From a sample of 120 batteries, 3 are faulty. Work out the percentage of faulty
batteries.

Answers

Answer 1

Answer:

2.5%

Step-by-step explanation:

% = (faulty batteries / total batteries) x 100

= (3/120) x 100

= 0.025 x 100

= 2.5

Lonnie plans to join the gym. He must pay a $35 membership fee. He will
then pay $5 each month. What is the slope?

Answers

Answer:

5

Step-by-step explanation:

The slope will be the constant amount that the cost increases by each month.

In this situation, 5 is the slope, because he has to pay $5 each month.

35 is not the slope, and is instead the y intercept. This is because this is the cost at 0 months, since it is the membership fee.

So, the correct answer is 5.

In a shop for every pant there are 3 shirts and for every 9 shirts there are 27 pairs of shoes. Express the ratio of pants to shirts to shoes in the shop.​

Answers

Answer:

Step-by-step explanation:

For every Pant = 3 shirts

If

Pant = x ; shirt = 3x

For :

Every 9 shirts = 27 pairs of shoes

Simplifying further :

1 shirt = 3 pairs of shoes

3 shirts = 3 * 3 = 9 pairs of shoes

Expressing as ratio:

Jack did 3/5 of the problems on his weekend homework before Sunday. On Sunday, he solved 1/3 of what was left and the last 4 problems. How many problems were assigned for the weekend?

Answers

Answer:

15 problems were assigned for the weekend.

Step-by-step explanation:

Let x denote the number of problems assigned for the weekend.

Before Sunday, he did 3/5 of the problems, so he is left with (1-3/5)x = 2/5 x of the problems.

On Sunday, he solved 1/3 of what was left of the problems, so he is left with (1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x problems.

4/15 x equals 4 because those were the last remaining problems, so we can solve for x:

[tex]\frac{4}{15}x=4\\x = 4 \cdot \frac{15}{4} = 15[/tex]

So 15 problems were assigned for the weekend.

Approximately__ tons of LNG will be produced in may, and approximately 104,489 tons will be produced in___
Help plz :,)

Answers

Answer:

Step-by-step explanation:

For all Plato users

Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.

Given that, the production of LNG by an energy company increases by 1.7% each month.

How to find the percentage of the number?

Convert the problem to an equation using the percentage formula: P% * X = Y.

Production in April month=91,307+1.7% of 91,307

=91,307+1.7% ×91,307

=92,859.219 tons

Production in May month=92,859.219×(1+1.7%)

=94437.825 tons

Production in June month=94437.825×(1+1.7%)=96,043 tons

Production in July month=96,043×(1+1.7%)=97,676 tons

Production in August month=97,676×(1+1.7%)=99,336.49 tons

Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons

Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons

94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

Volunteers for a human performance study were randomly divided into two groups. The first group had their flexibility measured in the morning after a short meditation session while the second group had their flexibility measured in the afternoon with no previous meditation session. The flexibility scores of the two groups were compared. This experiment was not double-blind because:

a. some of the volunteers stretched before they went to the study location.
b. volunteers were allowed to keep their eyes open while having their flexibility measured.
c. volunteers were randomized into the two groups.
d. the volunteers knew whether they had meditated before having their flexibility measured.

Answers

Answer:

C

Have a wonderful day!

The experiment was not double-blind because volunteers were randomized into the two groups. The correct option is c.

What is a double-blind experiment?

A type of clinical experiment where neither the research team nor the subjects are aware of the treatment or intervention they are receiving until the trial is complete. As a result, the study's findings are less likely to be skewed.

Because neither the participant nor the clinician is aware of who has received what treatment, double-blind studies are regarded as the most trustworthy sort of research. This is done in an effort to lessen bias and the placebo effect.

Both the researchers and the test subjects must be uninformed of who is receiving the treatment and who is receiving a placebo in a double-blind trial.

Therefore, the correct option is c. volunteers were randomized into the two groups.

The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $28.00. With the coupon book, the fare is reduced to $1.00. Determine the number of times in a month the bus can be used so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book

Answers

Answer:

56 = 56

Step-by-step explanation:

Given:

Bus fare = $2.00

coupon book = 28.00

bus fare w/ coupon book = $1.00

let x be the number of bus rides.

2.00x = 1.00x + 28.00

2.00x - 1.00x = 28.00

1x = 28.00

x = 28.00

24 bus rides for both to have the same cost.

2.00x = 1.00x + 28

2.00(28) = 1.00(28) + 28

56 = 28 + 28

Find all real square roots of -36

Answers

Answer:

The answer is ±6.

Step-by-step explanation:

The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...

6^2=6×6=36

(−6)2=(−6)×(−6)=36

All positive real numbers have a positive and negative real square root which are additive inverses of one another.

The principal square root is the positive one and is the one meant when we use the √... symbol. So:...

√36=6

If we want to refer to the negative square root, then just put a minus sign in front:...

−√36=−6

The two square roots of -36 are 6i and -6i, where i is the imaginary unit.

What is Number system?

A number system is defined as a system of writing to express numbers.

Since the square of any real number is always non-negative, there is no real number whose square is equal to a negative number.

Therefore, the expression √(-36) has no real square roots.

However, we can express the square root of -36 using imaginary numbers.

By definition, the imaginary unit "i" is equal to the square root of -1. Using this definition, we can rewrite √(-36) as:

√(-36) = √(36) × √(-1) = 6i

Therefore, the two square roots of -36 are 6i and -6i, where i is the imaginary unit.

Sam scored 17 out of 20 in her test, her % score is...... what A 17% B 85% C 80% D 0.85%​

Answers

Answer:

the answer is 85%

Step-by-step explanation:

To find the percentage you will divide:

17 divided by 20 = o.85

Answer:

B. 85%

Step-by-step explanation:

in order to find out her percentage, you want to do 17/20

the reason we do 17/20 and not 20/17 is because 20/17 gives you 1.1, which is both not an option and does not make logical sense

17/20 = 0.85

in order to make this a percentage, multiply 0.85 by 100

0.85 x 100 = 85

so your answer is 85%, or B

Which of the following functions represent exponential growth?
Which of the following functions represent exponential decay?

Answers

9514 1404 393

Answer:

  1. a, b, c - represent growth

  2. b, c, d - represent decay

Step-by-step explanation:

If increasing x results in a larger value, the function represents growth. If it results in a smaller value, the function represents decay.

__

To answer these questions, you can look at the base and the exponent. When we say "exponent" here, we mean the coefficient of the exponent variable. There are four possibilities:

  growth:

exponent positive, base > 1exponent negative, base < 1

  decay:

exponent positive, base < 1exponent negative, base > 1

__

Growth questions:

  1.77^x -- growth

  1.5^(x/2) -- growth

  0.5^(-x) -- growth (= 2^x)

  e^(-t) -- decay (e ≈ 2.718)

Decay questions:

  1.7^x -- growth

  1.7^(-2x) -- decay

  (1/3)^x -- decay (= 3^(-x))

  2^(-x) -- decay
