a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?

Answers

Answer 1

Answer:

The answer is 20/30 or in simplified form 2/3

Step-by-step explanation:

The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

I plugged each equation into a graphing calculator and compared them to see which one matched the one in the picture.

The value of the trigonometric equation after transformation is given by the value y = 3 [ sin ( x + 3 ) ] - 2

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as f ( x )

Now , the value of the trigonometric function f ( x ) is

f ( x ) = 3sin ( x )

when the function is translated 3 units to the left and 2 units down , we get

y = 3 [ sin ( x + 3 ) ] - 2

Therefore , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2 and the graph is plotted

Hence , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2

what is the value of X

Answers

Answer: It is 250

Step-by-step explanation: you would add 40 and 70 together which is 110 and then you would subtract 360 from 110 and you answer would be 250.

Answer:

x = 125

Step-by-step explanation:

Kindly check the image below

The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )

According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2

( Note that we are not given the direct intercepted arcs  of x. We are given the intercepted arcs of x's supplementary angle )

That being said we need to find x's supplement in order to find x

Using the image below as a reference

x's supplement = [tex]\frac{70+40}{2}[/tex]

[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]

So x's supplement = 55

Now to find x

Remember that supplementary angles have a sum of 180°

That being said we can find the missing angle (x) by subtracting the given angle (55) from 180

so x = 180 - 55

180 - 55 = 125

Hence x = 125

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

Given that, the measurement of the tile = 27/4 inches

Side of the drawing = 1/4 inches

The scale of the drawing =

1/4 inch of drawing = 27/4 inch of tile

That means, 1 inch of the drawing = 27 inch of the tile

Therefore,

Answer:

-25 and 4

Step-by-step explanation:

Two numbers that multiply to the value on top and add to the value on bottom

Value on top = -100

Value at bottom = -25

Numbers that multiply to give -100 = -10 × 10, -20 × 5, -25 × 4, - 50 × 2,

Of all the above, - 25 × 4 = -100

-25 + 4 = -21

Value at bottom = -25

Therefore, the two numbers are -25 and 4

-25 × 4 = -100

-25 + 4 = -21
