It is normal based on the Central Limit Theorem. According to the theorem, an appropriately big sample (infinite) size from a population with a limited level of variance, the average of all samples from the same populace will be roughly equivalent to the mean of the population.

Kate has a kite with the dimensions shown below. What is the value of X?
sergij07 [2.7K]
Hey there! :D

We will use the properties of similar triangles to figure this out. 

We will use two triangles inside the kite, with sides with the value of "x". 

Smaller triangle:

Smaller side= 11

Bottom side= x

Bigger triangle:

Smaller side= x

Bottom side= 25

\frac{11}{x} = \frac{x}{25}

Cross multiply. 

25*11= 275

x*x= x^{2}

Find the square root. 

√275= 16.583.... 

Or 5√11. 

I hope this helps!

The question has to do with scientific notation

<h3>What is scientific notation?</h3>

Scientific notation is the expression of a number in the form a ×  10ⁿ where 1 ≤ a ≤ 10 and n is an integer.

<h3>How to simplify the expression?</h3>

Now to simplify the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) both number have to have the same exponent to the power of 10.

So, re-writing, we have

(9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = (9 × 10⁻¹³) - (6.3 × 10⁻¹³ × 10⁻²)

= (9 × 10⁻¹³) - (6.3 × 10⁻² × 10⁻¹³ )

= (9 × 10⁻¹³) - (0.063 × 10⁻¹³ )

= (9 - 0.063) × 10⁻¹³ )

= 8.937 × 10⁻¹³

So, simplifying the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = 8.937 × 10⁻¹³

Scarlet is leaning a 12 foot ladder. When you lean a 12 foot ladder, it is s slanted so we will make 12 our slanted side or hypotenuse. It makes a 80 degree angle after contact with the ground so it will be on the lowest angle on the right. We are asked to find the vertical side or how high up the ground is. We are asked to a angle that is opposite of the given angle which is x .. And we are also given the hypotenuse. We are going to use sin using our SOHCAHTOA

\sin(theta)  =  \frac{opposite}{hypotunese}

Where there is our given angle.

Let plug it in

\sin(80)  =  \frac{x}{12}

Multiply 12 by both sides and we get

\sin(80)  \times 12 = x

Which about 11.8 if rounded to nearest tenth or 11.82 if rounded to nearest hundredth.

IF ROUNDED TO NEAREST TENTH, 11.8

IF ROUNDED TO NEAREST HUNDRETH, 11.82
