Answer:
9(s+3.00) + 4s
Step-by-step explanation:
For starters, we s as the basic cost of the shoe. If we buy 4 of those, than it's a simple 4s.
For the other 9 shoes, we have an additional cost of $3. So we will add 3 to s. Since we are buying 9 or those, we will multiple s + 3 by 9. Thus creating the equation above.
First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
What are the next three terms in the sequence? 2, -3, -6, 18, … -108, -1,944, -209,952 -108, 1,944, -209,952 -108, -1,944, 209,9
Semenov [28]
Answer: -108, -1,944, 209,952
Step-by-step explanation:
The the next term in this sequence is being determined by multiplying the last two numbers of the sequence.
Next three terms are;
= -6 * 18
= -108
= 18 * -108
= -1,944
= -108 * -1,944
= 209,952
Answer:
Hours are equal: 7.2
Cost of service are equal: 51.4
Step-by-step explanation:
<u>Happy Paws:</u>
y = 4.5h + 19
<u>Woof Watchers:</u>
y = 5.75h + 10
<u>To solve for the hours are equal:</u>
y = 4.5h + 19
y = 5.75h + 10 (Multiply by -1)
y = 4.5h + 19
-y = -5.75h - 10
0 = -1.25h + 9
-9 = -1.25h
h = 7.2
<u>To solve for when the services are equal:</u>
y = 4.5h + 19
y = 4.5(7.2) + 19
y = 32.4 + 19
y = 51.4
