Answer:

Percent Decrease = 20% Decrease

Step-by-step explanation:

To find percentage decrease, we will use a simple formula shown below:

Percentage Decrease/Increase = $\frac{New-Old}{Old}*100$

Where

New is the latest number of members (which is 24)

Old is the initial number of members (which is 30)

<em>Note: the multiplication by a factor of "100" brings the answer to a percentage</em>.

Now, lets substitute the numbers and figure out the percentage decrease:

$\frac{New-Old}{Old}*100\\\frac{24-30}{30}*100\\\frac{-6}{30}*100\\-0.2*100\\-20$

So, it comes to -20, which is a decrease of 20%

I payed for a subsciption my bank has already been debted but it wont let me use it. why not?

ANEK [815]

Answer:

If your payment didn’t go through, change your preferred payment method/add another payment method.

For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.

Suppose RS is conjurated to MN. For each of the set of lengths, solve for X, and find the length of each segment.

NeX [460]

If RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

Given RS is congruent to MN.

We are required to find the value of x if RS is congruent to MN.

Congruent lines are those lines whose lengths are equal to each other.

1) RS=x+10, MN=2x+4.

Because the congruent lines have equal lengths so , RS=MN.

x+10=2x+4

x-2x=4-10

-x=-6

x=6

2) RS=3x-2, MN=x+6

Because the length of lines are equal,so RS=MN.

3x-2=x+6

3x-x=6+2

2x=8

x=4

3) RS=5x-10, MN=2x+20

The lengths are equal so RS=MN.

5x-10=2x+20

5x-2x=20+10

3x=30

x=10

Hence if RS is congruent to MN then the value of x in all the parts are 6,4, and 10.

Lynne bought a bag of grapefruit, 1 5/8 pounds of apples, and 2 3/16 pounds of bananas.The total weight of her purchases was 7 1

Rufina [12.5K]

The bag of grapefruit weighs 3 and 11/16
first: find a common denominator of 1/2, 5/8, and 3/16; 16 is the least common multiple.
16 divided by 2 is 8, so we multiply 1 by 8 and have 8/16
16 divided by 8 is 2, so we multiply 5 by 2 and have 10/16.
now, the three quantities given are 1 and 10/16, 2 and 3/16, and 7 and 8/16.
then, we subtract 1 and 10/16 from 7 and 8/16
7 8/16
- 1 10/16
this is 5 and 7/8, or 5 and 14/16

then, we subtract 2 and 3/16 from 5 and 14/16 to get 3 and 11/16

there you have it :)

Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical Saturday, the oil-chang

Artemon [7]

Answer:

The answer is given below

Step-by-step explanation:

The mean (μ) = 21.2 minutes and the standard deviation σ = 3.5 minutes.

the oil-change facility will perform 45 oil changes between 10 A.M. and 12 P.M, therefore the sample size n = 45

there be a 10% chance of being at or below. From the normal distribution table, The z score corresponding to a probability of 10% (= 0.1) is -1.28.

z = -1.28

To calculate the mean oil-change time, we use the formula:

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }\\\\ Substituting \ values:\\-1.28=\frac{x-21.2}{\frac{3.5}{\sqrt{45} } }\\\\x-21.2=-0.6678\\\\x=-0/6678+21.2\\\\x=20.5$
