Answer:

UQ = 185

Step-by-step explanation:

the median separates the data set into the lower quartile and upper quartile

The median of this data set is 151

The lower quartile is the median of the lowest five values, or 132

The upper quartile is the median of the highest five values, or 185

Answer:

4 students

Step-by-step explanation:

The total number of students is given by:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N$

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N\\51+80+70-15-20-13 + |A\cap B \cap C| = 157\\ |A\cap B \cap C| =4$

4 students in Group A have taken all three classes.

*The number of students that have taken two classes has be subtracted so those students do not get counted twice

Answer:

The 95% confidence interval $81.852 < \mu < 280.098$

Step-by-step explanation:

From the question we are told that

The sample mean is $\= x = 180.975$

The standard deviation is $\sigma = 143.042$

The sample size is n = 8

Given that the confidence level is 95% then the level of significance is

$\alpha =( 100- 95) \%$

=> $\alpha =0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{ 143.042 }{\sqrt{8} }$

=> $E = 99.123$

Generally 95% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $180.975 -99.123 < p < 180.975 +99.123$

=> $81.852 < \mu < 280.098$

Answer:

ΔLMN ~ ΔLFG; scale factor 7/3

Step-by-step explanation:

The ratios of side lengths, shortest to longest are ...

FG : GL : LF = 24 : 36 : 42 = 4 : 6 : 7 (reduced)

MN : NL : LM = 56 : 84 : 98 = 4 : 6 : 7 (reduced)

The side ratios are the same, so ΔLMN ~ ΔLFG. The scale factor is ...

MN/FG = 56/24 = 7/3
