Answer:

$h = \log_{3}{a_h}$

Step-by-step explanation:

The formula for the nth term of a geometric sequence is

$a_{n} = a_{1}r^{n-1}$

a₀ = 1, r = 3, and n = h

So,

$a_{h} = 3^{h}$

$h = \log_{3}{a_h}$

$h = \log_{3}{6561} = 8$

Ur 2 angles, when added, form a line....so they are a linear pair that equals 180

5k - 3 + 9 + k = 180
6k + 6 = 180
6k = 180 - 6
6k = 174
k = 174/6
k = 29

The water content of a soil volume is measured four times gravimetrically by oven drying. The mean value of the water content is

expeople1 [14]

Answer:

99% confidence interval for the soil water content is determined by

(0.19474, 0.26926)

Step-by-step explanation:

Explanation:-

Given mean of the sample = 23.2% = 0.232

Given standard deviation of the sample = 1.0% =0.01

Given sample size 'n' =4

Degrees of freedom = n-1 =4-1 =3

critical value = 0.01

$t_{\frac{0.01}{2} } = t_{0.005} =7.4534$

99% confidence interval for the soil water content is determined by

$((x^{-} - t_{0.005} \frac{S.D}{\sqrt{n} } , (x^{-} + t_{0.005} \frac{S.D}{\sqrt{n} })$

$((0.232 - 7.4534\frac{0.01}{\sqrt{4} } , (0.232 + 7.4534 \frac{0.01}{\sqrt{4} })$

( 0.232 -0.03726 , 0.232 +0.03726)

(0.19474, 0.26926)

Final answer:-

99% confidence interval for the soil water content is determined by

(0.19474, 0.26926)

Convert 185 degrees Celsius to degrees Fahrenheit. Round your answer to the nearest degree

lakkis [162]

Hello! :3

Answer:

The Correct Answer is 365 °F

Step-by-step explanation:

The C to F formula is $(C ~x~ 9/5) + 32 = F$

When we do 185 for C in the formula, we get $(185 ~x~ 9/5) + 32 = F.$

To solve, $(185 ~x~ 9/5) + 32 = F.$ we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

$185~x~9=1665$
