1/3 + 1/3 + 1/3 = 1 because your adding 1 of a third three times.

Since the denominator is the same, we just add the numerators
so
1/3 + 1/3 + 1/3
3/3
This is also equal to 2/2 or 1/1 or just simply 1.

Hope this helps!

13°. The value of theta using right triangle Trigonometry is 13°.

The reasons for the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are: sine (sin), cosine (cos) and tangent (tan). These are defined for the acute angle θ as follows:

Sin θ = opossite leg/hypotenuse

Cos θ = adjacent leg/hypotenuse

Tan θ = opossite leg/adjacent leg

The easiest way to solve this proble is using the reason sin θ = opossite leg/hypotenuse, where opossite leg = 11, and hypotenuse = 58.

sin θ = 11/48

θ = sin⁻¹ (11/48)

θ = 13.25°

Round to the nearest degree θ = 13°

Answer:

x>-2 and x<1

Step-by-step explanation:

$-6$

Now dividing by 4:

$-2$

So, x is the value between -2 and 1, i.e. x has to be greater than -2 and smaller than 1

Cindy works at Jurassic Park and has been tasked to design a container in the shape of a rectangular prism for the incoming baby

svetoff [14.1K]

The amount Cindy should increase in each dimension of the scaled model is 12 m.

<h3>What is a rectangular prism?</h3>

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have:

The scaled model of the container has dimensions 2m by 4m by 6m.

Volume of the scaled model = 2×4×6 = 48 cubic m

Let x be the amount by which each dimension is increased.

(2 + x)(4 + x)(6 + x) = 84(48)

$\rm 48+44x+12x^2+x^3=4032$

$\rm x^3+12x^2+44x-3984=0$

$\rm x-12=0\quad \mathrm{or}\quad \:x^2+24x+332=0$

The quadratic equation has no real solution so,

x = 12 m

Thus, the amount Cindy should increase in each dimension of the scaled model is 12 m.

What is the probability that the web site has between 3 million and 4 million visitors in a single day? If needed, round your an

faust18 [17]

Answer:

0.2196

Step-by-step explanation:

Given that

Mean = 4.56 million visitors per day

Standard deviation = 820,000 visitors per day

According to the given situation the calculation of probability is shown below:-

Here we will find the value of P (3 ≤ X ≤ 4)

$P 93\leq X\leq 4)=P(X\leq 4) - P(X\leq 3)$

$\\=P(\frac{X-\mu}{\sigma}\leq \frac{4-4.56}{0.82})-P(\frac{X-\mu}{\sigma}\leq \frac{3-4.56}{0.82})$

$\\=P(Z\leq -0.683)-P(Z\leq -1.9024$

= 0.2483 - 0.0287

= 0.2196

Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196

Refer to Expression 1 and Expression 2.

TiliK225 [7]

Expression 1 is 25

6*7-3^2*9+4^3

First simplify all the exponents to get 6*7 - 9 * 9 + 64 and then multiply the two numbers to get 42 - 81 + 64 and just add = 25

For expression 2, if you put the parantheses around (5+4)*2+6-2*2-1, it'll be 19

(5+4)*2+6-2*2-1

9*2+6-2*2-1

18+6-4-1

24-5
