Answer:
0.1
Step-by-step explanation:
Solving using empirical rule formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Hence, the lower bound 95% =
μ - 2σ
Mean = 0.2
Standard deviation of 0.05
= μ - 2σ
= 0.2 - 2(0.05)
= 0.2 - 0.1
= 0.1
The lower bound is 0.1
Answer:
0.75x = 23.97
Step-by-step explanation:
The total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75.
Answer:
Eldest: $298500
Middle: $165250
Youngest: $149250
Explanation:
We can show the siblings like this:
e=2y (eldest)
m=16000+y (middle)
To find the value of y, or the youngest sibling, we use an equation.
2y+16000+y+y=613000
Simplify:
4y+16000=613000
Subtract 16000 on both sides:
4y=597000
Divide both sides by 4:
y=149250
The youngest received $149250.
Knowing this, we can plug in the numbers into the original formulas:
e=2(149250)=298500 ...or $298500
m=16000+149250=165250 ...or $165250
y=149250 ...or $149250
Add all those numbers up, and you reach $613000.
Answer:
The slope is : -8/1
Step-by-step explanation:
2-y=8x
We need to get “y” by itself , so subtract “ 2 “ from both sides
-y=8x-2
Then we still have to get “ y” by itself , but it’s Negative “y” now! Divide both sides by “ negative one “ (-y is just like -1y).
-y/-1 = 8x/-1 (-2/-1)
* I put the -2/-1 on () just to organize it *
y = -8x +2
2: y-intercept
-8: slope
[ y = -8x + 2 ] and this called the y-intercept form .✨
