Answer:
Women has better study habit than men.
Step-by-step explanation:
For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.
The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
Calculating all values:
= 141.0556
= 121.25
Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.
OK so on the top problem, the first thing you want to do is find the √37, once you know the answer to that you can compare it to 5 1/4 then it will be much easier to see is in fact √37 less than 5 1/4 or not.
On the bottom you want to know if 15 over the square root of ten is greater than 8.38 so what you want to do is to first find the square root of ten. after you know this then you put that number under 15. then you can compare what ever 15÷√10 is to 8.83. if you need any more info let me know.
Answer: magnesium >potassium hope it helps
Hi there!
First we need to calculate how much the 3 T-shirts cost and subtract that from the amount she paid to find the change.
First, we multiply to find the coats of the T-shirts.
3 × 8 = 24
Now, we subtract 24 from 50.
50 - 24 = 26
So, she got $26 of change.
Hope this helps!
step 1
convert pounds to ton
1 ton------> 2204.62 lb
<span>each crate weighs 80 pounds
so
by proportion
1/2204.62=x/80
x=80/2204.62-----> x=0.036 ton
each crate weighs 0.036 ton
step 2
divide 2 ton by 0.036
2/0.036=55.11 crate----------> 55 crate
the answer is
</span>the greatest number of crates that can be loaded onto the elevator is <span>55
alalternative method
</span>step 1
convert ton to pounds
1 ton------> 2204.62 lb
a freight elevator has a weight limit of 2 ton
2 *2204.62 -----> 4409.24 lb
step 2
each crate weighs 80 pounds
divide 4409.24 by 80
4409.24/80=55.11 crate----------> 55 crate
