Answer:

Step-by-step explanation:

ratio of length to breadth=4:3

let breadth be x m

4/3=12/x(do cross multiplication)

3*12=x*4

36=4x

36/4=x

9=x

therefore breadth= 6m

Answer:

0.2097 = 20.97% probability that your longest wait is less than 12 minutes

Step-by-step explanation:

To solve this question, we need to understand the uniform and the binomial distribution.

Uniform distribution:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distribution has two bounds, a and b, and the probability of finding a value lower than x is given by:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [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]

And p is the probability of X happening.

Probability of a single bus having a waiting time of less than 12 times:

Uniformly distributed on the interval [0, 15] means that [tex]a = 0, b = 15[/tex]

[tex]P(X < 12) = \frac{12 - 0}{15 - 0} = 0.8[/tex]

What is the probability that your longest wait is less than 12 minutes?

This is the probability that all 7 buses have waiting time less than 12 minutes, which is [tex]P(X = 7)[/tex] when [tex]n = 7[/tex], with [tex]p = 0.8[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 7) = C_{7,7}.(0.8)^{7}.(0.2)^{0} = 0.2097[/tex]

0.2097 = 20.97% probability that your longest wait is less than 12 minutes

Answer:

1/8 x 2 = 0.25 kilogram

7/8 x 2 = 1.75 kilogram

Step-by-step explanation:

Amount Jack gets = (Jack's ratio / sum of ratios) x total kilogram of honey to be shared

sum of ratios = 1 + 7 = 8

1/8 x 2 = 0.25 kilogram

Amount Jill gets = (Jill's ratio / sum of ratios) x total kilogram of honey to be shared

7/8 x 2 = 1.75

Answer:

TR = 3 units

Step-by-step explanation:

PR = 12 units

PS = 9 units

PU = PS = 9 units (tangents drawn from an external point are congruent)

RU = PR - PU

RU = 12 - 9

RU = 3 units

TR = RU = 3 units (tangents drawn form an external point of a circle)

TR = 3 units

Answer: 5/27

Step-by-step explanation:

1/9 + 2/27 = ?

1. Find the LCD (Least Common Denominator )

LCD: 27

2.Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD.

(1/9 x 3/3) + (2/27 + 1/1) =

3. Solve

3/ 27   + 2/27  =5/27

Hence, the answer is 5/27

Answer:

110 degrees

Step-by-step explanation:

the answer is 110 degrees

add up everything and subtract it by 360 to get 110.

plz dont report. Can I have brainliest. I need it.

Answer:

we will add all the sides

40+128+×+82=360

250+×=360

×=360-250

x=110

Answer:

118.0 in^3

Step-by-step explanation:

Answer:

The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: −5 = −5/1.

Answer:

Volume = 1299.5 ft³

Step-by-step explanation:

Given the following data;

Side length of the base = 18.1 ft

Height = 11.9 ft

To find the volume of pyramid with a square base,

Volume of square-based pyramid = A(h/3)

Where;

A is the area of the square base.

h is the height of the pyramid.

First of all, we would find the area of the square base;

Area of square = L²

A = 18.1²

A = 327.61 ft²

Next, we find the volume of the square-based pyramid;

Volume = 327.61(11.9/3)

Volume = 3898.559/3

Volume = 1299.5 ft³

Answer: lowercase= sides Uppercase= angles

A=104 degrees

a=13

B=49 degrees

b=10.11

C=27degrees

c=6.08

Step-by-step explanation:

B=180.00∘−A−C=180.00∘−104.00∘−27.00∘=49.00∘b=sin(B)⋅asin(A)=sin(49.00∘)⋅13.00sin(104.00∘)=10.11c=sin(C)⋅asin(A)=sin(27.00∘)⋅13.00sin(104.00∘)=6.08

Answer:

Answer:

The annual interest rate of return during his investment was 12.28%.

Step-by-step explanation:

Since Julio purchased 1,700 shares of a certain stock for $ 23,750 including commissions, and I have sold the shares 3 years later and received $ 32,500 after deducting commissions, to find the effective annual rate of return on his investment over the 3-year period the following calculation  must be performed:

23,750 = 100

32,500 = X

32,500 x 100 / 23,750 = X

3,250,000 / 23,750 = X

136.84 = X

(136.84 - 100) / 3 = X

36.84 / 3 = X

12.28 = X

Therefore, the annual interest rate of return during his investment was 12.28%.

Answer:

12x + 6t

Step-by-step explanation:

Since 3 is on the outside of the parentheses, multiply 3 times 4 to get 12 and 3 times 2 to get 6. Then put in the variable

Answer:

The expression would be: 12x + 6t

Step-by-step explanation:

Answer:

Solution given:

a = 12, b = 5, c = 9

We have

: a² = b² + c² – 2bc cos A

12²=5²+9²-2×5×9 cos A

12²-25-81=-90 cos A

cos A=38/-90

A=cos -1(-19/45)

A=115°
