John and Amelia have a baby daughter Sonia John is 23 kg heavier than Amelia who is four times as heavy as Sonia their combined weight is 122. how heavy is each person​

Answers

Answer 1

x+4x+4x+23

9x+23=122

122-23=99

9\99=11

J=67

A=44

S=11

11+44+67=122 kg

Answer 2

The weight of John, Amelia and Sonia are 67 kg, 44 kg and 11 kg respectively.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that

Let j , a and s be the weights of John, Amelia and Sonia respectively.

John is 23 kg heavier than Amelia.

j = a + 23

Amelia is four times as heavy as Sonia.

a = 4s ⇒ s = a/4

Their combined weight is 122.

j + a + s = 122

Substituting the above expressions of j and s in terms of a in the equation j + a + s = 122, we get,

(a + 23) + a + (a/4) = 122

2a + a/4 + 23 = 122

9a/4 = 122 - 23

2.25a = 99

a = 44

j = 44 + 23 = 67

s = 44/4 = 11

Hence the weight of each person is 67 kg, 44 kg and 11 kg.

Step-by-step explanation:

13) Because they all lie on the same line, AC would be AB+BC, or 16+12, or 28.

14) Same thing as 13, 13+9=22

15) Same thing as others but make an equation

-1+2x+11=3x+3

Simplifying the equation, we get x=7. Now, we plug in x=7 to 3x+3 to get AC.

3(7)+3=21+3=24

16) build the equation:

x+14+x+10=22

2x+24=22

2x=-2

x=-1

Now plug in x=-1 to x+14.

-1+14=13

Find the value(s) of "k" that will cause the equation 4x^2 +kx + 4 to have one real solution.

Answers

Answer:  k = {8, -8}

Step-by-step explanation:

In order for a quadratic equation to have exactly one solution, the discriminant must equal zero.       →        b² - 4ac = 0

  4x² + kx + 4 = 0

  ↓       ↓      ↓

a=4    b=k    c=4

b² - 4ac = 0

k² - 4(4)(4) = 0

           k = √64

           k = ± 8

If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet

Answers

Complete Question

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 220 feet and a standard deviation of 40 feet. Let X = distance in feet for a fly ball.

If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet

Answer:

The value is [tex]P(X < 194 ) = 0.25785[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 220 \ feet[/tex]

   The standard deviation is  [tex]\sigma = 40 \ feet[/tex]

   

Generally the probability that this ball traveled fewer than 194 feet is mathematically represented as

       [tex]P(X < 194 ) = P(\frac{X -\mu}{\sigma } < \frac{194 - 220}{40} )[/tex]

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

         [tex]P(X < 194 ) = P(Z < -0.65 )[/tex]

From the z-table the probability of  [tex](Z < -0.65 )[/tex]

      [tex]P(Z < -0.65 ) = 0.25785[/tex]

So  

     [tex]P(X < 194 ) = 0.25785[/tex]

The Israeli/Palestinian conflict is ALL about religion?TrueFalse The ultimate goal of operations management is to provide high-quality goods and services instantaneously in response to customer demand. Over the years, low cost often came at the expense of quality and flexibility. Furthermore, suppliers didn't always deliver when they said they would, so manufacturers had to carry large inventories of raw materials and components to keep producing. Such inefficiencies made U.S. companies vulnerable to foreign competitors who were using more advanced production techniques As a result of new global competition, companies have had to make a wide variety of high-quality custom-designed products at a very low cost. Something had to change on the production floor to make that possible. Several major developments have made U.S.companies more competitive: (1) computer-aided design and manufacturing (2) flexible manufacturing, (3) lean manufacturing, and (4) mass customization, (5) CAD(6) CAMMatch the company or role with the most appropriate manufacturing technique.
