Answer:

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

Uniform distribution from 0 to 4.8 seconds.

This means that $a = 0, b = 4.8$

61% of the time a person will wait at least how long before the wave crashes in?

This is the 100 - 61 = 39% percentile, which is x for which $P(X \leq x) = 0.39$ . So

$P(X \leq x) = \frac{x - a}{b-a}$

$0.39 = \frac{x - 0}{4.8 - 0}$

$x = 4.8*0.39$

$x = 1.872$

61% of the time a person will wait at least 1.872 seconds before the wave crashes in.

Jayden wants to lay sod on his front yard and on half of his back yard. His front yard has a length of 50 feet and a width of 70

lana [24]

The first thing we must do for this case is to calculate the area of both yards.

We have then:

front yard:

A1 = (50) * (80)

A1 = 4000 feet ^ 2

Back yard:

A2 = (10) * (30)

A2 = 300 feet ^ 2

"Jayden wants to lay sod on his front yard and on half of his back yard"

Then, the total amount will be:

A = A1 + (1/2) A2

Substituting:

A = 4000 + (1/2) (300)

A = 4000 + 150

A = 4150 feet ^ 2

Answer:

jayden needs to purchase 4150 square feet of sodd

Shay created the table below to graph the equation r-3-sin theta (rounded to the hundredths place). Analyze the table. Did Shay

monitta

Answer:

B is false

Step-by-step explanation:

Let's check Shay's table:

if $\theta=0,$ then $r=3-\sin 0=3-0=3$ (true);
if $\theta =\dfrac{\pi}{6},$ then $r=3-\sin \dfrac{\pi}{6}=3-\dfrac{1}{2}=2.5$ (true);
if $\theta = \dfrac{\pi}{4},$ then $r=3-\sin \dfrac{\pi}{4}=3-\dfrac{\sqrt{2}}{2}\approx2.29$ (true);
if $\theta=\dfrac{\pi}{3},$ then $r=3-\sin \dfrac{\pi}{3}=3-\dfrac{\sqrt{3}}{2}\approx 2.13$ (false);
if $\theta =\dfrac{\pi}{2},$ then $r=3-\sin \dfrac{\pi}{2}=3-1=2$ (true).

HELP Trigonometry: Find the area of each shape using the given information

rjkz [21]

Given:

The vertical height of the trapezoid = 2.9 m

The bases of the trapezoid are 2.3 m and 9.3 m.

To find:

The area of the given trapezoid.

Solution:

The area of a trapezoid is:

$A=\dfrac{1}{2}(a+b)h$

Where, a, b are bases or length of parallel sides and h is the vertical height of the trapezoid.

Putting $a=2.3,\ b=9.3,\ h=2.9$ in the above formula, we get

$A=\dfrac{1}{2}(2.3+9.3)(2.9)$

$A=\dfrac{1}{2}(11.6)(2.9)$

$A=16.82$

Therefore, the area of the given trapezoid is 16.82 square m.
