Answer:

  ∠B ≈ 50.9°

Step-by-step explanation:

The area formula for a triangle can be used to find the missing angle.

We don't want confusion between A for area and angle A, so we define Q as the area of the triangle with sides a, c, and included angle B. In this scenario, 'a' represents side BC (opposite angle A), and 'c' represents side AB (opposite angle C).

  Q = (1/2)ac·sin(B)

Solving for B, we have ...

  2Q/(ac) = sin(B)

  B = arcsin(2Q/(ac)

  B = arcsin(2(64)/(11(15)) = arcsin(128/165)

  ∠B ≈ 50.9°

3 TIMES 2 DONT EQUAL 7

Step-by-step explanation:

[tex] \frac{2x}{5} + \frac{5}{8} = \frac{1}{4} [/tex]

[tex] \frac{2x}{5} = \frac{1}{4} - \frac{5}{8} [/tex]

[tex] \frac{2x}{5} = \frac{2}{8} - \frac{5}{8} [/tex]

[tex] \frac{2x}{5} = \frac{2 - 5}{8} [/tex]

[tex] \frac{2x}{5} = \frac{ - 3}{8} [/tex]

[tex]2x = \frac{ - 3}{8} \times 5[/tex]

[tex]2x = \frac{ - 15}{8} [/tex]

[tex]x = \frac{ - 15}{8} \div 2[/tex]

[tex] x = \frac{ - 15}{8} \times \frac{1}{2} [/tex]

[tex]x = - \frac{ 15}{16} [/tex]

Step-by-step explanation:

Given parameters

Percentage of all teachers the works in summer  = 85%

Number of teachers sampled  = 6 teachers

Unknown:

The probability that they all work in summer  = ?

Solution:

Now, to solve this problem, let us find the number of teachers that works in summer from the given size;

    Number of teachers = 85% x 6  = 5.1;

  Since it is not possible to have 5.1 people, the number of teachers will be 5

The probability  = [tex]\frac{5}{6}[/tex]

Answer: 4.7 ft

Step-by-step explanation:

Since this is a diameter we are going to do the formula that uses the diameter to find the circumference.

C=3.14(d)

1.) Insert the numbers into the formula: C= 3.14*1.5

You’ll get 4.71 as your answer.

Next round to the nearest tenth and you’ll get 4.7.

In this following excerpt,

We know that jamal wants to know the final mass, for this to be solved. We have to add the initial mass (11) to the change in the mass i.e, [-4] for this to be qualified as the final mass we are supposed to add the 11 to the -4, i.e, (11+(-4).)

Answer:

All in all the statement to support this resolution is,

11 + (-4)

Answer:

9x^2+42x+45

Step-by-step explanation:

Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.

Step-by-step explanation:

First we write the probability of 6V flashlight working representing it as a binomial mass function of a binomial random variable

P ( 6v flashlight working  ) = P ( at least one 6V battery works )

                                           = P ( 1 6v battery work )  + P ( 2  6v battery work )

                                           = b( 2; 2, p ) + b( 1; 2, p )

write out a formula of  b( 2; 2, p ) + b( 1; 2, p )

P ( 6v flashlight working  )  = p^2 + 2p( 1 - p )

Next we write the probability of D flashlight working representing it as a binomial mass function of a binomial random variable

P ( D flashlight works ) = p ( at least two D batteries works )

                                     = b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )

write out a formula of  b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )

P ( D flashlight works ) = [tex]P^4 + 4p^3 ( 1- p ) + 6p^2 ( 1- p)^2[/tex]

Answer:

-24.35, -7.96, 11.20

Step-by-step explanation:

Negative numbers are worth way less than positive numbers. In order to solve, the biggest looking negative number is worth less.

Positive is bigger

Negative is smaller

*EXTRA*

negative plus negative = positive

negative plus positive = negative

negative times negative = positive

negative times positive = negative

Answer:

1,2,3,4

Step-by-step explanation:

Answer:

Instructions are below.

Step-by-step explanation:

To calculate the final amount of a given substance, we need to use the following formula:

final amount= initial amount / (2^n)

n= elapsed time / half-life

For 20 years:

n= 20/10= 2

Final amount= 200/(2^2)

Final amount= 50 grams

For 60 years:

n= 60/10= 6

Final amount= 200/ (2^6)

Final amount= 3.125 grams

To calculate the elapsed time it is more complicated:

elapsed time= ln(ending amount/beginning amount) / (-decay constant)

ln= natural logarithm

decay constant= ln(2) / half-life

decay constant= 0.0693

elapsed time= ln(1.03/200) / (-0.0693)

elapsed time= 76.028

Prove:

n= 76.02/10= 7.602

Final amount= 200/(2^7.602)= 1.03 grams

Step-by-step explanation:

Answer:

Odd number: 13/25 (52%)

Multiples of 5: 5/25 (20%)

Step-by-step explanation:

There are 13 odd numbers between 1 and 25 so you have a 13/25 chance which is 52% (13/25 = 0.52). There are 5 multiples of 2 between 1 and 25 so you have a 5/25 chance which is 20% (5/25 = 0.2).

The probability of selecting an odd number or multiples of 5 is 3/5

"It is finding out the possibilities of the occurrence of an event."

"P(A) = n(A) / n(S)

where, n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment"

For given question,

A number is chosen at random from 1 to 25.

n(S) = 25

Let event A: selecting odd number

⇒ A = {1 , 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}

⇒ n(A) = 13

So, the probability of selecting odd number would be,

⇒ P(A) = n(A)/n(S)

⇒ P(A) = 13/25

Let event B: selecting a number which is multiple of 5

⇒ B ={5, 10, 15, 20, 25}

⇒ n(B) = 5

So, the probability of selecting a number which is multiple of 5 would be,

⇒ P(B) = n(B)/n(S)

⇒ P(B) = 5/25

Let (A ∩ B) represents the odd numbers which are multiple of 5

⇒  (A ∩ B) = {5, 15, 25}

⇒ n(A ∩ B) = 3

So, the probability of selecting odd numbers which are multiple of 5 would be,

⇒ P(A ∩ B) = n(A ∩ B)/n(S)

⇒ P(A ∩ B) = 3/25

So, the probability of selecting an odd number or multiples of 5 is,

⇒ P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

⇒ P(A ∪ B) = 13/25 + 5/25 - 3/25

⇒ P(A ∪ B) = 15/25

⇒ P(A ∪ B) = 3/5

Therefore, the probability of selecting an odd number or multiples of 5 is 3/5
