Answer:
$8.10
Step-by-step explanation:
2.70+2.70+2.70=$8.10
1. 2. 3. total
Z score = (x -mean) / standard deviation.
For this problem X = 50 cm.
Z-score = (50 - 49.2) / 1.8
Z score = 0.8 / 1.8
Z score = 0.44
Look up 0.44 on a z-score table.
0.44 = 0.6700
0.67 x 100 = 67% will be 50 cm or longer.
The answer is x=-15 and y=25
Answer:
The blue area is y is less than or equal to 5
The purple area is y is greater than or equal to x.
The green area is less than or equal to 2.
Step-by-step explanation: The solid lines indicate that y=5, y=x. and x=2 Also the shaded regions would be y<5, y>x and x<2
Sorry my keyboard doesn't have the symbols for <= less than or equal to or greater than or equal to >= so I have to spell them out.
