Just divide the numbers and times them
Answer:
f(x) = -x -4 or f(x) = (-x)-4
Step-by-step explanation:
Let the graph of g be a translation of 4 units down followed by a reflection in the y-axis of the graph of f(x)=x. Write a rule for g.
Transformations can be found using this general formula: f(x) = a(bx-h)+k
For this question, we want a translation down as well as a reflection.
The two values we need to use are for k, a vertical translation, and b, a reflection over the y-axis.
Since we are translating down 4 units, k = -4
Since we are reflecting across the y-axis, b = -1
So, f(x)=(-x)-4
or
f(x)= -x -4
Answer:
he would need 31 tanks
30 tanks would hold 240 fish with 6 left over
Step-by-step explanation:
246/8= 30.75
30*8 = 240
In one hour, they can make 32 bagels.
In 12 hours, they can make 384 bagels.
Answer:
1329.85≤μ≤1330.14
Step-by-step explanation:
z score for 99% confidence interval
from the z table we can find that the score for 99% confidence is 2.58
formula
z=![\frac{x-μ}{[tex]\frac{{σ}[tex]\sqrt{n}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B%CF%83%7D%5Btex%5D%5Csqrt%7Bn%7D)
}[/tex]}[/tex]
where
x-sample mean
μ-population mean
σ-population standard deviation
n-sample size
2.58=![\frac{1330-μ}{[tex]\frac{{442}[tex]\sqrt{24}](https://tex.z-dn.net/?f=%5Cfrac%7B1330-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B442%7D%5Btex%5D%5Csqrt%7B24%7D)
}[/tex]}[/tex]
1330-2.58×24÷442≤μ≤1330+2.58×24÷442
1329.85≤μ≤1330.14
