Answer: the answer is 3
Step-by-step explanation:
because the leaf is the ones place so all you need to do is count the amount of 5's in each stem
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
Answer:
Step-by-step explanation:
Tthe population is normally distributed and the sample size is .
Since the population standard deviation is unknown and the sample standard deviation , must replace it, the t distribution must be used for the confidence interval.
Hence with degrees of freedom of 21, .(Read from the t distribution table)
The 98% confidence interval can be constructed using the formula:
.
From the question the sample mean is dollars and the sample standard deviation is dollars.
We substitute the values into the formula to get
Therefore, we can be 98% confident that the population mean is between is between 19.22 and 44.78 dollars.
Answer:
As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,
'800+900×25-65(89-5)-12÷67-7'
Solving the bracket gives us:
'800+900×25-65(84)-12÷67-7'
Now avoiding the Bracket:
'800+900×25-5460-12÷67-7'
Now first we have to do MUltiplication, so we will get,
'800+22500-5460-12÷67-7'
Now let's do the division, so we will get,
'800+22500-5460-0.17-7'
Now lets do the additions and subtractions we will get,
