The distance d, in meters, that a rhinoceros runs in s seconds is represented by the equation d=16s. What is the constant of pro
castortr0y [4]
Time          Distance                Distance / Time
2hrs          90 miles                  90 miles / 2 hrs =  45 miles / hr
3hrs          135 miles                135 miles / 3 hrs =  45 miles / hr
5hrs          225 miles                 225 miles / 5 hrs =  45 miles / hr
6hrs          270 miles                  270 miles / 6 hrs =  45 miles / hr

Constant of proportionality is 45 miles / hr. This is the same for the four values. The unit rate is also 45 miles / hr.

Let us assume the Distance , d is directly proportional to Time, t
d α t
d = kt 
Constant of proportionality is k which is D/T
d = 45t

Effectus [21]

Option c : 9 is the answer.

Explanation:

The expression is 1.2-(-7.8)

We need to determine the subtracted value of the expression.

From the expression we can see that the expression contains two negative signs.

To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.

This means (-) *(-) = +

Thus, the expression can be written as

1.2+7.8

Adding the two numbers, we get,

1.2+7.8=9

Thus, the value of the expression is 9.

Hence, Option c is the correct answer.

Answer:

Step-by-step explanation:

A. Two measurements(AandB)are taken on the same round.\oIs there a difference in the measurement of the muzzle velocity between device A and device B at the α=0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.

B. Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results. The confidence interval is (__,__)?

Answer:

Open chart in StatCrunch --- Stat --- T Stats --- Paired --- Enter values: Sample 1 = A, Sample 2 = B --- Click on Confidence Interval… and enter Level which is my #%. --- Compute

Beckett purchase the diamond ring in 2012 for $12,000 if the value of the rain increases by 32% each year what will the ring be
Brums [2.3K]

Answer:

$119520

Step-by-step explanation:

Given: Purchase price of Diamond ring= $12000

           Value of ring increase by 32% each year.

 

First finding number of year between 2012 and 2040, to know the time period of value appreciation.

Time period= 2040-2012= 28\ years          

∴ Time period of value appreciation is 28 years.

Now, finding the value of diamond ring increased after 28 years.

Value of ring increased after 28 years= \frac{12000\times 32\times 28}{100}

∴ Increased value of diamond ring after 28 years= $107520

Next, Value of diamond ring after 28 years= 12000+107520= \$ 119520

Hence, value of diamond ring in 2040 is $119520
