Answers

When finding the least common denominator you look at the denominator of the fraction which is the number below the line.

To find the least common denominator in this question you would find the common multiple of 4,5,and 3

Which ever common multiple shows up first is your answer

Multiples of 4,5, and 3 :

4 8 12 16 20 24 28 32 36 40 44 48 52 56 60

To solve this, you'll have to divide 13 and 20.
You should get, 0.65. So, the answer is 65%

13/20* (100/100)
= (13/20* 100)/ 100
= 65/100
= 65%

The final answer is 65%.

A distribution is positively skewed if which of these statements is true about the density curve that represents it?A. The left side is a mirror reflection of the right side.
B. The left tail is equal in length to the right tail.
C. The left tail is longer than the right.
D. The right tail is longer than the left.

Answers

The right answer for the question that is being asked and shown above is that: "D. The right tail is longer than the left." Positively skewed distribution is asymmetrical and points in the positive direction. So, the tail on the right is longer than that of the left.

The height of an object after it is released can be modeled by the function f(t)=-16t^2+vt+s, where t is the number of seconds after the object is released, v is the upward speed at release, and s is the starting height. If a quarterback throws a ball from his hand 6 feet in the air at a speed of 25 feet per second, how much time does his teammate have to catch the ball?about 1.45 seconds
about 1.77 seconds
about 6 seconds
about 25 seconds

Answers

Answer about 1.77 seconds.

f(t) = -16 t^2 + 25t + 6

f(t) = height.

hieght = 0 = -16t^2 + 25t + 6

Find t using the quadratic formula,

t = ( - 25 +/- √[25^2 - 4 (-16)(6)] ) / [2*(-16)]

t = [-25 +/- √ (625 + 384) ] / -32

t = [-25 +/- 31.76] / -32.

You will obtain two results one positive and one negative. Take the positive only as the other one has no physical meaning. t = 1.77 s.

B.) about 1.77 seconds
