A group of campers walked 4 2/3 miles along a hiking trail. Another group of campers walked 1/4 of that distance with the first group before turning off onto another trail. How many miles did the two groups of campers walk with one another ?
Answer:
14 / 12 miles or 1 1/6 miles
Step-by-step explanation:
A group of campers walked 4 2/3 miles along a hiking trail.
Distance = 4 2/3 miles
Another group of campers walked 1/4 of that distance with the first group before turning off onto another trail.
That is; 1/4 of 4 2/3 miles
How many miles did the two groups of campers walk with one another ?
This is obtained by solving 1/4 of 4 2/3 miles
Converting 4 2/3 to an improper fraction;
4 2/3 = 14 / 3 Miles
1/4 of 14 / 3
1 / 4 * 14 / 3
= 14 / 12 miles or 1 1/6 miles

Find the product. 7/10 X 3/6
Mel paid $15.75 for 6 greeting
cards. Some of the cards cost
$2.50 each, and some cost $3.25
each. Let x represent the number
of cards that cost $2.50 each,
and y represent the number of
cards that cost $3.25 each. This
situation can be represented by
the system x + y = 6 and
2.5x + 3.25y = 15.75. How many
of each type of card did Mei
purchase?
Answer:
Step-by-step explanation:
x + y = 6 -------------(I)
y = 6 -x
2.5x + 3.25y = 15.75 -------------(II)
substitute y = 6 - x in equation (II)
2.5x + 3.25*(6 - x) = 15.75 {Distributive property: a(b +c) =a*b + b*c}
2.5x + 3.25*6 - x * 3.25 = 15.75
2.5x + 19.5 - 3.25x = 15.75
2.5x - 3.25x + 19.5 = 15.75 {Combine like terms}
-0.75x + 19.5 = 15.75
-0.75x=15.75 - 19.5
-0.75x = -3.75
x = -3.75/-0.75
x = 5
Plugin x = 5 in (I)
5 + y = 6
y = 6 - 5
y = 1

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
since you see that the line goes from 10 and does not include it it would be x<10
or because we have to flip sign when multiplying negative -3x>-30

Pending Review Question 7
Alex borrowed $3500 from two banks. One bank charged a simple interest of 8% and another bank
charged a simple interest of 12%. If he paid a total interest of $332 for one year, find the amount that he
borrowed from each bank.
Answer:
$ 2,200 for 8%, $ 1,300 for 12%
Step-by-step explanation:
I=PRT
Let Bank 1 be x
332= x (8%) + (3,500-x) 12%
332= x (0.08) + (3,500-x) 0.12 change the percent to decimal
332= 0.08x + 420 - 0.12x
0.04x= 420-332
x= [tex]\frac{88}{0.04}[/tex]
x= 2,200 (Bank 1)
Bank 2= 3,500-Bank 1
Bank 2= 3,500- 2,200
Bank 2= 1,300

If 13 candy bars cost $19.76, how much do 20 candy bars cost?
Answer:
$30.40
Step-by-step explanation:
to find out how much 20 candy bars would cost, first, we have to find out how much 1 candy bar costs. we do this by dividing $19.76 by 13.
$19.76 ÷ 13 = $1.52
so now we know that one candy bar costs $1.52. now, we multiply this value to 20, to know how much 20 candy bars cost. therefore, we get:
20 × $1.52 = $30.40

Anybody know how to do lowest terms and can teach me how to get the answer to lowest terms questions?
Answer:
Step-by-step explanation:
6/9+x=7/10
x=7/10-6/9
when adding fractions both denominators must be equal, we’ll make them 90
x=(7/10)(9/9)-(6/9)(10/10)
x=63/90-60/90
x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3
x=(3/3)/(90/3)
x=1/30

In parts (a)−(d) below, either use the information given to determine the distribution of the random variable, or show that the information given is not sufficient by describing at least two different random variables that satisfy the given condition. (a) X is a random variable such that MX(t) = e 6t 2 when |t| < 2. (b) Y is a random variable such that MY (t) = 2 2−t for t < 0.5. (c) Z is a random variable such that MZ(t) = [infinity] for t ≥ 5. (d) W is a random variable such that MW (2)
Answer:
a.) X ≈ N (0, 12)
b.) Y ≈ exp(2)
c.) The given distribution is not defined.
d.) Not a standard form of any distribution .
Step-by-step explanation:
Given - In parts (a)−(d) below, either use the information given to determine
the distribution of the random variable, or show that the information
given is not sufficient by describing at least two different random
variables that satisfy the given condition.
To find - (a) X is a random variable such that Mₓ(t) = [tex]e^{6t^{2} }[/tex] when |t| < 2.
(b) Y is a random variable such that [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.
(c) Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.
(d) W is a random variable such that [tex]M_{W}[/tex](2) = 2
Proof -
a.)
As we know that the moment generating function of normal distribution is given by
Mₓ(t) = [tex]e^{ut + \frac{1}{2}t^{2} \sigma^{2}}[/tex]
Now,
Mₓ(t) = [tex]e^{6t^{2} }[/tex]
= [tex]e^{0(t) + \frac{12}{2} t^{2} }[/tex]
⇒μ = 0, σ = 12
Nd it is represented by
X ≈ N (0, 12)
b.)
Moment generating function of exponential function is given by
[tex]M_{Y}[/tex](t) = [tex]( 1 - \frac{t}{\theta})^{-1}[/tex]
Now,
[tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.
= [tex]\frac{1}{\frac{2 - t}{2} }[/tex]
= [tex]\frac{1}{1 - \frac{t}{2} }[/tex]
= [tex]( 1 - \frac{t}{2} )^{-1}[/tex]
And it is represented by
Y ≈ exp(2)
c.)
Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.
The given distribution is undefined.
d.)
[tex]M_{W}[/tex](2) = E([tex]e^{2w}[/tex] )
= [tex]\int\limits^{-\infty}_{\infty} {e^{2w} f(w) } \, dw[/tex]
= 2
It is not the standard form of any distribution.

What is the percent of increase from 75 to 87?
Answer:
16 percent
Step-by-step explanation:
75 is the old value and 87 is the new value. In this case we have a positive change (increase) of 16 percent because the new value is greater than the old value.
