Distributive property that can be used to find the quotient of 36÷3

What is the value of x in the equation 3/4x+4=5/8

Radda [10]

$\frac{3x}{4} +4= \frac{5}{8}$
Multiply both sides by 8.
2(3x) + 8(4)= 5
6x+32=5
Subtract 32 from both sides
6x=-27
Divide both sides by 6.
x=-27/6
Simplify
x=-9/2

Answer: x=-9/2

What is an important difference between statistics andâ parameters?

Ilia_Sergeevich [38]

Answer:

A characteristic , usually unknown of the population.

Characteristic of the population , such as its mean ,variance and standard deviations are population Parameters .

An observed characteristic of a sample are known as statistics

Estimate the use of a sample characteristic (statistic) to guess or approximate a population characteristic (parameter)

Step-by-step explanation:

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-1

When a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

Example :-2

If the students of a certain school are given blood tests and the type of blood is of interest, then a descriptive representation.

Population:-

Population is consists of the total observation's with which we are concerned

The number of observations in the population is defined to be the size of the population

Sample:- A sample is a subset of population.

Samples are classified in two ways

Large sample : if the size of the sample n≥ 30 is called the large sample.

small sample: if the size of the sample n<30 is called the small sample.

Statistics uses different names and symbols to distinguish characteristics

of the population from those of a sample.

Parameters :-

A characteristic , usually unknown of the population.

Characteristic of the population , such as its mean ,variance and standard deviations are population Parameters .

In symbolically mean of the population parameter is denoted by μ

In symbolically variance of the population parameter is denoted by σ²

In symbolically standard deviation of the population parameter is denoted by σ

Statistic :-

An observed characteristic of a sample are known as statistics

Estimate the use of a sample characteristic (statistic) to guess or approximate a population characteristic (parameter)

In symbolically mean of the sample statistic is denoted by x⁻

In symbolically variance of the sample statistic is denoted by S²

In symbolically standard deviation of the statistic is denoted by S

1. You must apply the formula for calculate the volume of a cone and and the volume of a cylinder. Then, you must sum both volumes to obtain the volume on the figure attached.

2. Volume of the cone:

Vcone=1/3(πr²h)

π=3.14
r=4 mm/2
r=2 mm
h=3 mm

3. When you substitute the values above into the formula, you obtain:

Vcone=1/3(πr²h)
 Vcone=12.56 mm³

4. The volume of the cylinder is:

Vcylinder=πr²h

π=3.14
r=4 mm/2=2 mm
h=2 mm

5. When you substitute the values above into the formula, you obtain:

Vcylinder=25.12 mm³

6. The volume of the figure is:

Vt=Vcone+Vcylinder
Vt=12.56 mm³+25.12 mm³
Vt=37.68 mm³
