Have a look at the first elements of each point:  {3, 0, 1, -2, 2}.  Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.

<u>answer:</u> it's a function

<u>explanation:</u> the reason why it's a function is when the x's are NOT repeating itself. when it's not a function, it the x's ARE repeating itself.

Solve for b: A= (h(a+b))/2
tresset_1 [31]

A= (h(a+b))/2

multiply each side by 2

2A =  (h(a+b))

divide each side by h

2A/h = a+b

subtract a from each side

2A/h -a = b

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000
Elis [28]

Answer:

84.13% probability a particular tire of this brand will last longer than 57,100 miles

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 60000, \sigma = 2900

What is the probability a particular tire of this brand will last longer than 57,100 miles

This is 1 subtracted by the pvalue of Z when X = 57100. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{57100 - 60000}{2900}

Z = -1

Z = -1 has a pvalue of 0.1587

1 - 0.1587 = 0.8413

84.13% probability a particular tire of this brand will last longer than 57,100 miles

Use the formula h=16t2, where t is time in seconds and h is the distance in feet traveled by a free-falling body or object to so
aksik [14]

Answer:

The time required is 15.97 second.

Step-by-step explanation:

Consider the provided information.

A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.

First find the distance between skywalk and canyon floor by using Pythagorean theorem.

Distance between skywalk and canyon's edge = \sqrt{4080^2+90^2}

Distance between skywalk and canyon's edge = 4080.99

Substitute h = 4080.99 in the provided formula.

4080.99=16t^2

t^2=255.062

t=15.97

Hence, the time required is 15.97 second.

refer back to the first problem on Tuesday,A scale of a map is 1 in:125ft,jon lives 250 feet away from max.how many inches separ
pishuonlain [190]

Answer:

2 inches

Step-by-step explanation:

The scale means 1 inches on map equal 125 feet in real life

<em>We know in real life Jon lives 250 ft away from Max. 250 is twice of 125, hence in map</em>, it should be 1*2=2 inches.

On the map, it is 2 inches from Jon's home to Max's home.
