The graph of a function f(x)=5to the power of x -5 contains the point (2,y) what is the value of y

Mila [183]

I believe this this the function.

$f(x) = {5}^{x - 5}$

then

$f(x) = {5}^{2 - 5}$

then

$f(x) = {5}^{ - 3}$

then

$y = \frac{1}{125}$

Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile

Llana [10]

Answer: 37

Step-by-step explanation:

Given : Significance level : $\alpha:1-0.98=0.02$

Critical value : $z_{\alpha/2}=z_{0.01}=2.33$

margin of error : E= 1 mile per gallon

Population standard deviation: $\sigma=2.6$ miles per gallon.

We know that when the population standard deviation is known then the formula to find the sample size is given by :

$n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2$

$n=(\dfrac{(2.33)\times 2.6}{1})^2=36.699364\approx37$ [Round to the next whole number.]

Hence, the required number of automobiles should be used in the test = 37

What is the answer for this question?

grandymaker [24]

Answer:

Step-by-step explanation:

$\frac{11\pi }{6}$ is in the fourth quadrant where tan < 0

The related acute angle = 2π - $\frac{11\pi }{6}$ = $\frac{\pi }{6}$

Hence

tan( $\frac{11\pi }{6}$ )

= - tan( $\frac{\pi }{6}$ )

= - $\frac{1}{\sqrt{3} }$

= - $\frac{1}{\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$

= - $\frac{\sqrt{3} }{3}$ → A
