Line ABC is a straight line

Answer:

The standardized value is -2

Step-by-step explanation:

Given

[tex]mu = 20[/tex] -- mean

[tex]\sigma = 2[/tex] --- standard deviation

Required

Determine the standardized value of X = 16

The standardized value (S) is calculated using:

[tex]S = \frac{X - mu}{\sigma}[/tex]

This gives:

[tex]S = \frac{16 - 20}{2}[/tex]

[tex]S = \frac{- 4}{2}[/tex]

[tex]S = -2[/tex]

The standardized value is -2

the answer is 359.7

Step-by-step explanation:

Answer:

  1,000 cans

Step-by-step explanation:

Since there are 32 cans per pound and each pound is 32 cents. You divide 32/32 which tells you each can is 1 cent. So 100 dollars divided by 1 cent is 1,000 cents or 1,000 cans since each can is 1 cent.  

Answer:

1000 can

Answer:

85

Step-by-step explanation:

From the question given above, the following data were obtained:

Ratios of the angle => 2 : 4 : 5 : 6

Difference between the largest angle and the smallest angle​ =?

Next, we shall determine the various angles in the quadrilateral. This can be obtained as follow:

Ratios of the angle => 2 : 4 : 5 : 6

Total ratio = 2 + 4 + 5 + 6

Total ratio = 17

Angle in a quadrilateral = 360

For ratio 2:

Angle = 2/17 × 360 ≈ 42

For ratio 4:

Angle = 4/17 × 360 ≈ 85

For ratio 5:

Angle = 5/17 × 360 ≈ 106

For ratio 6:

Angle = 6/17 × 360 ≈ 127

SUMMARY:

The angles are => 42°, 85°, 106° and 127°

Finally, we shall determine the difference between largest angle and the smallest angle​. This can be obtained as follow:

Smallest angle = 42°

Largest angle = 127°

Difference between the largest angle and the smallest angle​ =?

Difference = Largest – Smallest

Difference = 127 – 42

Difference = 85

Thus, the difference between the largest angle and the smallest angle​ is 85.

Step-by-step explanation:

In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.

Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.

For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.

So, the following should not be relevant for determining the mean:

Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.

Answer:

x=¼

Step-by-step explanation:

3x+1+10x=x+4 (Group like terms )

3x+10x-x=4-1

12x=3(Divide both sides by 12)

[tex] \frac{12x}{12} = \frac{3}{12} [/tex]

[tex]x = \frac{1}{4} [/tex]

Slope: 1/4

A point on the line: (0, 17/4)

I rewrote the equation in slope intercept form (y=mx+b), it was y=1/4x+17/4

The slope is m, and b is the y intercept (where the line crosses the y - axis), that's the easiest point to find if you have the equation.

Answer:

The charge needed will be [tex]q=6.6\: \mu C[/tex]

Step-by-step explanation:

The equation of the electric force is given by:

[tex]F=k\frac{qQ}{r^{2}}[/tex]

We have the force [tex]F = 9.9 10^{-6}\: N[/tex]  and the distance r = 200. k is the Coulomb constant. Q and q are the charges.

We assume we have the same charge of the particles,  so we have:

[tex]q^{2}=\frac{Fr^{2}}{k}[/tex]

[tex]q^{2}=\frac{9.9*10^{-6}200^{2}}{9*10^{9}}[/tex]

[tex]q=6.6*10^{-6}\: C[/tex]

Therefore, the charge needed will be [tex]q=6.6\: \mu C[/tex]

Answer:

x = 18

y = 6

Step-by-step explanation:

In triangle UTR, measures of all angles are equal (60°). (given)

Therefore, it is an equilateral triangle.

So, it's sides will also be equal.

In triangle TRS, m angle T = m angle S

So, RT = RS = 11 (sides opposite to the equal angles are equal)

In triangle URT,

UT = RT (sides of equilateral triangle)

x - 7 = 11

x = 11 + 7

x = 18

In triangle TRS,

m angle T = m angle S = 5y°

m angle R = 180° - 60° = 120° (Linear pair angles)

5y° + 5y° + 120° = 180°

10y° = 180° - 120°

10y° = 60°

y = 60/10

y = 6

Answer:

2x + 1
