Mathematics
1 answer:
AlladinOne [14]3 years ago
6 0

Answer:

  • domain: all terms are defined for <em>all real numbers</em>
  • solution: x = 6

Step-by-step explanation:

Rewrite the equation as a single exponential. After taking the log, the solution becomes obvious.

5^{x-2}-7^{x-3}=7^{x-5}+11\cdot 5^{x-4}\\\\5^{x-2}-11\cdot 5^{x-4}=7^{x-3}+7^{x-5}\\\\5^{x-2}(1-11\cdot 5^{-2})=7^{x-3}(1+7^{-2})\\\\5^{x-2}\dfrac{14}{25}=7^{x-3}\dfrac{50}{49}\\\\1=\dfrac{2\cdot 7^{x-3}5^4}{2\cdot 5^{x-2}7^3}=\left(\dfrac{7}{5}\right)^{x-6}\\\\0=(x-6)\log(1.4)\\\\x=6

Suppose you obtain a chi-square statistic of 67.81. Are your results statistically significant if the critical value obtained fr
Svetach [21]

Answer:

Result is statistically significant.

Step-by-step explanation:

Given that :

Chisquare statistic, χ² = 67.81

Critical value for the distribution, χ²critical = 3.84

α = 0.05

The Decison region :

If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.

Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05

Competition for a new generation of computers is so intense that MicroTech has funded three separate design teams to create the
Damm [24]

Answer:

The probability that MicroTech will beat the competition with its new computers is 0.994

Step-by-step explanation:

Consider the provided information.

MicroTech has funded three separate design teams to create the new systems.

The Probability of team A will come up with acceptable design is 90% or 0.9

The Probability of team B will come up with acceptable design is 80% or 0.8

The Probability of team C will come up with acceptable design is 70% or 0.7  

The probability of non of them will be able to come up with acceptable design = (1-0.9)×(1-0.8)×(1-0.7) = 0.1×0.2×0.3 = 0.006

Thus, the probability that MicroTech will beat the competition with its new computers is:

1-0.006 = 0.994

Hence, the required probability is 0.994
