Answer:

8

Step-by-step explanation:

The geometric mean of two numbers 14 and 6 is 2√21.

An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.

In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.

Given, Two numbers 14 and 6.

Now, 14×6 = 84.

Now, we have to take the square root of 84 as we have two numbers.

Therefore, The geometric mean of 14 and 6 is,

= √(84).

= 2√21.

Answer:

3,-2

Step-by-step explanation:

From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,

Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.

Slope :-

→ m = 3 - 0 / 0 - 1.5

→ m = 3/-1.5

→ m = -2

A

Step-by-step explanation:

Melanie is correct

85 x 0.35 = 29.75

85 - 29.75 = 55.25

Answer:

a. Melanie is correct

Step-by-step explanation:

35% of 85= 29.75

*Find this by finding 10% (move decimal place over) and five percent (half of ten percent) and add triple of 10% plus the 5% or look it up*

Subtract this from 85

85-29.75=

Answer:

Option 1:  V = pi(6)2(8)

Step-by-step explanation:  

This is because when we plug in the value given in the picture.  

Formula  

The way we write this is by using our  "r" which is 6. We plug in the 6 for "r" so the equation will look something like this:  

Then we will plug in our height "h", which is 8. So the equation will look something like this:  

So that's it. Very simple. Just remember to keep the formula in mind and you will get the hang of it.

Equation to calculate volume of solid is V = 6 × 8 × 7

An equation is a formula that expresses equality by connecting two expressions with an equal sign =. Equation consists of variables, constants and coefficients. Right side and left side of an equation are in equality.

There are different types of equations as linear equations, quadratic equation etc.

example: 2x + 5y + 7 = 0 is an equation

here, 2, 5 are coefficients of variables x and y, 7 is a constant value

2x² + 5x + 3 = 0 is a quadratic equation.

Given,

measurement of the sides of solid

length = 6in

Width = 8 in

Height = 7 in

Volume = Length×Width×Height

V = 6 × 8 × 7

Volume = 336 in³

Hence, V = 6 × 8 × 7 is the equation to calculate volume of solid.

Answer:

Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Step-by-step explanation:

Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:

[tex]0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}}[/tex] (1)

Donde:

[tex]m_{A}[/tex] - Masa de la solución al 20 %, en onzas.

[tex]m_{B}[/tex] - Masa de la solución al 40 %, en onzas.

Podemos simplificar la formula como sigue:

[tex]0.2\cdot x + 0.4\cdot (1-x) = 0.34[/tex] (2)

Donde [tex]x[/tex] es la proporción de la solución al 20 % dentro de la solución final, sin unidades.

Ahora resolvemos para [tex]x[/tex] en (2):

[tex]0.4-0.2\cdot x = 0.34[/tex]

[tex]0.2\cdot x = 0.06[/tex]

[tex]x = \frac{0.06}{0.2}[/tex]

[tex]x = 0.3[/tex]

Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Answer: 28

Step-by-step explanation: Mean will be the average of all your numbers divided by the amount of numbers you have. So

24+24+12+52=112

Now since you have 4 numbers divide 112 by 4

So your mean is 28

Answer:

number 9 is A

number 10 is C

Step-by-step explanation:

number 9, rotate triangle

number 10, add the numbers/sides

The sample space (total number of students) = 30

total number of freshmen = 7

the freshmen = the event considered

.....therefore

probability = 7/30

%probability = 7/30 × 100%

= 23.33% ~ 23%

The solution is, The required probability is 3/4= 75%, is the probability the student is a freshman.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

here, we have,

We have to compute the probability,

P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.

Determine the total number of juniors.

Juniors=2+6=8

Since the number of females who are junior is 6, determine the required probability.

P(Female|Junior)=6/8

=3/4

=75%

Therefore, the required probability is 3/4 = 75%.

O no, because people in the bookstore are interested in purchasing books, so they do  not represent all shoppers in the mall

Step-by-step explanation:

In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.

Doing this, would help to give an accurate representation of both group in the survey.

Answer:

A. - 2

Step-by-step explanation:

Given

2/3 ( 6 - 9x) = 16

or, 6 - 9x = 16 * 3 / 2

or, 6 - 9x = 24

or, - 9x = 24 - 6

- 9x = 18

x = 18 / - 9

Therefore x = - 2
