Answer:  B. 91,390

Step-by-step explanation:

The combination of n things taken m things at a time is given by :-

^nC_m=\dfrac{n!}{m!(n-m)!}

Given : The total numbers in lottery = 40

The number of correct numbers to win the lottery = 4

Now, the combination of 40 numbers taken 4 correct numbers at a time is given by :-

^{40}C_{4}=\dfrac{40!}{4!(40-4)!}\\\\=\dfrac{40\times39\times38\times37\times36!}{(24)(36!)}=91,390

Hence, there are 91,390 different 4 number combinations .

By what number (5/4)^6 should be divided to get (25/16)^8?
Naya [18.7K]

Answer:

X=(5/4)^-10

Step-by-step explanation:

(5/4)^6÷x=(25/16)^8

(5/4)^6÷x=(5/4)^16

1/X==(5/4)^16÷(5/4)^6

X=(5/4)^6÷(5/4)^16

X=(5/4)^-10

So the value of X is (5/4)^-10

A number d minus is less than -1
katrin [286]

\boxed{d-4

<h2>Explanation:</h2>

Hello! Recall you need to write complete questions in order to find exact answers. So in this problem I'll assume the question is:

<em>A number d minus 4 is less than -1</em>

<em />

So it is easy to know that we need to write an inequality here because of the words "less than", which implies that we must use the symbol <. So let's solve this step by step.

Step 1. A number d minus 4.

This statement includes the word "minus", so we need to use the symbol (-). Therefore:

d-4

Step 2. A number d minus 4 is less than

As we said above, here we need to use the symbol (<). So:

d-4

Step 3. A number d minus 4 is less than -1

Finally, we get:

d-4

Which set of ordered pairs gives the polygon shown?
makvit [3.9K]
The correct answer is B.

Explanation
Since each interval mark is 1/4 of a unit, we will write this as 0.25.  For the first point, 4 interval marks to the left of the y-axis makes it a negative number; 4(0.25) = 1; this makes the x-coordinate of this point -1.  2 interval marks above the x-axis makes it positive; 2(0.25) = 0.5; this makes the y-coordinate 0.5.  This makes the first ordered pair (-1, 0.5).

The second point is on the y-axis.  This makes the x-coordinate 0.  It is 5 intervals above the x-axis; this makes it positive.  5(0.25) = 1.25 will be the y-coordinate, making the point (0, 1.25).

The third point is 3 intervals to the right of the y-axis; this makes it positive, and 3(0.25)=0.75 for the x-coordinate.  It is 3 intervals below the x-axis; this makes it negative, and 3(0.25) = 0.75, making the y-coordinate -0.75.  This puts the third point at (0.75, -0.75).
