Answer:
y = -2x + 1
Step-by-step explanation:
First, find the slope with rise/run (y2 - y1) / (x2 - x1)
We can use the points (-1, 3) and (0, 1)
Plug in the points:
(1 - 3) / (0 + 1)
-2/1
= -2
The y-intercept is (0, 1) because that is the point where the line intercepts the y axis. So, we can plug in the slope and y-intercept into the equation:
y = mx + b
y = -2x + 1
The standard deviation for the number of seeds germinating in each batch is 1.3
<u>Solution:</u>
<em><u>In binomial distribution, standard deviation is given as:</u></em>
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
<em><u>Then, the standard deviation for the number of seeds germinating in each batch.</u></em>
Plugging in values in formula, we get
Therefore the standard deviation for the number of seeds germinating in each batch is 1.3
Answer:
3×2 + 3×-b
Step-by-step explanation:
Answer:
Step-by-step explanation:
That means that the number must end in 2 or 8 to be divisible by 2.
Because the number must be between 7000 and 8000 the only number it can start with is 7
With those clues in mind, we can write
1 * 2 * 1 * 2. It doesn't say if we can use a number more than once. I am assuming not. We should get 4
7 2 5 8
7 5 2 8
7 5 8 2
7 8 5 2
Answer: She now has $64 in the bank.
Step-by-step explanation:
Amount of money in bank account = $54
amount refunded by a store = $10
Total amount of money in bank =Amount of money in bank account + amount refunded by a store= $54+ $10 =$64
