A) L +6 = 2W  OR

A) L +6 -2W = 0

B) 2L + 2W = 312  Adding A and B

3L +6 = 312

3L = 306

Length = 102

A) 102 +6 = 2W

108 = 2W

Width = 54

Answer:

Step-by-step explanation:

From the figure attached,

Point B has been dilated to form point B'.

B(3, 1) → B'(6, 2)

          → B'[(2 × 3), (2 × 1)]

Since rule for the dilation of a point (x, y) by a factor of k is,

B(x, y) → B'(kx, ky)

By comparing the coordinates k = 2 is the scale factor by which the point B has been dilated about the origin.

Therefore, other vertices of the quadrilateral will be,

A(-2, 3) → A'(-4, 6)

C(1, -1) → C'(2, -2)

D(-3, -2) → D'(-6, -4)

A walk-in medical clinic believes that arrivals are uniformly distributed over weekdays (Monday through Friday). It has collecte
allsm [11]

Answer:

The degrees of freedom are given by;

df =n-1= 5-1=4

The significance level is 0.1 so then the critical value would be given by:

F_{cric}= 7.779

If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays

Step-by-step explanation:

For this case we have the following observed values:

Mon 25 Tue 22 Wed 19 Thu 18 Fri 16 Total 100

For this case the expected values for each day are assumed:

E_i = \frac{100}{5}= 20

The statsitic would be given by:

\chi^2 = \sum_{i=1}^n \frac{(O_i-E_i)^2}{E_i}

Where O represent the observed values and E the expected values

The degrees of freedom are given by;

df =n-1= 5-1=4

The significance level is 0.1 so then the critical value would be given by:

F_{cric}= 7.779

If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays

meriva

Answer:

99

Step-by-step explanation:

1/9 of 72 = 8

1/4 of 72 = 18

1 + 8 = 9

72 + 18 = 90

90 + 9 = 99

Just dividing the volumes of the pan, 189 and one bar, 3, suggests that at most she'll be able to cut 63 bars.

But you'll also have to prove that you can divide it in a regular pattern. And you can:

9 divides by 1

10.5 divides by 1.5

2 divides by 2.

So no incomplete bars!

What TWO ratio is equivalent to 18/6
vampirchik [111]

Answer:

Step-by-step explanation:

6:2

Divide both sides by 3.

18 divided by 3 is 6

Now do the other side

6 divided by 3 is 2

So, 6:2

3:1

Divide both sides by 6

18 divided by 6 is 3

Now do the other side

6 divided by 6 is 1

So, 3:1

9:3

Divide both sides by 2

18 divided by 2 is 9

Now do the other side

6 divide by 2 is 3

So, 9:3

Hope this helped :)
