1.) Surface Area:

Formula: A= 2(wl+hl+hw)

A= 2(2*3+4*3+4*2)
A= 2(6+12+8)
A= 2(26)
A=52.

2.) Cube Surface Area
Formula: A=6 $a^{2}$

thus, 6 $x^{2}$ square units.

The surface area of a rectangular prism is:
A = 2( (2*3) + (4*2) + (4*3) ) = 2( 6 + 8 + 12 ) = 2(26) = 52 so the answer for the first one is : 52in.^2
and for the second one u should know the surface area of a cube is:
6x ^2 so the answer is:
6x^2 square unites :)))
i hope this is helpful
have a nice day

the pathway of sams dive into the swimming pool can be represented by the equation h=-16t²+15t+12 (where t=time in seconds and h

Given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

<h3>What is a Quadratic Equation?</h3>

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

Given the data in the question

Equation of the pathway of sams dive into the swimming pool is h = -16t² + 15t + 12.
Time t = 2.0 seconds
Height h = ?

Now, to get the height after 2 seconds, we substitute 2 for t in the equation.

h = -16t² + 15t + 12.

If t = 2

h = -16(2)² + 15(2) + 12

h = -16(4) + 30 + 12

h = -64 + 30 + 12

h = -64 + 42

h = -22ft

Therefore, given the equation representing the pathway of sam's dive into the swimming pool, his height after two seconds is -22ft.

Food allergies affect an estimated 7% of children under age 5 in the US. What is the probability that in a kindergarden class of

bezimeni [28]

Answer:

Probability of atleast one of 12 student has food allergies ≈ 0.58 ( approx)

Step-by-step explanation:

Given: Probability of a children under age 5 has food allergies = 7%

= $\frac{7}{100}$

To find : Probability of atleast one of 12 student has food allergies

Probability of a chindren under age 5 does not have food allergies = $1-\frac{7}{100}$

⇒ prob = $\frac{93}{100}$

now we find Probability of atleast one of 12 student has food allergies this means we have to find prob of 1 student, 2 student, 3 student, till 12 student have allergy out of 12 student of class then add all prob.

But instead of finding all these probability we find probability of student having no allergy.i.e., 0 student then subtract it from 1(total probability)

Probability of 0 student having allergy out of 12 student = $(\frac{93}{100})^{12}$
