it should be

Answer:

The answer is 2/7.

Step-by-step explanation:

If you flip a coin 7 times then 7 is the denominator, which stands for the total amount of times you flipped the coin. The numerator is 2, which is the amount of times you land on the same thing, in this case, landing on tails.

-Luna

4 right angles

90 + 90 + 90 + 90 = 360

However, it that figure is a circle-- it may include 0 right angles since circles have no angles.

Answer:

Options C and D

Step-by-step explanation:

From the graph attached,

Coordinates of the vertices,

X → (0, 0)

Y → (-1, -2)

Z → (0, -2)

Rule for the rotation of a  point (h, k) by 180° about the origin is given by,

(h, k) → (-h, -k)

By this rule,

Coordinates of the image points will be,

X(0, 0) → X'(0, 0)

Y(-1, -2) → Y'(1, 2)

Z(0, -2) → Z'(0, 2)

Therefore, Option (C) and Option (D) are the correct options.

Answer:

x < - 3

Step-by-step explanation:

Given the inequality :

-3x + 6 < 15

Collect like terms :

-3x < 15 - 6

-3x < 9

Divide both sides by - 3

-3x / 3 < 9/3

x < - 3 (sign changes as we have divides by a negative)

Answer:

10% of espressos sold are single shot espressos.

Step-by-step explanation:

Single shot espressos, as percentage of total espressos sold =

[ Single espressos / Total ( ie Single + Double shot) ] x 100

[ 2 / (2 + 18) ] x 100

(2 / 20) x 100

= 10%

Step-by-step explanation:

start at -1 as your starting point then go down one over 2

Answer:

Subtract 22 from both sides of the equation.

x=-2

Answer:

x = -2

Just move the 2 to the other side. Remember to switch the sign.

Given:

The quadratic equation is :

[tex]16x^2-20x-6=0[/tex]

To find:

The quadratic formula for the given equation after substituting the values.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]16x^2-20x-6=0[/tex]

In this equation, [tex]a=16,b=-20,c=-6[/tex].

Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get

[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]

Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].

The difference between the flat fees of the two companies is $20

Answer:

$87.12

Step-by-step explanation:

To mark up the price you are basically doing 45.85×190%.

If you take a percentage and make it a normal number you need to divide by 100.

190÷100= 1.9

So you multiply 45.85×1.9=87.115

Because this is money you cant have $87 and 11 and a half cents. So you need to round

You need to round up because it is 5, which means that you get $87.12

Step-by-step explanation:

304

plug 4 in for x

3(4)^2 + 4(4)^3 = 304

48 + 256 = 304

Answer: The percent of red lights last between  2.5 and 3.5 minutes = 95.44% approx.

Step-by-step explanation:

Given: Mean time = 3 minutes

standard deviation = 0.25 minutes

The probability of red lights last between  2.5 and 3.5 minutes :-

[tex]P(2.5<x<3.5)\\\\=P(\dfrac{2.5-3}{0.25}<\dfrac{x-\mu}{\sigma}<\dfrac{3.5-3}{0.25})\\\\=P(-2<z<2)\\\\=2P(Z<2)-1\\\\=2(0.9772)-1\\\\=0.9544[/tex]

The percent of red lights last between  2.5 and 3.5 minutes = 95.44% approx.

Answer:

x = 8

Step-by-step explanation:

16 is the same as 2^4

(2^4)³ = 2^3/2x

2^12 = 2^3/2x

as long as bases are both the same then set exponents equal

12 = [tex]\frac{3}{2}[/tex]x

3x = 24

x = 8

Answer:

The answer that is not true when x = -4 is B.

Step-by-step explanation:

Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.

A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.

Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.

Finally D. -4/4 divided equals -1, so that would make it -1 = -1.

B is the only one that doesn't make sense, therefore you have your answer.

Answer:

x = 53

Step-by-step explanation:

x = 53 because they are alternate exterior angles

Answer:

Yes

Step-by-step explanation:

If a triangle follows the Pythagorean theorem, then it is right. The Pythagorean theorem states the following,

[tex]a^2 + b^2 = c^2[/tex]

Where (a) and (b) are the legs or sides adjacent to the right angle of the right triangle, and (c) is the hypotenuse, side opposite the right angle, the longest side.

Substitute in the given values and solve,

[tex](6)^2 + (8)^2 = (10)^2\\\\36 + 64 = 100\\\\100 = 100[/tex]

The given side lengths form a right triangle.
