Answer: 0%
Step-by-step explanation:
There are 5 colors of jelly beans.
Kaz ate all the green beans, so now only 80% of the jelly beans remain.
Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.
Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.
Current numbers: 0% green, 5% orange, 10% red, yellow, blue
Then he eats red and yellow candies in equal proportions until only 15% of the beans remain. This means that he ate 20% worth of red and yellow beans. This means that he ate all of the red and yellow beans.
Thus, there are 0% red beans left.
So remember that the area of a circle is A = π * r^2, with r = radius. In this case, the radius is 1.5, and with that info our equation is A = π * 1.5^2 .
For this, all you need to do is solve the exponents, and your answer is A = 2.25π yds^2
Answer: 10 and 3
Step-by-step explanation:
A coefficient is a number placed before a variable so its 10 and 3 in this expression.
Answer: ( 8.11 , 9.69)
the 95% confidence interval of the true mean weight
= ( 8.11 , 9.69)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 8.9
Standard deviation r = 0.9
Number of samples n = 5
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
8.9+/-1.96(0.9/√5)
8.9+/-1.96(0.4025)
8.9+/- 0.79
= ( 8.11 , 9.69)
Therefore at 95% confidence interval (a,b) = ( 8.11 , 9.69)
Answer:
7: B, 8: A
Step-by-step explanation:
7. The domain of a function is the set of all of the values of x that are in it. In this case, we are given a series of points, so the domain of the function will be the set of x-coordinates of the points. The x-coordinate of a point is the first coordinate in the ordered pair representing the point. For example, in (0, 1), the x-coordinate is 0.
Applying that here, the x-coordinates of the points are 8, 5, 9, and 6, or 5, 6, 8, 9 in ascending order. Therefore, the domain of the function is {5, 6, 8, 9}, or option B.
8. In a system of coordinates, an abscissa is simply an x-coordinate (option A). For example, in our previous example point, (0, 1), the abscissa would be 0, because the point's x-coordinate is 0. Hope this helps!
