What is the Pythagorean theorem of 9in and 12in triangle

vagabundo [1.1K]

15. The formula is a^2+b^2=c^2. So you just plug in the 9 and 12 in the a and b. You get 225. You then take the square root of that and get 15.

No one helped me with the last question but i got it can someone help me with this

y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

$-14-(42) =-14+42 =28\\14+14= 28$

The change in y is:

$-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56$

The slope is:

$Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2$

Putting slope in equation of linear function

$y =2x+b$

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

$28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0$

Hence,

the linear equation for function is:

y = 2x

Sue played four games of golf for these games her modal score was 98 and her mean score was 100 her range of score was 10 what w

earnstyle [38]

Answer : Remaining two observation becomes 97 and 107.

Explanation :

Since we have given that

Mean = 100

Modal value = 98

Range = 10

As we know that ,

Range = Highest-Lowest

Let highest observation be x

Let lowest observation be y

So equation becomes x-y=10 ----equation 1

So, observation becomes

x,98,98,y

Now, we use the formula of mean i.e.

Mean = $\frac{\text{Sum of observation}}{\text{N.of observaton}}$

So, mean = $\frac{x=98=98+y}{4}=400\\\frac{196+x+y}{4}=100\\x+y=400-196\\x-y=204$

So our 2nd equation becomes

x+y=204

On using elimination method of system of linear equation on these two equation we get,

x=97

and

$x+y=204\\y=204-x\\y=204-97\\y=107$

Hence , remaining two observation becomes 97 and 107.
