d. How much current is passing through each resistor?
e. Calculate the voltage drop across each resistor.
f. How does the voltage drop across each resistor compare to the voltage of the battery?
4. Three resistors with values of 12 Ω, 24 Ω and 6 Ω are connected in series to one another and a 24 V power supply. Draw the circuit and fill in the data table.
5. Three resistors with values of 3 Ω, 5 Ω and 7 Ω are connected in a circuit, as shown. When the switch S1 is in the position shown on the diagram only two resistors, R1 and R2, are connected to the 36 V battery and the current is I1. If the switch is moved to it’s down position the third resistor R3 is connected in series to R1, R2, and the battery, producing a current I2. Find the current reading of the ammeter, I1 and I2, for the two different switch positions.

50% of students change their major area of study after their first year in a program. A random sample of 100 students in the College of Business revealed that 48 had changed their major area of study after their first year of the program. Has there been a significant decrease in the proportion of students who change their major after the first year in this program
Answer:
Hence, since z ( - 0.4 ) is greater than ( -1.65 );
we reject H₀, Null hypothesis,
Therefore, There is no evidence that there has been a significance decrease in the proportion of students who change their major after the first year in the program.
Step-by-step explanation:
Given the data in the question;
Let p = 50% = 0.5
Hypothesis;
Null hypothesis H₀ : p ≥ 0.5
Alternative hypothesis H₁ : p < 0.5
x = 48
sample size n = 100
sample proportion p" = x / n = 48 / 100 = 0.48
significance value = 0.5
[tex]Z_\alpha[/tex] = -1.65
Test Statistics;
z = (p" - p) / √( p( 1 - p ) / n )
we substitute
z = (0.48 - 0.5) / √( 0.5( 1 - 0.5 ) / 100)
z = -0.02 / √( 0.25 / 100 )
z = -0.02 / √0.0025
z = -0.02 / 0.05
z = -0.4
Hence, since z ( - 0.4 ) is greater than ( -1.65 );
we reject H₀, Null hypothesis,
Therefore, There is no evidence that there has been a significance decrease in the proportion of students who change their major after the first year in the program
Find x. Round to the nearest tenth
A: 5.0
B: 7.8
C: 3.9
D: 4.6
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{6}[/tex] ( multiply both sides by 6 )
6 × cos40° = x , then
x ≈ 4.6 ( to 1 dec. place ) → D

what two fractions divided by each other equal 11/15
Answer:
11/9 and 3/5
Step-by-step explanation:
1st equation: 3n/5 = 11/15
multiply each side by 5/3 to get:
n = 55/45 or 11/9
2nd equation: 11n/9 = 11/15
multiply each side by 9/11 to get:
n = 99/165 which reduces to 3/5

Where is the blue dot located on the number line
===================================================
Explanation:
Use the midpoint formula to find the midpoint of -10 and -4
A = -10 = left endpoint
B = -4 = right endpoint
C = midpoint of A and B
C = (A+B)/2
C = (-10+(-4))/2
C = -14/2
C = -7
The value -7 is exactly midway between -10 and -4, so that's the missing tickmark between those values. Consequently, it also means each gap is 3 units wide (i.e., distance from -10 to -7 is 3 units).
Start at -10 and subtract 3 to move to the left by that amount. Do this three times to follow this pattern:
move from -10 to -13move from -13 to -16move from -16 to -19The blue dot is located at -19

The perimeter of the hexagon is 24 m.
What is the value of x?
Answer:
3.5
Step-by-step explanation:
add the two 5 and then subtract the perimeter which is 24 , so 24-10 is 14 then divide it by 4 for the missing sides and u get 3.5
The value of x in the given hexagon is 3.5 m.
What is the Perimeter of Hexagon?
Perimeter of Hexagon is equal to sum of all sides.
Here, Two sides are 5 m long
and remains 4 sides have length x m.
Perimeter = Sum of all sides
24 = 2 X 5 + 4x
24 = 10 + 4x
4x = 24 -10
4x = 14
x = 14/4
x = 3.5 m
Thus, the value of x in the given hexagon is 3.5 m.

BRAINLIEST FOR CORRECT ANSWER!! Kenny leaves home and walks 10 blocks east and 24 blocks north to get to the movie theater. How far is the movie theater from Kenny’s home if he were to take a direct path?
Answer:
8.568cm
Step-by-step explanation:
IF Kenny leaves home and walks 10 blocks east and 24 blocks north to get to the movie theater, his distance from home to the theatre is gotten using the pythagoras theorem as shown;
d² = 23² + 10²
d² = 529 + 100
d² = 629
d = √629
d = 8.568
Hence the required distance is 8.568cm
