The graph below shows the cost, in
dollars, per notebook at the school store.
Which equation represents the total cost, T, per n notebooks?
Answers
Answer:
t = 2.4n
Step-by-step explanation:
y = mx + c
t = mn + c
c = y-intercept (where the graph line crosses the cost line)
c = 0
mx/mn= gradient ( rise/run, up/across)
mn= 12/5 ( you could have picked any point in the graph )
mn= 2.4
the m is unnecessary now so we discard it
t = 2.4n + 0

help pls with these two about surface area
Answers
Answer:
6) 152.6
7) 348.4
Step-by-step explanation:
For question number 6, calculate the surface area of the two triangles first. And then, calculate each of the surface area for the rectangles. Finally, total up the area of the two triangles and the rectangles.
[tex](6.6 \times 9) + (4 \times 9) + (5.2 \times 9) \times (\frac{1}{2} \times 5.2 \times 4) = 152.6[/tex]
For question number 7, given that the area of a triangle is 28.4. Hence calculate the area of the three rectangles. Lastly, total up the area of two triangles and three rectangles.
[tex]28.4 + 28.4 + 3(12 \times 8.1) = 348.4[/tex]

5. A population has a normal distribution with a mean of 50 and a standard deviation of
10. If a random sample of size 9 is taken from the population, then what is the
probability that this sample mean will be between 48 and 54?
a. 0.060
b. 0.228
c. 0.385
d. 0.399
e. 0.611
Answers
Using the normal distribution and the central limit theorem, it is found that the probability is given by:
e. 0.611
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem, the parameters are given as follows:
[tex]\mu = 50, \sigma = 10, n = 9, s = \frac{10}{\sqrt{9}} = 3.3333[/tex]
The probability that this sample mean will be between 48 and 54 is the p-value of Z when X = 54 subtracted by the p-value of Z when X = 48, hence:
X = 54:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{54 - 50}{3.3333}[/tex]
Z = 1.2
Z = 1.2 has a p-value of 0.885.
X = 48:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{48 - 50}{3.3333}[/tex]
Z = -0.6
Z = -0.6 has a p-value of 0.274.
0.885 - 0.274 = 0.611, hence option e is correct.
