The population in the study are the people that are 71 years of age and older in the United States.

Population simply means the representative sample of a larger group. Here, the population in the study are the people that are 71 years of age and older.

Also, 0.097 is a statistic because it describes the proportion of the people that suffer from the disease for the sample of 856.

The technical conditions are that the sample should be collected from a normal distribution. In this case, since the sample size is large, then the sampling distribution of the sample means is normal.

Step-by-step explanation:

Answer:

y=-5x+35

Step-by-step explanation:

Use the formula y = mx + b

m = slope, so plug in -5 as the slope

To find x-intercept we set y=0

We want the x-intercept to be 7 so we can plug that into the equation too

0=-5(7)+b

Lastly solve for b and you get your answer

Which is y=-5x-35 :) hope this helps

Hi there !

100% - 89% = 11% (not federally owned)

Answer:

Step-by-step explanation:

Given the following 3 points:

x      y

-56   66

-42   58

-28    50

Check the slope of two line segments between the three points:

(58 - 66)/(-42 - (-56))

= -8/14

= -4/7

(50 - 58)/(-28 -(-42))

= -8/14

= -4/7

As the slopes are the same, the 3 points are on a straight line with slope of - 4/7:

y = -4x/7  + C

Substitute x = -28 , y = 50 into the equation

50 = -4(-28)/7  +  C

50 = 16 + C

C = 34

y = -4x/7  + 34

Y-intercept at x = 0:

= 34

Answer:

Second option from the top

Step-by-step explanation:

        First, let us simplify x + 2 < -3

x + 2 < -3

x + 2 - 2 < -3 - 2

x < -5

        Now we can more clearly see which graph is correct.

   -> Since we are using < / > and not ≤ / ≥ the dot will be opened and not closed. This rules out the first and third options.

   -> Next, we need the direction of the line. Since < is facing to the left, our line will also be going to the left.

   -> To satisfy all requirements, since all graphs start at -5 already, the correct answer is the second option from the top.

Answer:

it's the second one

Step-by-step explanation:

it's all just common knowledge

the sign is a less than sign so the sign is an open dot. That eliminated two options. And whatever way the less than sign is pointing is the way the arrow goes

Answer:

9.6 cm

Step-by-step explanation:

Since the shapes are similar, we can write a proportion. Let x be the length of MN.

9/12 = 7.2/x Write a proportion.

9x = 12(7.2) Use cross products.

9x = 86.4 Multiply.

x = 9.6 Divide both sides by 9.

Side MN is 9.6 cm.

Explanation:

Imagine you randomly selected n items to form a sample, and you did this 100 times. Each time doing a trial like this, we generate a confidence interval. We expect about 99 of those times to have a confidence interval containing the true value of μ. This is what it means when we say "We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ."

Answer:

21 feet

Step-by-step explanation:

12^2+x^2=20^2(Pythagorean theorem)

144+x^2=400

x^2=400-144

x^2=256

x=sqrt 256

x=16

y^2+12^2=13^2(Pythagorean theorem)

y^2+144=169

y^2=169-144

y^2=25

y=sqrt 25

y=5

distance between A and B=16+5

Answer:

$40.80

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percent, this is always done by simply dividing the percent, in this case, 20%, by 100%. So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

Second, you need to find out what 20% of your $34.00 meal cost is. This is always done by multiplying 0.20 by $34.00, or 0.20 x $34.00=$6.80. So, the amount of tip you are going to leave is $6.80.

This makes the total cost of your meal (to write on your charge slip or other payment)

$34.00 + $6.80 = $40.80.

Answer:

$40.80

Step-by-step explanation:

If you pay for the original cost of the dinner AND leave a 20% tip then the total amount paid will be 120% of the original cost (100% + 20% = 120%).

Convert 120% into a decimal:  120% = 120/100 = 1.2

So 120% of $34.00 = 1.2 × 34 = $40.80

Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value.

The number 42,316 is different from 61,432 because the digits are in different positions.

here, we have,

Veremos que el otro lado  del triangulo debe medir 20 metros.

Sabemos que para un triangulo rectangulo de catetos P y K, el area es:

A = P*K/2

En este caso, sabemos que el menor de los catetos mide 5 metros, entonces tenemos:

P = 5m

Y tambien sabemos que el area es de 50m^2, reemplazando eso en la ecuación de arriba obtenemos:

50m^2 = 5m*K/2

Ahora podemos resolver esto para K

(50m^2)/5m = K/2

10m = K/2

2*10m = K = 20m

El otro lado debe medir 20 metros.
