Let d = {-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36} determine which of the following statements are true and which are false. a) vxe d, if x is odd then x> 0 [select] b) vx e d, if x is less than 0 then x is even [select] c) vxe d, if x is even then xs0 [select] d) vx e d, if the ones digit of x is 2, then the tens digit is 3 or 4 e) vx e d, if the ones digit of x is 6, then the tens digit is 1 or 2 [select]

if x is odd then x> 0 is true statement.

if x is odd then x> 0 is true statement.

if x is even then x≤0 is false statement.

If the ones digit of x is 2, then the tens digit is 3 or 4 is true statement.

if the ones digit of x is 6, then the tens digit is 1 or 2 is false statement.

Step-by-step explanation:

Consider the provided information.

D = {-48, -14, -8, 0, 1, 3, 16, 23, 26, 32, 36}

Part (A) if x is odd then x> 0

Here only even numbers are less than 0 that means the statement is true.

if x is odd then x> 0 is true statement.

Part (B) if x is less than 0 then x is even.

Here only even numbers are less than 0 that means the statement is true.

if x is odd then x> 0 is true statement.

Part (C) if x is even then x≤0

Here we can see that 16, 26, 32, 36 are even number and also greater than 0. Thus the statement is false.

if x is even then x≤0 is false statement.

Part (D) If the ones digit of x is 2, then the tens digit is 3 or 4.

There is only one number whose ones digit is 2. i.e. 32 also the tens digit of the number 32 is 3. Which makes the above statement true.

If the ones digit of x is 2, then the tens digit is 3 or 4 is true statement.

Part (E) if the ones digit of x is 6, then the tens digit is 1 or 2.

Numbers having ones digit 6 are: 16, 26 and 36

Here, the tens digits are 1, 2 and 3 which is contradict to our statement. Hence the provided statement is false.

if the ones digit of x is 6, then the tens digit is 1 or 2 is false statement.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

question: use the following table of a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km

answer: 42 km/h
