Recent research suggests that depression significantly increases the risk of developing dementia later in life (BBC News, July 6, 2010). In a study involving 949 elderly persons, it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression.a. Choose the relevant population and the sample. (You may select more than one answer. Bold the answer(s) that are correct.)1. The sample consists of all elderly people.2. The sample consists of 949 elderly people.3. The population is all younger and elderly people.4. The population is all elderly people.b.

In a given circuit, the supplied voltage is 1.5 volts. One resistor is 3 ohms and the other is 2 ohms. Use Ohm's law to determine the current in the circuit.0.3 amps
1.5 amps
7.5 amps
3.3 amps

Answers

Ohm's law = V = $(I)/(R)$
So to apply for this values in the formula we have to find total resistance in the cuircuit.
So, $R_(1) + R_(2)$ = total resistance
3 + 2 = 5 ohms
Now, lets plug in the equations
1.5 = $(I)/(5)$ { multiplying both sides by 5 }
5 * 1.5 = I
7.5 = I

So correct option is C
I = 7.5 amps

Answer:

0.3

Step-by-step explanation:

The equation you use is I= $(V)/(R)$

V=volts

R=ohms

I=amps

You add up the ohms since there are more than one

3+2=5

so 5 ohms

the volts are 1.5

Plug in the numbers:

I= $(1.5)/(5)$

Solve it-

1.5 divided by 5 equals 0.3

Sooooooo...

The answer is: 0.3

What is an equation of the line that passes through the point (-4,8) and is parallel to the line x+y=6?

Answers

Answer:

y = -x + 4

Step-by-step explanation:

x + y = 6 => y = -x + 6

The line that parallel to y = -x + 6 has same slope so m = -1

Using coordinates (-4,8)

y = mx + b

8 = (-1)(-4) + b

8 = 4 + b

b = 4

then y = -x + 4

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is(x - 4)² + (y - 3)² = 25
(x - 2)² + (y - 4)² = 25
(x - 2)² + (y - 4)² = 100

Answers

The center of the circle is the midpoint of the diameter.

The 'x' coordinate of the midpoint is (1/2) (6 - 2) = 2
The 'y' coordinate of the midpoint is (1/2) (7 + 1) = 4
The center of the circle is the point (2, 4) .

The length of the diameter of the circle is the distance
between the endpoints of the diameter.

The distance between (-2, 1) and (6, 7) is

√ (8² + 6²)

   = √ (64 + 36)

   = √ 100 = 10 .

The radius of the circle is 1/2 of 10 = 5 .

Now, the equation of any circle is

(x - [x of the center])² + (y - [y of the center])² = (radius)² .

and we have all the numbers now.

(x - 2)² + (y - 4)² = (5)² .

I'm very happy to see that this equation is actually
one of the choices !   I'll bet you are too.

Answer:

$(x-2)^(2)+(y-4)^(2)=25$

During harvesting season at Florida Blue Farms, hand pickerscollect about 200 pounds of blueberries per day with a 95%
pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?

A (0.95h+200)(0.90+22000)

B 0.95(200h)+0.90(22000m)

C 200.95h+22000.90m

D (200h+0.95)(22000m+0.90)

Answers

The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is: $0.95(200h) + 0.90(22000m)$
