Step-by-step explanation:

To determine the placement of 4.7 on a number line between two decimals, 4/7 should be placed between the pair of decimals 0.57 and 0.58 on a number line.

The number 4.7 falls between the integers 4 and 5, so we need to find the decimal values that come after 4 and before 5.  The decimal value that comes after 4 is 4.1, and the decimal value that comes before 5 is 4.9.
1. Convert the fraction 4/7 to a decimal.
2. Identify the two consecutive decimals on the number line that the converted decimal falls between.

Step 1: Convert 4/7 to a decimal.
To do this, divide the numerator (4) by the denominator (7):
4 ÷ 7 ≈ 0.5714 (rounded to 4 decimal places)

Step 2: Identify the two consecutive decimals.
Now, we know that 0.5714 is the decimal equivalent of 4/7. To determine the pair of decimals on the number line, we can see that 0.5714 falls between 0.57 and 0.58.

So, 4/7 should be placed between the pair of decimals 0.57 and 0.58 on a number line.

Answer:

w = 3.2 cm

Step-by-step explanation:

Perimeter of a rectangle = 2(l + w)

Given values:

Substitute the given values into the formula and solve:

39.2 = 2(16.4 + w)

39.2 = 2(16.4 + w)

39.2 = 32.8 + 2w

6.4 = 2w

6.4 / 2 = 2w / 2

3.2 = w

Check your work:

39.2 = 2(16.4 + 3.2)

39.2 = 2(19.6)

39.2 = 39.2 ✅

Final answer: w = 3.2 cm

Answer:

4 pack

Step-by-step explanation:

£2.04 ÷ 4 is 51p. If we divide £2.04 by 4 (we are dividing it by 4 because that is the amount of rolls) it gives us how much 1 roll is in that pack. 1 roll = 51p in the 4 pack.

£4.68 ÷ 9 is 52p. If we divide £4.68 by 9 (we are dividing it by 9 because that is the amount of rolls) it gives how much 1 roll is in that pack. 1 roll = 52p.

Therefore, the 4 pack is cheaper as 1 roll costs less. The 4 pack is better value.

A majority of the college seniors in the survey are not planning to attend graduate school. The discipline of business constitutes the majority of individuals in the survey.

In more detail, let's analyze the crosstabulation table. To determine if a majority of the seniors are planning to attend graduate school, we can compare the total number of "yes" responses (140) to the total number of respondents (400).

Since 140 is less than 50% of 400, we can conclude that a majority of the seniors are not planning to attend graduate school.

To identify which discipline constitutes the majority of individuals in the survey, we can examine the column totals.

The highest column total corresponds to the "engineering" discipline, with 146 individuals. Therefore, engineering is the discipline that constitutes the majority of individuals in the survey.

To compute the row percentages, we divide each cell by its respective row total and multiply by 100. This gives us the percentage of students in each undergraduate major who plan to attend graduate school.

By analyzing these percentages, we can identify any patterns or relationships between the students' majors and their intention of attending graduate school.

To compute the column percentages, we divide each cell by its respective column total and multiply by 100. This allows us to examine the percentage of students who plan to attend graduate school within each undergraduate major category.

For the first question, we are given two functions, f(x) and g(x), and we are asked to find f(g(0)). First, we need to find the value of g(0):

g(x) = -6x² - 2x + 6
g(0) = -6(0)² - 2(0) + 6
g(0) = 6

Now, we need to find f(g(0)):

f(x) = x - 2
f(6) = 6 - 2
f(6) = 4

So, the answer to the first question is 4.

For the second question, we are given the function h(x) and asked to decompose it into component functions f(x) and g(x) so that h(x) = f(g(x)). The function h(x) is:

h(x) = (3x - 5)²

Comparing this with the given options, the correct decomposition is:

h(x) = f(g(x)), where f(x) = x² and g(x) = 3x - 5

This is because when we apply f(g(x)), we get:

f(g(x)) = f(3x - 5) = (3x - 5)²= h(x)

Therefore, the directional derivative of f at P=(1,-1,-2) in the direction of A=3i+2j-6k is -2.

To find the directional derivative of f(x,y,z) at P=(1,-1,-2) in the direction of A=3i+2j-6k, we first need to find the gradient of f at P, which is given by:

grad(f) = ∇f = (∂f/∂x)i + (∂f/∂y)j + (∂f/∂z)k

Here, f(x,y,z) = xy + yz + zx, so we have:

∂f/∂x = y + z

∂f/∂y = x + z

∂f/∂z = x + y

Thus, at P=(1,-1,-2), we have:

∇f(P) = (∂f/∂x)i + (∂f/∂y)j + (∂f/∂z)k

= (y+z)i + (x+z)j + (x+y)k

= (0+(-2))i + (1+(-2))j + (1+0)k

= -2i - 1j + 1k

Next, we need to find the unit vector in the direction of A:

|A| = sqrt(3^2 + 2^2 + (-6)^2) = 7

u = A/|A| = (3/7)i + (2/7)j - (6/7)k

Finally, we can compute the directional derivative of f at P in the direction of A as:

(DAf) | 1(1,-1,-2) = ∇f(P) · u

= (-2i - 1j + 1k) · (3/7)i + (2/7)j - (6/7)k

Step-by-step explanation:

The numbers that cannot be probabilities are: square root of 2, -53, 5/3, and 1.31.

Probability is a measure of the likelihood of a particular event occurring in a random experiment. It is a value between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

In statistics, probability is used to make predictions or draw inferences about a population based on a sample of data. For example, if we were to flip a coin, the probability of getting heads is 0.5, or 50%. In general probability can be defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, which is the mathematical framework behind the random experiments.

From the set of numbers, 0, 0.08, and 3/5 are all possible values of probability.

Therefore, square root of 2, -53, 5/3, and 1.31 cannot be probabilities.

Answer:

y = (-1/2)x + 2

Step-by-step explanation:

The black line slopes down as we move from left to right, so we conclude that the slope is negative.   From (0,  2) to (4, 0), y drops by 2 units (the rise) and x increases by 4 units (run).

Thus the slope is m = rise / run = -2/4, or m = -1/2.

The y-intercept is (0, 2), so the value of b in the equation y = mx + b is 2.

Thus the equation of this line is y = mx + b  =>  y = (-1/2)x + 2

However, this answer does not make sense, as angles in a triangle cannot be negative. This means that there is no solution to this problem .

To solve this problem, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Let's first find the measure of angle P:

m∠P + m∠Q + m∠R = 180

Substituting in the given measures:

(x + 13) + (10x + 13) + (2x - 2) = 180

Simplifying and solving for x:

13x + 24 = 180

13x = 156

x = 12

So m∠P = (x + 13) = 25 degrees.

Next, we can use the fact that the angles opposite equal sides in a triangle are congruent. Since we know that PR and QR are equal, we have:

m∠P = m∠R

So m∠R = 25 degrees.

Finally, we can find m∠Q:

m∠Q = m∠P + m∠R - 180

Substituting in the values we found:

m∠Q = 25 + 25 - 180 = -130

However, this answer does not make sense, as angles in a triangle cannot be negative. This means that there is no solution to this problem.

The pH of the mixture is calculated using the formula pH = 14 - pOH. And, the required pH of the mixture is 10.45.

The pH value of the solutions helps to measure the hydrogen ion or H⁺ concentration in the solution. First, let's find the number of moles of OH⁻ ions present in the solution,

\(\begin{aligned}\mathrm{moles\;OH^-\;present} &= \mathrm{0.89\;ml \times \frac{1\; L}{1000\;ml} \times 0.0467\;mol/L}\\& = \mathrm{4.16\times10^{-5}\;mol}\end{aligned}\)

Then, the final volume of the solution is calculated as,

Final volume = Volume of water + Volume of NaOH

Final volume = 146.8 ml + 0.89 ml = 147.69 ml =  0.14769 L

The final concentration of OH⁻ ions is given by,

Final [OH-] = number of moles of OH⁻ /Final volume

Final [OH-] = 4.16×10⁻⁵ mol /0.14769 L = 2.82×10⁻⁴ M

Now, the pOH is calculated as follows,

pOH = -log 2.82×10⁻⁴

pOH = 3.55

And, the pH is calculated using pOH as,

pH = 14 - pOH

pH = 14 - 3.55

pH = 10.45

The required pH is 10.45.
