F(x)=2x+3. easy as that, just replace y with f(x)
Answer:
x = 7
Step-by-step explanation:
Let x be the number
x+16 = 23
Subtract 16 from each side
x+16-16 =23-16
x = 7
Answer:
x=18
y=27
explanation: 4 times 3 is 12
Answer:
4
Step-by-step explanation:
All you need to do is plug in each value for x & then solve the equation to see if it equals 7. When a number, like 2, is next to an x you multiply the two of them. So when you substitute a number for x, you multiply it by the 2.
2(3)-1= 5
2(4)-1= 7
2(5)-1=9
Due to the higher z-score, the correct option regarding the highest relative score is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
<h3>What is the z-score formula?</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
The z-score measures how many standard deviations the measure is above or below the mean, hence the higher the z-score, the higher the score X is relative to other scores.
The respective z-scores for this problem are given by:
- (1136 - 1080)/67.8 = 0.83.
- (4730 - 3960)/555.5 = 1.39.
Hence the correct option is:
A score of 4730 on a test with a mean of 3960 and a standard deviation of 555.5.
