Answer:
The z-score is -1.6 and it is not significant .
Step-by-step explanation:
Given : Test score = 48.4
Mean = 66
Standard deviation = 11
To Find :Find the z-score corresponding to the given value and use the z-score to determine whether the value is significant.
Solution:
Formula : 
Substitute the values
So, the z-score is -1.6
Now we are given that Consider a score to be significant if its z-score is less than -2.00 or greater than 2.00.
Since -1.6>-2 and -1.6<2
So, It is not significant
Hence the z-score is -1.6 and it is not significant .
Explanation below, but in short, a fraction means to divide the top/left number by the bottom/right number. It means to divide 5 by 6.
5/6 = 0.83333333...
Why is this? This is because a fraction simply means to divide the numerator (the top/left number) by the denominator (bottom/right number). So 5 ÷ 6 = 0.83333333... in decimal form.
Answer:
Y=60x^(2)-32x+4
Step-by-step explanation:
Y=4(3x-1)(5x-1)
=(12x-4)(5x-1)
=60x^(2)-12x-20x+4
<u>Y=60x^(2)-32x+4</u>
Answer:51.14
Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360
2x+5+5x-3=360
7x+2=360
7x=358
x=51.14
