the surface area S of the red solid is 90m^2

Step-by-step explanation:

The computation of the surface area of the red solid is shown below:

First find the scale factor i.e.

= 6 ÷ 4

= 1.5

Now the surface area of the red solid is

= 40 × 1.5 × 1.5

= 90m^2

Hence, the surface area S of the red solid is 90m^2

Answer:

54°both are 73°x = 12

Step-by-step explanation:

Some useful relations are ...

  A triangle inscribed in a semicircle is a right triangle.

  Acute angles in a right triangle are complementary.

  An inscribed angle is half the measure of the arc it intercepts.

  The sum of arcs around a circle is 360°; 180° around a semicircle.

__

1. Arc DF is twice the marked inscribed angle, so is 126°. Arc FE is supplementary to that, so is ...

  arc FE = 180° -126°

  arc FE = 54°

Alternate solution: arc FE is twice angle D, which is the complement of 63°.

  2(90° -63°) = 2(27°) = 54° = arc FE

__

2. Arc GJ = 360°-68° -31° -115° = 146°

  angle GHJ = angle GIJ = 146°/2 = 73°

__

3. arc UT = 2(90° -43°) = 94°

  9x -14 = 94

  9x = 108 . . . . . add 14

  x = 12 . . . . . . . . divide by 9

eight times the reciprocal of a number equals 4 times the reciprocal of 2. find the number

Answers

Answer:

The number is 4

Step-by-step explanation:

Let the number  = 'x'

Reciprocal of 'x' = 1/x

Reciprocal of 2 = 1/2

8 times the reciprocal of 'x' = [tex]8*\frac{1}{x}\\[/tex]

[tex]8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\[/tex]

Now multiply both sides by x

[tex]8*\frac{1}{x}*x = 2*x\\\\8 = 2x[/tex]

Now divide both sides by 2

[tex]\frac{8}{2}=\frac{2x}{2}\\\\4 = x[/tex]

x = 4

Sasha selected a random sample of bivariate data, with a sample size of 30, and calculated a slope of 3.6 for the sample slope of a regression model. Sasha constructed a 95 percent confidence interval to estimate the slope. Alex claims he can construct a confidence interval that is narrower by changing the sample size but keeping all other things the same. Which of the following sample sizes will make Alex's claim true?
A. 10
B. 15
C. 20
D. 25
E. 35

Answers

D or e is the correct answer

The sample size that will make the Alex's claim true is option E. 35.

What is Confidence Interval?

Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.

This means that, if you do your experiment more than once and do resampling, then this is the percentage that the parameters falls within a range.

Sample size of Sasha = 30

She took a confidence interval of 95%.

Alex claims he can construct a confidence interval that is narrower by changing the sample size but keeping all other things the same.

The relation between the sample size and confidence interval is that when the size of sample increases, the confidence interval becomes narrower.

So if the Alex's claim has to be true, sample size must increase.

He can use sample size of 35.

Hence the correct option is E.

In one lottery, a player wins the jackpot by matching all five numbers drawn from white balls (1 through 43) and matching the number on the gold ball (1 through 34). If one ticket is purchased, what is the probability of winning the jackpot? Testir​

Answers

This can be found by finding 44 chosen 5 at a time times 1/32.
That would be
44! / (44-5)!(5!) * 32 =
1 chance in 34,752,256

The probability of winning the jackpot is 1/32728332.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

In one lottery, a player wins the jackpot by matching all five numbers drawn from white balls (1 through 43) and matching the number on the gold ball (1 through 34).

Total number of white balls = 43

Number of combinations of selecting 5 from 43 = 43C₅  

                                                                                = 43! / (5! × 38!)

                                                                                = 962598

Total number of gold balls = 34

Number of combinations of selecting 1 from 34 = 34C₁

                                                                               = 34

Total number of ways of selecting 5 white balls and 1 gold ball = 962598 × 34 = 32728332

There is only 1 way for which the player wins the jackpot.

Probability of winning the jackpot = 1/32728332

Hence the required probability is 1/32728332.

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which line from the text best explains the main reason memories change?A: Most likely, you could describe the room very generally.B: The more a witness's account is told, the less accurate it isC: The next time you are retelling a story, notice what you add D: You may also notice that you drop certain details Consider the following intermediate chemical equations.P(s)+3O(g) ---> PO(s) H = -1640kJPO(s) ---> P(s)+5O(g) H = 2,940.1 kJWhat is the enthalpy of the overall chemical reaction PO(s)+2O(g) ---> PO(s)A.) -4,580 kJB.) -1,300 kJC.) 1,300 kJD.) 4,580 kJ Use the order of operations to solve for C when n = 5.C = 7(4n + 2) - 8Use order of operations to solve for C when n = 5.C = 45 - 3n Which trade networks connected to the Byzantine Empire? true or false,, The juvenile and criminal justice systems are the same, only the ages of the offenders differ. what does the government owe its people ?
