Hello!

The probability that the number chosen is greater then 3 and odd is 2/8

There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8

Step-by-step explanation:

There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8

If you are only talking about the numbers that are actually greater then 3 as your population, it is 2/5 :)

(I would appreciate Brainliest, please and thanks)

If a number randomly chosen is greater than 3, the probability that the number is odd is 2/5

The set of numbers is given as:

Set =  {1, 2, 3, 4, 5, 6, 7, 8}.

The numbers greater than 3 are:

G3 =  {4, 5, 6, 7, 8}

The odd numbers greater than 3 are

OG3 =  {5, 7}

The required probability is then calculated using:

P = n(OG3)/n(G3)

This gives

P = 2/5

Hence, the probability is 2/5

Answer:

The difference in cost per mile is $0.94.

Step-by-step explanation:

Uber

7x = 20.37

x = $2.91 per mile

Lyft

4y = 15.4

y = $3.85 per mile

3.85 - 2.91 = 0.94

Hello.

To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.

20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)

15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)

3.85 - 2.91 = 0.94

The difference in cost per mile is $0.94

Complete question :

Tabby is building two models of the Eiffel Tower. The scale factor of Model 2 to Model 1 is 1/4

____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)

Height _______ 984 ______11.808 ____?

W of base ____ 328 _______? _______?

Answer:

Model 1 :

Width of Base = 328 * 0.012 = 3.936 inch

Model 2 :

Height = 11.808 * 4 = 47.232 inches

Width of base = 4 * 3.936 = 15.744 inches

Step-by-step explanation:

____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)

Height _______ 984 ______11.808 ____?

W of base ____ 328 _______? _______?

Scale factor of Model 2 to Model 1 is 1/4

Model 1 : Model 2

1 : 4

The scale factor of actual tower to model 1

984ft = 11.808 inches

Hence,

1 ft = 11.808 / 984

1 ft = 0.012 inch

Model 1 :

Width of Base = 328 * 0.012 = 3.936 inch

Since ;

Model 1 : Model 2 ; 1 / 4

1 : 4

Model 2 :

Height = 11.808 * 4 = 47.232 inches

Width of base = 4 * 3.936 = 15.744 inches

Answer:

[tex]\huge\boxed{130 \textdegree}[/tex]

Step-by-step explanation:

We can use a couple of angle relationships to find the missing angle.

1. All angles in a triangle add up to 180°

We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.

[tex]180-35-95\\\\180-130\\\\50[/tex]

So the other angle in the triangle is 50°.

2. The 50° angle and the missing angle are supplementary.

We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.

Since we know one, we can find the measure of the other.

[tex]180-50\\\\130[/tex]

So the missing angle is 130°.

Step-by-step explanation:

It is better to use the metric system, rather than the English system, in scientific measurement because,

The metric system uses one unit for each category of measurement.

A system of measurements is called the metric system. It is employed in calculations and research across the globe.

Measurements for length include millimeters (mm), decimeters (dm), centimeters (cm), meters (m), and kilometers (km).

A foot equals 30.48 cm, however, a popular 30 cm rule measures every 1 cm, therefore the metric system also provides more exact measurements.

The English system is in fact based on the metric system because they look for reference materials to get the measurements.

Step-by-step explanation:

Answer:

96 hours

Step-by-step explanation:

25 eyes - 2 hours

1200 eyes* - x hours

[tex]x = \frac{2 \times 1200}{25} [/tex]

[tex]x = 96[/tex]

*each student has 2 eyes. So 600 students have 600×2=1200 eyes.

It will take the nurse 48 hours to give eye tests to all 600 students in her school.

An expression is combination of variables, numbers and operators.

If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).

To give eye tests to all 600 students, the nurse will need to give 600 tests in total.

Using the rate of 12.5 tests per hour, we can set up a proportion:

12.5 tests / 1 hour = 600 tests / x hours

Apply Cross-multiplication

12.5 tests ×  x hours = 600 tests

Divide both sides by 12.5 tests

we get,  x hours = 600 tests / 12.5 tests per hour

x hours = 48 hours

Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.

Answer:

No because  [tex]a^2 + b^2 = b^2 + a^2[/tex]

Step-by-step explanation:

No it does not matter if you were given a or b because with the equation a²+b²=c² as long as you can substitute in two values you can solve for the unknown value. For example if you had triangle STU having hypotenuse as 41 and value a as 9 you would substitute in the values resulting in the equation 9²+b²=41² then you would solve the exponents 81+b²=1681 then you would subtract 81 having the equation now as b²=1600 then you would √b²=√1600 resulting in

b=40

you could solve that equation the same way if you had b=40 and c=42

Given:

Total amount for investment = $32000

Rate of interest for Stock A = 4%

Rate of interest for Stock B = 7%

Jim is hoping to earn $2,000 in interest.

To find:

The amount of investments in Stock A and Stock B.

Step-by-step explanation:

Let amount of investments in Stock A = $x

Amount of investments in Stock B = $y

Total amount for investment = $32000

[tex]x+y=32000[/tex]        ...(i)

Rate of interests in Stock A and Stock B are 4% and 7%. Total interests is $2000.

[tex]0.04x+0.07y=2000[/tex]           ...(ii)

From (i) and (ii), we get

[tex]0.04x+0.07(32000-x)=2000[/tex]

[tex]0.04x+2240-0.07x=2000[/tex]

[tex]-0.03x=2000-2240[/tex]

[tex]-0.03x=-240[/tex]

Divide both sides by -0.03.

[tex]x=\dfrac{-240}{-0.03}[/tex]

[tex]x=8000[/tex]

Put x=8000 in (i).

[tex]8000+y=32000[/tex]  

[tex]y=32000-8000[/tex]  

[tex]y=24000[/tex]  

Therefore, the amount of investments in Stock A and Stock B are $8000 and $24000 respectively.
