2.75%= convert it to a decimal
.0275
Now, multiply that by 20.
20*.0275= 0.55
0.55 is 2.75% of 20.
I hope this helps!

Probability of orange: 7/22
^ That's for one draw.
For 2 draws, it's when he draws an orange on one <u>and</u> then an orange on the next. So
7/22 x 7/22 = 49/484
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
Answer:
x = -9
Step-by-step explanation:
6x - 27 = 3x - 54
solve for x
subtract 3x from each side then add 27 to each side. lastly you should get
3x=-27
Divide both sides by 3 to get -9
By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.
The Central Limit Theorem established that, for a normally distributed random variable X, with mean and standard deviation, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation ;
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
The sample of 112 residents has a mean GPA of 1.7.
By the Central Limit Theorem, the best point estimate for the mean GPA for all residents of the local apartment complex is 1.7.
