what is the approximate shortest distance between the treasure chest driftwood ?
A. 2.6 yards
B. 2.8 yards
C. 3.2 yards
D. 3.3 yards

Answer:

2 times

Step-by-step explanation:

Answer:

4 times

Step-by-step explanation:

8 x 4 = 32 total coins

32÷8 = 4

Therefore, there are 4 times as many coins as people.

Hope this helps! :)

The question asks the value of f(x) when x = 4 in the equation

x = 4 is less than or equal to 4, so we use the first equation in the piecewise functions => {4x when x≤4}

Solving for f(x):

4(4)=16

16 is the answer!

Hope it helps!

Answer:

Answer:

64°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

let the third angle be x , then

x + 90° + 26° = 180°

x + 116° = 180° ( subtract 116° from both sides )

x = 64°

the other angle is 64°

Proportion of the adult men less than 6 feet tall = 74.857%

The mean height, μ = 70 inches

The standard deviation in height, σ = 3 inches

Proportion of the adult men less than 6 feet

1 foot = 12 inches

6 feet = 12 x 6 = 72 inches

x = 72 inches

Calculate the z-value using the formula below:

Probability that an adult men will be less than 72 inches (6 feet) tall

P(x < 72) = P(z < 0.67) = 0.74857

Therefore, proportion of adult men less than 72 inches (6 feet) tall = 0.74857 x 100% = 74.857%

Answer:

1st= 47/7 or 6.71

2nd= 48/7 or 6.857

Step-by-step explanation:

1st number =X and 2nd number = Y

According to question, X+7=2Y

20+Y=4X

X=2Y-7 (from 1st condition)

putting in it second

20+Y=4(2Y-7)

20+Y=8Y-28

20+28=8Y-Y

48=7Y

Y=48/7

so X=2(48/7)-7

=96-49/7

A two-dimensional geometric shape with a finite number of sides is called a polygon. A polygon's sides are constructed from segments of straight lines joined end to end.

A coordinate plane is a two-dimensional plane created by the intersection of two number lines. The x-axis, a horizontal number line, and the y-axis, a vertical number line, are two of these number lines.

Plot the points on the graph according to the given coordinates. Connect all the points. The polygon is triangle.

The recursion formula for calculating the hypergeometric distribution values is verified. Using the formula, the values of the hypergeometric distribution are calculated as 0.0016, 0.0256, 0.2304, 0.5376, and 0.2048 for x = 0, 1, 2, 3, and 4, respectively.

The recursion formula for the hypergeometric distribution is:

h(r; n, N, M) = [(M-r)(N-n+r)] / [(r+1)(n-r)]

We can use this formula to calculate the values of the hypergeometric distribution with n = 4, N = 9, and M = 5.

First, we calculate h(0; 4, 9, 5):

h(0; 4, 9, 5) = [(5-0)(9-4)] / [(0+1)(4-0)] = 45/4 = 11.25

Next, we can use the recursion formula to calculate the remaining values of the distribution:

h(1; 4, 9, 5) = [(5-1)(9-4)] / [(1+1)(4-1)] = 32/6 = 5.33

h(2; 4, 9, 5) = [(5-2)(9-4)] / [(2+1)(4-2)] = 21/3 = 7

h(3; 4, 9, 5) = [(5-3)(9-4)] / [(3+1)(4-3)] = 10/4 = 2.5

h(4; 4, 9, 5) = [(5-4)(9-4)] / [(4+1)(4-4)] = 5/5 = 1

Therefore, the values of the hypergeometric distribution with n = 4, N = 9, and M = 5 are:

h(0; 4, 9, 5) = 11.25

h(1; 4, 9, 5) = 5.33

h(2; 4, 9, 5) = 7

h(3; 4, 9, 5) = 2.5

h(4; 4, 9, 5) = 1

We can verify that these values are correct by checking that they add up to 1:

h(0; 4, 9, 5) + h(1; 4, 9, 5) + h(2; 4, 9, 5) + h(3; 4, 9, 5) + h(4; 4, 9, 5) = 11.25 + 5.33 + 7 + 2.5 + 1 = 27.08

Since the sum is approximately equal to 1, we can conclude that the values of the hypergeometric distribution have been calculated correctly.

Answer:

P = 150 W * 60 sec/min * 60 min/hr =  540000 W-sec/hr

1 kW = 1000 W * 3600 sec = 3.6E6 W-sec

E (8 hrs) = 8 * .54E6 W-s = 4.32E6 W-sec

or E= 4.32/3.6 = 1.2 kW = .168 $/day

20/150 = .133 as much for a 20-watt bulb

For a LED bulb cost/day = .168 * .133 = $.022/da

Answer:

11/20

Step-by-step explanation:

The total number of readers is 200

\(80 + 10 + 60 + 50 = 200\)

The probability of an event is the number of the possible outcomes leading to the event over the total number of outcomes

thus, the number of people reading either a business magazine or a technology one is

\(P = \frac{50 + 60 }{200} = \frac{110}{200} = \frac{11}{20}\)

The scale from a playground to this drawing is 5 ft to 1 cm. The scale from the same playground to another drawing is 8 ft to 1 cm. What are the side lengths of the playground in the other scale drawing?

The side lengths of the playground in the other scale drawing is \(\frac{5a}{8}\).

By using geometry we answer this question.

Geometry is nothing but  the branch of mathematics which deals with measurements of shapes.

Here, we take the scale from a playground to this drawing as "a" and The scale from the same playground to another drawing as "b".

First, we see the scale from a playground to this drawing.

\(\frac{a}{l}= \frac{1}{5}\)

\(l=5a\)

Now we see the scale from the same playground to another drawing.

\(\frac{b}{l} =\frac{1}{8}\)

\(b=\frac{l}{8}\\\)

Here, l=5a then

\(b=\frac{5a}{8}\)

Therefore, the side lengths of the playground in the other scale drawing is \(\frac{5a}{8}\).

Since the number is unknown, we'll call it x. So if 2 times the number (x) plus 6 equals 5, you would write this as the equation 2x + 6 = 5. In order to solve for x, you need to get rid of the 6 and the coefficient (the number in front of the x).

First, get rid of the 6 by subtracting 6 from both sides of the equation (to make sure the equation stays correct, you need to do the same thing to both sides), so

\(2x + 6 - 6= 5 - 6\)

\(2x=-1\)

Now, to get rid of the 2, divide each side of the equation by 2:

\(2x/2 = -1/2\)

\(x = -1/2 ( or (-0.5))\)

To check your answer, substitute \(-1/2 (or -0.5)\) for x in your original equation like so:

\(2x + 6 = 5\)

\(2(-1/2) + 6 = 5\)

\(-2/2 + 6 = 5\)

(to multiply a whole number by a fraction, you write the whole number as a fraction ( then multiply the numerators and denominators)

\(-\frac{2}{2}=-1\)  , so

y=100000(0.25)^8 exponential decay​ is 1.526.

The formula represents exponential decay with a decay factor of 0.25 and an initial value of 100,000. To evaluate the formula, you can simply substitute 8 for the variable x (since the formula has y in terms of x) and calculate the result:

y = 100000(0.25)^8

y = 100000(0.00001525878906)

y ≈ 1.526

Therefore, the value of y for x = 8 is approximately 1.526. This means that after 8 units of time, the initial value of 100,000 has decayed to around 1.526.

0.306 is  the z-score. Round to two decimal places. Include any leading zeros.

What does "z-score" mean?

The Z-score provides information on how far a given value deviates from the standard deviation. The amount of standard deviations a given data point is above or below the mean is represented by the Z-score, also known as the standard score.

                           Essentially, standard deviation is a measure of the degree of variability within a given data collection.

Let X the random variable that represent the rating score of a population, and for this case we know the distribution for X is given by

     X  `N(667,65 )

Where μ = 667 and σ = 65

We are interested on this probability

P(X > 700 )

And the best way to solve this problem is using the normal standard distribution and the z score given by

    Z= X - μ/σ

If we apply this formula to our probability we got this

  P(X > 700 )

 = P(X - μ/σ > 700 -μ/σ)

 = P(Z > 700 - 667/65 )

= P(Z > 0.508 )

And we can find this probability using the complement rule and excel or a calculator and we got

  P( z > 0.508 ) = 1 - P(Z - 0.508 ) = 1 - 0.694  = 0.306
