<h2>It represents that , the amount of money in the bank account is $1680 after 50 months.</h2>

Step-by-step explanation:

Given , the amount of money in a bank account can be represented by the equation A(m) = 30m +180, where A(m) is measured in dollar and m is measured in month.

When A(m) = 1680

1680 = 30m +180

⇔30m = 1680 -180

⇔30m = 1500

⇔m= \frac{1500}{30}

⇔ m = 50

It represents that , the amount of money in the bank account is $1680 after 50 months.

PLEASE HURRY WILL GIVE BRAINLIEST A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $70
rjkz [21]

Answer:

  40 miles a day

Step-by-step explanation:

The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:

  A: 90 + 0.30·40 = 102

  B: 70 + 0.80·40 = 102

The body temperatures of adults have a mean of 98.6°F and a standard deviation of 0.60° F. Describe the center and variability o
amid [387]

Answer:

center = 98.6, variability = 0.08

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}

The center is the mean.

So \mu = 98.6

The standard deviation of the sample of 50 adults is the variability, so

s = \frac{0.6}{\sqrt{50}} = 0.08

So the correct answer is:

center = 98.6, variability = 0.08

Explain how you would create and use a spinner to simulate the probability of an event with the following probabilities:
castortr0y [4]

To simulate the probability in a spinner divide the spinner into colors depending on the probability each color represents.

<h3>What does the word "probability" mean?</h3>

This word refers to the likelihood for an event to occur. Moreover, it is often expressed either as a fraction, a percentage, or a number.

<h3>How to create a spinner to simulate probability?</h3>

In this case, each of the colors represents a probability:

  • Green 20%
  • Blue 1/4 or 25%
  • Yellow 2/5 oe 40%
  • Orange 15%

Due to this, the best is to divide the spinner by colors and considering the percentanges of each color. For example 40% of the spinner should be red, while 15% should be orange.

Using the right triangle below. What is the name for side AC ?
irga5000 [103]

Answer:

B) Adjacent

Step-by-step explanation:

The hypotenuse will ALWAYS be designated as the longest side in a right triangle.

Pretend that the angle (the one with the round line) is an eyeball that is looking outwards. The eye is looking out at side BC. That means that line BC is opposite of the angle.

This leaves one side left: the adjacent side. The adjacent side is the side next to the angle. But it is the side that is NOT the hypotenuse.
