Step-by-step explanation:

Andy claims that his bird can do single-digit multiplication. He shows the bird 12 cards with simple multiplication problems that are either correct or incorrect. The bird correctly identifies the correctness of the card 9 times out of 12. If the bird were simply guessing, how many would the bird be expected to get correct? (1 point)

3
9
6
12

Answers

If the bird were just guessing there would be two options (right or wrong) and we would expect them to be equally likely to occur (50% chance for each). A 50% of correct, out of 12 cards gives us:

12×0.50=6

If the bird was guessing we would expect 6 correct answers. (1/2 of the total correct and 1/2 wrong.)

So the answer would be 6.

Answer:

D'G' = 52.5 units

Step-by-step explanation:

Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5

D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )

G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )

Calculate D'G' using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)

D'G' = [tex]\sqrt{(-28-3.5)^2+(-17.5-24.5)^2}[/tex]

       = [tex]\sqrt{(-31.5)^2+42^2}[/tex]

       = [tex]\sqrt{992.25+1764}[/tex]

        = [tex]\sqrt{2756.25}[/tex]

Door tickets (d) are each worth $10: represented in the equation as 10d.

They sold 345 tickets, so p+d=345. They collected $2550, so 7p+10d=2550.

Laura makes $9 per hour working at Starbucks. She can also expect to make an additional $3 in tips for one day. It
costs Laura $48 to fill up her car with gas. What is the minimum number of hours she needs to work in a day to
make $48?

Answers

Answer:

5 Hours

9×5 = 45

plus the $3 tip is 48.

hope this helped:))

Laura needs to work 5 hour in a day to make $48.

What is Unitary Method?

'The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.'

According to the given problem,

Amount Laura makes per hour = $9

Amount Laura receives as tip = $3

Amount Laura needs to fill up her car with gas = $48

Since, 45 is the closest multiple of 9 to 48,

Let, the number of hours Laura has to work be x,

⇒ 9x = 45

⇒ x = 45/9

⇒ x = 5

Since, she will receive an additional tip of $3,

= $( 45 + 3 )

= $48

Hence, we can conclude, Laura has to work a minimum of 5 hours to make $48.
