The required probability is given by  P(E') =4/35  .

Probability is the study of chance. It can also be defined as the ratio of the favorable outcomes to an event to the total number of outcomes of the event.

Given the total number of people in the USA = 273000000

Let E be the number of people who speak English at home.

Therefore the number of people who don't speak English at home is E'.

∴ E' = 31200000

S speak Spanish in their homes.

∴ S = 50% of 31200000 = 15600000

Now let us find the required probabilities.

We know that probability = favorable outcome ÷ total outcome

total outcome = 273000000

a) favorable outcome(E') = 31200000

P(E')=31200000/273000000

P(E') =4/35

b)favorable outcome(E) = 273000000 - 31200000 = 241800000

P(E) = 241800000/273000000

P(E)={31}/{35}

c)favorable outcome = 15600000

P(S)={15600000}/{273000000}

P(S)={2}/{35}

Therefore the required probability is given by P(E') =4/35 , [tex]P(E)=\frac{31}{35}[/tex] P(E)=31/35 and P(E)=2/35and .

The probability that the customer is at least 30 but no older than 60 is o.45, that the customer is either older than 60 or younger than 40 is 0.68 and that the customer is at least 60 is 0.22.

We have the data:

  Age                 Number of Customers

 < 20                                78

20 - 30                             58

30 - 40                             53

40 - 50                             77

50 - 60                             52

 > 60                                91

The probability that the customer is at least 30 but no older than 60 will be:

P = 182 / 409

P = 0.45

The probability that the customer is either older than 60 or younger than 40 will be:

P = 280 / 409

P = 0.68

The probability that the customer is at least 60 will be:

P = 91 / 409

P = 0.22

Therefore we get the probability that the customer is at least 30 but no older than 60 is o.45, that the customer is either older than 60 or younger than 40 is 0.68 and that the customer is at least 60 is 0.22.

Answer:

(9+b)+(10+s)

Step-by-step explanation:

The percentage of matter in the ore that is neither gold nor diamond is 99.9388%.

In the question, we are given that a sample of ore is found to be 0.0022% gold and 0.059% diamond.

We are asked for the percentage of matter in the ore that is neither gold nor diamond.

We know that in any quantity, the total is shown as 100%.

If we assume the percentage of matter in the ore that is neither gold nor diamond to be x%, then using the above theory, we can say that;

x% + 0.0022% + 0.059% = 100%.

This can also be shown as:

x + 0.0022 + 0.059 = 100, which can be simplified as:

x + 0.0612 = 100, which can be solved by subtracting 0.0612 from both sides to get:

x = 100 - 0.0612 = 99.9388‬.

Thus, the percentage of matter in the ore that is neither gold nor diamond is 99.9388%.

Answer:

x = -4

Step-by-step explanation:

A perpendicular bisector is a line that divides the existing line or shape evenly and at 90° angles. First, we want to find the center point of our existing line. In this case, the center sits right at x = -4. Since the existing line is y = 3 and it is perfectly horizontal, we don’t need to do anything further. Our perpendicular bisector is x = -4.

*** When the existing line is y = [singular number], the perpendicular bisector will always be x = [midpoint of existing line], and vice versa.

the measure of m22 =  98°  by linear pair .

What is  linear pair?

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.

Given ,    mz1 = (4x + 50)°

               mz3 = (2x + 66)°.

a)  mz1  =   mz3

     (4x + 50)° =  (2x + 66)°

      4x - 2x  = 66 - 50

           2x =   16°

             x = 8°

b)     mz3 = (2x + 66)°.

      put value of x

     2x + 66 = 2 * 8 + 66

                   = 16  + 66  ⇒    82°

c)  mz2 =  ∠ 1 + ∠ 2 = 180°               { linear pair }

                4x + 50 + ∠2 = 180°

                  4 × 8 + 50 + ∠2 = 180°

                  82° + ∠2  = 180°

The value of m would be 7 if XZ is the angle bisector of the angle ∠WXY which are the angles ∠WXM and ∠YXZ would be 42°.

An angle bisector is defined as a line that divides an angle into two equal angles. Draw the given angle first, then cut it in half, and then draw the angle's bisector.

We have been given that XZ is the angle bisector of angle WXY.

⇒ ∠WXM = ∠YXZ

Solve for m

⇒ 10m -28 = 5m + 7

⇒ 10m - 5m = 28  + 7

⇒ 5m = 35

⇒ m = 35/5

⇒ m = 7

So ∠WXM = 10(7) -28 = 42

And ∠YXZ = 5(7) + 7 = 42

Therefore, the value of m would be 7.

The wavelength  λ , of a photon that has an energy of E = 4.26×10^−19 J is 21504.29 meter.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now, the given equation for photon energy, E , is

E = hcλ

Here, h = 6.626×10^−34 J⋅s (Planck's constant) and

c = 2.99×10^8 m/s (the speed of light)

Therefore, we have

E = hcλ

⇒ λ = E/hc

Put the values of E, h and c we get,

λ = 4.26×10^−19 / (6.626×10^−34*2.99×10^8)

Solving we get,

λ = 4.26×10^−19 / 19.81×10^(−34+8)

⇒ λ = 4.26×10^−19 / 19.81×10^-26

⇒ λ = (4.26/19.81)*10^(-19+26)

⇒ λ = 0.215042×10^5 meter

⇒ λ = 21504.29 meter

Thus, the wavelength  λ , of a photon that has an energy of E = 4.26×10^−19 J is 21504.29 meter.

The cost for using 40 HCF of water is $67.72

To solve this question, we use the following representations

Using the above representations, we have the following points

(x, y) = (14, 32.62), (48, 78.52)

For 40 HCF of water, we have

(x, y) = (40, y)

The slope of a linear equation is calculated using

m = (y2 - y1)/(x2 - x1)

So, we have

m = (78.52 - 32.62)/(48 - 14) = 1.35

m = (78.52 - y)/(48 - 40)

Substitute m = 1.35 in m = (78.52 - y)/(48 - 40)

So, we have:

1.35 = (78.52 - y)/(48 - 40)

Evaluate the difference

1.35 = (78.52 - y)/8

Multiply both sides by 8

10.8 = 78.52 - y

This gives

y = 78.52 - 10.8

Evaluate the difference

y = 67.72

Hence, the cost for using 40 HCF of water is $67.72
