Ok so being in middle school I might not do this right but I will help the best I can.
I know that in order to subtract the two fractions you need to...
1/3 - 5/6
2/6 - 5/6 = 3/6 = 1/2
Ok so now we have
3/6 divided by 5/6
for dividing these things it is copy dot flip
3/6*6/5 = 3/5
This would then be 3/5
I am not positive if this is correct but going off of what I have learned I think it should be ok.
Answer:
1.4
Step-by-step explanation:
Given the expression 2.1/1.5.
This can also be expresses as;
2.1/1.5
= 21/10 ÷ 15/10
= 21/10 × 10/15
= 21/15
= 7/5
= 1.4
Hence the result is 1.4
Answer:
Skewed
Step-by-step explanation:
Looking at the options;
- Bimodal has to do with 2 modes in a symmetrical Distribution. Thus is doesn't apply to the mean.
-bell shaped deals with the graphical depiction of a normal probability distribution, whereby the underlying standard deviations from the mean will create the curved bell shape. So it is not used for mean.
- symmetric deals mirror images of the distribution when a vertical line is drawn down the middle of the distribution.
-skewed shape tells us whether the mean is pulled to the tail and if it is more than or less than the median.
- uniform shape means same frequency for each class.
Answer:
Step-by-step explanation:
4x+5y = 15
slope of line is -⅘
perpendicular to the line is 5/4
point-slope equation for line of slope 5/4 through (-4,-1):
y+1 = (5/4)(x+4)
