4. A comprehensive study conducted by the National Institute of Child Health and Human Development tracked more than 1,000 children from an early age through elementary school (New York Times, November 1, 2005). The study concluded that children who spent more time than 30 hours a week in child care before entering school tended to score higher in math and reading when they were in the third grade. The researchers cautioned that the findings should not be a cause for alarm because the differences were found to be small. Explain how the difference between the math and reading score for the child care group and the overall mean for third graders could be small but the researchers could still reach the conclusion that the mean for the child care group is significantly higher than the overall mean.

Answer:

*Partially solved, cannot be fully solved, even in the most complex of mathematicians.

— Attempts at axiomatizing are useful even beyond mathematics: they help to clarify the basic assumptions and keep the mind in order. This is good and encouraging.

— This order may be much more complicated and counter-intuitive than the preceding chaos. This is not so encouraging, but not too bad: axiomatizing is a powerful tool, and its use requires accuracy.

— The road to rigour is infinite. This is neither encouraging nor discouraging: this is reality.

Step-by-step explanation:

‘One can say that, with the birth of quantum theory, Hilbert’s sixth problem was split into three different questions:

(i) Axiomatize classical probability.

(ii) Axiomatize the new (quantum) probability.

(iii) Clarify the connections between the two.’

The essence of the sixth problem as a programmatic call for the axiomatization of the physical sciences.

We can try to outline the possible ‘semantic of physical reality’ that complements semantics of physical theories, is simple, abstract and free from theoretical allusions. Let us just follow the machine learning abstractions. There are two alphabets: perceptions Inline Formula and actions Inline Formula.

The ‘person’ selects and sends ‘outwards’ the symbols from Inline Formula (actions) and receives symbols from Inline Formula (the answers to actions or just signals from ‘outside’).

There is the ‘freedom of will’: selection of a symbol from Inline Formula has no restrictions (Inline Formula models commands to actuators; the real actions and their results return to the person with the Inline Formula feedback).

10 problems, namely {3,7,10,11,13,14,17,19,20,21}, have a resolution that is accepted by a general consensus of the mathematical community. On the other hand, the solutions proposed for seven problems, namely {1,2,5,9,15,18,22}, are only partially accepted as resolving the corresponding problems.  

Therefore, my conclusion, is that my brain is fried, and this cannot be fully solved.

Answer:

Isosceles triangle

Answer:

[tex]P(x < 2.892) = 4.36\%[/tex]

Step-by-step explanation:

Given

[tex]N = 700[/tex] --- Population

[tex]\mu = 2.894[/tex] -- Mean

[tex]\sigma = 0.009[/tex] --- Standard deviation

[tex]n = 55[/tex] -- Sample

Required: [tex]P(x < 2.892)[/tex]

This question will be solved using the finite correction factor

First, calculated the z score

[tex]z = \frac{x - \mu}{\sqrt{\frac{N -n}{N -1}} * \frac{\sigma}{\sqrt n}}[/tex]

[tex]z = \frac{2.892 - 2.894}{\sqrt{\frac{700 -55}{700 -1}} * \frac{0.009}{\sqrt {55}}}[/tex]

[tex]z = \frac{-0.002}{\sqrt{\frac{645}{699}} * \frac{0.009}{7.42}}[/tex]

[tex]z = \frac{-0.002}{\sqrt{0.92} * \frac{0.009}{7.42}}[/tex]

[tex]z = \frac{-0.002}{0.95917 * 0.0012129}[/tex]

[tex]z = -1.71[/tex]

So:

[tex]P(x < 2.892) = P(z < -1.71)[/tex]

Using z table

[tex]P(x < 2.892) = 0.043633[/tex]

[tex]P(x < 2.892) = 4.36\%[/tex]

Answer: Answer: The required value of x is 12 units.

Step-by-step explanation:  Given that the figure A is a scale image of figure B.

We are to find the value of x.

Since figure A is the scale image of figure B, so both the figures are similar to each other.

Also, the corresponding sides of the similar figures are proportional, so we get

Thus, the required value of x is 12 units.

Answer:

  2/5

Step-by-step explanation:

The common ratio is r = (1/10)/(1/5) = 5/10 = 1/2. The first term is a1 = 1/5.

The sum of an infinite geometric series is given by ...

  S = a1/(1 -r)

  S = (1/5)/(1 -1/2) = (2/10)/(5/10) = 2/5

The sum of the series is 2/5.

_____

It might stick in your head that the sum of 1 + 1/2 + 1/4 + 1/8 + 1/16 + ... is 2. The given series is 1/5 times that.

Answer:

The written inequality can be written as 0.12x + 25 <= 150.

Step-by-step explanation:

To solve the inequality you would plug in the 125 miles for x so 0.12(125) + 25 <= 150 0.12(125) would equal 15 so 15 + 25 <= 150 150/40 would equal 3.75 days but you cant have .75 of a day so Violet would have three days max to afford to rent the car while staying in her budget.

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven. The inequality can be written as 0.12x + 25 <= 150.

The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven.

Violet wants to rent a car, knowing that:

She plans to drive 125 miles.

She has at most $150 to spend.

To solve the inequality in the 125 miles for x

So, 0.12(125) + 25 <= 150

= 0.12(125)

= 15

So, 15 + 25 <= 150

= 150/40

= 3.75 days

So, Violet would have three days max to afford to rent the car while staying within her budget.

Answer:

44'2"

Step-by-step explanation:

32'11"+11'3' = 43'14" = 44'2"

Answer:

44'2"

Step-by-step explanation:

Starting with 32' 11", we'll add the 3" from the second number first. That will give us 32' + 14". Every 12" = 1 more foot, so that converts to 33' 2". Now add the 11' from the 11'3", and you have 44' 2". Does that make sense? Happy to answer any questions.

Answer:

Ф = 0.3 radians

Step-by-step explanation:

The arc length formula is s = rФ.  Solving for the angle measure Ф, we get:

Ф = s/r

and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians

True. Hope this helps:)

Answer:

slope=7/4

Step-by-step explanation:

you can find the slope of the line from a graph using the formula rise/run, where rise is the change in y and run is the change in x

let's start with a clear point; for example, (-1,-3)

we need to go up, down, left, or right to get the rise/run

up/down is considered the rise

left/right is considered the run

if we go up or to the right, that's considered a positive move

if we go down or to the left, that's considered a negative move

we'll go from (-1,-3) to another clear point, like (3,4) for example

starting at (-1,-3):

go up 7, to the point (-1,4)

then move 4 to the right to get to the point (3,4)

we went up 7, so our rise is 7

we moved to the right 4, so that is our run

our slope then is 7/4
