Answer:
comparison of two sample proportions independent
Step-by-step explanation:
Given that the percent of managers at High Tech Inc. that pay over $8 per day for lunch is the same as the percent of technicians.
The data can be given as follows:
The samples are as follows
Managers 60 149
Who paid >8 46 98
Hence we compare sample proportions here.
The appropriate test would be

Answer:
parametric equation: q = (2-t)x + (2+t)y + (3-4t)z
symm equation:
Step-by-step explanation:
Parametric equation is just like the point slope equation:
y= b + mx
but in this case we have multiple variable so it'll be
q= p₀ + dt
p₀ will be any of your point. d will be the vector containing points shared by both your vector. It can be found by subtracting your two points together.
t is just an arbitrary variable.
Solve for d=p₂ - p₁ , you can also do d=p₁ - p₂
Now plug it into your q= p₀ + dt equation.
You can plug p₂ or p₁ in for p₀. I used p₁.
The result should give you the parametric equation.
Now solve for all of them in term of t. This step is just basic algebra.
since they're all t=..., then you can set them all equal to each other to get the symmetric equation.
Answer:
Here, m is a line and we have to find the draw parallel line of line of m through a point P with the help of straightedge and compass,
The correct order of steps for constructing a line through point P that is parallel to line m are as follows,
Step 1 : Use the straightedge to draw a line n that passes through P and intersect line m, lebel the point of intersection as X,
Step 2 : Place the point of the compass on point X and draw an arc that intersect line m and n, label the intersection point A and B,
Step 3 : Without changing the width of the compass opening, place the point of compass on point P and draw an arc that intersect line n label the intersection point as C,
Step 4 : Place the point of compass on point A and open it to the width of AB,
Step 5 : With the compass opening set the width of AB, place the point of the compass On point C and draw an arc that intersects the arc that was drawn from point P lebel the intersection of arc as point Y,
Step 6 : Use the straightedge to draw PY
Answer:
Here's the list of the following sequence in the right order for you (I took the test myself and got this whole sequence right)
1. Use the straightedge to draw a line n that passes through P and intersects line m. Label the point of intersection as point X.
2. Place the point of the compass on point X and draw an arc that intersects lines m and n. Label the intersections as points A and B.
3. Without changing the width of the compass opening, place the point of the compass on point P and draw an arc that intersects line n. Label the intersection as point C.
4. Place the point of the compass on point A and open it to width AB.
5. With the compass opening set to width AB, place the point of the compass on point C and draw an arc that intersects the arc that was drawn from point P. Label the intersection of the arcs as point Y.
6. Use the straightedge to draw line PY.

Option A
P(at least 2 broken cookies) = 1 - P(X = 0) - P(X = 1)
To find the probability of getting at least 2 broken cookies in a bag containing 36 cookies, we need to calculate the probability of getting 2, 3, 4, ..., up to 36 broken cookies and then sum up those probabilities.
The probability of getting exactly 2 broken cookies can be calculated using the binomial probability formula:
P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)
Using the formula, we can calculate P(X = 2):
P(X = 2) = C(36, 2) * (0.03)^2 * (1 - 0.03)^(36 - 2)
Similarly, we can calculate P(X = 3), P(X = 4), and so on, up to P(X = 36).
Once we have calculated all these probabilities, we can sum them up to find the probability of getting at least 2 broken cookies:
P(at least 2 broken cookies) = P(X = 2) + P(X = 3) + P(X = 4) + ... + P(X = 36)
P(at least 2 broken cookies) = 1 - P(X = 0) - P(X = 1)
To calculate P(X = 0), we can use the binomial probability formula with k = 0, and for P(X = 1), we can use the formula with k = 1.
Once we have calculated P(X = 0) and P(X = 1), we can substitute them into the equation:
P(at least 2 broken cookies) = 1 - P(X = 0) - P(X = 1)
This will give us the probability of getting at least 2 broken cookies in a bag containing 36 cookies.

Answer:e and f
Step-by-step explanation:
The amount of meters left is 0.144 meters
First and foremost, it should be noted that: 1 yard = 0.9144 meter
Therefore, 10 yards to meters will be:
= 0.9144 × 10
= 9.144 meters
Since Allison uses 9 meters, the amount of thread that is left on the
spool will be:
= 9.144 meters - 9 meters
= 0.144 meters
