Answer:
domain is -6x I believe
Step-by-step explanation:
n/a
Answer:
6
Step-by-step explanation:
This is calculated as using z score
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Hence,
We find the z score of 95.44% confidence interval
95.44% = 1.9991
Hence.
1.9991 = ( X = 22) - (X = 10)
1.9991 = (22 - 16/ σ) - (10 - 16/ σ)
1.9991 = (6/σ - (-6/σ)
1.9991 = ( 6/σ + 6/σ)
1.9991 = (6 + 6/σ)
1.9991 = 12/σ
Cross Multiply
= 1.9991 × σ = 12
σ = 12/1.9991
= 6.00270121555
Approximately 6
Hence, the standard deviation is 6
Answer:
look below
Step-by-step explanation:
1. 1/45
2. 4/45
3. 1/15
4. 1/30
Step-by-step explanation:
a)
z = (140 - 118)/16 = 22/16 = 11/8 = 1.375 ≈ 1.38
in the z-table this gives us the p-value : 0.91621
that is the probability of values 140 and below.
for above 140 we need to calculate the value of the other side of the bell-curve :
1 - 0.91621 = 0.08379
b)
z = (90 - 118)/16 = -28/16 = -7/4 = -1.75
in the z-table this gives us the p-value : 0.04006
that is the probability of values of 90 and below.
Answer:
( x + 3 )( x - 7 ) and ( x + 1 )( x - 2 )
Step-by-step explanation:
Both of these represent <u>2 terms x 2 terms,</u> so that means they are both in factored form.
Example:
