Answer:

.0615

Step-by-step explanation:

p=.11

n=149

np=16.39 (which is the mean)

x<11 so 10.5...-999

σ= \sqrt{16.39(1-.11)} =3.81930622

normalcdf(-999,10.5,16.39,3.81930622)

= .0615167786

Suppose that the auto loans from a bank are normally distributed with a mean of $23,334 and a standard deviation of 3,412. what
UkoKoshka [18]
To illustrate the information in the correct syntax:
X~N(23334, 3412²)
What we're being asked to find is P(X ≤ 26000).
In order to do this, we need to convert this value into one we can look up on the table for the standard normal distribution (Z).
To do this we use the formula:
Z = (X - μ)/σ
Z = (26000 - 23334)/3412 = 0.7813599... ⇒ 0.78
We can say:
P(X ≤ 26000) = P(Z ≤ 0.78) = 0.7823

Find the minimum product of two numbers whose difference is 17. <br> what are the numbers?
Marysya12 [62]

A number is an arithmetic value that is used to represent a quantity and calculate it. The two numbers will be 17 and 0, so the product of the two is minimal.

<h3>What are Numbers?</h3>

A number is an arithmetic value that is used to represent a quantity and calculate it. Numericals are written symbols that represent numbers, such as "3."

Given the difference between the two numbers is 17. Let the first number be zero, then the second number will be 17. Thus, the product of the two numbers will be 0, which is the minimum.

If the first number is further increased such as 1, then the other number will be 18, and the product of the two will be 18, which is greater than zero.

Hence, the two numbers will be 17 and 0, so the product of the two is minimal.

Geometry:Finish the coordinate rule to describe the transformation in the image.
stira [4]

It looks like a reflection over the y-axis. There's a formula you can use when doing reflections over the y-axis, (x,y) is going to become (-x, y) thats also the coordinate rule I think.

If you apply that rule to each point you should get the reflected image.

G- (1, 3) then (-x,y) to get (-1,3)

E- (1, 2) then (-x,y) to get (-1, 2)

V- (5, 1) then (-x,y) to get (-5, 1)

X- (3, 3) then (-x,y) to get (-3, 3)
