The interval of 95% confidence, for normally distributed variables, is average +/- 2 * standard deviation:
(-2*standard deviation + average , average + 2*standard deviation)
(-2*18 + 62.5 , 2*18 + 62.5) = (-36 + 62.5 , 36 + 62.5) = (26.5 , 98.5)
Answer: option D)
Answer:
I have tried but I can't sorry friend
Answer:
x+2/2(2x+1)
Step-by-step explanation:
Tamlin has x male action figures and x + 2 female action figures, so a total of x + x + 2, or 2x + 2 action figures. The probability of picking two female action figures without replacement is equal to the product of the probability of
-picking 1 female action figure from the total number and
-picking 1 female action figure after 1 has been removed.
The probability of picking 1 female action figure from the total is equal to the total number of female action figures divided by the total number of action figures.
The probability of picking 1 female action figure after 1 has been removed is equal to the total number of female action figures minus 1 divided by the total number of action figures minus 1.
Multiply these two expressions and simplify.
It would be Y=4/3x+9 for slope intercept form
Answer:
-128
Step-by-step explanation:
When it says that x = a number, it means you just need to plug in that number for x in the equation. So in this case, we'd plug in -12 and get:
y = -200-6(-12)
Simplify. According to PEMDAS, we do multiplication first. If a number is in parentheses, you multiply it by the number in front of (to the left) of it. In this case, we multiply -6 x -12 and get:
y= -200+72
Add, and our final answer is:
y=-128
Hopefully this helped, and if I was correct, I'd appreciate it if you marked me as the Brainliest :)
