X^2+5x-3
At x=-6
(-6)^2 +5(-6) -3
36 -30 -3
36 -33
The answer is 3
Answer:
<h2>1/11</h2>
Step-by-step explanation:
even #s between (or including) 1 and 12:
2, 4, 6, 8, 10, 12
there are 6
6/12 for the first one
5/11 for the second one (one even # less)
4/10 for the third one
To find the probability of picking three even numbers from 1 to 12 in a row three times:
multiply the probabilities together:
(6/12)*(5/11)*(4/10)=(24/120)*(5/11)=(12/60)*(5/11)=(1/5)*(5/11)=5/55=1/11
The sum of the interior angles of a triangle add up to 180 degrees. Make 98, 50, and x add up to 180 in an equation.
98 + 50 + x = 180, add 98 and 50.
148 + x = 180, subtract 148 from both sides.
x = 32
Answer:
0.0051 = 0.51% probability that the thickness is less than 3.0 mm
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 4.8 millimeters (mm) and a standard deviation of 0.7 mm.
This means that
(a) Probability that the the thickness is less than 3.0 mm
pvalue of Z when X = 3. So
has a pvalue of 0.0051
0.0051 = 0.51% probability that the thickness is less than 3.0 mm
