Add them all up:

15 + 4 1/2 + 6 3/4 = 26 1/4 in.

2 ft equals 24 in.

2 1/2 ft = 30 in.

Yes, it is a valid claim.

A concrete beam may fail either by shear (S) or flexure (F). Suppose that three failed beams are randomly selected and the type

Firdavs [7]

Answer:

$\begin{array}{cc}{Outcome} & {X's} & {FFF} & {0} & {SFF} & {1} & {FSF} & {1} & {FFS} & {1} & {FSS} & {2}& {SFS} & {2}& {SSF} & {2}& {SSS} & {3} \ \end{array}$

Step-by-step explanation:

Given

$S_S = \{FFF, SFF, FSF, FFS, FSS, SFS, SSF, SSS\}$

$X \to$ Number of beams failed by shear

Required

List each outcome and the value of X

To do this, we simply count the occurrence of S in each outcome.

This is tabulated as follows:

$\begin{array}{cc}{Outcome} & {X's} & {FFF} & {0} & {SFF} & {1} & {FSF} & {1} & {FFS} & {1} & {FSS} & {2}& {SFS} & {2}& {SSF} & {2}& {SSS} & {3} \ \end{array}$

The function h(t) = -4t^2 + 20t represents the height (in feet) of an athlete t seconds after pole vaulting. after how many seco

goldfiish [28.3K]

Answer:

2.5 seconds.

Step-by-step explanation:

h(t) = -4t^2 + 20t

= -4(t^2 - 5t)

Convert to vertex form by completing the square:

h(t) = -4[(t - 2.5t)^2 - 6.25]

= -4(t - 2.5)^2 + 25 <--------- vertex form

So the vertex is at the point (2.5, 25).

So the athlete reaches the maximum height ( of 25 feet), after 2.5 seconds.

Each Americana chicken lays 2 eggs per day and each Delaware chicken lays 1 egg per day.

marissa [1.9K]

Answer:

$30

Step-by-step explanation:

-One week has 7 days, so the total number of eggs laid by both chickens:

$Americana=2\times 7=14\\\\Delaware=1\times 7=7\\\\t=21\ eggs$

-One doze is equivalent to 12 items. There's only one full dozen unit in 21 pieces.

$Amount =12\times 2.5\\\\=30$

Hence, she makes $30 in week one.
