Answer:
The answer is 80. If you multiply 40 x 3 it is 120 and 40 x 2 is 80 so 2/3 of 120 is 80 NOT 40
Strands of copper wire from a manufacturer are analyzed for strength and conductivity. The results from 100 strands are as follows: Strength High Low High conductivity 74 8 Low conductivity 15 3 a. If a strand is randomly selected, what is the probability that its conductivity is high and its strength is high
Answer:
0.74
Step-by-step explanation:
Given :
__________________ STRENGTH __
__________________High _ Low
High conductivity _____ 74 __ 8
Low conductivity _____ 15 ___ 3
Probability that conductivity is high and strength is high :
This the probability of High conductivity n High strength = P(High conductivity n High strength)
Probability = required outcome / Total possible outcomes
Required outcome = P(High conductivity n High strength) = 74 (from table)
Total possible outcomes = total sample size = 100
Hence,
P(High conductivity n High strength) = 74 / 100 = 0.74

· y = 3x - 7
Find the slope
Answer:
3
Step-by-step explanation:
the slope of an equation (y=mx+b) is always "m", or the coefficient right infront of x. in this case, y=3x-7, 3=m, -7=b. m is the slope, so the slope is 3.

gina practica
3/4
de hora de aeróbicos y
hora de máquinas en el gimnasio; si ella va a
gimnasio solamente los domingos durante un mes, ¿cuántas horas dedica a ejercitarse?
A pergunta não está bem formatada. No entanto, pelo que parece óbvio
Responda:
3 horas
Explicação passo a passo:
Fração de hora gasta por sessão = 3/4 horas por sessão
Se o exercício for feito apenas aos domingos
Número de domingos por mês = 4
Portanto, número de sessões = 4
Fração de horas por sessão * Número de sessões
3/4 * 4 = 3 horas
Portanto, 3 horas são dedicadas ao exercício por mês

Answer:
x = 19
Step-by-step explanation:
Corresponding sides are proportional.
full length/right segment = 36/20 = (x+5+30)/30
Multiplying by 30 gives ...

Which graph is generated by this table of values?
Answer:
y=3x-6
Step-by-step explanation:
use 2 of the points for y=a×x+b
we use (2,0) and (3,3) as an example
we get
0=2a+b & 3=3a+b
so
3-0=3a+b-(2a+b)
3=a
b=-6

Answer:
17.5
Step-by-step explanation:
Those angles are supplementary, in other words, they add up to 180°
To solve you set the expressions up to 180:
(5x - 30) + 7x = 180
12x - 30 = 180
12x = 210
x = 17.5
