The answer is b for number 2 but for the first one I need to see the top of the first question and the last one
Answer:
4000inches
Step-by-step explanation:
1000*4 = 4000inches
The question asked about the values of x when y or g(x) is equal to zero. This is similar to asking the zeroes of the equation,
x ² - 10x + 24 = 0
If the values of x are a and b, the second term of the equation is the negative of the sum of a and b. The third term is their product.
24 = ab , b = 24 / a
- 10 = - (a + b) = -(a + 24/a) ; a = 6 ; b = 4
The values of x are 4 and 6. Thus, the ordered pairs are (4, 0) and (6, 0).
Step-by-step explanation:
- The random variable (x) here would be a randomly selected student from the college that is left-handed.
- The population parameter would be 11% of America's total population. The total population as of 2019 is believed to be 328.2 million, and 11% of that figure is about 36.1 million (thirty-six million one hundred thousand).
- Hypotheses: Remember, the <u>null hypothesis</u> usually reflects the held view of the researcher, and since we are told the college wants to know if the data provide enough evidence to show that students at this college have a different percentage of left-handers than the general American population. It could read;<em> There is a statistically significant difference in the percentage of left-handers in the college than the American population. </em>While the <u>alternate hypothesis</u> could read; <em>There is </em><u><em>no</em></u><em> statistically significant difference in the percentage of left-handers in the college than the American population.</em>
- The Type I error implies rejecting the null hypothesis when it is actually true. That is: <u>Rejecting that the % of all students from that college that are left-handed is 11 % when the % is really 11 %.</u>
- The Type II error implies accepting the null hypothesis when it is actually false. That is: <u>Failing to reject that the % of all students from that college that are left-handed is 11 % when the % is actually different.</u>
Answer:
5
Step-by-step explanation:
if your subtracting a negative number, you just add it.
