Answer:
675 samples
752 samples
Step-by-step explanation:
Given that :
α = 90%
E = 0.03
Previous estimate (p) = 0.34
Estimated sample proportion (n)
n = p *q * (Zcritical /E)
Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05
Z0.05 = 1.645 ( Z probability calculator)
q = 1 - p = 1 - 0.34 = 0.66
n = 0.34 * 0.66 * (1.645/0.03)^2
n = 674.70
n = 675
B.) without prior estimate given ;
p and q should have equal probability
Hence ;
p = 0.5 ; q = 0.5
n = 0.5 * 0.5 * (1.645/0.03)^2
n = 751.67361
n = 752

What is division?Division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items. It is an operation used for equal grouping and equal sharing in math.
According to the question
Number of 1/4 cups servings are in 5/8 cup:
Based on the given conditions:
= [tex]\frac{5}{8} \div\frac{1}{4}[/tex]
= [tex]\frac{\frac{5}{8} }{\frac{1}{4} }[/tex]
= [tex]\frac{5}{8\times4}[/tex]

The combined height of the world’s three tallest buildings is 6,360 feet. The building in Dubai is 745 feet taller than the building in Makkah. Taipei’s building is 301 feet shorter than Makkah’s.
The equation (x + 745) + x + (x – 301) = 6,360 represents the scenario.
What can be determined from the given information? Check all that apply.
x represents the height of the building in Dubai.
The expression (x – 301) represents the height of the building in Taipei.
The building in Makkah is 1,972 feet tall.
The height of Dubai’s building is 1,227 feet tall.
The height of Taipei’s building is 1,671 feet tall.

-4.75=z/2
PLEASE HELP............
Answer: Z= -9.5
Step-by-step explanation:
write the division as a fraction
-4.75=1/2Z
Multiply both sides of the equation by 2
-9.5=Z
then swap the sides of the equation
Z= -9.5
And if they are asking for fraction form then its either
Z= - 19/2, or Z= -9 1/2

Which ordered pairs are solutions to the system of inequalities?
More than one answer
y ≥ x + 2
y > -5/2x - 3.
A. (0,0)
B. (-2,2)
C. (0,2)
D. (-1,6)
Answer:
C, D
Step-by-step explanation:
We can solve this graphically and analytically.
Graphically, looking at the attached image below, if we graph the two inequalities and plot the points, you can find the points which are solutions by finding the points in the overlapping area.
This obviously excludes A as it only appears in [tex]y \geq x+2[/tex]
C is included as y [tex]\geq x+2[/tex] includes the point on the line.
D is obviously a solution.
B is however not a solution because is lies on the line [tex]y = \frac{-5x}{2} - 3[/tex], which the inequality excludes.
Analytically, if we can find one of the two inequalities where it is not a solution, it is not a solution of the system.
A: (0, 0)
[tex]y \geq x+2\\0 \geq 0 + 2\\0 \geq 2\\false[/tex]
A is not a solution
B: (-2, 2)
[tex]y \geq x+2\\2 \geq -2 + 2\\2\geq 0\\true[/tex]
[tex]y > \frac{-5x}{2} -3\\2 > \frac{-5(-2)}{2} - 3\\2 > 5 - 3\\2 > 2\\false[/tex]
B is not a solution
C: (0, 2)
[tex]y \geq x+2\\2 \geq 0 + 2\\2 \geq 2\\true\\\\y>\frac{-5x}{2}-3\\2 > -3\\true[/tex]
C is a solution
D:
[tex]y \geq x + 2\\6 \geq -1 + 2\\6 \geq 1\\true\\\\y > \frac{-5x}{2} - 3\\6 > \frac{-5(-1)}{2} - 3\\6 > \frac{5}{2} - \frac{6}{2}\\6 > \frac{-1}{2}\\true[/tex]
D is a solution

the line passing through the points (-2,12) and (3, -23) intersects the line passing through which of these pairs of points
Answer:
Options (1), (2) and (3)
Step-by-step explanation:
To solve this problem we will use the property,
"A system of equations will have a unique solution if slopes of the linear equations are different"
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of a line passing through (-2, 12) and (3, -23) = [tex]\frac{12+23}{-2-3}[/tex] = (-7)
Option (1)
Slope of a line passing through (-4, 17) and (5, -28) = [tex]\frac{17+28}{-4-5}[/tex] = (-5)
Option (2)
Slope of a line passing through (-2, 16) and (2, -20) = [tex]\frac{16+20}{-2-2}[/tex] = (-9)
Option (3)
Slope of a line passing through (-6, 14) and (4, -16) = [tex]\frac{14+16}{-6-4}[/tex] = (-3)
Option (4)
Slope of a line passing through (-3, 19) and (6, -44) = [tex]\frac{19+44}{-3-6}[/tex] = (-7)
Option (5)
Slope of a line passing through (-5, 32) and (3, -24) = [tex]\frac{32+24}{-5-3}[/tex] = (-7)
Slopes of options (1), (2) and (3) are different.
Therefore, Options (1), (2) and (3) will be the correct options.
