Answer:
x is a solution
Step-by-step explanation:
X+14>5
Subtract 14 from each side
X+14-14>5-14
x > -9
Substitute the value in
6 >-9
This is true so x is a solution
Answer:
The answer is 1
Step-by-step explanation:
Mean
22+8+10+18+12+20 = 90
90/6=15
Median
22,8,10,18, 12,20
10+18 = 28
28/2= 14
Difference is 15-14 so the answer is 1
Answer:
0.00621
Step-by-step explanation:
We solve the above question using the
Z score formula. This is given as:
z = (x-μ)/σ/√n
where
x is the raw score = 12.20 or earlier
This means x ≤ 12.20
μ is the population mean = 13.20
σ is the population standard deviation = 2
n is the random number of samples = 25
z = 12.2 - 13.2/2/√25
z = -1/2/5
z = -1/0.4
z = -2.5
Probability value from Z-Table:
P(x≤ 12.2) = 0.0062097
Approximately = 0.00621
Therefore, the probability of randomly selecting a sample of 25 children who stood on their own by the average age of 12.2 months or earlier is 0.00621
Answer:
v = 7
Step-by-step explanation:
1. start with the equation
20 = 2v + 6
2. subtract 6 from both sides
14 = 2v
2. divide both sides by 2
7 = v
16.53 i think sorry if that’s not it
