Answer:
21 decigrams
Step-by-step explanation:
we know that
To find out the weight of each krill, divide the total weight of the krill by the number of krill
Remember that
To divide two numbers in scientific notation, divide their coefficients and subtract their exponents
Complete Question

Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is
The mean is
The standard deviation is
Generally the standard error of this measurement is mathematically represented as
substituting values
ppb
Now the probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb represented as P(X < 15 )
Next is to find the z value
Now checking the z-table for the z-score of -1 we have
Answer:
Yes
Step-by-step explanation:
Congruent means equal in size and they both are 84 cm therefore they are congruent
Answer:
a. 38.19m/s
b. 38.605m/s
c. 38.937m/s
d. 39.0117m/s
e. 39.01917m/s
Step-by-step explanation:
The average velocity is defined as the relationship between the displacement that a body made and the total time it took to perform it. Mathematically is given by the next formula:
Where:
a. Let's find h(3) and h(4) using the data provided by the problem:
The average velocity over the interval [3, 4] is :
b. Let's find h(3.5) using the data provided by the problem:
The average velocity over the interval [3, 3.5] is :
c. Let's find h(3.1) using the data provided by the problem:
The average velocity over the interval [3, 3.1] is :
d. Let's find h(3.01) using the data provided by the problem:
The average velocity over the interval [3, 3.01] is :
e. Let's find h(3.001) using the data provided by the problem:
