Exponential because the data is not increasing at a constant rate

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

FIND Y IN XYZ, help please

kumpel [21]

Given:

In triangle $XYZ,m\angle X=90^\circ, m\angle Y=45^\circ, m\angle Z=45^\circ, XZ=y,YZ=15\sqrt{2}$ .

To find:

The value of y.

Solution:

In a right angle triangle,

$\sin \theta =\dfrac{Perpendicular}{Hypotenuse}$

Using the above ratio for the triangle XYZ, we get

$\sin Y =\dfrac{XZ}{YZ}$

$\sin 45^\circ =\dfrac{y}{15\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{y}{15\sqrt{2}}$

$\dfrac{15\sqrt{2}}{\sqrt{2}}=y$

$15=y$

Therefore, the correct option is C.
