Step-by-step explanation:
A number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times.
How does this frequency compare to the expected frequency based on the probability of
the number cube landing on an even number?
The frequency is 15 more than expected.
The frequency is 13 more than expected.
The frequency is 9 more than expected.
The frequency is 3 more than expected.
Done →
Given statement solution is :- The correct answer is: The frequency is 3 more than expected.
To determine the expected frequency of landing on an even number when rolling a fair six-sided number cube, we need to calculate the probability of landing on an even number and multiply it by the total number of rolls.
The number cube has six possible outcomes: 1, 2, 3, 4, 5, and 6. Of these, three are even numbers: 2, 4, and 6. Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.
The expected frequency can be found by multiplying the probability by the total number of rolls:
Expected frequency = Probability of landing on an even number × Total number of rolls
Expected frequency = 0.5 × 30 = 15
Now, we can compare the expected frequency (15) to the actual frequency (18) given in the problem statement.
The actual frequency is 18, and it is 3 more than the expected frequency (18 - 15 = 3).
Therefore, the correct answer is: The frequency is 3 more than expected.

Answer:
C
Step-by-step explanation:
We want to integrate:
\(\displaystyle \int\frac{4x^4+3}{4x^5+15x+2}\,dx\)
Notice that the expression in the denominator is quite similar to the expression in the numerator. So, we can try performing u-substitution. Let u be the function in the denominator. So:
\(u=4x^5+15x+2\)
By differentiating both sides with respect to x:
\(\displaystyle \frac{du}{dx}=20x^4+15\)
We can "multiply" both sides by dx:
\(du=20x^4+15\,dx\)
And divide both sides by 5:
\(\displaystyle \frac{1}{5}\, du=4x^4+3\,dx\)
Rewriting our original integral yields:
\(\displaystyle \int \frac{1}{4x^5+15x+2}(4x^4+3\, dx)\)
Substitute:
\(\displaystyle =\int \frac{1}{u}\Big(\frac{1}{5} \, du\Big)\)
Simplify:
\(\displaystyle =\frac{1}{5}\int \frac{1}{u}\, du\)
This is a common integral:
\(\displaystyle =\frac{1}{5}\ln|u|\)
Back-substitute. Of course, we need the constant of integration:
\(\displaystyle =\frac{1}{5}\ln|4x^5+15x+2|+C\)
Our answer is C.
100 Points! Algebra question. Use the given features to sketch a linear graph. Photo attached. Thank you!
The graph provided will be a linear graph with the function being y= 2x +4.
Since the x-intercept is -2 and the y-intercept is 4, we can plot the points (-2, 0) and (0, 4) on the graph.
The function is increasing for all values of x, which means the graph will have a positive slope. Let's assume a slope of 2, for example.
Using the slope-intercept form of a linear equation (y = mx + b), we can write the equation of the line:
y = 2x + 4
Now when the value of x is 1 the value of y will be :
y= 2*1+4
y= 6
For x = 2, y is:
y=8
For x= 3 y is:
y=10.
Thus we can see that the function will provide us with a linear graph with the points being (1,6), (2,8), (3,10).

(2 + g) (8)
= (2 + g) (8)
Add a 8 after the 2, and flip.
= (2)(8) + (g)(8)
= 16 + 8g
= 8g + 16
= (4) (8 + -5g)
Add another 4, then flip.
= (4) (8) + (4) (-5g)
= 32 − 20g
= - 20g + 32
−7 (5-n)
= (−7) (5 + -n)
Add another 7, then flip.
= (−7) (5) + (-7) (-n)

Use the distributive property.
a (b + c) = ab + ac
a = 8
b = 2m

Step-by-step explanation:
Hi there!
We are given the points (1,1) and (-2, -11) and we want to write the equation of the line in slop-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
So let's find the slope of the line
The formula for the slope calculated from two points is \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points
We have everything we need to calculate the slope, let's just label the points to avoid confusion
\(x_1=1\\y_1=1\\x_2=-2\\y_2=-11\)
Now substitute those values into the formula
m=\(\frac{y_2-y_1}{x_2-x_1}\)
m=\(\frac{-11-1}{-2-1}\)
Subtract
m=\(\frac{-12}{-3}\)
Divide
m=4
So the slope of the line is 4
Here is the equation of the line so far:
y=4x+b
We need to find b
As the equation passes through both (1,1) and (-2, -11), we can plug either one of them into the equation to solve for b
Taking (1,1) will give us this:
1=4(1)+b
Multiply
1=4+b
Subtract 4 from both sides
-3=b
Substitute -3 as b into the equation
y=4x-3

which of the following represents the graph of f(x) = 2^x
The graph of f(x) =\(2^{x}\) is an increasing function, meaning that as x increases, the value of f(x) also increases.
What is graph?Graph is a data structure that consists of nodes (vertices) and edges. A graph is used to represent relationships between objects, such as a network of roads or a social network. Graphs can be directed (with arrows going in one direction) or undirected (with no direction). Graphs can be weighted (with values assigned to edges) or unweighted (without values). Graphs are used in many areas, including computer science, mathematics, machine learning, and engineering.
The graph of f(x) =\(2^{x}\) is a exponential graph that has a vertical asymptote of y = 0 and a horizontal asymptote of x = infinity. Its graph is shown in the figure below:
(Graph of f(x) = \(2^{x}\))
The graph of f(x) = \(2^{x}\) is an increasing function, meaning that as x increases, the value of f(x) also increases. As x approaches negative infinity, the value of f(x) approaches 0. As x approaches positive infinity, the value of f(x) approaches infinity.
The domain of f(x) = \(2^{x}\) is the set of all real numbers, and the range of this function is the set of all positive real numbers. The graph of this function has no local minima or maxima, and it is continuous everywhere.
This graph is useful in many areas of mathematics, such as calculus, probability, and statistics. It is also used in physics and engineering to model exponential growth and decay.

what steps are needed to find the equation of a line given the graph?
The equation of the line is y = x.
To find the equation of a line given its graph, you need to follow the steps below.
Step 1: Determine the slope of the line.The slope of the line can be determined using the formula: slope = rise/run or m = Δy/Δx. Rise is the change in the y-coordinates and run is the change in the x-coordinates.
Step 2: Determine the y-intercept of the line.The y-intercept is the point where the line intersects the y-axis. You can determine the y-intercept by looking at the point where the line crosses the y-axis on the graph. The y-intercept is denoted by the letter b.
Step 3: Write the equation of the lineThe equation of the line can be written in slope-intercept form, which is y = mx + b. The slope (m) and y-intercept (b) that were determined in steps 1 and 2 are used to substitute into this equation. Thus, the equation of the line becomes y = slope(x) + y-intercept.
Example:Let's say you are given the graph of a line below: .
Step 1: Determine the slope of the line.To determine the slope of the line, you need to choose two points on the line and calculate the rise and run. Let's choose the points (2, 1) and (4, 3). The rise is 2 (3 - 1) and the run is 2 (4 - 2). Therefore, the slope of the line is: m = 2/2 = 1.
Step 2: Determine the y-intercept of the lineThe line crosses the y-axis at the point (0, 0). Therefore, the y-intercept of the line is b = 0.
Step 3: Write the equation of the line.The equation of the line in slope-intercept form is y = mx + b. Substituting the slope and y-intercept into this equation gives: y = 1x + 0 or y = x.

Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1150 and 1308 grams? (b) What is the probability that a randomly selected broiler weighs more than 1510 grams? (c) Is it unusual for a broiler to weigh more than 1610 grams? Round the answers to at least four decimal places.
Answer:
a) 0.2318
b) 0.2609
c) No it is not unusual for a broiler to weigh more than 1610 grams
Step-by-step explanation:
We solve using z score formula
z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean 1387 grams and standard deviation 192 grams. Use the TI-84 Plus calculator to answer the following.
(a) What proportion of broilers weigh between 1150 and 1308 grams?
For 1150 grams
z = 1150 - 1387/192
= -1.23438
Probability value from Z-Table:
P(x = 1150) = 0.10853
For 1308 grams
z = 1308 - 1387/192
= -0.41146
Probability value from Z-Table:
P(x = 1308) = 0.34037
Proportion of broilers weigh between 1150 and 1308 grams is:
P(x = 1308) - P(x = 1150)
0.34037 - 0.10853
= 0.23184
≈ 0.2318
(b) What is the probability that a randomly selected broiler weighs more than 1510 grams?
1510 - 1387/192
= 0.64063
Probabilty value from Z-Table:
P(x<1510) = 0.73912
P(x>1510) = 1 - P(x<1510) = 0.26088
≈ 0.2609
(c) Is it unusual for a broiler to weigh more than 1610 grams?
1610- 1387/192
= 1.16146
Probability value from Z-Table:
P(x<1610) = 0.87727
P(x>1610) = 1 - P(x<1610) = 0.12273
