Question 10

Can somebody help me out with these notes? I had attempted it but I’m not sure if it’s right and I have to show work.

Step-by-step explanation:

The +7 is the y-intercept

It is where the line starts in your example and is 7 units away from 0

Since the line is decreasing the 3 is negative

How do you simplify 3 1/4 x 3/5 someone please help me

kifflom [539]

Answer:

We want to simplify:

(3 + 1/4)*(3/5)

The first step is to write the first term as a single rational number.

We know that:

3*1 = 3

and 4/4 = 1

then:

3*1 = 3*(4/4) = (3*4)/4 = 12/4

We do this because we want to have the same denominator in both numbers, so we can directly add them.

Then we get:

(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)

And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:

(13/4)*(3/5) = (13*3)/(4*5)

If we solve the multiplications we get:

(13*3)/(4*5) = (39/20)

Now, we can notice that in the numerator we have two prime numbers, 13 and 3.

And in the denominators, we have a 4 (which is equal to 2*2) and a 5.

So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.

Then we have:

(3 + 1/4)*(3/5) = (39/20)

In a basketball shooting competition, each competitor shoots ten balls which are numbered from 1 to 10. The number of points ear

sp2606 [1]

Answer:

score 35 is not possible

Step-by-step explanation:

Here, the competitor misses exactly two shots

what we have here is that, if we added from the numbers between 1-10 , excluding exactly two numbers, which of the numbers in the option cannot be obtained by this addition

a) 52

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

Total is 55

if we removed (2 and 1)

we get 52

This is a possible score

b) 44

Here, we just have to remove 11

if we take off 10 and 1, we can have 44

c) 41

if we removed 4 and 10 ; we get 41

d) 38

if we remove 17, we get 38

so let us remove 10 and 7

e) 35

here, we have to remove 20

Now, no two numbers added between 1 and 10 exactly will give 20

The highest sum to be deducted is 9 + 10 which is 19

So the lowest possible score is 55-19 = 36

This means that the term 35 is not possible

Answer:

Section a)

Solution;

A correlation coefficient of 0.4 implies a relatively weak positive association between two sets of data. There is a notable small increment in one data set as the other increases.

Section b)

Solution;

A correlation coefficient of -0.96 implies a strong negative association between two sets of data. An increase in the values of one data set amounts to a decrease in the values of the other data set by approximately the same magnitude.

Section c)

Solution;

A correlation coefficient of -0.02 implies a weak negative association between two sets of data. An increase in the values of one data set amounts to a negligible decrease in the values of the other data set.

Section d)

Solution;

A correlation coefficient of 1.0 implies a perfect positive association between two sets of data. An increase in the values of one data set amounts to an increase in the values of the other data set by exactly the same magnitude. A scatter plot would reveal that the line y =x fits the data well.

Section e)

Solution;

A correlation coefficient of 0.86 implies a strong positive association between two sets of data. An increase in the values of one data set amounts to an increase in the values of the other data set by approximately the same magnitude.

Step-by-step explanation:

Correlation coefficient measures the degree of association between two variables or data sets. Correlation coefficients can be positive or negative and may imply weak or strong association between two data sets.

A correlation coefficient of less than 5 is implies a weak association while a value greater than or equal to 5 implies a strong association. Finally, a correlation of 1.0 implies perfect association.
