Answer: 219 children and 72 adults swam at the public pool that day.

Step-by-step explanation:

Let x = Number of children , y= Number of adults.

As per given,  x+y = 291      (i)

1.5x+2y = 472.50         (ii)

Multiply 2 on both sides of (i) , we get

2x+2y = 582  (iii)

Eliminate (ii) from (iii), we get

0.5x = 109.5

[tex]\Rightarrow x=\dfrac{109.50}{0.5}=219[/tex]

Put value of x= 219 in (i)

219+y= 291

⇒ y = 291-219 = 72

Hence, 219 children and 72 adults swam at the public pool that day.

Answer:

The distance covered by a train in 1 minute = 1.25 kilometers

The distance covered by a train in 100 minutes = 125 kilometers

Step-by-step explanation:

The distance covered = 7.5 kilometers

Time taken = 6 minutes

Calculating unit rate

unit rate = 7.5 kilometers / 6 minutes

              = 1.25 kilometers per minute

Thus,

The distance covered by a train in 1 minute = 1.25 kilometers

and

The distance covered by a train in 100 minutes = 1.25 × 100

                                                                                = 125 kilometers

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

     3x + 1 = 6x - 4

     6x - 3x = 1 + 4

     3x = 5

     x = [tex]\frac{5}{3}[/tex]

11). If ABCD is a parallelogram,

     AB = CD

     5x - 8 = 2x + 7

     5x - 2x = 7 + 8

     3x = 15

     x = 5

12). If ABCD is a parallelogram,

     AB = CD

     AB║CD and BD is a transversal intersecting these parallel lines.

Answer:

The 2020th term is 3

Step-by-step explanation:

Recursive Sequence

We are given a recursive and conditional sequence where each term depends on two previous terms and a rule.

Each term is the sum of the two previous terms. But if that sum exceeds 8, then 8 is subtracted.

The first terms are, therefore:

1, 1, 2, 3, 5, 8, 5, 5, 2, 7, 1, 8, 1, 1, 2, 3, 5, 8, 5, 5, 2, 7, 1, 8, ....

Note the sequence repeats itself at term 13, that is:

a13=a1, a14=a2, a15=a3 and so on.

To find any given term, it's just a matter of calculating the remainder of that number of the term divided by 12.

For example, the term number 100 is calculated by dividing 100/12=8 (only the integer part).

Since 8*12=96, the remainder is 100-96=4

Thus, a100=a4=3

The term 2020 is calculated now:

2020/12 = 168 (integer only)

168*12=2016

The remainder is 2020-2016=4, thus

a2020 = a4 = 3

The 2020th term is 3

Answer: 1/15

Step-by-step explanation:

The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.

If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.

The probability that Derek selected a striped sock both times will be:

= 2/6 × 1/5.

= 2/30

= 1/15

Step-by-step explanation:

Answer:  $ 17.72

Step-by-step explanation:

Cost of soda = $2.15 , Cost of chicken = $8.77 , Cost of slice of cake = $4.10.

Total bill amount = (Cost of soda ) + (Cost of chicken) +(Cost of slice of cake)

= $ (2.15 + 8.77 +4.10)

= $ 15.02

Tip amount = 18% of Total bill amount

= 0.18 (15.02)

= $ 2.7036 ≈  $2.70

Entire bill = Total bill amount  + Tip amount

= $ ( 15.02+2.70)

= $ 17.72

Hence, entire bill = $ 17.72

Answer:

A. 35°C.

Step-by-step explanation:

35 C (Celsius), converted to F (Fahrenheit), would be 95. Which would make it a hot day.

Step-by-step explanation:

5 × -8 + 7 × -3 = -82

Answer:

d = 10.5, a₁ = - 3.5

Step-by-step explanation:

The n th term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₂ = 7 and a₄ = 28 , then

a₁ + d = 7 → (1)

a₁ + 3d = 28 → (2)

Subtract (1) from (2) term by term to eliminate a₁

2d = 21 ( divide both sides by 2 )

d = 10.5 ← common difference

Substitute d = 10.5 into (1)

a₁ + 10.5 = 7 ( subtract 10.5 from both sides )

a₁ = - 3.5 ← first term

Answer:

32 chickens

Step-by-step explanation:

Let

The number of cows = x

The number of chickens = y

A farm raises cows and chickens. The farmer has a total of 46 animals.

x + y= 46..... Equation 1

x = 46 - y

Number of legs of chickens = 2

Number of legs of cows = 4

One day he counts the legs of all his animals and realizes he has a total of 156 legs.

Hence:

2x + 4y = 156.... Equation 2

We substitute 46 - y for x in Equation 2

2(46 - y) + 4y = 156

92 - 2y + 4y = 156

- 2y + 4y = 156 - 92

2y = 64

y = 64/2

y = 32

Solving for x

x = 46 - y

x = 46 - 32

x = 14

The number of cows = x = 14 cows

The number of chickens = y = 32 chickens

Therefore, the number of chickens that the farmer has is 32 chickens

Answer:

A. A stratified random sample is a combination of simple random samples selected from each of several strata.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

1. Random sampling.

2. Convenience sampling.

3. Systematic sampling.

4. Cluster sampling.

5. Stratified sampling.

Stratified random sampling can be defined as a method of sampling that involves dividing a population into smaller groups known as strata.

In stratified random sampling, the strata are formed based on member's shared characteristics (e.g female or male, occupation, education) or attribute (e.g black or white).

Hence, the statement about stratified random sampling which is true is that, a stratified random sample is a combination of simple random samples selected from each of several strata.
