Kyle put "two" rectangles together to make this shape, so cut the shape into two. Then we know the bottom of one of the rectangles which is 16 is subtracted by 8 because half of 16 is 8 and 8 is one the measurements.
<span>$16,000 / (100% - 20%) = $16,000 / .8 = $20,000
to verify, work the answer backwards.
$20,000 - $20,000 * 20% = $20,000 - $4,000 = $16,000

Answer:
The probability is 0.9938
Step-by-step explanation:
In this question, we are asked to calculate the probability that the mean blood pressure readings of a group of people is less than a certain reading.
To calculate this, we use the z score.
Mathematically;
z = (mean - value)/(standard deviation/√N)
From the question, we can identify that the mean is 125, the value is 123 , the standard deviation is 9.6 and N ( total population is 144)
Let’s plug these values;
z = (125-123)/(9.6/√144) = 2.5
Now we proceed to calculate the probability with a s score less than 2.5 using statistical tables
P(z<2.5) = 0.9938
28 cans of soda into 2 groups in which the ratio is 3:4
3 x 4 = 12
4 x 4 = 16
12 + 16 = 28
you will put 12 cans in one group and 16 cans in another group
hope this helps
