Answer:
its actually a geometric because there is exponential growth. if it was arithmetic there would be a linear line as the quantities would be proportional (growing at a particular rate/at equal intervals) and if it was arithmetic it wouldn't curve
Answer:
The given equation 3x − 7 = 4 + 6 + 4x has one solution.
Step-by-step explanation:
Given : Equation 3x − 7 = 4 + 6 + 4x
We have to find the number of solutions of the given equation.
Consider the given equation 3x − 7 = 4 + 6 + 4x
Simplify, we have,
3x − 7 = 10 + 4x
Now subtract 3x both side, we hvae,
-7 = 10 + 4x - 3x
Simplify, we have,
- 7 = 10 + x
Subtract 10 both side, we have,
-7 - 10 = x
x = - 17
Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.
Answer:
PE almost equals to 153.4ft
BE almost equals to 173.9
Step-by-step explanation:
We need to the property of similar triangles,using the ratio between them to solve.
we can finnd that GR=325+225=550（Parallelogram)
so PE/375=BP/GR=9/22 so PE=(375*9)/22=153.4
BE/425=BP/GR=9/22 so BE=（425*9)/22=173.9
They are not exact numbers just near to the right answer.
Answer:
The percentage of the distribution is less than 75 is 97.72%.
Step-by-step explanation:
Given,
Mean of the distribution,
Standard deviation,
Thus, the z-score of the score 75,
With the help of z-score table,
Hence, the percentage of the distribution is less than 75 is 97.72%.
Answer:
Step-by-step explanation:
From the information given,
Mean, μ = (10.31 + 17.22 + 26.62 + 22.84)/4 = 19.2475
Standard deviation, σ = √summation(x - mean)/n
Summation(x - mean) = (10.31 - 19.2475)^2+ (17.22 - 19.2475)^2 + (26.62 - 19.2475)^2 + (22.84 - 19.2475)^2 = 151.249475
σ = √(151.249475/4)
σ = 6.15
number of sample, n = 4
The z score for 98% confidence interval is 2.33
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
19.2475 ± 2.33 × 6.15/√4
= 19.2475 ± 2.33 × 3.075
= 19.2475 ± 7.16
The lower end of the confidence interval is 19.2475 - 7.16 = 12.09
The upper end of the confidence interval is 19.2475 + 7.16 = 26.41
