Answer:
The money multiplier is the ratio of money supply to the money base. The money base is the sum of currency in circulation and reserves held by commercial banks.
The reserve rate is the percentage of deposits that commercial banks must hold in reserve.
If the reserve rate is 4%, the money multiplier is 10.

Ethan ran 3/4 miles. Megan ran 7/8 miles. How much further did Megan run? Answer in simplest form.
Answer:
2/16 or 0.625
Step-by-step explanation:
Find a common denominator for the two fractions. It will be 16. 3/4=12/16
7/8=14/16 or you can do it in decimal form. 3/4=.25 and 7/8= .875
.875-.25=.0.625
[tex]\large\boxed{\frac{1}{8}\ \text{miles}}[/tex]
We need to subtract Ethan's distance from Megan's. First, we need to have a common denominator in the fractions.
Multiply both the numerator and the denominator in [tex]\frac{3}{4}[/tex] by [tex]2[/tex] to get [tex]\frac{6}{8}[/tex], which is equivalent. Now, both numbers have a denominator of [tex]8[/tex] and can be subtracted.
Now, simply subtract the numerators, leaving the denominator alone.
[tex]\frac{7}{8}-\frac{6}{8}=\frac{7-6}{8}=\boxed{\frac{1}{8}}[/tex]
The scale in the drawing is 2 cm : 5 m. Select from the drop down the correct numbers into the boxes to give the length, width, and area of the actual room.
The length, width, and area will be 25m, 15m, and 375m².
How to calculate the area?From the information given, the scale in the drawing is 2cm : 5m and the length and width are given as 10cm and 6cm respectively.
Length = 10cm = 10 × 2.5 = 25m
Width = 6cm = 6 × 2.5m = 15m
Area = Length × Width
Area = 25 × 15
Area = 375m²
Therefore, the area is 375m².

The scores on a psychology exam were normally distributed with a mean of 61 and a standard deviation of 5. A failing grade on the exam was anything 2 or more standard deviations below the mean. What was the cutoff for a failing score? Approximately what percentage of the students failed ?
The cutoff for a failing score is 51 and about 2.28% of the students failed the psychology exams.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Z score is given by the equation:
z = (raw score - mean) / standard deviation
Given mean of 61 and a standard deviation of 5.
The z score that corresponds to 2 or more standard deviations below the mean is -2. Hence:
-2 = (x - 61) / 5
x = 51
P(z < -2) = 0.0228

Option B) is correct 0.4068 portion of crocodiles live between 17.5 and 20.5
The lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard deviation of 2.6 years.
Z-table is tabulated data that gives the information of value of percentage of data.
standard deviation = 2.6 ; mean (μ)= 18
lives between 17.5 and 20.5
x= (20.5+17.5)/2=19
Z = (X - μ) / σ
z=-(19-18)/2.6
z= 0.38
While compare it with the z table is gives 0.4068.

A square has a perimeter of 24cm. What is the length of each side?
Quick process:
⇒ Square has 4 sides
⇒ We have been given that the perimeter is 24 centimeters
⇒ Each side is equal in value and each side added up together must equal 24.
⇒ So to finish this out we need to divide the given perimeter which is 2 4 by the amount of side a square has which is 4.
⇒ So 24/4 = 6
Check the answer:
6 + 6 = 12
12 + 12 = 24 √
Perimeter of a square =24cm
Formula=4s
So 4s=24
s=24/4
s=6
Therefore side of the square is 6cm.

Which description best compares the graphs given by the equations:
x - 5y = -5 and -5x - 25y = 25
a. parallel
b. perpendicular
c. intersecting but not perpendicular
d. None of the above.
x - 5y = -5, -5x - 25y = 25
First, you'll need to get the x variable by itself.
x - 5y = -5
+5 +5
x = 0
So x is plotted on the 0.
For the second part of the first equation, you'll be looking for what the y variable represents.
x - 5y = -5
-x -x
-5y = -5
5 5
y = 1
So y is plotted on the 1 on the vertical line above the 0.
For the first part of the second equation, you'll do the same thing as in the first equation.
-5x - 25y = 25
+25 +25
-5x = 50
5 5
x = 10
So the x for this equation is plotted on 10 on the horizontal line.
For the second part of the second equation, you will do the same thing as in the first equation.
-5x - 25y = 25
+5 +5
-25y = 30
25 25
y = 1.2
So the y for the second half of the second question is plotted on 1.2 on the vertical line.
Perpendicular means the lines may or may not be of equal length and they will not be perfectly in line with each other.
Parallel means the lines may or may not be of equal length but will be perfectly in line with each other.
Intersecting means the lines may or may not be of equal length but will touch each other.
Faruq has a identical markers, b identical pencils, and no other writing utensils in his locker. How many different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed?
Your answer should be an expression, which might involve the variables a and/or b.
The number of different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed is ab + a + b
How to calculate the different collection of writing utensils?Since Faruq has a identical markers, b identical pencils, and no other writing utensils in his locker and we require the number of collections or ways he could bring them to school without coming to school empty-handed, we use combination mathematics since order does not matter.
Now, Faruq can either come to school with one marker and one pencil or one pencil or one marker.
So, the combination for one marker and one pencil is n = a × b = ab
The combination for one marker is n' = a
The combination for one pencil is n" = b
So, the total combination is N = n + n' + n"
= ab + a + b
So, the number of different collections of writing utensils could Faruq bring to class if he doesn't want to show up empty-handed is ab + a + b

A perfect square is a number that can be achieved by multiplying a number by itself.
Example: 100 = 10 x 10, so it is a perfect square
2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.
