In basketball there are 1,2, and 3 point shots. In the last game sarah scored a total of 25 points by making 13 total baskets. S

ollegr [7]

Answer:

3 , 6 , 4

Step-by-step explanation:

Given:

There are three groups of shots in basketball.

First group carry = 1 point

Second group carry = 2 points

Third group carry = 3 points

Sarah scored a total of 25 points by making 13 total baskets.

She made twice as many 2 point shots as she did 3 point shots.

Question asked:

How many of each type of shot did she make ?

Solution:

Let number of baskets, she made which carry 3 points = $x$

Then, number of baskets, she made which carry 2 points = $2x$

Total number of baskets, she made = 13

Then, number of baskets, she made which carry 1 points = $13-(x+2x)=13-3x$

Now,

Sarah scored a total number of points = 25

$3\times x+2\times2x+1(13-3x)=25\\3x+4x+13-3x=25\\4x+13=25$

Subtracting both sides by 13

$4x=25-13\\4x=12$

Dividing both sides by 4

$x=3$

By substituting the value:-

Number of baskets, she made which carry 3 points = $x$ = 3

Number of baskets, she made which carry 2 points = $2x$ = $2\times3=6$

Number of baskets, she made which carry 1 points = $13-3x=13-3\times3=13-9=4$

Thus, she made 3 baskets of 3 points, 6 baskets of 2 points and 4 baskets of 1 point.

Zina [86]

Answer: c. Describe the data

Step-by-step explanation:

Description of data involves the use of descriptive statistics to analyse/summarize a set of data (from samples) generated during a research.

Some of the process involved in the description of data involves the measure of central tendency ( averages, mean, median mode) and also measure of dispersion and graphing. Therefore, the case above described the data collected.

It is valid.
The three angles must add up to 180. So, if one is more than 90, the other two have to be less than 90.
