Answer:

11.89

Step-by-step explanation:

let x be the increases length

now (6.4+x)(4+x)(10.5+x) = 2*250

solving this we get x = 1.39

so the largest dimension is 10.5+ 1.39 = 11.89

João claims he can read minds. His friend Pedro asked him to guess a number he was thinking of between 1 and 7 (inclusive). João

Ksju [112]

It can be deduced that the probability of having 4 or more correct guesses will be 0.0296.

<h3>How to calculate the probability</h3>

From the given information, the null hypothesis is p = 1/7 and the alternate hypothesis is p>1/7. In this case, the mind reader gets a 4 out of 9 chances.

In order to test the hypothesis, simulations for 10000 cases were run with a probability of the correct answer being 1/7.

In this case, the p-value is the probability of correct answers that are greater than 4, assuming the null hypothesis is true. Here the p-value is 0.0296.

Also, the significance level to reject the hypothesis is less than 0.01. Since p > 0.01, we then fail to reject the hypothesis. Therefore the null hypothesis stands and Joao is not a mind reader.

Sketch these cartesin products on the x-y plane R^2<br><br> 14. 11,21x1,1.5,2

ale4655 [162]

Answer:

$\left\{11, 21\right\} \times \left\{1, 1.5, 2\right\} = \left\{ (11, 1), (11, 1.5), (11, 2), (21, 1), (21, 1.5), (21, 2)\right\}$

Step-by-step explanation:

The Cartesian product between two discrete sets, is given by all possible ordered pairs originated with the combinations of the elements of the two sets, thus the requested Cartesian product is:

$\left\{11, 21\right\} \times \left\{1, 1.5, 2\right\} = \left\{ (11, 1), (11, 1.5), (11, 2), (21, 1), (21, 1.5), (21, 2)\right\}$

$A = (11, 1)\\B = (11, 1.5)\\C = (11, 2)\\D = (21, 1)\\E = (21, 1.5)\\F = (21, 2)\\$

What is an equation of a line, in point slope form that passes thru (1 -7) and has a slope of -2/3

Allisa [31]

Answer:

y +7 = -2/3(x - 1)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line

y - -7 = -2/3(x - 1)

y +7 = -2/3(x - 1)
