Paul received a coupon for 43 percent off one item at a clothing store let b be the original price of the item use the expression b-43 for the new price of the item write an equivalent expression by combining like terms
Answers
The equivalent expression for the new price of the item is 0.57b. With b be the original price of the item.
The original price of the item is represented by "b". Paul received a coupon for "43 percent" off one item at a clothing store. This means that the new price of the item will be the "original price" minus the discount. The discount is calculated by multiplying the original price by the percentage discount.
So, the discount is:
43 percent of b = 0.43 * b
The new price of the item is the original price minus the discount:
b - 0.43 * b = b - 0.43b
This expression can be simplified by combining the like terms. The like terms in this expression are b and -0.43b.
To combine like terms, we add the coefficients of the like terms:
1b + (-0.43)b = 0.57b
So, the equivalent expression for the new price of the item is:
0.57b
This means that the new price of the item is 57% of the original price. Therefore, the equivalent expression for the new price of the item is 0.57b.

Find the missing side of the triangle. 10 cm and 6 cm. What is X??????? I missed my RSM class and now this?!
Answers
The missing side of triangle is 11.66 cm, under the condition that the given triangle is a right angled triangle and the other sides of the triangle are 10cm, 6cm respectively.
In order to evaluate the other side of the triangle, we have to rely on the principles of Pythagorean Theorem which states that in a right triangle, the sum of the square sides are equal to the square of the hypotenuse side.
Then, let us consider that x be the length of the missing side then
x² = 10² + 6²
x² = 100 + 36
x² = 136
x = √(136)
x ≈ 11.66 cm
Then, the missing side of this triangle is approximately 11.66 cm.

What is 360 divided by 11.
Answers
Start by setting it up with the divisor 11 on the left side and the dividend 360 on the right side like this:
1 1 ⟌ 3 6 0
Step 2:
The divisor (11) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:
0
1 1 ⟌ 3 6 0
Step 3:
Multiply the divisor by the result in the previous step (11 x 0 = 0) and write that answer below the dividend.
0
1 1 ⟌ 3 6 0

Is Wheaties a power breakfast? A study is done in a school. 499 students agree to participate. 250 are randomized to the treatment group, and 249 to the control group. The treatment group is fed Wheaties for breakfast 7 days a week. The control group gets Sugar Pops. Final scores averaged 66 for the treatment group, the SD was 21. For the control group, the figures were 62 and 20. Which of the followings is true?
a. At level α=0.01, we fail to reject the null hypothesis, It implies that Wheaties and Sugar Pops have the same power as breakfast, at 0.01 significance level.
b. We need to test H0: μ wheaties - μ sugar pop = 0 v.s. HA: μ wheaties - μ sugar pop ≠ 0 c. At level α=0.05, we fail to reject the null hypothesis, It implies that Wheaties and Sugar Pops have the same power as breakfast, at 0.05 significance level. d. The test statistics is Z=
Answers
To determine which statement is true, we need to perform a hypothesis test to compare the mean scores of the treatment group (Wheaties) and the control group (Sugar Pops). Let's go through the steps of the hypothesis test:
Step 1: State the hypotheses:
H0: μwheaties - μsugar pop = 0 (There is no significant difference between the mean scores of Wheaties and Sugar Pops)
HA: μwheaties - μsuga pop not= 0 (There is a significant difference between the mean scores of Wheaties and Sugar Pops)
Step 2: Select a significance level:
The given options mention α = 0.01 and α = 0.05. Let's consider α = 0.05 for this analysis.
Step 3: Compute the test statistic:
Since the sample sizes are relatively large and we know the population standard deviations (SD), we can use the two-sample independent t-test. The test statistic is given by:
t = ( wheaties - X sugar pop) / sqrt((s_wheaties^2 / n_ wheaties ) + (s_sugarpop^2 / n_sugar pop))
Where:
X wheaties = mean score of the treatment group (Wheaties)
X sugarpop = mean score of the control group (Sugar Pops)
s_ wheaties = standard deviation of the treatment group
s_sugarpop = standard deviation of the control group
n_wheaties = sample size of the treatment group
n_sugarpop = sample size of the control group
Substituting the given values:
Xwheaties = 66, Xsugarpop = 62
s_wheaties = 21, s_sugarpop = 20
n_wheaties = 250, n_sugarpop = 249
t = (66 - 62) / sqrt((21^2 / 250) + (20^2 / 249))
t ≈ 4.056
Step 4: Determine the critical value:
Since we have a two-tailed test and α = 0.05, we need to divide the significance level by 2 to find the critical value. Consulting a t-table or using statistical software, the critical t-value for a two-tailed test with α/2 = 0.025 and degrees of freedom (df) = n_wheaties + n_sugarpop - 2 = 498 is approximately 1.965.
Step 5: Make a decision:
If the absolute value of the test statistic (4.056) is greater than the critical value (1.965), we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.
In this case, the absolute value of the test statistic is greater than the critical value (4.056 > 1.965). Therefore, we reject the null hypothesis.
None of the provided options is correct. The correct statement would be:
e. At level α=0.05, we reject the null hypothesis. It implies that Wheaties and Sugar Pops do not have the same power as breakfast, at a 0.05 significance level.

The area of the sail is 68 square feet, find its height and the length of the base.
Answers
Answer:
Base=8 feet
Height=17 feet
Step-by-step explanation:
Let
Base=x
Height=3x-7
Area=68 square feet
Area of the sail boat=1/2 * base * height
68 = 1/2 * x * (3x-7)
Cross product
68 * 2 =(1) * (x) * (3x-7)
136 = 3x^2 - 7x
3x^2 - 7x - 136=0
Using quadratic formula
x= -b +or- √b^2 - 4ac / 2a
= -(-7) +or- √(-7)^2 - (4)(3)(-136) / 2(3)
= 7 +or- √49 - (-1632) / 6
= 7 +or- √49+1632) / 6
= 7 +or- √1681 / 6
=7 +or- 41 /6
x= 7+41 / 6 or 7-41 / 6
=48/6 or -34/6
=8 or -17/3
Answer:
Step-by-step explanation:
Let
Base=x
Height=3x-7
Area=68 square feet
Area of the sail boat=1/2 * base * height
68 = 1/2 * x * (3x-7)
Cross product
68 * 2 =(1) * (x) * (3x-7)
136 = 3x^2 - 7x
3x^2 - 7x - 136=0
Base of the boat can't be a negative value
Therefore,
Base = x = 8 feet

Suppose a company did $2,000,000 in annual maintenance in 2013 and expects 80% of those to renew for 2014. Suppose that product sales for 2013 were $2,000,000 (which included free maintenance in 2013) and 75% of those were expected to pay an annual maintenance of 10% of the purchase price in 2014.
What will be the annual maintenance collected in 2014?
Answers
The annual maintenance collected in 2014 will be $1,750,000.
How to calculate the annual maintenance collected in 2014?To calculate the annual maintenance collected in 2014, we need to find the number of customers who will renew their maintenance contract and the number of customers who will pay for maintenance as a percentage of product sales in 2013.
Number of customers renewing maintenance in 2014 = 80% of $2,000,000 = $1,600,000
Number of customers paying for maintenance in 2014 = 75% of $2,000,000 = $1,500,000
So, the total annual maintenance collected in 2014 will be:
$1,600,000 + $1,500,000*10% = $1,750,000
Therefore, the annual maintenance collected in 2014 will be $1,750,000.

If 10g of a radioactive substance are present initially and 9 yr later only 5.0g remain, how much of the substance, to the nearest tenth of a gram, will be present after 14 yr? After 14 yr, there will be ___g of the radioactive substance. (Do not round until the final answer. Then round to the nearest tenth as needed.)
Answers
after 14 years, there will be approximately 1.97g of the radioactive substance remaining.
To solve this problem, we can use the concept of exponential decay for radioactive substances. The decay of a radioactive substance can be modeled by the equation:
N(t) = N₀ * e^(-kt),
where N(t) is the amount of substance at time t, N₀ is the initial amount of substance, e is the base of the natural logarithm, k is the decay constant, and t is the time elapsed.
In this case, we are given that the initial amount N₀ is 10g and the amount after 9 years N(9) is 5g. We can use this information to find the value of k.
5 = 10 * e^(-9k).
Divide both sides of the equation by 10:
0.5 = e^(-9k).
Take the natural logarithm of both sides:
ln(0.5) = -9k.
Solve for k:
k = ln(0.5) / -9.
Now that we have the value of k, we can use it to find the amount of substance after 14 years, N(14):
N(14) = N₀ * e^(-kt).
N(14) = 10 * e^(-ln(0.5) / -9 * 14).
N(14) = 10 * e^(14 * ln(0.5) / 9).
N(14) ≈ 10 * 0.197 = 1.97.
Therefore, after 14 years, there will be approximately 1.97g of the radioactive substance remaining.

Answers
Answer:

Anjum's height / Raja's height = 250 cm / 200 cm
To simplify this fraction, we need to find the greatest common factor (GCF) of the numerator and denominator and divide both by it. The GCF of 250 and 200 is 50, so we can simplify the fraction as follows:
(250 cm / 50) / (200 cm / 50) = 5/4

letdbe a disk in r^2 of radiusrcentered at the origin. what is the averagedistance from a point on the disk to the center?
Answers
The average distance from a point on a disk in ℝ² of radius r centered at the origin to the center is 2r/π.
To calculate the average distance, we need to integrate the distance function over the disk and divide it by the area of the disk. The distance function from a point (x, y) on the disk to the origin is given by d = √(x² + y²). Since the disk is centered at the origin, we can rewrite this as d = √(r²) = r.
Integrating this distance function over the disk involves integrating from 0 to 2π for the angle θ and from 0 to r for the radius ρ. Thus, the integral becomes ∫₀²π ∫₀ʳ r ρ dρ dθ.
Evaluating this integral gives us (2πr²)/2πr² = 1, which represents the total area of the disk. Therefore, the average distance is given by (2r/π) × (1/1) = 2r/π.

In order to meet the sample assumption associated with parametric statistics, the number of subjects needed depends on the specific statistical test being used. Generally, the rule of thumb is to have a minimum of 30 subjects in each group being compared.
However, this number may increase or decrease depending on factors such as the effect size, variability in the data, and the statistical power desired.
