Answer:
a) Standard deviation: 3 bluberries
b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.
Step-by-step explanation:
We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.
a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:
- 99.7% of the data will fall between 3 standard deviations from the mean.
Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:
Answer:
Step-by-step explanation:
Do you means this
2*2² = 2 ³
Answer: 30%
Step-by-step explanation:
Given: Cupcakes have sprinkles = 15
Cupcakes didn't have sprinkles = 35
Total cupcakes = 15+35 = 50
The percentage of the cupcakes had sprinkles =
Hence, the percentage of the cupcakes had sprinkles = 30%
Answer:
-4
Step-by-step explanation:
2x + 3y = -14
x - y = 3
Multiply the second equation by -2 to eliminate x
2x + 3y = -14
-2x +2 y = -6
-----------------------
5y = -20
Divide by 5
5y/5 = -20/5
y = -4
I'm a 15 yr old 10th grader. I see myself working for nasa one day. I love astronomy and it is what i live for.
Light travels at 1.86x10 to the 5th in another word 1.86000 ( 186k ). The planet is 32,000,000 miles away ( 32 million miles ) 32 million divide by 186k = <span>172.043010753
There is your answer. IT WILL TAKE LIGHT </span><span>172.043010753 ( YOU CAN ROUND IT UP ) SECONDS TO REACH THE PLANET.
I hope it helped you out. You can contact me on instagram ( nymul_yt ) and let me know if you got it or get it right. I will try to answer all of your astronomy question. Me and my friend love astronomy. Astronomy is what we live for.</span>
