Students in a fifth-grade class were given an exam. During the next 2 years, the same students were retested several times. The average score was given by the model f ( t ) = 92 − 4 log 10 ⁡ ( t + 1 ) , 0 ≤ t ≤ 24 where t is the time in months.

Answers

Using the logarithmic function, it is found that:

a) The initial score is of 92.

b) After 6 months, the score is of 88.6.

c) After 18 months, the score is of 86.9.

The average score after t months is modeled by:

[tex]f(t) = 92 - 4\log{(t + 1)}[/tex]

Item a:

The initial score is of f(0), hence:

[tex]f(0) = 92 - 4\log{1} = 92 - 0 = 92[/tex]

The initial score is of 92.

Item b:

After 6 months, the score is of f(6), hence:

[tex]f(6) = 92 - 4\log{7} = 88.6[/tex]

After 6 months, the score is of 88.6.

Item c:

After 18 months, the score is of f(18), hence:

[tex]f(6) = 92 - 4\log{19} = 86.9[/tex]

After 18 months, the score is of 86.9.

More students are in chorus

Given

Percentage of students in Chorus.

Fraction of students in band

To find

Which has more students.

Let's start.

We need to find the Percentage of students in band.

[tex]\sf \longmapsto \: \dfrac{5}{9} \times 100[/tex]

[tex]\sf \longmapsto \: \dfrac{5}{9} \times \dfrac{100}{1} [/tex]

What is 23=5-2/3m ??????

Answers

Answer:

Step-by-step explanation:

if it's

23 = 5 - (2/3)m

18 = (-2/3)m

m = 18(-3/2)

m = -27

if it's

23 = 5 - 2/(3m)

18 = -2/(3m)

18(3m) = -2

54m = - 2

m = -2/54

m = - 1/27

Answers

Using a confidence level of 95%, the margin of error for the estimate of the mean number of television hours watched will be 1.129

The approximate margin of error can be calculated using the relation :

Margin of Error = [tex] Z_{\frac{α}{2}} \frac{σ}{\sqrt{n}} [/tex]

Sample size, n = 25 Standard deviation, = 2.88Confidence level = 95%

[tex] Z_{\frac{α}{2}} = 1.96 [/tex]

Margin of Error = [tex] 1.96 \frac{2.88}{\sqrt{25}} [/tex]

Margin of Error = [tex] 1.96 \frac{2.88}{5} [/tex]

Margin of Error = [tex] 1.96 \times 0.576 [/tex]

Margin of Error = [tex] 1.129 [/tex]

Therefore, the margin of error for the estimate of the mean number of television hours watched is 1.129.
