Answer:

False

Step-by-step explanation:

Correlation measures the strength of the relation between two variables.

Further, Correlation is said to be positive if increasing/decreasing the one variable, also increases/decreases the values of another variable.

Correlation is said to be negative if increasing/decreasing the one variable, also decreases/increases the values of another variable.

Since we don't know here exists a positive correlation or negative correlation.

So here are two possible conditions:

The person who has Gum disease also has heart disease.

And, the person has Gum disease can never have heart disease.

Thus, the given statement is false.

Combine like terms to create an equivalent expression -3.6-1.9t+1.2+5.1t
uranmaximum [27]

Answer:

3.2t-2.4

Step-by-step explanation:

The polynomial given for simplification is:

-3.6-1.9t+1.2+5.1t

Now, we combine like terms using the commutative property of addition.

The commutative property of addition states that:

a+b=b+a

So, the order can be shuffled when we add terms.

The terms containing 't' are grouped together and the constant terms are grouped together. This gives,

-1.9t+5.1t+1.2-3.6

Now, we group them using associative property and converse of distributive property as:

(-1.9+5.1)t+(1.2-3.6)

Simplifying the above expression, we get:

(-1.9+5.1)t+(1.2-3.6)\\3.2t-2.4

Therefore, the simplified form is 3.2t-2.4

Solve the compound inequality.
larisa [96]

Answer:

Step-by-step explanation:

9 - 4x > = 5                         or               4(-1 + x) - 6 > = 2

-4x > = 5 - 9                                           -4 + 4x - 6 > = 2

-4x > = -4                                                4x - 10 > = 2

x < = -4/-4                                              4x > = 2 + 10  

x < = 1                                                    4x > = 12

                                                              x > = 12/4

                                                              x > = 3

answer is : B

Flying lessons cost $645 for an 8-hour course and $1425 for a 20-hour course. Both prices include a fixed insurance fee. a. Writ
Softa [21]

Answer:

Check Explanation

Step-by-step explanation:

a) Let the fixed insurance fee be A and the rate charged per hour be b

The equation for the cost, C, of flying lessons in terms of length, h, of the course in hours is given by

C = A + bh

b) The two points (h, C) given in the question are (8, 645) and (20, 1425)

c) To find the equation of the line passing through these two points,

equation of a straight line iS given by

y = mx + c (where m = slope of the line and c = intercept)

denoting hours (h) as x and Cost (C) as y

645 = 8m + c

1425 = 20m + c

Solving this simultaneous equation,

m = 65 dollars/hour and c = 125 dollars

The equation of the straight line is

y = 65x + 125

Written in the variables of the question,

C = 65h + 125

This shows that the fixed insurance fee, called A in part (a) = $125

And the rate charged per hour called b in part (a) = $65/hour

Hope this Helps!!!
