Answer:
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922
Step-by-step explanation:
Step(i):-
Given that the mean of the Normal distribution = 4.1mm
Given that the standard deviation of the Normal distribution = 0.0075mm
Let 'X' be the random variable in a normal distribution
Given that X₁ = 3.9mm
[tex]Z_{1} = \frac{X_{1} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{3.9 -4.1}{0.075} = -2.666[/tex]
Given that X₂ = 4.3mm
[tex]Z_{2} = \frac{X_{2} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{4.3 -4.1}{0.075} = 2.666[/tex]
Step(ii):-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = P(-2.666≤Z≤2.666)
= P(Z≤2.666)-P(Z≤-2.666)
= 0.5 +A(2.666) - (0.5-A(2.666)
= 2 × A(2.666)
= 2×0.4961
= 0.9922
Final answer:-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922

Daniel says that more than half the students spent 2 1 2 hours or more on homework. Liz says more than half the students spent less than 2 1 2 hours on homework. Who is correct? Explain.
Answer:
Liz is correct
Step-by-step explanation:
Given
See attachment for complete question
Required
Who is correct? Daniel or Liz
From the attached data, we have:
[tex]Time: 1\frac{3}{4},\ 2\frac{1}{2},\ 2,\ 2\frac{3}{4},\ 1,\ 1\frac{3}{4},\ 1\frac{1}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4},\ 2,\ 2[/tex]
The total number of students is:
[tex]n = 12[/tex]
The data that represents [tex]2\frac{1}{2}[/tex] or more is:
[tex]Time: 2\frac{1}{2},\ 2\frac{3}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4}[/tex]
The frequency of this is 5
The frequency that represents [tex]2\frac{1}{2}[/tex] or less will be 7
This means that less than half spend [tex]2\frac{1}{2}[/tex] or more
and more than half spend [tex]2\frac{1}{2}[/tex] or more
Hence, Daniel is incorrect. Liz is correct

LA = [ ? ]cm?
Hint: Lateral Area of a Cone = tre
Where e = slant height
Answer:
Step-by-step explanation:
Answer:
200π cm^2
Step-by-step explanation:
Sb = 8^2 π = 64π cm^2
a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm
Sl = 8x17xπ = 136 π cm^2
SA = 136π + 64π =200π cm^2

If the airplane had to return to the airport, how far would it have to travel?
A. 154.11 miles
B. 283.8 miles
C. 207.70 miles
D. 249.22 miles
Please help!! :00
Answer:
The answer is B. 283.8 miles.[tex]\sqrt{b^2[/tex]
Step-by-step explanation:
Using the cosine rule:
b^2 = a^2 + p^2 - 2ap(cosB)
b^2 = 172.20^2 + 111.64^2 - 2 x 172.20 x 111.64(cos177.29)
b^2 = 42,116.33 - 38,448.82(cos177.29)
b^2 = 42,116.33 - (-38,405.82)
b^2 = 42,116.33 +38,405.82
b^2 = 80,522.15
[tex]\sqrt{b^2[/tex] = [tex]\sqrt{80,522.15}[/tex]
b = 283.76 miles = 283.8 miles

Look at the data on the line plot. A line plot shows a number line 0.1 to 0.7 in intervals of 0.1. 0.1 has 1 dot. 0.5 has 2 dots. 0.6 has 4 dots. 0.7 has 1 dot. Which data value would be considered the outlier? Enter your answer in the box.
Answer:
0.1 is the outlier
Step-by-step explanation:
Though the question has a missing attachment (of the line plot), the question can still be answered.
The given data can be represented as;
[tex]\begin{array}{cc}{} &{Dots} & {0.1} & {1} & {0.5} & {2} & {0.6} & {4} & {0.7} & {1} \ \end{array}[/tex]
Notice that 0.1 is not as close as to other data as the closeness of 0.5, 0.6 and 0.7.
This implies that 0.1 is an outlier.
Answer:
0.1 is the outlier
Step-by-step explanation:
Look at the data on the line plot.
A line plot shows a number line 0.1 to 0.7 in intervals of 0.1. 0.1 has 1 dot. 0.5 has 2 dots. 0.6 has 4 dots. 0.7 has 1 dot.

Answer:
B
Step-by-step explanation
f(x)=x2-4x-5
Becomes
f(x)=x2-5x+x-5
Take out the common factor
f(x)=(x-5)(x+1)
Equate the given function equal to 0
0=(x-5)(x+1)
And then
x-5=0 -- x=5
x+1 = 0 == x=-1
Answer:
B
Step-by-step explanation:
we are given a quadratic function
we want to figure out the form which we don't need change
so according to the question
[tex] \displaystyle{x}^{2} - 4x - 5 = 0[/tex]
rewrite -4x as x-5x:
[tex] \displaystyle{x}^{2} + x - 5x- 5 = 0[/tex]
factor out x:
[tex] \displaystyle \: x({x}^{} + 1)- 5x- 5 = 0[/tex]
factor out -5:
[tex] \displaystyle \: x({x}^{} + 1)- 5(x + 1 )= 0[/tex]
group:
[tex] \displaystyle \: (x + 1 )(x - 5)= 0[/tex]
hence our answer is B

Answer:
5
Step-by-step explanation:
8 times 15 equals 120, so if the volume is 600, 600/120 or 600/ 8 times 15 is equal to 5
need help thank u
:)
The area of the base is 1/2 x s x s = 1/2 x 12 x 12 = 72 square cm
Volume = area of base x height/3
Volume = 72 x 14/3 = 336 cm^3
Definitely could use some help. Would also be really appreciated if someone gave a breakdown of how they solved it. Thank you!!!
The rest of the side where the 8 is would 20 (28-8)
Set up proportions:
8/10 = 20/3x-5
Cross multiply
200 = 24x-40
Add 40 to both sides
240 = 24x
Divide both sides by 24
X = 10
Solve for the equation: 3x-5 = 3(10)-5 = 30-5 = 25

The length and breadth of a rectangular ground is 30 m and 20 m respectively.A boy moves around the ground 5 times early morning everyday.Find the distance covered by him?
Answer:
500m
Step-by-step explanation:
a rectangle has 4 sides, so 30=60 and 20=40
60x5=300
40x5=200
300+200=500
500m
reason of 500
The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.
