Describe how [2^3][2^-4] can be simplified

Damm [24]

Answer:

½ or 0.5

Explanation:

Remove the brackets: $\bold{2^{3} \ \times \ 2^-4}$

2³: 8

$\bold{2^-4: \ \frac{1}{16} }$ (Turn the fraction into a decimal to make the equation easier)

1 ÷ 16 = 0.0625

Multiply

8 · 0.0625 = 0.5 or ½

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)

Claire cut some apples into eighths. She and her friends ate all but 17 pieces. How many whole apples and parts of apples did sh

Fiesta28 [93]

So they had 17 left over and one Apple was cut into 8 slices. 8 goes into 17 2 times with one left over. So it would be 2 whole apples with 1 slice left over. So 17 slices converts to 2 wholes and 1 part (slice)
