How to solve for b in the following equation... 53.2=30.5b^50

Mathematics
1 answer:
Margarita [4]4 years ago
7 0

Answer:

  b = (53.2/30.5)^(1/50) ≈ 1.011188765

Step-by-step explanation:

Divide by the coefficient of the variable, then take the 50th root.

  53.2/30.5 = b^50

  (53.2/30.5)^(1/50) = b . . . . . . 50th root of both sides of the equation

__

You know the rule of exponents for powers of powers is ...

  (a^b)^c = a^(bc)

If we want bc = 1, then we must have c = 1/b.

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator. 16 min to 72 min​
telo118 [61]

Answer:

2/9

Step-by-step explanation:

16/72 is the same thing as 2/9, just simplified. If you make 16 to 72 in a fraction you get 16/72. You divide them with their GCF which is 8. 16 divided by 8 is 2 and 72 divided by 8 is 9. Therefore the answer is 2/9.

According to a poll, 55 % of Americans do not know that GOP stands for Grand Old Party (Time, October 17, 2011). Assume that thi
Ivenika [448]

Answer:

\hat p  \sim N (p , \sqrt{\frac{p(1-p)}{n}})

The mean is given by:

\mu_{\hat p} = 0.55

And the deviation:

\sigma_{\hat p} =\sqrt{\frac{0.55*(1-0.55)}{953}}= 0.0161

Step-by-step explanation:

For this case we assume that the true population proportion of Americans do not know that GOP stands for Grand Old Party is 0.55 and we select a random sample of n = 953 americans

For this case we assume that we satisfy the conditions to use the normal approximation for \hat p

1) np >10 , n(1-p)>10

2) Independence

3) Random sample

4) The sample size is less than 10% of the population size

We assume that all the conditions are satisfied and the distribution for \hat p would be:

\hat p  \sim N (p , \sqrt{\frac{p(1-p)}{n}})

The mean is given by:

\mu_{\hat p} = 0.55

And the deviation:

\sigma_{\hat p} =\sqrt{\frac{0.55*(1-0.55)}{953}}= 0.0161
