Answer:
31,827 ways
Step-by-step explanation:
Total number of books, n = 18
Number of books to be selected, r = 7
Since, the order of arrangement doesn't matter ;
We use the combination formula :
nCr = n! ÷ (n-r)! r!
18C7 = 18! ÷ 11!7!
18C7 = (18*17*16*15*14*13*12) ÷ (7*6*5*4*3*2*1)
18C7 = 160392960 / 5040
18C7 = 31,827 ways

Carmen needed 23 of a yard of fabric to make a shirt and a 12 yard of fabric to make a matching skirt. How much total fabric did Carmen need to buy? 1 yard of fabric 1 yard of fabric 34 yard of fabric , 3 fourths, yard of fabric 116 yards of fabric , 1 and 1 sixth, yards of fabric 56 yard of fabric
Answer:
38/3 yards
Step-by-step explanation:
Given that,
Fabric required to make a shirt = 2/3 of a yard
Fabric required to make a skirt = 12 yards
Total fabric needed,
[tex]x=\dfrac{2}{3}+12\\\\=\dfrac{38}{3}\ yards[/tex]
Hence, 38/3 yards of fabric is needed.

Choose the function whose graph is given by: (attached photo)
y= 2cos(3x)
y= -2cos(3x)
y= 2cos(pi/2 x)
y= 2cos(1/3 x)
Answer:
2cos(3x)
Step-by-step explanation:
If the function were just cos(x), then the second peak would happen at 2π. Instead though, it happen 2π / 3. That means that the coefficient of x must be 3.
At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.
That tells us that the function graphed here must be 2cos(3x).
The correct answer is option A which is the equation of the given graph is y = 2cos(3x)
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
If the function were just cos(x), then the second peak would happen at 2π. Instead, though, it happens 2π / 3. That means that the coefficient of x must be 3.
At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.
Therefore the correct answer is option A which is the equation of the given graph is y = 2cos(3x)

F 8.4
Step-by-step explanation:
4 [ 4.5 - 2(1.2)]
First, multipy 2 and 1.2
2 x 1.2 = 2.4
Then subtract 2.4 from 4.5
4.5 - 2.4 = 2.1
Last, multiply 2.1 from 4
4 x 2.1 = 8.4
Find the amount and compound interest on 5000 at 6% per annum for 3 years annual
Answer:
The amount is 5,955.08
Step-by-step explanation:
Here, we want to calculate compound interest
We can find this by using the compound interest formula
A = P( 1 + r/n)^nt
A is amount
P
is the principal = 5,000
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times per year in which the interest is compounded = 1
t is the number of years = 3
Substituting these values;
A = 5,000(1 + 0.06/1)^3(1)
A = 5000(1.06)^3
A = 5,955.08
