Solution:

1)

Statement                                                     Reason

x  ║t                                                             Given

m∠16=m∠7                                                  Given

m∠16=m∠1                                                   Corresponding angles

m∠7=m∠1                                                      Substitution

k║w                                                               Alternate exterior angles equal

                                                                    (Property of parallel lines)


2)Part A:

Sum of angles in any triangle is 180 degrees.

m∠BAC+m∠ABC+m∠BCA= 180

Substituting the values :

4x+10+12x-6+3x+5=180

Adding like terms :

19x+9=180

19x=171

x=9.

Part B:

Substituting x value :

m∠BAC=4x+10=4(9)+10=46

m∠ABC=12x-6=12(9)-6=102

m∠BCA=3x+5=3(9)+5=32.

Part C:

m∠1=180-46=134

m∠2=180-102=78.

m∠3=180-32=148.

Part D:

Angle BAC and angle FAC are angle made on straight line and are linear .Such angles are called linear pairs.

Part E:

Angle BCE and Angle DCA are vertically opposite angles.

Assume that when Human Resource managers are randomly selected, 62% say job applicants should follow up within two weeks. If 25
stellarik [79]

Using the binomial distribution, it is found that there is a 0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

<h3>What is the binomial distribution formula?</h3>

The formula is:

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

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

The values of the parameters are given as follows:

n = 25, p = 0.62.

The probability that exactly 18 of them say job applicants should follow up within two weeks is P(X = 18), hence:

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

P(X = 18) = C_{25,18}.(0.62)^{18}.(0.38)^{7} = 0.1008

0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the tria
Dmitry [639]

Answer:

square root of 7

Step-by-step explanation:

Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that

a² + b² = c²

where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.

Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that

a² + 3² = 4

where a is the length in units, of the other leg of the triangle

a² = 4² - 3

a² = 16 - 9

= 7

a = √7

nalin [4]
Here is your answer

B) 1/125

REASON:

Given,

F (x)={(1/5)}^{x}

for F (3)

Putting x=3, in above function we get

F (3)= {(1/5)}^{3}= 1/125
