Answer:
a.) x = 5.36
b.) y = - 0.001
c.) t = 11.26
d.) k = 4.57
Step-by-step explanation:
a) x−1.27=4.09
b) 2.3−y=2.301
c) t+3.04=14.3
d) 1.1+k=5.67
Solving. right?
a.) x = 4.09 + 1.27 = 5.36
b.) y = 2.3 - 2.301 = - 0.001
c.) t = 14.3 - 3.04 = 11.26
d.) k = 5.67 - 1.1 = 4.57
Answer:
5) 126
6) 116
Step-by-step explanation:
5) m∠NLM is equal to the arc MN, or 63x.
To find x, use the inscribed angle theorem.
32x − 1 = ½ (63x)
64x − 2 = 63x
x = 2
Therefore:
m∠NLM = 63(2)
m∠NLM = 126
6) Using the same logic:
9x + 4 = ½ (19x + 2)
18x + 8 = 19x + 2
x = 6
Therefore:
mYX = 19(6) + 2
mYX = 116
The mileage that the supervisor will achieve that is within a z-score of 1.5 is; 23.6
<h3>How to find the z-score? </h3>
Formula for z-score in statistics is;
z = (x' - μ)/s
Where;
x' is sample mean
μ is population mean
s is sample standard deviation
We are given;
x' = 29
Standard deviation; s = 3.6
z = 1.5
Thus;
1.5 = (29 - μ)/3.6
μ = 29 - (1.5 × 3.6)
μ = 23.6

18m/3hrs = 6m/hr
Multiply the rate by the time:
(6m/hr)(3/4hr)
6 time 3/4 gives you 4.5, or 9/2; the hours cancel, leaving you with:
4.5 miles, or as a fraction 9/2 miles, or, as a mixed number, 4 1/2 miles. (whichever way they want it.)
Hope this helps!
