1 answer:
Damm [24]3 years ago
4 0

Answer:

d) 86.2 degrees

x = 86.20°

Attached is the image used in the question;

Step-by-step explanation:

Applying the law of cosine;

Cos C = (a² + b² - c²)/2ab

Where;

Angle C = x

c = 13 ft

b = 9ft

a = 10ft

Substituting into the equation;

Cos x = (10² + 9² - 13²)/(2×10×9)

Cos x = 0.0667

x = cos⁻¹(0.0667)

x = 86.20°

Using unit concepts, it is found that:

  • a) Grams.
  • b) Grams.
  • c) Grams squared.
  • d) Grams squared.

-----------------------------

  • For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
  • The variance has the unit squared, both for the sample and the population.
  • For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.

-----------------------------

In this question, the data-set is in grams.

  • The standard deviation, both for the sample and the population, in items a and b, will be in grams.
  • The variance, both for the sample and the population, in items c and d, will be in grams squared.

The student council had six fund raisers during the school year. They raised $212, $205, $206, $190, $188, and $195. Using the c
Rus_ich [418]

Answer:

$1200

Step-by-step explanation:

The clustering method for estimation is a method used for estimating the sums and products of numbers. This method is used when the numbers that are to be multiplied or added are near in value to a single number.

Given the money raised by six fund raisers:

$212, $205, $206, $190, $188, and $195

The numbers are to be added to find the total money raised. i.e.:

$212 + $205 + $206 + $190 + $188 + $195

But all the numbers are close to $200. Hence:

Using clustering method = $200 + $200 + $200 + $200 + $200 + $200 = 6 * $200 = $1200
