What’s the z score ?

Mathematics
1 answer:
castortr0y [4]4 years ago
7 0
The value of the z-score tells you how many standard deviations you are away from the mean. ... A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average

Answer:

x = 3^{11}

You are designing the garden of your dream and you are going to start with a blank canvas. That means killing everything before
Aleks [24]

Answer:

2.5 bottles or 3 bottles

Step-by-step explanation:

Given that :

Dimension of lot :

22.5 yds by 20.4 yds

Area of lot = 22.5 * 20.4 = 459 yd²

Volume per bottle of herbicide = 12 fl oz

1.1 fl oz combined with water treats an area of 155 ft²

Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90

1 yard² = 9 feet²

459 yard² = (459 * 9) = 4131 feet²

Number of 151 feet² that can be obtained from 4131 feet²

4131 feet² / 155 ft²

= 27.3576 times

= 27.3576 / 10.909

= 2.507

This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.

#9 was the the one I need help with anyone plz help Thank You:)

Your answers are wrong. the function f(x) is like a factory. you put in something ( a number) and it will spit you out something else (a different number depending on the function). your function, f (x)= -2x+1

you can put anything in that function. let say k.
f(x=k) = -2k+1. you just replace the x with k.
in this particular problem they way f(-2) ,f(0), f(1) and f(2).
here are the results
f(x=-2) = f(-2) = -2×(-2)+1 =5
f(x=0) = f(0) = -2×(0)+1 =1
f(x=1) = f(1) = -2×(1)+1 =-1
f(x=2) = f(2) = -2×(2)+1 =-3
