A Christian relief agency is sending two types of medical supply boxes overseas. The original plan is to send 3 boxes of medicines and 7 boxes of non-medicine supplies worth a total value of $9,000. Shortly before the supplies are shipped, the agency receiving the supplies communicates that they only need 2 boxes of medicines. If a box of non-medicine supplies is worth $300, how many boxes of non-medicine supplies can be sent if only 2 boxes of medicine are included in the shipment
Answers
The number of non-medicine that can be sent is approximately 14 boxes.
From the given statement we can form the following equation:
let the worth of a boxes of medicine = x
3x + 7(300) = 9,000
solve for x:
3x + 7(300) = 9,000
3x + 2,100 = 9,000
3x = 9,000 - 2,100
3x = 6,900
[tex]x = \frac{6,900}{3} = 2,300[/tex]
A box of medicine worth $2,300
If only 2 boxes of medicine will be sent, then the number of boxes of non-medicine is calculated as;
let the worth of all the boxes of non-medicine = y
2(2,300) + y = 9,000
4600 + y = 9,000
y = 9,000 - 4600
y = 4,400
Now we solve for the number of boxes of non-medicine as follows:
n(300) = 4,400
[tex]n= \frac{4400}{300} = 14.67 \approx 14 \ boxes \ of \ non-medicine \ can \ be \ sent[/tex]
Thus, the number of non-medicine that can be sent is approximately 14 boxes.

What is the value of the expression -11 + 24 + (-32)
Answers
Answer:
-19
Step-by-step explanation:
Just used the calculator, hope this helps
Answer:
-19
Step-by-step explanation:
You can split the equation into two steps:
1. - 11 + 24. You can also flip around the terms and get 24 - 11. 24 - 11 = 13 so - 11 + 24 = 13.
Next -
2. 13 + (-32). When you are adding a negative number, it is the same as subtracting the positive of that number, so we can turn the equation into 13 - 32. 13 - 32 = -19

Let's suppose we conduct a hypothesis test about the mean value of something, and determine that we should reject the null hypothesis. What does that mean?
a. Our hypothesized mean has been proven incorrect
b. The difference between our sample mean and our hypothesized mean was most likely due to random chance.
c. The difference between our sample mean and our hypothesized mean was statistically significant.
d. The difference between our sample mean and our hypothesized mean was not statistically significant.
Answers
Answer: Choice C.
The difference between our sample mean and our hypothesized mean was statistically significant.
=========================================================
Explanation:
The null hypothesis is always set up in a way to state the following: "The mean mu is equal to some value"
The mu is a greek letter often used as the population mean symbol. The actual symbol itself looks like this [tex]\mu[/tex]
When we reject the null, we reject the idea that the mu is whatever stated value we said in the null. So we must go with the alternative hypothesis.
The sample mean we computed (xbar) is different enough from the mu value that we're able to make such a rejection. We consider this statistically significant, which is another way of saying that such a difference is not simply due to random chance.

Answer:
83 m
Step-by-step explanation:
The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...
8.26(10 m) = 82.6 m ≈ 83 m
_____
The distance formula will tell you the distances are ...
AC = √(3² +1²) = √10
BD = √(5² +1²) = √26
The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.
Find the value of x and
y if x-y=3 and 2x+3y=4
Answers
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5
2x+3y=4
Using elimination we can multiply the top equation by -2 to Eliminate the x values. Doing this gives us
-2(x-y)= -2(3)
Simplifying we have
-2x+2y=-6
And then adding the second equation, we can have a system of two equations where the x eliminates
-2x+2y=-6
+2x+3y=+4
Adding we get that
5y=-2
Dividing by 5 on both sides gives us y=-2/5
We can substitute this y term in for the first equation. Doing so we have
x-(-2/5)=3
using the a-(-b)=a+b rule we get
x+2/5=3
Thus x=3- 2/5
So using a calculator we can say that x=13/5.
Thus your answers are x=13/5 and y=-2/5
