A company introduced a much smaller variant of its tablet, known as the tablet junior. Weighing less than 11 ounces, it was about 50% lighter than the standard tablet. Battery tests for the tablet junior showed a mean life of 10.25 hours. Assume that battery life of the tablet junior is uniformly distributed between 7.5 and 13 hours.
(a)
Give a mathematical expression for the probability density function of battery life.
f(y) =
(b)
What is the probability that the battery life for a tablet junior will be 10.5 hours or less? (Round your answer to four decimal places.)
(c)
What is the probability that the battery life for a tablet junior will be at least 11.5 hours? (Round your answer to four decimal places.)
(d)
What is the probability that the battery life for a tablet junior will be between 8.5 and 10.5 hours? (Round your answer to four decimal places.)
(e)
In a shipment of 100 tablet juniors, how many should have a battery life of at least 12 hours? (Round your answer to two decimal places.)
tablet juniors
Answer:
showed a mean life of 10.25 hours. Assume that battery life of the tablet junior is uniformly distributed between

6 + 3 (10× - 22) could someone please help me solve this
Answer:
x = -2
Step-by-step explanation:
6 + 3(10x-22)
3 * 10x = 30x
3 * -22 = -66
6 + 30x = -66
-66 + 6 = -60
30x = -60
-60/30 = -2
x = -2
Louis has a bag of 2510 shells each pen shell is 18 cm long what is the combine length of the pen shells in meters
Answer:
45180cm
Step-by-step explanation:
You have to multiply the amount of shells by the length on one shell to get the length of all of them combined so, 2510 multiplied by 18 is 45180.

Answer:
its C
Step-by-step explanation:
because 180⁰-40⁰=140⁰
Answer:
∠m = 140°
Step-by-step explanation:
∠1 and ∠m are adjacent angles, so they add up to 180°.
∠1 + ∠m = 180
40 + ∠m = 180
∠m = 180 - 40
∠m = 140°

can someone teach me how this goes? geometry , inscribed angles but circles
Answer:
60
Step-by-step explanation:
So basically all you need to know for this one is that when there is an inscribed angle, the angle measure is 1/2 of the measure of the arc for that angle.
That might sound confusing, but an example from the picture is that angle ABC will be half of arc AC. This means that angle ABC is 1/2 of 120 = 60 degrees.
The answer is 60 degrees.

Answer:
2/3+2/3=4/3 or 1 1/3
Step-by-step explanation:
I figured it out!!
it should be greater than. the reasoning for this is if you equally split a rectangle into 3 pieces and then also split the same sized rectangle into equal pieces then which pieces would be bigger? the Rectanhle that is split into 3! this is because you have less pieces to split the rectangle into so the less you have too split the rectangle to larger the pieces are!!
Answer:
2/3+2/3 is greater than 1 1/4, so Edward does not have enough oil
Step-by-step explanation:
2/3+2/3=4/3, or 1 1/3
So now it's is 1 1/3 greater than or less than 1 1/4, which is just a matter of if 1/3 is greater than 1/4. 1/3 is 0.33 repeating, and 1/4 is 0.25, so 1/3 is greater than 1/4
1 1/4 is the amount of oil he has, and 1 1/3 is the amount required, which is more than he has so therefore he can't make 2 batches

Write the equation of the line passing through (2,0) and (0,-5)
Answer:
y=5/2x+2
Step-by-step explanation:
To get the slope,
(-5-0) /(0-2)=-5/-2=5/2
Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.
What is the value of y in the equation 9 + y = 8?
72
17
1
−1
y = -1
Get the variable on one side of the equation...
9 + y = 8
9 + y - 9 = 8 - 9
y = -1
Answer:
y = -1
Step-by-step explanation:
This is a one-step equation. All you have to do is subtract the 9 from the left side to move it to the right side. This would give you an answer of y = -1.
