2. A nutritionist wants to collect data on how much caffeine the average American drinks per day. She has the following ideas for how she could obtain a sample:
a. Ask the first 20 adults who arrive at a grocery store after 10:00 a.m. about the average amount of caffeine they consume each day.
b. Every 30 minutes, ask the first adult who comes into a coffee shop about the average amount of caffeine they consume each day.​

Answer: I think it should be a: 1/4 inch

Step-by-step explanation:

Answer:

The possible coins are:

P = penny = $0.01

N = nickel = $0.05

D = dime = $0.10

Q = quarter = $0.25

H = half dollar = $0.50

We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)

Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X

We know that Adam has half as much money as Ben, this can be written as:

(A + B + C) = 3*X/2

The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.

For example, if X = $0.10

then:

(A + B + C) = $0.10*(3/2) = $0.15

We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.

if x = $0.50 then:

(A + B + C) = (3/2)*$0.50 = $0.75

Here we could have:

A = $0.50

B = $0.25

then: A + B = $0.75

But we still have the coin C.

If we take X = $0.25 then:

(A + B + C) = (3/2)*$0.25 = $0.375

We could round the right part to $0.40

then the coins in the left part would be:

A = $0.25

B = $0.10

C = $0.05

A + B + C =  $0.25 + $0.10 +  $0.05 = $0.40

This is a strech, but is the only thing we can make with the given problem.

Answer:

2488

Step-by-step explanation:

11 x 12 = 132

132 + 245 = 377

377 - 66=  311

311 x 8 = 2488

Answer:

Step-by-step explanation:

x=5

y=-5

Hence it lies in 4th quadrant.

x=r cos θ

5=r cos θ  ...(1)

y=r sin θ

-5 =r sin θ  ... (2)

square and add

(5)²+(-5)²=r²(sin ²θ  +cos ²θ  )

r²=25+25=50

r=±5√2

dividing

tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)

θ=135°,315°

so polar coordinates are (5√2,315°) and (-5√2,135°)

Answer:

  64/109 ≈ 0.5872

Step-by-step explanation:

41 + 23 = 64 of the events have outcome E.

An additional 35 + 10 = 45 do not.

The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.

  P(E) = 64/109 ≈ 0.5872

Answer:

$11.25

Step-by-step explanation:

You take the original cost and multiply it by 0.25 for 25%. You get 3.75. Then you subtract 3.75 from 15.00. The answer is $11.25

Answer:

105 degrees

Step-by-step explanation:

well if we take a look at this

we know for sure that every triangle must have a total angle measurement of 180 degrees

so if we take the information we have and we add those together

55 + 20

that will give us

75

then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it

180-75

giving us 105 degrees as the third measurement of the angle in the triangle

Answer:

the third measure is [tex]105[/tex]°

Step-by-step explanation:

All measures of a triangle add up to 180°

[tex]A+ B + C = 180[/tex]

[tex]20 + 55 + C = 180[/tex]

[tex]75 + C = 180[/tex]

[tex]C = 105[/tex]°

Answer:

m<5 = 75°

Step-by-step explanation:

16. Given:

m<1 = 75°; m<3 = 40°

Required:

m<5

Solution:

Since lines A and B are parallel, and m<1 corresponds to m<5, therefore,

m<1 = m<5 (corresponding angles are congruent)

m<1 = m<5 = 75°

m<5 = 75°

Step-by-step explanation:

Answer:

5. 1:6 2/5

6. 1:5

Step-by-step explanation:

5. each time in the table you multiply H by 6 2/5 ex.

column 4 , 100x6=600, 2/5 of 100 = 40 and the total is 640, so the contant of proprtionality is 6 2/5

6. in the table there is a point on 2:10 and can be simplified to 1:5 so for every minute 5 gallons of water will be used

hope this helps sorry if this inst what your looking for have a blessed day :)

A number line with a closed dot at -4 is shaded to the right. Option A is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Given inequality,
c – 12 ≥ –16

Add 12 on both sides
c ≥ -4

So the required number line would be as a closed dot at -4 and shaded to the right.

Thus, A number line with a closed dot at -4 is shaded to the right. Option A is correct.
