C is the answer and expresses the terms
ladessa [460]3 years ago
7 0

Answer: Option C

Explanation: Here we have the equation: N = 7LH

If we want to isolate L in one side of the equation, the steps are the following ones:

N = 7LH

First, divide both sides by the number 7, this does not affect equality.

N/7 = (7LH)/7 = LH

Now, we divide both sides of the equation by H.

N/(7H) = LH/H = L

Now we have the equation L = N/(7H), this mean that the right option is C.

What is the molarity of a solution that contains 5.80 grams of nickel (ii) nitrate in 500. ml?
Rus_ich [418]

Answer:- 0.0634 M

Explanation:

molarity is defined as the number of moles of solute in 1 L of solution

molar mass of Ni(NO₃)₂ - 182.7 g/mol

number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol

number of moles in 500 mL - 0.0317 mol

therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L

molarity of the solution is - 0.0634 M

Identify which strategy is likely to result in the greatest increase in the San Joaquin kit fox population. Explain why the stra
STALIN [3.7K]

The strategy that is likely to result in the greatest increase in the San Joaquin kit fox population is strategy one.

<h3>Which change is said to be responsible for the decline of the kit fox population A?</h3>

Habitat destruction and fragmentation is known to be the factor that has led to  and has been identified as the most vital cause of the kit fox's decline and it is one that has threatens the species' consistent viability.

So, the  human intervention that would most likely protect and keep the kit fox populations is through the  Introduction of  a species that can be able to act as the new kit fox food source.

Hence, The strategy that is likely to result in the greatest increase in the San Joaquin kit fox population is strategy one.

15. For a random sample of n = 64, find the probability of a sample mean being
mart [117]

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

P(\bar x < 24.3)

To find the probability first we have to determine the z score which is

z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }

= 1.92

Now probability is

P(\bar x < 24.3) \\\\= P(z < 1.92)

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered
