Goshia [24]

Answer:

$\sqrt{4}$

Step-by-step explanation:

Because

→ $\sqrt{4}$ is equal to 2

→ $\sqrt{125}$ is equal to $5\sqrt{5}$ or 11.18033989

→ $\sqrt{0.6}$ is equal to $\frac{\sqrt{15} }{5}$ or 0.7745966692

→ $\sqrt{12.35}$ is equal to 3.514256678

Randomly selected students participated in an experiment to test their ability to determine when one minute (or sixty seconds)

zalisa [80]

Answer: $(57.41,\ 62.19)$

Step-by-step explanation:

Given : Sample size : $n=40$

Sample mean : $\overline{x}=59.8\text{ seconds}$

Standard deviation : $\sigma =9.2\text{ seconds}$

Significance level : $\alpha=1-0.9=0.1$

Critical value : $z_{\alpha/2}=1.645$

Formula to find the confidence interval for population mean :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=59.8\pm(1.645)\dfrac{9.2}{\sqrt{40}}\\\\\approx59.8\pm2.39\\\\=(59.8-2.39,\ 59.8+2.39)\\\\=(57.41,\ 62.19)$

Hence, a 90% confidence interval estimate of the population mean of all students = $(57.41,\ 62.19)$

Write the equation that satisfies the given conditions. The line passes through the two points (3, -1) and (-2, 5). Choices A. 5

rodikova [14]

(3,-1)(-2,5)
slope = (5 - (-1) / (-2 - 3) = -6/5

y = mx + b
slope(m) = -6/5
(3,-1)...x = 3 and y = -1
sub and find b, the y int
-1 = -6/5(3) + b
-1 = -18/5 + b
-1 + 18/5 = b
-5/5 + 18/5 = b
13/5 = b

so ur equation is : y = -6/5x + 13/5
