Mashcka [7]
The answer is 21

By comparing the 4 vertices you can determine the rectangle x-length and y-length. The coordinate for the vertice is:
1,+4i
-2, +4i
-2, -3i
1, -3i

From the coordinate, you can see there are 2 x coordinate(1 and -2) and 2 y coordinate(4i and -3i) that used.
The x-length would be: 1 - (-2)= 3
The y-length would be: 4i- (-3i)= 7i

Then the area of the rectangle would be:
area= x-length * y-length= 3*7=21

Okay okay okay

Answer:

r = \frac{30}{71}

Step-by-step explanation:

12 - \frac{r}{6} = 5

6 × 12 × r × 6 - \frac{r}{6} = 5 × 6

72r - r = 30

71r = 30

r = 30 ÷ 71

r = \frac{30}{71}

Gnoma [55]

Answer:

The proportion of individuals score at most 74 points on this test is 70%.

Step-by-step explanation:

The complete question is:

Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.

Solution:

Let <em>X</em> represent the scores on a reading ability test.

It is provided that X\sim N(70,8^{2}).

Compute the probability that an individuals score is at most 74 points on this test as follows:

P(X\leq 74)=P(\frac{X-\mu}{\sigma}\leq \frac{74-70}{8})

                 =P(Z

Thus, the proportion of individuals score at most 74 points on this test is 70%.

Answer:

  275

Step-by-step explanation:

Let h represent the number of hamburgers sold. Then the number of cheeseburgers sold is h-62, and the combined total is ...

  hamburgers + cheeseburgers = combined total

  h + (h -62) = 488

  2h = 550 . . . . . . . . add 62, collect terms

  h = 275 . . . . . . . . . .divide by 2

275 hamburgers were sold on Friday.
