In Hillsboro's wig shop, 1/2 of the wigs are blonde and 1/12 of the wigs are brunette. What fraction of the wigs are either blonde or brunette?
Answer:
7/12
Step-by-step explanation:
So, the probability of picking up a blonde wig = 1/2
The probabiliy of picking up a brunette wig = 1/12
The question asks to find th eprobability of picking up either of these types of wigs =
1/2 + 1/12
= 6/12 + 1/12 ( LCM of 12 and 1 is 12 )
= 7/12

An aquarium holds 11.95 cubic feet of water, and is 2.8 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
3.05feet
Step-by-step explanation:
Given data
Volume = 11.95 cubic feet
Lenght = 2.8 feet
Width= 1.4feet
Depth= ????
We know that the expression for the volume is
V= L*W*D
substitute
11.95= 2.8*1.4*D
11.95= 3.92D
divide both sides by 3.92
D= 11.95/3.92
D= 3.05
Hence the depth is 3.05feet approx

If AB is translated right 5 units and down two then both points are translated by that amount.
A currently is (-5, 2)
x=-5 and y=2
Since youre going right by five your x value will increase by 5 so the point will instead be at x=0
Since youre going down by two your y value will decrease by 2 so the point will instead be at y=0
x=0 and y=0

2 is a half of 4 and 4 is a half of 8 so they both basically 1/2
can i have brainly
Answer:
They are equal!
Step-by-step explanation:
If you simplify 4/8 you would get 1/2, because 4 is half of 8. And if you look at 2/4 that simplifies to 1/2, because 2 is half of 4. I Hope This Helps :)

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.
Answer:
(1165, 1235) (hours)
Step-by-step explanation:
The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:
(1200 - 35, 1200 + 35), or
(1165, 1235) (hours)
This is an application of the Empirical Rule.
The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
What is the standard deviation?It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.
With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.
The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:
The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;
(1200 - 35)=1165
( 1200 + 35)=1235
(1165, 1235) (hours)
Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

what is the area of a circle with a diameter of 18.2 cm?
use 3.14 for TT and round your final answer to the nearest hundredth.
the area is ___ square cm.
Answer:
260.0234 cm
Step-by-step explanation:
The formula for area of a circle is π r².
Since the radius is half of the diameter, we must divide the diameter by 2.
18.2/2 = 9.1
Next, we must multiply 9.1 x 9.1.
This gives us 82.81
Now we must multiply 82.81 by pi (3.14).
82.81 x 3.14 = 260.0234
Therefore, the area of the circle is 260.0234.

Answer:
137 square feet
Step-by-step explanation:
To find the area of this figure, you will need to combine the area of the triangle and the rectangle. The area formula of a triangle is A = 1/2lw (l = length, w = width). You just find the area the same way you would the rectangle and the divide it by 2. 6 times 3 is 18, and 18 divided by 2 is 9. The area of the triangle is 9 square feet. To find the area of the rectangle, multiply the length and the width (16 and 8). The product is 128. 128 + 9 = 137.
