Answer:

x = 5

Step-by-step explanation:

{2}^{2x - 3}   + 52 = 180

{2}^{2x - 3 }  = 128

{2}^{2x - 3}  =  {2}^{7}

2x - 3 = 7

2x = 10

x = 5

PSYCHO15rus [73]

Answer:

(513.14, 860.36) is a 98% confidence interval for the true mean

Step-by-step explanation:

We have a small sample size of n = 15, the mean balance was \bar{x} = 686.75 with a standard deviation of s = 256.20. The confidence interval is given by \bar{x}\pm t_{\alpha/2}(\frac{s}{\sqrt{n}}) where t_{\alpha/2} is the 100(\alpha/2)th quantile of the t distribution with n-1=15-1=14 degrees of freedom. As we want a 100(1-\alpha)% = 98% confidence interval, we have that \alpha = 0.02 and the confidence interval is 686.75\pm t_{0.01}(\frac{256.20}{\sqrt{15}}) where t_{0.01} is the 1st quantile of the t distribution with 14 df, i.e., t_{0.01} = -2.6245. Then, we have 686.75\pm (-2.6245)(\frac{256.20}{\sqrt{15}}) and the 98% confidence interval is given by (513.1379, 860.3621)

After 4 days, a plant is measured to be 10 inches tall. Later, after a total of 20 days, then height is measured to be 18 inches
vesna_86 [32]

Given :

After 4 days, a plant is measured to be 10 inches tall.

Later, after a total of 20 days, then height is measured to be 18 inches.

To Find :

The rate of growth for the plant.

Solution :

We know, rate is given by :

Rat e=\dfrac{\text{Change in height}}{\text{Time taken}}\\\\Rate = \dfrac{18-10}{20-4}\\\\Rate = 0.5 \ inch/day

Therefore, rate of increase of height is 0.5 inch/day .

Hence, this is the required solution.
