In a school machine shop, 60% of all machine breakdowns occur on lathes and 15% occur on drill presses. Let E denote the event t

RSB [31]

Answer:

A. P(EC) = 0.4

B. P(E∪E) = 0.75

C. P(EC ∩ FC) = 0.25

Step-by-step explanation:

Let us calculate -:

we are given with - P(E) = 60 and P(F) =.15,

Thus , (a) $P(E^C)=1-P(E)$

$=1-0.6$

$=0.4$

(b) P(E∪F) = P(E) + P(F)

= 0.60 + 0.15

= 0.75

(c) $P(E^C$ ∩ $F^C)$ $=1-P(E$ ∪ $F)$

$=1-0.75$

= $0.25$

Hence , the answers are -A. P(EC) = 0.4 , B. P(E∪E) = 0.75 , C. P(EC ∩ FC) = 0.25.

Two angles are supplementary. The first angle measures 60°. What is the measurement of the second angle?

Dominik [7]

Supplementary angles add up to 180° so subtract 60 from 180 and you get 120°. The measurement of the second angle is 120<span>°

A business just took out a loan for $100,000 at 10% interest. If the business pays the loan off in three months, how much did th

Ratling [72]

Answer:

$2,500

Step-by-step explanation:

The amount the business pay in interest can be calculated using the sinple interest formula as shown:

Simple Interest = Principal × Rate × Time/100

Given Principal = $100,000 (Loan)

Rate = 10%

Time (in years) = 3months = 3/12 years

Substituting the parameters into the formula we will have;

SI = 100,000×10×3/12×100

SI = 1000×30/12

SI = 30,000/12

SI = $2,500

Therefore the business pays an interest of $2,500
