Answer:

C) 0.71.

Step-by-step explanation:

To find the probability of an event occurring, we need to sum up all the probabilities of the outcomes that satisfy the event. In this case, the event "F or C" is satisfied by all the outcomes in which the participant's first motor vehicle had four cylinders or was a car.

We can see from the table that 118 out of the 200 participants had their first motor vehicle as a car, so the probability of this event occurring is 118/200 = 0.59. Similarly, we can see that the probability of the event "first motor vehicle had four cylinders" occurring is (118 + 4) / 200 = 0.62.

Therefore, the probability of the event "F or C" occurring is the sum of the probabilities of these two events occurring, which is 0.59 + 0.62 = 0.71. The correct answer is therefore C) 0.71.

The value of the probability P(F or C) is 0.80, Option D is correct.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a survey participant is randomly selected.

Let F be the event that the participant’s first motor vehicle had four cylinders and

let C be the event that the participant’s first motor vehicle was a car.

We need to find the value of P(F or C)

The number of P or c is 118+6+18+16+2

=160

The number of people in total are 200.

P(F or C )= 160/200

=0.80

Hence, the value of the probability P(F or C) is 0.80, Option D is correct.

Answer:

19.5 in.

Step-by-step explanation:

Let the width = x.

The length is 3 more than the width, so the length is x + 3.

perimeter = 2 * length + 2 * width

perimeter = 2(x + 3) + 2x

perimeter = 72

2(x + 3) + 2x = 72

2x + 6 + 2x = 72

4x + 6 = 72

4x = 66

x = 16.5

x + 3 = 16.5 + 3 = 19.5

Answer: 19.5 in.

The number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Step-by-step explanation:

We need to find the number of turns the graph of [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] have?

Turns of graph:

The graphs turns when it changes from increasing to decreasing (rise to fall) or decreasing from increasing (fall to rise)

Turns of graph for a polynomial

A polynomial having degree n will have maximum n-1 turns.

So, for the given polynomial

[tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex]

We need to find degree

The highest exponent of the polynomial is the degree of polynomial

So, Degree n = 5

Number of turns = n - 1 = 5-1 =4

So, the number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Step-by-step explanation:

Here, we want to express the given polynomial in the given form while giving the values of a and b

We can rewrite the polynomial as follows;

x^2 + 6x + 9 + 4

We can factorize the first part;

x^2 + 3x + 3x + 9 + 4

x(x + 3)+ 3(x + 3) + 4

= (x + 3)(x + 3) + 4

The final cost of ice-cream container is: 2.09 dollars

Step-by-step explanation:

In order to find the price of an item after adding tax the tax is found on the price of the item and then added to the cost.

Given

Price of ice cream container = $1.99

Tax Rate = 4.75%

The amount of tax t will be:

[tex]t = 4.75\%\ of\ 1.99\\= 0.0475*1.99\\=0.094525[/tex]

Rounding off to nearest hundredth

t = 0.10

The final cost is given by:

[tex]Final\ cost = Cost + tax\\= 1.99+0.10\\=2.09[/tex]

Hence,

The final cost of ice-cream container is: 2.09 dollars

Given:

The expression is

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

To find:

The factors of the given expression.

Solution:

We have,

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

First taking [tex](2x-6)[/tex] common, the given expression can be written as

[tex]=(2x-6)(x^3+x^2)[/tex]

Taking [tex]x^2[/tex] common from [tex](x^3+x^2)[/tex], we get

[tex]=x^2(2x-6)(x+1)[/tex]

Therefore, the factors of the given expression are [tex]x^2(2x-6)(x+1)[/tex].

Answer:

They contributed $8

Step-by-step explanation:

Given

[tex]Savings = \$40[/tex]

Proportion of savings: [tex]Parent = \$1[/tex]   [tex]You = \$4[/tex]

Required

Determine your parent contribution

From the question, we understand that, they contribute $1 when you save $1.

This means that the unit savings is:

[tex]Unit = \$4 + \$1[/tex]

[tex]Unit = \$5[/tex]

The parent contribution is then calculated as:

[tex]\frac{Parent\ Proportion}{Unit\ Savings} * Total\ Savings[/tex]

[tex]= \frac{\$1}{\$5} * \$40[/tex]

[tex]= \frac{1}{5} * \$40[/tex]

[tex]= \frac{1* \$40}{5}[/tex]

[tex]= \frac{\$40}{5}[/tex]

[tex]= \$8[/tex]

Hence, they have contributed $8
