5/12

Probability month starts with the letter J or M is 5/12

Computation:

Number of total month = 12

Number of month starts with the letter J or M = 5

Probability = Number of desired output ÷ Number of total output

Probability month starts with the letter J or M is = 5 / 12

Answer:

Rectangular area as a function of x :   A(x)  = 200*x  + 2*x²

A(max) = 5000 m²

Dimensions:

x = 50 m

l  = 100 m

Step-by-step explanation:

"x" is the length of the perpendicular side to the wall of the rectangular area to be fenced, and we call "l" the other side (parallel to the wall of the barn) then:

A(r) = x* l     and the perimeter of the rectangular shape is

P = 2*x + 2*l   but we won´t use any fencing material along the wll of the barn therefore

P  =  2*x + l       ⇒   200 = 2*x  + l      ⇒   l  = 200 - 2*x      (1)

And the rectangular area as a function of x is:

A(x)  = x * ( 200 - 2*x)  ⇒  A(x)  = 200*x  + 2*x²

Taking derivatives on both sides of the equation we get:

A´(x)  =  200 - 4*x     ⇒   A´= 0

Then    200 - 4*x  = 0     ⇒   4*x =  200   ⇒  x  = 50 m

We find the l value, plugging the value of x in equation (1)

l  = 200 - 2*x     ⇒ l = 200 - 2*50   ⇒  l = 100  m

A(max)  =  100*50

A(max)  = 5000 m²

Answer:

A. 1 cm will represent 300 metres in real life.

B. 2.5 inches will represent 15 miles on the road

Step-by-step explanation:

Part A.

The scale on the map is 1: 30000. This means that for every 1 unit drawn on the paper, it actually represents 30,000 units in real life.

To get the actual distance represented by 1 centimetre, we will first have to convert 1 cm to metre. this is because our answer is required in metres.

This will be 1 cm = 0.01 metres

We can no set up the relation.

if 1 unit represents 30,0000 units in real life

0.01 metres will represent x metres in real life.

This will be got by cross multiplying[tex]x= \frac{0.01 \times 30,000}{1}=300 metres[/tex]

it will represent 300 metres in real life.

Part B

following the same principle above, we can also set up a relation.

If 1 inch represents 6 miles

2.5 inches will represent x miles on the road.

cross multiplying, we will have

[tex]x= \frac{2.5 \times6}{1}= 15 miles[/tex]

2.5 inches will represent 15 miles on the road

Answer:

First, simplify each square root: √175 , is 175 divisible by a perfect square (other than 1)? So √175=√25×7=√25×√7=5√7 . We cannot further simplfy √7 so we'll simplify the other square

Step-by-step explanation:

5 square

The simplified form of √175 is 5√7.

Here, we have,

To simplify the square root of 175, we can look for perfect square factors of 175 that can be taken out of the square root.

The largest perfect square that divides 175 is 25, which is the square of 5.

So, we can write √175 as √(25 × 7).

Using the property of square roots (√a × √b = √(a × b)),

we can split the square root:

√(25 × 7) = √25 × √7

The square root of 25 is 5, so we have:

√175 = 5√7

Therefore, the simplified form of √175 is 5√7.

Answer:

The answer is 66 ways .

Step-by-step explanation:

You have to use Combination because it says choosing 10 out of 12 as the position is not important :

12C10 = 66 ways of arrangements

The number of different 10-person teams are 66.

A combination is a mathematical technique for determining the number of potential arrangements in a set of objects where the order of the selection is irrelevant. You can choose the components in any order in combinations. Permutations and combinations are often mistaken.

We have out of the 12 girls who tried out for the softball team, 10 will be chosen for the team.

Using Combination

C(n, r) = n!/ r! (n- r)!

Here n = 12, r= 10

So, C(12, 10)= 12! / 10! (12- 10)!

                   = 12 x 11 x 10! / 10! x 2

                   = 6 x 11

                   = 66

There are 66 10-person teams.

Option (3). 1571 in³

Step-by-step explanation:

Amount of cement required to fill the cement = Volume of the cone

Formula for the volume of the cone is

Volume = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r = radius of the cone

h = height of the cone

Volume = [tex]\frac{1}{3}\pi (10^{2})(15)[/tex]

             = [tex]\frac{1}{3}\pi (100)(15)[/tex]

             = [tex]\frac{1500\pi }{3}[/tex]

             = 500π

Answer:

3/20 or 15%

Step-by-step explanation:

Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.

To find the probability you need to multiply the two probabilities together.

3/5 times 1/4 is 3/20.

So your answer is 3/20 or 15%.

If there are 4 equal sides, you divide 56 by 4. That equals 14.

Answer:

The correct answer is 11 ft.

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. This means that the portion marked x+4 is the same length as the portion marked 2x-7; this gives us the equation x+4=2x-7.

Subtract x from each side:

x+4-x=2x-7-x

4=x-7.

Add 7 to both sides:

4+7=x-7+7

Rough guide: doubling time in years is 72/interest rate in per cent. 72/6 is 12 so it doubles every 12 years, so in 36 years it will double 3 times.

A=300(1+.06)^36 is the formula. Without rounding, A=$2444.18. That is doubling 3 times or increasing 8 fold (and a little more)

Step-by-step explanation:

Hope this helps. Stay healthy. No corona. Take Care

At the agre of 28 he had invested A=$2444.18.

The doubling time in years is 72/interest rate in per cent.

72/6 is 12 so it doubles every 12 years,

So, in 36 years it will double 3 times.

The formula of investment is

[tex]A=P(1+r)^{nt}[/tex]

[tex]A=300(1+.06)^{36}[/tex]

Without rounding, We get,

A=$2444.18.

That is doubling 3 times or increasing 8 fold.
