Answer:11.4

Step-by-step explanation: Set up a proportion: [tex]\frac{15}{x}[/tex]=[tex]\frac{5}{3.8}[/tex]

To solve a proportion, multiply the numbers diagonal from each other, then divide by the last number. In this problem, we would multiply 15 and 3.8, which equals 57, then we would divide by 5. That is why the answer is 11.4.

The number of chocolate cookies that were sold is 22100.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Since the ratio of chocolate : vanilla is 2:1 and the charity sells 2210 boxes of cookies, the number of chocolate will be:

= 2/(2+1) × 2210 × 15

= 2/3 × 2210 × 15

Answer:

  A. 1/2

  D. -1/3

Step-by-step explanation:

You want to know the solutions to 6x² -x -1 = 0.

We can factor the equation as ...

  6x² -3x +2x -1 = 0

  3x(2x -1) +1(2x -1) = 0

  (3x +1)(2x -1) = 0

The solutions will make the factors zero:

  3x +1 = 0   ⇒   x = -1/3

  2x -1 = 0   ⇒   x = 1/2

The solutions are 1/2 and -1/3.

If Tina's score is in the 50th percentile and the grades were normally distributed, Tina's score on the exam is 78.

A percentile refers to the comparison score between a particular score and the scores of the rest of a group. It represents the percentage of scores that a specific score surpassed. For example, if the score of 75 points on a test is ranked in the 85th percentile, it implies that the score 75 is higher than 85% of the scores. The 50th percentile, which is also the median score implies that 50% of the score is below or above the average score in a normally distributed data. In the given situation, if the grades are normally distributed with a mean of 78, that implies that 50% of the scores are above 78 and 50% of the scores are below 78. The standard deviation in this case is irrelevant. As Tina’s score is at the 50th percentile, her score on the exam would be 78.

Answer:

2.375 inches

Step-by-step explanation:

Main Steps

1. Identifying important parts of the question

2. Solving the problem

Step 1. - Identifying important parts of the question

In the question, there is some extraneous information.  For instance, the question introduces the terms "diameter" and "loaded in shear" and "with a safety factor of 1.5".  However, given the information in the problem, and the question asked, it isn't necessary to know that it is "loaded in shear" means, or to know what a diameter is (since everything stays with diameters, and doesn't involve another dimension), and the problem gives the result that will satisfy "a safety factor of 1.5".

Sifting through the problem/question, these are the important parts:

- "to the nearest 1/8 inch" (meaning round to the nearest 1/8th of a unit)

- with "units of inches to 3 decimal places"

- The number to round is "2.4183 inches

Step 2. - Solving the Problem

To round to the nearest 1/8 inch, we can divide the number 2.4183 by 1/8.  

[tex]2.4183 \div(1/8)[/tex]

Recall that dividing by a fraction is the same as multiplying by the reciprocal

[tex]2.4183 * 8[/tex]

19.3464

So, there are approximately 19, one-eighth-inches in the measurement.  (Note that 19.3464 is closer to 19 than it is to 20).  To find the final rounded measurement, multiply 19 by 1/8

[tex]19 * (1/8)[/tex]

2.375 inches

So, the diameter of the bolt that should be used (if rounded to the nearest 1/8 inch, to allow for a factor of safety of 1.5) is 2.375 inches

The dimensions of the box of height 36in and the side of the square is 18in.

A topological measure of the size of an object's covering properties is its dimension. It is roughly the number of coordinates required to specify a point on the object.

Given that the u.s.post office will accept a box for shipment only if the sum of height and girth(the distance around of bottom) is at most 108 in.

We must first determine the box's dimensions.

Let s be the side of the square base and h be the height of the box

So , h + 4s = 108

H = 108 – 4s -----(1)

Volume = s^2 h

V = s^2(108-4s)

= 108s2 – 4s3

V’ = 216s – 12s2

Let v’ = 0

S[216-12s] = 0

216 – 12s = 0

12s = 216

S = 216/12

S = 18

V” = 216 – 24s for s =18

V” = 216 – 432

= -216(-ve)

Volume is maximum when s =18

So h= 108-72

=36 in

Therefore the dimensions of the box of height 36in and the side of the square is 18in.

The length of RT is 12 units.

What is length?

Distance is measured by length. Length is a quantity having the dimension distance in the International System of Quantities. Most measuring systems use a base unit for length from which all other units are derived. The metre is the basic unit of length in the International System of Units (SI). The greatest extended dimension of a stationary item is typically believed to be its length. This is not always the case, as it may depend on the location of the item. When there is a basis from which vertical measurements may be made, height is employed. When length is the greatest dimension, width or breadth generally relate to a lesser dimension.

In the question:

A circular pool is surrounded by a brick walkway 3 m wide.

The area of the walk- way is 198 m^2.

To find the Radius of the pool.

Now, According to the question:

"Area of the circle bounded by the outside edge of the walkway" minus "area of the pool" = "area of the walkway".

Let R = Radius of the pool

Area of the circle bounded by the outside edge of the walkway is:

[tex]\pi[/tex](R +3)^2

Area of the pool is:

[tex]\pi R^2[/tex]

Now, Our equation is:;

[tex]\pi[/tex](R +3)^2 - [tex]\pi R^2[/tex] = 198

[tex]\pi[/tex]((R+3)^2 - [tex]R^2[/tex]) = 198

Open the inner bracket :

[tex]\pi[/tex]([tex]R^2+6R+9-R^2[/tex]) = 198

[tex]\pi[/tex](6R +9) = 198

6R+9 = 198/[tex]\pi[/tex]

6R = 198/[tex]\pi[/tex] - 9

R = (198/[tex]\pi[/tex] - 9)/6

R = (198/(3.14) - 9)/6

R = (63.057 - 9)/6

The angle in radians and the sector area are 2/9 π and 804.248 m² respectively

A sector of a circle is the part of a circle made of the arc along with its two radii

Given:  angle = 40° and distance(r) = 48m

To convert the angle to radians, multiply the angle by π/180:

Angle in radian(α) = 40 x π/180  = 2/9 π radian         (Note: π = 180°)

The formula for sector area = (α×r²)/2

Thus, sector area = (2/9π × 48²)/2 = 804.248 m²

Therefore, the angle in radians is 2/9 π and the sector area is 804.248 m²

What is standard deviation?

A measurement of a data set's deviation from the mean is referred to as "standard deviation" (or ""). A low standard deviation means that the data are grouped around the mean, whereas a large standard deviation says that the data are more spread out..

For instance, the mean of the two integers 2, 7, 14, 22, 30 and 15, 15, 15, 14, 16 is the same. But the second is clearly more diffused.

Given:

Mean is 83.2 points, and

8 points is the standard deviation.

Consequently, the proportion is

P(82 ≤ x ≤ 89.2)

=P( 82- 83.2 / 8 ≤ z ≤ 89.2 - 83.2/8)

=P (0.75) - P(-0.15)

=0.7734 -(0.4404)

= 0.3330

So, the Proportion of exam results between 82 and 89.2 points is 0.3330.
