Answer:
± 5.919
Step-by-step explanation:
Margin of Error formula = z × standard deviation/√n
Z score for 99% confidence interval = 2.58
n = 19
Standard deviation = 10
Margin of Error = 2.58 × 10/√19
= ± 5.9189259339
Approximately to 3 decimal place = ± 5.919

In a music competition, a participant has to score a total of at least 40 points in the first four rounds combined to move on to the fifth and final round. Glenn scored 4 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Glenn scored in each of the second, third, and fourth rounds if he earned a place in the finals?
4 + 3p ≤ 40
4 + 3p ≥ 40
4p + 3 ≥ 40
4p + 3 ≤ 40
Answer:
4 + 3p ≥ 40
Step-by-step explanation:
4 points in the first round plus 3p (identical scores) has to be at least 40 points or higher to move on.
Write an equation for the line?
Answer:
y = 2x + 3
Step-by-step explanation:
Given:
(2, 7) and (0, 3)
Find the slope between the two points:
(x1, y1) = (0, 3)
(x2, y2) = (2, 7)
(y2 - y1)/(x2 - x1)
(7 - 3)/(2 - 0)
4/2 = 2
m = 2
y = mx + a
y = 2x + a
Use one of the two points to find a (I will use point (2, 7):
7 = 2(2) + a
7 = 4 + a
a = 3
Slope-intercept Form: y = 2x + 3
Point-slope Form: y - 3 = 2x
Point-slope Form: y - 7 = 2(x - 2)
General equation: 2x - y + 3 = 0
Triangle ABC has vertices at A (1,-3), B (3,0)x and C (5,-3). What is the distance from vertex B to the midpoint of AC?
Answer:
The distance from vertex B to the midpoint of AC is 3 units
Step-by-step explanation:
we are given a triangle with vertices A (1,-3), B (3,0) and C (5,-3).
Mid point of of AC (x,y) = ( 1+5/2 , -3 -3/2)
= ( 6/2 , -6/2)
= (3 , -3)
Distance formula = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
= [tex]\sqrt{(3-3)^2 + (0 + 3) ^2}[/tex]
= [tex]\sqrt{(3)^2}[/tex]
= 3 units

The smiths previously lived in a house that had 1450 sq ft of space. The sq ft of their new home is 3800 sq ft. What is the percent increase of their living space?
Answer:
162.1%
Step-by-step explanation:
Given that:
Size of previous living space = 1450 sq ft
Size of new living space = 3800 sq ft
% increase in living space ;
Increase in living space = 3800 - 1450 = 2350 sq feet
(Increase / previous size) * 100%
(2350 / 1450) * 100%
1.6206 * 100%
= 162.06%
= 162.1%

what is the number if 50% of 25% of the number is 96
Let n = the number we need to find.
0.50(0.25)n = 96
0.125n = 96
Can you finish?
The number if 50% of 25% of the number is 96 is 768
Let the unknown number be x
50% of 25% of the number is expressed as 0.5(0.25)x
0.5(0.25)x = 0.125x
Equating the result to 96 will give;
0.125x = 96
Divide both sides by 0.125
0.125x/0.125 = 96/0.125
x = 96/0.125
x = 768
Hence the number if 50% of 25% of the number is 96 is 768

A plane is traveling at a constant speed of K miles per hour. Which coordinate is
represented on the graph?
A. 1,K
B. K,K
C. K,1
Brainly
Answer:
Option (A)
Step-by-step explanation:
Plane is travelling at a constant speed = K miles per hour
K = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Distance = k(Time)
For Time of traveling = 1 hour
Distance traveled = k × 1
= k miles
Therefore, k miles will be traveled in one 1 hour and ordered pairs of the given point on the line will be (1, k)
Option (A) will be the correct option.

Step-by-step explanation:
A banker earns a $75,000 annual salary, a 2,35% commission on any approved loans for the bank’s business customers, and a fee of $3.75 for each application processed. If the banker has a total of 2.8 million in approved business loans and processes 2,750 applications this year, what are the banker’s earnings rounded to the nearest dollar ??
Answer:
Amount earned = $151,113
Step-by-step explanation:
Here, we are interested in calculating the banker’s earnings rounded to the nearest dollar;
We proceed as follows; we have the following;
1. Annual salary of $75,000
2. 2.35% on approved loans.
Approved loans = 2.8 million
Commission = 2.35/100 * 2.8 million = $65,800
3. $3.75 for each processed loan application
Total = 2750
Amount = 3.75 * 2750 = $10,312.50
Total amount earned is thus;
$75,000 + $65,800 + $10,312.50 = 151,112.5 = 151,113 to the nearest dollar
Jenna is putting a ribbon around the border of a square frame. The area of the frame is 196 square inches. How long will the ribbon need to be in order to go around the whole frame?
Answer: 56 inches
Step-by-step explanation:
Given that:
Area of square frame = 196 in²
Area of a square = a²
Where a = side length
Hence side length (a) of the square :
a² = 196
a = √196
a = 14
To find the length of the ribbon required :
Find the perimeter of the square :
Perimeter of a square = 4a
= 4 * 14
= 56 inches
