You can't reach the end of the rainbow because a rainbow is kind of like an optical illusion. A rainbow is formed because raindrops act like little prisms. So no matter how you move, the rainbow will always be the same distance away from you. That's why you can never reach the end of the rainbow.

He needs to square each deviation in the numerator.

==========================================================

Explanation:

The sample standard deviation involves these steps

The step 3 highlighted in bold is where Toby made an error. He subtracted xbar from each person correctly, but forgot to square those deviations. The squaring is done to ensure we don't have any negative deviations.

This is what his work should look like when calculating the sample standard deviation

Answer:

396 males

Step-by-step explanation:

First, let's find the percentage of males who took part in the survey.

Now, let's find 55% of 720.

Step 1: Multiply 55 by 720

Step 2: Divide 39,600 by 100.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

The number of males took part in the survey is 396.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, 720 students took part in the survey.

Only 45% were female.

So, the number of females = 45% of 720

= 45/100 ×720

= 0.45×720

= 324

So, number of males = 720-324

= 396

Therefore, the number of males took part in the survey is 396.

Answer:

The answer is 1.25 km = 1,250

                       1.7 cm =17 mm

                       345 m = 0.345 km K12 test.

Step-by-step explanation:

The answer is 1.25 km = 1,250

                      1.7 cm =17 mm

                      345 m = 0.345 km K12 test.

The value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The 4-column 2 rows table which shows the number of heads and probability of that is shown below.                    

Heads                       0                1              2

Probability.                a               b             c

When a coin is flipped two times, then we get the four outcomes. The sample space for flipping a coin twice is,

[tex]{HH, HT,TH, TT}[/tex]

Here, the H represent the head and T represent the tail. Only one time in four events there is no head appear. In this sample space, the probability of 0 heads both the time is,

[tex]P_0=\dfrac{1}{4}=0.25[/tex]

The 1 head appears twice in the sample space (HT, TH). Thus, the probability of 1 heads both the time is,

[tex]P_1=\dfrac{2}{4}=0.50[/tex]

On both flip, head appears a single time in the sample space (HH). Thus, the probability of 2 heads both the time is,

[tex]P_2=\dfrac{1}{4}=0.25[/tex]

The new table for these values is attached below.

Hence, the value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.

The energy that it takes to melt 2 kg of ice is; (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ

We are given;

Mass of ice; m = 2 kg

Now, from tables showing constants for ice, we see that;

Molar heat of fusion for ice; Δ_fus.H = 6.03 kJ/mol at 0°C.

Molar mass of Ice which is water is; 18.02 g/mol

Formula to get the energy is;

E = (m/M) * Δ_fus.H

E = (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ

........

The expression that is equivalent to [tex]\sqrt{\frac{2x^{5} }{18} }[/tex] is [tex]x^{2} \frac{\sqrt{x} }{3}[/tex].

The given expression is [tex]\sqrt{\frac{2x^{5} }{18} }[/tex].

We can write the above expression as [tex]\sqrt{\frac{2.x^{2} .x^{2} .x}{2*9} }[/tex]

The square root of [tex]x^{2}[/tex] i.e. [tex]\sqrt{x^{2} } =x[/tex] and same for [tex]\sqrt{9} =3[/tex].

So, we can write the expression [tex]\sqrt{\frac{2.x^{2} .x^{2} .x}{2*9} }[/tex] as [tex]\frac{x.x\sqrt{x} }{3}[/tex].

So, [tex]\frac{x.x\sqrt{x} }{3}= x^{2} \frac{\sqrt{x} }{3}[/tex].

Therefore, the expression that is equivalent to [tex]\sqrt{\frac{2x^{5} }{18} }[/tex] is [tex]x^{2} \frac{\sqrt{x} }{3}[/tex].

Step-by-step explanation:

The measure of two supplementary angles =  15:21

The angles are  15x , 21x

15x + 21x = 180       {Supplementary}
