Answer:

120 degrees. Hope this helps

Step-by-step explanation:

We know the sum of all the angles in a quadilateral is equal to 360. so,

it would be: 360 - (55+65+120)

= 360 - 240

= 120 degrees

Change to standard form 9.071x10^-6

This is Scientific Notation right?
OK
So when the exponent over then is a negative number, that means the decimal point is jumping to the left to make the number smaller

Harper is knitting a scarf for her cousin's birthday. She plans to knit every night, making the scarf 5 centimeters longer each

MissTica

The equation that shows the relationship between x and y is:

y = 5x

A linear equation is in the form:

y = mx + b

where m is the rate of change and b is the initial value of y, y, x are variables.

Let x represent the number of nights knitting and y represent the length of the scarf.

The equation that shows the relationship between x and y is:

y = 5x

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?

bezimeni [28]

Answer:

t = - 24

Step-by-step explanation:

Given t varies inversely as a then the equation relating them is

t = $\frac{k}{a}$ ← k is the constant of variation

To find k use the condition t = 2 when a = - 4

2 = $\frac{k}{-4}$ ( multiply both sides by - 4 )

- 8 = k

t = $\frac{-8}{a}$ ← equation of variation

When a = $\frac{1}{3}$ , then

t = $\frac{-8}{\frac{1}{3} }$ = - 24

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
