Answer:
-3
Step-by-step explanation:
i just took the test
First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:
-15.5t + 3.1t = -13.44 + 10.56 - 13.24
Now combine the numbers on both sides of the equation and solve for t:
-12.4t = -16. 12
t = 1.3
Hope this helps!
2l + 2w = 132
l = 3w + 2
2(3w+2)+2w=132
6w + 4 + 2w = 132
8w + 4 = 132
8w = 128
w = 16
l = 3(16) + 2
l = 48 + 2
l = 50
2(50) + 2(16) __ 132
100 + 32 = 132
Answer:
6 and 8
Step-by-step explanation:
6+8=14 difference 2
A. we use the z statistic to solve this problem
z = (x – u) / s
We calculate the value of the sample mean u and standard deviation
s:
u = $30 * 304 = $9120
s = $21 * 304 = $6384
z = (9,600 – 9120) / 6384
z = 0.075
From the normal tables using right tailed test,
P = 0.47
B. At worst 11% means P = 0.11, so the z value at this is
z = -1.23
-1.23 = (x – 9120) / 6384
x = 1267.68
