Answer:

[tex]Probability = 0.50[/tex]

Step-by-step explanation:

Given

[tex]Probability = 50\ 50\ chance[/tex]  

[tex]Successful\ Bids = 80\%[/tex]

[tex]Unsuccessful\ Bids = 35\%[/tex]

Required

Determine the probability before the request of past experience

In this case, we only consider the 50 50 chance probability

[tex]Probability = \frac{50}{50 + 50}[/tex]

[tex]Probability = \frac{50}{100}[/tex]

[tex]Probability = 0.50[/tex]

1a. -4 3/5

1b. -4 3/5

2. 33

Step-by-step explanation:

1a. -4 4/5 + 1/5 = -4 3/5

1b. -4 2/5 + (-1/5) = -4 3/5

2. (-16 -35) + 18 = -33

You would need to draw the number 33 to get a score of 0.

Answer:

17.70-2.90=14.80

14.80/1.85=8

He could buy a maximum of 8 chip bags.

bags of chips = x

17.70-2.90/1.85≥x

the baby would be weigh 0.17 kilograms

Answer:

There are significant differences among the mean tensile strengths for different temperatures.

Step-by-step explanation:

A one-way ANOVA is used to test whether there is significant difference between the means for more than two groups.

The hypothesis can be defined as follows:

H₀: There is no difference between the means, i.e. [tex]\mu_{1}=\mu_{2}=\mu_{3}=\mu_{4}[/tex].

Hₐ: There is a significant difference between the means, i.e.at least one of the mean is different.

Use MS-Excel to perform the analysis of variance.

Go to Data → Data Analysis → Anova: Single Factor.

A dialog box will open.

Enter the data and enter Alpha as 0.05.

Press OK.

The output is attached below.

The F-value is, 8.40458.

The p-value of the test is, 0.00139.

Decision Rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected.

p-value = 0.00139 < α = 0.05

The null hypothesis will be rejected at 5% level of significance.

Concluding that there are differences among the mean tensile strengths for different temperatures.

Answer:

Mode = 7

Median = 6

Mean = 5.2

Range = 7

Step-by-step explanation:

[tex]3 \: ,7 \:,2 \:,4 \:,7 \:,5, \:7\:,1,8 \:,8[/tex]

a) Write down the mode

Mode is the number that appears the most in a given set of data

[tex]Mode = \:7[/tex]

7 appears thrice , 8 appears twice and rest appear once.

b) Median

Median is the middle number of a given set of data when arranged in order of least to largest.

[tex]1,2 , 3 ,4,5, 7,7,7,8,8\\\\=1),2),3),4)5,7,(7,(7,(8,(8\\\\= \frac{5+7}{2}\\ \\= \frac{12}{2}\\ \\= 6[/tex]

c. Mean

Mean is the sum of all values divided by the number of given values

[tex]\frac{1+2+3+4+5+7+7+7+8+8}{10} \\\\= \frac{52}{10} \\\\= 5.2[/tex]

d)Range

Range is the difference between the highest value and the lowest vale in a given set of data.

[tex]Highest \:value =8\\Lowest\:value = 1\\\\Range = 8-1\\\\=7[/tex]

Answer:

Step-by-step explanation:

448 rows

28 flowers in each

Answer:

16 rows

Step-by-step explanation:

448 :28 =16 rows

Answer:

From the question we are told that

  The  equation is  [tex]2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0[/tex]

Generally the goal of this solution is to prove that the implicit solution of the differential  equation above is  [tex]ln(x^2 + 11) + csc(y) = C.[/tex]

First Step  

    Differentiate the solution with respect to  x  

   [tex]0  = \frac{2x}{ x^2 + 11}  + [-cot * csc(y) ]\frac{dy}{dx}[/tex]

=> [tex]0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin(y) }* \frac{1}{sin(y)} ]\frac{dy}{dx}[/tex]  

=>  [tex]0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin^2(y) }]\frac{dy}{dx}[/tex]

=>  

multiply through by  [tex]sin^2(y)[/tex] , [tex] x^2 + 11[/tex], [tex]dx[/tex]

So

=> [tex]2 x (sin^2(y) dx + [-cos(y) (x^2 + 11)]dy = 0[/tex]

Looking at the equation obtained we see that it is equivalent to the differential  equation hence  the implicit solution of [tex]2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0[/tex] is   [tex]ln(x^2 + 11) + csc(y) = C.[/tex]

Answer:

m = 4

Step-by-step explanation:

solve for m 3+5m = 8m-9

3+5m = 8m-9

  -5m   -5m

3 = 3m-9

+9       +9

12 = 3m

/3    /3

4 = m

m = 4

Answer:

60n+36

Step-by-step explanation:

12*5n+12*3=60n+36

Hey there!

(5n+3)12 is the same as

12(5n+3)

because we multiply 12 times 5n and 3:

60n+36

And we can't simplify this any further, because 60n and 36 aren't like terms.

Hope everything is clear.

Let me know if you have any questions!

Answer:

Factors of 15 include 3 and 5; multiples of 15 include 30, 45, 60, etc.

Step-by-step explanation:

Factors and multiples are different things. But they both involve multiplication. Factors are what we can multiply to get the number. Multiples are what we get after multiplying the number by an integer

Answer:

  (3x -10)(x -2)

Step-by-step explanation:

You want to start by finding two factors of 3·20 = 60 that have a total of -16.

  60 = (-1)(-60) = (-2)(-30) = (-3)(-20) = (-4)(-15) = (-5)(-12) = (-6)(-10)

The last of these factor pairs (-6, -10) have a total of -16, so these are what you need to rewrite the middle term:

  3x² -6x -10x +20

Now, you can factor by pairs:

  = 3x(x -2) -10(x -2)

  = (3x -10)(x -2) . . . . your factored trinomial

Step-by-step explanation:

She has 36 sold 9 so 36-9=27

Answer:

It is impossible to find two points that are both 1 inch and 1.5 inches from the point A simultaneously as shown in the following proof

From segment addition postulate given a point C that is between the points of a segment AB, we have;

AC + CB = AB

Therefore, where AC = 1 inch and CB = 1.5 inches, we have;

AC + CB = 1 inch + 1.5 inches = 2.5 inches ≠ AB = 3 inches

However it is possible to find two points in which one of the points is 1 inch from the point A while the other point is 1.5 inches from the point B

the answer 18.0008

Step-by-step explanation:

Answer:

Step-by-step explanation:

1st step, we use the distance formula. After plugging in we simplify.

2-7 = 5 / 6-18 = 12.

Then we are left with 5^2 and 12^2

5x5 = 25 and 12x12 is 144

we added them up and get 169

The square root of 169 is the answer to the distance.

Answer:

$700

Step-by-step explanation:

Given that:

Cost of desktop PC 10 years ago = $6000

Cost of desktop PC 2 years ago = $300

Linear model applies.

To find the rate of decrease per year, we need to find the slope.

One quantity is cost of PC here and second quantity here is number of years.

[tex]\text{Rate of decrease per year = }\dfrac{\text{Change in Price}}{\text{Change in Number of years}}[/tex]

[tex]\Rightarrow \dfrac{6000-300}{10-2}\\\Rightarrow \dfrac{5700}{8}\approx \bold{\$700}[/tex]

So, the answer is:

There is a decrease of $700 per year.

OR

Rate of decrease per year is $700.

700$
