Answer:

There is no explanation so I guess 1 to 1?

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

cause it only has 3 in l side

The probability of a 3 showing on the dice would be equal to 1/6. the correct option is A.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that A fair,six sided dice is thrown once.

There are 6 possibilities and 3 is one of them so, probability of 3 is 1 out of 6,

The probability of a 3 showing on a six-sided dice is;

P(E)  = 1/6

Answer:

The weight of the 8th plant is 39lb

Step-by-step explanation:

Given:

Average Weight of 7 plants = 23lb

Average Weight of 8 plants = 25lb

Required:

Weight of the 8th plant

To solve this, the total weight of the initial 7 plants need to be calculated;

[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]

Substitute 23 for Average and 7 for Number of plants

[tex]23 = \frac{Sum-of-weights}{7}[/tex]

Multiply both sides by 7

[tex]7 * 23 = \frac{Sum-of-weights}{7} * 7[/tex]

[tex]161 = Sum-of-weights[/tex]

Hence, the 7 plants weigh 161

Represent the weight of the 8th plant with E

When the 8th plant is added;

The sum of the weight becomes 161 + E

And the number of plants becomes 8

The average is calculated as thus

[tex]Average = \frac{Sum-of-weights}{Number-of-Plants}[/tex]

[tex]25 = \frac{161 + E}{8}[/tex]

Multiply both sides by 8

[tex]8 * 25 = \frac{161 + E}{8} * 8[/tex]

[tex]200 = 161 + E[/tex]

Subtract 161 from both sides

[tex]200 -161 = 161 - 161 + E[/tex]

[tex]39 = E[/tex]

Reorder

[tex]E = 39[/tex]

Hence, the weight of the 8th plant is 39lb

BRO THE IMAGE FORMED IS CONGRUENT

Step-by-step explanation:

Answer:

They are congruent

Step-by-step explanation:

Figure C will still stay the same shape and size because there was no dilation involved in the process. The image of Figure C will be in quadrant 1 and rotated 270° clockwise. Congruent means it is the same shape and size. So our answer is "They are congruent".

Answer:

37.8

Step-by-step explanation:

The distance is the addition of all sides of the figure. Then, we need to find the length of the diagonal (d). To do that we have to make a right triangle with height (h) = 5 m. Given that the top length is 12 m and the bottom length is 15 m, the base (b) of the triangle is 15 - 12 = 3 m

Using Pythagorean theorem:

d² = h² + b²

d² = 5² + 3²

d = √34

d = 5.8 m

Therefore, the distance he will have walked is 5.8 + 12 + 15 + 5 = 37.8 meters

Answer:

4) 8^14

7) h^7

10) 29^8 over 10^8

Step-by-step explanation:

If the numbers have the same base, just add their exponents together. So 10 plus 4 is 14.

Same thing for the second problem, since you have the same base, just add the exponents together. 6 plus 1 is 7

The bases are the same so just add the exponents, 7 plus one is 8.

(-2.9)^8

Convert it into a fraction: -(29/10)^8

Raise the fraction to the power (8) and the numerator and denominator to that power: 29^8/10^8

Step-by-step explanation:

Data

Given that A, B, and C are collinear points and B is between A and C, then the addition of the measure of segments AB and BC must be equal to the measure of segment AC, that is:

AB + BC = AC

Replacing with data:

2x + (x - 2) = 28

3x - 2 = 28

3x = 28 + 2

x = 30/3

Answer:

The electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.

Answer:

x is equal to 16 degrees

Angle measures 62 degrees

Step-by-step explanation:

From Law of Sines:

XW/sin(∠Y) = WY/sin(∠X)

From the picture

XW = 8

WY = 8

∠X = 62°

Replacing into the equation:

8/sin(∠Y) = 8/sin(62°)

∠Y = 62°

Angle Y is also equal to:

∠Y = 4x - 2

62 = 4x - 2

62 + 2 = 4x

64/4 = x

16° = x

Answer: Yes

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a circle = π r^2

Reamed hole area = π 0.278^2= 0.242794846

Pin Area: π ([9/32]/2)^2= 0.062126221

Diameter = 2 radius  

Radius = diameter/2

Since

Hole Area > pin area

The pin will  fit into the reamed hole.

Answer:

[tex]Male = 80[/tex]%

[tex]Female = 20%[/tex]%

Step-by-step explanation:

Given

Annual Mean Salary = 1500

Annual Mean Salary (Male) = 1560

Annual Mean Salary (Female) = 1260

Required

Percentage of male and female employed

Represent male by m and female by 4

So, total employees = m + f

The mean of an observation is calculated as thus;

Mean = Summation of observation divided by number of  observations

For Male:

Annual Mean = Total Salary/Number of males

Recall that Annual Mean = 1560

Number of males = m;

The formula becomes

[tex]1560 = \frac{TotalSalary}{m}[/tex]

Multiply both sides by m

[tex]1560 * m = \frac{TotalSalary}{m} * m[/tex]

[tex]1560m = TotalSalary[/tex]

For Female:

Annual Mean = Total Salary/Number of females

Recall that Annual Mean = 1260

Number of females = f;

The formula becomes

[tex]1260 = \frac{TotalSalary}{f}[/tex]

Multiply both sides by f

[tex]1260 * f = \frac{TotalSalary}{f} * f[/tex]

[tex]1260f = TotalSalary[/tex]

Total Annual Salary = Annual Salary of Male + Annual Salary of Female

Total Annual Salary = 1560m + 1260f

The mean annual salary is calculated as thus;

Mean Annual Salary = Total Annual Salary/Total Employees

Recall that Total Employees = m + f and Mean Annual Salary = 1500

So, the formula becomes

[tex]1500 = \frac{1560m + 1260f}{m+f}[/tex]

Multiply both sides by m + f

[tex]1500(m+f) = \frac{1560m + 1260f}{m+f} * (m+f)[/tex]

[tex]1500(m+f) = 1560m + 1260f[/tex]

Open brackets

[tex]1500m+1500f- = 1560m + 1260f[/tex]

Collect like terms

[tex]1500f -1260f = 1560m - 1500m[/tex]

[tex]240f = 60m[/tex]

Divide through by 60

[tex]\frac{240f}{60} = \frac{60m}{60}[/tex]

[tex]4f = m[/tex]

Reorder

[tex]m = 4f[/tex]

At this point, the percentage male and female can be calculated;

Male = (Number of male/Total Employees) * 100%

[tex]Male = \frac{m}{m+f} * 100[/tex]%

Substitute 4f for m

[tex]Male = \frac{4f}{4f+f} * 100[/tex]%

[tex]Male = \frac{4f}{5f} * 100[/tex]%

[tex]Male = \frac{4}{5} * 100[/tex]%

[tex]Male = 0.8 * 100[/tex]%

[tex]Male = 80[/tex]%

If percentage of male = 80%

Percentage of Female = 100% - 80%

[tex]Female = 20%[/tex]%

Question:

What is the solution to the linear equation?

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Answer:

[tex]x = \frac{-5}{3}[/tex]

Step-by-step explanation:

Given

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Required

Simplify

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Add [tex]\frac{1}{2}[/tex] to both sides

[tex]x - \frac{2}{3}x - \frac{1}{2} + \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]

[tex]x - \frac{2}{3}x = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]

Subtract [tex]\frac{5}{6}x[/tex] from both sides

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{5}{6}x + \frac{1}{2} - \frac{5}{6}x[/tex]

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2} + \frac{5}{6}x- \frac{5}{6}x[/tex]

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2}[/tex]

Take LCMs

[tex]\frac{6x - 4x -5x}{6}= \frac{2+3}{6}[/tex]

[tex]\frac{-3x}{6}= \frac{5}{6}[/tex]

Multiply both sides by 6

[tex]6 * \frac{-3x}{6}= \frac{5}{6} * 6[/tex]

[tex]-3x= 5[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}= \frac{5}{-3}[/tex]

[tex]x = \frac{5}{-3}[/tex]

[tex]x = \frac{-5}{3}[/tex]
