Answer:
10.5 pounds
Step-by-step explanation:
150 x 0.07 = 10.5 pounds
The weight of blood in patient is 8.5 lbs
What are mathematics operations?
• A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
It is given that :
weight of patient is = 150 lbs
and, also Blood accounts for 7% of the total body weight
Now, to find the weight of blood in patient we simply multiply 7% with 150 lbs :
weight of blood = 7% x 150 lbs
weight of blood = 8.5 lbs
Therefore, the weight of blood in patient is 8.5 lbs

Choose 1 answer:
(Choice A)
Perimeter
(Choice B)
Length
(Choice C)
Area
Answer:
(Choice A) Perimeter
Step-by-step explanation:
It can't be the length, because it states in the question that the length is 7 m
and it can't be the area because lw = 7(8) = 56 is the area.
There are 12 cans of soup in a carton. Each can has a
diameter of 8 cm and a height of 9 cm. How much paper, to
the nearest square centimeter, is needed to make labels that
wrap around each of the 12 cans? (Assume there is no
overlap.)
Answer:
The required amount of paper is 2715.23 [tex]cm^{2}[/tex].
Step-by-step explanation:
The cans of soup has a shape of a cylinder, so that;
The surface area around a cylinder = 2[tex]\pi[/tex]rh
Where: r is the radius of the can, and h is its height.
From the given question, diameter = 8 cm, then;
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{8}{2}[/tex]
r = 4 cm
Surface area around one of the cans = 2 x [tex]\frac{22}{7}[/tex] x 4 x 9
= 226.2857
Surface area around one of the cans = 226.28 [tex]cm^{2}[/tex]
So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:
12 x 226.2857 = 2715.4284
The required amount of paper is 2715.23 [tex]cm^{2}[/tex].

Mr. Bruce has some clay with a mass of 24 kilograms. If he puts the same amount of clay into 6 bags, how many grams of clay are in each bag? I NEED THE EXPLANATION
Answer:
4000grams in each bag
Step-by-step explanation:
Assume he put x amount of clay into each bag, he then put 6x into 6 bags.(since the question didn’t mention, I assume he put every clay he has into the bags)
6x=24kg
x=4kg
Since the question is asking for grams not kilograms:
4kg=4000g

- Scores on an exam are normally distributed woth a population standard deviation of 5.6. A random sample of 40 scores on the exam has a mean of 32 estimate the population mean with - A) 80% confidence - B) 90% - C) 98%
Answer: i think i got b or c onr of them are correct :)
Step-by-step explanation:
The estimated population mean with
80% confidence = [30.856, 33.135]
90% confidence = [30.543, 33.456]
98% confidence = [29.94, 34.06]
What is confidence interval?For a population with unknown mean and known standard deviation , a confidence interval for the population mean, based on a simple random sample of size n, is [tex]\bar x +_{-}z^{*}\frac{\sigma}{\sqrt{n} }[/tex] , where z* is the upper (1-C)/2 critical value for the standard normal distribution.
Population standard deviation = 5.6
Sample mean = 32
Sample size = 40
Given confidence level = 80%
[tex]z^{*}[/tex] at 80% confidence level = 1.28
Upper confidence interval = 33.135
Lower confidence interval = 30.865
Population mean lies between [30.856, 33.135] at 80% confidence level.
Given confidence level = 90%
[tex]z^{*}[/tex] at 90% confidence level = 1.65
Upper confidence interval =33.456
Lower confidence interval = 30.543
Population mean lies between [30.543, 33.456] at 90% confidence level.
Given confidence level = 98%
[tex]z^{*}[/tex] at 98% confidence level = 1.65
Upper confidence interval = 34.06
Lower confidence interval = 29.94
Population mean lies between [29.94, 34.06] at 98% confidence level.

Using solver program, the expression 2x^4-6x^2+10x-7 has:
two real roots at x≈-2.3888 and x≈1.1424
and
two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i

Answer:
x = 5√2
y = 15
Step-by-step explanation:
By applying sine rule in the given right triangle,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{y}{10\sqrt{2}}[/tex]
y = [tex]\frac{\sqrt{3} \times 10\sqrt{2} }{2}[/tex]
y = 15
Similarly, by applying cosine rule in the given triangle,
cos(60°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{x}{10\sqrt{2}}[/tex]
x = 5√2

The dot plots show the number of hours a lightbulb lasts from two different brands. Brand A. Number of hours per lightbulb 1000 4200 1400 1500 1800 2000 Brand B Number of hours per lightbulb .. 1200 1400 1600 1800 2000 Which of the following statements is correct? A. There were more lightbulbs in the dot plot for brand B than in the dot plot for brand A. B. The mean for brand A is the same as the mean for brand B. C. The mean for brand A is higher than the mean for brand B. D. The mean for brand B is higher than the mean for brand A.
Answer:
Step-by-step explanation:
The mean for brand A is higher than the mean for brand B
The mean for brand A is higher than the mean for brand B because the mean for A is 1983.33 and the mean for B is 1600 statement (C) is correct.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We have:
For brand A:
The number of hours per lightbulb:
1000, 4200, 1400, 1500, 1800, 2000
Mean for brand A:
[tex]\rm Mean(A) = \frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ in \ the\ set}[/tex]
[tex]\rm Mean(A)= \frac{1000+4200+1400+1500+1800+ 2000}{6}[/tex]
[tex]\rm Mean(A)= \frac{11900}{6}\\\\\rm Mean(A) = 1983.33[/tex]
For Brand B:
The number of hours per lightbulb:
1200, 1400, 1600, 1800, 2000
Mean for brand B:
[tex]\rm Mean(B) = \frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ in \ the\ set}[/tex]
[tex]\rm Mean(B)= \frac{1200 +1400 +1600 +1800 +2000}{6}[/tex]
[tex]\rm Mean(B)= \frac{8000}{5}\\\\\rm Mean(B) = 1600[/tex]
We can see that:
Mean(A) > Mean(B)
Thus, the mean for brand A is higher than the mean for brand B because the mean for A is 1983.33 and the mean for B is 1600 statement (C) is correct.

State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below. A. Reject H0 because the P-value is less than or equal to α. B. Fail to reject H0 because the P-value is less than or equal to α. C. Fail to reject H0 because the P-value is greater than α. D. Reject H0 because the P-value is greater than α.
Answer:
A. Reject H0 because the P-value is less than or equal to α.
Step-by-step explanation:
Decision:
If the pvalue of the test is less than the significance level, we reject the null hypothesis H0.
Otherwise, we fail to reject the null hypothesis H0.
In this question:
Significance level: 0.01
P-value: 0.0087
0.0087 < 0.01, so we reject H0.
