116
Step-by-step explanation:
Answer: 2x-6
Step-by-step explanation: 1 Remove parentheses.
x-5+x-1x−5+x−1
2 Collect like terms.
(x+x)+(-5-1)(x+x)+(−5−1)
3 Simplify.
2x-62x−6
Let the two numbers be x and y.
The sum is 45, therefore
x + y = 45 (1)
The difference is 5, therefore
x - y = 5 (2)
Add equations (1) and (2).
x + y + (x - y) = 45 + 5
2x = 50
x = 25
From (1), obtain
25 + y = 45
y = 45 - 25 = 20
Answer: 20 and 25
Answer:
Exponential growth
Step-by-step explanation:
The graph of y=5(1.12^x) is positive and upward sloping.
<span>Given a mean = 1300 and a Ď = 200, we can calculate that the lower bound of 1000 is (1000 - 1300) / 200 = -1.5 standard deviations below the mean.
The upper bound is (1437 - 1300) / 200 = 0.685 standard deviations from the mean.
Using the cumulative distribution function, we can calculate that the probability a randomly chosen steer lies on the interval [1000, 1437] is CDF(0.685) - CDF(-1.5) = 0.68652083824480004
p = 0.6865</span>
