Answer 1

Answer:

(a) 2.6 m^2

(b) 3.9 m^3

Step-by-step explanation:

(a)

ABCD is a trapezoid.

A = (B + b)h/2

A = (1.7 m + 2.3 m)(1.3 m)/2 = 2.6 m^2

(b)

The skip is shaped like a prism with trapezoidal bases.

V = area of base * height

V = 2.6 m^2 * 1.5 m = 3.9 m^3

The amount of mustard dispensed from a standard dispenser is normally distributed with a mean of 0.9oz and a variance of 0.01oz. If a family of six buys ten hotdogs total and dispenses mustard onto each one using the standard dispenser, what is the probability that more than 3 of them will have more than one ounce of mustard?

Answers

Answer:

the probability that more than 3 of them will have more than one ounce of mustard is 0.05975

Step-by-step explanation:

Given te data in the question;

let x rep the quantity of mustard on a hotdog ( in oz)

so

X → N ( u = 0.9, α² = 0.01 )

now P( more than one ounces of mustard on a hotdog) will be

P( X>1 ) = P( Z > ((1-0.9)/(√0.01)) ) = P( Z > 1 ) = 1 - P( Z < 1 )

= 1 - 0.84134 = 0.15866

Also let Y rep the number of hotdogs that have more than one ounces of mustard, so

Y → Bin( n = 10, p = 0.15866 )

P( y = y ) = (¹⁰ _y) ( 0.15855)⁰ ( 1 - 0.15866 )^10-y, y = 0,1,2,3......, 10

so required probability = P(Y > 3) = 1 - P(Y ≤ 3)

= 1 - P(Y=0) - P(Y=1) - P(Y=2) - P(Y=3)

=1 -  (¹⁰ ₀) ( 0.15855)⁰ (1 - 0.15855)¹⁰⁻⁰ - (¹⁰ ₁) ( 0.15855)¹ (1 - 0.15855)¹⁰⁻¹ - (¹⁰ ₂) ( 0.15855)² (1 - 0.15855)¹⁰⁻² - (¹⁰ ₃) ( 0.15855)³ (1 - 0.15855)¹⁰⁻³

= 0.05975

Therefore the probability that more than 3 of them will have more than one ounce of mustard is 0.05975

Find the sample size required to estimate the percentage of college students who take a statistics course. Assume that we want 95% confidence that the proportion from the sample is within four percentage points of the true population percentage. Round the answer to the next larger whole number.

Answers

Answer:

The sample size is    [tex]n = 600 [/tex]

Step-by-step explanation:

From the question we are told that

   The margin of error is  E = 4% = 0.04

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Since the sample proportion (point estimate of the population proportion was not give we will assume it to be  )

       [tex]\^ p = 0.5[/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{1.96}{0.04} ]^2 * 0.5 (1 - 0.5 ) [/tex]

=>  [tex]n = 600 [/tex]

Three times the sum of three consecutive integers is 72. What are the integers? a. 4, 5, 6 c. 9, 10, 11 b. 7, 8, 9 d. 6, 7, 8

Answers

Answer:

B

Step-by-step explanation:

7+ 8+ 9= 24

24 x 3= 72

Answer:

The three integers whose three times the sum of three consecutive integers is 72 will be: 7, 8, 9

Step-by-step explanation:

Let x, y, and z be the three consecutive integers

The sum of x, y, and z will be: x+y+z

The three times the sum of three consecutive integers is 72.

so the equation becomes:

3(x+y+z)=72

Now, putting x = 7, y=8 and z=9 in the L.H.S equation to check

3(x+y+z)

⇒ 3(7+8+9)

⇒ 3(24)

⇒ 72

Therefore, it is clear that the three integers whose three times the sum of three consecutive integers is 72 will be: 7, 8, 9

A.0
B 1

C. 2
D infinitely many

Answers

Answer:

The answer Is D Infinitely many.

Although these triangles will have the same shape and will have proportional sides due to the angle measures, at least one side length must be given to determine the other lengths, and so the size is not specified. Therefore the combination of lengths are infinite. This is because all numbers go on forever, just as you can keep counting without stopping.

Four gallons of water weigh 33.4 lb
How much do 7.5 gallons of water weigh?
b)
Four gallons of water weigh 33.4 lb
Find the constant of variation.

Answers

Answer:

a) 62.625 lb

b) 8.35

Step-by-step explanation:

a)

Use a proportion.

4 gal is to 33.4 lb as 7.5 gal is to x lb.

4/33.4 = 7.5/x

4x = 33.4 * 7.5

4x = 250.5

x = 62.625

Answer: 62.625 lb

b)

33.4/4 = 8.35

1) Cost of 7.5 gallons of water = 62.63 lb

2) The constant of variation = 8.35 lb

We have to given that,

1) Cost of 4 gallons = 33.4 lb

2) And, Cost of 4 gallon of water = 33.4 lb

Hence, We can simplify it as,

1) Since, Cost of 4 gallons = 33.4 lb

Hence, Cost of 7.5 gallons = 7.5 × 33.4 / 4 lb

                                         = 62.63 lb

2) Since, Cost of 4 gallon of water = 33.4 lb

Hence,  the constant of variation = 33.4 / 4

                                                   = 8.35

Answers

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

[tex]\mu[/tex] = 79

Standard deviation,

[tex]\sigma[/tex] = 3.5

Now,

⇒ [tex]\sigma\bar x = \frac{\sigma}{\sqrt n}[/tex]

         [tex]= \frac{3.5}{\sqrt 16}[/tex]

         [tex]=0.875[/tex]

⇒ [tex]P(\bar x > 81) = 1 - P(\bar x < 81)[/tex]

So,

= [tex]1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x} < \frac{(81 - 79) }{0.875} ][/tex]

= [tex]1 - P(z < 2.2857)[/tex]

The value of a school bus reduces from $512000 to $343000in 3 years. Find the
uniform rate of depreciation per annum (R).​

Answers

Answer:

The uniform rate of depreciation is $56,333 per year, or 11% per year.

Step-by-step explanation:

Rate of Depreciation

If some object has a certain value P and after some time t its value decreases to Q, the rate of depreciation is a measure of how much its value changed per unit time.

It can be calculated as:

[tex]\displaystyle R=\frac{P-Q}{t}[/tex]

It can also be expressed as a percentage, dividing the previous value by P.

The school bus reduces its value from $512,000 to $343,000 in 3 years, thus:

[tex]\displaystyle R=\frac{512,000-343,000}{3}[/tex]

[tex]\displaystyle R=\frac{169,000}{3}[/tex]

R = 56,333 $/year

Expressed as a percentage:

R = 56,333 / 512,000 = 0.11

R = 11%/year

The uniform rate of depreciation is $56,333 per year, or 11% per year.

Suppose that the log-ons to a computer network follow a Poisson process with an average of three counts per minute.

Required:
a. What is the mean time between counts?
b. What is the standard deviation between counts (in minutes)?
c. If it is an average of 3 counts per minute, find the value of x such that P(X < x) = 0.95

Answers

Answer:

a. E(X) = 0.333 minutes

b. [tex]\mathbf{\sigma_x =0.333 \ minutes}[/tex]

c.  0.9986

Step-by-step explanation:

a.

To find the mean time between counts

Let X be the random variable that illustrates the time between the successive log-ons, then X is exponential with the rate [tex]\lambda = 3[/tex] log-ons per minute.

i.e.

[tex]E(X) = \dfrac{1}{\lambda}[/tex]

[tex]E(X) = \dfrac{1}{3}[/tex]

E(X) = 0.333 minutes

b. Since X is attributed to an exponential distribution, The standard deviation between counts is:

[tex]\sigma_x = \dfrac{1}{3}[/tex]

[tex]\mathbf{\sigma_x =0.333 \ minutes}[/tex]

c.

Given that;

The average number of count per minute = 3

The value of X such that P(X < x) = 0.95 can be calculated as;

[tex]\int \limits ^x_0 \lambda e^{-\lambda t}= 0.95[/tex]

[tex]3\int \limits ^x_0 \lambda e^{3 t}= 0.95[/tex]

[tex]\bigg [ -e^{3t}\bigg ]^x_0 = 0.95[/tex]

[tex]e^{3t} = 1-0.95[/tex]

-3x = ㏑ (0.05)

-3x = - 2.9957

x = -2.9957/ -3

x = 0.9986

The value of x = 0.9986

Answer:

a) 3

b)3

c) 8.9872

Step-by-step explanation:

a) According to the question, mean is 3.

b) Since it is an exponential distribution, standard deviation equals to mean. Therefore, the answer is 3.

c) P[x<X]=0.95

f(x)= λ*e^(-λ*x)

∫f(x)dx, 0 to x

mean = 1/λ =3. So, λ= 1/3.

∫(1/3)*e^(-x/3)dx= 1/3*e^(-x/3)/(-1/3)=-e^(-x/3) 0 to x

-e^(-x/3)+1 = 0.95

-e^(-x/3)=-0.05

x/3=ln(0.05)

x=ln(0.05)*3= 8.9872

Answers

Answer:

The chosen topic is not meant for use with this type of problem. Try the examples below.

2 = |3x|

−4/5x + 1/25 = 0

3x = 4 − x

Answer

Step-by-step explanation:

This has to be equal to something in order to solve it. I'm going to guess that it is equal to 0

(3x-15)(2x+7) = 0

That means that

3x - 15 = 0

3x = 15

x = 15/3

x = 5

or

2x + 7 = 0

2x = - 7

x = -7/2

x = - 3.5

The only other thing I can think of that this could equal is multiplying the two binomials together.

3x * 2x = 6x^2

3x*7 = 21x

-15*2x = - 30x

-15 * 7 = - 105

6x^2 - 7x - 105

But that does not solve for x.
