Answer:

y = 2/5x - 3

P (0,5)

parallel lines have equal slopes

slope intercept form of an equation

y = mx + b

m = slope, b = y-intercept

parallel to y = 2/5x - 3,

and through P(0, 5)

m = 2/5

y intercept = 5

so, the equation would be

D. y = 2/5x + 5

f a seed is planted, it has a 85% chance of growing into a healthy plant. If 9 seeds are planted, what is the probability that e

The probability that exactly 1 doesn't grow will be 0.07

<h3> What is Probability?</h3>

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15

Using the Bernoulli approximation:

P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵

P(n=1)=9x0.15¹.⁵x0.8⁸.⁵

P(n=1)=0.07

Hence the probability that exactly 1 doesn't grow will be 0.07

Susan has been on a bowling team for 14 years. After examining all of her scores over that period of time, she finds that they f
elixir [45]

Answer:

Step-by-step explanation:

Let X be the random variable that represents a score of Susan. We know that X has a normal distribution with average score of 225 and a standard deviation of 13. For n = 16 games, the average score \bar{X} has a normal distribution with mean of 225 and a standard deviation of 13/\sqrt{16}=13/4=3.25. Besides, the z-score related to 220 is (220-225)/3.25=-1.5385, and the z-score related to 228 is (228-225)/3.25= 0.9231. Therefore, we are looking the probability P(220 < \bar{X} < 228) = P(-1.5385 < Z < 0.9231) = P(Z < 0.9231) - P(Z < -1.5385) = 0.76

Answer:

The slope is

The y-intercept is

−

Explanation:

5

is the standard form for a linear equation. The slope-intercept form is

y

=

m

x

+

b

, where

m

is the slope, and

b

is the y-intercept. To convert from standard form to slope-intercept form, solve the standard form for

y

.
