Answer:
Step-by-step explanation:
The diameter of the circle is twice the radius, so the diameter of the circle is 2 x 12 inches = 24 inches.
To find the area of the circle, we can use the formula A = πr^2, where A is the area of the circle and r is the radius.
So, for this circle, A = π(12 inches)^2 = 144π square inches.
Therefore, the diameter of the circle is 24 inches, the formula to find the area of the circle is A = πr^2, and the area of the circle is 144π square inches.
Answer: 144 pie square inches!
Step-by-step explanation:
1st blank : is 24 square inches since the radius which is half the diameter is 12 square inches we can easily know that the diameter would be 24 square inches!
2nd blank : pie r squared is the formula! for all areas of the circles! the total length in other words the circumference of the circle would be 2 pie r basically multiplying 2 and pie and the radius.
3rd blank : the area of the circle is 144 pie (square inches)!

C: Y
D: Z
Answer:
26.11% of women in the United States will wear a size 6 or smaller
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
In the United States, a woman's shoe size of 6 fits feet that are 22.4 centimeters long. What percentage of women in the United States will wear a size 6 or smaller?
This is the pvalue of Z when X = 22.4. So
has a pvalue of 0.2611
26.11% of women in the United States will wear a size 6 or smaller
The area of the metal part, or the shaded region shown is 10x + 45.
= 10x + 45

Answer:
The area of the metal part or shaded area is S=10x+45.
Step-by-step explanation:
The shaded area can be calculated substracting the little square area (the hole) from the big square area (the original metal part).
This is:
The area of the metal part or shaded area is S=10x+45.
Answer:
Someone who sells 20 boxes of cards earn 3 badges.
Step-by-step explanation:
Answer:
b(20) = 3 means that for 20 boxes of cards sold, 3 badges were earned.
Step-by-step explanation:
The number of badges earned based on the number of boxes of cards sold means that badges earned are a function of the number of boxes of cards sold.
b(20) means the number of badges earned for selling 20 boxes of cards.
b(20) = 3 means that for 20 boxes of cards sold, 3 badges were earned.
