It's linear and equation of the function is :
f ( x ) = 2x - 1
The Floridians can predict to hear the thunder on about 183 days out of the 730 days.
<u>Step-by-step explanation:</u>
Given that,
- The total number of days = 730 days.
- The probability of hearing thunder on any day in Florida = 25%
Let 'x' be the number of days out of 730 days that Floridians will hear thunder.
<u>To find the number of days that Floridians will hear thunder :</u>
Number of days will hear thunder = 25% of Total days
The 25% can be expressed in the form of 25/100.
Therefore, the x days that Floridians will hear thunder is given as,
⇒ x = (25/100) × 730
Further simplifying the above equation,
⇒ x = 2.5 × 73
⇒ x = 182.5
Since the number next to the decimal point is equal to 5, round it to the nearest integer.
Therefore, the value of x is approximately equal to 183 days.
Thus the Floridians can predict to hear the thunder on about 183 days out of the 730 days.
Answer:
4/8 is steeper than 3/10
Step-by-step explanation:
4 is half of 8 and in decimal form is 0.5. 3/10 in decimal form is 0.3. Therefore 0.5 is greater than 0.3, so 4/8 is considered to be steeper than 3/10.
Answer:
-2.23 ; 0.012874
Step-by-step explanation:
Given that :
Population mean (μ) = 25 minutes
Same mean (x) = 24min 12 seconds = 24.2 minutes
Standard deviation σ = 3
Sample size (n) = 70
Test statistic :
Using the relation :
Tstatistic = (x - m) / σ/sqrt(n)
Tstatistic = (24.2 - 25) / (3/sqrt(70)
Tstatistic = - 0.8 / 0.3585685
Tstatistic = - 2.2310939
= - 2.23
The P value can be obtained using a. P value Calculator :
P at α = 95% and test statistic = - 2.23
Hence, p = 0.012874 using calculator
