Answer:
1. 60% (decrease by 40%)
3. 30% (decrease by 70%)
5. 250% (Increase by 150%)
7. 40% (Decrease by 60%)
9. 171.4% (increase 71.4%)
11. 152.6% (Increase by 52.6%)
Step-by-step explanation:
1. 20x = 11 = 0.55 rounds to 0.6 => 60%
3. 56 x = 14 = 0.25 rounds to 0.3 => 30%
5. 18x = 45 = 2.5 => 250%
7. 126x = 48 = 0.38 rounds to 0.4 => 40%
9. 42x = 72 = 1.714 => 171.4%
11. 95x = 145 = 1.526 => 152.6%
Answer:
Median
mean>median
Step-by-step explanation:
When the data is skewed to right the suitable average is median. Median is suitable because it is less effected by extreme values and thus locate the center of the distribution perfectly. Here the salaries of basket players are skewed to right and the best measure of central tendency to measure the center of distribution is median.
When the frequency distribution is rightly skewed then the relationship of mean and median is that mean is greater than median that is Mean>median.
Hence when the distribution is skewed to right the best choice to measure the center of distribution is median and when the data is skewed to right mean is greater than median.
Yes; they have the same side lengths and angles
Im assuming you just want to take out common multiples so,
30d+18 is also the same as 6(5d+3)
Answer:
The money Rachael plan to collect for the shelter is <u>$350</u>.
Step-by-step explanation:
Given:
Rachel is collecting donations for the local animal shelter.
So far she has collected $245, which is 70% of what she hopes to collect.

.
Amount she collected = $245.
Percentage of amount she collected = 70%.
Now, to get the amount Rachael plan to collect we put an equation:
⇒ 
⇒ 
⇒ 
<em>Dividing both sides by 0.70 we get:</em>
⇒ 
Therefore, the money Rachael plan to collect for the shelter is $350.
