(CO 1) In a normally distributed data set of how long customers stay in your store, the mean is 31.7 minutes and the standard deviation is 1.9 minutes. Within what range would you expect 95% of your customers to stay in your store

Answers

Answer 1

Answer:

The range is between 27.9 minutes and 35.5 minutes.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 31.7 minutes

Standard deviation = 1.9 minutes.

Within what range would you expect 95% of your customers to stay in your store

Within 2 standard deviations of the mean.

Lower bound: 31.7 - 2*1.9 = 27.9 minutes

Upper bound: 31.7 + 2*1.9 = 35.5 minutes

The range is between 27.9 minutes and 35.5 minutes.

Step-by-step explanation:

Have a nice day lol i just know things

The equation as a single logarithm is:

[tex]log[(x^2 - 16)/(x + 4)].[/tex]

Option C is the correct answer.

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the logarithmic identity,

log a - log b = log (a/b)

We can simplify the given expression as:

[tex]=log(x^2 - 16) - log(x + 4) \\= log[(x^2 - 16)/(x + 4)][/tex]

Therefore,

The equation as a single logarithm is:

[tex]log[(x^2 - 16)/(x + 4)].[/tex]

What is linear equation in two variables?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.

What is substitution method?

The method  in which, the value of one variable from one equation is substituted in the other equation. So that, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. This method is called substitution method.

According to the given question we have

A linear equation in two variable

h = 3p + 5

So, the value of h when p = 7

Substitute, p = 7  in h = 3p + 5

⇒ h = (3 × 7) + 5

⇒ h = 21 + 5

h = 26

Hence, the value of h will be 26, when p =7.

Step-by-step explanation:

got it right on my test

The required value of x for the given equation is about 1.71.

Equation:

Important information:

The given equation is [tex]10(1.5)^{3x}=80[/tex].

Divide both sides by 10.

[tex](1.5)^{3x}=\dfrac{80}{10}[/tex]

[tex](1.5)^{3x}=8[/tex]

Taking log on both sides, we get

[tex]\log (1.5)^{3x}=\log 2^3[/tex]

[tex]3x\log (1.5)=3\log 2[/tex]

Divide both sides by 3log(1.5).

[tex]x=\dfrac{3\log 2}{3\log 1.5}[/tex]

[tex]x=\dfrac{\log 2}{\log 1.5}[/tex]

[tex]x\approx 1.71[/tex]

Therefore, the required value of x for the given equation is about 1.71.

Point Q lies on ST , where point S is located at (-2, -6) and point T is located at (5,8).
If SQ: QT = 5: 2, where is point Q on ST ?
Select the point, and then select a place on the coordinate grid to plot point Q.

Answers

Answer: (3,4)

(X,Y) (X1- Y1)+ (X2- Y2)

The coordinate of point Q is (3,4).

What are coordinates?

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

Coordinate point Q can be given by interception formula that state

Coordinate a point with intercept m: n  and bounded by coordinate (x₁, y₁) and (x₂, y₂).

x = [m(x₂) + n(x₁)]/(m + n)

And,

y = [m(y₂) + n(y₁)]/(m + n)

So,

x = [5(5) + 2(-2)]/(5 + 2)

x = 3

Similarly

y = [5(8) + 2(-6)]/(5 + 2)

y = 4

Hence "The coordinate of point Q is (3,4)".

Answer:

Yes

Step-by-step explanation:

Multiplying an integer by 0.01 is the same as Dividing such as :

0.01 = 10^-2

100= 10

For instance :

A number, n = 5 is multiplied by 10^-2

5 * 0.01 = 0.05

Thus, divide the number, n by 100;

5 / 100 = 0.05
