Answer:

0.09

Step-by-step explanation:

First off, we can write 0.9 as a fraction. Reading this, we would say "nine tenths"; this means the number in fraction form is 9/10.

The word "of" in mathematics means we multiply. Thus when we take 1/10 "of" 9/10, we multiply the two:

1/10(9/10)

To multiply fractions, multiply the numerators and multiply the denominators:

1/10(9/10) = (1*9)/(10*10) = 9/100

Converting this back to a decimal, we read 9/100 as "nine one-hundredths"; this means decimal form is 0.09.

Answer:

[tex]Probability = \frac{70}{143}[/tex]

Step-by-step explanation:

Given

[tex]Black = 5[/tex]

[tex]Red = 8[/tex]

[tex]Total = 13[/tex]

To solve the required probability, we need to determine the number of available selections:

There are two possible scenarios;

1: All 4 selections are red.

2. 1 selection is black, while 3 others are red

Scenario 1: All Red

[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]

[tex]^8C_4 = \frac{8!}{4!4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5*4!}{4!4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5}{4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5}{4*3*2*1}[/tex]

[tex]^8C_4 = \frac{1680}{24}[/tex]

[tex]^8C_4 = 70[/tex]

Scenario 2: 1 Black, 3 Red

Selecting Black:

[tex]^5C_1 = \frac{5!}{(5-1)!1!}[/tex]

[tex]^5C_1 = \frac{5!}{4!1!}[/tex]

[tex]^5C_1 = \frac{5*4!}{4!*1}[/tex]

[tex]^5C_1 = 5[/tex]

Selecting Red:

[tex]^8C_3 = \frac{8!}{(8-3)!3!}[/tex]

[tex]^8C_3 = \frac{8!}{5!3!}[/tex]

[tex]^8C_3 = \frac{8*7*6*5!}{5!3*2*1}[/tex]

[tex]^8C_3 = \frac{8*7*6}{6}[/tex]

[tex]^8C_3 = 8*7[/tex]

[tex]^8C_3 = 56[/tex]

Number of Selection = 5 * 56

[tex]Selection = 280[/tex]

Total Available Selection is calculated as thus:

[tex]Available\ Selection = 70 + 280[/tex]

[tex]Available\ Selection= 350[/tex]

Next, is to calculate the number of possible selections:

i.e 4 balls out of 13

This is calculated as:

[tex]^{13}C_4 = \frac{13!}{(13-4)!4!}[/tex]

[tex]^{13}C_4 = \frac{13!}{9!4!}[/tex]

[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10 * 9!}{9!4*3*2*1}[/tex]

[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10}{4*3*2*1}[/tex]

[tex]^{13}C_4 = \frac{17160}{24}[/tex]

[tex]^{13}C_4 = 715[/tex]

[tex]Probability = \frac{Available\ Selection}{Possible\ Selection}[/tex]

[tex]Probability = \frac{350}{715}[/tex]

[tex]Probability = \frac{70}{143}[/tex]

Answer:

a) The equation is:

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

b) The 98% confidence interval = (5.62784, 6.37216)

Step-by-step explanation:

a. Write down the equation you should use to construct the confidence interval for the average number of days absent per term for all the children. (10 points)

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

b. Determine a 98% confidence interval estimate for the average number of days absent per term for all the children. (10 points)

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

Mean = 6 days

Standard deviation = 1.6 days

Number of samples = 100

Z score of 98% confidence interval = 2.326

Confidence interval = 6 ± 2.326 × 1.6/√100

= 6 ± 2.326 × 1.6/10

= 6 ± 0.37216

= 6 - 0.37216

= 5.62784

6 + 0.37216

= 6.37216

Therefore, the 98% confidence interval = (5.62784, 6.37216)

Answer:

400,000+30,000

430,000

400,000-30,000

370,000

Step-by-step explanation:

Answer:

A:

2(x + 2) + 2(2x - 5) =

2x + 4 + 4x - 10 =

6x - 6

perimeter = 6x - 6

B:

(x+2)(2x - 5)            expand the brackets:

2x² - 5x + 4x - 10

area = 2x² - x - 10

C:

area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24

perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

Step-by-step explanation:

The circumference of a circle is given by :

C=2πr, r is the radius of the circle

Also, 2r = D, diameter of the circle

⇒ C = πD

If the diameter of a circle is multiplied by 10, it means,

C = π(10)

⇒ C = 10π

Hence, if the diameter of a circle is multiplied by 10, then its circumference becomes 10π.

Hi there

Your answer is

$42.08

To find the final price of the shoes, we would use the 15% discounted price, $46.75, as 100% and find 10% discount of that.

46.75 = 100%

/10

4.675 = 10%

Now, subtract 10% from the 15% discounted price

46.75 - 4.675 = 42.075$ Round up

$42.08

Answer:

find the final price by subtracting 10% from the sale price of $46.75 which is $4.68 making the final price $42.07

Given:

Emily claims that a tree height of 43 inches is an outlier for the distribution.

To find:

Evidence to support the claim if any.

Solution:

The starting and the end of the box in box plot are first and third quartile respectively.

From the given box plot it is clear that, [tex]Q_1=34[/tex] and [tex]Q_3=38[/tex].

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=38-34[/tex]

[tex]IQR=4[/tex]

According to 1.5x IQR rule for outliers, all the data values lies outside the interval [tex][Q_1-1.5\times IQR,Q_3+1.5\times IQR][/tex] are outliers.

Now,

[tex]Q_3+1.5\times IQR=38+1.5(4)[/tex]

[tex]Q_3+1.5\times IQR=38+6[/tex]

[tex]Q_3+1.5\times IQR=44[/tex]

We know that, 43<44.

Since, 43 is not greater than [tex]Q_3+1.5\times IQR[/tex], therefore, 43 is not an outlier and there is no evidence to support the claim.

Therefore, the correct option is D.

Answer:

I want to say it is the first one and the and the third one

Step-by-step explanation:

Answer:

The value  is   [tex]n_2  = 317[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n  =  73

   The proportion that in favor of raising the tuition is  [tex]\^{p} =  0.37[/tex]

   The standard deviation is  [tex]s_1  = 0.098[/tex]

    The required standard deviation  [tex]s_2  = 0.047[/tex]

Generally the requires standard deviation is mathematically represented as

      [tex]s_2  = s_1 *  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{s_2}{s_1}  =  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =0.2300[/tex]

=>     [tex]n_2 =  \frac{73}{0.2300}[/tex]

=>   [tex]n_2  = 317[/tex]

Answer:

Step-by-step explanation:

To find the acceleration given the mass and force we use the formula

[tex]a = \frac{f}{m} \\ [/tex]

where

a is the acceleration

m is the mass

F is the force

From the question

m = 78 kg

F = 69 N

We have

[tex]a = \frac{69}{78} = \frac{23}{26} \\ = 0.8846153...[/tex]

We have the final answer as
