Hands of a clock suggest an angle whose measure is continually changing. How many degrees does a minute hand move through during
1 answer:
A clock has sixty minutes for every one rotation. One full rotation has 360°. Knowing this, we can set up a ratio:
So, for every 1 minute, a clock hand moves 6°.
Next, all we have to do is multiply the number of minutes by 6°:
So:
In 9 minutes, a clock-hand moves 54°
In 35 minutes, a clock-hand moves 210°
In 45 minutes, a clock-hand moves 270°
Hope this helps!

Answer:
The test statistics is
The critical value is
The null hypothesis is rejected
Step-by-step explanation:
From the question we are told that
The sample size for men is
The sample proportion of men that own a cat is
The sample size for women is
The sample proportion of women that own a cat is
The level of significance is
The null hypothesis is
The alternative hypothesis is
Generally the test statistic is mathematically represented as
=>
=>
The critical value of from the normal distribution table is
The p-value is obtained from the z-table ,the value is
=>
Given that the then we reject the null hypothesis
We are given the first term and the common difference.
So,
Using these values in the given equation, we get:
So, option C gives the correct answer.
