Answer: 99.7% of babies learn to walk within 3 standard deviations from the mean in a normal distribution.
Explanation: In the normal distribution given here, that breaks down to about 68.2% between 7.5 and 10.5 months, 13.6% between 6 and 7.5 months, 13.6% between 10.5 and 12 months, 2.1% between 4.5 and 6 months and 2.1% between 12 and 13.5 months.
This is applying the percentages for the Standard Deviations shown on a Gaussian Curve.
Find the intercepts and graph the following linear equations: 2x−y=0
Answer:
0=y intercept.
Explanation:
Make this into slope intercept form: y=mx+b
-y=-2x+0
y=2x-0
In this case, 2 is the slope, and 0 is the y intercept.

Tech A says that measuring alcohol content in gasoline involves using water. Tech B says that as lonv as the fuel pressure is correct, you dont have to worry about the fuel pump volume. Who is correct?
Answer:
A is is the answer it actually the right answer
Explanation:
gasoline contains water
Tech A says that measuring alcohol content in gasoline involves using water is correct As it is involved to measure the alcohol content.
What is the gasoline amount ?
Nowadays there are gas kinds to be had on the gas station for passenger vehicles: E100 (AEHC) this is the derived from easy distillation procedure and feature approximately 4.9% water content material in it and Gasoline C or E25, that's a combination of 75% Gasoline.
Just take the variety of milliliters on the separation line and subtract milliliters — which become the quantity of water we added. Take the variety you get and multiply it with the aid of using 10, and this is the proportion of alcohol withinside the gasoline.

For the function f (x) = (-6x - 2)^2 , what is f (-7)? a. -40 b. 40 c. 80 d. 1600 e. 1936
Answer:
1600
Explanation:
If the equation starts with f(-7), then we have to replace the x in the equation to -7.
f(-7) = (-6 (-7) - 2)^2
Next, we multiply -6 and -7 to get a positive 42, since a negative number multiplied by a negative number is a positive number. Then, we subtract 2 from 42 to get 40. Finally, we square 40 by 2 (40 * 40) to get our answer: 1600!

Carlos is a senior and is looking forward to taking his girlfriend, Rachel, to the prom this
spring, but he needs to save his money to rent a tux. Carlos works part-time and brings
home $150 each week. He bought a used car last month and his payment is $200 per
month. His parents cover his insurance, but he must cover his gas ($15 a week) to and
from work and school. Carlos also has a cellphone, which costs $85 per month. He
hopes to attend college this fall and plans to live at home, but he needs to save up to
pay for his tuition and books. In order to afford the fall semester, he needs to
contribute $200 each month to his college savings account. Looking at his budget, how
much does Carlos have left over each month to put towards his tux rental?
O $75
O $55
$25
O $100
The correct answer is B. $55
Explanation:
To solve this mathematical problem you need to find the total budget of Carlos and then deduct all his monthly expenses, which would be equivalent to the money left for his tux.
1. To begin, we know each week Carlos earns $150, this means the total each month is $600 ($150 x 4 weeks each month = $600)
2. The expenses of Carlos include $200 for his car each month, $15 of gas each week or $60 each month ($15 x 4 = 60), $85 for his cell phone each month, and $200 for his tuition. This means, his total expenses are $545 ($200 + $60 + $85 + $200 = $545)
3. This means the money left for his tux is $55 as $600 (total of money) - $545 (total of expenses) = $55 (money left)
using 2,6 and -2,0 what is the slope
Answer:
[tex] \frac{3}{2} [/tex]Explanation:
Let the points be A and B
A ( 2 , 6 ) ----> (x1 , y1 )
B ( -2 , 0 ) ----> (x2 , y2)
Now,
finding the slope:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{0 - 6}{ - 2 - 2} [/tex]
[tex] = \frac{ - 6}{ - 4} [/tex]
[tex] = \frac{3}{2} [/tex]
Hope this helps...
