Irina predicted that she would sell 75 books, but she actually sold 95 books. Which expression would find the percent error?

Answers

Answer 1
Percent error = |actual error - expected error/ expected error| * 100%
(|75-95|)/95 = 0.21
0.21 * 100% = 21% error

Janice had an unpaid balance of $2358.19 on her credit card statement at the beginning of January. She made a payment of $80.00 during the month, and made purchases of $99.50. If the interest rate on Janice's credit card was 4% per month on the unpaid balance, find her finance charge and the new balance on February1.

Answers

Answer:

$2,639.19

Step-by-step explanation:

Her balance at the end of the month is

$2358.19 - $80.00 + $99.50 = $2537.69

So the finance charge is 2537.69 * 0.04% = $101.50

and her new balance is $101.50 + $2537.69 = $2639.19

Apples cost $1.89 per pound. What equation shows the relationship between total cost (t), price (p), and pounds purchased (n)?

1.89 = nt

n⁄t = 1.89

1.89t = n

t = 1.89n

Answers

Answer:

[tex]t(n) = 1.89n[/tex]

Step-by-step explanation:

From the given information

'p' denotes 'price per pound'

i.e. p = 1.89

'n' denotes the 'number of pounds purchased' 't' denotes the 'total cost '

Therefore, the equation becomes

[tex]t(n) = pn[/tex]

as

[tex]p=1.89[/tex]

so

[tex]t(n) = 1.89n[/tex]

Verification:

If you want to purchase 1 pound apple

i.e.

[tex]n=1[/tex]

Total cost would be:

[tex]t(1) = 1.89 (1)[/tex]

t = $1.89 per pound

Suppose the amount of a popular sport drink in bottles leaving the filling machine has a normal distribution with mean 101.5 milliliters (mL) and standard deviation 1.6. If 36 bottles are randomly selected, find the probability that the mean content is less than 102.1 mL

Answers

Answer:

0.98778

Step-by-step explanation:

When we are given a random number rod samples, we solve using z score formula

z = (x-μ)/σ/√n, where

x is the raw score = 102.1 mL

μ is the population mean = 101.5 milliliters (mL)

σ is the population standard deviation = 1.6.

n = 36

z = 102.1 - 101.5/1.6/√36

z = 2.25

Probability value from Z-Table:

P(x<102.1) = 0.98778

Hence, If 36 bottles are randomly selected, find the probability that the mean content is less than 102.1 mL is 0.98778

When a circular plate of metal is heated in an oven its radius increases at a rate of 0.01 cm/min. at what rate is the plates areas increasing when the radius is 54 cm?

Answers

Answer:

3.3912cm³/min

Step-by-step explanation:

Area of the circular plate = πr² where r is the radius of the plate.

dA/dt is the rate at which the plate is increasing

since dA/dr = 2πr and dr/dt = 0.01cm/min

dA/dt = dA/dr * dr/dt

dA/dt = 2πr dr/dt

dA/dt = 2π(54)(0.01)

dA/dt = 2π(0.54)

dA/dt = 3.3912cm³/min

Hence the rate at which the plates area is increasing when the radius is 54cm is 3.3912cm³/min

Luke measured caterpillars for a science project. He believes that caterpillar A is longer than caterpillar B because it has more digits after the decimal point. Do you agree or disagree Luke's thinking. Explain your reasoning.

Caterpillar A=4.125 cm
Caterpillar B=4.03
Caterpillar C=4.23

Answers

Answer: disagree

Step-by-step explanation:

Caterpillar A is longer, but not because of the decimal places. It is longer because of the place value.

Answer:

Disagreed

Step-by-step explanation:

In order to find the answer to this question you must remember that when dealing with finding the greater decimals you have to look at which have the greater place values in this case...

[tex]CA=4.125[/tex]

[tex]CB=4.03[/tex]

[tex]CC = 4.23[/tex]

Caterpillars 1 place value is already greater then caterpillar B's place value of 0, so it doesn't really matter how many more numbers to add after 1 and 0 because these two place values are already different 1 > 0

Meaning that "although Caterpillar A is greater then Caterpillar B, it is not because it has more digits simply because one is greater then zero." You can prove this by seeing that Caterpillar C is greater then Caterpillar A because two is greater then one.

[tex]4.125 > 4.03[/tex]

[tex]4.125 < 4.23[/tex]

Hope this helps.

86÷3 =

*The divisor is 3 and the dividend is 86

First step: How many 3's can fit into 8? (8÷3)

8÷3 = 2 r 2

Second step: add a 2 above the eight in the tens place of the answer.

86÷3 = 2_

Third step: multiply 3 x 2; 3 x 2 = 6;

In this step, we put a 6 underneath the 8.

Fourth step: Subtract.

In this step, we subtract 8-6 (=2)

Fifth step: bring down the next number. In this case, it is 6.

In this step, we now have the number 26.

Sixth step: How many 3's can fit into 26? (26÷3)

26÷3 = 8 r 2

Last step: Now put an 8 in the one's place and now we have a remaining 2. That is called the remainder. We put the remainder and represent it as "r". We put r2.

They are multicellular eukaryotes.
They don’t have a cell wall or chlorophyll like plants.
They have a heterotrophic mode of nutrition.
They can move from one place to another place.
