Answer:

-5

Step-by-step explanation:

counting is like backwards in negatives so a +5 is slow and a +25 is high but in negatives its the opposite because you are missing that many

I dont really know who to explain it but I hope this helps

The midpoint of AB is M(-1,7). If the coordinates of A are (4,8), what are the<br> coordinates of B?

miskamm [114]

Answer:

B (-6,6)

Step-by-step explanation:

For two points (a,b) and (c,d), the co-ordinate of the midpoint of the line joining the points is ((a+c)/2 , (b+d)/2)

Let, co-ordnate of B is (x,y)

So, (4+x)/2 = -1 ; (8+y)/2 = 7

=> x = -6 ; => y = 6

If y=24 when x=6, find y when x=-4.

Mkey [24]

Answer:

$\huge\boxed{y=-16}$

Step-by-step explanation:

We have to note that this represents a proportional relationship. This means that every time x increases by 1, y will increase by a proportional value.

In order to solve for proportions, we can create a proportion fraction which basically puts two variables over each other. Let's put x over y.

$\frac{x}{y}$

We know that in the first fraction, x=6 and y=24.

$\frac{6}{24}$

And we know that x=-4 but we have an unknown y value.

$\frac{-4}{y}$

We can now set these proportions equal to each other and solve for the missing y using cross products.

$\frac{6}{24}=\frac{-4}{y}$
$y = (24 \cdot -4) \div 6$
$y = -96 \div 6$
$y = -16$

Hope this helped!

The odometer (which measures the distance traveled) on Mario’s parent’s car reads 28,882 when his father fills up. Since Mario’s

a. The next 5 palindromes for the car's odometer are <u>28982, 29092, 29192, 29292, and 29392 miles</u>.

b. After setting the trip's odometer to 0 to determine the number of miles the trip is, the next 5 palindromes for the trip are <u>11, 22, 33, 44, and 55 miles</u>.

c. The next time that both the car's odometer and the trip's odometer will be a palindrome is when the car's odometer reads <u>39993</u>, while the trip's odometer reads <u>11111</u>.

<h3>What is a palindrome?</h3>

A palindrome is a word, phrase, or sentence that remains the same when spelled or written backward or forward.

As a Greek word, palindrome combines 'again' (Palin) and 'to run' (Drom).

Thus, once a word or number reads the same backwards as it is forwards, it is a palindrome.

Suppose that an airline uses a seat width of 16.5 in. Assume men have hip breadths that are normally distributed with a mean of

Alexxx [7]

Answer:

a) 0.018

b) 0

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 14.4 in

Standard Deviation, σ = 1 in

We are given that the distribution of breadths is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(breadth will be greater than 16.5 in)

P(x > 16.5)

$P( x > 16.5) = P( z > \displaystyle\frac{16.5 - 14.4}{1}) = P(z > 2.1)$

$= 1 - P(z \leq 2.1)$

Calculation the value from standard normal z table, we have,

$P(x > 16.5) = 1 - 0.982 = 0.018 = 1.8\%$

0.018 is the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.5 in.

b) P( with 123 randomly selected men, these men have a mean hip breadth greater than 16.5 in)

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

P(x > 16.5)

$P( x > 16.5) = P( z > \displaystyle\frac{16.5-14.4}{\frac{1}{\sqrt{123}}}) = P(z > 23.29)$

$= 1 - P(z \leq 23.29)$

Calculation the value from standard normal z table, we have,

$P(x > 16.5) = 1 - 1 = 0$

There is 0 probability that 123 randomly selected men have a mean hip breadth greater than 16.5 in
