what can you tell about the mean of eachdistribution
Answer:
In a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together, giving. .

what is the reactants and products of Fe2O3+3CO→2Fe+3CO2
Step-by-step explanation:
The compounds that are found on the left of a chemical reaction (the side with the arrow's tail) are the reactants. Therefore our reactants are Iron(III) oxide and Carbon monoxide.
The compounds found on the right-hand side of a chemical reaction/after the arrow are the products. Therefore our products are Iron and Carbon dioxide.
Answer:
[tex]\large \boxed{\sf Reactants \rightarrow Fe_2O_3, \ CO}[/tex]
[tex]\large \boxed{\sf Products \rightarrow Fe, \ CO_2}[/tex]
Step-by-step explanation:
The substance(s) to the left of the arrow are called reactants
The substance(s) to the right of the arrow are called products

You have $500 in a savings account. How long will it take to double that
amount at an 8% annual interest rate?
Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000
If anyone is good at right triangle trig word problems please help
Answer:
The height of the hill is 131ft
See explanation in the photo
Answer:
91 feetStep-by-step explanation:
Refer to attached picture
Let the base is b and the height of the hill is x.
For the smaller triangle we have:
x/b = tan 39.3°And for the bigger triangle:
(x + 40)/b = tan 49.7°Solve both equations for b:
b = x/ tan 39.3°b = (x + 40)/tan 49.7°Eliminate b and get the values of tan, solve for x:
x/ tan 39.3° = (x + 40) / tan 49.7°x tan 49.7° = (x + 40) tan 39.3°x( 1.179) = x(0.819) + 40(0.819)x(1.179 - 0.819) = 32.76x = 32.76/0.36x = 91 feet (rounded to the nearest foot)Help[tex]\frac{\sqrt[3]{175} }{\sqrt[3]{50} }[/tex]

A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?
Answer: 3/8.
Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.
Answer:
3/28Step-by-step explanation:
Total number of cartons:
2 + 3 + 3 = 8Let cm be the chocolate milk, there are 3 cartons of cm.
The probability of the first pull of cm is:
P(cm) = 3/8Then we have 7 total left and 2 cm.
The probability of the second cm is:
P(cm) = 2/7Now the probability of the two pulls:
P(cm and cm) = 3/8*2/7 = 3/28Help pls btw I will give brainly
Answer:
[tex]\frac{3}{8}[/tex] feet²
Step-by-step explanation:
The area ( A) is calculated as
A = length × width

Your class wants to raise more than $350 for the Freshman Party and you choose to sell candy and cookies to accomplish this task. You earn $6 on each basket of candy, b, and $3 on each box of cookies, c, that you sell. If the number of boxes of cookies sold is 78, at least how many baskets of candy will you need to sell to reach your goal?
Answer:
16 baskets of candy.
Step-by-step explanation:
78 boxes of cookies times $3 per box equals $234.
$350-$234=$116 left you need to make so-
each basket of candy earns $6, divide $116 by $6 to equal 56.
You will need to sell 56 baskets of candy at $6 each to reach your goal of $350 .
