Answer:
70
Step-by-step explanation:
First, put the values they gave you in order from least to greatest.
52 62, 72, 77
In order for the median to be 72, it has to be in the middle of the data set. Since there are 2 values on the left of 72, there must be 2 values on the right. The data set is also in order from least to greatest, so we know that the last value has to be over 72. Because it is placed to the right of 72. The only value of the options that isn't greater than 72 is 70.
Answer:
x = 9
Step-by-step explanation:
To solve these problems, you first set up an equation representing the information given.
6x = x² - 27
This turns into a quadratic equation which you need to factor out.
0 = x² - 6x - 27
You want to choose two numbers that multiply to -27, and add up to -6
0 = (x - 9)(x + 3)
If you're unfamiliar with factoring, you take the opposite sign of the number in the parentheses because it's a shortcut when setting it equal to 0.
x = 9, -3
Since it asks for the positive solution only, the answer is x = 9.
I hope this helps!
1. 7
2. 15
3. 0
4. 5
Hopefully this is right, basically you are just turning negatives into positives I think.
Answer: The experimental probability is 70 %
Step-by-step explanation:
According to the given question have to find that the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings
As we know that,
If 10th-grade student chosen at random has at least one, but no more than two, siblings
Therefore, there can be one or two siblings
Such that, the total number of such students
Now, number of favorable outcomes =28 and total number of students
Now,
%
Answer:
Its either 25% or 15% but i would go with 25 first
