Two pirates were playing with golden coins. During game, the first pirate lost half of his coins to the second pirate, then the second pirate lost half of his coins to the first pirate, then again the first lost half of his coins to the second. At the end of the game, the first pirate had 21 coins, and the second had 45 coins. How many coins did the first pirate have initially?

Answers

Answer: 33
1st Pirate 2nd Pirate
Lost 1/2 Gained 1/2
Gained 1/2 Lost 1/2
Lost 1/2 Gained 1/2
End#: 21 End#: 45

Add 21 and 45
Which equals 66
Then divide 66 by two
Which equals 33
So both pirates started off with 33 coins each

So now we apply the losses and gains to those coins

1st Pirate: 33 2nd Pirate: 33
-1/2= 16.5 +1/2= 49.5
+1/2=41.5 -1/2= 24.75
-1/2= 20.75 +1/2= 45.5

Round 20.75 to the Round 45.5 half down:

An airplane takes off from an airport. When the
airplane reaches a height of 16,500 feet (ft), the
airplane has travelled a horizontal distance of 6,000 ft,
as shown in the diagram below.

Answers

The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft

Calculation of the distance travelled

To calculate the angle of elevation of the airplane

tan x° = opposite/adjacent

where opposite = 16,500 feet

adjacent = 6,000 ft

tan x° = 16,500 / 6,000

tan x° = 2.75

X = arctan ( 2.75)

X = 70°

To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.

C² = a² + b²

C² = 16,500² + 6,000²

C² = 272250000 + 36000000

C² = 308250000

C= √308250000

C= 17,557ft

A. What is the slope of the line? Show your work.

B. What is the y intercept of the line?

C. What is the slope intercept form of the equation of the line?

D what is he standard form of the equation of the line?

Answers

Answer:

Hi!

The slope of the line is marked as rise over run and in slope intercept form it is mx. We can tell from the way the line is slanting that it is a positive slope. It goes up 1, over 6. So therefore, the slope is 1/6.

The y intercept of the line is -4, which we know because that is where the line and the y axis meet. The y intercept is b in slope intercept form.

The slope intercept form is y = 1/6x -4.

For standard form, we subtract 1/6x from both sides to get

-1/6x + y = -4

then find the measure of ZB.

Answers

Answer:

m<ZB is 36 degrees

Step-by-step explanation:

Since they are vertical angles, they are congruent. U set up the equation like this “2x+26=3x+21” and solve for x

subtract 2x from both sides and you’ll get “26=x+21”

subract 21 from both sides and you’ll get “5=x”

now we substitute x for 5!

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total pieces of fruits = 50 pieces

Number of apple pieces = 10

Probability of apple pieces from the whole pieces = 10/50 = 0.2

Number of banana pieces = 15

Probability of banana pieces from the whole pieces = 15/50 = 0.3

Number of lemon pieces = 6

Probability of lemon pieces from the whole pieces = 6/50 = 0.12

Number of orange pieces = 14

Probability of orange pieces from the whole pieces = 14/50 = 0.28

Number of pear pieces = 5

Probability of pear pieces from the whole pieces = 5/50 = 0.1

Hence the correct probability are B. Probability 0.2 0.3 0.12 0.28 0.1.

Answers

Step-by-step explanation:

we can easily count this, as the diagonal lines are squares truly in half. so, 2 such cut squares are in total 1 full square.

there is one central rectangle of 4×6 squares = 24.

then in the upper left corner there is a small 2×2 square = 4.

and then we have in the bottom left 2 and the bottom right also 2 small triangles (4 in total) with each having 1 full square and 2 half-squares (2 squares in total) as area.

so, 4×2 = 8 squares.

so, the whole area is

Based on the provided dot plot, where there are 4 dots above each value from 5 to 10, the distribution can be described as uniform.

Uniform distribution refers to a distribution where the data points are evenly spread out across the range without any noticeable skewness or clustering. In this case, since there are an equal number of dots above each value within the given range, the distribution is uniform.

O A. No; the graph fails the vertical line test.
B. Yes, there are no y-values that have more than one x-value.
C. Yes; the graph passes the vertical line test.
D. No; there are y-values that have more than one x-value.

Answers

Answer: A. No; the graph fails the vertical line test.

The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.

For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.

Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.
