Answer:
Step-by-step explanation:
3r+5=3(4)+5=17
2+r=2+4=6
17 P6=17*16*15*14*13*12=494,010, 316,800
<u>44%</u>
Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%
Answer: Slope = -8/9 using the slope formula
Step-by-step explanation:
<u><em>To cover a rectangular region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?</em></u>
<u><em></em></u>
<u><em>L=length=15.5 ft; W=width; A=area=>170.5 sq ft</em></u>
<u><em></em></u>
<u><em>L*W=>170.5 sq ft Divide each side by L</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/L</em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/15.5 ft=>11 feet</em></u>
<u><em></em></u>
ANSWER: To cover at least 170.5 sq ft. the width must be at least 11 feet.

Answer
The answer is x^2 + 5x - 6
Step by step explanation
You are given four trinomials, we have to find which trinomial is factorable.
x^2 + 3x - 6 cannot be factored.
x^2 + 5x -6 can be factored.
= (x + 6)(x -1)
The factors are (x-1) and (x - 6)
Other twos are cannot be factored.
The answer is x^2 + 5x - 6
Thank you.
