A<b<c
b is the square root of 20
if we square everybody
a²<b²<c²
if we say that b²=20 then
a²<20<c²
find a and c
2^2=4
3^2=9
4^2=16
5^2=25
16<20<25
sqrt both sides
4<√20<5
somewhere between 4 and 5
closer to 16 than 25
A
The slope should be -1 and the y intercept is 3
Answer:
Juanita is saving $0.10 a pound.
Step-by-step explanation:
Find the new price that the salesman offered her, by dividing the total price by the number of pounds of stones:
21.25 / 12.5
= 1.70
This means the new price is $1.70 a pound
Then, find the difference between the new price and the original:
1.80 - 1.70
= 0.10
So, Juanita is saving $0.10 a pound
16. Is 77=x
Sqrt 2x+15=13
169=2x+15
154=2x
77=x
Answer:
A. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution - false
B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution - True
Step-by-step explanation:
A. The area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution- This statement is false in the sense that it is a point that is equivalent to corresponding point of normal distribution.
B. A z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution. - This statement is true in the sense that z-score is in the normal standard distribution.
C. A z-score is an area under the normal curve - This statement is true in the sense that z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution.
D. If values are converted to standard z-scores, then procedures for working with all normal distributions are the same as those for the standard normal distribution - This statement is absolutely true
