In December 2004, a report based on the National Survey on Drug Use and Health estimated that 20% of all Americans aged 16 to 20

o-na [289]

Answer:

542

Step-by-step explanation:

We are required to find the sample size at 98% confidence interval in this question

E = 0.04

P* = 20% = 0.20

n = p* x (1-p)(Zα/2÷E)²

α = 1 - 0.98

= 0.02

To get Critical value

= 0.02/2 = 0.01

The critical value at 0.01 is 2.33

Inserting values into formula:

O.2 x 0.8(2.33/0.04)²

= 0.8 x 0.2 x 58.25²

= 542.89

The value of n must be an integer therefore the answer is 542.

Here is a system of linear equations:

marysya [2.9K]

5x+4y=16 y=3/5x-3

y=mx+b <------ slope-intercept form

5x+4y=16
-5x -5x
============
4y=-5x+16
--------------
4
============
y= -5/4+4

Slope is -5/4
y-intercept is 4

y=3/5x-3

slope is 3/5
y intercept is -3

I can't do the graph but I'm sure you can figure it out!
Hope I helped.

Which situation can be represented by this inequality? 50−3.50x>100−6x Select one: A. Daniel has a $50 Dunkin Donuts™ gift ca

VARVARA [1.3K]

Answer:

Option C is correct

Step-by-step explanation:

Given: inequality is $50-3.50x>100-6x$

To find: situation that can be represented by the given inequality

Solution:

Cost of Dunkin Donuts gift card with Daniel = $50

Amount spent by Daniel per day = $3.50

Cost of Dunkin Donuts gift card with David = $100

Amount spent by David per day = $6

Amount left with Daniel after x days = $\$(50-3.50x)$

Amount left with David after x days = $\$(100-6x)$

According to question,

Amount left with Daniel after x days > Amount left with David after x days

$50-3.50x>100-6x$

So, he inequality that satisfies the situation is $50-3.50x>100-6x$

Option C is correct
