Answer:
length times width equals height
Answer:
E. The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.
Step-by-step explanation:
The entire population of Greek and Egyptian mathematicians was already measured by Amara. She can measure the actual difference in the mean. Therefore, she needn't use a confidence interval. It is mostly common for a researcher to be more interested in the difference between means than in the specific values of the means. The difference in sample means is used to compute the difference in population means.
Amara's sample is a random selection of Greek and Egyptian mathematicians. It is a smaller group drawn from the population that has the characteristics of the entire population. The observations and conclusions made against the sample data are attributed to the population. In this case, the entire position is measured.
A t-test is a type of inferential statistic used to determine if there is a significant difference between the means of two groups (Greek and Egyptian mathematicians) which may be related in certain features. It is mostly used when the data sets, like the data set recorded as the outcome from rolling a die 50 times, would follow a normal distribution and may have unknown variances. A t-test is used as a hypothesis testing tool, which allows testing of an assumption applicable to a population. Once the actual difference is known, a confidence interval should not be used.
Answer:
D because a unit vectored is a vectored with a unit of magnitude.
we use a unit vector when we only interested in the direction of the vector rather than the magnitude
Answer:
9:1
Step-by-step explanation:
90:10
find number both can be divided by(simplify)
90/10 10/10
9:1
A scenario that would best model the graph on Holly, her home, and school is:
- Holly was trying to get to school from home but fell ill when 4 miles from home.
- Holly waited to catch her breath and gain some strength.
- Holly reached school and reported her condition.
- The school allowed her to go home.
<h3>What happened Holly's journey to school?</h3>
As Holly was heading to school, she felt uneasy and had to wait for 10 mins to catch her breath.
After doing so, she then continued to school which was 6 miles from her home. When she got there, she went to the nurse's office.
She waited in school for 15 minutes and was then told to go home to rest and recuperate. She then made the journey back home in a car and arrived in 10 minutes.
