What happens when you split 2 adams

1 answer:

7 0

Do you mean "atom" by any chance? if so, splitting one atom can lead to different things. Nuclear fission, another way of saying the splitting of an atom, reduces the overall mass, causing the release of energy. I hope that's what you're looking for.

borishaifa [10]

Answer:

$3c-8$

Step-by-step explanation:

Let

c-------> the number of cookies in each batch

we know that

To find the total number of cookies, multiply the number of batches by the number of cookies in each batch

$3c$ ------> equation that represent the total number of cookies

If Anna ate $8$ cookies

then

The expression to know how many cookies Anna has left is equal to

$3c-8$

The attention span of children (ages 3 to 5) is claimed to be Normally distributed with a mean of 15 minutes and a standard devi

Agata [3.3K]

Answer:

If the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 15 minutes

Sample size, n = 10

Alpha, α = 0.05

Population standard deviation, σ = 4 minutes

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 15\text{ minutes}\\H_A: \mu > 15\text{ minutes}$

Since the population standard deviation is given, we use one-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Now, $z_{critical} \text{ at 0.05 level of significance for one tail} = 1.64$

Thus, we would reject the null hypothesis if the z-statistic is greater than this critical value.

Thus, we can write:

$z_{stat} = \displaystyle\frac{\bar{x} - 15}{\frac{4}{\sqrt{10}} } > 1.64\\\\\bar{x} - 15>1.64\times \frac{4}{\sqrt{10}}\\\bar{x} - 15>2.07\\\bar{x} > 15+2.07\\\bar{x} > 17.07$

Thus, the decision rule would be if the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.
