Answer:

160

Step-by-step explanation:

20 x 2 = 40

40 x 2 = 80

80 x 2 = 160

It stops at 3 years.

Answer:

120

Step-by-step explanation:

20+40+60 = 120

If we double it, we have to keep adding 20 each year and stop at 3 so the answer is 120

Distribute the 2

Answer:

0.1764

Step-by-step explanation:

This problem meets requirement that enables us to use the binomial probability relation :

Probability of success, p = 17% = 0.17

number of trials = 9

(1 - p) = 1 - 0.17 = 0.83

The binomial probability relation :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x = 3) = 9C3 * 0.17^3 * 0.83^6

P(x = 3) = 84 * 0.001606258054361897

P(x = 3) = 0.134925676566399348

P(x = 3) = 0.13492

P(x = 4) = 9C4 * 0.17^4 * 0.83^5

P(x = 4) = 126 * 0.000328992613544003

P(x = 4) = 0.041453069306544378

P(x = 4) = 0.04145

P(x = 3 or x = 4) = P(x = 3) + p(x = 4)

= 0.13492 + 0.04145

= 0.17637

= 0.1764

Answer:

a) probability that any individual student has a flu shot is  0.30

b) The probability that more than 30 students have had flu shots is 0.1038

c) the probability that 20 or fewer students have had shots is 0.1314

Step-by-step explanation:

Given the data in the question;

Number of students n = 84

student health clinic reports that only 30% of students got a flu shot this year;

p = 30% = 0.30

now,

pn = 0.30 × 84 = 25.2 ( > 10 )

qn = (1-p)n = (1-0.30)84 = 0.70 × 84 = 58.8  ( > 10 )

Criterion for approximation of the binomial distribution is satisfied since both pn and qn are greater than 10.

hence, Normal distribution will have;

mean μ = np = 0.30 × 84 = 25.2

standard deviation σ = √( npq )

= √( 84 × 0.30 × 0.70 )

= √17.64

standard deviation σ = 4.2

a) the probability that any individual student has a flu shot

student health clinic reports that only 30% of students got a flu shot this year

p = 30% = 0.30

Therefore, probability that any individual student has a flu shot is  0.30

b) The probability that more than 30 students have had flu shots

P(X > 30)

we use real time limits to determine probability from binomial distribution,

hence upper limit will be 30.5

Z = (X - np) / √( npq )

Z = ( 30.5 - 25.2 ) / 4.2

Z = 5.3 / 4.2

Z = 1.26

from normal distribution table

[tex]Z_{1.26[/tex] = 0.1038

Therefore, The probability that more than 30 students have had flu shots is 0.1038

c) the probability that 20 or fewer students have had shots;

P( X ≤ 20 )

upper limit will be 20.5

Z = (X - np) / √( npq )

Z = ( 20.5 - 25.2 ) / 4.2

Z = -4.7 / 4.2

Z = -1.12

from normal distribution table

[tex]Z_{-1.12[/tex] = 0.1314

Therefore, the probability that 20 or fewer students have had shots is 0.1314

Answer:

9.9 lb of cashews and 23.1 lb of Brazil nuts

Step-by-step explanation:

cashews×$6.80 + Brazil nuts×5.50 = 33 lb × $5.89

C +B = 33lb

C = 33 - B

(33-B)(6.80) + B(5.50) = $194.37

224.4 - 6.80B + 5.50B = 194.37

-1.3B = -30.03

B = 23.1

C = 33 - 23.1

C = 9.9

Answer:

24π cm

Step-by-step explanation:

s = (∅/360) * 2πr

s = (216/360) * 2π(20)

s =  (216/360) * 2 * 20 * π

s = 24π cm

Answer:

(-6,2)

Step-by-step explanation:

when it asks for the scale factor all you do is take your coordinates and multiply it by whatever the question gives you. Like in this question you would multiply -3 and 1 by 2 and whatever the number comes out to be then thats your answers.

Sorry if the explanation isnt very good!

Answer:   1700

Step-by-step explanation:

hope this helps

0.05 can be obtained in 85 1700 times

The number of times 0.05 can be obtained in 85 is 1700.

One of the four fundamental arithmetic operations, along with addition, subtraction, and division, is multiplication. Multiplication is essentially the process of repeatedly adding sets of identically sized objects. The symbols for multiplication are cross (×), asterisk (*), and dot (.).

Let the number of times be x.

So, x times 0.05 is 85.

Mathematically, we can write the above statement as

0.05 * x = 85

i.e. x = 85/0.05 = 1700

Therefore, the number of times 0.05 can be obtained in 85 is 1700.

Answer:

Because there are 9 sour straws in total and 3 blue sour straws, the probability of pulling out a blue sour straw would be 3/9 or 1/3. Because we aren't replacing it, that means that there's one less straw in the box so there should only be 8 straws left. Because there's 4 pink sour straws, the probability of pulling out a pink sour straw is 4/8 or 1/2.

Answer:

Step-by-step explanation:

Answer:

For a data set of N elements:

{x₁, x₂, ..., xₙ}

The median is the middle value (or the average of the two middle values)

The average or mean is:

[tex]m = \frac{x_1 + ... + x_n}{N}[/tex]

The mode is the value that is more repeated.

The range is the difference between the largest value and the smallest value.

Now, let's try to construct two sets A and B that meet the required conditions:

Let's suppose two sets of 5 values each:

A = {2, 2, 3, 4, 5}

The median of A is 3.

The range of A is = 5 - 2 = 3

The average of A is: (2 + 2 +3 +4 +5)/5 = 16/5

And the value "2" appears two times, so the mode is 2.

Now, let's try to find a data set B such that:

The mode is smaller than 2  (so for example, we can have a "1" that repeats two times)

The median is smaller than 3 (let's have a median equal to 2)

The average is larger than 16/5

The range is larger than 3

This is ratter simple:

B = {1, 1, 2, 6, 9}

The median of B is 2.

The mode of B is 1

The range of B is: 9 - 1 = 8

The average of B is: (1 + 1 + 2 + 6 + 9)/5 = 19/5

So, we just found an example for two data sets A and B such that A has a greater median and mode, while B has a greater average and range.

So the answer is yes, it is possible.

Answer:

Distance in ft = 597.57 feet

Step-by-step explanation:

As per the

First equation of motion

84 mph = 37.5514 m/s

45 mph = 20.1168 m/s

v-u = a* t

Substituting the given values, we get -

37.5514 m/s - 20.1168 m/s = a * 6.3

a = 2.76 m/s^2

Now as per Newton's third law of motion

v^2-u^2 = 2 *a*S

Substituting the given values, we get -

37.5514^2 - 20.1168^2 = 2 * 2.76 m/s^2 * S

S = 182.142 Meters

Distance in ft = 597.57 feet

Answer:

The right solution is "0.196".

Step-by-step explanation:

The given values are:

Standard deviation,

[tex]\sigma=1 \ minute[/tex]

Sample size,

[tex]n=100[/tex]

Confidence level,

[tex]c=95[/tex]%

  [tex]=0.95[/tex]

Now,

For [tex]\alpha=1-c[/tex]

         [tex]= 1-0.95[/tex]

         [tex]=0.05[/tex]

then,

[tex]Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }[/tex]

     [tex]=Z_{0.025}[/tex]

     [tex]=1.96[/tex]

The margin or error will be:

⇒ [tex]E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })[/tex]

On substituting the values, we get

       = [tex]1.96(\frac{1}{\sqrt{100} })[/tex]

       = [tex]1.96\times \frac{1}{10}[/tex]
