Answer:
The quadrilaterals which have opposite angles congruent are parallelograms.
Hope it will help :)
Z score ( X = 1890 ): 1.31
Z score ( X = 1230 ): -0.76
Z score ( X = 2220 ): 2.34 (This value of Z is unusual )
Z score ( X = 1360 ): -0.35
<u>Step-by-step explanation:</u>
Here we have , A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1473 and the standard deviation was 318 . The test scores of four students selected at random are 1890 , 1230 , 2220 , and 1360 . We need to find Find the z-scores that correspond to each value and determine whether any of the values are unusual. Let's find out:
We know that Z score is given by : ( data - Mean ) / ( standard deviation )
Z score ( X = 1890 ):
⇒
Z score ( X = 1230 ):
⇒
Z score ( X = 2220 ):
⇒
This value of Z is unusual as Value lies as : .
Z score ( X = 1360 ):
⇒
Let us first bring the equation given into the slope-intercept form.
We see that the above equation has slope 3/ 5, and therefore, the equation that we want to construct must also have this slope. Hence, we already know that the equation we are seeking must take the form
where b is the y-intercept yet unknown.
Let us plug in (x, y) = (8, -4) in the above equation, this gives
Hence, the equation of the line in slope-intercept form is
Answer:
y=6x-6
Step-by-step explanation:
The slope equation is: y=mx+b
Keep in mind that m= slope and b= y-intercept
Since this problem gives us both of the things needed to complete the equation, we just need to plug it in.
m, (slope) = 6
b, (y-intercept) = -9
y= 6x-6
I did it but I cant upload the image ...
the answer is 5x + 3 remainder 8
Edited: Ok, managed to upload it now.
