Answer:
No
Step-by-step explanation:
The total number of trains is 287 + 54 + 17 + 5 = 363.
Of these, the number of trains that arrived no more than 10 minutes late is 287 + 54 = 341.
The proportion is p = 341/363 = 0.94.
94% of the trains arrived no more than 10 minutes late, so the company did not meet its target.
Answer:
4
Step-by-step explanation:
okay, so she rode 3 miles. Keep that aside
Then she had 2 walk the remaining 2 miles
She had to walk all the way home. So say for example instead of riding she walked 3 miles, then she walked that additional 2 miles. So, 5 miles. Then add the two miles she had to walk to his house. so, she walked 7 miles and rode 3 miles. 7-3= <em>4</em> miles. I attached a picture that should hopefully explain it better.
Hope this helps!
Answer:
The equation of the line is y = 2x + 6
According to the 3:1 ratio, you expect, out of a population of 1000 people, 750 non-hemophilia and 250 hemophilia.
The chi-square value can be calculated by the formula:
where:
O = observed value = 210
E = expected value = 250
Therefore:
χ² = (210 - 250)² / 250
= 6.4
Now, look at a χ<span>² distribution table, in order to find the p-value. In this case, you have only 1 degree of freedom and the closest </span>χ<span>² is 6.6 which corresponds to a p-value of 0.01.
Since p < 0.05, which is the minimum value generally accepted, we can say that the data do not support the hypothesis.</span>
Number name is the same as word form
8.542 = eight and five hundred fourty-two thousandths.
