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 $

Answers

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

Answers

Answer:

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

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.

Answers

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.

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?

Answers

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.)

Find the ninth term of the sequence
sprt(5), sprt(10), 2 sprt(5)​

Answers

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

Formula for this is (sqrt(2)^(n-1))*sqrt(5) such that n is the term number
So sqrt(2)^8(sqrt(5))
The answer is (B) 16sqrt(5)

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?

Answers

2+4+3=9
27:9=3
2*3=6
4*3=12
3*3=9
So:green:6
Pink:12
Yellow:9

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.
