Answer:
The total number of text messages sent was 27.
Step-by-step explanation:
The monthly cost of the cell phone plan, in function of the number of text messages sent(s) and the number of messages received(r), is given by:
In this question, we have that:
We put this into the equation to find the value of s. So
The total number of text messages sent was 27.
The answer is approximately A ~ 688.19
Let
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag
we know that
b=8+p
p=5
so
b=8+5----> b=13
step 1
Find the total of balls originally in the bag
total =13+5-----> 18
step 2
find <span>the probability that a person will pick a blue ball first
</span>Find P(b)
P (b)=13/18
step 3
Find the probability that a person will pick a pink ball second <span>without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17
step 4
Find </span><span>the probability that a person will pick a blue ball first and then a pink ball without replacement
</span>(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21
the answer is
0.21
Answer:A) 4 roots
b)(-2,0)(-1,0)(1,0)(3,0)
c)(0,-6)
d) down
Step-by-step explanation:
a) there are 4 roots because the max power = the number of turns in a graph
b) plug in 0 for y and solve
c)plug in 0 for x
d)the largest exponent x^4 is negative and since it is even you start and end the opposite way and since it is negative it starts up and goes down
Answer:
240 gallons
Step-by-step explanation:
Let's set up an ratio where g = gallons and m = miles:
20g = 300m
We need the right side of that to be 3600, so multiply both sides by 12:
12(20g) = 12(300m)
Answer: 240 gallons for 3600 miles
