Answer:

Use employee identification numbers to randomly select 200 employees.

Step-by-step explanation:

In order to choose 200 random people for the survey, it shall be purely random and unbiased.

If we use employee identification numbers to randomly select 200 employees it would be completely random and an unbiased choice.

For all the other options, none of them are purely random.

Does anyone know this
Helen [10]

Answer:Answer:

13.0feet

Step-by-step explanation:

Given ΔDEF with ∠F=90°, the measure of ∠D=19°, and DE = 40 feet, since one of the angles of the triangle is 90°, the triangle is a right angled triangle as shown in the attachment.

Using SOH, CAH, TOA to get the unknown EF.

Since <D is opposite to side EF, EF will be the opposite while side DE will be the hypotenuse

Based on SOH:

Sin<D = Opposite/Hypotenuse

Sin<D = EF/DE

Sin19° = EF/40

EF = 40sin19°

EF = 13.0 feet to the nearest tenth of a foot

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven
Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

D = 25 + 0.3X

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

D = b + mx

Where

b = D\ intercept

m = slope

By comparing: D = 25 + 0.3X to D = b + mx

b = 25 and m = 0.3

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in D = 25 + 0.3X

D = 25 + 0.3 * 5

D = 25 + 1.5

D = 26.5

<em>The cost of 5 miles is $26</em>

Make use of the above explanation to solve the question

−6x + 14 &lt; −28 OR 9x + 15 ≤ −12. solve for x.
sasho [114]

Answer:

x>7 or x ≤ -3

Step-by-step explanation:

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).
