Answer:

12/13

Step-by-step explanation:

A probability is the number of desired outcomes over the total number of outcomes.

Assuming that this is a standard deck of playing cards, there will be 52 cards, and there will be 4 "4" cards.

First, find the number of desired outcomes, and put it over the total number of outcomes.

Out of the total number of outcomes (52), there are 4 outcomes that are not wanted, hence the equation is:

52 - 4 = 48

So out of the 52 possible outcomes, 48 are desired. Set up the fraction and

simplify:

48/52

/4   /4

= 12/13

Answer:

Step-by-step explanation:

Let x^3 = y

f(x) = 27(x^3)^2 + 1524(x^3) + 125

f(x) = 27 y^2 + 1524y + 125

You can now put this into the quadratic formula. When you do, you get

(y + 0.0821)(y+56.3623) = 0

So now you substitute x^3 into this

(x^3 + 0.0821)(x^3 + 56.3623)

x^3 + 0.0821 = 0

x^3 = - 0.0821

cuberoot x^3 = cube root 0.0821

x = - 0.4346

x^3 = - 56.3623

x = - 3.8341

Answer:

Step-by-step explanation:

If the price od 1 scallions weight 6ounces, 6 bunches of scallion wwill weight 6(6) i.e 36 ounces.

Cost price = 36 ounces.

%Loss = 19%

Get the selling price

%Loss = 36-Sp/36 * 100

19 = 36-Sp/36 * 100

0.19 = 36-Sp/36

0.19 * 36 = 36-Sp

7.41 = 36-Sp

Sp = 7.41 + 36

Sp = 43.41 ounces

If after cleaning you have 29.5 ounces of cleaned scallions, then then;

% gain = 43.41-29.5/29.5 * 100

%gain = 13.91/29.5 * 100

%gain = 47.2%

Hence the yield percent id 47.2%

Complete Question

The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims will be more depressed, so you formulate the null and alternative hypotheses as:

[tex]H_o: \ \ \mu_{victims} - \mu_{bully-victims} = 0H1: \ \ \mu _{victims} - \mu_{bully-victims} \ne 0[/tex]

You conduct an independent-measures t test. Given your null and alternative hypotheses,

this is a ________ [ Select ]                       ["two-tailed", "one-tailed"]         test.

The degree of freedom is __________   [ Select ]       ["46", "48", "24", "22"]    

and for an alpha of .01, the critical t is +/-    _________ [ Select ]                       ["2.704", "2.021", "1.684"]    

In order to calculate the t statistic, you first need to calculate the standard error under the assumption that the null hypothesis is true. In order to calculate the standard error, you first need to calculate the pooled variance. The pooled variance is   ________ [ Select ]                       ["72.8696", "145", "0.3756", "71.3201"] .

The standard error is   ___________ [ Select ]             ["2.4664", "2.5572", "1.9543", "72.8712"]         .

The t-statistic is _________ [ Select ]                       ["1.95", "2.55", "-1.70", "-2.25"]

Answer:

First Question

 The correct option is  "two-tailed"

Second Question

    The correct option is "46"

Third Question

     The correct option is  "2.704"

Fourth Question

     The correct option is "72.8696"

Five  Question

     The correct option is "2.4664"

Sixth  Question

     The correct option is "1.95"

Step-by-step explanation:

From the question we are told that

   The number of victims is  [tex]n_1 = 25[/tex]

   The sample mean is  [tex]\= x_1 = 25.3[/tex]

   The standard deviation is  [tex]s_1 = 9[/tex]

   The  number of bully victims is  [tex]n_2 = 23[/tex]

   The sample mean is  [tex]\= x_2 = 20.5[/tex]

    The standard deviation is  [tex]s_2 = 8[/tex]

Generally this is a two -tailed test because  from the null and the alternative hypothesis we see that the test is know whether the mean number of victims is significantly more depressed than bully -victims  or significantly  less depressed than bully -victims

Generally the degree of freedom is mathematically represented as  

      [tex]df = n_1 + n_2 -2[/tex]

=>   [tex]df = 25 + 23 -2[/tex]

=>   [tex]df = 46[/tex]

Generally from t distribution table the critical value of  [tex]\alpha = 0.01[/tex] for  a two-tailed test at a degree of freedom of  [tex]df = 46[/tex] is  

      [tex]t_{0.01 , 46} = \pm 2.704[/tex]

Generally the pooled variance is mathematically represented as

     [tex]s^2 = \frac{(n_1 - 1) s_1^2 + (n_2 - 1)s_2^2}{df}[/tex]

=>    [tex]s^2 = \frac{(25 - 1) 9^2 + (23 - 1)8^2}{46}[/tex]

=>    [tex]s^2 = 72.8696[/tex]

Generally the standard error is mathematically represented as

     [tex]SE = s \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]

    [tex]SE = \sqrt{s^2} * \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]

=>   [tex]SE = \sqrt{72.8696} * \sqrt{\frac{1}{25} + \frac{1}{23} }[/tex]

=>    [tex]SE = 2.4664[/tex]

Generally the  test statistics is mathematically represented as

     [tex]t = \frac{\= x_ 1 - \= x_2}{SE }[/tex]

=>   [tex]t = \frac{25.3 - 20.5}{ 2.4664 }[/tex]

=>   [tex]t =1.95[/tex]

To test if bully-victims are more depressed, we have that:

For our test, we consider that:

At the null hypothesis, we test that they have the same scores, that is:

[tex]H_0: \mu_B = \mu_{NB}[/tex]

Which can also be written as:

[tex]H_0: \mu_B - \mu_{NB} = 0[/tex]

At the alternative hypothesis, we test if the score of bully victims is less than the score of non-bully victims, that is:

[tex]H_1: \mu_B < \mu_{NB}[/tex]

[tex]H_1: \mu_B - \mu_{NB} < 0[/tex]

Step-by-step explanation:

The given number is 3.5×10⁶. It is written in scientific form. We can first write it into standard form. There is exponent of 10 is 6.

3.5×10⁶ = 3.5×1000000

We can write 3.5 as 35/10

So,

3.5×10⁶ = (35/10)×1000000

= 3500000

One of the zero of 1000000 is divided by 10 at the denominator. Hence, the exponent in 3.5×10⁶ is 6 while there are 5 zeros in 3500000.

Answer: ∛(3)

Step-by-step explanation:

Suppose that at day 0 the population was A.

at day 3, the population will be: 3*A

at day 6, the population will be 3*(3*A) = A*3^2

then, at day N = 3*n (where n = 0, 1, 2.....) the population will be:

P(N) = A*3^n

Particularly, if we take n = 1/3 we will have:

N = 3*1/3 = 1

This means that this is the first day after the day 0.

P(1) = A*3^(1/3)

(then in day one, the population grow by a factor of 3^(1/3))

N = 2 is when n = 2/3, then:

P(2) = A*3^(2/3)

The quotient between P(2) and P(1) is equal to the growth between day one and day two, this should be the same as the growth between day zero and day one.

A*3^(2/3)/(A*3^(1/3)) = 3^( 2/3 - 1/3) = 3^(1/3)

So we found that the daily growth rate is 3^(1/3) or ∛(3)

The daily growth rate of the bacteria is an illustration of unit rates

The daily growth rate of the bacteria is 0.136

For 22 days, the population of the bacteria triples.

The daily rate is the amount of bacteria each day.

So, we have:

[tex]\mathbf{Daily = \frac{Rate}{Days}}[/tex]

This gives

[tex]\mathbf{Daily = \frac{3}{22}}[/tex]

Divide

[tex]\mathbf{Daily = 0.136}[/tex]

Hence, the daily growing rate of the bacteria is 0.136

Kaleb's server will get a tip of $5.55.

Step-by-step explanation:

In order to find the 20% tip. We must calculate 20% of $27.75.

In other words, $27.75 is the full amount, or total of the order. We can also consider this 100% of the required amount.

So, we need to find 20% of $27.75.

27.75 x 0.20 = $5.55 (which is 20% of 27.75)

Therefore, Kaleb's server will get a tip of $5.55.

Answer:

B

Step-by-step explanation:

RT is the combined segments RE and ET. So:

[tex]RT=RE+ET[/tex]

We know that RT is 43, RE is (4x+7) and ET is 2(3x-4). Substitute:

[tex]43=(4x+7)+2(3x-4)[/tex]

Solve for x. Distribute the right:

[tex]43=4x+7+6x-8[/tex]

Combine like terms:

[tex]43=10x-1[/tex]

Add 1 to both sides:

[tex]10x=44[/tex]

Divide both sides by 10:

[tex]x=4.4[/tex]

So, the value of x is 4.4.

ET is defined as 2(3x-4).

We can find ET by substituting 4.4 for x. So:

[tex]ET=2(3(4.4)-4)=2(13.2-4)=2(9.2)=18.4[/tex]

Hence, our answer is B.
