We can use these equations to solve for the values of m and n.

The sum of the roots r1 + r2 is also equal to [tex]\frac{-m}{2}[/tex] by Vieta's formulas, which state that the sum of the roots of a quadratic equation [tex]ax^{2} +bx+c=0[/tex] is given by [tex]\frac{-b}{a}[/tex]. Therefore, we can write:

[tex]\frac{-m}{2}[/tex] = 6

Solving for m, we get:

m = -2*6 = -12  ----------(3)

The product of the roots r1*r2 is also equal to n/2 by Vieta's formulas, which states that the product of the roots of a quadratic equation [tex]ax^{2} +bx+c=0\\[/tex] is given by [tex]\frac{c}{a}[/tex]. Therefore, we can write:

n/2 = 10

Solving for n, we get:

n = 2 * 10 = 20  ------------(4)

Now, we can find the value of m+n by substituting the values of m and n from equations (3) and (4) respectively:

m + n = -12 + 20 = 8

So, the value of m+n is 8.
