Answer:

[tex]Distance = 880ft[/tex]

Step-by-step explanation:

Given

[tex]Speed = 20\frac{miles}{hour}[/tex]

[tex]Time = 30\ seconds[/tex]

Required

Determine the distance

To answer this question, we make use of speed-distance relationship

[tex]Speed = \frac{Distance}{Time}[/tex]

Make Distance the subject

[tex]Distance = Speed * Time[/tex]

[tex]Distance = 20 miles/hour * 30 seconds[/tex]

Convert seconds to hour

[tex]Distance = 20 miles/hour * \frac{30}{3600} hour[/tex]

[tex]Distance = 20 miles * \frac{30}{3600}[/tex]

[tex]Distance = \frac{20 miles * 30}{3600}[/tex]

[tex]Distance = \frac{600\ miles}{3600}[/tex]

[tex]Distance = \frac{1}{6} miles[/tex]

Convert to foot

[tex]Distance = \frac{1}{6} * 5280\ ft[/tex]

[tex]Distance = \frac{1* 5280\ ft}{6}[/tex]

[tex]Distance = \frac{5280\ ft}{6}[/tex]

[tex]Distance = 880ft[/tex]

Answer:

  B.  45.8 cm

Step-by-step explanation:

The Pythagorean theorem is helpful. For legs a, b, and hypotenuse c, it tells you ...

  c² = a² +b²

  50² = 20² +b²

  b² = 2500 -400 = 2100

  b = √2100 ≈ 45.8

The length of the other leg is about 45.8 cm.

Slope of the line = 2

Step-by-step explanation:

Slope of a line through two points lying on the line [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the figure attached,

Given line is passing through two points (0, 1) and (1, 3).

Therefore, slope of the line will be,

Slope = [tex]\frac{3-1}{1-0}[/tex]

          = 2

The slope of the line given in the graph is -0.5.and this can be determined by using the point-slope form and slope-intercept form.

Given :

To determine the slope of the line, the point-slope form can be used. The point-slope form is given by:

[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.

Now, put the values of the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the above equation.

[tex]\dfrac{y-1}{x-0}=\dfrac{0-1}{0.5-0}[/tex]

0.5(y - 1) = -x

[tex]y = -\dfrac{1}{2}x +1[/tex]

Now, compare equation (1) with the slope-intercept form of the line.

m = -0.5

c = 1

So, the slope of the line is -0.5.

Explanation:

Let's complete the square

y = x^2 + 8x

y + 16 = x^2 + 8x + 16 .... adding 16 to both sides

y + 16 = (x+4)^2

y = 1(x+4)^2 - 16

We added 16 to both sides to allow the right hand side to factor into a perfect square.

The last line shown above is in the form y = a(x - h)^2 + k where

a = 1

h = -4

k = -16

Note the positive 'a' value indicates we have a minimum.

The vertex is (h,k) = (-4, -16)

The lowest y value possible is at the vertex.

So the smallest y value is y = -16.

This means the smallest possible value of x^2+8x is -16.

b

Answer:

g/(b + g)

Step-by-step explanation:

We are told the group of individuals contain b number of boys and g number of girls.

Now the number of ways of selecting 1 girl out of g number of girls is;

gC1 = g!/(g - 1)! = (g × (g - 1)!)/(g - 1)!

(g - 1)! will cancel out to give;

gC1 = g

Now, since total number of boys and girls is b + g, and we have chosen one girl out, the remaining number of people will be; b + g - 1.

Thus, number of ways to arrange the remaining people will be;

(b + g - 1)!

Now, the probability that the person in the ith position (1 ≤ I ≤ b+g) is a girl will be;

(gC1 × (b + g - 1)!)/(b + g)!

We know that gC1 = g from earlier derivation.

Expanding this gives;

[g(b + g - 1) × (b + g - 2)!]/[(b + g) × (b + g - 1) × (b + g - 2)!]

(b + g - 1) × (b + g - 2)! will cancel out to give;

g/(b + g)

Step-by-step explanation:

8.156 million = 8,156,000

hope this helps!

The value of 5 is 50, 000.

In mathematics, place value refers to the relative importance of each digit in a number. These locations begin at the unit's location (ones place). The place values of a number's digits are expressed in the following order: ones/units, tens, hundreds, thousands, ten thousands, and so on.

Given:

The population of London is currently estimated at 8.156 million.

Expanding 8.156 million.

= 8.156,000

Here the place value of 5 is ten thousand.

Hence, the value of 5 is 50, 000.

Complete Question

The proportion of adult women in the United States is 51% (p=0.51).What is the probability that a random sample of 400 U.S. youth will provide a sample proportion (p¯) that is within 0.03 of the population proportion (p)?

Answer:

The probability is  [tex]P( 0.48 < p < 0.54 ) = 0.77[/tex]  or  [tex]P( 0.48 < p < 0.54 ) = 77\%[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  400

    The population proportion is  p = 0.51

Generally the standard deviation of this sampling distribution is mathematically represented as

          [tex]\sigma = \sqrt{\frac{p(1-p)}{n} }[/tex]

=>      [tex]\sigma = \sqrt{\frac{0.51(1-0.51)}{400} }[/tex]

=>      [tex]\sigma = 0.02499[/tex]

Generally the lower limit for the range of the population proportion within 0.03 is

    [tex]a = p - 0.03[/tex]

=>[tex]a = 0.51 - 0.03[/tex]

=>[tex]a = 0.48[/tex]

Generally the  upper  limit for the range of the population proportion within 0.03 is

    [tex]b = p + 0.03[/tex]

=>[tex]a = 0.51 + 0.03[/tex]

=>[tex]a = 0.54[/tex]

Generally the  probability that a random sample of 400 U.S. youth will provide a sample proportion (p¯) that is within 0.03 of the population proportion (p) is mathematically represented as

     [tex]P( a < p < b) = P( \frac{a - p }{\sigma } < \frac{\^ p - p }{\sigma} < \frac{b - p}{\sigma } )[/tex]

=>   [tex]P( 0.48 < p < 0.54 ) = P( \frac{0.48 - 0.51 }{0.02499 } < \frac{\^ p - p }{\sigma} < \frac{0.54 - 0.51}{0.02499 } )[/tex]

[tex]\frac{\^ p -p }{\sigma }  =  Z (The  \ standardized \  value\  of \  \^ p )[/tex]

=>   [tex]P( 0.48 < p < 0.54 ) = P( -1.2 < Z < 1.2 )[/tex]

=>   [tex]P( 0.48 < p < 0.54 ) = P( Z < 1.2) - P(Z < -1.2 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1.2 and  -1.2  is

     [tex]P( Z < 1.2) =0.88493[/tex]

and  

    [tex]P( Z < -1.2) =0.11507[/tex]

So

   [tex]P( 0.48 < p < 0.54 ) = 0.88493 - 0.11507[/tex]

=>  [tex]P( 0.48 < p < 0.54 ) = 0.77[/tex]
