Step-by-step explanation:
2x + 5 = I / 2 ×16
2x=3
x=3/2
Answer:
73.1 inches
Step-by-step explanation:
We solve for this using z score formula.
z-score is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
x = unknown = randomly selected male's height
μ = 70.3 inches
σ = 4.1 inches
z = is not given but we are given its percentile which is 75
The z score for a 75th percentile = 0.674
Hence,
0.674 = x - 70.3/4.1
Cross Multiply
0.674 × 4.1 = x - 70.3
2.7634 = x - 70.3
x = 70.3 + 2.7634
x = 73.0634 inches
The height of the randomly selected male = 73.0634
Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches
Okay so
65 has an inflammation of 2.8
65x2.8 = 182
90 has an inflammation of 1.5
90x1.5 = 140
so that means 45 has to have one of those
45x2.8 = 126
45x1.5 = 67.5
looking at the size differences it would make sense for the answer to be
126
hope this helps i haven't done math in a bit
The LCM is the smallest number that all of those numbers can divide into evenly. So the LCM of 3,9,12 is 1
The power of 25 on the variable z needs to be changed. It has to be divisible by 3.
