Part A:
If 25% is dark chocolate and the rest is milk chocolate then, dark + milk = all
25% + milk chocolate= 100%
Subtract 25% from both sides and 100 minus 25 is 75 so, milk chocolate is 75% of all the chocolate.
Now, if there is 3 pounds of milk chocolate then 3 pounds= 75%.
You would divide by 3 so, 75 divided by 3 is 25.
1 pound or lb= 25% which us the amount of dark chocolate that there is.
Now, we know that there milk chocolate is 75% and dark chocolate is 25% of all the chocolate.
M= pounds of milk chocolate
D= dark chocolate
Equation: m divided by d or m/d= 75 divided by 25 or 75/25 or m/d=3 and m=3
3 divided by d or 3/d=3
3=3d
D=1
Part B:
There is 1 pound of dark chocolate in the candy.
Hope this helps! :)
Whats the question? its not there
Answer:
5
Step-by-step explanation:
(a + (1/a)2 = a2 + (1/a2) + 2
⇒ (a + (1/a))2 = 23 + 2
⇒ (a + (1/a))2 = 25
⇒ a + (1/a) =
⇒ a + (1/a) = 5
a3+b3=
(a+b)
(a2−ab+b2)
where a=a
and b=1/a.
so sum it up u get -1
Jenna wants to convert a decimal number to its octal form.
The octal numeral system is the base-8 number system, and it uses the digits 0 to 7.
To convert the given decimal number into the octal form, we have to divide the given decimal number by 8 to get its octal form as the base value of the octal number is 8.
Therefore, the complete statement is:
"In the octal number system, you need to divide a number by the base value 8 ".
Recall that the mean of a given set of numbers is the sum of the numbers divided by the number of numbers, therefore, the mean of the dataset is:
Now, the range of a data set is the difference between the maximum and the minimum, in this case, the maximum is 99, and the minimum is 15 therefore, the range is:
Finally, the standard deviation is given by the following formula:
where N is the sample size, x_i is an element of the set, and x^- is the mean. The standard deviation of the set is:
