Answer:

The answer is option D: the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.

Step-by-step explanation:

The normal bid is $0.40 and the bid multiplier is 75%.

This amount becomes:

0.40+(0.75\times0.40)

= $0.70  (OPTION D)

So, the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.

Find the exact roots of x²-2x-10=4x​
BARSIC [14]

Answer:

x =  3 -  \sqrt{19}  \:  \: or \:  \: x = 3 +   \sqrt{19}

Step-by-step explanation:

The given equation is

{x}^{2}  - 2x - 10 = 4x

We group the linear terms to get:

{x}^{2}  - 2x - 4x - 10 = 0

{x}^{2}  - 6x - 10 = 0

We compare to

a {x}^{2}  + bx + c = 0

This means

a=1, b=-6 and c=-10

We plug in the values into the quadratic formula:

x =  \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}

This gives us

x =  \frac{ - -6 \pm \sqrt{ {( - 6)}^{2} - 4 \times 1 \times  - 10 } }{2 \times 1}

x =  \frac{ 6 \pm \sqrt{ 36 + 40 } }{2}

x =  \frac{ 6 \pm \sqrt{76 } }{2}

x =  \frac{ - 6 \pm 2\sqrt{19} }{2}

x = 3 \pm \sqrt{19}

The solutions are

x =3 +  \sqrt{19}

or

x = 3 -  \sqrt{19}

Can someone explain the snake method, I don't understand how to do it
storchak [24]

Answer:

  • x ∈ [−2; 1] ∪ 3.5

Step-by-step explanation:

<h3>Given</h3>

<u>Inequality</u>: (x-1)(x+2)(2x-7)≤0

<h3>Solution: </h3>

<u>If we solve the corresponding equation (x-1)(x+2)(2x-7)²= 0, we get roots </u>

  • x =  -2, 1, 3.5

<u>We need to consider the following 4 intervals: </u>

  • (−∞; −2), [−2; 1], (1; 3.5), (3.5; ∞)

<u>1st interval</u> (−∞; −2)

  • The expression (x-1)(x+2)(2x-7)² is positive as two of the multiples are negative and one is always positive (square number), and therefore  does not satisfy the inequality.

<u>2nd interval</u>  [−2; 1]

  • The expression is negative as only one of the multiples is negative, and therefore the interval (−1; 2) satisfies the inequality.

<u>3rd interval</u> (1; 3.5)

  • The expression is positive as all the multiples are positive. Therefore, the interval (1; 3.5) also does not satisfy the inequality.

<u>4th interval</u>

  • The expression is positive as above, and therefore also does not satisfy the inequality.  

<u>So, the answer to the inequality is: </u>

  • x ∈ [−2; 1] ∪ 3.5

The two-way table shows the number of houses on the market in the Castillos’ price range. A 6-column table has 4 rows. The first
zmey [24]

Answer:

The probability is 0.8

Step-by-step explanation:

  • if u see the table clearly, there are 30 houses in total with 2 bathrooms.
  • by the general definition of probability,

probability of an event P =\frac{Number of desirable observations}{total number of observations}

  • so, here 30 will be the denominator in the above formula(by definition).
  • from the table, in the 3rd column and 2nd row (desirable box) i.e, the one which represents 2 bathrooms and 3 bedrooms, has the entry as 24.
  • so, the numerator for above given formula will now become 24.

therefore probability P=\frac{24}{30} =\frac{8}{10} =0.8

  • So, the probability is 0.8.
