A cryptarithm is a math puzzle in which the digits in a simple equation are replaced with letters. Each digit is represented by only one letter, and each letter represents a different digit. So, for example, we might represent 51+50 = 101 as AB + AC = BCB. In the cryptarithm SEND + MORE = MONEY, what digit does the letter Y represent?
There are 15,958,866 adults in a region. If a polling organization randomly selects 1235 adults without replacement, are the selections independent or dependent? If the selections are dependent, can they be treated as independent for the purposes of calculations? Are the selections independent or dependent?

So, vertical stretching of F(x) by a factor of 7 will be equal to 7 F(x).
Thus,
G(x) = 7 F(x)
G(x) = 7x²

Answer: Z = 107 as the opposite angles are equal. Then to find x, z is on the same line as (10x+3) so,
107+10x+3=180°
10x+3= 180-107
10x+3= 73°
now,
10x= 73-3 = 70
x= 70/10
x= 7
Hence z= 107 and x=7

Answer:
Step-by-step explanation:
First we can solve for x,
107 and 10x+3 is straight line which is 180 so make an equation:
10(7) + 3 = 73
{CHECK: 107 + 10(7) + 3 = 180}
Now, let's find the value of z
As we have the value of x it will be easy to find z by forming an equation:
{CHECK: 107 + 73 = 180}

Hello!
The variable of interest is
X: mark obtained in an aptitude test by a candidate.
This variable has a mean μ= 128.5 and standard deviation σ= 8.2
You have the data of three scores extracted from the pool of aptitude tests taken.
148, 102, 152
The average is calculated as X[bar]= Σx/n= (148+102+152)/3= 134
An outlier is an observation that is significantly distant from the rest of the data set. They usually represent experimental errors (such as a measurement) or atypical observations. Some statistical measurements, such as the sample mean, are severely affected by this type of values and their presence tends to cause misleading results on a statistical analysis.
Using the mean and the standard deviation, an outlier is any value that is three standard deviations away from the mean: μ±3σ
Using the population values you can calculate the limits that classify an observed value as outlier:
μ±3σ
128.5±3*8.2
(103.9; 153.1)
This means that any value below 103.9 and above 153.1 can be considered an outlier.
For this example, there is only one outlier, that this the extracted score 102
I hope this helps!
