440 in^2 is the surface area
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:
<h3>#1</h3>
<u>The system of equations:</u>
- 2x + 7y = -11
- 3x + 5y = -22
Solve by elimination.
<u>Triple the first equation, double the second one, subtract the second from the first and solve for y:</u>
- 3(2x + 7y) - 2(3x + 5y) = 3(-11) - 2(-22)
- 6x + 21y - 6x - 10y = -33 + 44
- 11y = 11
- y = 1
<u>Find x:</u>
- 2x + 7*1 = -11
- 2x = -11 - 7
- 2x = -18
- x = -9
<u>The solution is:</u>
<h3>#2</h3>
<u>Simplifying in steps:</u>
- 8u - 29 > -3(3 - 4u)
- 8u - 29 > - 9 + 12u
- 12u - 8u < -29 + 9
- 4u < -20
- u < -5
for volume of prism you do area of cross section * height
area = 36
height = 15
=36*15
=540cm ^3
It depends. Did you write it correctly?There is two names Deja and Daniel. If its two people going into the fair and the admission fair is $4 each , then for both the admission would be $8. If that is the case then subtract 8 from $25 and you are left with $17. We will asume Deja, as well will get on the rides not Just Daniel, but the money is for both. So I just kept multiplying a number which represents the rides by $1.25. For example, 1.25×13= $16.25, 1.25×14=17.50 it is too high, 1.25×12=$15, so if both get on then it has to be even the rides, So dived the rides which the greatest was 12 , then you will be left with 6 rides each. So the greatest number daniel go on was 6. However, if you just wrote the name wrong and it is only one person we are talking about, then it is still the same process just instead we will subtract $4 from $25, and Daniel is left with $21 for the rides. Just multiply 1.25 by a number until you get close but not past the amount of $21. example,
1.25×16=$20, 1.25×17=$21.25. The answer is 16. The greatest number Daniel rides is 16.
