Salsk061 [2.6K]

Answer:

Each marker will be exactly <u>103</u> miles apart.

Step-by-step explanation:

It is given that Ian wants to run 412 miles and has set up 3 markers the same distance apart.

Between the start and end of run, the 3 separate markers will divide the 412-mile distance into 4 equal segments.

So each segment = 412/4 = 103 miles

Each marker will be exactly <u>103</u> miles apart.

stepladder [879]

Answer: 196

Step-by-step explanation:

As per given , we have

Population standard deviation: $\sigma=0.6\ lb$

Significance level : $\alpha: 1-0.98=0.02$

Using the z-value table , the critical z value for 98% confidence : $z_{\alpha/2}=2.33$

Margin of error : E= 01 lb

Sample size : $n=(\dfrac{z_{\alpha/2}\cdot\sigma}{E})^2$

$n=(\dfrac{(2.33)\cdot(0.6)}{0.1})^2$

Simplify , we get

$n=195.4404\approx196$

Hence, the minimum sample size required for books = 196

drek231 [11]

Answer:

PL = 9

PN = 5√5

Step-by-step explanation:

8/12 = 6/PL

8PL = 72

PL = 9

PN² = 10² + 5² = 100 + 25 = 125

PN = √125 = 5√5
