Answer:

Step-by-step explanation:

The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.

The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.

From the given situation,

news article says that high school students are currently spending an average of 15 hours per week doing homework online. This is the null hypothesis.

H0: µ = 15 hours

You don't think this is an accurate estimate, although you're not sure whether the real value is higher or lower. This is the alternative hypothesis.

Ha : µ ≠ 15 hours

Melinda and Marcus each have a job. Melinda earns $12 an hour. She also receives a $75 weekly bonus.
Olenka [21]
According to given information,
Equation of Melinda Earning = 75 + 12x
Equation of Marcus Earning = 15x
Where, x = Number of hours they worked.

Now, we need to calculate when they will have same amount of money, so for that instance they shall equal to each other.
75 + 12x = 15x
15x - 12x = 75
3x = 75
x = 75/3
x = 25

After 25 hours, they will have the money = 15(25) = $375

So, your final answer is $375

Hope this helps!

A house increases in value from $30,000 to $120,000 over a period of 40 years. Solve by using the formula r = (F/P) to the 1/n p
shutvik [7]

Answer:

The rate at which the value of house increases in 40 years is 1.03  

Step-by-step explanation:

The initial value of house = P = $30,000

The final value of house = F = $120,000

The period for which the value increase = 40 years

Let the rate at which the value increases in 40 years = r%

<u>Now, According to question</u>

The final value of house after n years = The initial value of house × (rate)^{time}

i.r F = P × (r)^{n}

Or, r = (\frac{F}{P})^{\frac{1}{n}}

Or, r = (\frac{120,000}{30,000})^{\frac{1}{40}}

Or, r = 4^{\frac{1}{40}}

∴  r = 1.03

The rate at which the value increases in 40 years = r = 1.03

Hence,The rate at which the value of house increases in 40 years is 1.03  Answer
