Do 4 1/4 - 1/4 which is easy, just take away the 1/4 and you get 4, so he used 1/4 gallons
The answer is 200. 1% is equal to 2, so 100% is equal to 200.
Answer:
Two parallel lines
Step-by-step explanation:
the slopes are the same: slope = 3
f(x) 3x + 5 g(x) = 3x - 2
Pick at least three x values and find their corresponding values for y. Remember the f(x) and g(x) represent y
f(x) = 3x + 5 g(x) = 3x - 2
y = 3x + 5 y = 3x - 2
let x = 0 y = 3(0) + 5 y = 3(0) - 2
y = 5 y = -2
Ordered pair (0, 5) (0, -2)
Let x = 1 y = 3(1) +5 y = 3(1) - 2
y = 8 y = 1
ordered pair (1, 8) (1, 1)
Let x = -1 y = 3(-1) + 5 y = 3(-1) - 2
y = 2 y = -5
ordered pair (-1, 2) ( -1, -5)
Locate the ordered pairs and draw the graph on the lines.
you will graph two parallel lines
Answer:
[ 21.79, 33.0 ]
Step-by-step explanation:
Given:
Sample size, n = 7
Sample mean, μ = 27.4
Standard deviation, σ = 5.75
Confidence level is 99%
also, population is normal i.e normally distributed
Thus,
Confidence interval = μ ± 
For confidence level of 99%
z-value = 2.58
Therefore,
Lower limit of Confidence interval = μ - 
or
Lower limit of Confidence interval = 27.4 - 
or
Lower limit of Confidence interval = 21.79
Upper limit of Confidence interval = μ + 
or
Upper limit of Confidence interval = 27.4 + 
or
Upper limit of Confidence interval = 33.00
Hence, confidence interval = [ 21.79, 33.0 ]
