The formula for the area of a triangle:
[tex]A=[/tex] [tex]\frac{H*B}{2}[/tex]
Substitute area and base:
[tex]1296 = \frac{H*6}{2}[/tex]
Multiply by the denominator to eliminate the fraction:
[tex]2*1296 = \frac{H*6}{2} *2\\[/tex]
[tex]2592=H*6[/tex]

Step-by-step explanation:
FV = PV (1+i)^n
FV = future value = 15100 PV = present value = 6000
i = period interest in decimal = .065/2 = =.0325

We know only 1 slice of cheese pizza was left so that would mean 7 slices were eaten. (8-1=7)
2 pepperoni pizza slices were eaten so 6 are left. (8-2=6)
2 slices of sausage pizza was left so that would mean 6 were eaten. (8-2=6)
7 slices of cheese pizza were eaten, 2 pepperoni slices were eaten, and 6 slices of sausage pizza were eaten. 7+2+6 = 15.
That means 15 slices of pizza were eaten. Hope this helps and please mark brainliest!

The correct interpretation of the standard deviation of the given discrete distribution is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
What are the mean and the standard deviation of a discrete distribution?The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.The standard deviation is the square root of the sum of the difference squared between each outcome and the mean, multiplied by it's respective probabilities.Hence:
E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36
[tex]\sqrt{V(X)} = \sqrt{0.4(0-1.36)^2 + 0.12(1-1.36)^2 + 0.13(2-1.36)^2 + \cdots + 0.01(7-1.36)^2} = 1.674[/tex]
Hence the correct option is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.

Answers
The mean of a given set 3, 3, 2, 2, 2, 8, 8, 4 is 4. if the number 4 were added to the set then it won't change in mean.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
The given set is
3, 3, 2, 2, 2, 8, 8, 4
The mean will be
Mean = Sum of observations/the number of observations
= [tex]\frac{3+ 3+ 2+ 2+ 2+ 8+ 8+ 4}{8} \\\\\frac{32}{8} \\\\4[/tex]
if the number 4 were added to the set.
4 + 32 we get 36 and since you added one more number, we will take a number of terms 9.
So, the mean becomes

The area of a 2D form is the amount of space within its perimeter. The area of the right triangular prism is 1,200 m².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the triangular prism can be written as,
Total surface Area
= Area of two rectangle face + Area of two triangular face + Area of base
= 2(17×15) + 2(0.5×30×8) + (30×15)
= 2(255 in²) + 2(120 in²) + 450 in²

What is the conditional probability that exactly four heads appear when a fair coin is flipped five times, given that the first flip came up heads?.
Answers
Answer:
Step-by-step explanation:
wow, they really try to make these probablity questions difficult. so they say 5 but really, b/c the 1st one is heads , we are tossing the coin 4 more times, to find 3 heads b/c we already got one. wow, I'm mad at the teacher that asked this. :P Just say 4 flips for 3 heads.
P(H) = heads
P(H) =1/[tex]2^{4}[/tex] probability is 1/[tex]2^{4}[/tex] because we have two outcomes and four tries.
P(H) = 1/16
P(H>=3) 3 * 1/16
P(H>=3) = 3/16
if there is an argument that you have to take 1/[tex]2^{5}[/tex] into account by the teacher tell them that it was already resolved , the first flip is not a "probablity" any longer. It's heads, 100% , it doesn't affect the next tosses b/c this is a "fair" coin and it's going to land on heads 50% of the time, for every toss. Just my rant. :P
