The length of a rectangle is twice its width.
If the perimeter of the rectangle is 30 cm, find its length and width.
Answer:
width - 5cm
length - 10cm
Step-by-step explanation:
Let's define the variable w as the width of the rectangle. The length of the rectangle would be 2w as given by the problem. A form of the perimeter of a rectangle formula is:
P = 2(l + w)
Where P is the perimeter, l is the length, and w is the width. We substitute our length, width, and perimeter to get:
30 = 2(2w + w)
You can simplify to get:
30 = 2(3w)
and divide by 6 on both sides to isolate w:
w = 5cm - the width is 5 cm
The length is twice the width, and 2 x 5 is 10, so 10cm is the length.

1. You borrow $500 from a bank with a 5% annual interest and
the maturity date is in 3 years
a. How much would you pay in interest at the end of the
loan if you pay simple interest
b. How much would you pay in interest at the end of the
loan if you pay in compound interest
Answer:
Step-by-step explanation:
Discussing interest starts with the principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.

The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.30 liters. A health campaign promotes the consumption of at least 2.0 liters per day. A sample of 10 adults after the campaign shows the following consumption in liters:
1.361.351.331.661.581.321.381.421.901.54
At the 0.050 significance level, can we conclude that water consumption has increased? Calculate and interpret the p-value.
A.) State the null hypothesis and the alternate hypothesis.
H0: μ ≤ _____
H1: μ >_____
B.) State the decision rule for 0.050 significance level. (round to 3 decimal places)
C.) Compute the value of the test statistic. (round to 3 decimal places)
D.) At the 0.050 level, can we conclude that water consumption has increased?
E.) Estimate the p-value.
Answer:
H0: μ ≤ 1.30
H1: μ > 1.30
|Test statistic | > 1.833 ; Reject H0
Test statistic = 3.11
Yes
Pvalue = 0.006
Step-by-step explanation:
H0: μ ≤ 1.30
H1: μ > 1.30
Samples, X ; 1.36,1.35,1.33, 1.66, 1.58, 1.32, 1.38, 1.42, 1.90, 1.54
Xbar = 14.84 / 10 = 1.484
Standard deviation, s = 0.187 (calculator)
Decison rule :
|Test statistic | > TCritical ; reject H0
df = n - 1 = 10 - 1 = 9
Tcritical(0.05; 9) = 1.833
|Test statistic | > 1.833 ; Reject H0
Test statistic :
(xbar - μ) ÷ (s/√(n))
(1.484 - 1.30) ÷ (0.187/√(10))
0.184 / 0.0591345
Test statistic = 3.11
Since ;
|Test statistic | > TCritical ; We reject H0 and conclude that water consumption has increased
Pvalue estimate using the Pvalue calculator :
Pvalue = 0.006
What is the solution set to the equation
15 – 4x = x2 - 6x ? Show your work algebraically.
Answer:
The solution of given expression = 5 , -3
Step-by-step explanation:
Given expression;
15 - 4x = x² - 6x
Find:
The solution of given expression
Computation:
15 - 4x = x² - 6x
x² - 6x + 4x - 15 = 0
x² - 2x - 15 = 0
x² - (5 - 3)x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) + 3(x - 5) = 0
(x - 5)(x + 3) = 0
So,
x - 5 = 0 and x + 3 = 0
x = 5 and x = -3
The solution of given expression = 5 , -3

Me jackson buys 4 kilograms of peanuts at the sale how many grams of peanuts does he get in all
Keep in mind : buy 2 kg peanuts get 300 g free
Answer:
4600 grams of peanuts
Step-by-step explanation:
For 2 kg of peanuts the customer will get 300 g free.
So if 4 kg of peanuts the customer will get 600 g free.
1kg = 1000g
If 4kg, thus it is 4000g
All mass of peanut the customer gets is 4000g + 600g = 4600g of peanuts.
which pair of words describes this system of equations 3y=9x-6 2y+6x=4
Answer:
Consistent and dependent
Step-by-step explanation:
Given
[tex]3y = 9x - 6[/tex]
[tex]2y + 6x = 4[/tex]
Required
The words that describe the equations
Make y the subject in (2)
[tex]2y + 6x = 4[/tex]
Collect like terms
[tex]2y = 4 - 6x[/tex]
Divide through by 2
[tex]y = 2 - 3x[/tex]
Substitute: [tex]y = 2 - 3x[/tex] in (1)
[tex]3y = 9x - 6[/tex]
[tex]3(2 - 3x) = 9x - 6[/tex]
[tex]6 - 9x = 9x - 6[/tex]
Collect like terms
[tex]9x+9x = 6+6[/tex]
[tex]18x = 12[/tex]
Solve for x
[tex]x = \frac{12}{18}[/tex]
Simplify
[tex]x = \frac{2}{3}[/tex]
Substitute [tex]x = \frac{2}{3}[/tex] in [tex]y = 2 - 3x[/tex]
[tex]y = 2 - 3*\frac{2}{3}[/tex]
[tex]y = 2 - 2[/tex]
[tex]y =0[/tex]
So, we have:
[tex]x = \frac{2}{3}[/tex] and [tex]y =0[/tex]
The system is consistent because it has at least 1 solution
The system is dependent because it has more than 1 solution
A large national bank charges local companies for using their services. A bank official reported the results of a regression analysis designed to predict the bank's charges (Y)—measured in dollars per month—for services rendered to local companies. One independent variable used to predict the service charge to a company is the company's sales revenue (X)—measured in millions of dollars. Data for 21 companies who use the bank's services were used to fit the model:
E(Y) = ß0 + ß1X
The results of the simple linear regression are provided below.
= -2,700 + 20X, SYX = 65, two-tailed p value = 0.034 (for testing ß1)
Referring to Table 13-1, interpret the p value for testing whetherß1 exceeds 0.
A) For every $1 million increase in sales revenue, we expect a service charge to increase $0.034.
B) Sales revenue (X) is a poor predictor of service charge (Y).
C) There is sufficient evidence (at the a = 0.05) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).
D) There is insufficient evidence (at the a = 0.10) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).
Answer:
B
Step-by-step explanation:
Rejecting H₀, there is sufficient evidence (at the α = 0.05) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
The p-value for testing whether ß1 exceeds 0 is the probability of observing a test statistic as extreme as the one that was actually observed, assuming that the null hypothesis is true. In this case, the null hypothesis is that ß1 does not exceed 0, and the alternative hypothesis is that ß1 does exceed 0.
Since the p-value is 0.034, which is less than the significance level of 0.05, this means that there is sufficient evidence to reject the null hypothesis H₀ and conclude that ß1 does indeed exceed 0. In other words, there is sufficient evidence to conclude that sales revenue (X) is a useful linear predictor of service charge (Y).
Therefore, the correct answer is (C) "There is sufficient evidence (at the a = 0.05) to conclude that sales revenue (X) is a useful linear predictor of service charge (Y)."

What is the volume of the composite figure below? (formula for volume of a prism is 1/3 Bh where B is the area of the base.)
Answer:
Last Option; 84 cu. mm
Step-by-step explanation:
We know that;
Volume = 1/3(Bh)
And that this is figure has a square base, therefore B that represents the area of the base will be: 6 * 6 = 36
And height = 7mm
Therefore we can say;
Volume = (1/3)*(6 x 6)*(7)
Volume = (1/3)*(36)*(7)
Volume = (12)*(7)
Volume = 84
Hope this helps!
