Which correlation coefficient best represents a moderate relationship showing fewer anxiety symptoms in people who report higher

weqwewe [10]

Answer:

a) -0.5

Step-by-step explanation:

Correlation

Correlation is a technique that help us to find or define a relationship between two variables.

It is a measure of linear relationship between two quantities.

A positive correlation means that an increase in one quantity leads to an increase in another quantity

A negative correlation means with increase in one quantity the other quantity decreases.

Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.

Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.

Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5

Bianca needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the difference

Rina8888 [55]

Correct Answer: 4.5 cm²

Two triangles of different sizes make up the logo. We are to find the difference in the areas of these triangle. Smaller triangle has a base of 2 cm and height 6 cm. Larger triangle has the base of 3 cm and height 7 cm.

Area of the triangle = $\frac{1}{2}$ x Base x Height

So,
Area of smaller triangle = $\frac{1}{2} *(2)(6)=6$ cm²
Area of larger triangle = $\frac{1}{2} *(3)(7)=10.5$ cm²

The difference in the areas of triangles = 10.5 - 6 = 4.5 cm²
