The first dropdown box answer is "reflection over the y axis"

See the attached image.

Note how corresponding points simply have the x coordinate negated. For example, A and M correspond
A = (2,8)
M = (-2,8)
The only difference between these two points is the x coordinate is positive for A, and negative for M

The same applies for B and N, C and O, etc etc

Whenever you negate x coordinates only, a reflection over the y axis occurs. This is the rule (x,y) ---> (-x,y)

-----------------------------------------------------------------------------------

The second dropdown box answer is the second choice

We can see this by adding 3 to the x coordinate of point M to go from -2 to 1 (-2+3 = 1). So the answer must have point V with an x coordinate of 1. The only answer choice that fits is choice 2.

A rubber ball has a radius of about 2.86 in. Can the ball be packaged in a box shaped like a cube with a volume of 125 in3?

Sonja [21]

volume of the ball = 4/3 * PI *r^3 =

4/3 * 3.14 * 2.86^3 = 97.99 cubic inches

this is less than the volume of the box, so yes it will fit

1. The probability of telesales representative making a sale on a customer call is 0.15.

Mumz [18]

Answer:

$n = 33$

$n = 19$

Step-by-step explanation:

From the question we are told that

The probability of telesales representative making a sale on a customer call is $p = 0.15$

The mean is $\mu = 5$

Generally the distribution of sales call made by a telesales representative follows a binomial distribution

i.e

$X \~ \ \ \ B(n , p)$

and the probability distribution function for binomial distribution is

$P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}$

Here C stands for combination hence we are going to be making use of the combination function in our calculators

Generally the mean is mathematically represented as

$\mu = n* p$

=> $5= n * 0.15$

=> $n = 33$

Generally the least number of calls that need to be made by a representative for the probability of at least 1 sale to exceed 0.95 is mathematically represented as

$P( X \ge 1) = 1 - P( X < 1 ) > 0.95$
