Answer: option D

Step-by-step explanation:

step 1: take 7-3(both have the variable x) and subtract it.

-a- -b= subtract then write the greater no.s sign

+a- +b= if the 1rst number is greater than the second, subtract and give

or make it a positive integer. if the 1rst no. is smaller than the second,

subtract then write the greater number's sign.

5. Determine whether each of the following statements is true or false a. 1 + 1 = 3 if and only if monkeys can fly. b. If birds

Anna35 [415]

Answer:

Part (A) True

Part (B) False

Part (C) True

Step-by-step explanation:

Consider the provided information.

If both the statements are either true or false then the biconditionals are true. Otherwise biconditionals are false.

Part (A) 1 + 1 = 3 if and only if monkeys can fly.

Consider the first statement: 1+1=3 (This is a False statement)

Consider the second statement: "monkeys can fly" (This is also a False statement)

True: First statement is false and the second statement is also false, Thus, making the biconditional true.

Part (B) If birds can fly, then 1 + 1 = 3.

Consider the first statement: "birds can fly" (This is true statement)

Consider the second statement: 1 + 1 = 3 (This is a False statement)

False: First statement is true, but second statement is false, making everything false.

Part (C) If 1 + 1= 3, then pigs can fly.

Consider the first statement: 1+1=3 (This is a False statement)

Consider the second statement: "pigs can fly" (This is also a False statement)

True: First statement is false and the second statement is also false, Thus, making the biconditional true.

As people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not. Males Enjoyed: 47 D

Norma-Jean [14]

Answer:

(B) a = 41%, b = 3%

Step-by-step explanation:

The result from the survey is given below:

$\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&47&13&60\\Female&53&3&56\\Total&100&16&116\end{array}\right|$

The second table is given as:

$\left|\begin{array}{c|c|c|c}&Enjoy&$Did not Enjoy&$Total\\--&--&--&--\\Male&a&11\%&\\Female&46\%&b&\\Total&&&100\end{array}\right|$

Now, from the first table

Total Number of Respondents =116

Therefore:

$\dfrac{47}{116}*100 \approx 41\%\\\dfrac{13}{116}*100 \approx 11\%\\\dfrac{53}{116}*100 \approx 46\%\\\dfrac{3}{116}*100 \approx 3\%$

Therefore:

a=41%

b=3%

The correct option is B.

A triangle has two sides that measure 4ft. and 3ft. Which could be the measure of the 3rd side?

Aneli [31]

In order to form a triangle, the third side must be at least greater than the difference of the other two sides
4 - 3 = 1 So the third side must be greater than 1 foot and the third side must be less than the sum of the other two sides
4 + 3 = 7 So, the third side must be less than 7

1 < third side < 7
