Answer:

Answer is 1/3

Step-by-step explanation:

If you divide the numerator and denominator by five you get 3/9

3/9 can be reduced if you divide the numerator and denominator by 3, then your answer is 1/3 (since 3 goes into 3 once, and 3 goes into 9 three times.)

Answer:

The number is 42.

Significant independent variables makes a good regression model.

A reasonable high R-squared score makes sense if your regression model includes independent variables that are statistically significant. According to the statistical significance, shifts in the dependent variable are correlated with changes in the independent variables.

Accordingly, a high R-squared value shows that your model adequately accounts for the variation in the dependent variable.

Using Euler integration, the next values of x and y can be determined as follows:

x_next = x_current + delta_X

y_next = y_current + delta_X * y'

Euler integration is a numerical method used to approximate solutions to differential equations. It is based on the concept of dividing the interval into small steps and using the derivative at each step to calculate the next value. In this case, we are given the current values of x=2, y=8, and y'=9, with a step size of delta_X=5.

To determine the next values of x and y, we use the following formulas:

x_next = x_current + delta_X

y_next = y_current + delta_X * y'

Substituting the given values into the formulas, we have:

x_next = 2 + 5 = 7

y_next = 8 + 5 * 9 = 53

Therefore, the updated values of x and y using Euler integration are x=7 and y=53.

It's important to note that Euler integration provides an approximate solution and the accuracy depends on the chosen step size. Smaller step sizes generally lead to more accurate results. Other numerical methods, such as Runge-Kutta methods, may provide more accurate approximations.

The statisticians evaluate all of the above options: A. The population being measured, B. The method used for the survey, and C. The outcome of the survey.

To measure the quality of a survey, statisticians consider various factors related to the survey process and its outcomes. Evaluating only one aspect may not provide a comprehensive understanding of the survey's quality.

A. The population being measured: The quality of a survey depends on how well the target population is defined and represented.

Statisticians assess whether the chosen population accurately reflects the intended group and if any biases or sampling errors are present.

B. The method used for the survey: The survey methodology plays a crucial role in obtaining reliable and valid data.

Statisticians assess the survey design, sampling techniques, data collection methods, questionnaire quality, and other factors to determine if the chosen method is appropriate and likely to yield accurate results.

C. The outcome of the survey: The survey's outcomes are analyzed to evaluate the quality of the data collected. This includes examining response rates, data completeness, measurement validity, reliability, and other statistical measures.

Statisticians assess the overall quality and integrity of the survey's outcomes to determine if they align with the research objectives and provide meaningful insights.

Step-by-step explanation:

When given a function f defined as f(x) = ax + b, where a and b are constants, and f(3) = 10 and f(8) = 12, the values of a and b are 0.4 and 0.8, solved using a system of equations. So the right answer is O a = 0.4, b = 8.8.

The values of a and b can be determined as follows:

f(3) = 10 implies that 10 = 3a + bf(8) = 12 implies that 12 = 8a + b

We can solve this system of equations to get the values of a and b.

One way to do this is to use elimination: We can eliminate b by subtracting the first equation from the second equation: 12 - 10 = (8a + b) - (3a + b)2 = 5a

Solving for a, we get a = 2/5.

Substituting this value of a into the first equation, we can solve for b:10 = 3a + bb = 10 - 3a

Substituting the value of a = 2/5, we get: b = 10 - 3(2/5)b = 10 - 6/5b = 44/5

Therefore, the values of a and b are: a = 2/5 and b = 44/5.

The correct answer is: a = 0.4, b = 8.8.

Answer:

width = 1.77845 ft

length = 7.1138 ft

height = 5.691 ft

total cost = $759.09

Step-by-step explanation:

volume = length x width x height

length = 4 width

base of the rectangle = 4 x 1 w = 4w²

72 (volume) = 4w²h

18 = w²h

f(c) = (2 x 4w² x $10) + (2 x wh x $5) + (2 x 4wh x $5)

f(c) = 80w² + 10wh + 40wh

f(c) = 80w² + 50wh

since we need only 1 variable (width), we have to substitute h:

h = 18/w²

f(c) = 80w² + 50w(18/w²) = 80w² + 900/w

f'(c) = 160w + 900/w²

0 = (160w³ + 900)/w²

0 = 160w³ + 900

0 = 20(8w³ + 45)

0 = 8w³ + 45

8w³ = -45

w³ = -45/8

w = ∛-45/8 = -1.77845 and 1.77845

since w cannot be negative, then it must be 1.77845

Answer:

Step-by-step explanation:

Subtract 4 from both sides

y - 4 = 3(x+2)^2

Divide 3 from both sides

(y-4)/3 = (x+2)^2

Square root both sides

SQRT((y-4)/3) = x + 2

Subtract 2 from both sides

x = SQRT((y-4)/3) - 2

To find the number of integers less than 305 that are divisible by 3, we can divide 305 by 3 and round down to the nearest integer. This gives us 101. However, we need to subtract 1 to exclude the number 305 itself, so there are 100 numbers less than 305 that are divisible by 3.

A number is said to be divisible if it divides evenly (leaving no residue). 34, for instance, is divisible by 2 since 2 enters 34 equally. 34 is not divisible by 3 since it would result in a remainder.

According to the three-digit rule of division, a whole number is said to be divisible by three if the total of all its digits is precisely divided by three. A number's ability to be divided by three can be determined without executing division.

Answer:

k=6

Step-by-step explanation:

For a piecewise function to be continuous, the left-side and right-side limits must be equal to each other. Therefore, the left-side limit of f(x) is 8 because the derivative of 2x^2 is 4x, and then directly substituting x=2 gives us 4(2)=8. Therefore, the right-side limit must also equal 8. Therefore, k must be 6 because 2+6=8.

Answer:

Step-by-step explanation:

Since ∆ ABC is a triangle the sum of it's angles add up to 180°

In order to find x we must first find \(\angle\) AED

Let \(\angle\) AED = E

To find \(\angle\) AED add up all the angles in the triangle and equate it to 180°

That's

35 + 90 + E = 180

125 + E = 180

E = 180 - 125

E = 55°

E and x lie on a straight line

So we have

x + 55 = 180°

x = 180 - 55

It is false as the left and right ends of the normal probability distribution extend indefinitely, approaching but never touching the horizontal axis.

The statement is false because the left and right ends of the normal probability distribution do not extend indefinitely. In reality, the normal distribution is defined over the entire real number line, meaning it extends infinitely in both the positive and negative directions. However, as the values move further away from the mean (the center of the distribution), the probability density decreases. This means that although the distribution approaches but never touches the horizontal axis at its tails, the probability of observing values extremely far away from the mean becomes extremely low. Thus, while the distribution theoretically extends infinitely, the practical probability of observing values far from the mean decreases rapidly.

The coordinate matrix of x relative to the orthonormal basis b is then: [x]b = [19, -9, 10]

To get the coordinate matrix of x relative to the orthonormal basis b in Rn, we need to express x as a linear combination of the basis vectors in b. We can do this by using the formula: x = [x · b1]b1 + [x · b2]b2 + [x · b3]b3
where · denotes the dot product and b1, b2, and b3 are the orthonormal basis vectors in b.
First, we need to normalize the basis vectors:
|b1| = √(3^2 + 4^2) = 5
b1 = (3/5, 4/5, 0)
|b2| = √(4^2 + 3^2) = 5
b2 = (-4/5, 3/5, 0)
|b3| = 1
b3 = (0, 0, 1)
Next, we compute the dot products:
x · b1 = (5, 20, 10) · (3/5, 4/5, 0) = 19
x · b2 = (5, 20, 10) · (-4/5, 3/5, 0) = -9
x · b3 = (5, 20, 10) · (0, 0, 1) = 10
Using these values, we can express x as a linear combination of the basis vectors:
x = 19b1 - 9b2 + 10b3
The coordinate matrix of x relative to the orthonormal basis b is then:
[x]b = [19, -9, 10]
Note that this matrix is a column vector since x is a column vector.

Solution:

To draw a perpendicular bisector of a line segment, first we need to open the compass more than half of the distance between the end points of the segment.

End points of the segment CD are C and D.

So, to draw a perpendicular bisector of CD, the compass should be stretched out  more than halfway from point C to the other endpoint D.

Therefore, the correct option is C.
