Answer:
n = 17
[tex]\frac{n}{85}= \frac{34}{170}[/tex]
Step-by-step explanation:
[tex]\frac{n}{85}= \frac{34}{170}[/tex]
n · 170 = 34 · 85
170y = 2890
170y ÷ 170 = 2890 ÷ 170
y = 17

The number of marbles of different colors stored in a hat is listed below:
4 red marbles
10 green marbles
7 blue marbles
Without looking in the hat, Dan takes out a marble at random. He replaces the marble and then takes out another marble from the hat. What is the probability that Dan takes out a blue marble in both draws?

Mary noticed 5 ants in her pantry on Monday. On Tuesday she counted 15 ants in the pantry. On Wednesday she counted 45 ants in the pantry. Part A Determine an exponential function model to represent the number of ants in the pantry in terms of the number of elapsed days. Explain how you arrived at your model. Part B Using your exponential model predict how many ants would be in the pantry by Friday if the trend continues. Explain if your response is reasonable. Part C Does the problem situation represent exponential growth or decay? Justify your reasoning.

Answer:
b. the slopes of both functions are positive
Step-by-step explanation:
hope this helps :)
Answer:
C. The slope of function A is positive and the slope of function B is negative.
Step-by-step explanation:
For this problem, you need to determine the slope of each function.
For function A:
You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.
So the slope for function A is 1/4.
For function B:
You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)
Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].
Therefore, the slope of function A is positive and the slope of function B is negative.

The developer of the test claims that the population standard deviation of 15. Do these data provide sufficient evidence to significance? Use =0.05α=0.05 . Test by using a confidence interval. Show step1-step3.
Answer:
Yes, the data provides sufficient evidence at 0.05 level of significance
Step-by-step explanation:
n = 25
s = 8
σ = 15
χ² = (n - 1)s² / σ²
χ² = (25 - 1)*8² / 15²
χ² = (24 * 64) / 225
χ² = 6.827

Justin likes to get 7 hours of sleep. He woke up after sleeping for 5 1/3 hour. How many more hours does he need to get the amount of sleep he likes?
Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes
1/3 hours = 60/3 = 20 minutes
Hours Minutes
7 00 when we borrow 1 hour we borrow 60 minutes
5 20
1 40
He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours

Step-by-step explanation:
the slope looks like it's 4/1 when simplified it's 4. (integer)
Answer:
The slope is the integer 4
Step-by-step explanation:
take the points (-2, -9) (-1, -5) and put them in the formula y2 - y1 over x2 - x1 and you get m = 4
Simplify.
Multiply and remove all perfect squares from inside the square roots. Assume b is positive.
Answer:
216*b^2
Step-by-step explanation:
first, remember that:
a*√b = √(a^2*b)
√a*√b = √(a*b)
[tex]b^n*b^m = b^{n + m}[/tex]
[tex](b^n)^m = b^{n*m}[/tex]
Now, our expression is:
[tex]2*\sqrt{8*b^3} *9*\sqrt{18*b} = (2*9)*\sqrt{8*b^3}*\sqrt{18*b}[/tex]
Where in the right I rewrite the expression so it is easier to work.
Now we can use the second property of the above ones, to have:
[tex]18*\sqrt{8*b^3*18*b} = 18*\sqrt{(8*18)*b^{3 + 1}} = 18*\sqrt{144*b^4}[/tex]
And we know that:
[tex]\sqrt{x} = x^{1/2}[/tex]
Then:
[tex]18*\sqrt{144*b^4} = 18*(144*b^4)^{1/2} = 18*\sqrt{144}*(b^4)^{1/2}[/tex]
and 12*12 = 144, then:
[tex]18*\sqrt{144}*b^{4*1/2} = 18*12*b^2 = 216*b^2[/tex]

It costs $45 for 3 xylophones and 3 yo-yo's. If you purchased 5 xylophones and
6 yo-yo's, it would cost $80. Set up a system of equations and solve for the
cost of a single xylophone and a single yo-yo.
Step-by-step explanation:
xylophone : x
yo-yo : y
3x + 3y = 45 —(1)
5x + 6y = 80 —(2)
(1)*2 : 6x + 6y = 90 —(3)
(3)-(2):
6x + 6y = 90
-(5x + 6y) = 80
x =10 — (4)
Sub (4) into (1)
3(10) + 3y = 45
30 + 3y = 45
3y = 45-30
y = 15/3
y = 5

A 2-yard piece of cotton cloth costs $1.32. What is the price per foot?
Answer:
$0.22 per foot
Step-by-step explanation:
So for context, 1 yard is 3 feet. So 2 yards is 6 feet. With this, by dividing $1.32 by 6, you can get the price per foot:
1.32 / 6 ---> $0.22 per foot.

Do you guys know how to solve with equation?
Answer:
{-8, 3/4}
Step-by-step explanation:
One by one, set the factors equal to zero and solve for v:
8 + v = 0 yields v = -8, and
4v - 3 = 0 yields 4v = 3 and v = 3/4
