Answer 1

Answer:

the first box is "two or more 1s"

the second box is "0.13"

Step-by-step explanation: Im a K12 Student

Answer 2

The probability that 2 or more out of 6 packs will have an all-star card is given by the equation P = 0.1333

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that 2 or more out of 6 packs will have an all-star card be P

The probability of finding an all-star card in a game pack is 12.5 %

The student has pointed that 1 represent a pack with an all-star card and 2 through 8 represent a pack without an all-star card

The test results are given in set A = { 561673, 366468, 314255, 361362, 838443, 126285, 257231, 768551, 652585, 468113, 123711, 322764, 487626, 783134, 384664 }

The number of trials that represent that 2 or more out of 6 packs have an all-star are = { 468113 , 123711 }

Therefore , the probability is given as

Probability that 2 or more out of 6 packs will have an all-star card P = 2/15

On simplifying the equation , we get

Probability that 2 or more out of 6 packs will have an all-star card P = 0.133

Hence , the probability is 13.33 %

Find the area of a parallelogram....

Answers

The area of a parallelogram is ...
  A = bh
Substituting the given values, you have
  A = (3x +5)(7x -1)
We presume you want the product multiplied out. Use the distributive property for that.
  A = 3x(7x -1) +5(7x -1)
  A = 21x² -3x +35x -5
  A = 21x² +32x -5

The area of the parallelogram is 21x² +32x -5.

Which of the following shows of the slope of the line and one point on the line?

A. 6/5 and (-3, 1)
B. 5/6 and (1, -3)
C. 5/6 and (-3, 1)
D. -6/5 and (1, -3)

Answers

Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.

Find f(x) if it is known that f(3k)=3k+7.

Answers

f(3k)=3k +7   Equals    9k+7.  So 9k+7 would be the Answer.

Since f(3k) = 3k+7  (Equation 1)

We have to determine the value of f(x).

That is we have to replace 3k by x,

3k = x

Substituting the value of 3k in equation 1.

So, f(x) = x + 7

Therefore, f(x)=x+7 is the required function.

Robin’s scores: 99, 108, 102, 107, 119 Evelyn’s scores: 125, 137, 138, 145, 145 Find and compare the medians of the data sets. Do the medians support your conclusion that Robin is winning the game?

Answers

To find the median, just sort the numbers from least to greatest and find the number in the center. 

Robin's scores: 99, 102, 107, 108, 119. Median is 107. 

Evelyn's scores: 125, 137, 138, 145, 145. Median is 138. 

The median from Evelyn's scores is greater than the median from Robin's. Therefore, the medians do NOT support the conclusion that Robin is winning the game. 

Answer:

The median score for Robin is 107. The Median Score of Evelyn is 138. The medians are the same as the means, so the same conclusion that Robin is winning will be drawn.

Kristen invests $5,745 in a bank. The bank pays 6.5% interest compounded monthly. How long must she leave the money in the bank for it to double? Round to nearest tenth of a year.

Answers

To solve this we are going to use the compounded interest formula: [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where
[tex]A[/tex] is the final amount 
[tex]P[/tex] is the initial investment
[tex]r[/tex] is the interest rate in decimal form 
[tex]t[/tex] is the time in years 

We know that initial investment is $5,745, so [tex]P=5745[/tex]. We also know that Kristen wants his investment to double, so [tex]A=2*5745=11490[/tex]. Now, to convert the interest rate to decimal form, we are going to divide the rate by 100%: [tex]r= \frac{6.5}{100}=0.065 [/tex]. Since the interest is compounded monthly, it is compounded 12 times per year: therefore, [tex]n=12[/tex]. Now that we have all the information we need, lets replace the values in our formula and solve for [tex]t[/tex]:
[tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
[tex]11490=5745(1+ \frac{0.065}{12})^{12t} [/tex]
[tex] \frac{11490}{5745} =(1+ \frac{0.065}{12})^{12t}[/tex]
[tex]2=( \frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=ln(\frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=12tln(\frac{2413}{2400} )[/tex]
[tex] \frac{ln(2)}{12ln(\frac{2413}{2400} )} =t[/tex]
[tex]t=\frac{ln(2)}{12ln(\frac{2413}{2400} )}[/tex]
[tex]t=10.7[/tex]

We can conclude that she must leave the money for 10.7 years in the bank for it to double.

Solve the equation (x-5)1/2+5=2

Answers

The first thing we are going to do for this case is to rewrite the equation correctly:
 ((x-5) ^ (1/2)) + 5 = 2
 Clearing x we have:
 (x-5) ^ (1/2) = 2-5
 (x-5) ^ (1/2) = -3
 x-5 = root (-3)
 x-5 = i * root (3)
 x = 5 + i * root (3)
 Answer:
 The value of x is given by:
 x = 5 + i * root (3)
(x - 5)1/2 + 5 = 2 
(x - 5)1/2 + 5 - 5 = 2 - 5
(x - 5)1/2 = -3
1/2x - 2.5 = -3
1/2x - 2.5 + 2.5 = -3 + 2.5

Answers

The larger the standard deviation, the more spread out the data values will be. A smaller standard deviation, and the values are more closely grouped together. The variance is equal to the standard deviation squared. In terms of symbols
V = s^2
where V = variance and s = standard deviation
So the variance can also be used to determine how grouped or spread out the data values are

------------------------------------------

The z score tells us where this score is located in terms of the group. If the z score is positive, then it is above the mean. If the z score is negative, then it is below the mean. The further the z score is from zero, the further the raw score is from the mean. A score of z = 0 is right at the mean.

The functions have the same initial value is correct

"The functions have the same rate of change" is wrong because as we can see, the table goes up by 10, however, the graph goes up by 15

"Both functions are the same" is also wrong, we already proved they have a different slope, how could they possibly be the same?

"The rate of change for Tour 1 is greater" is also wrong because tour 2 goes by 15, which is greater than 10.

"The functions have the same initial value is correct because as we can see on the graph(tour 2), the y-intercept is 35, using the slope on the tab;e(tour 1) we can calculate that when x is 0, the y-value is 35, which means both of the tours has a y-intercept of 35, therefore, this is the correct choice

It's possibly "The functions have the same rate of change."

Explanation: Alright let's do answer of elimination. It cannot be "Both functions are the same" Due to the fact that for one person in Tour 1 is 45 dollars while for Tour 2 is 50. It cannot be "The functions have the same initial value. Since for initial value it's kind of like a constant. For example for 1 person it would be 20 dollars for 2 it would be 40 and so on. It cannot be the last one since  rate of change is obviously different. I don't think I have to go into that.
