What do you think x equals?

Mathematics

zmey [24]2 years ago

Answer:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

The daily high temperature on October 31 in a certain city is normally distributed with µ = 50 and σ = 8 . What is the probabili
tatyana61 [14]

Answer:

0.5328

Step-by-step explanation:

µ = 50

σ = 8

We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

P(46 < x< 58)

Formula : Z=\frac{x-\mu}{\sigma}

at x = 46

Z=\frac{46-50}{8}

Z=-0.5

Refer the z table for p value

p value = 0.3085

at x = 58

Z=\frac{58-50}{8}

Z=1

Refer the z table for p value

p value = 0.8413

P(46 < x< 58)=P(x

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328

The length of a rectangle is 2 m longer than its width. if the perimeter of the rectangle is 40 m , find its area.
vredina [299]
L=w+2 and 2w+2l=40

Substitute length for w+2 in perimeter formula.

2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9

l=w+2
l=9+2
l=11

a=lw=11*9=99 meters
