Of course it is c. range would show the difference between the highest and lowest scores, there is no mode in her data set, and the median is the middle point of the data set

One of the tallest living men has a height of 236 cm. One of the tallest living women is 224 cm tall. Heights of men have a mean
Roman55 [17]

Answer:

A. The woman is relatively taller because the z score for her height is greater than the z score for the man​'s height.

Step-by-step explanation:

Whoever has the highest z-score, is taller relative to the population of the same gender.

The z-score of a value X in a set with mean \mu and standard deviation /sigma is given by:

Z = \frac{X - \mu}{\sigma}

Solution:

Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:

Z = \frac{X - \mu}{\sigma} = \frac{236-170}{6} = 11

Heights of women have a mean of 161 cm and a standard deviation of 5 cm.

One of the tallest living women is 224 cm tall. The z-score of the women's height is

Z = \frac{X - \mu}{\sigma} = \frac{224-161}{5} = 12.6

The women has a higher z-score, so she is relatively taller.

The correct answer is A

Can an equation with the variable on both sides be written as a two step equation
trapecia [35]

Answer:

·         Use properties of equality together to isolate variables and solve algebraic equations.

·         Use the properties of equality and the distributive property to solve equations containing parentheses, fractions, and/or decimals.

 

Introduction

 

There are some equations that you can solve in your head quickly. For example – what is the value of y in the equation 2y = 6? Chances are you didn’t need to get out a pencil and paper to calculate that y = 3. You only needed to do one thing to get the answer, divide 6 by 2.

 

Other equations are more complicated. Solving  without writing anything down is difficult! That’s because this equation contains not just a variable but also fractions and terms inside parentheses. This is a multi-step equation, one that takes several steps to solve. Although multi-step equations take more time and more operations, they can still be simplified and solved by applying basic algebraic rules.

 

Using Properties of Equalities

 

Remember that you can think of an equation as a balance scale, with the goal being to rewrite the equation so that it is easier to solve but still balanced. The addition property of equality and the multiplication property of equality explain how you can keep the scale, or the equation, balanced. Whenever you perform an operation to one side of the equation, if you perform the same exact operation to the other side, you’ll keep both sides of the equation equal.

 

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division.
