Answer:
Step-by-step explanation:
So you got (4x-15) and x
We know it will equal 180 total so you will do
(4x-15)+x=180
Add 15 to each side
4x+x=195
5x=195
Divide each side by 5
x=39
So if X equals 39, your only possible answer is A
Answer:
w < 13
Step-by-step explanation:
variable: w
Inequality: 8 + 2w < 34
Solution: 2w < 26
w < 13
Answer:
Inter quartile range.
Step-by-step explanation:
We have been given that the amount of money that college students spend on rent each month is usually between $300 and $600. However, there are a few students who spend $1,300.
We know that range, interquartile range, variance and standard deviation are the measures of spread.
Since $1300 is large valued outlier as mostly students spend between $300 and $600, so mean of our given data set will be grater than median and our given data is skewed to right.
Since range, variance and standard deviation are not good measure of spread for skewed data, therefore, inter-quartile range would be the most appropriate to measure the amount of money that college students spend on rent per month.
I'm amusing it's 100,000,000 i don't know if I'm right or wrong
Answer:
1/24
Step-by-step explanation:
To start, we can calculate the probability of each individual event:
<u>Getting the person right:</u>
1/2
<u>Getting the weapon right:</u>
1/3
<u>Getting the room right:</u>
1/4
Here, you're trying to find the probability of the intersection of the three events. This means we must multiply the probabilities of the independent events together.
1/2*1/3*1/4=1/24
or
0.0417
Note that we multiply the probabilities together when the previous event doesn't affect the probability of the next event. In general, questions that ask for the probability of a happening and b happening mean you multiply the probability of a and b (events that satisfy your demands are decreasing because you need BOTH events to occur).
On the other hand, questions that ask for the probability of a or b happening, meaning the events that satisfy your demands will increase (2 options versus 1), so you'd add the probabilities of a and b happening.
Hope that makes sense, let me know if you have any questions!
