The probability that he selected a pair of khaki shorts and a white T-shirt is 2/9. The correct option is A.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that Jake packed 3 pairs of shorts for a trip: 1 khaki and 2 denim. He also packed 3 T-shirts: 2 white and 1 red. In the dark, he randomly selected a pair of shorts and a T-shirt.
The probability that he selected a pair of khaki shorts and a white T-shirt is calculated as,
P = 1 / 3 x 2 / 3
P = 2 / 9
Therefore, the probability that he selected a pair of khaki shorts and a white T-shirt is 2/9. The correct option is A.

Help plzz!! Will mark you as brainliest!!! The entrance to the Louvre Museum in Paris is a square-based pyramid. The volume of the pyramid is 9,039 with a height of 21.6 meters. What is the length of each side of the square base, to the nearest meter?
A. 29
B. 35
C. 627
D. 1,253
Answer: B
Step-by-step explanation: I worked it out but have doubts
The length of each side of the square base is 35 meters, option B is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The volume of the pyramid is 9,039
The height is of 21.6 meters.
We need to find the length of each side of the square base.
V=1/3b²h
9039=1/3×b²×21.6
9039=7.2b²
Divide both sides by 7.2
b²=1255.4
Take square root on both sides
b=35.4
b=35
Hence, the length of each side of the square base is 35 meters, option B is correct.

Step-by-step explanation:
A coconut is a fruit that is made up of a hard outer shell that is spherical. Inside, there is a thick layer of coconut meat
that forms another spherical shell around the coconut milk.
If the diameter of an entire coconut is 5 inches, and the coconut meat is 1 inch thick, then there is room for
approximately _[blank] in^3 of coconut milk.
What number correctly fills in the blank in the previous sentence?
Hint find the radius of the inside sphere and use that to calculate the volume.
Use 3.14 and pie and round your answer to the nearest hundreth if necessary
Answer: There is room for
approximately 33.49 in^3 of coconut milk.
Step-by-step explanation:
Hi, we have to calculate the volume of milk inside the coconut:
First, we have to find the diameter of that volume that is equal to the diameter of the entire coconut minus the thickness of the coconut meat:
5-1 = 4 in (diameter)
Now, we simply have to apply the next formula:
Volume of a sphere: 4/3 π radius^3
Since: radius = diameter /2
V = 4/3 π (d/2)^3
Replacing with the values given:
V = 4/3 (3.14) ( 4/2)^3 = 33.49 in3

Answer:
The grapefruit is 20% heavier than the apple
Step-by-step explanation:
Say the orange's weight is o.
Grapefruit = 1.08o
Apple = 0.9o
So to find the percentage the grapefruit is bigger, you have to first do 1.08 - 0.9 = 0.18
0.18 / 0.9 = 0.2
0.2 = 20%

If f(1)=6 and f(n)=-5f(n-1)-4 then find the value of f(5)
Answer:
3126
Step-by-step explanation: f(1)=6 and f(n)=5f(n-1)-4. This means that next number is 5 times previous number minus 4.
f(2)=5f(1)-4 =5x6-4 = 30-4 = 26
f(3)=5f(2)-4 =5x26-4 = 130-4 = 126
f(4)=5f(3)-4 =5x126-4 = 630-4 = 626
f(5)=5f(4)-4 =5x626-4 = 3130-4 = 3126
The fifth term of the sequence is 4166
Given the recursive function expressed as;
f(n)=-5f(n-1)-4
If f(1 ) = 6
f(2) = -5f(1) - 4
f(2) = -5(6) - 4
f(2) = -30 - 4
f(2) = -34
If n = 3
f(3) = -5f(2) - 4
f(3) = -5(-34) - 4
f(3) = 170 - 4
f(3) = 166
If n = 4
f(4) = -5f(3) - 4
f(4) = -5(166) - 4
f(4) = -830 - 4
f(4) = -834
If n = 5
f(5) = -5f(4) - 4
f(5) = -5(-834) - 4
f(5) = 4170 - 4
f(5) = 4166
Hence the fifth term of the sequence is 4166

You want the determinant of the matrix ...
[tex]\left[\begin{array}{ccc}4&3&2\\-3&1&5\\-1&-4&3\end{array}\right][/tex]
One way to figure it is as the difference between the sum of products of the down-diagonals and the sum of products of the up-diagonals:
D = (4)(1)(3) +(3)(5)(-1) +(2)(-3)(-4) -(-1)(1)(2) -(-4)(5)(4) -(3)(-3)(3)
= 12 -15 +24 +2 +80 +27
D = 130
The determinant of the coefficient matrix is 130.

10% GST) to a dressmaker. The merchant makes $60
on the sale and passes the $6 GST onto the Australian
Tax Office (ATO)
A dressmaker uses the fabric and sells the product
onto a retail store for $143 (this includes the $13
GST). As the dressmaker has already paid $6 in GST
when they bought the fabric they have a GST tax credit
of $6 and they pass on the $7 to the ATO.
The retailer sells the dress for $220, including $20
GST. As the retailer has already paid $13 in GST to the
dressmaker, they are required to forward the extra $7 to the ATO.
The consumer who buys the dress bears the $20 GST included in the price.

k) 2^x = 32
Take logs of both sides
log 2^x = log 32
x log 2 = log 32
x = log 32 / log 2 Using your calculator to find the log values:
x = 5.
r) 9^(x + 1) = 81
log 9^(x + 1) = log 81
x + 1 log 9 = log 81
x + 1 = log81 / log9 = 2
x + 1 = 2
x = 1.
The above method is a general way to do these using logs but with some of the simpler ones you don't have to use logs at all:
For example :
3^x = 27
We know that 3^3 is 27 so
3^x = 3^3 and so:
