Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that
29 days saw high winds
This means that
7 days saw both rain and high winds.
This means that
How many days saw either rain or high winds?
This is
Sp
40 days saw either rain or high winds
Answer:
<
Step-by-step explanation:
√7 ≈ 2.66
14/5 = 2.8
2.66 < 2.8
√7 < 14/5
Best of Luck!
Answer:
X=17
Step-by-step explanation:
7x-1+5x-23=180
12x-24=180
12x=204
x=17
Confidence interval is given by the formula
x ⁺/₋ z* ( σ/ (√n) )
Where:
x = the sample mean = 130
z* = the z-value for 90% confidence = 1.645
σ = standard deviaton = 7
n = sample size = 145
Substituting these values into the formula gives:
130 ⁺/₋
130 ⁺/₋ 0.956
So the interval is in between (130 - 0.956) and (130 + 0.956)
