Answer:

Answer: 52.4 percent

Step-by-step explanation: So you'd want to subtract 7.80 from 16.40 to get 8.60. Then you'd multiply that by 100 which would give you 860. After you've done that you want to divide 860 by 16.40.

Answer:

  40 : 110

Step-by-step explanation:

There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...

  150/15 = 10

Then the division is ...

  4 : 11 = 10·4 : 10·11 = 40 : 110

_____

Alternate solution

Let x represent the larger share. Then the ratio is ...

  (150 -x) : x = 4 : 11

Cross-multiplying gives ...

  11(150 -x) = 4x

  1650 = 15x . . . . . add 11x, simplify

  110 = x . . . . . . . . . divide by 15; the larger share

  150-x = 150-110 = 40 . . . . . . the smaller share

The division is 40 : 110.

Answer:

  (-7, -3)

Step-by-step explanation:

The point is the weighted sum of the end point coordinates. The weights are the reverse of the adjacent segment proportions.

  P = (4(-10, -3) +3(-3, -3))/7 = (-40-9, -12-9)/7 = (-49, -21)/7

  P = (-7, -3)

The point that partitions the segment in the desired fashion is (-7, -3).

_____

Alternate solution

The given segment can be recognized as a horizontal segment of length 7. Then the desired point is 3 units from the first end, so at (-10+3, -3) = (-7, -3).

Answer:

Option (4)

Step-by-step explanation:

Jordan spent 5 hours studying for 3 test with equal amount of time studying for each test.

On the number line, there are 3 small segments between each number.

Every small segment will represent time = [tex]\frac{1}{3}[/tex] hours

Total number of small segments = 15

If Jordan takes 3 equal durations for the study of each test,

Total number of small segments for each test = [tex]\frac{15}{3}=5[/tex]

Now we can plot these points on the number line.

Further count the segments for the answer ( 1 hour plus 2 small segments)

= 1 + [tex]2\times \frac{1}{3}[/tex]

= [tex]1\frac{2}{3}[/tex]

Therefore, time given for studying each test = [tex]1\frac{2}{3}[/tex] hours

Option (4) will be the answer.

Step-by-step explanation:

if you draw the situation you get a right triangle with

hypothenuse Edelton Walton and the Park City as the vertex of the right angle

Michael went 38+25= 63 miles

Landon went the length of the hypothenuse so use Pythagorean theorem

√38²+25² ≅45.49miles

Michael went 63-45.5 ≅17.5 further

Answer:

c) 6000

Step-by-step explanation:

the car's value would be $6000 because in two years the car decrased by $6000. Divide that by 2, and get $3000. That's how much it decreases in one year. $9000-$3000=$6000

btw I can't help it the car's original value was $24,000

Answer:

872

Step-by-step explanation:

The predicted value of $16,348 for the car in 2014.

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

Given,

The car was purchased for $22,800 in 2010.

The value of the car was $14,100 in 2012.

The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:

depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)

= (22,800 - 14,100) / (22,800 * 2)

= 0.0798 or 7.98%

This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):

value after 4 years = purchase price x (1 - depreciation rate)⁴

= 22,800 x (1 - 0.0798)⁴

≈ 16,347.97

Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.

Answer:

The most is 3/4 and the least is 7/12

Step-by-step explanation:

Becasue the demonitaor have a facotr of 24 so if we convert them to ?/24 we can get our answer by doing this 7/12 -> 14/24, 5/8 --> 15/24, 3/4 --> 18/24

Observational study

Step-by-step explanation:

Observational studies usually requires the comparing the outcome or behavior of two or more subjects involved. In the scenario described above, the need to perform any experiment or simulation to make prediction. Once the polls is in progress, the outcome or result of the polls in polling centre's only need to be observed and noted.

Answer:

X=13

Step-by-step explanation:

Answer:

x=13

Step-by-step explanation:

21=8+x

Swap sides so that all variable terms are on the left hand side.

8+x=21

Subtract 8 from both sides.

x=21−8

Subtract 8 from 21 to get 13.

x=13

Answer:

1/7 ;

0.0034

Step-by-step explanation:

Given that:

X = 1/14, 1/7, 3/14

n = number of observations = 3

Since, probability of X is equally likely ;

P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3

The mean, m ;

Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)

= 1/42 + 1/21 + 3/42

= (1 + 2 + 3) / 42

= 6 / 42

= 1/7

The variance :

Σx²*p(x) - m²

((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2

= 0.0238095 - 0.0204081

= 0.0034014

= 0.0034

Answer:

There were 56 different choices for the five locations to apply the new ointment.

Step-by-step explanation:

The order of the locations in which the new ointment was applied is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices were there for the five locations to apply the new ointment

Five locations from a set of 8. So

[tex]C_{8,5} = \frac{8!}{5!(8-5)!} = 56[/tex]

There were 56 different choices for the five locations to apply the new ointment.
