What is 247,009 rounded to the nearest thousand place

A family spends 20% of its monthly income on fuel. If they spend $324 a month on fuel, which is their monthly income?

nasty-shy [4]

Your answer is $1620.

To solve this, first look at what we're given. $324 is spent a month on fuel, and fuel is 20% of their income. Therefore, $324 is 20% of the family's income per month.

Now, to solve this, we're looking for 100% of the family's income. 20% is 1/5 of 100%, so therefore $324 is 1/5 of the family's full income.

To get 100%, then multiply 20% by 5 to get 100%, and therefore multiply $324 by 5 to get the full income.

$324 * 5 = 1620, or your answer.

Good luck!

Esearchers believed that an increase in lean body mass is associated with an increase in maximal oxygen uptake. A scatterplot of

Dovator [93]

Answer:

The correct option is (D).

Step-by-step explanation:

The p-value is well defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was truly observed.

A small p-value (typically ≤ 0.05) specifies solid proof against the null hypothesis (H₀), so you discard H₀.

A large p-value (> 0.05) specifies fragile proof against the H₀, so you fail to discard H₀.

The hypothesis is defined as follows:

H₀: The slope of the regression line is 0, i.e. β = 0.

Hₐ: The slope of the regression line is greater than 0, i.e. β > 0.

A scatter-plot of the measurements taken from 18 randomly selected college athletes displayed a strong positive linear relationship between the two variables; lean body mass and maximal oxygen uptake.

The significance level of the test is, α = 0.05.

The p-value of the test is, p-value = 0.04

As the p-value = 0.04 < α = 0.05, we reject the null hypothesis.

So, it can be concluded that there is a statistical evidence of a relationship between lean body mass and maximal oxygen uptake for college athletes.

Since the scatter-plot shows a strong positive linear relationship, it implies that as the an increase in lean body mass causes an increase in maximal oxygen uptake for college athletes.

Thus, the correct option is (D).

Consider the following circle with center at point O.

Maurinko [17]

Answer:

Chord: RT (and RS and TU, but those are also diameters)

Diameter: RS or TU

Radii: OU, OS, OT, or OR

Step-by-step explanation:

Chord: A line segment joining two points on a curve. Doesn't have to cross the center. (AKA, they have to touch the outer edge of the circle.)

Diameter: Chord that crosses the center of the circle(All examples given above cross center O)
