Answer:
262 in[tex]^{3}[/tex]
Step-by-step explanation:
the equation for volume of a sphere is : [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r[tex]x^{3}[/tex]
so replacing the number of the radius into the equation, it would look like:
[tex]\frac{4}{3}[/tex][tex]\pi[/tex]r[tex]5^{3}[/tex]
which gives you 523.59878 in[tex]^{3}[/tex]
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in[tex]^{3}[/tex]

Mark wants to test his hypothesis that he will have an equally likely chance of drawing 4 straws, given 3 are long and 1 is short. In his experiment, the long straw was drawn 85 times and the short straw 15 times. Which conclusion BEST supports his results?
A.The straws were not equally likely because the short straw was drawn more times.
B.A conclusion cannot be determined due to the fact he did not conduct 1000 trials.
C. The 4 straws are equally likely based on these results.
D.The short straw has a less likely chance of being drawn based on these results.
Answers
Answer:
the answer is D
Step-by-step explanation:
this is because the short straw was draw less than the long straw in 100 trials.

Part B: How many packets of chocolate wafers and cheese wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer. (5 points)
someone please actually explain this to me. maybe even use real words this time?! this is my last assignment for the year and here I am, wet keyboard from tears, breaking my pencil into tiny bits because of this one algebra question. if I get a bad score on this quiz i'm actually going to have a full-on meltdown! someone for the love of god explain this to me in a way that my adhd brain will understand before I throw myself into the sun. much thanks! :,)
Answers
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers

For all of the graphs:
Start the point on the number that I got from the inequality.
A filled circle means:
Greater than or equal to or less than or equal depending on where the line goes.
A hallow circle means:
Greater than or less than also depending on where the line is pointed towards too.
In order to graph an inequality you have to find and simply first then graph it.
For example on number 1, K ≤ -4.
Let's graph!
As you can see I filled in the circle and started at the point, -4.
Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.
I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.

Match each event to the likelihood of its occurrence. rolling a six-sided die and getting a 7 randomly selecting a girl from a team of 14 boys and 4 girls randomly selecting a short straw from a set of 12 short straws and 12 long straws picking a bird from a list of 20 bird species and 6 other animals likely arrowRight impossible arrowRight unlikely arrowRight neither likely nor unlikely arrowRight
Answers
A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)
14 + 4 = 18 total boys and girls
Picking a girl would be 1/18 this is low so ( unlikely)
12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)
20 + 6 = 26 total animals
Picking a bird = 20/26 = 10/13, this is high ( likely)
