Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?​

Answer:

x = 4, -4, 7i, -7i

Step-by-step explanation:

(x^2 – 16)(x^2 + 49) = 0

x^2 – 16 = 0 or x^2 + 49 = 0

x^2 = 16 or x^2 = -49  

x = ± 4 or x^2 = ±7√-1  =±7i

Answer:

=5×12÷[-12÷{15+(-9)}]

The expression is 12n

He reads 84 books in 7 months

==================================================

Explanation:

For 1 month, he has read 12*1 = 12 books

For 2 months, he has read 12*2 = 24 books

For 3 months, he has read 12*3 = 36 books

and so on

If we let n represent the number of months, then 12*n or 12n represents the number of books read after n months. The variable n is some placeholder for a positive whole number.

If we replaced n with say n = 7, then 12*n = 12*7 = 84 books are read in 7 months.

Answer:

2nd and 3rd ordered pair are on the graph

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the value obtained is equal to the y- coordinate then it lies on the graph.

(1, 625 )

f(1) = - [tex]25^{1+1}[/tex] = - [tex]25^{2}[/tex] = - 625 ≠ 625 ← No

(0, - 25 )

f(0) = - [tex]25^{0+1}[/tex] = - [tex]25^{1}[/tex] = - 25 ← Yes

(- 1, - 1 )

f(- 1) = - [tex]25^{-1+1}[/tex] = - [tex]25^{0}[/tex] = - 1 ← Yes [ using [tex]a^{0}[/tex] = 1 ]

The number of the ways that can be used to set the digital lock will be 120.

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

Decide if the following scenario involves a permutation or combination. Then the number of possibilities will be

You are setting the combination on a five-digit lock.

You want to use the numbers 12345, but you don't care what order they are in.

Then the number of the ways that can be used to set the digital lock will be

⇒ 5!

⇒ 5 x 4 x 3 x 2 x 1

⇒ 120

The number of the ways that can be used to set the digital lock will be 120.

Answer:

[tex]y=2\sqrt{2}[/tex]

[tex]y\approx 2.82843[/tex]

Step-by-step explanation:

The given triangle is a right triangle, this is indicated by the box around one of the angles in the triangle. The Pythagorean theorem is a property that applies to right triangles, this property comes in the form of an equation, which can be simply put as the following:

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

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

Look at the smallest triangle in the entire image. Using the Pythagorean theorem, one can form an equation and solve for the unknown parameter, (y).

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

Substitute,

[tex](1)^2+(y)^2=(3)^2[/tex]

Simplify,

[tex](1)^2+(y)^2=(3)^2[/tex]

[tex]1+y^2=9[/tex]

[tex]y^2=8[/tex]

[tex]y=\sqrt{8}[/tex]

[tex]y=2\sqrt{2}[/tex]

Answer:

First and Second option choices

Step-by-step Explanation:

1st case:

Initial deposit (P) = 500

Annual interest rate (r) = 2.5%

Account balance after x years, y = P(1+r/100)×

y = 500(1+2.5/100)×

y = 500(1+0.025)×

y = 500(1.025)×

2nd case:

Initial deposit (P) = 400

Annual interest rate (r) = 2%

Account balance after x years, y = P(1+r/100)×

y = 400(1+2/100)×

y = 400(1+0.02)×

y = 400(1.02)×

The correct option is (A) and (B)

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation. Look at the image below to understand the parts of an equation.

Initial deposit (P) = 500

Annual interest rate (r) = 2.5%

Account balance after x years, y = P(1+r/100)^×

y = 500(1+2.5/100^)×

y = 500(1+0.025)^×

y = 500(1.025)^×

again,

Initial deposit (P) = 400

Annual interest rate (r) = 2%

Account balance after x years, y = P(1+r/100)×

y = 400(1+2/100)^×

y = 400(1+0.02)^×

y = 400(1.02)^×

#SPJ2

a right angle is 90°, or 1/4 of a circle.

3/5 * 1/4 = 3/20

radian measure is the length of the circumference of this part of the circle.

a full circumference of a circle would be 2*pi*r, also expressed as 2 rad * r

now let's multiply the full thing with the 3/20 from earlier to just get the desired fraction:

6/20 rad * r

= 3/10 rad * r

of course a solution in cm or inch still depends on the radius here, wich could be just plugged in at will

Answer:

[tex]\frac{3\pi }{10}[/tex]

Step-by-step explanation:

To express degrees in radians

radian measure = degree measure × [tex]\frac{\pi }{180}[/tex]

[tex]\frac{3}{5}[/tex] of a right angle

= [tex]\frac{3}{5}[/tex] × 90° = 54° , then

radian = 54 × [tex]\frac{\pi }{180}[/tex] = [tex]\frac{54}{180}[/tex] × π = [tex]\frac{3}{10}[/tex] × π = [tex]\frac{3\pi }{10}[/tex]

Answer:

39°

Step-by-step explanation:

The angle adjacent to 115° in the lower triangle = 180° - 115° = 65°

angle on circle in lower triangle

= 180° - (65 + 76)°  ← angle sum in triangle

= 180° - 141° = 39°

Angles on the circle subtended from the same arc are congruent, then

shaded angle = 39°

Answer:

156m^2

Step-by-step explanation:

I dont know what you mean by "each figure," but if you need the surface area for the rectangular prism, then the answer is 156, because the top square has a surface area of 3*6, then it equals 18, and the bottom square is the same, so it is also 18, 18*2=36

The 4 rectangle on the side are all the same, and they are all 10x3 which is 30, so 30*4 because there are 4 rectangles, equals 120.

120+36=156. The surface area of the rectangle is 156m^2
