Which ratio is equivalent to 3/15 ?

Answer: Samantha

Step-by-step explanation:

Two ways you could solve this percents or fractions.

Percents

Peter: 4/5 = 80%

Samantha: 7/8 = 87.5%

Fractions

Set the denominator equal to each other

the common denominator would be a multiples to both 5 and 8 which is 40.

Peter: 4/5 = 32/40 because 5 times 8 is 40 and what you do to the denominator you do to the numerator so 4 times 8 is 32.

Samantha: 7/8 = 35/40 because 8 x 5 = 40 and 7 x 5 = 35.

Then compare and 35/40 is greater so Samantha.

a) The time required to assemble the 8th unit is 0.876 hours.

b) The total time required to assemble the last 5 units is 1.752 hours

(a) the time required to assemble the 8th unit.

To solve this, we can first find the time required to assemble 7 units and then subtract it from the time required to assemble 8 units.

Time required to assemble the first unit = 3 hours

Given, the time required to assemble the 6th unit = 1 hour and 23 minutes = 1 + 23/60 hours = 1.383 hours

Average time required to assemble 1 unhours production= [(time required to assemble the first unit) + (time required to assemble the sixth unit)]/5= [(3) + (1.383)]/5= 0.876 hours

Time required to assemble 7 units= 7 × 0.876= 6.132 hours

Now, time required to assemble the 8th unit= Time required to assemble 8 units - Time required to assemble 7 units= 8 × 0.876 - 6.132= 7.008 - 6.132= 0.876 hours

(b) the total time required to assemble the last 5 units.

We have already calculated the time required to assemble the first 6 units.

Time required to assemble the first 6 units= 6 × 0.876= 5.256 hours

Now, the total time required to assemble the last 5 units= Time required to assemble 8 units - Time required to assemble the first 6 units= 8 × 0.876 - 5.256= 7.008 - 5.256= 1.752 hours

Cash received for interest during  2014 was $3,500 .The following equation can be used to determine the amount of money received as interest in 2014:

Amount received as interest equals Interest Income for 2014 plus the decline in Interest Receivable

The difference between the balance of interest receivable at December 31, 2013, and at December 31, 2014, can be used to calculate the decline in interest receivable:

Reduced interest due = Interest due at December 31, 2013, minus Interest due at December 31, 2014, which equals $1,100 minus $1,400, or -$300.

The fact that the balance of interest receivable increased from 2013 to 2014 indicates that the company produced more interest money during the year than it received. In light of this, the money earned on interest in 2014 is:

Interest income from 2014 plus a decrease in interest receivable equals $3,200 minus (-$300) to $3,500 in interest payments received.

Hence, $3,500 is the correct response (C).

Heritability is a statistic that quantifies the proportion of observed variance in a group of individuals that can be attributed to genetic variance.

Heritability is a fundamental concept in genetics and behavioral sciences that helps understand the extent to which genetic factors contribute to observed variations in a particular trait within a population. It measures the proportion of phenotypic variation (differences in traits) that can be explained by genetic variation. Heritability estimates range from 0 to 1, where a value of 0 indicates that all observed variation is due to environmental factors, and a value of 1 suggests that all observed variation is due to genetic factors.

To calculate heritability, researchers typically study populations with varying degrees of genetic relatedness, such as twins or family members. By comparing the similarity of traits between individuals with known genetic relatedness, it is possible to estimate the contribution of genetic factors to the observed variance. Environmental factors that contribute to phenotypic variation are considered as part of the non-genetic or "environmental" component.

It is important to note that heritability estimates are population-specific and apply only to the particular group being studied. Additionally, heritability does not provide information about specific genes or the precise mechanisms by which genetic factors influence traits. Nonetheless, heritability serves as a valuable tool in understanding the relative importance of genetic and environmental factors in shaping individual differences within a population.

To evaluate the triple integral ∭ √(x^2 + y^2) dV using cylindrical coordinates, we need to express the integrand and the volume element in terms of cylindrical coordinates.

In cylindrical coordinates, we have:

x = ρcos(θ)

y = ρsin(θ)

z = z

The volume element in cylindrical coordinates is given by:

dV = ρ dz dρ dθ

Now let's substitute these expressions into the integrand:

√(x^2 + y^2) = √((ρcos(θ))^2 + (ρsin(θ))^2) = √(ρ^2(cos^2(θ) + sin^2(θ))) = ρ

Therefore, the triple integral becomes:

∭ ρ ρ dz dρ dθ

To evaluate this integral, we need to determine the limits of integration for each variable.

For ρ, it depends on the region of integration. Let's assume the region is bounded by ρ = a and ρ = b, where a and b are constants.

For θ, it typically ranges from 0 to 2π (a full revolution).

For z, it depends on the height of the region, so let's assume the limits are from z = c to z = d, where c and d are constants.

The integral becomes:

∫∫∫ ρ ρ dz dρ dθ

Integrating with respect to z first:

∫(c to d) ∫(a to b) ∫(0 to 2π) ρ ρ dθ dρ dz

Integrating with respect to θ:

∫(c to d) ∫(a to b) [(1/2)ρ^2] (2π) dρ dz

Simplifying:

2π ∫(c to d) ∫(a to b) (1/2)ρ^2 dρ dz

Integrating with respect to ρ:

2π ∫(c to d) [(1/6)ρ^3] (a to b) dz

Simplifying:

(2π/6) ∫(c to d) [(b^3 - a^3)] dz

(π/3) ∫(c to d) [(b^3 - a^3)] dz

Evaluating the integral with respect to z:

(π/3) [(b^3 - a^3)] (d - c)

So, the value of the triple integral ∭ √(x^2 + y^2) dV using cylindrical coordinates is (π/3) [(b^3 - a^3)] (d - c).

The government's purchase of new weapons systems has a ripple effect that stimulates economic growth. When the government buys weapons systems from manufacturers, it injects money into the industry, enabling manufacturers to pay their employees.

These employees then spend their earnings on various goods and services, which benefits other businesses. As a result, those businesses can hire more employees and contribute to the expansion of the local economy.

This process can be understood through the concept of the multiplier effect. The initial government spending on weapons systems creates a chain reaction of increased economic activity. The manufacturers, upon receiving payment, allocate those funds to employee salaries, thereby boosting the income and purchasing power of their workers.

These employees, in turn, utilize their income to make purchases from different firms, such as grocery stores, restaurants, or service providers. Consequently, these businesses experience a rise in demand, allowing them to hire more employees to meet the increased consumer needs. This cycle continues, leading to a broader expansion of the local economy as money circulates and creates additional income and employment opportunities.

The statement, "A p-value for correlation which is statistically significant implies the correlation is due to random chance" is FALSE.

When the p-value is statistically significant, it indicates that the correlation is not due to random chance but rather has a true association. A p-value refers to the probability of obtaining the observed result due to chance alone.
Correlation refers to the relationship between two variables. A correlation coefficient is used to measure the strength and direction of the relationship between the two variables.

A correlation coefficient of +1 or -1 indicates a perfect correlation, while a coefficient of 0 indicates no correlation. A correlation coefficient that falls between these values indicates a partial correlation.
What is p-value?A p-value refers to the probability of obtaining the observed result due to chance alone. A statistically significant p-value is typically one that is less than or equal to 0.05.

In other words, if the p-value is less than 0.05, then there is less than a 5% chance that the observed correlation is due to random chance alone. Therefore, it is concluded that the correlation is significant and not due to chance.
In conclusion, a statistically significant p-value indicates that the correlation between two variables is not due to random chance but rather has a true association. The statement that a p-value for correlation which is statistically significant implies the correlation is due to random chance is false.

Therefore, based on the information given, it seems that Bus Company A is doing slightly better in terms of on-time performance.

To determine which bus company seems to be doing better, we need to compare their on-time performance.

Bus Company A claims that it is typically on time 95% of the time. This means that out of 100 trips, it expects to be on time for 95 of them.

On the other hand, Bus Company B has a record of being on time 47 days out of the 50 days that it operates. This means that its on-time performance is:

47/50 = 0.94 or 94%

Comparing the two percentages,

we can see that Bus Company A claims to have a higher on-time performance (95%) than Bus Company B's actual on-time performance (94%).  Bus Company B's on-time performance is based on actual data from 50 days of operation.

Therefore, based on the information given, it seems that Bus Company A is doing slightly better in terms of on-time performance.
