Answer:
The number is 6
Step-by-step explanation:
Given:
A number tripled and 6 is 24
To Find:
The Number = ?
Solution:
Let the number be x
The question states that the number is tripled. so lets multiply the number by 3, We get
3x
Then
3x + 6 = 24
On solving the equation we get
3x = 24 -6
3x = 18
x = 6
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Sample mean(x) = 23500
Sample standard deviation (sd) = 3900
Sample size (n) = 20
Population mean (m) = 20,000
Null hypothesis : m = 20000
H1: m > 20000
To obtain the z-score :
(population mean - sample mean) / (sample standard deviation /√sample size)
(x - m) / (sd/√n)
(23500 - 20000) / (3900 / √20)
3500 / (3900 /4.4721359)
3500 / 872.06651
= 4.0134
Get the P value to know if to reject or accept the null:
P(z > 4.0134) = 1 - P(z < 4.0134)
P(z < 4.0134) = 1
1 - P(z < 4.0134) = 1 - 1 =0
Since P value is < alpha, we reject the null.
Hence average is > 20000

Step-by-step explanation:
2 to the 100 power = 1.2676506002 × 10 to the 30 power.
Answer:
55%
Step-by-step explanation:
probability of something happening = p
probability of that thing not happening = 1 - P
45%= 45/100= 0.45
therefore, the probability of snow today = 0.45
therefore,
probability there will be no snow=1 - 0.45 = 0.55
probability there will be no snow= 0.55
convert 0.55 back to percentage= 0.55×100= 55%
probability there will be no snow= 55%
