A sum of $104 is divided among three friends Adam, Charlie and Max in the ratio
3:4:6. How much more money does Max have than Adam?
Answers
Answer:
$ 24
Step-by-step explanation:
Ratio = 3 : 4 : 6
Amount with Adam = 3x
Amount with Charlie = 4x
Amount with Max = 6x
Total amount = $104
3x + 4 x + 6x = 104
13x = 104
x = 104/13
x = 8
Amount with Max = 6x = 6*8 = $ 48
Amount with Adam = 3x = 3 *8 = $ 24
Amount that is more with Max than Adam = 48 - 24 = $ 24
A sum of $104 is divided among three friends Adam, Charlie and Max in the ratio 3 : 4 : 6. How much more money does Max have than Adam ?
Solution:-Ratio = 3 : 4 : 6 (Given)
[tex] \bullet [/tex] Let the sum of Adam be 3x
[tex] \bullet [/tex] Let the sum of Charlie be 4x
[tex] \bullet [/tex] Let the sum of Max be 6x
[tex] \therefore [/tex] Total sum = $104 (Given)
So,
ATQ ,
3x + 4x + 6x = 104
13x = 104
x = [tex] \bf \frac{104}{13} [/tex]
x = 8Now, total sum of Adam = 3x = 3 × 8 = $24
Total sum of Max = 6x = 6 × 8 = $48
Required money Max have more than Adam = (48 - 24) = $24
$24 money does Max have more than Adam. [Answer]How many odd numbers are in 10 to 50?

a shopkeeper bought 2 watches for rs 400. he sold them to gain 5% one and loss 5% on other. calculate his final gain or loss percent. if the selling price of both watches is same.
Answers
He bought 2 watches for $400
400/2=200
Each watch was $200
He gained 5% on one watch
200•1.05=210
He lost 5% on the other
200•0.95=190
210+190=400
Therefore he neither made nor lost any money

A physiologist believes he has discovered a new steroid hormone that can control the blood glucose in mammals. In an experiment he injects laboratory rats with a small amount of this steroid hormone and, after a suitable waiting period measures the blood glucose level of the rats. In his twelve experimental rats he obtains the following levels of blood glucose {35,36,37,33,34,35,33,35,37,36,34,35}. From previous studies of thousands of normal, un-manipulated rats he knows that the mean (mu) blood glucose level in this species of rat (his laboratory population) is 31 and that the standard deviation is 4.12. Evaluate the hypothesis that this new steroid hormone affects blood glucose levels. Use an alpha-level of 0.01 for this analysis.
Required:
a. What is the appropriate test?
b. State the null hypothesis.
c. State the alternative hypothesis.
d. Find the critical value.
e. Calculate the obtained statistic.
Answers
Answer:
1.) One sample t test
2.) New steroid does not decrease blood glucose level in rats ; H0 : μ = 31
3.) New steroid does blood glucose level in rats ; H1 : μ ≠ 31
4.) 2.718
5.) 3.36
Step-by-step explanation:
We only have one sample; hence, we use an independent sample t test.
Given the sample data :
X : 35,36,37,33,34,35,33,35,37,36,34,35
Using calculator;
Sample mean, Xbar = 35
Null hypothesis ;supports that the mean glucose level of species equals ; H0 : μ = 31
The alternative hypothesis ; H1 negates the null hypothesis and aligns with the sample mean ; 35 > 31 ;
H1 : μ > 31
The critical value can be obtained from the T-distribution table ;
α = 0.01 ; degree of freedom, df = n - 1 = 12 - 1 = 11
Tcritical value = 2.718
Tstatistic : (xbar - μ) ÷ (s/√n)
Tstatistic = (35 - 31) ÷ (4.12/√12)
Tstatistic = 3.36
Tstatistic is more extreme Than the critical value

Ms. Phillips ordered 56 pizzas for a school fundraiser. Of the pizzas ordered, 2/7 of them were pepperoni, 19 were cheese, and the rest were veggie pizzas. What fraction of the pizzas was veggie?
Answers
Answer:
5 / 28
Explanation:
Total number of Pizza's ordered = 56
Pepperoni = 27
Cheese = 19
The remainder were Veggie ;
Fraction of pizza that were. Veggie
Number of pizza's that were Veggie :
56 - (27 + 19)
56 - 46
= 10
Fraction of Veggie pizza :
Number of Veggie pizza / total number of Pizza's
10 / 56
= 5 / 28

Let the angle of elevation be \thetaθ
\begin{gathered} \therefore \tan \: \theta = \frac{height \: of \: mast}{height \: of \: shadow} \\ \\ \therefore \tan \: \theta = \frac{44}{14} \\ \\ \therefore \tan \: \theta = 3.14285714 \\ \\ \therefore \: \theta = {\tan}^{ - 1} (3.14285714) \\ \therefore \: \theta = 72.349875765 \degree \\ \\ \huge \red{ \boxed{\therefore \:\theta = 72.35 \degree}}\end{gathered}
∴tanθ=

Really stumped on these 2 problems anybody know anything? "Find the circumference of each circle. Round to the nearest tenth. Use 3.14 or 22/7 for π"
Answers
Answer:
1. 15.7 in
2. 153.9 cm
Step-by-step explanation:
The circumference of a circle is found by the formula:
C = 2 * pi * r, where r represents the radius.
For the first circle, we substitute in 3.14 for pi and the given radius:
C = 2 * 3.14 * 2.5
C = 15.7 in
However, for the second circle, the diameter is given instead of the radius.
As the radius is just half of the diameter, we can find that it is 24.5 cm.
Substituting the values in, we get:
C = 2 * 3.14 * 24.5
C = 153.86 cm
Rounding to the nearest tenth gives us:
153.9 cm

Multiple regression is sometimes used in litigation. In the case of Cargill, Inc. v. Hardin, the prosecution charged that the cash price of wheat was manipulated in violation of the Commodity Exchange Act. In a statistical study conducted for this case, a multiple regression model was developed to predict the price of wheat using three supply-and-demand explanatory variables.Data for 14 years were used to construct the regression equation, and a prediction for the suspect period was computed from this equation. The value of R2was 0.989.
(a) The fitted model gave the predicted value $2.136 with standard error $0.013. Express the prediction as an interval. (The degrees of freedom were large for this analysis, so use 100 as the df to determine t*.)
(b) The actual price for the period in question was $2.13. The judge decided that the analysis provided evidence that the price was not artificially depressed, and the opinion was sustained by the court of appeals. Write a short summary of the results of the analysis that relate to the decision and explain why you agree or disagree with it.
Answers
Answer:
($2.123 ; $2.149)
Step-by-step explanation:
The prediction interval is expressed as :
Predicted value ± standard Error
Predicted value = $2.136
Standard Error = $0.013
Prediction interval :
Lower boundary = $2.136 - $0.013 = $2.123
Upper boundary = $2.136 + $0.013 = $2.149
($2.123 ; $2.149)
B.) The prediction interval provides a range for which the predicted value or price should fall Given a certain degree of probability. If the true value falls within this interval, then, our prediction would be deemed to have occurred not by chance.
Since the actual price within the predicted price interval, then I agree with the judge's Decison that the price was not artificially depressed.
