It would end up being 4/5 if you brought it to the lowest tern.
Answer:
1.3 meters per sec
Step-by-step explanation:
7.8/6=1.3
hope this helps :3
if it did pls mark brainliest ^^
Answer:
13/50 is the simpilist form of 26%
<h3>2, 6, 10</h3>
Step-by-step explanation:
Tom = s
Nancy = r
s=r-2 = Tom=Nancy-2
This means that Tom has $2 less than Nancy as they stayed in the information they gave us. They want us to complete the graph.
Since Tom has $2 less than Nancy all we have to do is apply rule -2 to each number.
4-2=2
8-2=6
12-2=10
Therefore the numbers to add to the graph are 2, 6, and 10.
Answer:
a) 0.0228
b) 94.6
Step-by-step explanation:
The formula for calculating a z-score when you are given a random.number of samples is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
n = random number of samples
Given a normal distribution with u = 75 and o = 40, if you select a sample of n = 16,
a) what is the probability that the sample mean is above 95? (4 d.p.) b)
= x = 95
Hence:
z = 95 - 75/40/√16
= 20/40/4
= 20/10
= 2
Probability value from Z-Table:
P(x<95) = 0.97725
P(x>95) = 1 - P(x<95) = 0.02275
The probability that the sample mean is above 95 to 4 decimal places = 0.0228
b) What is the value, of which there is 97.5% chance that a sample mean is less than that value?
97.5% chance = z score for the confidence interval = 1.96
Hence:
z = (x-μ)/σ/√n
1.96 = x - 75/40/√16
1.96 = x - 75/ 40/4
1.96 = x - 75/10
Cross Multiply
1.96 × 10 = x - 75
19.6 = x - 75
x = 19.6 + 75
x = 94.6
The value, of which there is 97.5% chance that a sample mean is less than that value is 94.6
