In a quiz consist of 10 questions,+2 marks are given for a correct answer, -1 marks for an incorrect answer and 0 marks for not attempting a question. Radhika got 8 correct answers and 2 wrong answers. What is her total score?

Answers

Answer:  14

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

Work Shown:

c = number of correct answers

w = number of wrong answers

n = number of questions not attempted

2c = points you get from all the correct answers

-1w = points you get from all the wrong answers

0n = points you get from all the questions attempted

2c-1w+0n = 2c-w = total number of points

In this case, she got 8 correct answers and 2 wrong answers. So c = 8 and w = 2 which leads to

2c-w = 2*8-2 = 16-2 = 14

Her total score is 14.

Write an equation in​ slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
(-3,-3);y=-3x-2 y=−3x+2
Write an equation for the line in​ slope-intercept form.

Answers

Answer:

y = –3x – 6

Step-by-step explanation:

We'll begin by obtaining the slope of the equation y = –3x – 2.

This can be obtained by comparing

y = –3x – 2 with y = mx + c

Thus, the slope (m) of the equation

y = –3x – 2 is –3.

Next, we shall determine the slope of the equation parallel to line with equation y = –3x – 2.

This is illustrated below:

For parallel lines, the slope are related as follow:

m1 = m2

m1 = –3

m2 = m1 = –3.

Finally, we shall determine the equation as follow:

Coordinate = (–3, –3)

x1 coordinate = –3

y1 coordinate = –3

Slope (m) = –3

y –y1 = m(x – x1)

y – (–3) = –3 (x – (–3))

y + 3 = –3 (x + 3)

y + 3 = –3x – 3

Rearrange

y = –3x – 3 – 3

y = –3x – 6

Thus, the equation parallel to the line is y = –3x – 6

What is f(5) for the function f(x) = 6x + 1?

Answers

Answer:

31

Step-by-step explanation:

plug in 5 for x

6(5)+1

30+1

31

A function is a relation that gives one output for every single input thus the value of f(5) for the function will be 31.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given funciton,

f(x) = 6x + 1

At x = 5

f(5) = 6(5) + 1

f(5) = 30 + 1 = 31

Hence "A function is a relation that gives one output for every single input thus the value of f(5) for the function will be 31".

Website A offers tickets to a local charity event for $7.50 each plus a $14.25 handling fee, while Website B offers the tickets for $8.50 plus a $3.25 handling fee. Which equation can be used to determine how many tickets need to be purchased in order for the cost to be the same?

Answers

Answer:

14.25+7.50x=3.25+8.50x

Step-by-step explanation:

From the information given, the equation that can be used to determine how many tickets need to be purchased in order for the cost to be the same would indicate that the price of purchasing tickets on website A would be equal to the price of purchasing tickets on website B, which is:

14.25+7.50x=3.25+8.50x, where x is the number of tickets purchased

14.25-3.25=8.50x-7.50x

According to a Wired magazine article, of e-mails that are received are tracked using software that can tell the e-mail sender when, where, and on what type of device the e-mail was opened (Wired magazine website). Suppose we randomly select received e-mails.

Answers

a.The expected number of emails is 12

b. The variance and the standard deviation is 7.200 and 2.683

Calculation of expected number of emails, variance and standard deviation:

Given that

P = 0.40 and n = 30

a)

The expected value of received e-mails is

= n × p

= 30 × 0.4

= 12  

b)

The variance of emails received is

= n × p × (1 - p)

= 30 × 0.4 × 0.6

= 7.200

Now

The standard deviation of emails received is

= sqrt(variance)

= 2.683

We simply applied the above formula

This is not a multiple choice question. Please help if you know how to do it.

Answers

See attachment for math work and answer.

a) The expression will be zero when x = -4 or 8

b) The trinomial equivalent of the expression is x²  - 4x  -  32

c) The trinomial equals to zero when x = 8

The given expression is (x  - 8)(x  + 4)

a) For what value of x will the expression be equal to zero

(x  - 8)(x  + 4)  =  0

This can  be split into:

x  -  8   =   0

That is,  x  = 8

x  +  4  =  0

That is,  x = -4

The expression (x  - 8)(x  + 4) equals to zero when x = -4 or x = 8

b) Write this product as an equivalent trinomial.

A trinomial is a polynomial expression with three terms

Expand (x - 8)(x + 4)

x² + 4x  - 8x - 32

x²  - 4x  -  32

c) Show that this trinomial is also equal to zero at the larger value of x from part (a)

The larger value of x from part (a) is 8

Substitute x = 8 into x²  - 4x  -  32

8² - 4(8)  -  32

=  64  -  32 - 32

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as,

H² = P² + B²

An old rectangular wedding photo has a diagonal length of 13.6 inches and a height of 12 inches.

Then the width of the photograph is calculated as,

13.6² = 12² + w²

184.96 = 144 + w²

w² = 40.96

w = 6.4 inches

Answer: -30x⁵y⁷

Step-by-step explanation:

When multiplying exponents, you add them.

Distribute the -5x³ and y² to the terms inside of the parentheses to simplify:

-30x⁵y⁷

Hope this helps!

when multiplying variables that are the same but have different exponents, just add the exponents together (ex: x^2*x^5 = x^7)

now that we know that, just multiply everything by it’s like term - coefficient by coefficient, variable by variable

so: (-5*6)(x^3*x^2)(y^5*y^2) = (-30)(x^5)(y^7)

now just combine them: -30x^5y^7

Answers

Answer:

-49/50

Step-by-step explanation:

-39v=4v+7(v+7)

Distribute

-39v = 4v +7v+49

Combine like terms

-39v = 11v+49

Subtract 11 v from each side

-39v-11v = 11v-11v +49

-50v = 49

Divide by -50

-50v/-50 = 49/-50

v = -49/50

Answer:

v= - 49/50

Step-by-step explanation:

-39v=4v+7(v+7)

open the parentheses by multiplying both v&7 by 7:

-39v=4v+7v+49

add like terms:

-39v-4v-7v=49

-50v=49

divide both sides by -50:

v= - 49/50
