Answer:
There are 15 carbs in one glass of milk and 13 carbs in one snack bar.
Step-by-step explanation:
Let m be the number of carbohydrates in one glass of milk and
Let s be the number of carbohydrates in one snack bar
Then according to given information
The system of equations will be:
[tex]4m+2s = 86\\2m+3s = 69[/tex]
Multiplying equation 2 by 2 and subtracting from equation 1
[tex]2(2m+3s) = 69*2\\4m+6s = 138[/tex]
Subtracting from equation 1
[tex]4m+2s-(4m+6s) = 86-138\\4m+2s-4m-6s = -52\\-4s = -52\\\frac{-4s}{-4} = \frac{-52}{-4}\\s = 13[/tex]
Putting s=13 in equation 1
[tex]4m+2(13) =86\\4m+26 = 86\\4m = 86-26\\4m = 60\\\frac{4m}{4} = \frac{60}{4}\\m = 15[/tex]
Hence,
There are 15 carbs in one glass of milk and 13 carbs in one snack bar.

a²+b²=c²a²+12²=15²a²+144=225225-144=81√81=9Suppose a binomial trial has a probability of success of 0.3, and 500 trials are performed. What is the standard deviation of the possible outcomes? Round
your answer to two decimal places.
O A. 10.25
OB. 8.94
O c. 6.71
D. 10.95
The standard deviation of the possible outcomes is to be considered as the 10.25.
Calculation of the standard deviation:Since there is a binomial trial has a probability of success of 0.3, and 500 trials are performed.
So here
q = 1 - P
= 1 - 0.3
=0.7
Now the standard devation be like
[tex]= \sqrt{500\times 0.3 \times 0.7}[/tex]
= 10.25
hence, The standard deviation of the possible outcomes is to be considered as the 10.25.

You bought 5 chocolate bars and 8 blow pops for $23.25. Your sister bought 2 chocolate bars and 13 blow pops for $21.55. How much did each chocolate bar cost?
Answer:
$2.65Step-by-step explanation:
Let chocolate bar cost = c and blow pops cost = b
As per given we have equations below:
5c + 8b = 23.25 2c + 13b = 21.5513 times the first equation minus 8 times the second to eliminate b and find c:
13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55) 65c - 16c = 129.85 49c = 129.85 c = 129.85/49 c = 2.65Each chocolate bar costs $2.65

The American College Testing Corporation has a test called the ACT that is used for admissions to college. The American College Testing Corporation reports that students who attend 2-year colleges in the Midwest United States have an average ACT score of 21.5, with a standard deviation of 3.17. The president of the Minneapolis Community College wonders if students who attend her college have a ACT scores that are significantly different from the ACT scores reported by the American College Teaching Corporation. The president would perform a ___________ test, and use a z-critical value of _____.
Answer:
Two tailed test
+/-1.96
Step-by-step explanation:
Following this claim, the president would have to perform a two tailed test. Since he wants to know if the Act scores of students in her school are significantly different from what is reported by the ACT corporation.
At a confidence level that is 95%, the level of significance is = 0.05. then the z critical value to be used would be +/- 1.96

Solve the following system of equations graphically on the set of axes below.
Y=1/3x+6 y=-5/3x-6
Answer:
I can not solve it in the system of the image, but i will give you the graph so you can copy it, or at least see how it is done.
First, we have the lines:
y = (1/3)*x + 6
y = (-5/3)*x - 6
To graph these lines, you must find two points for the lines and then draw a line that connects the points.
To do it, you can evaluate each line in two different values of x, for example for the first line we can have:
y(0) = (1/3)*0 + 6 = 6 (then we have the point (0, 6))
y(3) = (1/3)*3 + 6 = 7 (then we have the point (3, 7))
And for the second line, we will have:
y(0) = (-5/3)*0 - 6 = -6 (then we have the point (0, -6))
y(3) = -(5/3)*3 - 6 = -11 (then we have the point (-3, -11))
Now with those points we can graph the lines, and the solution of the system of equation will be the point where the two lines intersect.
The graphs of the lines are shown below:
Where the grey line is the first one, and the green is the second.
In the graph, you can see that the lines intersect in the point (-6, 4)
Then the solution for the system is x = -6, and y = 4.
Graph the line that passes through the two lines (1,5/2), (-1/2,-1/4)
Answer:
Image below
Step-by-step explanation:
Graph of a Line Given Two Points
We are given the points (1,5/2), (-1/2,-1/4).
A straight line is entirely defined by two points. We have to plot them and join them with a straight line ending in arrows.
The point (1,5/2) is converted to decimal as (1,2.5)
The point (-1/2,-1/4) is also converted to decimal: (-0.5,-0.25)
This helps to define the divisions of each axis and properly draw the line.

Answer:
150 and -150
Step-by-step explanation:
For question number 2...
You started off with an energy level of 250 and something was added to make it 400.
To figure out what this "something" was, you simply subtract the numbers.
400 - 250 = 150
For question number 3...
You start off with 325 and end with 175. Here, the outcome is smaller or less than what you started with. So, you know that you took away a certain amount of energy. To figure that out, you again subtract.
325 - 175 = 150
To make the equation make sense, you would subtract 150.
So the answer would -150.

Answer:
9 cm.
Step-by-step explanation:
First, let's form an equation. We'll represent the final depth of snow on Cherry Street with the variable d. We'll represent the hours with the variable h.
10 - 1/3h = d
Now, you already know what h equals so you can replace h with 3 for 3 hours.
10 - 1/3(3) = d
1/3 * 3 = 1.
10 - 1 = d
10 - 1 = 9
Now, we know what d equals.
10 - 1/3(3) = 9.
Do NOT forget the unit of measurement in your final answer, cm. In the photo, it looks as though it has already been provided.
The final answer is 9 cm.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of grams and a standard deviation of grams while babies born after a gestation period of 40 weeks have a mean weight of grams and a standard deviation of grams. If a -week gestation period baby weighs grams and a -week gestation period baby weighs grams, find the corresponding z-scores. Which baby weighs relative to the gestation period?
Complete question :
Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 410 grams. If a 32 -week gestation period baby weighs 3300 grams and a 40 -week gestation period baby weighs 3600 grams, find the correspondingz-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more?
Answer:
32 - 35 weeks = 0.56
40 weeks : 1.22
40 weeks babies weigh more
Step-by-step explanation:
Given that :
32 - 35 weeks babies :
Mean (m) = 2800
Standard deviation (s) = 900
Weight (x) = 3300
40 weeks babies :
Mean (m) = 3100
Standard deviation (s) = 410
Weight (x) = 3600
Obtain the standardized score for both categories :
Zscore = (x - m) / s
32 - 35 weeks :
Zscore = (3300 - 2800) / 900
Zscore = 0.555555 = 0.56
40 weeks :
Zscore = (3600 - 3100) / 410
Zscore = 1.2195121 = 1.22
Zscore for 40 weeks is higher than 32-35 weeks.
Hence, 40 weeks babies weigh more.
