Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.

According to the question,

We have the following information:

Chris invested $5,500. The investment had a simple interest rate of 3.5%. And he plans to leave the investment alone for 12 years.

Now, we know that the following formula is used to find the simple interest on an investment:

Interest = principal*rate*time/100

Principal = $5500

Rate = 3.5

Time = 12 years

Interest = (5500*3.5*12)/100

Interest = $2310

Now, the total amount in his account will be:

5500+2310

$7810

Hence, Chris will have $7810 at the end of 12 years in his account if the simple interest rate is 3.5%.

What is the probability that a random sample of 12 second grade students results in a mean reading rate of more than 95 words pe
mihalych1998 [28]

The probability that a random sample of 12 second grade students results in a mean reading rate of more than 95 words per minute is 0.4582.

Given that the population mean, \mu = 90 wpm

The standard deviation of the population ,\sigma = 10

Sample size, n = 12

Sample mean, \bar x = 95

The reading rate of students follows the normal distribution.

Let z = \frac{\bar x - \mu}{\frac{\sigma}{\sqrt n} }

        = \frac{95 - 90}{\frac{10}{\sqrt 12} }

        = 1.732

Probability that the mean reading exceeds 95 wpm = P(\bar x >95)

                                                                                       = P(z>1.732)

                                                                                       = 1- P(z<1.732)

                                                                                       = 0.4582

[The value 0.4582 found from the area under the normal curve using tables].

Heather, brian, and austin sent a total of 97 messages over their cell phones over the weekend. Heather sent 7 fewer messages th
Nitella [24]

<u>Answer:</u>

Heather = 18 messages

Brian = 25 messages

Austin = 54 messages

<u>Step-by-step explanation:</u>

We know that Heather, Brian, and Austin sent a total of 97 messages.

Assuming the number of messages sent by Brian as x, we can say that Heather sent x-7 messages (7 fewer messages than Brian) and Austin sent 3(x-7) messages (3 times as many as Heather).

(x-7)+x+3(x-7)=97\\\\x-7+x+3x-21=97\\\\5x=97+21+7\\\\5x=125\\\\x=25

So Brian sent (x) messages =  25 messages,

Heather sent (x-7) messages = 25 - 7 = 18 messages; and

Austin sent 3(x-7) messages = 3(25-7) = 54 messages
