  • ok so
  • 16.(1+3) = 16 . 4 = 64
  • so let's solve them
  • A = (16 . 1) + (3 . 16) .. here it's right because we split the 6 on each number ... if you want a prove solve it (16 . 1 ) + (3 . 16 ) = 64
  • B = (3+1) . 16 = 4 . 16 = 64
  • C = (16 +3) . 1 = 19 . 1 = 19
  • D = 161 + 163 = 324

so A & B = 64 .... so yeah right A & B are the correct answers

<em><u>by</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>way</u></em><em><u> </u></em><em><u>i </u></em><em><u>multiplied</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>"</u></em><em><u>.</u></em><em><u>"</u></em><em><u> </u></em>

How can exponential and logarithmic functions be combined
natulia [17]
Well.. .not exactly what you're asking, but the relationship of them is 
{&#10;log_{{  a}}{{  b}}=y \iff {{  a}}^y={{  b}}\qquad\qquad &#10;%  exponential notation 2nd form&#10;{{  a}}^y={{  b}}\iff log_{{  a}}{{  b}}=y &#10;}

so... hmm to add some
for example  let's say   if\ 5^3=125\textit{ that can be written also as}&#10;\\ \quad \\&#10;log_5(125)=3

PLEASE HELP ME I BEG I WILL GIVE BRAINLIEST
ohaa [14]

Answer:

Mean = (2.2 + 2.4 + 2.5 + 2.5 + 2.6 + 2.7)/6 = 2.48

Standard deviation = √(summation(x - mean)²/n

n = 6

Summation(x - mean)² = (2.2 - 2.48)^2 + (2.4 - 2.48)^2 + (2.5 - 2.48)^2 + (2.5 - 2.48)^2 + (2.6 - 2.48)^2 + (2.7 - 2.48)^2 = 0.1484

Standard deviation = √(0.1484/6

s = 0.16

Standard error = s/√n = 0.16/√6 = 0.065

Part B

Confidence interval is written as sample mean ± margin of error

Margin of error = z × s/√n

Since sample size is small and population standard deviation is unknown, z for 98% confidence level would be the t score from the student t distribution table. Degree of freedom = n - 1 = 6 - 1 = 5

Therefore, z = 3.365

Margin of error = 3.365 × 0.16/√6 = 0.22

Confidence interval is 2.48 ± 0.22

Part C

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

H0: µ = 2.3

For the alternative hypothesis,

H1: µ > 2.3

This is a right tailed test

Since the number of samples is small and no population standard deviation is given, the distribution is a student's t.

Since n = 6

Degrees of freedom, df = n - 1 = 6 - 1 = 5

t = (x - µ)/(s/√n)

Where

x = sample mean = 2.48

µ = population mean = 2.3

s = samples standard deviation = 0.16

t = (2.48 - 2.3)/(0.16/√6) = 2.76

We would determine the p value using the t test calculator. It becomes

p = 0.02

Assuming significance level, alpha = 0.05.

Since alpha, 0.05 > than the p value, 0.02, then we would reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the mean absolute refractory period for all mice when subjected to the same treatment increased.
