Answer: About 12 of those 60 students are boys.
To find the percent, you'll convert 20% to a decimal.
20 / 100 = 0.2
Then, multiply 60 by 0.2
0.2 × 20 = 12
That's one way, another way is:
Convert 20% to a fraction.
20% = 1/5
Then multiply 60 by 1/5.
60 × 1/5 = 60/5
Lastly, divide 60 by 5
60 / 5 = 12.
Hence, 12 is the answer.

If you were born in 1925 you would be 42 years old in 1967
1967 - 1925 = 42
Answer:
A, B, C, D
Step-by-step explanation:
(A) Checking the Equal Variance Assumption, the appropriate technique to use is:
- The ANOVA (Analysis of Variance) F test
- Plot residuals against fitted values
(B) Checking the Normal Assumption, the appropriate techniques to use are:
- Test for Kurtosis & Skewness
- Kolmogorov-Smirnov Test
- Q-Q Plots (the graphical method) also known as Quantile Plot
- Do not use a histogram; it is not advisable
(C) Checking for Model Misspecification, the appropriate techniques to use are:
- The Ramsey Regression Specification Error Test; also called RESET
- The Davidson & MacKinnon J. Test
(D) Checking for dependent errors, the appropriate technique to use is:
- Plot residuals against time variables
Actually Welcome to the Concept of the circles.
It's is universally proven that ratio of circumference and diameter is always π
hence the decimal value is π = 3.14
===> answer is option B.) 3.14
Answer:
d) x = 72°
Step-by-step explanation:
Corresponding Angles: The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.
These angles are EQUAL to each other.
Now, here in the given figure:
The two below lines are parallel to each other.
Also, the line crossing it on the right side forms a traversal.
So angle x and angle with 72 degrees form a pair of Corresponding Angles.
⇒ x = 72°
Hence the measure of angle x = 72°
