What is the range of possible sizes for side x?
Answer:
x = 3.96
Step-by-step explanation:
To find the missing side length you'll need the formula a^2 + b^2 = c^2
a and b would be the shorter ends, 2.8 and 2.8
c would be the longer end that's opposite the right angle.
so substitute values
2.8^2 + 2.8^2 = c^2
7.84 + 7.84 = c^2
15.68 = c^2
√15.68 = √c^2
3.959797 = c
c = 3.96
side c would be side x so x is 3.96

The area of a rectangle is 130 mm². The length is 3 mm greater than its width. Let x represent the width of the rectangle.
Which equation can be used to solve for x?
O A. 3x = 130
O B. x2 + 3 = 130
C. x(x + 3) = 130
D. (x+3)2 = 130
Answer:
L = 3 + x
W = x
A = L x W
130 = 3 +( x × x)
B. X2 + 3 = 130
The equation that can be used to solve for x is;
x(x + 3) = 130
Area of a RectangleWe are told that area of a rectangle is;
A = 130 mm².
We are told that length is 3 mm greater than its width.
Now, if the width is x, then
Length = x + 3
Formula for area of a rectangle is;
A = length * width
Thus;
(x + 3)x = 130
x² + 3x = 130

A tube-feeding formula is administered to a patient via Gastrostomy at 75
ml/hr. The formula contains 6.5% protein. How much protein will the patient
receive in the entire day, if the feeding must be held (stopped) for 2 hours
before and 2 hours after the administration of Dilantin twice a day?
39
Answer:
97.5ml protein
Step-by-step explanation:
20hr * 75ml/hr = 1500ml
1500ml * .065 = 97.5ml protein
The patient will receive 78 ml protein in the entire day.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Tube feeding formula = 75 ml/hr
Protein content = 6.5% of 75 ml/hr = 0.065*75 ml/hr
⇒ Protein content = 4.875 ml/hr
Now since, the feeding must be held (stopped) for 2 hours before and 2 hours after the administration of Dilantin twice a day
So, Stoppage total hours = 2(2 + 2) = 2*4
⇒ Stoppage total hours = 8
Thus, total hours in a day when formula is feed = 24 - 8 = 16 hours
Thus Protein received by patient = 16hr * 4.875 ml/hr
⇒ Protein received by patient = 78 ml
Thus, the patient will receive 78 ml protein in the entire day.

Answer:
B(3/4*1/2)
Step-by-step explanation:
So lets see, we have:
3/4 divded by 2
Any whole number, such as 2, will have a denominator like this:
2/1
So we can rewrite this as:
3/4 divided by 2/1
Now, we can actually rewrite this division as multipication. To do this, you must flip the dividing fraction, which was 2/1.
So now it is 1.2:
3/4*1/2
Looking at the anwers, this should be the seocnd one down.
Hope this helps!

A sample of 1600 computer chips revealed that 43% of the chips fail in the first 1000 hours of their use. The company's promotional literature states that 44% of the chips fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that fail is below the stated percentage. Is there enough evidence at the 0.05 level to support the manager's claim
Answer:
The p-value of the test is 0.209 > 0.05, which means that there is not enough evidence at the 0.05 level to support the manager's claim.
Step-by-step explanation:
The company's promotional literature states that 44% of the chips fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that fail is below the stated percentage.
At the null hypothesis, we test if the proportion is of 44%, the stated value. So
[tex]H_0: p = 0.44[/tex]
At the alternate hypothesis, we test if the proportion is below the stated value, that is, it is less than 0.44. So
[tex]H_1: p < 0.44[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.44 is tested at the null hypothesis:
This means that [tex]\mu = 0.44, \sigma = \sqrt{0.44*0.56}[/tex]
A sample of 1600 computer chips revealed that 43% of the chips fail in the first 1000 hours of their use.
This means that [tex]n = 1600, X = 0.43[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.43 - 0.44}{\frac{\sqrt{0.44*0.56}}{\sqrt{1600}}}[/tex]
[tex]z = -0.81[/tex]
P-value of the test:
The p-value of the test is the probability of finding a sample proportion below 0.43, which is the p-value of z = -0.81.
Looking at the z-table, z = -0.81 has a p-value of 0.209.
The p-value of the test is 0.209 > 0.05, which means that there is not enough evidence at the 0.05 level to support the manager's claim.

Aaron participates in a walkathon for charity. He has a sponsor who has pledged a base donation of $2 for the first mile he walks and then a certain dollar amount for each additional mile he walks. Based on this pledge, if Aaron walks 8 miles, the sponsor will donate a total of $23 to the charity.
Write a formula that can be used to determine the amount of money this sponsor donates when Aaron walks n miles.
Explain how you determined your formula.
Answer:
2 + 3x(N-1) = Amount of money donated
Step-by-step explanation:
Since Aaron participates in a walkathon for charity, and he has a sponsor who has pledged a base donation of $ 2 for the first mile he walks and then a certain dollar amount for each additional mile he walks, and based on this pledge, if Aaron walks 8 miles, the sponsor will donate a total of $ 23 to the charity, to determine a formula that can be used to determine the amount of money this sponsor donates when Aaron walks N miles the following equation should be raised:
2 = fixed amount in the first mile
2 + ((23 - 2) / (8-1)) x (N-1) = Amount of money donated
2 + (21/7) x N = Amount of money donated
2 + 3x (N-1) = Amount of money donated
Thus, if N is 8, as in the example, the quantity is determined as follows:
2 + 3x (8-1) = X
2 + 3x7 = X
2 + 21 = X
23 = X
