How to show numbers are related to each other

1 answer:

4 0

Human and non-human species possess a mental system of number representations that appear early in the lifespan and that supports approximate number skills, such as numerical estimation or number comparison. With the later acquisition of language and of symbolic numbers, human beings also develop exact number skills that allow using numbers precisely, such as in counting and arithmetic. The current review points out the behavioral data which either support or challenge these contrasting proposals. In an attempt to provide a comprehensive overview of these mixed data, we carefully took into account the heterogeneity of the available studies regarding the kind of tasks, stimuli or ages of assessment. Also, you can show how the numbers are related simply by identifying the tenth place value of each digit.

Answer:

Here we have the relation:

m = 140*h

Where m is the distance in miles, and h is time in hours.

And we want to complete a table like:

$\left[\begin{array}{ccc}in, h&out, m\\&\\&\\&\\&\end{array}\right]$

The way to complete this, is to evaluate the function:

m = 140*h

in different values of h, and then record both values of h and m in the table.

Let's use values of h that increase by 0.5, then:

if h = 0.5

m = 140*0.5 = 70

We have the pair: h = 0.5, m = 70

if h = 1

m = 140*1 = 140

We have the pair: h = 1, m = 140

if h = 1.5

m = 140*1.5 = 210

Then we have the pair h = 1.5, m = 210

if h = 2

m = 140*2 = 280

We have the pair: h = 2, m = 280

Now we can complete the table, and it will be:

$\left[\begin{array}{ccc}in, h&out, m\\0.5&70\\1&140\\1.5&210\\2&280\end{array}\right]$

Rewrite the equation 4x + 5x2 = 8x – 7 in standard form and

Makovka662 [10]

Answer:

The correct option is a=5, b = -4, c=7 ....

Step-by-step explanation:

The standard form is ax²+bx+c=0

where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

The given expression is:

4x + 5x2 = 8x – 7

To make it a standard equation we will move all the values to the left hand side and 0 will be left at the right hand side.

4x+5x²-8x+7=0

Now solve the like terms and arrange the equation according to the standard form:

ax²+bx+c=0

5x² - 4x +7 =0

Here a = 5

b = -4

c= 7

Thus the correct option is a=5, b = -4, c=7 ....

Answer:

(a) The proportion of women who are tested, get a negative test result is 0.82.

(b) The proportion of women who get a positive test result are actually carrying a fetus with a chromosome abnormality is 0.20.

Step-by-step explanation:

The Bayes' theorem states that the conditional probability of an event E $_{i}$ , of the sample space S, given that another event A has already occurred is:
