Answer: It's 129°

Step-by-step explanation: Because we know x and 51 are supplementary angles (add up to 180), We can do x + 51 = 180, to figure out that x is equal to 129°.

Answer:

Step-by-step explanation:

Answer:

Depending on what form you want it in:

Exact Form:

41/24

Decimal Form:

1.708  3

.. (3 is infinite)

Mixed Number Form:

1  17/24 (The 1 in front is supposed to be a whole)

Step-by-step explanation:

5/6 + 7/8

First, you must make both denominators equal a same number.

6 x _ = 8 x _

The same number but also the least is least common denominator is 24.

4 (5/6) + (7/8) 3

20/24 + 21/24

= 41/24

Answer:

49:52

Step-by-step explanation:

Given that:

Total number of contacts on phone = 52

Family members in phone book : dad, mom, brother

Total number of family members = 3

Hence, non family members = 52 - 3 = 49

Number of family members to total phone contact

Selecting a contact that is not a family member :

49 : 52

Answer:

the answer is 49:3 :)

Answer:

15:2 or 15 to 2

Step-by-step explanation:

They are asking for a ratio based on how many chaperones per student (in this case 15 students) In other words 15 students for every 2 chaperones.

Step-by-step explanation:

Consider two points on a curve, (xᵢ, yᵢ) and (xᵢ₊₁, yᵢ₊₁).  The distance between them can be found with distance formula:

d = √((xᵢ₊₁ − xᵢ)² + (yᵢ₊₁ − yᵢ)²)

d = √((Δx)² + (Δy)²)

Factor out Δx:

d = √(1 + (Δy/Δx)²) Δx

Adding up the distances from i=1 to i=n, the total arc length can be approximated as:

s ≈ ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Taking the limit as n approaches infinity, we get the exact value of s:

s = lim(n→∞) ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Which can be written as a definite integral:

s = ∫ₐᵇ √(1 + (dy/dx)²) dx

Answer:

11/18

Step-by-step explanation:

4/9 + 1/6

Get a common denominator of 18

4/9 * 2/2 = 8/18

1/6 * 3/3 = 3/18

8/18+3/18

11/18

Answer:

11/18

4/9 + 1/6

Get a common denominator of 18

4/9 * 2/2 = 8/18

1/6 * 3/3 = 3/18

8/18+3/18

11/18

Answer:

x = 15

Step-by-step explanation:

The definition of alternate interior angles means that both of these labeled angles will be equal. Therefore, 60 = (3x + 15)

60 = 3x + 15

Divide this by 3 on both sides

20 = x + 5

Subtract 5 from both sides

15 = x or x = 15

Answer:

i think the answer is -5

insert -4 where the x is in the equation and solve

Answer:

2/3

Step-by-step explanation:

Simplify the following:

3/4 - 1/12

Put 3/4 - 1/12 over the common denominator 12. 3/4 - 1/12 = (3×3)/12 - 1/12:

(3×3)/12 - 1/12

3×3 = 9:

9/12 - 1/12

9/12 - 1/12 = (9 - 1)/12:

(9 - 1)/12

9 - 1 = 8:

8/12

The gcd of 8 and 12 is 4, so 8/12 = (4×2)/(4×3) = 4/4×2/3 = 2/3:

Answer:  2/3

Answer:

The  probability is  Right- tailed

The mean overtime hours for the sample will be at least 9.3 hours is

    [tex]P(X \ge 9.3 ) = 0.3333[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = 9.2 \ hours[/tex]

    The  standard deviation is  [tex]\sigma = 1.6 \ hours[/tex]

    The sample size is n  =  49

      The sample  mean is  [tex]\= x = 9.3[/tex]

Generally the standard error of the mean is mathematically represented as

      [tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]\sigma_{\= x} = \frac{1.6 }{\sqrt{49} }[/tex]

=>    [tex]\sigma_{\= x} = 0.22857[/tex]

This is a right -tailed probability because the sample mean is greater than the        population mean

 Generally  the probability that the mean overtime hours for the sample will be at least 9.3 hours is mathematically represented as  

           [tex]P(X \ge 9.3 ) =1 - P(X < 9.3 )[/tex]

So

           [tex]P(X < 9.3 ) = P( \frac{ X - \mu }{ \sigma_{\= x }} < \frac{ 9.3 - 9.2 }{ 0.22857} )[/tex]

Here   [tex]\frac{X - \mu }{\sigma _{\= x}} = Z[/tex]

           [tex]P(X < 9.3 ) = P( Z < 0.43750)[/tex]

From the z-table  

            [tex]P(X < 9.3 ) = P( Z < 0.43750) = 0.667[/tex]

So

   [tex]P(X \ge 9.3 ) =1 - 0.667[/tex]

   [tex]P(X \ge 9.3 ) = 0.3333[/tex]
