Step-by-step explanation:
this is an arithmetic sequence :
a1 = 1
an = an-1 + 2 = a1 + (n-1)×2
the sum of n terms of an arithmetic sequence is
S = n×(a1 + an)/2
n = 5000
an = a1 + 4999×2 = 9999
S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000
24 bc if u add all them up and divide by 6 cus it’s 6 #s you’ll get 24
Using the normal distribution, we have that:
a) The sketch of the situation is given at the end of this answer.
b) The probability is:
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It 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, which is the percentile of X.
In this problem:
- Mean of 4.1 years, thus
. - Standard deviation of 1.3 years, thus
.
Item a:
The part between 2.8 and 7 years is shaded on the sketch given at the end of this answer.
Item b:
The probability is the <u>p-value of Z when X = 7 subtracted by the p-value of Z when X = 2.8</u>, thus:
X = 7:
has a p-value of 0.9871.
X = 2.8:
has a p-value of 0.1587.
0.9871 - 0.1587 = 0.8284, thus:

<h3>What is quantitative data?</h3>
Data that expresses a definite quantity, amount, or range is known as quantitative data. In most cases, the data is accompanied with measuring units, such as metres in the case of a person's height. Setting boundaries for such data makes sense, and performing mathematical operations on the data has significance.
Types of Quantitative Data are-
- Counter: A measure of entities. For instance, the quantity of users who have downloaded a specific app from the App Store.
- Measurement of physical objects: Calculating the dimensions of any physical object is called measurement. The HR executive, for instance, meticulously measures the size of each cubicle given to the new hires.
- Sensory calculation: Mechanism to automatically "sense" the parameters being monitored in order to generate a continuous source of data. A digital camera, for instance, transforms electromagnetic signals into a string of numerical data.
- Data projection: Algorithms and other mathematical analysis techniques can be used to project future data. For instance, after conducting a thorough investigation, a marketer will forecast a rise in sales following the introduction of a new product.
