A dataset has 1000 records and one variable with 5% of the values missing, spread randomly throughout the records in the variabl

satela [25.4K]

Answer:

Step-by-step explanation:

it is given that there is one variable with 1000 records

we have to find the records which is expected would be removed

it is given that one variable is missing with 5% that 0.05

we can find missing records by multiplying total number of records and the missing value with one variable

so the expected record removed will be =0.05×1000=50

We know the side relations of a right angled Triangle (that is Pythagoras therom)

now, let the missing side be x

Hypotenuse² = sum of squares of other legs

that is ~

$15 {}^{2} = 5 {}^{2} + {x}^{2}$

$225 = 25 + {x}^{2}$

${x}^{2} = 225 - 25$

${x}^{2} = 200$

$x = \sqrt[]{200}$

$x = 10 \sqrt{2}$

The correct choice is ~ B

If a + b ≤ 8 and a = 2, then b ≤ 5.Which of the following would be a counterexample?

sertanlavr [38]

Answer:

The correct counterexample is $b \leq 6$ .

Step-by-step explanation:

We proceed to demonstrate the validity of given implication by direct demonstration and use of our knowledge in algebra:

1) $a + b \leq 8$ Given.

2) $a = 2$ Given.

3) $2+b \leq 8$ 2) in 1)

4) $2 + b +(-2) \leq 8 +(-2)$ Compatibility with addition.

5) $b+[2+(-2)]\leq 6$ Commutative and associative properties/Definition of subtraction

6) $b \leq 6$ Existence of additive inverse/Modulative property/Result.

This contradicts what implies the given proposition. The correct counterexample is $b \leq 6$ .
