Answer: $x=1.91$

Step-by-step explanation:

Given the expression $4^{2x-5} =6^{-x+1}$ , apply logarithm to both sides. Then:

$log(4)^{2x-5} =log(6)^{-x+1}$

Remembert that according the the properties of logarithms:

$log(a)^n=nlog(a)$

Then:

$(2x-5)log(4)=(-x+1)log(6)$

Appy distributive property and solve for "x":

$2xlog(4)-5log(4)=-xlog(6)+log(6)\\2xlog(4)+xlog(6)=log(6)+5log(4)\\x(2log(4)+log(6))=log(6)+5log(4)\\\\x=\frac{log(6)+5log(4)}{2log(4)+log(6)}\\\\x=1.91$

Amy, a nature photographer, randomly sampled photographs she took within the last year. She wanted to find out how many of her p

Sveta_85 [38]

The Constructed confidence interval for the proportion of her photographs taken within the last year contained flowers is

$CI\ E(0.57,0.65)$

From the question we are told that:

The proportion of photographs that had flowers P= 0.61

Margin of error of M.E= 0.04

Generally, the equation for Confidence interval for proportion is mathematically given by

$CI=0.61 \pm 0.04$ P \pm M.E

Therefore Confidence interval is

$CI=0.61 \pm 0.04$

And can also be written as

$CI\ E((0.61+0.04),0.61-0.04))$

$CI\ E(0.57,0.65)$

In conclusion the Confidence interval is

$CI\ E(0.57,0.65)$
