Answer:

18%

Step-by-step explanation:

Divide 64/303.

Divide 9/303.

Subtract the answers and you'll get 18%.

The percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18.25%

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

Given here, according to the survey, the population with Brown eyes & black hair and Blue eyes and black hair  is 64 and 9 respectively

Also, the marginal total is equal to 303

therefore, the percentages of the two groups are

Brown eyes & black hair =64/303 × 100

                                         = 21.12%

similarly we can calculate  Blue eyes and black hair = 9/303 × 100

                                                                                      = 2.97%

Hence the difference is  21.22% - 2.97% =  18.25% (approx)

Answer:

144 inches squared

Answer:

0.99186 probability that the person will not die in the next year, and the correct option is A.

Step-by-step explanation:

Dying and not dying in that year are complementary events, that is, one of them will happen. This means that the sum of their probabilities is 100% = 1.

The probability of dying is:

[tex]p = \frac{814}{100000} = 0.00814[/tex]

So the probability of not dying is given by:

[tex]P = 1-0.00814 = 0.99186[/tex]

0.99186 probability that the person will not die in the next year, and the correct option is A.

Answer:

The car will travel  525 miles on 15 gallons of gas.

Step-by-step explanation:

Given that car can travel 35 miles using 1 Gallon of gas.

so

Unit rate = 35 miles per gallon

Thus,

The number of miles a car can travel in 15 gallons = 15 × 35

                                                                                    = 525 miles

Thus, the car will travel  525 miles on 15 gallons of gas.

Answer:

h = 231 feet

Step-by-step explanation:

Given that,

A person standing 248 feet from the base of a church, x = 248 feet

The angle of elevation to the church's steeple to be 43°.

We need to find the tall of the church. Let the length of the church is h. Using trigonometry to find it.

[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{h}{x}\\\\h=x\tan\theta\\\\h=248\times \tan(43)\\\\=231.26\ \text{feet}[/tex]

or

h = 231 feet

So, the height of the church is 231 feet.

Answer:

A) standard deviation of the sampling distribution of x is 0.5307

B) the sample size needs to be 16, if you want the standard deviation of   the sampling distribution of x to be 0.325

Step-by-step explanation:

Given that;

Population mean μ = 53.7

standard deviation σ = 1.3

sample size n = 6

Sampling distribution of x" follows Normal distribution

x" η N ( μ_x" =μ, σ_x"= σ/√n)

A)

standard deviation of the sampling distribution of x

⇒X" = σ_x" = σ/√n

we substitute

= 1.3/√6

= 1.3 / 2.4494

= 0.5307

Therefore standard deviation of the sampling distribution of x is 0.5307

B)

if σ_x" = 0.325

⇒  σ/√n = 0.325

we substitute in the value of σ

⇒ 1.3/√n = 0.325

√n = 1.3 / 0.325

√n = 4

n = 4²

n = 16

Therefore the sample size needs to be 16, if you want the standard deviation of   the sampling distribution of x to be 0.325

Answer:

x=9

Step-by-step explanation:

So first subtract 8 on both Sides

3x+8-8=35-8

3x=27

Now divide 3 on both sides to isolate the variable x

x=9

So x=9

Answer:

so to do this you need to subtract 8 from 35 to get 27 now do 27 divide by 3 to get 9

3x+8=35

3x=35 - 8 = 27

3x = 27

3x divided by 27 = 9

Step-by-step explanation:

a=21

The equation of the parabola that goes through the three points is:

y = 3x² + 14x + 8

The points are given as:

(-5,13), (0,8), (2,48)

To find the equation of the parabola that goes through the given three points (-5,13), (0,8), and (2,48) using quadratic regression, we need to fit a quadratic equation of the form y = ax² + bx + c to these data points.

Using the three points, we can set up a system of equations:

13 = a(-5)² + b(-5) + c

8 = a(0)² + b(0) + c

48 = a(2)² + b(2) + c

Simplifying these equations, we have:

25a - 5b + c = 13

c = 8

4a + 2b + c = 48

Solving this system of equations, we find that a = 3 and b = 14, and c = 8.

Therefore, the equation of the parabola that goes through the three points is:

y = 3x² + 14x + 8

Answer:

Step-by-step explanation:

It is given that,

The time for one swing is proportional to the square root of the length of the string.

[tex]T\propto \sqrt{L}[/tex]

or

[tex]\dfrac{T_1}{T_2}=\sqrt{\dfrac{L_1}{L_2}}[/tex] ....(1)

We have,

L₁ = 64 cm, T₁ = 1.6 s, L₂ = 144 cm, T₂ = ?

Substitute all the values in formula (1).

[tex]T_2=\dfrac{T_1}{\sqrt{\dfrac{L_1}{L_2}}}\\\\T_2=\dfrac{1.6}{\sqrt{\dfrac{64}{144}}}\\\\T_2=2.4\ s[/tex]

So, the new time period of the simple pendulum is 2.4 seconds.

Which means that we can assume each student got 4 questions correct

Because all entries are the same the standard deviation is 0

Answer:

a)£21.80

b) 3 trips

Step-by-step explanation:

The cost of an adult is $10.

A child’s ticket is $6.

FAMILY DISCOUNT CARD

- 45% off all adults tickets

- Children save 2/5 off of full price tickets

a) How much will it cost to buy 2 adult tickets and children’s tickets?

(a)

Adults: 2 × £10 = £20

(45 ÷ 100) x £20 = £9

£20 - £9 = £11

Children: 3 × £6 = £18

2 /5 of £18 = £7.20

£18 - £7.20 = £10.80

Total: £11 + £10.80 = £21.80

b) The cost of a family discount card is $40 per year. How many times in the same year would 2 adults and 3 children need to go before you start to savemoney on the cost of the card?

(b) Cost without discount = £20 + £18 = £38b)

No card

1 trip

1 × £38 = £38

2 × £38 = £76

3 × £ 38 = £114

With card

£40 + (1 × £21.80) = £61.80

2 trips 2 × £38 = £76 £40 + (2 × £21.80) = £83.60

3 trips 3 x £38 = £114 £40 + (3 × £21.80) = £105.40

3 trips before the discount card starts being cheaper than regular price

Answer: I think it's (0.857142857143 as a fraction equals 857142857143/1000000000000)

Step-by-step explanation:

0.857142857143 as a fraction is 7.714285714287/9, which cannot be simplified further.

Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point.

To convert 0.857142857143 to a fraction:

Let x = 0.857142857143

Then 10x = 8.57142857143

Subtracting x from 10x gives:

10x - x = 8.57142857143 - 0.857142857143

Simplifying:

9x = 7.714285714287

Dividing by 9:

x = 0.857142857143 = 7.714285714287/9

Therefore, 0.857142857143 as a fraction is 7.714285714287/9, which cannot be simplified further.
