50 text messages

let m = the number of months
let t = each message sent

25m + 0.1t = 80

plug 3 in for m (because 3 months)
25(3) + 0.1t = 80

simplify
75 + 0.1t = 80

subtract 75 from 80
0.1t = 5

divide 5 by 0.1
t = 50

answer: 50 text messages

Suppose you have a sample of size 42 with a mean of 30 and a population standard deviation of 7.4. What is the maximal margin of
9966 [12]

Answer:

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

Step-by-step explanation:

We have given,

The sample size n=42

The sample mean \bar{x}=30

The population standard deviation \sigma=7.4

Let \alpha be the level of significance = 0.05

Using the z-distribution table,

The critical value at 5% level of significance and two tailed z-distribution is

\pm z_{\frac{0.05}{2}}=\pm 1.96

The value of margin of error is

ME=z_{\alpha/2}(\frac{\sigma}{\sqrt{n}})

ME=1.96(\frac{7.4}{\sqrt{42}})

ME=1.96(1.1418)

ME=2.238

The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.

Steve makes the tree diagram shown to find the possible outcomes of tossing a penny, a nickel, and a dime. What is the probabili
stiks02 [169]
Hi there!

Since there is a 50% chance of any coin landing on heads and a 50% chance of any coin landing on tails, the chance that all 3 coins land on either heads or tails (the same side) is 50% * 50% * 50%.

50% * 50% * 50%
= 0.5 * 0.5 * 0.5
= 0.25 * 0.5 
= 0.125

Now, we need to convert into a percentage:

0.125 = 12.5%

So, the answer is 12.5%.

Hope this helps!
