Twins Ben and Michael claim that they can communicate telepathically. To test the claim, a researcher plans to put the twins in

separate rooms. Five chips of different colors (red, blue, green, yellow, and white) will be placed in a bag. Ben will be blindfolded as he selects a chip at random from the bag. He will then look at the chip and attempt to communicate the color telepathically to his twin Michael, seated in the next room, who will record the color he believes the chip to be. This process will be repeated 50 times. Let p denote the probability that Michael correctly records the color of a chip. State hypotheses for a significance test, letting the alternative hypothesis reflect the possibility that Michael does better than he would by random guessing.
A. H0: p = 1/5Ha: p ≠ 1/5B. H0: p < 1/5Ha: p > 1/5C. H0: p > 1/5Ha: p = 1/5D. H0: p = 1/5Ha: p > 1/5

Answer:

D. H0: p = 1/5Ha: p > 1/5

Step-by-step explanation:

Since alternative is talking about the chances of doing better in one situation over another, then, the equation with the probability of doing better clearly shown by it being greater than the other situation is the right one.

Simplify, choosing the correct answer as a mixed number in lowest terms.<br><br> sqrt of 400/49
Bond [772]

\sqrt{\dfrac{400}{49}}=\dfrac{\sqrt{400}}{\sqrt{49}}=\dfrac{20}{7}=2\dfrac{6}{7}\\\\\text{Used}\ \sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}}

\sqrt{400}=20\ \text{because}\ 20^2=400\\\\\sqrt{49}=7\ \text{because}\ 7^2=49

The line L1 is perpendicular to y=6x+1 and intersects y-axis 3
const2013 [10]

Step-by-step explanation:

Line 1 is a horizontal line so the equation of the line for line 1 is Y = 8   Line 2, first solve the slope of the line using points ( -4 , -5) and ( 0, -2)   M = (y1 – y2) / (x1 – x2) M = ( -5 – ( -2)) / ( -4 – 0) M = ¾ Since its y intercept is at ( 0,-2) B = -2 Y = ¾ x -2   For c and d you should give a point at which the line is perpendicular or parallel

I think that's how to tell someone, right?

What is 4/7 as a decimal
Mademuasel [1]

Answer:

To start off, note that 4/7 is a fraction, and a fraction shows how many parts something is of the whole. Furthermore, decimals are numbers with a decimal point. Both fractions and decimals are used to express partial numbers.

When you want to convert the fraction 4/7 to decimal form, you want to get rid of the fraction divider line and end up with a decimal number.

To get 4/7 in decimal form you simply divide the 4 by 7. Here is the math and the answer:

4 ÷ 7 = 0.57142857

Lourdes plans to jog at least 1.5 miles. Lourdes averages 3.75 mph pace when she jogs write and solve an inequality to find x, t
tamaranim1 [39]

Answer:

Step-by-step explanation:

At least means greater than or equal to, so that is the symbol we will use.  Now, we want the inequality to compare the distance she plans to jog and the amount of time jogged multiplied by the speed, since time times speed equals distance.

Writing this out we get 1.5 ≤ 3.75x

so 1.5 will always be less than or equal to the distance jogged.  let me know if there is something you don't understand.  But after this just solve for x.
