how to simplify y- 3/3 +12

Answer:

Probability of picking an even and then even number = [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Probability of picking a card with even number,

P(even 1) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex] = [tex]\frac{\text{even cards}}{\text{Total number of cards}}[/tex]

               = [tex]\frac{2}{4}[/tex]

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

Followed by picking a card which is even without putting the first card back.

So an even card is to be picked out of remaining 3 cards.

P(even 2) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]

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

Now probability of both events = P(even 1) × P(even 2)

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

= [tex]\frac{1}{6}[/tex]

Therefore, probability of both the events will be [tex]\frac{1}{6}[/tex].

Answer:

Width = 4.5

Length = 7.5

Step-by-step explanation:

The perimeter is two times the length plus two times the width.

So 2(x+3) + 2x = 24 is the equation to solve.

2x+6+2x = 24

4x = 24-6

4x = 18

x = 9/2= 4.5

So the width = 4.5

Length = 4.5+3 = 7.5

Answer:

Length = 7.5 and width =- 4.5.

Step-by-step explanation:

We have the equation:

P = 2L  + 2W   where P = perimeter, L = length and W = width.

Here P = 24, L = x + 3 and W = x

So plugging in the given values:

24 = 2(x + 3) + 2x

4x + 6 = 24

4x = 24 - 6 = 18

x = 4.5.

So  the dimension ar length = x + 3 = 7.5 and width = 4.5.

p = 7000 is the amount deposited, aka the principal

r = 0.15 is the decimal form of 15% interest rate

t = 2 is the number of years the money sits in the account

--------------

B = p*(1+r)^t

B = 7000*(1+0.15)^2

B = 7000*(1.15)^2

B = 7000*(1.3225)

B = 9257.50

Subtract off the deposited amount to get the interest earned

i = B - p = 9257.50 - 7000 = 2257.50

Answer:

1,590.7 cm^3

Step-by-step explanation:

First, separate this shape into two smaller shapes you can easily find the volume of. In this example, you can separate this figure into a cone and a half-sphere.

Find the volume of the cone using the formula: V=πr^2(h/3). The radius is 7 because 14cm is the diameter, and 17cm is the height. When you solve, you get 872.32 for the volume of this cone.

Then, find the volume of the half-sphere. The volume of a sphere can be found with the formula: V=4/3πr^3. The radius is, again, 7. Now divide this value in half because you only want to find the volume of a half-sphere. You should get 718.38 cm.

Now add the two volumes together to get 1,590.7 cubed centimeters.

Step-by-step explanation:

volume of hemisphere

given

r=d/2=14/2=7cm

V=2/3πr^3

V=2/3×π×7^3

V=2/3×π×343cm^3

V=2/3×1077.56

V=718.37cm^3

volume of cone

given

r=7cm

h=17cm

V=πr^2×h/3

V=π×7^2×17cm/3

V=π×49cm^2×17cm/3

V=π×833cm^3/3

V=2616.94/3

V=872.31cm^3

Total volume=718.37cm^3+872.31cm^3

=1590.68cm^3

The question above is not compleye because it lacks the diagram box the shipping box.

Find attached to this answer the diagram of the shipping box which contains the question and the appropriate options to choose from.

Answer:

1/32 cubic yards or 1/32 yards³ (yd³)

Step-by-step explanation:

Looking at the attached diagram, the shipping box has the shape of a cube.

Therefore, the volume of the shipping box is calculated as :

Length × Width × Height

Where the

Length = 1/2 yard

Width = 1/4 yard

Height = 1/4 yard

Volume of the shipping box = 1/2 yard × 1/4 yard × 1/4 yard

= 1/32 cubic yards or 1/32 yards³ (yd³)

Answer: 7 hundreds are in 700

Step-by-step explanation: because if you divide 700 by 100 it equals 7.

Answer:

A "fair" coin lands heads-up half of the time and "tails-up" half of the time.

For one flip, the probability of landing heads-up is 1/2.

Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.

So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.

Step-by-step explanation:

The probability that coin lands heads-up and the die shows a five is 0.083.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.

Given that, a person flip a coin and then roll a fair six-sided die.

The probability the coin lands heads-up is 1/2

The probability that die shows a five = 1/6

Now, the probability of an event = 1/2 × 1/6

= 1/12

= 0.083

Therefore, the probability that coin lands heads-up and the die shows a five is 0.083.

Answer:

n = 144

Step-by-step explanation:

          6 / n = 5/120

         6 * 120 = 5*n

               5n = 6*120

               5n = 720

                 n = 720/5

                 n = 144

Answer:

144

Step-by-step explanation:

you should use a proportion to do this to make it easier to solve.

[tex]\frac{6}{n} = \frac{5}{120}[/tex]

cross multiply the numbers

[tex]5n = 6*120[/tex]

[tex]5n = 720[/tex]

then divide  720 by 5

Answer:

The mean length is 3 ft

while the median length is 2.5 ft

Step-by-step explanation:

The mean length is the sum of the lengths divided by the count of the lengths.

Mathematically, that is;

(2 + 3 + 6 + 1.5 + 4.5 + 1)/6 = 18/6 = 3 ft

To calculate the median length, we first need to rearrange the lengths in increasing order

1, 1.5, 2, 3, 4.5, 6

Now, looking at these lengths, the middle lengths are 2ft and 3ft

we can add both together and divide by 2

That would be (2+3)/2 = 5/2 = 2.5 ft

Answer:

Step-by-step explanation:

Given the lengths of the pieces of lumber that a carpenter has as shown;

2 ft, 3 ft, 6 ft, 1.5 ft, 4.5 ft, 1 ft

3) The mean length is expressed as the ratio of the sum total of the lengths to the total amount of pieces of lumber given.

Mathematically; Mean ([tex]\overline x[/tex]) = [tex]\frac{\sum Xi}{N}[/tex]

Xi is the individual length

N is the total amount of pieces of lumber = 6pieces

[tex]\overline x = \frac{2+3+6+1.5+4.5+1}{6} \\\overline x = \frac{18}{6} \\\overline x = 3ft[/tex]

4) Median is the value at the middle of the given lengths after rearrangement. Rearrangement can either be ascending or descending.

Rearranging the data in ascending order we have;

1ft, 1.5ft, 2ft, 3ft, 4.5ft, 6ft

The two lengths at the middle are 2ft and 3ft. Taking the average of the two values since we cannot have 2 median values.

Median = 2+3/2

median = 2.5ft

Answer:

4.167%

Step-by-step explanation:

Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.

To find: percent error

Solution:

Predicted time = 23 minutes

Actual time = 24 minutes

Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.

Error = 24 - 23 = 1 minute

Percent error = (error/actual time) × 100

= 4.167%

Answer:

c ≈ 6.08 m

Step-by-step explanation:

Your question is how to solve for a missing side length of a triangle when given 2 sides length and an angle. The side length can be solved using the cosine rule . We use cosine rule to find the length of a side of a triangle when given two sides and an included angle.

The cosine rule formula for finding a side length are as follows

c² = a² + b² - 2ab cosC

b² = a² + c² - 2ac cosB

c² = a² + b² - 2ab cosC

Using cosine rule

c² = 4² + 3² - 2 × 4 × 3 cos 120°

c² = 16 + 9 - 24 cos 120°

c² = 25 - 24 (-0.5)

c² = 25 + 12

c² = 37

square root both sides

c = √37

c = 6.0827625303

c ≈ 6.08 m
