The height of a parallelogram is 4 times the base. The base measures 3 1/2 ft find the area off the parallelogram

Mathematics

Answer:

Area = 49 ft²

Step-by-step explanation:

The formula for area of a parallelogram is A = bh, where b is the base, and h is the height.  Here, the base is given and the height is 4 times the length of the base

Here b = 3 1/2, and h = 4(3 1/2) = 14      

             3 1/2 becomes 7/2 as an improper fraction,  4(7/2) = 28/2 = 14

So the area is

A = 14(3 1/2)

A = 14(7/2)

A = 98/2

A = 49 ft²

Answer:

Step-by-step explanation:

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°

Suppose we take two different random samples from the same population of test scores. The population mean and standard deviation
Leto [7]

Answer:

The 95% confidence interval obtained with a sample size of 64 will give greater precision.            

Step-by-step explanation:

We are given the following in the question:

A 95% confidence interval is calculated with the following sample sizes

n_1 = 25\\n_2 = 64

The population mean and standard deviation are unknown.

Effect of sample size on confidence interval:

  • As the sample size increases the margin of error decreases.
  • As the margin of error decreases the width of the confidence level decreases.
  • Thus, with increased sample size the width of confidence level decreases.

If we want a confidence interval with greater precision that is smaller width, we have to choose the higher sample size.

Thus, the 95% confidence interval obtained with a sample size of 64 will give greater precision.

Find the greatest common factor of these three expressions.<br> 18x^2, 42x^4, and 30x^5
DanielleElmas [232]

Answer:I think the answer is 6x because

18= 6x3

42= 6x7

30= 6x5

Step-by-step explanation:

18= 6x3

42= 6x7

30= 6x5 And 6x(3x+7x^3+5x^4) it became 18x^2+42x^4+30x^5
