Answer:
Man i also need this please everyone who knows answer thisssss
Step-by-step explanation:
PLEASE!
Since both the length and the width are tripled, the area will be nine times larger. To counter this, divide by nine. 108/9=12 Divide this by 2 to get one length and one width. You get 6. 1+5=6 and 1 is 4 smaller than 5, so the width of this rectangle is 1 cm and the length is 5 cm.
Yes you would get the bonus because 25/40 would equal to 62.5%
Answer:
im guessing 6 is your base and your height is 15 3/4.
Formula of a triangle we must remember:
BH x 1/2 (basically dividing by 2)
94.5 (fraction form will be: 94 1/2)
94.5 divided by 2 = 47.25 <---------- decimal form
94 1/2 divided by 2 = 47 1/4 <------- fraction form
The probability of finding a substandard weld is: p = 5% =
0.05 <span>
We are given that the sample size: n = 300
Using the Poisson Distribution , the average number of welds (m) is:</span>
m = n*p =
m = 300 * 0.05 <span>
m =15 </span>
<span>
The standard deviation of welds (s) is calculated by:</span>
s = sqrt (m)
s = sqrt (15)
s = 3.873
<span>
<span>Assuming normal distribution, the z value corresponding to 30
sub standards is:
z =( X - Mean) / standard deviation
z =(30 - 15) / 3.873
z = 15 / 3.873
z = 3.87</span></span>
<span>
<span>The z value based on the standard normal curves has a maximum
value of 3.49. Beyond that z value of 3.49 would mean exceeding 100%. Therefore
z = 3.87 is not normal and definitely it is unusual to find 30 or more
substandard.</span></span>
