1 answer:
Zigmanuir [339]3 years ago

The beginning part of the question is missing and it says;

The measures of center can be used to summarize the number of pets that students own. Cameron asked eight of his classmates how many pets they own. The results are listed below.

1, 0, 2, 0, 3, 7, 0, 2, 4

Answer:

Median

Step-by-step explanation:

Let's rearrange the results from least to most.

0, 0, 0, 1, 2, 2, 3, 4, 7

Mode is the most occurring number which in this case is zero, so Cameron can't use that to convince his parents to get another pet.

Median is middle number and in this case is 2.

Mean is; sum of results/ number of results = 19/9 = 2.11

Thus, the best measure of tendency for Cameron to use is median.

Given cos ⁡ ( θ ) = 5/6 , then sin ⁡ ( θ ) = a/b .<br><br> Determine the values of a and b.
slega [8]

Answer:

a = √11 and b = 6

Step-by-step explanation:

Refer to attached picture for reference

for an right triangle with angle θ

we are given

cos θ = 5/6 = length of adjacent side / length of hypotenuse

hence

adjacent length = 5 units

hypotenuse length = 6 units

the missing side is the "opposite" length which we can find with the Pythagorean equation. in our case:

hypotenuse ² = adjacent ² + opposite²   (rearrange)

opposite ² = hypotenuse ² - adjacent ²

opposite ² = 6² - 5²

opposite = √ (6²-5²) = √11

sin θ = opposite length / hypotenuse  (substitute values above)

sin θ = √11 / 6

hence a = √11 and b = 6

What is the value of 13.997x4 to 2 decimal places ?
VARVARA [1.3K]

Answer:

Hence the answer to 2 decimal places becomes 55.99

Step-by-step explanation:

SOLUTION

We want to solve:

13.997×4 to 2 decimal places

Now:

13.997×4=55.988

Now, 55.988 to decimal places, after the decimal point, we count the first two numbers, which are 9 and then 8. Then check the number after the 8, is it up to 5? Yes, it is, because it is 8. Now change the 8 to 1 and add it to that second number after the decimal point, this gives nine.

Hence the answer to 2 decimal places becomes 55.99
