7/8

Answers

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).

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.

Answers

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.

write these numbers in order of size starting with the smallest number. 5 to the power of -1, 0.5, -5, 5 to the power of 0​

Answers

Answer:

5^-1, 0.5, 5^0

Step-by-step explanation:

Convert all numbers so that they have the same format.

5^-1 = 0.2

5^0 = 1

Compare:

0.2 < 0.5 < 1

This would be the order of size starting with the smallest.

Make sure you use the numbers in the problem and not the ones that were simplified.

Are the pink arcs congruent?

Answers

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)=

Answers

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

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

PUT THEM IN ORDER! AND I'LL GIVE YOU "⭐"​

Answers

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.
