Answer:

Step-by-step explanation:

90° counterclockwise rotation: (x,y) becomes (-y,x). so it would be on the upper left square. R would be the farthest to the left with S on top and T to the right. Also the triangle isn't even the same size in the picture. T should be a unit up.

Department started out with 100 pencils and 200 pens during the lat quarter of this year they lost 4% of the pens and 2% of the

o-na [289]

Answer:

The remaining number of the pencil = 98

The remaining number of the pens = 192

Step-by-step explanation:

Here, according to the question:

The number of pencils at the starting at the quarter = 100

The percentage of the lost pencil over the year = 2%

Now, calculating the lost pencil, we get:

2% of 100 = $\frac{2}{100} \times 100 = 2$

⇒The number of lost pencil over the year = 2

So,Number of remaining Pencil = Total pencil - Number of pencil lost

= 100 - 2 = 98

The number of pens at the starting at the quarter = 200

The percentage of the lost pens over the year = 4%

Now, calculating the lost pens, we get:

4% of 200 = $\frac{4}{100} \times 200 = 8$

⇒The number of lost pens over the year = 8

So,Number of remaining Pens = Total pens - Number of pens lost

= 200 - 8 = 192

Hence, the remaining number of the pencil = 98

And and the remaining number of the pens at the end of the year = 192

Roman and Ranjan each divided 3.56 by 0.72. Roman got 4.94 for his quotient. Which student divided correctly? How do you know? E

Dmitriy789 [7]

Let's concentrate on the math, please, and not on "no scamming me."

Any number other than zero, if divided by a number between 0 and 1, results in a larger number.

Thus, 3.56 divided by 0.72 results in a number larger than 3.56. Thus, at first glance, 4.94 seems quite reasonable as the answer here.

Could you use long division to find the actual quotient?

You could multiply both 3.56 and 0.72 by 100 to get rid of the decimal points. Then you'd be dividing 72 into 356.

Can you do that on paper?

Can you do that using a calculator?

Is the result equal to 4.94?

You have not shared what result Ranjan got, so it's hard to judge which student got the correct result. Perhaps both did!

When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 49 b

Brilliant_brown [7]

Answer:

Step-by-step explanation:

Given that A shipment contains 6000 batteries, and 1% of them do not meet specifications.

Sample size =49

If x is the number of batteries not meeting specifications then

x is binomial with n =49 and p = 0.01

Because i) each toy is independent of the other

ii) There are only two outcomes

Probability whole shipment is accepted = Prob (X≤3)

=0.9885

Hence almost all shipments would be accepted.
