Y=10x+100 what is the independent and dependent variable in this equation

valentina_108 [34]

Answer:

In this equation X is independent variable while Y is dependent variable.

Step-by-step explanation:

Equation:

Y=10x+100

Independent variable in math:

A variable in an equation that may have its value freely chosen without considering values of any other variable.

Dependent variable in math:

A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.

<u>According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.</u>

For example if x = 1, Y will be 110.

And if x = 10, Y will be 200.

The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with mean μ. You select

VLD [36.1K]

Answer: 60.93 < μ < 69.07

Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a <u>99% confidence interval</u> means we are 99% confident the true mean is between the lower and upper limits.

To find the interval, use

x± $z\frac{s}{\sqrt{n}}$

z is z-score related to the % of confidence level

In this case, a 99% confidence interval is 2.576

x is sample mean

Calculating:

$x=\frac{63+69+62+66}{4}$

x = 65

65± $2.576\frac{3.16}{\sqrt{4}}$

65±4.07

Confidence Interval: 60.93 < μ < 69.07

Meaning that we are 99% sure the population means is between 60.93 and 69.07.

Ifx=−8, evaluate the following expression:(x−2)(x+4)x(x+9)

tekilochka [14]

Answer:

= 40

Step-by-step explanation:

so if you mean x = -8

$(x - 2)(x + 4) \times (x + 9) \\$

$( - 8 - 2)( - 8 + 4) \times ( - 8 + 9)$

$( - 10)( - 4) \times 1$

$40 \times 1$

$40$
