Is it meaning the cereal is 25% off? If so then your answer would be $2.44
Answer:
a2 =14
a4 = 22
a11 = 50
Step-by-step explanation:
an = 10 + (n-1) *4
n is the term number
Let n =2
a2 = 10 +(2-1)*4 =10 +(1)*4 = 14
Let n =4
a4= 10 + (4-1)*4 = 10 *3*4 = 10+12 = 22
Let n = 11
a11 = 10 +(11-1)*4 = 10 *10*4 = 10+40 = 50
Answer:
test statistic is ≈ -0.36
p-value is ≈ 0.64
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
Step-by-step explanation:
a hypothesis test where H_0: mu = 235 and H_1:mu > 235
test statistic can be calculated as follows:
z=
where
- sample mean driving distance (233.8 yards)
- M is the average expected distance that the average golfer can hit the ball under null hypothesis. (235 yards)
- s is the standard deviation (46.6 yards)
- N is the sample size (192)
Then test statistic is z=
=-0.3568
p-value is 0.64 >0.05
There is no significant evidence that the average golfer can hit the ball more than 235 yards on average.
The first step to getting this in vertex form would be to put this in proper standard form. This is so that you can split the middle term which is a step of completing the square.
Answer:
3, 4, 7
Step-by-step explanation:
In order to solve inequalities, you want to isolate the variable.
Subtract 3 from both sides to give you (I can't put the greater than or less than or equal to with the line underneath, so just imagine that it's there)
-8 <-4r
Divide both sides by -4 to get the r by itself.
-8÷-4=2
2<r
Two is less than or equal to r, or you can word it r is greater than or equal to 2. So now you look at your options, and choose the ones that are greater than 2. 3, 4, and 7 are all greater than 2.
