Answer:
18.8
Step-by-step explanation:
Hey there!
In order to find the solution to this question, we need to find the circumference
To find the circumference, you need to take the diameter and multiply it by 3.14 which is pi
In this case, the diameter is 6
6 x 3.14 is 18.84 so this means that the circumference of the circle, or in this case, a cookie, is 18.84
Also, it says to round to the tenth so our final answer will be 18.8
So the answer to this question is 18.8
Answer:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
Step-by-step explanation:
We know that 354 students are between 100 and 130 so then the interquartile range is:
We know that below the third quartile we have 75% of the values and below the first quartile we have 25% of the values. Then between the third and the first quartile we will have 75-25%=50% of the values.
And then we can apply the following proportion rule:
And solving for x we got:
So then the total of students is approximately 708
13x-8<span>≤-32 would be the answer.
You have a product of 13 and a number x (which would be 13x) and you subtract 8 from it (this is because "8 less than the product of 13 and a number x"). The reason for the </span><span>≤-32 part should be easy to figure out, it's right there in the problem :-)</span>
The answer is 95% percent
We have the following equation:
h (t) = - 16t ^ 2 + 161t + 128
We substitute the value of h (t) = 170:
170 = -16t ^ 2 + 161t + 128
We rewrite the equation:
-16t ^ 2 + 161t + 128 - 170 = 0
-16t ^ 2 + 161t - 42 = 0
We look for the roots of the equation:
t1 = (161/32) + root (23233) / 32
t2 = (161/32) - root (23233) / 32
Answer:
The object is 170 feet off the ground at the following times:
t1 = (161/32) + root (23233) / 32
t2 = (161/32) - root (23233) / 32
