Answer:
X = 20.6 inches
Step-by-step explanation:
Pythagorean Theorem:
A = 41.2 in, while B = 35.7 in and we are solving for C.
Now solve for C
Take the square root
Answer:
Step-by-step explanation:
Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub...we r looking for b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
equation is : y = 3/4x + 19/4...lets put this in standard form
y = 3/4x + 19/4
-3/4x + y = 19/4...multiply by -4
3x - 4y = -19 <== standard form
if (x,5) is on the line
3x - 4y = -19.....sub in 5 for y
3x - 4(5) = -19
3x - 20 = -19
3x = -19 + 20
3x = 1
x = 1/3 <====so point a = (1/3,5)
Answer:
1.28
Step-by-step explanation:
Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.
(Two tailed test for testing sample proportion with population proportion)
Std error of proportion assuming p = 0.53 is
p difference = 0.02
Z= test statistic = p diff/std error = 1.2775~1.28
