Amount of tax would be: 6.95*20/100 = 139/100 = 1.39
So, the amount of 20% tax on $6.95 lunch would be $1.39
Whatever your choices are, just substitute the x and y values to the equations. If they satisfy the inequality, then they are the solutions. For example, point (7, 1) satisfies the inequalities.
y > -2x
1 > -2(7)
1 > -14 (true)
<span>3y < x – 2
3(1) < 7 - 2
3 < 5 (true)

Answer:
3 + 5i
Step-by-step explanation:
Given
- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis

= 3 + 5i
Answer: C- Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.
<u><em>Note: I'm not sure this is correct o_O

I used a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:
<em>tInterval 9.68,1.23,125,0.99</em>
It resulted in 9.68 ± 0.287805.
Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.
A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.
