Answer:
Step-by-step explanation:
From the given information:
Note that the possible values of Y are 0 and 1 because;
y = 0 if X = 0 and y = 1 if X = ±1
∴

PLEASE HELP ME 12 POINTS
Answer:
∡A = 48°
∡B = 58°
∡BCA = 74°
Step-by-step explanation:
start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°
all three interior angles of a triangle must add up to 180:
74 + 4y + 3y + 22 = 180
96 + 7y = 180
7y = 84
y = 12
substitute '12' for 'y' in 3y + 22 to get 58
substitute '12' for '4y' to get 48
Find the prime factors.

The cost of shipping a package is $2.75 per pound. Jeremy wants to ship a package that has a mass of 15 kg. How much will it cost Jeremy to ship this package? Use 1 kg = 2.2 lbs.
Answer:
$90.75
Step-by-step explanation:
First we convert kilograms to pounds.
1 kg = 2.2 lb
15 kg = 15 * 2.2 lb = 33 lb
Cost of shipping: $2.75/lb
Cost of shipping 33 lb: 33 lb * 2.75/lb = $90.75
Answer: $90.75

g A cell phone company is considering using a new manufacturer to produce batteries for their phones. The company distributes a random sample of cell phones with the new batteries to 13 of their employees to record how long the battery will last with typical usage.

Be neat and clearly mark your answer. The range. The mean. The median. Q1 and Q3. The IQR. The variance. The standard deviation.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
32.3 , 28.8 , 29.1 , 29.5 , 30.8 , 31.0 , 17.5 , 34.5 , 23.5 , 33.0 , 31.7 , 28.6 , 27.4
Reordered data:
17.5, 23.5, 27.4, 28.6, 28.8, 29.1, 29.5, 30.8, 31.0, 31.7, 32.3, 33.0, 34.5
The mean ; m
Mean, m = Σx /n
Σx = 377.7
n = sample size = 13
m = Σx / n = 377.7 / 13 = 29.05
Median = 1/2(n+1)th term
= 1/2(14) = 7th term = 29.5
Range = maximum - minimum
Range = 34.5 - 17.5 = 17
Lower quartile (Q1) = 1/4(n+1)th term
1/4(14)th term = 3.5th term
(3rd + 4th) / 2
= (27.4 + 28.6) / 2
= 28
Upper quartile (Q3) = 3/4(n+1)th term
3/4(14)th term = 10.5th term
(10th + 11th) / 2
= (31.7 + 32.3) / 2
= 32
IQR = Q3 - Q1
IQR = 32 - 28 = 4
Variance : (V) = Σ(x - m)²/n-1
[(32.3-29.05)^2 +(28.8-29.05)^2 + (29.1 - 29.05)^2 + (29.5-29.05)^2 + (30.8-29.05)^2 + (31.0-29.05)^2 + (17.5 - 29.05)^2 + (34.5-29.05) ^2 + (23.5-29.05)^2 + (33.0-29.05)^2 + (31.7-29.05)^2 + (28.6-29.05)^2 + (27.4 - 29.05)^2] / 12
Variance = 19.76
Standard deviation = sqrt(variance)
Standard deviation = sqrt(19.76)
Standard deviation = 4.45

A radioactive material disintegrates at a rate proportional to the amount currently present. If Q(t) is the amount present at time t, then dQ/dt =−rQ where r>0 is the decay rate.
Required:
If 100 mg of a mystery substance decays to 81.14 mg in 4 weeks, find the time required for the substance to decay to one-half its original amount.
Answer:
For the substance to decay to one-half of its original amount, it will take:
10.6 weeks.
Step-by-step explanation:
The decay rate = dQ/dt= -rQ
Where r > 0.
100 mg of a mystery substance decays to 81.14 mg in 4 weeks
This implies that it has decayed by 18.86 mg (100 - 81.14) in 4 weeks
The rate of decay per week = 4.715 mg (18.86 mg/4)
For the substance to decay to one-half of its original amount, i.e. 50 mg (100 mg/2), it will take 10.6 (4/18.86 * 50) weeks.
We can also determine the time it will take the substance to decay by working with the decay rate and the volume of decay, thus:
Decay rate = 4.715 / week
Decay volume = 50 mg (100 mg/2)
Time for 50 mg to decay = Decay volume/Decay rate
= 50 mg/4.715
= 10.6 weeks
