Answer:
0.96592 or 0.97
Step-by-step explanation:
Answer:
b. 2.28%.
Step-by-step explanation:
Mean temperatue (μ) = 1000°F
Standard Deviation (σ) = 50
°F
For any temperature value, X, the z-score is given by:
For X= 900°F
A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:
<span>If the intial count was 100,000 bacteria, after one hour 90% decrease => 10 % stands => 100,000*0.1 bacetria. After two hours 90% decrease => 10% stands => 100,000*0.1^2. After three hours, they stand 100,000 * 0.1^3. After four hours, 100,000*0.1^4 and after five hours 100,000*0.1^5 = 1 bacteria. Answer: 1 bacteria. If the inital count is different you just have to muliply the inicial count time (0.1^n) to get the number of bacteria after n hours, and if the number of hours is 5, then the factor is (0.1^5). </span>
Answer:
6x+10 ≥ 4x-4
Step-by-step explanation:
Answer:
$180
Step-by-step explanation:
1. Find the perimeter: 2w + 2L
2(4) = 8 + 2(5) = 10
8 + 10 = 18 feet of fencing
2. multiply the cost per foot (10) by the number of feet (18)
10*18 = 180
