Answer:

Step-by-step explanation:

The geometric tolerance that can be measured with a dial indicator to determine the variation of surface points as the part is rotated about a datum axis is circular runout.

Circular runout is a type of circularity control that defines a tolerance zone in which an object's surface can rotate around a datum axis. When the object is turned about the axis, the height variation between the surface and the axis must remain within the tolerance zone defined by circular runout.

In the case of a circular feature, the circular runout tolerance specifies the amount of circular deviation from the circular form that is allowable. Circular runout is used to control part wobble or out-of-roundness while a shaft or disk rotates about an axis.

Step-by-step explanation:

To solve the problem, we start by labeling 1/2 of 7/8 like this:

N1/D1 of N2/D2

Then we use this fraction of a fraction formula to solve the problem:

(N1 x N2) / (D1 x D2)

When we enter 1/2 of 7/8 into the formula, we get:

(1 x 7) / (2 x 8) = 7/16

Therefore, the answer to 1/2 of 7/8 in its lowest form is:

1/2 of 7/8 = 7/16

Answer:

False.

Step-by-step explanation:

Because 12 and 9 are both multiples of 3.

The correct expressions are;

B). 2/2 + 2/2 + 1/2 = 2.5

D). 1 1/2 + 1/2 + 1/2 = 2.5

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Danny has 2 1/2 pounds of coffee grounds.

2 1/2 = 2.5

The choices are given in the image.

A). 3/2 + 2/2 + 1/2 = 6/2 = 3 ≠ 2.5.

B). 2/2 + 2/2 + 1/2 = 2.5

C).  1 + 1 + 1/2 + 1/2

But this shows the situation for four days,

So, this option is discarded.

D). 1 1/2 + 1/2 + 1/2 = 2.5

Therefore, B and D are the correct options.

The following can be answered by the concept of Trigonometry.

The rearranged functions for each case, using appropriate mathematical techniques and identities:

(a) For 1 - cos(x) / x², we can use the identity sin²(x) + cos²(x) = 1 and rearrange as follows:
1 - cos(x) = sin²(x) / (1 + cos(x))
Then, divide by x² to get the rearranged function:
(sin²(x) / (1 + cos(x))) / x²

(b) For log(x + 1) - log(x) with x being large, we can use the logarithmic property of subtraction to combine the logs:
log((x + 1) / x)
As x is large, the expression simplifies to:
log(1 + (1/x))

(c) For sin(a + x) - sin(a), we can use the angle sum identity for sine:
sin(a + x) - sin(a) = (sin(a)cos(x) + cos(a)sin(x)) - sin(a)
Rearrange to get:
cos(a)sin(x) + sin(a)(cos(x) - 1)

(d) For √(1 + x - 1), we can simplify by removing the 1 and -1 inside the square root:
√(x)

(e) For √(4 + x - 2) / x, we can first simplify inside the square root:
√(2 + x) / x

These rearranged functions help avoid loss-of-significance errors in each of the given cases.

There are 10,000 possible code combinations for a 4-digit code on a standard keypad with digits 0 through 9.

To calculate the number of possible code combinations for a 4-digit code on a standard keypad with digits 0 through 9, we need to use the fundamental counting principle.

The fundamental counting principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together. This principle can be extended to any number of tasks.

For a 4-digit code, each digit can be chosen independently from the other digits, and there are 10 possible digits to choose from (0-9). Therefore, using the fundamental counting principle, we can calculate the number of possible code combinations as follows:

Number of possible code combinations = number of choices for the first digit x number of choices for the second digit x number of choices for the third digit x number of choices for the fourth digit

Number of possible code combinations = 10 x 10 x 10 x 10 = 10,000

This means that the chances of guessing the correct code by random chance are 1 in 10,000.

C. When elements are represented in a Venn diagram (using circles), the placement of elements inside or outside the circles indicates their relationship to the sets being represented.

D. Yes, the elements written at the intersection of both circles form a subset of the two sets.

C. Place an element inside a circle to indicate that it is a member of the set indicated by the circle.

An element that is positioned at the intersection of two circles denotes an element that is a part of both sets that are symbolized by those circles.

Outside the circles: In a Venn diagram, an element that is positioned outside every circle does not belong to any of the sets being represented.

D. This is so because these components are a part of the intersection of the two sets and as such, they are a part of both sets. In set theory, all of the components that are shared by two sets are contained in their intersection. Due to their simultaneous membership in both sets, the elements at the intersection are a subset of both sets.

Answer:

f < 1

Step-by-step explanation:

8(3f−6)<−24

Divide both sides by 8. Since 8 is positive, the inequality direction remains the same.

3f−6< \(\frac{-24}{8}\)

Divide −24 by 8 to get −3.

3f−6<−3

Add 6 to both sides.

3f<−3+6

Add −3 and 6 to get 3.

3f<3

Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.

\(f<\frac{3}{3}\)

Divide 3 by 3 to get 1.

f < 1

The value of P(10) is 0.11 to ensure that the given distribution is a valid probability distribution.

To determine the value of P(10) so that the given distribution is valid, we need to ensure that the sum of all the probabilities equals 1.

Given:

X: 5, 10, 20, 30, 40, 50

P(X): 0.13, P(10), 0.11, 0.14, 0.21, 0.3

We know that the sum of the probabilities should be equal to 1.

Sum of probabilities = 0.13 + P(10) + 0.11 + 0.14 + 0.21 + 0.3

To find the value of P(10), we can set up the equation:

0.13 + P(10) + 0.11 + 0.14 + 0.21 + 0.3 = 1

Simplifying the equation:

P(10) + 0.89 = 1

Subtracting 0.89 from both sides:

P(10) = 1 - 0.89

P(10) = 0.11

Answer:

\(-16 = \frac{m}{5} - 18\\2 = \frac{m}{5}\\10 = m\\\)

Step-by-step explanation:

Given the equation \(-16 = \frac{m}{5} - 18\) isolate \(m\)

 1.  The first is sum both sides by 18

   \(-16 + 18= \frac{m}{5} - 18 + 18\\2 = \frac{m}{5}\)

 2. The second is multiply both sides by \(5\)

   \(5 \cdot 2 =5 \cdot \frac{m}{5}\\10 = m\)

So of this way you can proof that \(m = 10\)

Answer:

\(x=4\)

Step-by-step explanation:

Given \(\displaystyle\\\sqrt{x+12}-\sqrt{2x+1}=1\), start by squaring both sides to work towards isolating \(x\):

\(\displaystyle\\\left(\sqrt{x+12}-\sqrt{2x+1}\right)^2=\left(1\right)^2\)

Recall \((a-b)^2=a^2-2ab+b^2\) and \(\sqrt{a}\cdot \sqrt{b}=\sqrt{a\cdot b}\):

\(\displaystyle\\\left(\sqrt{x+12}-\sqrt{2x+1}\right)^2=\left(1\right)^2\\\implies x+12-2\sqrt{(x+12)(2x+1)}+2x+1=1\)

Isolate the radical:

\(\displaystyle\\x+12-2\sqrt{(x+12)(2x+1)}+2x+1=1\\\implies -2\sqrt{(x+12)(2x+1)}=-3x-12\\\implies \sqrt{(x+12)(2x+1)}=\frac{-3x-12}{-2}\)

Square both sides:

\(\displaystyle\\(x+12)(2x+1)=\left(\frac{-3x-12}{-2}\right)^2\)

Expand using FOIL and \((a+b)^2=a^2+2ab+b^2\):

\(\displaystyle\\2x^2+25x+12=\frac{9}{4}x^2+18x+36\)

Move everything to one side to get a quadratic:

\(\displaystyle-\frac{1}{4}x^2+7x-24=0\)

Solving using the quadratic formula:

A quadratic in \(ax^2+bx+c\) has real solutions \(\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\). In \(\displaystyle-\frac{1}{4}x^2+7x-24\), assign values:

\(\displaystyle \\a=-\frac{1}{4}\\b=7\\c=-24\)

Solving yields:

\(\displaystyle\\x=\frac{-7\pm \sqrt{7^2-4\left(-\frac{1}{4}\right)\left(-24\right)}}{2\left(-\frac{1}{4}\right)}\\\\x=\frac{-7\pm \sqrt{25}}{-\frac{1}{2}}\\\\\begin{cases}x=\frac{-7+5}{-0.5}=\frac{-2}{-0.5}=\boxed{4}\\x=\frac{-7-5}{-0.5}=\frac{-12}{-0.5}=24 \:(\text{Extraneous})\end{cases}\)

Only \(x=4\) works when plugged in the original equation. Therefore, \(x=24\) is extraneous and the only solution is \(\boxed{x=4}\)
