PLEASE HELP ASAP!! WILL GIVE BRAINLIEST

Step-by-step explanation:

12) y = 4 + 7x

x = 3,-1

y = 4 + 7(3) = 25

13) y = x - 11

x = 72,

y = 72 - 11 = 61

14) y = 6x - 5

y = 6(-4) - 5 = -29

y = -11 (x = -1)

y = -5 (x = 0)

y = 13 (x = 3)

15) y = x + 1, each relation is a function

16) An = 22 + (n-1)11

A(2) = 22 + 1(11) = 33

A(5) = 22 + 4(11) = 66

Sarah deposits $600 in a savings account that pays 2.5% per year. What is the minimum number of years it would take for the amou

shutvik [7]

Here is the compound interest formula solved for years:
Years = {log(total) -log(Principal)} ÷ log(1 + rate)
Years = {log(800) - log(600)} ÷ log(1.025)
Years = {2.903089987 -2.7781512504} / 0.010723865392
Years = { 0.1249387366 } / 0.010723865392
 Years = 11.6505319708 
That's how many years it takes for the $600 to become exactly $800.00
The question specifically asks how long for the money to be MORE than $800.00?

So, if we enter 800.01 into the equation, then the answer is
Years = {log(800.01) - log(600)} ÷ log(1.025)
Years = {2.9030954156 -2.7781512504} / 0.010723865392
Years = 0.1249441652 / 0.010723865392
 Years = 11.6510381875

Samples of a cast aluminum part are classified on the basis of surface finish (in microinches) and edge finish. The results of 1

liubo4ka [24]

Answer:

a) P (A)= 88/102= 0.8627

(b) P (B)= 89/102= 0.8725

c) P (A`) = 14/102 = 0.1372

(d) P (A∩B) = 84/102 =0.8235

(e) P(AUB)= 93/102 = 0.9117

(f)P (A`UB) = 98/102= 0.96078

Step-by-step explanation:

edge

finish excellent good Total

(A )surface finish excellent 84 4 88

good ( B) ⇵ 5 9 14

Total 89 13 102

a) Upper P left-parenthesis Upper A right-parenthesis equals

P (A)= 88/102= 0.8627

All the elements of set A = 84+4= 88

(b) Upper P left-parenthesis Upper B right-parenthesis equals

P (B)= 89/102= 0.8725

All the elements of set B = 84+5= 89

c) Upper P left-parenthesis Upper A prime right-parenthesis equal

P (A`) = 14/102 = 0.1372

All the elements of Universal set U which are not elements of set A = 102- 88= 14

(d) Upper P left-parenthesis Upper A intersection Upper B right-parenthesis equals

P (A∩B) = 84/102 =0.8235

Only those elements of set A and set B which are common

(e) Upper P left-parenthesis Upper A union Upper B right-parenthesis equals

P(AUB)= 93/102 = 0.9117

Totalling elements of set A and B= 88+5= 93

(f) Upper P left-parenthesis Upper A prime union Upper B right-parenthesis equals

P (A`UB) = 98/102= 0.96078

All the elements of Universal set U which are not elements of set A and the elements of Set B = 5+9+ 84= 98
