Answer:

617.902

Step-by-step explanation:

(6 * 100) + (1 * 10) + (7 * 1) + (9 *1/10) + (2 *1/1000)=308951/500

308951/500=617.902

The standard form of given number is 6.17 ×10².

Standard form is a way of writing down in easy form of very large or very small numbers.

Let E is the standard form of given number

E = (6 × 100) + (1 × 10) + (7 × 1) + (9 ×1/10) + (2 ×1/1000)

E =600+10+7+0.9+0.002

E =617.902

E =0.617 × 10³ = 6.17 ×10²

E = 6.17 ×10²

Hence, the standard form of given number is 6.17 ×10²

Answer:

The correct option is  c

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 185.6 \ mm[/tex]

   The standard deviation is  [tex]\sigma = 12.7 \ mm[/tex]

   The sample size is  n = 10  

    Generally the standard error of the mean is mathematically represented as

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

=>    [tex]\sigma_{x} = \frac{ 12.7}{\sqrt{ 10 } }[/tex]

=>    [tex]\sigma_{x} = 4.016[/tex]

Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as

     [tex]P(X < 180 ) = P(\frac{ X - \mu }{\sigma_{x} } < \frac{180 - 185.6}{4.016} )[/tex]

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

    [tex]P(X < 180 ) = P(Z < - 1.394 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -1.394  is  

          [tex]P(X < 180 ) = P(Z < - 1.394 ) = 0.081659[/tex]

=>      [tex]P(X < 180 ) = 0.0823[/tex]

Answer:

155

Step-by-step explanation:

- because of the angle rules, (6x+1) = (2x+17)

- with this, you can now solve to get x = 4

- also because of the angle rules, y = 180 - (2x+17)

- replace the x with 4 and calculate and you'll get y = 155

Answer 10.75

......................................

Answer:

10 and 3/4

Step-by-step explanation:

For the fractions, get a common denominator (bottom number): 1/2=2/4

So 2/4 plus 1/4 equals 3/4 and 5+5 equals ten.

10+3/4=10 3/4

Decimal form: 10.75

Answer:

Step-by-step explanation:

Checkpoint A-> time being 1:00pm total miles driven being 120 and

checkpoint B-> time being 3:00pm and the total miles being 208

The distance between two checkpoint A  and B is 208 - 120 = 88 miles

Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours

We need to find car speed between the checkpoints

We know Distance = speed * time

Speed = 44 miles per hour

Answer:

The answer is 1 miles

Answer:

d=2√10

Step-by-step explanation:

The distance between the two points will be given by:

d=√[(x-x1)^2+(y-y1)^2]

point z1=(3-2i) has the coordinates of (3,-2)

point z2=(5-8i) has the coordinates of (5,-8)

thus the distance between them will be:

d=√[(-8-(-2)²+(5-3)²)]

d=√[(-6)²+2²]

d=√(36+4)

d=√40

d=2√10

Answer:

3√2

Step-by-step explanation:

distance formula: d = √(a₁ - a₂)² + (b₁ - b₂)²

a = x, b = y

d = √(x₁ - x₂)² + (y₁ - y₂)²
