Option -A is correct that is the order of the children by age, from oldest to youngest is Paul, Phillip, Annie, Chris.

Given that,

There are 4 children's. The names of the children's are Philip, Annie, Paul and Chris.

Philip is twice as old as Annie. Paul is 4 years older than Phillip and Chris is 2 years younger than Annie.

We have to find which represents the order of the children by age, from oldest to youngest.

We know that,

Lets us take the ages if the children's as a,b,c,d of Philip, Annie, Paul and Chris.

Philip is twice as old as Annie.

That means a = 2b

Paul is 4 years older than Phillip and

That mean c =4+a

Chris is 2 years younger than Annie.

That means d=b-2

So,

If we take the age of Philips as 20

Then Annie is 10, Paul is 24 and Chris is 8.

Therefore, Option -A is correct that is the order of the children by age, from oldest to youngest is Paul, Phillip, Annie, Chris .

Answer:

Why i dont know

Step-by-step explanation:

An 80% confidence interval is found to be (12, 20). Thus, the margin of error is 8.

Suppose the confidence interval at P% for some parameter's values is given by

[tex]x \pm y[/tex]

That means that parameter's estimated value is P% probable to lie in the interval

[x-y,x+y]

In most of the cases, the confidence interval is constructed around the mean, and the absolute distance from the mean on right or left side of the mean is called the margin of error.

Thus, we get: Confidence interval [tex]limits= \overline{x} \pm MOE[/tex]

The width of the confidence interval

20-12 = 8 units.

That cuts in half to get 8/2 = 4 which is the margin of error.

The center of the confidence interval

(12+20)/2

= 32/2

= 16.

So, 16+4 = 20, which is the right endpoint.

Also, 16-4 = 12, which is the left endpoint.

Step-by-step explanation:

Answer:

$2.79

Step-by-step explanation:

An easy way to figure out percentages is by dividing by 100 then multiplying by the percentage you are trying to figure out.

15.50/100 =0.155, 0.155 times 18 is equal to 2.79.

Answer:

x = 2√11

y = 4√47

Step-by-step explanation:

x^2 + 10^2 = 12^2

x^2 + 100 = 144

x^2 = 144 - 100

x^2 = 44

x = 2√11

x^2 + 12^2 = y^2

44 + 144 = y^2

188 = y^2

y = 2√47

Answer:

Step-by-step explanation:

Each mark (x) on the plot presents the distance that each student jumped.

There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.

Number of students that jumped 5½ ft = 3

Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

= 3/24

Simplify/reduce the fraction

Answer: [tex]0.66\ lb[/tex]

Step-by-step explanation:

Given

1 kg=2.2 Pounds(lb)

We need to convert 300 g into lbs

1 kg=1000 g

So, 300 g is equal to 0.3 kg

Now, convert kg into pounds

[tex]\Rightarrow 0.3\times 2.2\ lb\\\Rightarrow 0.66\ lb[/tex]

The liners function are not direct variation

The relationship between two variables in which one is a constant multiple of the other is referred to as direct variation.

For instance, two variables are said to be in proportion when one affects the other. b = ka is the equation

If b is directly proportional to a, then k is the constant of variation and the value of k = b/a for all value of b and a

In the problem, the variables are compared as follows

feet = k * sec

k = feet / sec

For the first values, k = 33 / 3 = 11

For the second values, k = 36 / 6 = 6

since 11 ≠ 6 the function is not a direct variation

The pre-image and picture will become congruent to one another by the following transformations: Reflection, Rotation and Translation

A sequence is a collection of numerals (referred to as "terms"), for example, 2, 5, 8. A specific pattern that some sequences follow may be leveraged to make them infinitely long. To continue the series, add 3 and use the example of 2,5,8. Formulas that show where to look for words inside a sequence can be found there. Informally, a sequence in mathematics is a collection of items that are in some order (or events). It has components, much like a set (also called elements or terms).

Any of the aforementioned modifications result in an exact replica of the pre-image in the picture. The only thing that has changed about the figure is that it has been moved, rotated, or somehow reflected. The figurine is still the same size and form as before. Isometries are the name for these transformations.

Barren's net worth statement exists shown to the right.

Your total worth, including both financial and non-financial assets, equals your net worth less any outstanding obligations.

Using a net worth statement, you can view your financial situation at any given time. It is comparable to a "financial snapshot," showing the dollar amounts of your assets and liabilities (liabilities or debts).

Assets - Liabilities = Net Worth is the equation for calculating net worth.

The total of Lauren Juliana's debts will be subtracted from the total of her assets to determine her net worth (cash and jewelry).

= ($ 14,692 + $ 2,575) - ($ 10,981 + $ 1,682 + $ 787)
