Janet rolls a regular eight-sided die with numbers 1 to 8.
1/5
1/8
5/8
7/8
Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.
The formula for probability of getting an event is given by :
[tex]P=\dfrac{Favourable\ outcome}{Total\ no\ of\ outcomes}[/tex]
Here, favourable outcome = 1
Total outcomes = 8
So,
[tex]P=\dfrac{1}{8}[/tex]
So, the correct option is (b).

Step-by-step explanation:
The sun causes a flagpole to cast a shadow that measures 85 ft. from the base of the pole. At the same time of the day, a 6.5 ft. tall basketball player casts a shadow that measures 9.75 ft.
The basketball player’s little sister is 3.5 ft. tall. At the same time of the day, determine her shadow’s length to the nearest tenth of a foot.
Answer:
Length of the shadow of player's sister is 5.25 feet.
Step-by-step explanation:
From the figure attached,
AB represents the basketball player and DE is his little sister.
Height of basketball player = 6.5 ft
Length of shadow of the player = 9.75 ft
Height of player's sister = 3.5 ft
Since, ΔABC and ΔEDC are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{DE}= \frac{ED}{DC}[/tex]
[tex]\frac{6.5}{3.5}= \frac{9.75}{x}[/tex]
x = [tex]\frac{9.75\times 3.5}{6.5}[/tex]
x = 5.25 ft
Therefore, length of the shadow of player's sister is 5.25 feet.
Find the volume of the hemisphere.
Are the pink arcs congruent?
Answer:
Yes, they are congruent.
Step-by-step explanation:
Supplementary angles equal up to 180°.
70+40 = 110
180 - 110 = 70.
Angle BAE is 70°.
And, angle ADC is 70° as well.
Therefore, the pink arcs are congruent.
Find g(x), where g(x) is the translation 4 units down of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers. g(x)=
Answer: g(x) = (x+3)^2
The answer should be in the form of a(x-h)2 + k.
Since we are not translating up or down, the k value is 0. We will not be adding any values to the outputs of the original equation here. a will equal 1 since no stretches are occurring. So we are left with the h value.
f(x) = x2 is given.
g(x) = a horizontal translation of 3 units left. This means that the h value is -3, because in order to move left, you need to take 3 away from all x values (inputs). So the point (2,4) on f(x) would become (-1,4) on g(x).
How do we write this?
g(x) = f(x-h) where h = -3.
So this is g(x) = f(x - (-3)) = f(x+3)
g(x) = (x+3)^2

investifgation: when one or more poeple or maybe you syourself or really anybody doing an inquiry or study or basically checking something like a detective example is crime scene investigation
observation: something you can tell using ur 5 senses - sight, smell, touch, hear, taste

AE / AD = AB / AC
51 / 51 + 17 = x / x + 12
51 / 68 = x / x + 12
51 ( x + 12) = 68x (After cross multiplication)
51x + 612 = 68x
612 = 68x - 51x
612 = 17x
x = 612/17 = 36

Each event uses a standard deck of playing cards. The cards are chosen at random and put back after each draw.
Match each event with its theoretical probability.
You choose a red card.
You choose the queen of hearts.
You choose a club.
You choose a 5, 6, or 7. 11 :: 3 13 52
PUT THEM IN ORDER! AND I'LL GIVE YOU "⭐"
Answer:
See below
Step-by-step explanation:
The probability of choosing a red card is 1/2. Half of the cards are hearts/diamonds and half of the cards are clubs/spades.
The probability of choosing the queen of hearts is 1/52. There is one queen of hearts in a 52 card deck.
The probability of choosing a club is 1/4. 1/4 of the cards are clubs, 1/4 are spades, 1/4 are diamonds, 1/4 are hearts.
The probability of choosing a 5, 6, or 7 is 3/13. There is a 5, 6, 7 in all 4 sets, clubs, spades, hearts, and diamonds. So there are 12 total cards that either read 5, 6, or 7 out of the 52 total cards. 12/52 simplifies to 3/13.

I’m having trouble understanding this, if anyone could help me understand it I’d greatly appreciate it.
