Answer:
15,643
Step-by-step explanation:
To find the population in a future year, use the formula:
where A is the amount, p is the starting population, r is 14% or 0.14, and t is the number of years after 2001.
Since the population is increasing it is addition. Here we are finding A, P =350, r=0.14, and t=29.
You can go 21 days without exceeding your budget.
$19 x 21 (21 representing the days) = $399
Then you take $399 and add $45
$399 + $45 = $444

Price of 12 pounds of trail mix = 12 x $4.20
= $50.40
Let the number of pounds of skittles and trail mix be x,
number of pounds of skittles = 12 - x
price of pounds of skittles = $16.70(12 - x)
= $200.40 - 16.7x
total amount = 10.93x
200.40 - 16.7x + 50.40 = 10.93x
250.80 = 27.63x
x = 10 (nearest whole number)
the minimum number of pounds of skittles is 10.
Answer:
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
Manufacturing Ball bearings are manufactured with a mean diameter of 5 millimeters (mm).
This means that
With a standard deviation of 0.02 mm.
This means that
(a) What proportion of ball bearings has a diameter more than 5.03 mm
This is 1 subtracted by the pvalue of Z when X = 5.03. So
has a pvalue of 0.9332
1 - 0.9332 = 0.0668
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
Mr Jones typed 40 * 10 = 400 words.
Mrs Gonzales took 400 / 50 = 8 minutes to type same number of words.
