Answer:
Lewie Survey produces less valid result.
Step-by-step explanation:
Given:
1. Kelvin surveys every other person leaving the food area.
2. Lewie surveys every fifth person leaving the mall's main entrance.
Therefore,
Kelvin will able to produce valid result as he is surveying every person who is leaving food court.
Means,
There are high chances that would have bought food from the court.
Whereas,
Lewie is surveying every fifth person leaving the the mall's entrance.
Therefore,
Here probability to produce valid result is less as they may have not buy food or they may visited other shops.
So, Lewie survey will produce less valid result.
Answer:
r = 3
Step-by-step explanation:
q = k / 
k = q
= 1.2 x 3 x 3 = 10.8
q = 10.8/
1.2 = 10.8/
r =
= 3
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Measure of arc WZ = 175°
Measure of ∠XAZ = 105°
We need to find the measure of ∠XYZ.
As we know the angle subtended at the center is the average of the measure of arc intercepted by it angle and its vertical angles.

Hence, the value of ∠XYZ is 35°.
Hence, First Option is correct.
What is the value of the discriminant?
For this case, the discriminant will be given by
b ^ 2 - 4 * a * c
Where
b = 7
a = 3
c = 2
substituting
b ^ 2 - 4 * a * c = (7) ^ 2 - 4 * (3) * (2) = 25
Therefore the value of the discriminant is 25.
How many x-intercepts does this function have?
It has two intercepts with the x axis and can be found by equaling the function to zero. That is to say,
3x2 + 7x + 2 = 0
The results will be the interceptions with x.
What are the number of zeros for this function?
The number of zeros for this function is
two real number solutions
Because it is a quadratic function.
So basically ...
You convert the rupees in paisas. One rupee is equal to one hundred paisas, so ...
280 × 100 = 28,000
And then we divide,
28,000 ÷ 14 = 2000
