18. P(x then y) = 1/11
19. P(both y) = 5/22
To find the probability of these compound events, we have to multiply the probability of each individual event. Remember, on the second trial, there are only 11 options.
18. 2/12 x 6/11 = 1/11
19. 6/12 x 5/11 = 5/22
<span>If each shirt costs $10 within the purchase of 1 to 75 shirts, the function will be: 10x (with x being the number of shirts, from 1 to 75). If each shirt costs $7.50 within the purchase of 76 to 150 shirts, the function will be: 7.5x (with x being between 76 and 150). Finally, if each shirt costs $6 within the purchase of 150 or more shirts, the function will be: 6x (with x being any number from 150 up). </span>
Answer:
94.5
Step-by-step explanation:
Use the trapezoid area formula:
[(a+b)/2]×h
a and b represent the bases. h is the height
both bases are 17.5 and 9.5. So plug them in.
17.5 plus 9.5 is 27.
27 divided by 2 is 13.5
Now, multiply 13.5 by the height.
13.5 times 7 is <u>94.5</u>
Answer:
$75.65
Step-by-step explanation:
$79.78 is discounted 12%. 12% of 79.78 is 9.57
79.78 - 9.57 = 70.21
Tax of 7.75% = 0.0775 x 70.21 = 5.44
70.21 + 5.44 = 75.65
Answer:
Infinitely many solutions
Step-by-step explanation:
the 5x's cancel and -15 + 6 = -9 so -9 equals -9. No matter what value you input for x, the answer is equal.
