Answer:
I think its 600
Step-by-step explanation:
Because each minute diego types 40 words
So that means that 15 x40= 600
1. Factor P (x) = x^4 - 4x^3 + 3x^2:
1a. Factor out the GCF or x^2:
P (x) = x^2 (x^2- 4x + 3)
1b. Factor the trinomial. What multiplies to make 3 and adds to make -4?
(-1)+(-3) = -4 and (-1)(-3) = 3
P (x) = x^2 (x-1) (x-3)
2. Find the zeros be setting each factor equal to 0:
x^2 = 0 if x=0, with multiplicity 2
x-1 = 0 if x=1
x-3 = 0 if x=3
Your zeros are 0, 0, 1, and 3.
Step-by-step explanation:
the volume of the bucket is
15,000 = 1.5 × 10⁴ ml
the trough holds
2.7 × 10⁵ ml
by calculating how often the volume of the bucket fits into the volume of the trough, we will know how many buckets of water are needed :
2.7 × 10⁵ / (1.5 × 10⁴) = 2.7/1.5 × 10⁵/10⁴ = 2.7/1.5 × 10¹ =
= 27/1.5 = 18
the rancher needs 18 buckets of water to fill the trough.
Answer:
Step-by-step explanation:
From the attached photo
mean = 15.76
Standard deviation = 1.66
c) We want to determine a 90% confidence interval for the mean growth of pea plants
For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
15.76 ± 1.645 × 1.66/√7
= 15.76 ± 1.645 × 0.63
= 15.76 ± 1.04
The lower end of the confidence interval is 15.76 - 1.04 =14.72
The upper end of the confidence interval is 15.76 + 1.04 =16.8
