Answer:
y = 10
x = 64
Step-by-step explanation:
the equations containing y are adjacent angles in a parallelogram, meaning that they are supplementary, so we can create an equation:
5y + 2 + 12y + 8 = 180
solve this to get y = 10
the equation for x would be 2x + 5y + 8 = 180 because these angles are also supplementary
solve this to get x = 64
This problem represents "binomial probability," because any given "experiment" can have only two possible outcomes: defective or not defective.
Here the "population" probability that a given microwave unit is defective is 0.015. We arbitrarily define "defective microwave" as a "success" and "non-defective microwave" as a "failure."
We can obtain binomial probability values from a calculator such as the TI-83, from a table or from the binomial probabilty formula. In all of these cases the number of samples is given and is n=20; the probability of "success" is also given and is p=0.015.
Case 1: What is the probability that exactly 1 microwave unit is defective?
Using the TI-83: binompdf(20,0.015,1) = 0.225, or 9/40.
Case 2: What is the p. that at most 2 are defective? Add together the binomial probabilities binompdf(20,0.015,0),binompdf(20,0.015,1),binompdf(20,0.015,2).
Result: 0.7391 + 0.2250 + 0.0326 = 0.9967.
Mean: The mean of a binomial probability such as this one is simply np, which in his case is 20(0.015)=0.30. Find and apply the formula for the standard deviation.
Answer:
Steps to Construct a Perpendicular Bisector of line segment are as follows:
Step 1 : Draw the line segment of given
length or any length.
Step 2 : With W as center, using compass, draw a circle ( or two
arcs one above line and one below line ) . The radius of
circle ( or arcs ) should be more than half the length of
.
Step 3 : With the same radius and with X as center, draw
another circle (or arcs) using compass. Let it cut the
previous circle (or arcs) at A and B.
Step 4 : Join . It cuts at O.
Therefore, is perpendicular bisector of
Answer:
120 minutes
Step-by-step explanation:
Jelisa walked 6 miles in 90 minutes
The amount of mile walked in 1 minutes is
= 6/90
= 0.0666666
If she walks 0.066666 miles in 1 minute then in for 8 miles she travels
= 8/0.066666
= 120 minutes
