Answer:

Step-by-step explanation:

To calculate the number of yellow paperclips expected to be drawn if a paperclip is drawn 800 times, multiply the number of draws by the probability of drawing a yellow paperclip.

Therefore, if a paperclip is drawn a total of 800 times, a yellow paperclip is expected to be drawn roughly 180 times.

To calculate the number of blue paperclips expected to be drawn if a paperclip is drawn 80 times, multiply the number of draws by the probability of drawing a blue paperclip.

Thus, if a paperclip is drawn a total of 80 times, a blue paper clip is expected to be drawn roughly 21 times.

Finally, calculate the number of draws necessary if a green paperclip is drawn roughly 1,235 times, divide 1,235 by the probability of drawing a green paperclip.

Therefore, If a paperclip is drawn a total of 5,200 times, a green paper clip is expected to be drawn roughly 1,235 times.

Answer:

The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.

Step-by-step explanation:

Consider the provided information.

The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.

The sketch that shows parallel lines is shown in figure.

The real life example of parallel lines.

Few examples are:

1) Railroad Tracks

2) Edges of walls

3) Zebra crossing

Parallel lines are straight lines that run in the same direction, never intersect, and maintain a constant separation distance, as seen in railroad tracks.

Parallel-Lines are two or more straight lines that run in the same direction and never intersect, no matter how far they extend. They maintain a constant separation distance between them, and their slopes (steepness) are equal.

In a sketch, parallel lines are depicted as lines that are equidistant from each other and do not cross, remaining at the same distance apart.

The sketch of parallel-lines is shown below;

A real-world example of parallel lines is railroad tracks. When you observe two railway tracks running alongside each other, they serve as a practical illustration of parallel lines. They remain equidistant throughout their length and never converge, ensuring safe and efficient train transportation.

Final answer:

The zeros of the function h(x)=(-4x-3)(x-3) are x=3/4 and x=3, with the smaller solution being 3/4 and the larger solution being 3.

Explanation:

To solve for x, we need to find the zeros of the function h(x) = (-4x-3)(x-3). The zeros of a function occur where the function equals zero, so setting h(x) to zero gives us:

0 = (-4x - 3)(x - 3)

A function is zero when any of its factors are zero. We can, therefore, set each factor equal to zero and solve:

-4x - 3 = 0 => x = -3/(-4) => x = 3/4

x - 3 = 0 => x = 3

So the zeros of the function are x = 3/4 and x = 3. The smaller solution is x = 3/4, and the larger solution is x = 3.

Find the length HD

In the right triangle HDF

Applying the Pythagoras Theorem

[tex]FD^{2} =HF^{2} +HD^{2}[/tex]

substitute the values and solve for HD

[tex]19^{2} =16^{2} +HD^{2}[/tex]

[tex]HD^{2}=19^{2}-16^{2}[/tex]

[tex]HD=\sqrt{105}\ units[/tex]

step 2

Find the length JD

In the right triangle JDF

Applying the Pythagoras Theorem

[tex]FD^{2} =JD^{2} +FJ^{2}[/tex]

we have

[tex]FD=19\ units[/tex]

[tex]FJ=JG=15\ units[/tex] ----> because JD is a perpendicular bisector

substitute the values and solve for JD

[tex]19^{2} =JD^{2} +15^{2}[/tex]

[tex]JD^{2}=19^{2}-15^{2}[/tex]

[tex]JD^{2}=136[/tex]

Answer:

y=2x-8

Step-by-step explanation:

this is the answer for ttm

Answer:

Option A

Step-by-step explanation:

Given

m=( y_2- y_1)/(x_2-x_1 )

In order to get the equivalent equation, multiplying the denominator x_2-x_1with m.

m(x_2-x_1 )=y_2- y_1

Adding y1 to both sides of equation will give:

m(x_2-x_1 )+ y_1=y_2- y_1+y_1

So the end result will be:

m(x_2-x_1 )+ y_1=y_2

Can also be written as:

y_2=m(x_2-x_1 )+ y_1

Comparing it the given options gives us that Option A is the correct answer.

Answer:

Perimeter=737 feets

Area=13542.6 ft²

Step-by-step explanation:

Well assuming that a,b,c are the three sides of the triangle and h is the height then;

Perimeter=distance around the figure

P=164+221+352= 737 feet

Area of a triangle given three sides is calculated using the formulae;

Area=√s (s-a) (s-b) (s-c) where  s=(a+b+c)/2

Finding s;

s=(164+221+352)/2 =368.5 feet

Finding the area

A= √ 368.5 (368.5-164) (368.5-221) (368.5-352)

A=√368.5 (204.5) (147.5) (16.5)

A= 13542.6 ft²

Answer: 39 degrees

Step-by-step explanation: The angle sum of a triangle is 180 degrees so we take 102 from 180.

180-102=78

Since the two angles are the same then we just divide 78 by 2

78/2=39

Answer:

∠E ≈ 37°

Step-by-step explanation:

Using the Sine Rule in ΔEFG, that is

[tex]\frac{26}{sinE}[/tex] = [tex]\frac{42}{sin102}[/tex] ( cross- multiply )

42 × sinE = 26 × sin102° ( divide both sides by 42 )

sinE = [tex]\frac{26(sin102)}{42}[/tex] ≈ 0.6055..

E = [tex]sin^{-1}[/tex] (0.6055 ) ≈ 37°

to figure out the percentage, you’ll have to do 78 divided by 120 (because it’s 78/120) which is 0.65. now, you’ll have to multiply by 100, so her percentage is 65%.

9/20 is coconut milk

The proportion of coconut milk in the fruit cocktail is 9/20, which is calculated by dividing the amount of coconut milk (45 ml) by the total volume of the cocktail (100 ml), then simplifying the fraction.

To find the proportion of coconut milk in the fruit cocktail, we first add up the total amount of all the liquids that go into the cocktail. According to the question, for every 25 ml of orange juice, there is also 30 ml of apple juice and 45 ml of coconut milk mixed together. Adding these amounts gives us a total mixture volume of 25 ml + 30 ml + 45 ml = 100 ml for the cocktail.

Next, we need to find out what fraction of this total mixture is coconut milk. Since there are 45 ml of coconut milk in the total 100 ml of the cocktail, the fraction is 45/100. This fraction can be simplified by dividing both numerator and denominator by the greatest common divisor, which is 5, giving us 9/20.

Therefore, the proportion of coconut milk in the fruit cocktail is 9/20.

The answer is D on EDGE 2020

Step-by-step explanation:

Answer:

x = 35 degrees.

Step-by-step explanation:

cos x = sin(20 + x)

Using the identity cos x = sin(90 - x):

20 + x = 90 - x

2x = 70

x = 35 degrees (answer).

Answer:

Value of x is 35°.

Step-by-step explanation:

Given:

cos x = sin ( 20 + x )

To find: Value of the x.

We know that [tex]sin\,(90-\theta)=cos\,\theta[/tex]

Consider,

cos x = sin ( 20 + x )

sin ( 90 - x ) = sin ( 20 + x )

Comparing both sides,

90 - x = 20 + x

-x - x = 20 - 90

-2x = -70

x = 35°

Therefore, Value of x is 35°.

Answer:

108.505

Step-by-step explanation:

Let's talk money for just a second. Which would you rather have 20 dollars or 20.32      20dollars and 32 cents?

Isn't 20.32 bigger than 20.

You should say yes.

If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.

After comparing digits after the decimal point, 108.505 is greater than 108.5 because 505 is greater than 500.

When comparing two decimal numbers, you should compare them digit by digit, starting from the leftmost digit. In this case, both numbers start with 108, which is the same. However, when comparing the next set of digits after the decimal point, you have 505 for the first number and 5 (equivalent to 500) for the second number. Because 505 is greater than 500, the first number, 108.505, is greater than the second number, 108.5.
