To subtract integers, all you have to do is change the sign on the integer that is to be subtracted. If both signs are positive, then our answer will be positive. If both signs are negative, then our answer will become negative. If the signs are different then you are going to want to subtract the smaller absolute value from the larger absolute value.
For example: 14 - (-8) = 14 + 8 = 22.

The endpoints of cd are c(3,-5) and D(7,9). The coordinates of the midpoint m of CD are

-BARSIC- [3]

Answer: M(5,2)

Step-by-step explanation:We use the midpoint rule:

We just have to find the arithmetic mean of the x and y-coordinates.

The endpoints of CD are given as C(3,−5) and D(7, 9).

We substitute these values to get:

Therefore the coordinates of the midpoint M of CD are (5,2) and if i'm not good at explaining here ya go :)

miss Akunina [59]

20 more women needs to join for the ratio to be 5:4.
7:2 = 45 people
45 decide 9=5people
7•5=35people (men)
7•2=10people (women)

35(men)
10+20=30(women)
35:30 = 5:4

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).
