Answer:

70 + 95 = 5(14 + 19)

gcf = 5

Step-by-step explanation:

70+95

70=2*5*7

95=5*19

70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)

5*33=165 and 70+95=165 Hope this helps! Please give me brainly!

Tema [17]

Answer:

The answer to your question is 191

Step-by-step explanation:

Data

Total number of students = 464

Students in a band = 89

Students in sports = 215

Students in both activities = 31

Students do not practice any activity = ?

Process

1.- Subtract 31 from the students in a band and students in a sport

89 - 31 = 58

215 - 31 = 184

2.- Add the previous results anfd the number of students that practice both activities

58 + 184 + 31 = 273

3.- Subtract 273 from the total number of students

464 - 273 = 191

4.- Conclusion

191 students are not involved in any activity.

Tomtit [17]

Answer: $(10.1989,\ 11.0011)$

Step-by-step explanation:

Given : Sample size : n=69

Sample mean : $\overline{x}=10.6$

Standard deviation : $s=1.7$

Significance level : $\alpha:1-0.95=0.05$

Then , Critical value : $z_{\alpha/2}=1.96$

The formula to confidence interval is given by : -

$\overline{x}\pm z_{\alpha/2}\dfrac{s}{\sqrt{n}}\\\\\Rightarrow\ 10.6\pm (1.96)\dfrac{1.7}{\sqrt{69}}\\\\\approx10.6\pm0.4011=(10.6-0.4011,10.6+0.4011)=(10.1989,\ 11.0011)$

Hence, the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= $(10.1989,\ 11.0011)$
