then multiply by -5

w/-5=10

  x5  x5

w=-50

I'm still really bad at explaining... I'm sry but hope this helps...

Find the dividend if quotient is x–3, remainder is 7x–9 and divisor is x^2-2​
Elza [17]

Answer:

\implies Dividend = x^3-3x^2+4x-3

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Quotient is x–3, remainder is 7x–9 and divisor is x^2-2 .

And we need to find out the Dividend. We know that ,

\implies Dividend = Quotient\times Divisor + Remainder

<u>Substituting</u><u> the</u><u> </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>

\implies Dividend = (x-3)(x^2-2)+7x-9 \\\\\implies Dividend = x^3-2x-3x^2+6+7x-9 \\\\\implies Dividend = x^3-3x^2+4x-3

Michael and Derrick each completed a separate proof to show that corresponding angles AKG and ELK are congruent. Who completed t
lora16 [44]

When completing the proof to show that corresponding angles AKG and ELK are congruent, Michael completed the proof wrongly.

<h3>What are corresponding angles?</h3>

It should be noted that corresponding angles are the angles that occupy the same relative position at each intersection.

From the information, when completing the proof to show that corresponding angles AKG and ELK are congruent, Michael completed the proof wrongly because the second statement shows that they're not Al vertically angles.

The owner of a coffee shop, an amateur statistician, advertises that the price of coffee on any given day will be randomly picke
Musya8 [376]

Answer:

If a customer buys a cup of coffee, 0.067 is the probability that he will pay at least $1.50.    

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $1.35

Standard Deviation, σ = $0.10

We are given that the distribution of  price of coffee is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

a) P(customer will pay at least $1.50)

P(x \geq 1.50)

P( x \geq 1.50) = P( z \geq \displaystyle\frac{1.50 - 1.35}{0.10}) = P(z \geq 1.5)

= 1 - P(z < 1.5)

Calculation the value from standard normal z table, we have,  

P(x \geq 1.50) = 1 - 0.933 = 0.067 = 6.7\%

Hence, if a customer buys a cup of coffee, 0.067 is the probability that he will pay at least $1.50.
