Duncan's Bakery sold one customer 1 dozen chocolate cookies and 10 dozen oatmeal cookies
for $49. The bakery also sold another customer 1 dozen chocolate cookies and 9 dozen
oatmeal cookies for $45. How much do the cookies cost?
A dozen chocolate cookies cost $
and a dozen oatmeal cookies cost $
Answer:
Dozen Oatmeal = $4 and Dozen Chocolate = $9
Step-by-step explanation:
Dozen Oatmeal:
10 dozen oatmeal and 1 dozen chocolate =$49
9 dozen oatmeal and 1 dozen chocolate = $45
The second customer bought 1 less dozen and paid $4 fewer dollars, therefore 1 dozen oatmeal must equal $4
Dozen Chocolate: let C = 1 dozen chocolate
10 dozen oatmeal + 1 dozen chocolate = $49
(10 x $4) + C = $49
$40 + C = $49
-40 -40
C = $9
1 dozen chocolate cookies = $9

given the function f(x)=4-2x: if the domain is -4,0,5 find the range
Answer:
{12, 4, -6}
Step-by-step explanation:
f(x)=4-2x
x = -4
f(-4) = 4 - 2(-4) = 12
x = 0
f(0) = 4 - 2(0) = 4
x = 5
f(5) = 4 - 2(5) = -6

In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
A) statistical significance.
B) correlation.
C) reliability.
D) standard deviation.
Answer:
In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
D) standard deviation.
Step-by-step explanation:
The more spread out or variable a data distribution is, the greater its standard deviation. A standard deviation is the square root of the variance. A mean is an average of all set of available data. It is obtained by dividing the value of data by the number of the data set. The standard deviation is the statistics that basically measure the distance from the mean, and is calculated as the square root of variance determined by each data point relative to the mean.
Question 6 of 14 Type the correct answer in the box. Use numerals instead of words. Joe owns a fast-food restaurant and wants to know the average time it takes for customers to receive their orders. His restaurant serves about 500 customers a day. He timed 5 orders, and the order times he collected, given in minutes, are shown below. Can the approximate order fulfillment time for all of the restaurant's customers be calculated from the given data? If so, calculate it. Non-integer answers should be rounded to the nearest tenth. If no assumption can be made, type "0" in the box. The approximate order fulfillment time for all of the restaurant's customers is minutes.
Answer:
The approximate order fulfillment time for all of the restaurant's customers is 0 minutes.

Claire is going to invest $2,600 and leave it in an account for 18 years. Assuming the interest is compounded continuously, what interest rate, to the nearest hundredth of a percent, would be required in order for Claire to end up with $4,300?
Answer:
Rate of interest r = 2.83 % (Approx.)
Step-by-step explanation:
Given:
Amount invested p = $2,600
Amount get A = $4,300
Number of year n = 18
Find:
Rate of interest r
Computation:
A = p(1+r)ⁿ
4,300 = 2,600(1+r)¹⁸
(1+r)¹⁸ = 1.653846
Rate of interest r = 2.83 % (Approx.)
Answer: 2.80%

Wrtire 55, 555 expanded form. How does the value of each 5 compare to the value of the 5 to its rights
Answer: ↓↓
Step-by-step explanation:
55,555 = 50,000 + 5,000 + 500 + 50 + 5
50 = 10 × 5
500 = 100 × 5
50,00 = 1000 × 5
50,000 = 10,000 × 5

Determine whether each piece of given information alone is sufficient to prove quadrilateral ABCD is parallelogram. Justify your answer. Yes/No? Reason... opposite side congruent, opposite angles congruent, opposite sides parallel, consecutive angles are supplementary, diagonals bisect each other, one pair of parallel and congruent sides, not enough information? (look at the image)
Answer:
Yes it is parallelogram because diagonals bisect each other.
Find the ninth term of the sequence
sprt(5), sprt(10), 2 sprt(5)
Answer:
16sqrt5
Step-by-step explanation:
Notice that the next term is the previous term multiplied by sqrt2.
So we can take sqrt5 and multiply it by sqrt2, 8 times to get the ninth term.
sqrt2 ^8 = 16.
So 16sqrt5

Given the ratio 2 green to 4 pink to 3 yellow (2:4:3), in a bag of 27 jellybeans, how many yellow jellybeans are in the bag?
The number of yellow jellybeans will be 9.
It is given that total number of jellybeans in a bag are 27 which are in ratio 2 green to 4 pink to 3 yellow or 2:4:3
We have to calculate the number of yellow jellybeans in the bag.
What will be the ratio of girls , if there are 80 students in a college , out of which 60 are male ?
The ratio of girls will be [tex]\frac{80-60}{80}[/tex] = [tex]\frac{20}{80}[/tex] = [tex]\frac{1}{4}[/tex] or 1:4.
As per the question ,
The ratio of jellybeans in a bag is 2 green to 4 pink to 3 yellow or 2:4:3.
Total number of jellybeans in the bag is 27.
So ,
Let's assume the common factor as x.
No. of green jelly = 2x
No. of pink jelly = 4x
No. of yellow jelly = 3x
We can write this as ;
2x + 4x + 3x = 27
9x = 27
x = 27 ÷ 9
x = 3
So , the number of yellow jellybeans will be ;
= 3 × x
= 3 × 3
= 9
Thus , the number of yellow jellybeans will be 9.
