Answer:
It will take 1 day.
Each women will make 17 blankets
Step-by-step explanation:
We can model the number of blankets of Susan and Ella as linear equations:
Susan: B = 8 + 9*t
Where B is the number of blankets and t is the time in days.
For Ella, we have:
B = 10 + 7*t
To find when they will have made the same number of blankets, we just need to equate the value of B from one equation to the value of B from the other, and then we find the value of t:
8 + 9*t = 10 + 7*t
2*t = 2
t = 1 day
After 1 day they will have made the same number of blankets.
This number of blankets is:
B = 8 + 9*1 = 8 + 9 = 17 blankets
Can you please take a better picture
Yes, it is a function because each input has only one output.
Hope it helps!
Answer:
B, C, A, B
Step-by-step explanation:
i. 60+ 10 +110 = 180 ( so it can be scalene)
ii. 60 +120 =180 ( they have to, to make a triangle)
iii. Obtuse is 90 degrees or more
iv. 90 +60+30=180 (so it can be)
Answer: 0.0386
Step-by-step explanation:
Given: The population of 400 tall women has a mean height of 179.832 cm and a standard deviation of 12.192 cm.
Let X be a random variable that represents the height of woman.
Sample size : n= 50
The probability that the mean for this sample group is above 182.88 will be :
Hence, Required probability = 0.0386
