A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}

A=500\left(1+\frac{0.07}{4}\right)^{4\cdot 1}\implies A=500(1.0175)^4\implies A\approx 535.92951564

slamgirl [31]

Answer:

175 \div 48 = 3.65

Step-by-step explanation:

so they get paid 175 in total for two days so 24 hours are in one day but we are looking for the hourly pay for two days so we use 48 as a dividing variable . so 175 divide by 48 is 3.65 so they get paid 3.65 per hour but if we have to round it out then 4 per hour

A simple random sample of 32 men from a normally distributed population results in a standard deviation of 12.9 beats per minute
krok68 [10]

Answer:

Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute

Step-by-step explanation:

The null hypothesis is basically the problem statement i.e

Pulse rates of men have a standard deviation equal to 10 beats per minute

Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

The alternate hypothesis will contradict or negate the null hypothesis i.e

H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
