Answer:
option A: 0.2357
Step-by-step explanation:
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39)
P(X < 1.76) = 0.0126 (as per the excel output)
P(X < 2.39) = 0.7769
Hence P( X> 2.39) = 1- 0.7769 = 0.223
P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39) = 0.0126 + 0.223 = 0.2357
P( less than 1.76 or greater than 2.39) = 0.2357
Step-by-step explanation:
4x-2y = 9 ...1
2x-y = -6 ...2
if ...2 × 2
4x-2y = -12
9 is not equal to -12
She paid $100 because she bought the almonds for $77 then she received $23 back (100-77=23) (77+23=100)

The question is incomplete:
17. Tonya's mother is 1.5 times as tall as Tonya was when she was 6. How tall is Tonya's mother? Use the correct number of significant digits.
The image with the information about Tonya's height is attached.
Answer:
68 in.
Step-by-step explanation:
According to the information given, you can write the following expression:
x=1.5y
x=Tonya's mother height
y= Tony's height when she was 6
Also, you know from the table that Tonya's height when she was 6 was 45 in. and you can replace this value in the formula:
x=1.5*45
x=67.5
Because of this, the answer is that Tonya's mother height is 68 in.
