Which of the following best describes how the y values are changing over each interval?
ziro4ka [17]

Answer:

y=ax+b

a=-0.6020457867

b=-2.256697516   <------- There is your value for b, which is the answer to the problem.

You can use these values for a and b to generate an equation in slope-intercept form, which you can then enter under Y= and view the graph.

The mean speed of vehicles along a stretch of highway is 56 mph with a standard deviation of 4 mph. You
Elenna [48]

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

<h3>Z score</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z=\frac{x-\mu}{\sigma }

Where x is raw score, μ is mean, σ is standard deviation

Given that:

σ = 4, μ = 56, hence

for x = 62:

z=\frac{62-56}{4 } =1.5

for x = 47:

z=\frac{47-56}{4 } =-2.25

for x = 56:

z=\frac{56-56}{4 } =0

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

You have 15 pennies in your pocket. Of those pennies, 4 are Canadian. Suppose you pick a penny out of your pocket at random. Fin
vlada-n [284]

Answer:

11/15

Step-by-step explanation:

If 4 out of 15 are Canadian, the ratio of the probability of picking a Canadian is 4/15.  That means that the probability of NOT picking a Canadian is the complement of 4/15 which is 11/15.  Therefore, the probability of not picking a Canadian is the same thing as the probability of picking an American penny which is 11/15.

Postulate: If two lines intersect, then they intersect in exactly one point. true or false
ololo11 [35]

Answer:

Step-by-step explanation:

The given postulate If two lines intersect, then they intersect in exactly one point is true because whenever the two lines intersect they intersect at one point only and we know that a postulate  is a statement that we accept without proof.

The given theorem If two distinct planes intersect, then they intersect in exactly one line is true as theorem is a statement that has been proved and it has been proved that if  two distinct planes intersect, then they intersect in exactly one line.

The figures are drawn to prove them.

An experiment consists of drawing 1 card from a standard​ 52-card deck. What is the probability of drawing a jack?
Andrei [34K]
The probability of drawing a jack from a standard 52 card deck is 7.69%
To get that you divide the number of jacks in a standard (4) by the total number of cards (52). Hope this helps! ✌️
