Amanda's jewelry box is in the shape of a cube that has 6 inche edges. What is the volume of Amanda's jewelry box?

Mekhanik [1.2K]

To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times, so 6 x 6 x 6 is just 216 in.

In a wildlife preserve, 45 ducks are captured, tagged, and released. Later, 200 ducks are examined, and two of them are tagged.

ser-zykov [4K]

Answer:

There are 243 ducks in the preserve.

Explanation:

Given:

In a wildlife preserve, 45 ducks are captured, tagged, and released.

Later, 200 ducks are examined, and two of them are tagged.

To Find:

To estimate how many ducks are in the preserve =?

Solution:

Now, we know that, out of 200 2 ducks are tagged, which means remaining 198 ducks are untagged.

Now, total ducks count = ducks with tags + ducks with out tag

Total ducks count = 45 + 198

Total ducks count = 243

Hence, there are 243 ducks in total.

vovangra [49]

Answer:

150$

Step-by-step explanation:

In order to find the answer to this question you must find twenty-five percent of two-hundred.

50% of 100 = 50

100% of 100 = 100

100% of 200 = 200

50% of 200 = 100

25% of 200 = 150

= 150$

Hope this helps.

Suppose that the neighboring cities of Tweed and Ledee are long-term rivals. Neal, who was born and raised in Tweed, is confiden

Makovka662 [10]

Complete Question

The option to the blank space are shown on the first uploaded image

Answer:

Neal's decision is to fail to reject the null hypothesis (p 0.066). There is no sufficient evidence to prove the claim that the average electricity consumption of all Ledee household is greater than , 854.28 kWh

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 854.11$

The sample size is $n = 65$

The sample mean is $\= x = 879.28 \ kWh$

The standard deviation is $\sigma = 133.29 \ kWh$

The level of significance is $\alpha = 0.05$

The null hypothesis is $H_o: \mu = 854.11$

The alternative hypothesis is $H_a : \mu > 854.11$

The t-statistics is $t = 1.522$

The p-value is $p-value = 0.066$

Now from the given data we can see that

$p-value < \alpha$

Generally when this is the case , we fail to reject the null hypothesis

So

Neal's decision is to fail to reject the null hypothesis (p 0.066). There is no sufficient evidence to prove the claim that the average electricity consumption of all Ledee household is greater than , 854.28 kWh
