Enter your answer in the box.

Do not use decimals in your answer.

Answers

Answer: 14x+74

Step-by-step explanation:

-6x+86-32x-12+52x=14x+74

-6x+86-32x-12+52x

=-6x-32x+52x+86-12

=14x+86-12

=14x+74

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The final expression after simplifying is 14x + 74.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x + 4 = 3 is an expression.

3 + 4x - 5 is an expression.

We have,

-6x + 86 - 32x - 12 + 52x

Add like terms.

-6x - 32x + 52x = 14x

Now,

14x + 86 - 12

14x + 74

Thus,

The final expression after simplifying is 14x + 74.

Consider 4 flips of an unfair coin where probability of heads is 0.40. Consider all tosses independent of each other. (a) Compare the probability of 4 heads in 4 tosses and 4 tails in 4 tosses. (b) Determine the probability of H T H T in 4 tosses. (c) Determine the number of outcomes that give us 2 heads in 4 tosses in any order. What is the probability of 2 heads in 4 tosses (use (b) and the number of outcomes)

Answers

Answer:

a) 0.0256 = 2.56% probability of 4 heads.

0.1296 = 12.96% probability of 4 tails.

b) The probability is 0.0576 = 5.76%.

c) 6 outcomes given 2 heads in 4 tosses. 0.3456 = 34.56% probability of 2 heads in 4 tosses

Step-by-step explanation:

For each throw, we have these following probabilities:

0.4 = 40% probability of heads.

0.6 = 60% probability of tails.

(a) Compare the probability of 4 heads in 4 tosses and 4 tails in 4 tosses.

4 heads:

4 throws, each with 0.4 probability of heads. So

[tex](0.4)^4 = 0.0256[/tex]

0.0256 = 2.56% probability of 4 heads.

4 tails:

4 throws, each with 0.6 probability of tails. So

[tex](0.6)^4 = 0.1296[/tex]

0.1296 = 12.96% probability of 4 tails.

(b) Determine the probability of H T H T in 4 tosses.

H = 0.4, T = 0.6. So

[tex]p = 0.4*0.6*0.4*0.6 = 0.0576[/tex]

The probability is 0.0576 = 5.76%.

(c) Determine the number of outcomes that give us 2 heads in 4 tosses in any order. What is the probability of 2 heads in 4 tosses (use (b) and the number of outcomes)

Number of outcomes:

The possible outcomes are:

H - H - T - T

H - T - H - T

H - T - T - H

T - H - H - T

T - H - T - H

T - T - H - H

6 outcomes given 2 heads in 4 tosses.

Each with probability 0.0576, as found in b)

6*0.0576 = 0.3456

0.3456 = 34.56% probability of 2 heads in 4 tosses

Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by - 7x + 2y = 14?

Answers

Answer:

y = -2/7x - 27/7

Step-by-step explanation:

first find the slope of the line -7x + 2y = 14 by solving for 'y'

2y = 7x + 14

y = 7/2x + 7

since the slope is 7/2 then the line that is perpendicular will need the opposite and reciprocal of 7/2 which is -2/7

knowing the slope ('m') and having the point (4, -5) we can find the y-intercept of the new line ('b')

y = mx + b

-5 = (-2/7)(4) + b

-5 = -8/7 + b

[change -5 into -35/7]

-35/7 + 8/7 = b

b = -27/7

put 'm' and 'b' into y = mx + b

y = -2/7x - 27/7

The deminsions of a rectangler prism are 5cm, 6cm, and Xcm. Its surface area is 148 cm2. Find the other deminsion.​

Answers

Answer:

The other dimension is x=4 cm

Step-by-step explanation:

Surface Area of a Rectangular Prism

Given a rectangular prism of dimension x, y, and z. Its surface area is calculated with the formula:

A = 2(xy + yz + xz)

We are given the dimensions y=5 cm and z=6 cm. We also have A=148 cm2. Substituting:

148 = 2(x*5 + 5*6 + x*6)

Dividing by 2:

74 = x*5 + 5*6 + x*6

Operating:

74 = 5x + 30 + 6x

Simplifying:

74 = 11x + 30

Subtracting 30:

44 = 11x

Dividing by 11:

x = 4 cm

The other dimension is x=4 cm
