Barbara claims that her horse can do simple addition problems. She showed her horse 8 different cards with simple addition probl

Nataliya [291]

Answer:

"Yes, the chances of getting 8 correct when guessing are very low"

Step-by-step explanation:

The point diagrams show us how likely is the occurrence of an event. When casting 8 coins there is a chance to get between 1 and 8 tails.

The dot plot tells us how many times 1, 2, 3, 4, 5, 6, 7 or 8 tails were obtained. When the number of trials increases, then the value with the most points in the diagram represents the number of queues most likely to be obtained, and the value with fewer points represents the least probable number of queues that can be obtained by casting 8 times a coin .

The dot plot for the experiment shows that it is very unlikely to get 8 queues when casting 8 coins. Of 53 times, this only happened once.

Just as it is unlikely to get 8 tails when throwing 8 coins, it is also unlikely that a horse guesses the 8 correct answers of the 8 simple sum problems. Then, the horse of barbara maybe did not guess the 8 answers.

Therefore the correct answer is option A:

"Yes, the chances of getting 8 correct when guessing are very low"

The number of employees for a certain company has been decreasing each year by 3%. If the company currently has 810 employees an

8090 [49]

Answer:

219 employees

Step-by-step explanation:

3% of decreasing rate of employees per year is calculated thus:

$3\% \: of \: 810 \: employees$

$= \frac{3}{100} \times 810$

$= 24.3 \: employees \: per \: year$

In 9 years,

$= 24.3 \times 9$

$= 218.7 = 219 \: employees$

Therefore, the number of employees for a certain company where decreasing rate of employees is 3% and continued to decrease for 9 years; and 810 employees are currently working is 219 employees. By implication, 810 + 219 = 1029 employees were working in the company 9 years ago.
