Step-by-step explanation:

# Area of painting = 20 × 16

# Area of combination = 25 × 20

.°. Area of frame = Area of combination - Area of painting

= (25×20)-(20×16)

=20 (25-16)

=20 × 9

$= 180 {cm}^{2}$

Problem

Sergeu [11.5K]

The lengths of HJ and JK are 50 and 72 respectively.

Given: J is between H and K. the length of HJ=2x+4, JK=3x+3, and HK=22.

The line HJ and JK are collinear then the total length is given as: HJ+JK=HK

substitute values

⇒ (2x+4)+(3x+3)=22

⇒ 5x+7=22

⇒ 5x=22-7

⇒ 5x=15

⇒ x=3

Thus, the length of HJ is (2x+4)=(2*3+4)=10

And the length of JK is (3x+3)=(3*3+3)=12

$6 \times 3\frac{1}{4} \\ \frac{24}{4} \times \frac{13}{4} = \frac{312}{16} = \frac{39}{2} = 19 \frac{1}{2}$

The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of

Harlamova29_29 [7]

The standard deviation for the number of seeds germinating in each batch is 1.3

Solution:

In binomial distribution, standard deviation is given as:

$\sigma=\sqrt{np(1-p)}$

Where "n" is the number of observations

"p" is probability of getting success

We are given that:

Total batches of seed = 8

Probability that a radish seed will germinate is 0.7

Here success is getting radish seed germinated

Then, the standard deviation for the number of seeds germinating in each batch.

Plugging in values in formula, we get

$\sigma=\sqrt{(8)(0.7)(1-0.7)}\\\\=\sqrt{(8)(0.7)(0.3)}\\\\=\sqrt{1.68}\\\\=1.29614\approx1.3$

Therefore the standard deviation for the number of seeds germinating in each batch is 1.3

Am I doing this right plz help me

Your original inequality is
.. w -2 ≤ 8
The additive property of equality applies to inequalities as well as to equations. You use the additive property of equality to solve this. Add 2 to both sides.
.. w -2 +2 ≤ 8 +2
The purpose of adding 2 is to cancel the effect of subtracting 2. That is, -2+2=0, and w+0 = w.
.. w ≤ 10

The correct selection would be B.
