Answer:

568 minutes were used

Step-by-step explanation:

95.16 - 27 = 68.16 ÷ 0.12 = 568 minutes

Nice work on answering parts (a) and (c) correctly.

I'll go over part (b) only.

We replace the C(m) with 95.16 to form the equation

95.16 = 27 + 0.12m

You have the correct equation set up. Your teacher wants you to solve for m.

So,

95.16 = 27 + 0.12m

95.16-27 = 0.12m

68.16 = 0.12m

0.12m = 68.16

m = 68.16/0.12

m = 568

If the student uses exactly 568 minutes, then the cost will be $95.16

-------------

Check:

C(m) = 27 + 0.12m

C(568) = 27 + 0.12*568

C(568) = 27 + 68.16

C(568) = 95.16

The answer is confirmed.

notka56 [123]

Answer:

200 trees

Step-by-step explanation:

Given that the temperature drops to 30 degrees F, the expected value in this situation is given by the probability of each tree sustaining damage (10%), multiplied by the total number of trees susceptible to damage (2,000 trees):

E(X) = 0.10*2,000\\E(X) = 200\ trees

The mean number of trees showing damage is  200 trees.

Can someone help? 20 points!
Ann [662]

a)

   V = \frac{4}{3} \pi r^{3}

905 = \frac{4}{3} \pi r^{3}

2715 = 4π r³

\frac{2715}{4\pi } = r^{3}

216 = r³

\sqrt[3]{216} = \sqrt[3]{r^{3} }

 6 = r

b)

i = (\frac{p1}{p2} )^{\frac{1}{n}} - 1

i = (\frac{200,000}{3,000} )^{\frac{1}{(2012-1945}} - 1

i = (\frac{200}{3} )^{\frac{1}{(67}} - 1

i = (66.67)⁰¹⁵ - 1

i = 1.065 - 1

i = 0.065

i = 6.5%

Answers: r = 6, i = 6.5%

A house on the market was valued at $263,000. After several years, the value increased by 19% By how much did the house's vaule
VARVARA [1.3K]

The house's value increased by $49,970. The current value of the house is $312,970.

Step-by-step explanation:

Step 1:

The house was valued at $263,000 and this value increased by 19%. So we need to calculate how much 19% of $263,000 is.

To do so we convert the 19% into a fraction by dividing it by 100 and multiplying it with the house's value.

19% of $263,000 = \frac{19}{100} (263,000) = 0.19(263,000)=49,970.

So the value of the house increased by $49,970 in several years.

Step 2:

To calculate the current value, we add the increased value to the original value.

The current value = the past value + The increased value,

The current value =263,000 + 49,970 = 312,970.

So the current value of the house is $312,970.
