Your distance from lightning varies directly with the time it takes you to hear thunder. If you hear thunder 10 seconds after yo

Nikitich [7]

Answer:

y = 1/5x

Step-by-step explanation:

Here, we have a direct relationship between the distance from lightning and the time it takes to hear thunder

Let the distance from lightning be y and the time it takes to hear thunder be x

If k is the proportionality constant, then;

y = kx

Now, let’s calculate k , given x 10 seconds and y = 2 miles

2 = 10k

k = 2/10 = 1/5

So the equation for the given situation is;

y = 1/5x

Use a Venn diagram to answer.<br> If n(A) = 8, n(B) = 9 and n(An B) = 6, what is n(AUB)?

marin [14]

Answer:

$n(A \cup B) = 6$

Step-by-step explanation:

In Venn sets, we have that:

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

In which n is the number of elements that each set contains.

In this question:

$n(A) = 8, n(B) = 9, n(A \cap B) = 6$

So

$n(A \cup B) = n(A) + n(B) - n(A \cap B) = 8 + 9 - 6 = 17 - 6 = 11$

So

$n(A \cup B) = 6$

Answer:

The null hypothesis is $H_{0} = 4.3$ .

The alternate hypothesis is $H_{a} > 4.3$

Step-by-step explanation:

Null hypothesis:

The previously report, the known value.

Alternate hypothesis:

What is questioned(higher, lower, different,...) of the null hypothesis

Previously, an organization reported that teenagers spent an average of 4.3 hours per week, on average, on the phone.

This means that the null hypothesis is $H_{0} = 4.3$ .

The organization thinks that, currently, the mean is higher.

That is, higher than 4.3. So

The alternate hypothesis is $H_{a} > 4.3$
