Answer:

sqrt(2x/a) = t

Step-by-step explanation:

X = 1/2at^2

Multiply by 2 on each side

2x = 2*1/2at^2

2x =at^2

Divide by a

2x/a=a/a t^2

2x/a =t^2

Take the square root of each side

sqrt(2x/a) =sqrt(t^2)

sqrt(2x/a) = t

Solve for P if

bogdanovich [222]

Put each variable's value in parentheses:

P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.

The mixed number answer is 11 4/5

g Students conducted a survey and found out that 36% of their peers on campus had tattoos but only 4% of their peers were smoker

IgorC [24]

Answer:

D) No, because either np or n(1−p) are less than 15.

Step-by-step explanation:

Percentage of students who had tattoos = 36%

Percentage of students who were smokers = 4%

Sample size = n = 100

The condition to use the Normal distribution as an approximation to construct the confidence interval for population proportion is:

Both np and n(1-p) must be equal to or greater than 15.

Since, we are interested in smokers only, so p = 4% = 0.04

np = 100 x 0.04 = 4

n (1 - p) = 100 x 0.96 = 96

Since, np < 15, we cannot use the Normal distribution as an approximation here.

Therefore, the correct answer is:

No, because either np or n(1−p) are less than 15.

How do solve arc angles?

Reil [10]

Arc angles in circles depend on whether they are major arcs or minor arcs, really. Major arc, for example, would go the longest way around the circle. Refer to the picture: Major arc: > 180 Minor arc: < 180 Semicircle: = 180
