Answer:
4
Step-by-step explanation:
First we need to find the total area of the garden so we can see how many bags she will need. The area of a rectangle is its length multiplied by its width, so the area of her garden is 12 (the length) x 10 (the width). 12 x 10 = 120 square feet. If each bag covers 30 square feet, then she will need 120/30 = 4.
4 bags of fertilizer to cover the 120 square feet of the garden area.
Hope this helped!
Answer:
We found the factors and prime factorization of 42 and 63. The biggest common factor number is the GCF number. So the greatest common factor 42 and 63 is 21.
Step-by-step explanation:
$1,675 and variable costs per plant are $3.65. What is the maximum profit Rebecca Clarke's
will make if it sells all the plants at the discounted price?
Answer:
$1,540.70
Step-by-step explanation:
1675/335 = 5
3.65 * 335 = 1222.75
Cost of $8.65 per plant, or $2,897.75 for every plant.
12.99 - 8.65 = 4.34
Profit of $4.34 per plant, or $1,540.70 total.
Answer:
At least 75% of healthy adults have body temperatures within 2 standard deviations of 98.28degreesF.
The minimum possible body temperature that is within 2 standard deviation of the mean is 97.02F and the maximum possible body temperature that is within 2 standard deviations of the mean is 99.54F.
Step-by-step explanation:
Chebyshev's theorem states that, for a normally distributed(bell-shaped )variable:
75% of the measures are within 2 standard deviations of the mean
89% of the measures are within 3 standard deviations of the mean.
Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean?
At least 75% of healthy adults have body temperatures within 2 standard deviations of 98.28degreesF.
Range:
Mean: 98.28
Standard deviation: 0.63
Minimum = 98.28 - 2*0.63 = 97.02F
Maximum = 98.28 + 2*0.63 = 99.54F
The minimum possible body temperature that is within 2 standard deviation of the mean is 97.02F and the maximum possible body temperature that is within 2 standard deviations of the mean is 99.54F.
